MAMIYA PRESS LENSES:
Versatile, Mamiya offered a wide array of lenses that can be used with Mamiya Press cameras, and of course, that includes the Universal. I have what I believe to be the core offering of these lenses. Due to their age though, I'm not aware of any that are multi-coated. But for film, I photograph in black and white, and I regard single-coated lenses as an advantage.
A bit of a negative, Mamiya Press focusing mechanism has it's limits as to how close one can be and still obtain accurate focus. One can find tables with these limits in the Mamiya Press instruction manual.
Most Mamiya Press cameras, including the Universal, have integrated parallax corrected frame lines in the view finder. A lever just to the left of the viewfinder toggles between these frame lines for 100mm, 150mm, and the 250mm f5 lenses.
>> 100MM F2.8: This is truly an outstanding lens. Very sharp, and fast. Can offer good bokeh. (See 1st Photo above.). I think that a standard lens sold with Mamiya Press cameras was the widely available 100mm f3.5 lens.
>> 150MM F5.6: Though not known to be particularly outstanding (like the 100mm f2.8), the Mamiya Press 150mm f5.6 lenses are decent in this focal length. I have a "blue dot" version, which I think are sharper and more recent than non blu-dot versions. I know that "blue-dot" lenses were made for Mamiya twin lens cameras. (Photo soon.)
>> 250MM F5.0: This is a huge lens that integrated with the viewfinder system. It has it's own rotating cradle, which itself, can be attached a tripod or monopod. This is one of the fastest lenses available for any medium format camera. (See 1st Photo.)
There's also an f8 version in the 250 mm focal length; but, it does not integrate with the viewfinders internal framing system. Perhaps the f8 maximum aperture doesn't provide sufficient light for accurate focusing?
>> 65MM F6.8: Principle wide-field lens for the Mamiya Press system. My example of this lens was brand new in the box. (See 2nd Photo.)
>> 50MM F6.3: Another outstanding lens known for it's sharpness and rectilinear qualities, this lens was patterned after a Biogon design. (Similar to the RB56 50mm lens.) This lens is a very effective lens, when paired with a Mamiya Press camera a the 6x9 Mamiya Press film holder. The lens covers 6x9 as one would expect, and given that Mamiya Press film holders are known to hold film especially flat, this is a respected lens/camera combination for quasi-super wide photography. (Photo to follow.)
Attaching these lenses to the body is a two step process. Similar to the RB67 cameras, one attaches the lens in the correct orientation, and then twists a rim to anchor the lens to the body. This rim is easily seen in the 2nd photo below. The second step is to attach the shutter release cable. Should one need to quickly alternate between two lenses, they'd be best served by purchasing a second body. Fortunately, bodies for this camera system are inexpensive.
