I just bought an Onito on the 'bay, primarily for the Rollex film back that came with it. It's a sweet-looking little 9x12: decent bellows with a Nettar 135 that is clean and clear in an Ibsor shutter that seems to be quite good. I want to try it out. Only problem: The front standard will not move out along the track, but stops with a bang just about 1 cm into it's travel. I found that the brass slides on the standard were a bit bent and straightened them out but no go. There appears to be a small post under the standard that may be catching on something -- don't know, but I can't reach it. The solidity of the catch when it stops seems to indicate that it is either entirely broken or I'm missing something... Any experience out there with this thing?
