More re Crops

Hello ozdean

That is an interesting test !

Your test may show that the metering react on the crop mode.

I checked my K5 once how (for the flash pictures) the matrix metering react on a mini light spots. The 77x segment matrix of the K5 do not cover the boarders. So in a test a mini light spot at the boarders do not get involved into the matrix metering.

In your case of the crop mode: why should the K3 III meter in regions, which get not into the picture. Maybe the K3 III do therefore let it's RGB sensor metering use always only the crop area than. You can try this out very easy with a mini pocked lamp (but please not with a super bright pocked lamp), the camera in M mode and watch the bar graph when your mini lamp is in the crop area and when it is outside.

But, because the crop can redone in the DCU, when it is a RAW file, the camera captured always the fully sensor pixels, only the jpg get the crop when saved in the camera.

BTW: When I use the crop or square mode with my K1 and I use RAW, I can not use the camera's picture editor for to get the FF format back. I can do this only in the DCU. Can the K3 III do this in it's picture editor ?

BTW II: I think the different crop modes would be good for the K1, K1II too, for non FF lens . Some you should use only with an APS-C crop, with others you can use a 1.3x crop, because the boarders still would looks good enough in this 1.3x crop. And for an easy use, you see the 1.3x crop frame in the OVF.
