DxOMark has tested 61 lenses on the Nikon D800, and drawn some conclusions about the results. So far it has published two sections of an eventual four-part article: the first discusses how much benefit the D800's 36MP sensor really offers over the 24MP chips in cameras such as the D3X and D600, while the second looks at which lenses in the 50-100mm range come out with the best DxOMark scores. Further parts later this month will look at telephoto and wideangle lenses. Click through for the link.

Nikon has offered a behind-the-scenes look at its lens manufacturing process. The YouTube video follows the process from creating the glass through to final assembly and has been posted to celebrate the 80th anniversary of its Nikkor lenses. The company has also listed out few milestones of the brand's history, which started with the Aero-Nikkor aerial photography lenses in 1933. Click through to watch the video.
CP+ 2013: Nikon has several samples of its 18-35mm F3.5-4.5G ED consumer-level wide-angle full-frame zoom on show, while Sigma has re-designed and re-worked several of its most interesting lenses, which are being shown in prototype form at its stand. This includes a new version of its 30mm F1.4 for APS-C DSLRs. And, while none are available to shoot with yet, we got a chance to handle them, along with the portrait-friendly Sigma DP3 Merrill.
CP+ 2013: Tamron is showing off its newly-announced 14-150mm F3.5-5.8 Di III VC stabilized superzoom lens for Micro Four Thirds, while Olympus has a revised version of its 75-300mm F4.8-6.7. Though Tamron hasn't yet announced the price or availability of the 14-150mm, the prototype it has on display is working and the company gave us a hint about how much it will charge.
Tokina has announced it will be exhibiting two soon-to-be-released lenses at the CP+ trade show in Japan. The AT-X 70-200 F4 PRO FX VCM-S is a telephoto zoom that's designed for use on both full frame and APS-C SLRs, and features both optical image stabilisation and a ring-type ultrasonic autofocus motor with full-time manual override. Meanwhile the AT-X 12-28 F4 PRO DX is a replacement for the company's existing 12-24mm F4 wideangle zoom for APS-C cameras. But rather than making the lens wider to match its competitors, Tokina has chosen to extend it further into the 'normal' range, to give an 18-42mm equivalent zoom.
Sony has announced it plans to release several firmware updates for A-mount and E-mount systems on February 4, 2013. Updates to Alpha and NEX bodies relate mostly to lenses, including the addition of Dual-AF support for 11 lenses on the A99, and Fast Hybrid AF support for six E-mount lenses on the NEX-5R and NEX-6, among others. Three E-mount lenses also get updates to enable Fast Hybrid AF support. See table below for more detail on which bodies and lenses will get updates.
Canon has announced two additions to its range of Cinema EOS prime lenses, a 14mm T3.1 and 135mm T2.2. The CN-E14mm T3.1 L F and CN-E135mm T2.2 L F are both designed to be used on movie cameras with image sensors up to 35mm full frame in size, and include a range of features optimized for movie shooting. These include geared focus and aperture rings with markings designed to be read from the side of the camera, 11-bladed circular aperture diaphragms, and all-metal weather-resistant construction. The 14mm T3.1 will be available from April 2013 at an estimated retail price of $5,500, while the 135mm T2.2 will appear in May for $5,200.
DxOMark has introduced a new metric of lens sharpness that it's calling the 'Perceptual MegaPixel'. This is designed to give a simple, easily-understandable indication of how a lens impacts on the resolution of the camera with which it's paired. The measurement is based on standard MTF (Modulation Transfer Function) testing, but also takes into account the sensitivity of the human visual system to detail. The data can be explored over at the DxOMark website.
Carl Zeiss has announced its annual photo contest for images shot with one of its lenses. Any Zeiss lens is considered valid, from Nokia smartphones through Sony compacts, such as the RX100, to the company's high-end interchangeable lenses. This year's theme is 'The moment that knows no limits' and first prize is one of the company's manual focus SLR and rangefinder lenses, with a variety of other Zeiss-branded prizes for runners-up. The contest runs on Flickr until January 15th.
Adapter and accessory maker Fotodiox has announced two adapters to enable the use of filters with wide-angle lenses that have large convex front elements. The WonderPana Filter systems are based around adapter hoods that allow 145mm circular filters or 6.6" rectangular filters to be used, via an adapter. Each system comes with a lens cap that mounts on the hood, allowing the lens to be stored and protected without needing to repeatedly remove the adapter hood. A variety of adapter and filter kits are available for a range of Super-wide and Ultra-wide lenses.
