Nikon has announced an inexpensive macro lens aimed at entry-level DSLR users. The AF-S DX Micro Nikkor 40mm f/2.8G offers true 1:1 macro in a compact, lightweight package. With its inbuilt silent wave motor it will autofocus on all Nikon DSLRs, including those that lack in-body AF motors such as the D3100 and D5100. It uses an internal focus system with close-range correction to attain a minimum focus distance of just 16cm / 6.4", equating to approximately 5cm / 2" from the front of the lens. It will be available from 25th August, at an MSRP $279.95.

Just posted: Our in-depth review of the Panasonic Lumix DMC-G3. The G3 is Panasonic's smallest EVF-equipped G-series camera so far, and also the second highest-resolution in the range. At the core of the G3 is a brand new 15.8MP sensor, making it the first mass-market model to step away from the ageing 12MP chip. Like the G2, it features an articulated, touch-sensitive LCD screen but inherits its interface from the GF2 to make the camera ever-more accessible to beginners. On paper, the G3 is an appealing combination of enthusiast-oriented specification and beginner-friendly ergonomics - read our in-depth review to find out how it performs.

The AVCHD video format specification has been updated to include 1080 60p and 50p video. The AVCHD 2.0 standard has been approved by Sony and Panasonic - the co-promoters of the format. The move also includes additional support for high definition 3D movies in the format. Up until now, both companies have made high-end camcorders that incorporated out-of-specification 60p video in what was otherwise an AVCHD arrangement.

Kenko-Tokina has bought French filter maker Cokin. Cokin's parent company went into administration in November 2010, with supplies of the company's products becomingly increasingly scarce. The Japanese lens and accessory maker has said it will retain the square filter specialiast as an independent company, rather than simply utilizing the well-recognized brand-name.

Just Posted: our revised Fujifilm X100 review. Amongst the changes listed in Fujifilm's 1.10 firmware update for the FinePix X100 were several that addressed issues raised in our original in-depth review. To reflect this, we have gone back into the studio and re-tested the X100 to see just how much difference the changes make. Does the update allow the X100 to achieve its obvious potential as a high-quality luxury compact camera, or is it still too quirky to earn our outright recommendation? Read our extensively updated review to find out.

Japanese website DCWatch has published a test of the star tracking feature of Pentax's O-GPS module. The Astro Tracer mode uses the GPS coordinates to calculate the camera's movement relative to the stars, then utilizes the camera's image stabilization system to shift the sensor to track that movement. The report, which is a little tricky to follow in its Google-translated form, includes several example images, showing the system's effectiveness. (From DCWatch)

SLR Magic has launched a 26mm F1.4 manual focus 'toy' lens for Micro Four Thirds. The 52mm equivalent lens comes with replaceable aperture and focus rings, seven colors of which are supplied. Panasonic owners looking longingly at Olympus' Art Filters (or PEN owners wanting to avoid the associated frame lag) might enjoy the toy-lens shooting experience. The lens is available from Japanese website Gizmoshop, which has placed a series of sample images on photo sharing site Flickr. (From DCWatch)

We've added three additional images to our samples gallery for the Olympus E-P3 with revised processing. Following concerns expressed about the levels of noise reduction and sharpening being applied by the camera's default settings, we have re-processed the images with the sharpening and noise reduction minimized. Having confirmed that re-processing raw files in-camera gave the same results as shooting natively at these settings, we re-processed three of our gallery images to allow side-by-side comparison with the default settings.

The head of Fujifilm's camera division has suggested the company may make a return to interchangeable lens cameras. In an interview with news agency Reuters, Takeshi Higuchi stressed the importance of launching 'luxury' models to help establish the company as a high-profile brand. In addition he discusses the company's reasoning for looking beyond China for manufacturing. However, his comments about having the in-house capabilities to develop its own cameras may reduce the speculation about the company producing models for pre-existing camera systems.

