if my 400 5.6 was dead on with the Mark IV (1.3 crop) does that necessarily mean that I would need to micro adjust it on the 5d III??

Jul 28, 2012 11:20 | #3 Is the distance from first element to the sensor different with a FF? That's really my question. I nailed some shots this morning of a young hawk but they seem a tiny bit softer then with the Mark IV. Not much,, but a little. This is my first FF body. I'll post some sample shots shortly. _______________

No, the distance between the lens and the sensor is controlled by the focal length of the lens. If you have for instance a 50mm lens and fit it either to a crop body or a FF body then it will be have to be the same distance from the sensor in order to focus.

Jul 28, 2012 11:50 | #6 Thanks for info. As I said this is my first FF and it's still new so I'm getting used to it. I've noticed some of the heavy crops look more like my 1D II did for some reason. I assumed with so many pixels the detail would be mind blowing. I'm not knocking this body in any way. It's amazing so far. Just pointing out some of my observations. Could just be a nut loose behind the viewfinder.

That would resolve any slight focus mis-calibration. It doesn't appear there's much, from your sample images. Alan Myers
