Sigma launches new wide-aperture 50mm HSM lens
Sigma has done a one-up on the other wide-aperture 50mm primes on the market with the announcement last week of its 50mm f/1.4 EX DG HSM.
The company’s latest "fast 50" sports Sigma’s ring-type Hyper Sonic Motor (HSM) focus drive, promising fast, near-silent AF operation and instant manual focus override just by turning the focusing ring. The EX pro-series lens also uses multi-layer coating to control flare and ghosting, and aspherical elements for aberration correction.
Sony’s new full-frame DSLR out in the open at Photo Imaging Expo
Tokyo hosted the Photo Imaging Expo 2008 late last week, and while there hasn’t been a flood of news from the show, apparently Sony’s planned full-frame pro DSLR that we reported on during PMA got a little more solid this week.
The photography blog masterchong.com posted several hands-on photos with the new camera (seen only under glass at PMA), along with shots of a new Sony external flash unit and battery grip to accompany the release. The new model, speculatively called the Alpha A900 and targeted squarely at pro bodies from Canon and Nikon, utilizes a newly developed 24.6 megapixel CMOS sensor.
Reports from PIE have confirmed that we should expect final versions of the A900 to make an appearance in time for Photokina in the fall.