Hoya has sold the Pentax camera division to Ricoh. The Pentax Imaging Systems Division will be spun-out as a new company and its shares transfered to Ricoh on October 1st. The deal will also include the Pentax camera manufacturing subsidiary in Vietnam. A public announcement from Hoya explains that Ricoh is looking to build a consumer cameras business and wanted Pentax's interchangeable lens camera technology, lens technology and sales channels. Its plans for the business specifically include the interchangeable lens camera market. Hoya will retain the other Pentax businesses, such as medical devices, that it gained in its 2007 takeover. Terms of the deal were not disclosed but Japanese business paper Nikkei Business Daily reports a price of about 10 billion yen ($124.2 million).

Olympus has launched the E-P3, its fifth generation Micro Four Thirds camera. The P3 features a familiar-looking PEN body and revised 12MP sensor but almost every other aspect of the camera has changed. The latest flagship PEN features what the company claims to be the world's fastest AF-S performance, as well as a 614,000 dot VGA-equivalent OLED touch-sensitive screen and built-in flash. In addition it can shoot 1080i60 HD movies in the AVCHD format. We've been using the E-P3 for a while now and have prepared a full preview with studio and real-world sample images.

Alongside the PEN E-P3, Olympus has announced the PEN Lite and PEN Mini. These closely-related sister models (formally called E-PL3 and E-PM1) feature similar specifications but smaller bodies that borrow heavily from the styling of the company's XZ-1 enthusiast compact. Both cameras are aimed at the point-and-shoot upgrader and feature 460,000 dot LCDs, rather than the E-P3's OLED display but otherwise retain much of that camera's capability, including what's claimed to be the world's fastest AF. We've been using a PEN Lite for a while and have prepared a brief hands-on preview.

Alongside its three PEN bodies, Olympus has announced the M. Zuiko Digital ED 12mm F2.0 and M. Zuiko Digital ED 45mm F1.8 prime lenses for Micro Four Thirds. The 12mm F2.0 is a metal-bodied 24mm equivalent featuring a unique snap-focus manual focus mode. A snap-back focus ring reveals a traditional depth-of-field scale for 'zone' focusing and offers improved focus 'feel.' Later in the year it will be accompanied by the 45mm F1.8 portrait lens, making Olympus one of the only manufacturers to offer a fast prime at a roughly 100mm equivalent focal length, ideally suited to portraiture. There is also a relatively compact, bouncable and remotely commandable flash, the FL-300R, helping the PEN range look more like a complete system. More details of the 12mm F2.0 are included in our E-P3 preview, along with a gallery of sample images.

Leica has released a firmware update for its M8 rangefinder camera. Version 2.014 adds support to the recently released Super-Elmar-M 21 mm f/3.4 ASPH. wide-angle lens amongst other improvements. The firmware is available for immediate download from the company's website.

Sigma has announced pricing and availability for its 105mm F2.8 EX DG OS HSM Macro lens. The optically stabilized version of the lens, originally announced back in February, is available now with a recommended selling price of $1,400. The 105mm F2.8 EX DG OS HSM offers true 1:1 macro reproduction, and uses a floating focus system to maintain high optical performance at all distances.

Newly merged Kenko-Tokina has quietly launched the Tokina SD 17-35mm F4 AT-X PRO FX, a semi-fast wideangle zoom for full frame cameras. The company says the F4 maximum aperture makes it easier to produce a smaller lens with fewer aberrations, to sit alongside its 16-28mm F2.8 PRO. The lens features 'SD' glass that the company says offers similar properties to fluorite elements as well as its 'silent drive module' AF motor and high-precision AF position sensor for fast, accurate focusing. No details of pricing or availability are yet available from the company's distributors outside Japan.

Fujifilm has released the promised fimware update for its X100 large sensor compact. Firmware v1.10 includes 22 feature modifications and additions, including correction of several issues highlighted in our review of the camera. The company has detailed the changes and revised the user manual to reflect additional features added as part of the update. Both the firmware update and the updated user manual can be downloaded from the company's website immediately.

