The biggest news is of course the official announcement of the M-Mount module. That is discussion for another time. For now they are tempting users, or rewarding early adopters for their patience.
I think the biggest highlight is the following
The dismal focusing ability the GXR APS-C modules had in the early stages are virtually gone since the last few firmware updates. But it still cannot compare with dSLR in terms of speed and precision.
While the LCD screen is brilliant, focusing is still a bit of hit and miss at times especially with closeups. It is quite difficult to assess the point of focus accurately and I always hated the magnified view which only shows a small rectangle of highly pixelated image.
Now it comes with FULL screen magnification at full resolution. It is really much much clearer. The only problem is I lose track of the composition. Something easily solved with practice.
Catching up with video cameras, now they have focus peaking in 2 modes. In Mode 1, you see the full color image with the focused portion showing a glimmering outline. Mode 2 the image turns into a grey monochrome with glimmering edges in the focused zone.
It is an amazing tool in view of the relatively large apertures of the APS-C modules. The fly-by wire manual focusing is not precise or fast, but it is enough to get as close as possible. The limit to the focus assist function is in low contrast situation, especially with the A12 28mm. I still get some out of focus pictures when I thought it looked ok on screen.
This is of course a prelude to the long awaited M-Mount module where manual focusing is the only option. Still it is amazing that they updated for ALL the modules.
