I own a Yashica D. While I do like it, am I curious to see if there is other medium format cameras that can produce sharper images.
Yes and no.
I cannot comment on the Yashica as I never owned one. I am relatively new to medium format photography, but I am lucky enough to own two MF cameras that offer (supposedly) one of the sharpest optics in town: the Fuji GF670 and a Hasselblad V-system with three Zeiss lenses, and here's my confession:
While I observed some increase in available resolution, I cannot say the increase was as noticeable as I hoped. When compared to 35mm, the difference in resolution is not even close to the difference in
negative area.
I've looked closer into it and the reasons appear to be:
- Lenses. The best 35mm lenses deliver more absolute resolution than the best medium format lenses. A stopped-down Summicron beats a stopped-down Zeiss CF partially negating the negative size advantage.
- Shake&motion blur. If you want more resolution, your camera needs to be more steady. This rule is universal across formats, and this is why high-res digital cameras frequently disappoint their owners. My Hasselblad can deliver stunning detail on a tripod, but in a real-life hand-held situation around 1/125s to 1/250s it's not that much ahead of a Leica.
So I stopped caring about resolution, as I never print anyway. The reason I shoot medium format is what many people here call "tonality". It's a strange term which doesn't get much attention, but it comes down to compressing more light into a finite viewing area, be it a print or a scanned image.
My prediction is that you will not find any satisfaction of spending more to "upgrade" your Yashica. You are already getting 95% of medium format benefits.
