the pics attached sideways but the idea is the same, appox. 1" of rise/ 1" of fall with the 65mm nikkor f4 focused at infinity.
ALSO, if you plan on doing any infrared work, the chamonix bellows I had on my 45n-1 weren't IR proof. I haven't tested the universal bellows on my 45n-2 yet. The shen hao bellows (regular and bag) were IR proof though.
