I'm trying to get my head around magnification factors using a bellows and either a Schneider 80mm or 120mm macro lens. This is all new to me, and I'm not sure I understand everything. Google is not my friend in this instance...as crawling the internet has only got me more confused.
Here's my question. Using a camera at its maximum bellows extension of 250mm, what would be the largest magnification factor I could expect of the subject on the film/sensor plane with each lens?
My rudimentary numerical skills have come up with 2.08:1 for the 120mm and 3.125:1 for the 80mm.
Am I close?
Thanks in advance, and pass the tylenol.
