I purchased this for my Leaf Aptus 22 and it worked great.
Moving back to analog for my MF and LF, so this is redundant.
Comes with:
The sliding adapter. This fits on all Toyo and Omega 4x5 158mm cameras. Will allow a film back to be attached (although I don't know how you would control it - it does fit)
Mamiya RZ67 WLF
Mamiya RZ type A screen (the sliding adapter has a focusing screen in it, this is an additional one, this one is brand new and unopened)
Connection cable for the back.
Original box
$400
(Toyo 45A in images is not included)
