OPINION: I’ve used this camera, and personally I love it.If you can get a maxwell screen upgrade from bill, this camera will perform very solidly. CON: The Camiya viewfinder can be just as bad as the Contax 645, thats minus the upgrade.The parts you will be able to find in abundance online, so it shouldn’t be a problem. It’s a great entry priced medium format camera with a solidly beautiful lens that many can say rival the Contax 645. PRO: The Mamiya system has quite a few advantages, and one of the main benefits of the Mamiya comes simply from the cost.I believe that is one of the main benefits i would use this camera for, would be indoor photos and moving shots. This actually makes me wonder why i sold mines in the first place. I’ve successfully used these photos in moving ceremony shots & many indoor photos with great success. OPINION: This is such a solid system, from the build down to the photos.If cost is not a issue for you than by all means jump into a Hasselblad, but with the ranging cost of each lens you can easily purchase a Contax 645 plus more. (50mm Equivalent 70mm) which will be considered a portrait lens. Compared to the other two systems listed above, the lowest aperture lens you will find on a Hasselblad will be a F2.2, which will be a 110mm F2.2 Lens. CON: Being that the Hasselblad is a newer system compared to the other models, you will be looking at a higher cost to purchase the lens and upgrades.PRO: It has numerous advantages, bright viewfinder, newer frame work, rapid and accurate auto focus, rechargeable hand grip batteries and last but not least the leaf shutter lens that allows you to shoot at low shutter speeds.However i will point out a few benefits as i’ve had this same discussion with one of my attendees at a workshop before. Ultimately what your medium of choice in what you choose to photograph your subject is entirely up to you. Hasselblad H1 vs Mamiya 645 vs Contax 645
