A free firmware upgrade refines shooting responses and creative
options with the α900 and α850 35mm full-frame DSLR
cameras by Sony.
Sony advises all new and existing customers 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
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 eadroom 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.
