Hi all!
Just picked up a used Mamiya 6 with the 75mm. This is my second Mamiya 6 - sold my first one a couple years back, regretted it immediately, finally snagged another.
First couple rolls have been sharp as a tack, very pleased. HOWEVER...
...most of the shots have been focused within 5 or 6 feet. If I'm focusing on anything after 7 feet (2 meters), the horizontal image starts to reverse and go back the way it came (to the right) rather than bring the images into focus together. I haven't noticed anything out of focus on film, but it's obviously making it hard to focus on anything that isn't seven feet or closer.
This doesn't seem like the typical Mamiya 6/7 "rangefinder images don't line up at infinity" complaint, as we're talking about fully half of the focus range of the lens being off with the rangefinder.
The little black knob that hides the rangefinder screws was haphazardly glued in, which gives me the impression that a non-technician was in there tinkering around. I lost the knob itself, so all that's separating me from those adjustment screws right now is a little piece of black electrical tape... and it's VERY tempting.
Should I pump the breaks? I'm assuming I'd be adjusting the right side screw that controls the horizontal image, but I'm not sure what I should be adjusting it for or in what direction.
Any thoughts or ideas I would love some insight!
