I'm glad someone brought this up. It seems that any
camera on the site in question is a direct rip-off of
others ideas and concepts. I am all for free-trade
and commerce, however, I would have a greater respect
for an original product line - not just
reverse-engineered copies.

If the camera has a curved film plane, there will be no fall off.

First they copied Zernike Au designs and now they are making this camera. I
wont be buying it. It must be hard to get 120 film to span across the 22cm
back. I will wait and see if Zernike Au makes a new camera. Much better to
buy an original than a copy.

The camera is said to have a 60mm focal length. Does anyone have
experience with images made that wide, nearly 8.5 inches, from such a
focal lenth (at f/360) on 120 film? Are the edges even useful at that
extreme?
I guess what I'm getting at is this camera a gimmick? Will the user
