The collapsable lens mount is really great. The 50mm is about a 27mm on 35mm, the 75mm about 40mm, and the 150mm is 80mm. Meyer The Mamiya 6 is a great camera-I owned 2.

It had the unfortunate luck to be launched just in time for the world to switch to digital so it never really caught on.Yamanobori> Thanks for that, I had a feeling there would be a straight forward mathematical relation. It is sometimes referred to as the 'camera everyone forgot.' If you think of the time range I just gave you, you can see why. Although the Rollei has a similar build quality to the M6, the RF645.The Bronica rf645 is a modern rangefinder that was made from 2000 to 2005. I own the RF, a Leica M6 and a Rollei TLR. 43mm x 0.9375 = 40mm.I would like to suggest the Bronica RF645.

It also seems there is a general consensus that the Mamiya 6 or 7 is a brilliant camera.For myself, I really enjoy film and am focusing entirely on black and white at the moment. You guys are definitely right about them holding value. How to Shoot Film - Ken Rockwell.I am really doing the typical plan for your next purchase sort of thing, even though I am a beginner and a few years away from the thousands of dollars a Mamiya set-up would seem to be demanding.

That guys work is brilliant to the point of making a comparison between Pentax 67II performance and Mamiya performance a moot point. I have little interest in shooting people or studio work.The Mamiya 6 or 7 seems to fit the bill nicely, but is there a Pentax medium-format that has the same portability and low(er) weight? Are the Pentax lenses for medium format of comparable quality?Tuco> You bring up an excellent point there, in my musings I had not thought to consider the tripod.Phonoline> I checked out the link you posted. I occasionally go backpacking, so I will be taking my new hobby with me. Also, I enjoy landscapes, cityscapes and architecture. As such digital is not really my thing.

If you are a control freak, and I mean that in the nicest sense, you may find a rangefinder a little too loose and goosey.I have always used a handheld meter with the Mamiya 6. Rangefinder and viewfinder framing is not as accurate as an SLR, but I found the Mamiya 6 viewfinder very good. It is not bad and you get used to compensating for it. The minimum focus distance with the 150mm is 1.5m and the 210mm on the 7 is a little over 2m.Yes, because the viewfinder and lens are on a optical axis, you get parallax. For now I really appreciate all of the opinions and experiences you all have shared with me.If you don't mind me posing just a couple more questions to this thread:Am I correct in assuming that Rangefinders induce effectively no 'shake' at the time the shutter is released, due to the lack of a moving mirror?The reference to close focus and rangefinders: Is this indicating that as you get closer to the subject the parallax becomes more pronounced? This I'm presuming is due to a growing difference between the 'angle of incidence with the lens' and the 'angle of incidence with the prism'? How bad is it in your experience?DaveThe minimum focus distance with the Mamiya 6 75mm and 50mm is 1m, which is consistent with the normal and short lenses. In about two years I will have to re-evaluate price and budget and make a final decision then.

But I have also had a great deal of experience with separate light meters as I started using them in 1984-the same one in fact, a Gossen Luna Pro SBC.
