<p>I'm curious about this adapter. Is there any use for it on a Mamiya Press camera, or is it designed only for using a Mamiya Press back in vertical orientation on an RB system?</p> <p>Given the placement of the viewfinder on a Mamiya Press camera, using it on one of these cameras wouldn't work. The film holder would interfere with the viewfinder.</p>

<p>Thanks. I'm aware of this site, and it has some excellent information. But, it doesn't state whether the "P" adapters rotate between portrait and landscape orientations.</p> <p> </p>

<p>It's possible to put a "P" adapter onto the back of a Mamiya RB67, so that it can accept Mamiya Press Universal adapter backs, like a Polaroid, a Type "M", etc.</p> <p>Do these rotate between portrait and landscape like the regular Mamiya RB adapters?</p>

<p>I'm curious. Using a Mamiya Press Universal, accessories are available for extending the lens towards the front or extending the back towards the rear. </p> <p>What's the difference? Is there a reason to prefer one or the other?</p>

<p>I'm curious. How do the optics compare between Mamiya Press lenses and RB67 lenses? (e.g. sharpness, flare, distortion, etc.) Are any of the Mamiya Press Optics multi-coated? If so, how can one tell from the lens?</p> <p>I have both camera systems and am wondering about the need to have both.</p>

<p>Hi. <br> Is it possible to use regular Graflex rollfilm backs on a Mamiya Press Super 23? That is, is there an adapter that makes this possible? </p>

<p>I just purchased an Eyepiece Extension for a Mamiya Press camera. It's for using 70mm and Graflex rollfilm backs. To my quesiton, HOW DOES IT CONNECT TO THE CAMERA?</p> <p>Seemingly, it screws onto the standard eyepiece, which has threads to receive whatever. But if there's a threaded portion on the extension, it's only about 3/32nds of an inch long, which isn't very long. And, it won't screw into the eyepiece of two different Mamiya Press cameras. It looks more like a flange than a thread, given its narrow length. </p> <p>It's usable, whether or not one's using the thicker Graflex rollfilm back. (I can tell this by manually holding it up to the eyepiece.) According to the archives, it has a 0.75 negative magnification, which actually makes viewing easier for me in the viewfinder. So, I suppose I could file the flange down enough so that I could glue it onto the current eyepiece. But, this isn't a very satisfying "solution". </p>

<p>I have an earlier prism with CD. It's kind of klunky, etc. What's the difference between this one and the Model II prism for RB67 cameras?</p>
