I am thinking of get a 5X8 camera, it can also use 5X7 and 4X5 back. I searched the forum and didn't find too much info about it. I don't think there are a lot of people shooting at this format, am I right? I guess this kind of camera would be a little bit bigger than 5X7 camera, but can anybody who used this kind of camera tell me exactly how big is it? Is it just a little bigger than 5X7 or it's close to the size of 8X10 camera? Another question would be the lens. I assume the lens used on 5X7 can be used on 5X8 but with more limit movement. Thanks in advance for comment and suggestions. PS. I only plan to do contact print with this format. Alex W.
