<p>I recently purchased a used Yashica FR I with a ML 1.7/50 attached from a local fleamarket, mostly intending to run a couple of rolls through it and then sell it, as I have decided to stick with mechanical cameras in the long run (Yashica Electros excluded).<br>
Using the camera has been fun, as it really feels like a well-made precision tool, very solid with good ergonomics and very smooth feeling overall. So the notion of maybe keeping it for a while started forming in my mind, until I received the results from the three rolls I shot during my holidays, most of the pictures having been ruined by severe light leaks. Before starting using the camera I went through my usual routine of replacing the light seals and mirror bumper which has proven very effective for all my used cameras so far with no problem whatsoever. I normally use black cotton string on the body to seal the film door, so I added a second layer of string and shot a fourth roll, but the problem remained:<br>

Checking the negatives, the leak extends over the lower sprocket holes (which corresponds to the upper part of the door as the image is reversed, right?) but not over the upper sprockets. However, the constant location and vertical edge of the leaks on the negative plus the fact that some of the pictures turned out OK, made me think that there could be some problem with the shutter curtains at certain speeds. If this is the case, why do the leaks extend over the lower sprocket holes? Doesn't that point to a door leak, or not necessarily? I reinforced the light seals by adding foamy material along the door edges (where the original seals were) and reloaded the camera, but I would like some advice regarding the source of the problem before ruining one more film roll and what could be done to determine the source of the leaks without specialist equipment (if possible). </p>