Pentax has announced the 'Q' mirrorless interchangeable lens camera. The camera is the first to use the company's Q mount and features a compact-camera-sized 1/2.3" image stabilized CMOS sensor. This is wrapped in a magnesium alloy body with a distinctly rangefinder-esque design but distinctly compact sizing. Its feature set ranges from the 1080p30 movie shooting (with H.264 compression), to a series of fun filters that can be applied to the Quick Dial on its front plate. We've had a chance to play with a pre-production Pentax Q and have prepared a quick preview.

Pentax has announced four additional lenses for its new Q mount. As well as the kit 47mm equivalent F1.9 '01 Standard Prime' lens that will come with the camera, the company has also announced the '02 Standard Zoom' that will offer 28-83mm equivalent focal lengths. Alongside these will be three more affordable, fun lenses. The 03 Fisheye, 04 Toy Lens Wide and 05 Toy Lens Telephoto are designed to make accessible the creativity that interchangeable lenses can bring. The latter three lenses are all manual focus and fixed aperture to keep costs down.

Startup company Lytro is claiming to be close to launching a camera that allows any point of focus to be specified after the shot is taken. The concept behind the device, called a light-field, or plenoptic camera camera has surfaced regularly over the past few years, but now Lytro, founded by Stanford PhD Ren Ng, says it will have a product ready within a year. The concept uses a series of microlenses to split the incoming light rays across multiple sensor pixels, depending on the angle from which it arrived. This additional information about the angle of the arriving light makes it possible to recalculate different focus points after the image has been shot, but at the cost of lower image resolution. The company hasn't, as yet, provided details such as its system's output resolution. (From the New York Times)

Fujifilm Canada has released details of the forthcoming X100 firmware update on its '@fujiguys' Twitter feed. A series of updates detail ten significant changes to the X100's firmware, designed to address some of the criticisms of the camera's behavior. Changes include more responsive 'wake from sleep' behavior without a long press of the shutter button, clear indication of the eye sensor being engaged and the maintaining of ISO/Self-Timer/DR/Flash/Macro settings when exposure mode, review mode or power state is changed. The original messages can be found at http://twitter.com/#!/fujiguys but, as yet, no official announcement of when the updated firmware will become available has been made.

Apple has announced Final Cut Pro X, the latest version of its popular high-end video editing software. Final Cut Pro X features a trackless canvas, that Apple is calling a 'Magnetic Timeline' for flexible arranging and editing of clips. It's also possible to 'audition' different combinations of clips to make it easier to choose between multiple takes. The software also features improved tagging (including auto-analysis of clips) to make it easier to manage and locate the clips you want to use. Final Cut Pro X is available from the Mac App Store for $299/£179.

Leica has announced the M9-P, a variant of its 18MP full-frame M9 rangefinder camera. The P version gains the sapphire crystal LCD glass previously seen on the Leica M8.2 but now featuring improved anti-reflective coatings for improved visibility in difficult lighting conditions. In order to give an understated appearance, the M9-P omits the traditional Leica red dot and M9 designation from the front of the camera, instead the Leica name is engaved in the metal top-plate in the company's traditional script.

Leica has announced the Super-Elmar-M 21mm f/3.4, a wideangle prime for its M-series rangefinder cameras. Weighing in at less than 10 ounces, it's extremely compact at just under 2 inches in length. It has a minimum focus distance of 0.7m, and uses a dual-sided aspheric element and 4 anomalous partial dispersion elements in its optical construction. On the M8 camera it offers an angle of view equivalent to a 28mm lens. It will be available from June 2011 at a price of £2025.

