Hi Folks,
I recently purchased a Toyo 45A with a rotating back and am still learning how to use it. I am new to LF so I am still trying to learn the terminology and what is compatible with what camera. It appears that the Toyo rotating back is a "spring back" not a "graflok/international back". Is this correct?
I ask this question as I am unable to figure out how to use a Graflex Graphic 23 roll film back with it.
The mechanism that holds the rotating back on works very similar to a lens board retention mechanism on the front of the camera. The height of the rotating back, unsurprisingly, is much larger than that of the roll fill back so it is obvious I cannot just take one off and put the other on.
Is the Toyo 45A incompatible with Roll Film adapters for Graflok backs or am I missing something? Does anyone know if the Toyo 6x7 Roll Film Adapter will work with this camera or am I stuck with ones that are the approximate size of a cut film holder (i.e. Calumet C2)?
Also, everything I read about the 45AII (I just have the 45A) talks about a frensel lens on the rotating back, but I don't have one. Is this normal for the 45A or am I missing one and perhaps going to have a problem focusing?
