The new updates bring the Ricoh GXR body as well as both the GR LENS A12 50mm F2.5 MACRO and RICOH LENS S10 24-72 mm F2.5-4.4 VC camera modules up to firmware version 1.07.
For both modules, Ricoh has improved autoexposure accuracy when using the GXR's autoexposure lock feature. Two bugs have also been corrected - the first whereby long exposure images shot in Raw mode were sometimes corrupted, and the second where image EXIF headers incorrectly showed the wrong value for sharpness.
In addition, there are several changes specific to the GR LENS A12 50mm F2.5 MACRO camera module. A new AF speed function allows selection of either Quick AF (QK-AF) or Framing AF (FR-AF). In the former mode, focusing speed is improved by temporarily pausing the live view display during AF operation. The latter mode keeps the live view display running, but with AF speed identical to that of cameras running the previous v1.06 firmware. The new Quick AF mode is only available when the digital zoom and AF target shift functions aren't in use. Ricoh has also improved Program mode white balance in low light conditions, and focus accuracy when using Full Press Snap with the A12 camera module.
There's only one change specific to the RICOH LENS S10 24-72 mm F2.5-4.4 VC, according to Ricoh's release notes. Focus accuracy is said to have been improved when using the GXR's Auto macro function.