We've had our hands on Canon's latest zoom, the EF 24-70mm f/4L IS USM, for a couple of hours and prepared a quick preview. It's clearly designed primarily as a 'kit' lens for the EOS 6D, but of course will work just as well on Canon's other full frame bodies such as the EOS 5D Mark III, as well as APS-C cameras on which it will offer a 38-112mm-equivalent range. In our preview you can read more about the lens and its features, including its unusual macro function, and see how it compares in size to Canon's other L series standard zooms.
Canon has announced two lenses for its EOS system. The EF 24-70mm f/4L IS USM is designed as a relatively compact image-stabilized standard zoom for full frame SLRs, and will be offered as a kit with the EOS 6D. It includes a Macro setting offering an impressive 0.7x magnification, backed up by Canon's Hybrid IS that promises increased effectiveness at close distances. It's also weather-sealed, and will be available from mid-December at an RRP of $1499 / £1499.99 / €1459. Meanwhile the EF 35mm f/2 IS USM features an all-new optical design, and includes image stabilization and an ultrasonic focus motor. It will be in on sale early December for $849.99 / £799.99 / €849. Both lenses will work on full frame and APS-C cameras.
Nikon has announced that it is developing three additional lenses for its 1 System mirrorless cameras. The 32mm f/1.2 will offer a classic short telephoto 'portrait' option, equivalent to an 86mm lens on the 35mm full frame format. The 6.7-13mm f/3.5-5.6 VR is an image-stabilized, 18-35mm-equivalent wideangle zoom. Finally the 10-100mm f/4-5.6 superzoom will offer a similar 27-270mm-equivalent range to Nikon's existing 1 System powerzoom, but in a smaller package with a mechanical zoom ring. Full specifications, price and release date are yet to be revealed.
Sony has announced a series of firmware updates for its cameras and lenses, including the addition of Hybrid-AF compatibility for key E-mount lenses and the option to disable the movie record button on cameras including the NEX-7. The NEX-7 also gets an increase in the range over which you can set exposure bracketing - the ±3EV range it now offers is something a users have been calling for. Firmware v1.01 also promises to improve the responsiveness of post-shot image review. Further updates for the SLT-A37, A57, A65 and A77 also offer the option to disable the movie button and provide lens correction for a broader range of lenses.
Just Posted: Sony E-mount 10-18mm F4, 35mm F1.8 and 16-50mm F3.5-5.6 Power Zoom lens samples on the NEX-6. Our last set of images from the Sony press trip is a series shot with the latest NEX camera and the three E-mount lenses announced at Photokina - the E 10-18mm F4 OSS super-wide-angle zoom, the E 35mm F1.8 OSS fast normal prime, and the E 16-50mm F3.5-5.6 PZ OSS power zoom. We've selected ten images shot with each lens and compiled a combined gallery. Full-size images are, as ever, available for download.
Photokina 2012: Fujifilm has been showing off the way its X-Pro1's hybrid viewfinder will behave when used with zoom lenses - which we demonstrate in a video. It has also moved to quell suggestions that its XF lenses are ready for a full-frame X-mount camera. 'It would not work - XF lenses could not be used with a full-frame sensor,' said Hiroshi Kawahara, operations manager of Fujifilm's product planning division. He also drew our attention to the way X-Pro1 users will be able to use the hybrid viewfinder with zoom lenses - a feature that will be added in a forthcoming firmware update.
Fujifilm has released firmware version 2 for the X-Pro1 mirrorless camera, that it promised before Photokina. The update improves aspects of the camera's operation that we criticised in our review, most notably focusing, both auto and manual. Firmware updates for each of the lenses are also required, and downloadable from Fujifilm's website. We've quickly tested the firmware and seen substantial improvements in both manual focus operation and autofocus speed - indeed we'd recommend all X-Pro1 owners install it. Click through for more details.
Photokina 2012: Samsung has announced two lenses for its NX mirrorless camera system, a 12-24mm F4-5.6 ultra-wideangle zoom and a 45mm F1.8 short telephoto prime. With angles of view equivalent to 18.5-37mm and 69mm respectively, both are billed by Samsung as lightweight and portable, and feature the company's unique i-Function control system. The 45mm also uses a stepper motor for fast and quiet autofocus.
Photokina 2012: Sigma has announced it will brand its lenses in three categories and has introduced a new lens in each of the categories. The 'Contemporary' range will cover compact, flexible zooms, such as the new, smaller 17-70mm F2.8-4 DC OS Macro designed for APS-C DSLRs. The 'Art' range will include lenses such as primes, wide-angles and macros, and a new 35mm F1.4 DG HSM covering a full-frame imaging circle. Finally, the 'Sports' range will encompass Sigma's telephoto primes, telephoto zooms and superzooms, such as the new 120-300mm F2.8 DG OS HSM.
