Camera scanning with full frame or medium format

[pkr1979]

Hi all,

I'm considering switching from scanners to digital cameras for scanning. So I was wondering if anyone has any experience in scanning with both full frame and medium format, and can say anything about potential benefits with medium format over full frame (or FF over MF).

More specifically I am considering either a used Panasonic S1R or a used Fuji GFX 100s (however, I am open for suggestions). I am scanning small format, medium format (645+67) and 8x10" large format. I am scanning roll film more often than sheet film.

So, comparing one to one I suspect that the Fuji will outperform the Panasonic due to the fact that it has a larger sensor, more pixels, and a higher bit depth, but factors I assume could make a difference as well is pixel shift and in camera stitching.

I know that both have pixel shift, but if I am not mistaken the Panasonic does this in house meaning you get a raw file from the camera, while from the Fuji you will end up with a tiff from the fuji software?

And if you camera stitch - will this not close the pixel gap between these two cameras? I was also wondering how important lens profiles are when stitching, as I am considering the Pentax 645 120mm in combination with the GFX.

I guess my question is can stitching, pixel shift, native 1:1 macro lenses and lens profiles narrow the gap between FF and MF - or even switch it in favour for the FF?

Cheers
Peter

Neither of the digital cameras you mention are medium for at though, are they? What does the 'medium format' in the thread title refer to?

The Panasonic S1R is full frame and the Fuji GFX 100s is medium format. Medium format in the title refers to digital medium format cameras.

Sorry, I didnt realize that the Fuji is MF, silly of me! Disregard my earlier comment.

I'd say, depending on specifics, yes. Especially w.r.t. the lens used.
I'd also take into account performance aspects that may not directly related to pixels - think of field curvature, distortion pattern, vignetting and color variations across the field of view.
