D800 vs MF Film, not a standard question

I had the EXACT the same question as you before, and I got Mamiya 7ii and had been using it along with D800e. I do documentary and contemporary art. The reason I choose Mamiya 7 is it is one of the most popular camera for this genre of the photography. I bought D800e because I was not happy with the image quality of my portfolio, which are shot with various digital cameras.

D800e and Mamiya 7 are the completely different animal, although the size and weight is similar. I ended up selling D800e and went back to my little NEX7 (now I'm waiting for Fuji-XE1). I still have Mamiya 7ii, although I still have mixed feeling about it.

What I found using both cameras are:

1. There is probably very little difference between any current digital cameras in terms of IQ. The lens and post processing makes difference. I actually prefer NEX with Zeiss lens to D800 with Nikon 35mm. Carrying super heavy D800 makes no sense to me. It's impossible to me carrying both MAMIYA and D800 (about 5KG including bag) all the time. D800 is a better camera than NEX for AF, metering etc, but NEX doesn't have any problem with its AF and metering 95% of the time in the real world and it's way lighter than D800.

2. The print from Mamiya 7 has the quality that I was looking for. They do look real photography, instead of digital snapshots. They will certainly change the impression of my whole portfolio when I finish replacing all of the pictures.

3. It may sound stupid, but I feel like I'm a real photographer when I shoot with Mamiya. I feel more responsible for what I'm doing.

4. Mamiya is rangefinder, so it's much harder to compose. I'm not rich, so I can't shoot it like a digital camera. I think I have missed many good shots because I'm cheap.

5. Mamiya lens is not bright, so do not expect shallow DOF. If your main concern is shallow DOF, there is NO reason to use film nor MF camera. APS or FF digital camera and Zeiss lens does a great job. Just buy Zeiss lenses for Nikon. They should be excellent.

6. I don't have to explain the difference between the quality of film and digital, because if you can't tell it yourself, there is no reason to use film at all. Stick to digital and you'll be happy.
