This camera is far more uncommon than the Rolleiflex but prices are modest in comparison and in my humble opinion, a good value. It may be the only TLR that is in the 'ideal 6X7' format. To me, it takes care of one of the major short comings of all other TLR, that is, you can't change mid roll. I Believe that it is unique when compared to other TLR's in that it is the only TLR that allows you to change both the lenses and film backs. It allow you to visualize the depth of field rather than estimate. (faster than the Telerollei at f4.0 and the Mamiya twin at f4.5) The 135mm lens has a diaphragm just like the Mamiya TLR 135mm DS lens that commands a huge premium over the regular version. The 135mm is a super-fast f3.5 lens with great bokeh. With the 135mm lens it probably weighs more than 10 pounds. I came across this post on Photonet some time ago that indicated that the Omegaflex M camera and lenses compared favorably with the Rolleiflex so I decided to add it to my collection. Thanks for your offers but these are quite hard to come by and it took me several years of searching to find them so I'm not interested in selling them for less than I paid.) Numerous requests have poured in from around the world to purchase my Omegaflex M, lenses, and finders. (Since I allowed a few photography blogs to use my photo of the Omegaflex M and it seems like its gone viral. The 58mm and 135mm are my favorite lenses for this camera. And it had problems, shutter speeds were off. Just saw that one of the lenses for this camera sold for over $511 It was the 58mm. Koni-Omegaflex M 6x7 with 135mm lens and reflex finder
