I am a new Sony user, but not new to photography. The new A7r2 replaces my Nikon D810 out fit mainly becasue of weight /size, and the ability to use legacy lenses of which I have a fair collection. My concer is that when I use focus peeking and magnified image, I an niot getting images from my Olympus OM 300mm f4.5 lens that are crisp and sharp. My questionis as follows. I thought using these aids on the A7 that I was using the actual plane of the sensor to acheive focus and that calibration i not needed. Is this correct? And if so, then must be something I am doing and I am having diffculty sorting it out. I also thought using a Ultra Wide lens like th eTokina (Nik mt) and stopping down to f8nwould yield nice crisp shots. It is not doing so, at least to my satisfaction because wwith this lens, the peeking (yellow) is very difficult to see. Again is it helens, me or a issue with the camera? The attached image shot with the 300mm OM lens looked sharp when I was taking it, but is far from that as i look at it now on screen. EXIF show 1/60 sec exposure, Iso 100. I should add that I was using a monopod stabalized against the window and the floor (two solid points) and I had the vibration correction (Sony name for it in body was ON) I would appriciate any thoughts or suggestions concerning this concern of mine from some of more experienced Sony camera users?
