Mamiya

Advantages High quality images suitable for dramatic enlargements, well made camera and a pleasure to use.
Disadvantages Could be difficult to use for a complete novice. Expensive though worth every penny.

...This a beautiful camera and I love the quality of images it can take. It is a medium format range finder camera that is as light as many 35mm cameras so you can literally carry it all day without fatigue. Medium format cameras are usually bulky and feel as heavy as a brick ( or a couple of bricks!). As it is light you can handhold it to take pictures. Again most other medium format cameras would make your arms ache or shake too much and you would have to use a tripod. So this camera offers you a choice. You can hand hold this camera all day without having to use a tripod and yet still get high quality medium format pictures or if you want to explore your photography and the cameras capabilities further with a tripod you can. I also own one of the heavier medium format cameras the Mamiya RZ and I've only taken it out for the day... Read review

Advantages large negative size,quality enlargemts, rotating film back
Disadvantages only 10 shots on a roll of 120, heavy camera to use initialy

...The Mamiya RB-67 is an excellent piece of photographic hardware. When I was window shopping for a medium format system to upgrade to I was concentrating on the Bronica systems , Namely the SQ and GS1. Until that is I had a play with an RB-67. Its not a light camera, infact its quite heavy at first, but one soon gerts used to the weight, It is the same basic layout at as other medium format cameras , Interchangeable lens,body,waist level finder & interchangeable film backs. But what makes the RB outshine others is that the film back can be rotated 90' so you can switch from landscape to portrait format without moving the camera, which is very useful at times. It is a sturdy camera, built to last & take a beating,I ve used mine in a studio to on top some of south wales highest peaks without a failure to work ever. The camera... Read review

Advantages Quality, solidity
Disadvantages Weight, evil ergonomics

...Mamiya RB67 When I decided to buy a medium format camera, I looked at an RB67, and easily dismissed it. You need hands the size of a gorilla, and it really ought to be sold with a Benbo tripod welded to the bottom. A kind friend lent me her “new” RB over Christmas - £250, and a lot of black paint missing. I still won’t be buying one: it is a camera I respect, but I certainly don’t love it! But if you want (or need) the versatility of bellows focussing, you may buy one. If you need a camera engineered like a battleship (and every bit as user-friendly), you may buy one. If you want excellent results, and don’t mind ergonomics that are just right for an octopus, you may buy one. If you take landscapes or portraits professionally, there’s a good chance you already own one. An RB67 offers enormous scope for doing things wrong... Read review