Pentax, Sony, Leica and Ricoh have released firmware updates for several of their cameras. Pentax has updated the firmware for its K-r, K-5 and 645D. Firmware v1.10 for all three cameras brings compatibility with the recently-announced 0-GPS module. Sony, meanwhile, has created updates for its NEX-3 and NEX-5, and SLT A33 and A55 models, adding many of the features of its forthcoming NEX-C3 and SLT A35 cameras. Leica has updated the firmware for its M9 digital rangefinder to improve color consistency across the frame when used with wide-angle lenses. Finally, Ricoh has updated its G700 and G700SE rugged industrial cameras. Click here for links to the updates.

Just Posted: Our samples gallery from the Panasonic Leica DG Summilux 25mm F1.4 ASPH. We've had the chance to borrow a production example of this fast 50mm-equivalent lens and have prepared a samples gallery to show some of what it can do. We've also shot a couple of comparisons against the popular Lumix G 20mm F1.7 ASPH to see how the two lenses compare when used wide open, and give some idea of what the slightly longer focal length and wider aperture mean in terms of background defocus and subject isolation. Updated with additional comparison shots.

Lens rental company Lensrentals has posted an interesting blog post on the subject of filters. Ostensibly side-stepping the issue of whether UV filters are actually beneficial, it illustrates the effect of stacks of UV filters of different qualities. Acknowledging this isn't a real-world application, it does show that, if you are going to use filters, you probably shouldn't try to skimp on them. The post also shows exactly why you should never be tempted to stack more than 49 filters on the front of your lens.

Panasonic, FujiFilm and Casio have all released firmware updates for compact camera models. Casio has updated firmware for its ZR100, ZR10, H20G and TRYX models, mainly improving compatibility with the long obsolete Mac OS 9. Panasonic meanwhile has improved the 'menu indications' for the FP3 and FH22/FS33 models. Finally, Fujifilm has adjusted the image sharpness and saturation of its XP20/XP22, XP30 and Z90/Z91 models, as well as making improvements to playback mode.

DxO Labs has launched FilmPack 3, the latest version of its silver halide film simulation software. The software now includes the ability to mimic up to 60 famous black and white, and color films, based on calibration from professional prints, giving what the company claims is the most precise film simulation on the market. Version 3 adds new film looks and color filters. It also brings a greater degree of control, including HSL sliders, a channel mixer for optimizing Black and White conversions and, at customer request, the ability to add vignetting. Custom film styles can also be created by mixing the color response of one film with the grain pattern of another. The software is available as standalone software or plugins for DxO Optics Pros, Photoshop, Lightroom or Aperture.

DxO Labs has launched Optics Pro v6.6, an updated version of its raw processing and correction software. Version 6.6 adds more noise control options along with a color control slider and support for extra cameras, including Panasonic's GF1 and GF2. The update means all the JPEG corrections available for fully-supported cameras can now be manually applied to images from unsupported cameras. It also provides compatibility with the simultaenously-released FilmPack 3. Users who've purchased DxO Optics Pro since 1 June 2009 get the upgrade for free while a 30% discount is available at launch.

Just posted: Our quick review of Nik's Snapseed app for the Apple iPad. Nik is one of the better-known names in photographic software, and at the heart of its various plugins is U Point - an automatic masking tool that allows you to pinpoint specific areas of an image for manipulation. Snapseed is an app for the Apple iPad that brings this U Point technology to the touchscreen iOS platform. It features a wide range of effects filters, as well as more conventional adjustments like crop, rotate and 'organic frames'. At $4.99/£2.99/€3.99, Snapseed is considerably cheaper than Nik's desktop software, but can it even approach the same versatility? Read our quick review to find out.

Adobe has issued updates for its recently released apps for iPad that integrate with Photoshop. All three apps, originally launched in May 2011, have been revised and have had features added to them. Adobe Nav, the remote file browser and tool selector, for instance now has the ability to transfer images from an iPad photo library into Photoshop CS5 for editing. The updated apps are available for download from Apple's App Store now.

