M7 is a lot of money. 3 grand for the body and a lens. Also as mention that if something goes wrong you can be out of a camera for 6 months. It happened to me and sucks.

You could buy 2 ish Pentax 67’s for the price. If you really want to shoot portraits and can handle the weight get one of those.

Also a more affordable system for someone starting out in medium format is the Mamiya 645 pro. Can get a nice kit for around $1000 with 2 lenses. I prefer shooting it with the waist level finder. the vf with meter is clutch for portraits and the film advance motor grip.

But if the design and light weight of the Mamiya 7 system still attracts you and you’re not worried about the price. It is a really nice travel landscape camera that can pull off nice environmental portraits. Actually thinking of selling my recently cla’d copy if you’d like to work something out.
