Yes. speaking from a personal level, I always beleived the old adage that you have to make enlargements to see the difference between 35mm and 120 format.
I beleived it, but I skipped a step, and went right to 4x5 inch negatives where the diffence is indisputable.
I beleived it, until I got into this semester, where we have to use 120 roll film in black and white.
Not 4x5, not 35mm, 120 only.
Well....I didn't have to get to the enlarger, I can see the difference in the contact sheets. I thought it must be because of the size difference, so I made some 5x7 prints and still....quite a difference.
I shoot prime lenses in 35mm and at fairly small apertures and I use very slow film, efke 25 and 50. So I know it's not sharpness that's improving.
It's something else. Not sharpness.....maybe it's tonal range or something... I don't know what it is, but I bought a Seagull 109 for 200 bucks thinking it was just a cheap throwaway camera that I was going to sell for 50 bucks once the semester was over.....
But what do you know???....It actually takes substantially better pictures than my 35 mm, so I've started using it for when I go out with friends and I wanna take snapshots for the occasion in low light situations, but still have them look nice...
I don't think I'm going to sell my seagull. Besides, someone else would just break it in the first week anyways. It has this quirk where if you change the shutter speed while the shutter is cocked....it breaks the shutter, not always the first time, but eventually.