Panasonic has announced the much-leaked DMC GF3 compact mirrorless camera. The latest Micro Four Thirds model continues the company's move towards smaller, easier-to-use cameras. The GF3 has the same 12MP sensor as its predecessor but with a faster processor enabling rapid 120Hz autofocusing. The camera gains the Photo Styles and Creative Controls color and processing options from the G3 but loses several physical features from the GF2. We've had a GF3 in the office and have prepared a preview that looks at what these changes mean in terms of actually using the camera.

Panasonic has announced its long-anticipated Leica Summilux DG 25mm F1.4 lens for the Lumix G system. Also known as the H-X025, it's the company's second premium Leica-branded lens for Micro Four Thirds, and the first to employ Nano Surface Coating for more efficient reduction of flare. It employs nine elements in seven groups, including two aspherical elements and one UHR (Ultra High Refractive) glass element, and a rounded 7-bladed aperture diaphragm designed to render pleasingly-blurred backgrounds. It will be available from August 2011, at a price to be announced.

Canon has announced an updated version of its 55-250mm image stabilized telephoto zoom. The EF-S 55-250mm f/4-5.6 IS II is a cosmetically refreshed version of the existing 55-250mm IS, launched in 2008. A consumer-grade tele zoom, it will be available on its own or alongside the recently updated 18-55mm f/3.5-5.6 IS II as a two lens kit with the EOS 550D (Rebel T2i), EOS 600D (Rebel T3i) or EOS 60D.

Just posted: our quick review of the Lensbaby Composer Pro and Sweet 35 optic. Lensbaby has never played by conventional photographic rules. Long a manufacturer of quirky, low cost (and distinctly 'lo-fi') optical accessories, its product line has evolved to include more 'serious' products. The recently launched Lensbaby Composer Pro and Sweet 35 optic promise better build-quality, better exposure control and better glass than previous offerings, and as such, we were keen to try them out. So has Lensbaby lost sight of its grungy, lo-fi beginnings, or can these new products breathe new life into the concept and introduce Lensbaby to a more 'serious' audience? Read our quick review to find out.

Ricoh has announced the PX rugged, waterproof compact. It combines a 16MP stabilized CCD sensor and 2.7" LCD with conventional camera styling. Despite its appearance, it can withstand a drop from up to 1.5m and being submerged to a depth of 3m for 60 minutes. Along with the camera, Ricoh has launched a range of silicone covers that help make the camera still-more durable. We've had access to a pre-production PX and have prepared a brief preview and 20-image samples gallery.

Sony has announced the SLT A35, the latest addition to its innovative range of fixed-mirror DSLRs. The A35 replaces the A33 and features a new 16.2MP EXMOR APS-C CMOS sensor. The chip has been redesigned to improve power consumption, promising improved battery and thermal performance. The A35 can shoot 1080i60 video and shoot 7 frames per second at 8.4MP (a 1.4x crop from the middle of the sensor that Sony is calling Tele-zoom High Speed Shooting). The camera also gains 'Picture Effects' processing filters that will be offered to existing A33 and A55 owners in a forthcoming firmware update. We've been using a pre-production version of this latest SLT and have prepared a hands-on preview and samples gallery.

Sony has added the NEX-C3 to its range of mirrorless interchangeable lens cameras. The C3 features the same 16.2MP seen in the SLT A35, again promising improved battery life. The latest model is directly aimed at offering a compact-camera-like experience to users looking to upgrade to a large-sensor camera. It also features the 'Picture Effects' processing filters that will be available to NEX-3 and NEX-5 owners as a firmware update. The NEX-C3 will be available as a kit with the 18-55mm E-mount lens for around $649 or $599 with the 16mm F2.8 lens. A more powerful external flashgun for the NEX system is also being announced. The HVL-F20S has a guide number of 20 (m, 50mm/ISO 100) and will be available from October at around $150. We've had the chance to prepare a hands-on preview of the NEX-C3, including a samples gallery.

