DXO  do not look at real life results. Their measuerments have virtually nothing to do with  the results you can achieve with a particular camera or lens. Better ignore them.

The B&H "dynamic range" images are nonsensical, they only show a difference in used tonal curve (lower contrast on the S). Did not bother to read more of the dribble on that page after that.

Maybe, but B+H didn't even crop the pictures the same, didn't say how they processed the files, and claimed that the camera had a great deal of influence on the vignetting of the picture (without explanation????). 

 

Right now I'd trust DxOMark until B+H proves itself...

Hi

 

I have Sony A7r and i can not solve simple problem.

 

Focusing

 

When using E mount lenses is ok.

 

When using A mount any kind of lens via adapter LA-EA4, when camera is just turned on, and no shutter pressed lens is still fousing when camera moves. I work in Manual mode and AF-S (single shot)

so focusing should be working only when shutter button pressed.

When object selected and focused (green square) by slightly pressed shutter button = focusing do not move more, but in preview it goes like in circus

 

Greetings

noone knows?
