BC, correct me if I'm wrong, but IIRC OVF focusing screens don't actually give you actual DOF ?

 

 

What matters is how the camera shows the scene. I prefer my camera to show the scene like it is, so I can do my own creative decisions based on what one sees. An EVF shows the scene based on the decisions of the camera manufacturer. 

OVF gives the exposure in the metering bar. Over/under exposure is for the photographer to determine.

Huh? My OVF gives excellent DOF preview, and the 3D quality an EVF never gives...

My OVF gives me the scene as it is. An EVF shows the scene interpretation of the camera. Not good for a creative person.

The A7r seems to do just fine with shutter induced vibrations (if one goes by some early user accounts). As do some  MFT cameras with shutter induced vibrations linked with the IBIS. 

 

Now my handheld photography of course never is hindered by mirror slap. If I do things on a tripod, yes, indeed there is never a problem with mirror lock up...
