Film Tested Vintage Mamiya RB67 120 Medium Format Film Camera w 150mm f4 (377)
The vintage Mamiya RB67 120 medium format film camera is built like a tank. RB stands for Rotating Back meaning you can rotate the filmback to landscape or portrait mode to take a picture. And, it weighs as much as a tank. I don't recommend using a strap and hanging it around your neck walking about taking pictures. This camera is a solid workhorse. A truly professional tool. It is completely mechanical so, little to go wrong. This copy is from my personal collection.
It comes with a 150mm f4 lens which from a 6x7 to a 35mm equivalent translates to 75mm f2 when you apply a 50x crop factor. Meaning that it falls in the ideal range of 75-85mm for taking portraits.
The light seals and the mirror damper have been replaced by me. The prism makes composing images a charm. Given the age of the prism, there are black spots on the mirror which is called desilvering - when due to age, the silver behind the mirror surface erodes. It doesn't impact your final image, you do need to be able to focus on your composition despite desilvering - after taking a few shots, you forget it is there.
The camera works well. The lens is clear of any fungus or separation and comes with a clear filter to protect the front element along with a lens cap. Mamiya designed safety features in this camera quite well. For example, unless you remove the dark slide on the film back, you cannot press the shutter to take a picture. Or, it won't let you remove the film back. Buy another film back (I have a 6x4.5 for sale) and now, mid-session, you can switch to a different film. Of course, Mamiya made a variety of lenses for the RB67 everything from wide-angle to telephoto lenses.
I rate the body cosmetically as a 7.5/10 due to minor spots of paint loss and some of the leatherette beginning to come unglued. I rate the prism finder cosmetically as a 7/10 due to the condition mentioned above. Both, the camera + lens and the prism - I rate as 10/10 for functionality. I would suggest investing in a new viewing or focusing screen depending on what you intend to use the camera for. The current screen is suitable for general photography. If you intend to do landscape or architectural photography, I would suggest investing in a grid screen with a split screen. Let me know if you would like for me to source one for you. I also have the special cable release that I am selling separately - it is a two-pronged release cable made by Mamiya that lifts the mirror up and then releases the shutter so as to minimize any vibration for razor-sharp shots.
Mamiya makes their cameras with fine craftsmanship. Mostly made of metal. See attached photographs taken with it. When you buy an RB67, you are not buying a camera, you are investing in a system meaning that it has a wide selection of options available to suit your photography needs from lenses to grips to film back, etc.
