There has been some talk about using 35mm lens on 33x44 sensor camera.

So, without getting into the technical stuffs. Here are my few questions:

1> Image Circle is bigger when focus point is closer?

Yes, but at normal focus distances, there is not much increased size in the image circle, but generally it will depend on the lens design and how much over size the image circle was designed to be... if it was oversized at all.

Thanks

I've heard Leica R tend to have larger image circles.

I don't have any AF lenses, so if I want a picture, I have to do more than squeeze a button.
