Sony has announced function enhancing firmware updates for its DSLR-A900 and DSLR-A850 full-frame cameras. The latest versions for both cameras promise faster AF and broaden both exposure compensation range (to -/+5 from the current -/+3) and the exposure bracketing range (from up to -/+2EV to a maximum of -/+3EV).

Press Release:

Sony announces free DSLR-A900/A850 firmware upgrade Creative shooting enhancements for full-frame α cameras

December 2, 2010: A free firmware upgrade refines shooting responses and creative options with the α900 and α850 35mm full-frame DSLR cameras by Sony.

All new and existing customers are advised to install the upgrade that’s available for download from the ‘Support’ area of the Sony web site.

Autofocus is quicker and more responsive than ever, thanks to improved AF motor control and smarter distance detection of out-of-focus objects.

Creative options are extended by a broadened range of exposure value (EV) compensation settings, now increased from ±3EV to ±5EV. Selected compensation value is displayed in the navigation display on the main LCD screen of both cameras. This boosted EV compensation range gives extra   
headroom when composing extremely high- or low-key images.

Exposure bracketing range has also been increased from a maximum of 4.0EV (three shots at -2EV, 0EV, +2EV) to a maximum of 6.0EV (-3EV, 0EV, +3EV). This wider range gives added flexibility when capturing multiple frames at different exposure values – for example when acquiring images for the creation of powerful post-shooting HDR effects.

As a further refinement, a new menu option allows shutter release to be enabled, even when the camera body doesn’t detect an attached lens. It’s useful for specialist applications such as astrophotography when the camera is attached to a telescope.

The latest firmware upgrade by Sony for registered α900 and α850 DSLR customers is available free of charge from http://support.sony-europe.com/dime/DSLR/dslr.aspx.
