Hi All, I shot a bit of 35mm a few years ago in college and have since been shooting exclusively digital for work and other things since then. I recently picked up a Mamiya 645 Pro to try my hand at MF film and do something new. I got my first few rolls back from the lab the other day and after looking at my prints I've noticed a few things I wanted to ask other shooters about. -I noticed that a lot of my photos were soft or the focus was not where I remember focusing when I made the image. I'm familiar with focusing on a split focusing screen and I remember focusing so that the two halves of the image matched up. Is the DOF shallower on MF because the imaging area is so much larger? Is there a trick to focusing I haven't picked up yet? Let me know if there is any other info I can provide! Thanks!
