Mamiya 6 MF
The Modern Mamiya 6, as opposed to the older Mamiya 6 folding cameras, is one of the finest medium format cameras ever made. I don't feel like I need to go into a lot of the basic functional details of this camera as information about is commonplace on the internet. What I will do is discuss a few scenarios related to this camera that I've had to deal with.
Bellows Light Leaks
One of the neat features of the Mamiya 6 is that like the older folding medium cameras that came before it; the lens can collapse into the body to make it more compact for storage. While on the outside the camera looks modern with the plastic shell between the lens and body, on the inside is a set of bellows like the cameras of old.
This shell is a neat little feature that not only gives the camera a modern appearance but also provides some protection against damaging the bellows.
But don't be fooled, the shell over the bellows does not make the camera light tight.
When I got my Mamiya 6, I was seeing odd flaring on many of the negatives. A little inspection of the inner cloth bellows revealed a small tear along one of the folds.
This leak was an easy fix though. A little piece of black crepe tape over the ridge that was tearing has put an end to the light leak.
Sudden Unexpected Film Advance Freezing
Another little quirk I've experienced with this camera is occasionally after taking a photograph is that the film advance won't unlock. This issue ends up making it impossible to use the film advance lever to move to the next frame.
If this happens, there is a small manual release button just below the lever on the right side of the body. Pushing it with a paperclip, or other little tool frees the advance mechanism back up and allows me to keep photographing. I now keep a paperclip in my wallet just in case this happens while I am out and about.
