I know this spans large and small sensor and there aren't a lot of users but improvements to focus were important. Today a big firmware update was announced.

Here are some highlights


Enhanced functions:

Addition of “Screen Magnification Position Movement” when shooting
The magnification position of the shooting screen display can now be moved together with the AF/AE target movement or macro target movement. Supported in both auto focus and manual focus modes. (Macro target movement is only supported on units equipped with macro mode.)

Addition of 3 handy magnification ratios for the focus check function
You can select the magnification ratio from 2:1, 4:1, and 8:1 in the shooting screen. Additionally, you can register the magnification function to the Fn1 or Fn2 key.

Addition of “spot AF, macro AF area selection”
You can choose from normal or pinpoint AF area size when Spot AF is selected or when shooting in macro mode. (Only spot AF is available when GR LENS A12 50mm F2.5 MACRO or GR LENS A12 28mm F2.5 is used.)

Addition of “ADJ key and Fn key registration function” when changing the aspect ratio

You can now register the aspect ratio change function to the ADJ, Fn1 and Fn2 keys.

Addition of “key custom setting initialization” function
Key custom settings can be returned to their initial values.

Addition of “My Setting delete” function
You can return the registered settings in the My Settings BOX and mode dial to the initial values.

Addition of “Shutter half-press confirm” function in the DIRECT screen
You can confirm setting changes in the DIRECT screen by half-pressing the shutter.

Exif2.3 support
Exif2.3 is now supported.

Addition of “Noise Reduction AUTO”
You can now automatically adjust the noise reduction effects on the camera using the AUTO function.

Macro AF Distance Limitation
When macro shooting using the GR LENS A12 50mm F2.5 MACRO, you can now select the shooting distance (distance within which the auto focus can focus) from 7-14cm or 12-30cm to provide overlapping distance ranges.

AF Acceleration
The autofocus control drive system has been improved and accelerated. In association with this change, the AF mode (QK-AF and FR-AF selection mode) in the set up menu has been deleted. (When GR LENS A12 50mm F2.5 MACRO is used).
