p.2 #2 · Developing a tilt/shift system for 35mm digital camera based on 4x5 camrera
Do you run into problems where the camera's lens mount opening block the image circle to the sensor? It seems that this would be very limiting for large shifts and rise.

So far I did not have any architectural photography which may require shifts, only tilt in a studio. So, that was not a problem for me, as lens was staying in front of the sensor during the tilt.
I think it would be a limitation when I'll be shifting the lens, agree with you. However, do not have plans for such use of the setup, did it for in studio use, product and jewelry photography. it's too heavy to go out with (for architecture) anyway:-)

Alex and John, flat out brilliant.
@ Photomaximum: only the size of the image circle. MF lenses have around double the image circle (in both directions) so shifts can still be with the acceptable sharpness area. My understanding is that 35mm lenses may be sharper (in terms of absolute resolving capacity) but the image circles are (except for dedicated 35mm TS lenses) only enough to cover the sensor. And from these I assume that the enlarging lenses have similar large image circles.

I want a setup like this for the D700!!!
Thanks, that's what forums should be about, sharing info.
The reason 'some' enlarging lenses are good for tilt or shift is indeed because of the large image circle but only an enlarging lens designed for a medium or large format film will have a large image circle. If you use an enlarging lens intended for 35mm films, say a nice 50mm or 63mm Nikkor, then I think you'll find it's image circle will not be large at all. The Rodenstock 80 is designed for use with 6x7cm film. It also helps that its an APO lens and has sharpness to spare.