Sony has announced its fourth lens for NEX cameras, in the shape of the E 30mm F3.5 macro (or SEL30M35). Billed as the world's lightest macro for interchangeable lens cameras capable of life-size 1:1 magnification, it uses internal focusing to achieve a minimum working distance of less than an inch from the front of the lens. It also promises quiet autofocus for both stills and video use. The lens will be available in October at a suggested retail price of around $250. We've had a pre-production example that we've used to prepare a samples gallery.

Sony has given more details of the forthcoming firmware updates for A33, A55 Nex-3 and NEX-5 owners. The updates, which will be available from June 20th, include many of the features built into the newly-announced SLT-A35 and NEX-C3. These include the Picture Effects processing modes and many of the small handling improvements incorporated into the newer models.

Apple has announced details of the forthcoming versions of its iOS operating system for iPhone, iPad and iPod Touch. With these devices ranking among the most used on popular photo-sharing sites, it comes as no surprise that several new features in iOS5 are specifically aimed at photographers. These including additional camera features for the iPhone/iPod Touch and iPad2, such as the ability to overlay thirds gridlines, and wireless syncing of photographs between iOS devices using Apple's new iCloud service.

Pentax has launched an add-on GPS module for its recent DSLRs that allows simple geotagging of images. The O-GPS1 unit attaches to the camera's hotshoe, allowing the camera to add latitude, longitude, altitude, UTC capture time and direction as image metadata. This data can be used to place images in mapping software such as Google Earth or as a means of file organization and retrieval. K-5 and K-r users also gain access to the 'Astrotracer' feature that predicts the movement of celestial objects and uses the sensor shift mechanism to track this movement to give astrophotographs with single points, rather than star-trails. The O-GPS1 unit will be available from mid June at a recommended price of $249.95/£229.99.

The Sony World Photography Awards have started accepting entries for the 2012 competition. The award categories have been revised for the latest competition and are split between 'professional' and 'open' categories. Submitted photos must be taken during 2011 and can be submitted at any point between now and Jan 4th 2012. Enthusiast photographers are welcome to enter either the professional or open competitions but not both. 2012 sees the introduction of a youth competition in which photographers under the age of 20 can submit images that suit the themes: 'environment,' 'portrait' or 'culture.' The latest competition also sees the addition of six moving image categories.

Nikon is promoting its latest US TV advert starring Ashton Kutcher, pointing out that the spot was filmed using the D5100 it promotes. This isn't the first time such a claim has been made, of course - Olympus promoted its PEN series of mirrorless cameras with adverts shot using its product. Still, it makes clear what's possible with the latest generation of 1080p-shooting DSLRs, if you're an award-winning director of photography with access to professional actors.

Sigma has announced the pricing and availability of the stabilized versions of its 120-300mm F2.8 telezoom lens. The 120-300mm F2.8 EX DG OS APO HSM will have an MSRP of $4,700. The lens, which features Sigma's latest FLD low-dispersion glass is available now in Canon, Nikon and Sigma mounts.

Just Posted: Our review of the Nikon Coolpix P300. The P300 is interesting in the way it straddles camera classes - offering enthusiast camera features such as twin control dials and PASM shooting modes but built around a smaller sensor than its apparent peers. This smaller sensor and inability to record Raw files mark it out from the likes of the Canon S95 and Samsung's EX1 but, then again, so does its much more affordable price tag. So does this leave the P300 with the right balance of price and capability or leave it falling short of expectations? Read our concise review to find out...

Fujifilm is to update the firmware of its X100 large-sensor compact camera to address some of the criticisms raised in our review. The statement from Fujifilm Japan says: 'Fujifilm is planning to release a new version of firmware in the near future. The new firmware will include and respond to some of functionality posted by dpreview.' We will, of course, revisit our review in the light of these changes, when the update becomes available.
