Mornin' folks!
I'm hoping to start using my M42 bellows with slide copier to digitize my 35mm film negatives.
I'm using my K-70 with an M42 adapter, connected to the bellows and slide copier.
My problem is with the lenses I currently have, the magnification is too great - that is, I can't back up enough to get the whole negative in the frame. The resulting digitizing is substantially cropped.
Therefore, I need a lens that produces a lower magnification.
One that allows me to use my APS-C camera to capture a full frame 35mm film negative.
My problems come around when considering the crop-factor... I've never really good at considering 'equivalencies'
I'm guessing a Super-Takumar 55mm f/1.8 may suit my needs (spec sheet attached).
With the 1.5x crop factor, I'd need to have an equivalent coverage of 36mm x 54mm, no?
Since this lens has a lowest magnification is 0.66, that would equal 37mm x 55mm area.
Meaning I'd have more than enough room to capture the full negative..
May someone please double-check my reasoning?
Thanks in advance!
