So I have a Jobo 3006 and a couple of 3010 drums. The 3006 is specifically for 5x7 and the 3010 is 4x5, but I can't understand why Jobo doesn't mention 5x7 for the 3010. I just put a sheet in and it fits fine (since depth is 5"). Is there any reason why one *wouldn't/couldn't* process 5x7 film in the 3010 ? Has anyone used their 3010 for 5x7 as well ?
