June 2009 news and reviews
Adobe has updated its DNG digital negative specification to allow a series of image corrections to be embedded in the file. Version 1.3 of the non-proprietary RAW file format allows a series of 'corrections and enhancements', which Adobe is calling opcodes, to be defined in DNG files. These opcodes include the ability to specify corrections for lens aberrations such as geometric distortion and lateral chromatic aberration that should be made to the RAW data when it's processed.
Just posted! Our lens review of the Nikon AF-S Nikkor 50mm F1.4G. This version replaces the AF-Nikkor 50mm F1.4D we reviewed last year, bringing entirely new optics and a built-in AF-S motor which allows autofocus on all of Nikon's DSLRs. On its introduction Nikon hailed it as 'redefining the standard lens concept', so how well does it live up to these lofty claims?
Cosina has announced a Voigtländer branded Nokton 50mm F1.1 high speed lens for the Leica M mount, in a launch which marks the 10th anniversary of Cosina's Bessa series of rangefinder cameras. The Nokton becomes the second-fastest lens currently available for the M mount after the Leica Noctilux 50mm f/0.95, yet despite its speed weighs in at a relatively manageable 15 ounces and uses 58mm filters. The lens is constructed with 7 elements in 6 group and has minimum focusing distance of 1m. It will start shipping from the end of this month at a retail price of approximately 130,000 yen.
