Sony has recently published an updated firmware for the DSLR-A700 camera.

Changes since oldest v3 firmware are:

  • The choice to select auto exposure bracketing (single & continuous) with 3 shots in 2 EV steps has been added.
  • The choice to turn [Off] the High ISO NR feature has been added.
  • Improvement of the image quality in high ISO setting.
  • Improvement of the auto white balance and D-Range Optimizer performance.
  • Improvement of reliability for communication between camera body and vertical grip.

Though I haven’t yet tested the improvements of the image quality using high sensibility or D-Range Optimizer, I mostly appreciate the possibility to make 3 shots at +/-2EV in auto-bracketing, which eases creation of HDR or exposure-blended images.

Note that upgrading the firmware resets the counter for file naming.
