Just developed my first roll of 120 from my Yashica LM in a Rondinax 60 that I recently won on an auction site. The auction included a Rondinax 35U as well. I used the 35 first time yesterday. It (the 35u) worked like a charm. I did have some trouble with the 60 at the point where you pull the paper which in turn loads the film into the film chamber inside. It started an accordion roll instead of loading the last three frames, which would be the first three frames on the roll. I lost those three frames.........but the others seem to be perfectly fine. Those negatives are huge compared to 35mm. It's on now. I'm gonna start looking for a 6X7 of some sort. Maybe an old folder from Certo6. I just needed to know that I could develop my own. Has anyone else used the Rondinax 60 and had this same problem with the film not loading properly?
