Belated congratulations on your Mamiya purchase. The camera seems to be working out very nicely for you. Great photos! I believe your camera has a rotating back. Was that one of the features that attracted you to this camera? I'm interested in getting back into medium format, but I really don't know all the camera models available (used, of course) that have this feature. Do you have any insight from your pre-purchase investigation concerning medium format models available with rotating backs? Thanks to you and to anyone else who can lend me a hand with this!

I have a Mamiya RZ Pro II. The revolving back is nice but the bellows focusing is the schnitz!

Brooks, I've got a quick question for you, but I'd appreciate a response from anyone listening in: A seller told me it's possible to run 120 film through an RB67 220 back. What do you think of that claim? Thanks!

I think Brooks should chime in on this in case I am incorrect.

I have run 120 film through my 220 back with good results. Theoritically speaking, however, there could be a differential in pressure plate pressure and in the winding mechanism due to the differences in the thickness between the two kinds of film. The backing paper and and film combination is thicker on the 120 films than on the single layer of film in the 220 types- the leader paper only kicks in at the beginning and end of the roll . When using the 120 film in the 220 back I used to fined more tension on the winding levers when winding the film in and out as the tape passed through the guide rollers in the back.

I know that in Rollei camera the 120/220 compatible models had 2 different pressure plat position- one for each of the sizes. I wonder if using the 120 film in the 220 back can compromise the focus, the winding mechanisms or the safety of the film itself do to the possibility of scratching under excessive pressure. I have experience some scratching from the spring loaded rollers (THE CHROME ONES) if the tiny rollers come off and the sharp edges of the spring loaded guides came in contact with the film.

Although the backing paper on 120 films is not all that thick, when wide angle lenses are used, the flange-focus distances can be very critical and a few millimeters off can cause focus problems. I also remember that years ago Kodak film that were Manufactured in Europe had thicker backing papers than the American versions and were know to foul up winding mechanisms- that was long ago- I am old.

I must admit that my Mamiya 67 camera have given me great un-interrupted service for over 30 years- the earlier models, the RBs. are built like brick outhouses and the RZs cane be a but more delicate but don't drop either model on your foot- RZ with a prism, a winder and a digital back weigh a ton. The only this that nearly disintegrated beyond repair were my backs- I must have abused the heck out of them.

In this case my safe advice would be to have separate backs for the different film types. It is a case of do what I say not do what I did! Brooks will relate to this modest philosophy.

Yes, congratulations on the purchase of a fine medium format camera. I have a RZ, but the quality of the lenses is the same. Very high quality of glass. As for film, that depends on the lighting you will work with. Personally, I like Ilford Delta 100, but have shot all different kinds. Recomend to choose several (Fuji Acros B&W, Ilford Delta, Kodak, Efke, etc). until tou find one that you really love. A photo friend says the film "should kiss the subjects".
