Camera Lenses: Digital Camera Lenses: Film Camera Lens

Tamron has announced a 24-70mm F2.8 zoom for full frame cameras that features inbuilt optical stabilisation - a first in this class of lens. The SP 24-70mm F/2.8 Di VC USD, to give it its full name, also incorporates an Ultrasonic Silent Drive motor for autofocus, which allows full-time manual focus. The lens is moisture-resistant and features a circular aperture diaphragm for the attractive rendition of background blur. It will be produced in Canon, Nikon and Sony mounts, with price and availability to be confirmed at a later date.

Until recently, LCD was the only technology used for digital camera displays. This is beginning to changes with the emergence of Organic Light Emitting Diode (OLED) technogy. OLED offers a series of advantages over LCDs, particularly for photographers. Whether it's the display panels on the back of the Olympus PEN E-P3 or the microdisplays used as electronic viewfinders in Sony's SLT-A77, OLED is starting to make an impact on the camera market. Ron Mertens, editor-in-chief of OLED-Info, explains some of the advantages and disadvantages of this type of display, and gives an insight into some of the latest developments in this emerging field.

Are High Dynamic Range photos appropriate for illustrating news? That's the debate that's been started by the Washington Post's use of an HDR image on its front page in January. Sean Elliot, president of the National Press Photographers Association came down firmly against it, saying, 'HDR is not appropriate for documentary photojournalism.' John Omvik, Marketing VP with HDR software maker Unified Color understandably disagrees. He's written us a response arguing that what we see is closer to HDR than, say, a mono photo shot with Tri-X film.

Kenko-Tokina will exhibit a mockup of a 70-200mm F4 telephoto zoom that features both a ring-type ultrasonic autofocus motor and optical image stabilization at the CP+ trade show in Japan. The AT-X Pro SD 70-200 F4 (IF) FX will be the company's first stabilized lens, and will likely be especially interesting to Nikon SLR users who currently have no option that's directly comparable to Canon's popular and highly-regarded 70-200mm F4 designs. Further details are limited, but the lens appears to feature both internal zoom and focus mechanisms, and has a usefully-close minimum focus distance of 1m. (via Megapixel.il)

Kenko-Tokina has added the mirrors back into mirrorless with the launch of an ultra-compact Reflex 300mm F6.3 for Micro Four Thirds. This fixed-aperture, manual focus lens revives the catadioptric lens design that was especially popular in the 1970s and '80s for producing small high-magnification telephoto lenses. With a 55mm filter diameter and weight less than 300g, this is possibly the smallest lens of this type that's ever been made for stills cameras. The spec is rounded-off with a minimum focus of 0.8m and 0.5x maximum magnification, making the lens potentially interesting for chasing insects and the like, just as long as you can hold it steadily enough.

Fujifilm USA has announced its recommended pricing for the X-Pro1 high-end mirrorless camera. The MSRP will be $1699 for the body and $599-$649 for the lenses, meaning you can expect it to create around a $2300 dent in your pocket if you want to be able to take pictures with it. Canadian prices will be dollar-for-dollar equivalents. Fujifilm UK meanwhile hasn't yet announced pricing, but one of the country's retailers is taking orders at £1429 for the body and £549-599 for the lenses, which gives a good idea of how much you'll need to scrape together.

Alongside the announcement of the K-01 mirrorless camera, Pentax has updated its K-mount lens roadmap to include planned releases for 2012 and 2013. In a PDF document published on the company's website, it indicates that three lenses will be introduced during the course of this year - a 50mm 'standard' lens, a superzoom in the 18-200mm class, and a super telephoto in the 500-600mm range. Four zooms covering the full wideangle to telephoto range are projected to follow later, alongside a 1.4x teleconverter.  

Pentax has formally announced the K-01 K-mount mirrorless interchangable lens camera and a revised 40mm F2.8 pancake lens to match. Built around a 16MP APS-C sensor, the camera can mount most of the lenses the company has ever made. It features sensor-shift image stabilization, a 920k dot rear LCD and can shoot at up to 6 frames per second. The rather interesting design is the work of respected product designer Marc Newson and features a logo of his signature on the base of the camera. The K-01 (which the company says should be pronounced 'kay-zero-one'), will cost around $749 body-only and $899 with the 'XS' version of the 40mm lens.

Ricoh has released a 24-85mm equivalent F3.5-5.5 zoom module with a 16MP APS-C sensor for its GXR system. The latest camera unit offers a flexible focal length range that starts slightly wider than the average kit zoom, without making the camera excessively large. It's the first GXR module to be built around a 16MP sensor. Announced back in November, it is the first zoom module for the system to offer APS-C image quality. If our suspicions are correct and it uses the excellent Sony 16MP sensor, this promises a lot both in terms of image quality and focus speed (the faster readout of the sensor helps contrast-detection systems to more quickly ascertain correct focus).
