Oh well, there's probably a good explanation..

I would think because the ground glass focus plane is the same as the sensor plane when using lenses 70mm and below which do not have the spacerWhen you use the short barrel of lenses 90mm and above and have the spacer on the back (to have the correct distance due to the longer lenses) the sensor is set back from the focus plane of the GG. hence the focus on the ground glass is not the same as the capture.The use of short barrel lenses is allow the T/S movements and also avoid vignetting on rise / shift So you move the capture plane further away from the exit pupil, so more less you are not shooting down a tube. If no movements then a long barrel would be fine, and the focus plane and capture plane are identicalSo you are correct - you can use short barrel lenses, but it would be like there was no GG option.lets see if and tech guys confirm this :chug:Phil
