Ok, I bought this M3 recently. When I purchased it I did the light through the curtains trick in my dark bathroom several times with no signs of pin holes of light coming through.
The area surrounding the backdoor had been resealed fairly recently as that was the source of the light leak.
Previous owner assured me that it was light tight.
I sent the body off to Youxin for a CLA as the shutter timing was off compared to myMP. I finally got around to developing my one roll of b/w I shot through the cam and low and behold thereís a light leak.
Iím so frustrated. I can see it being the strap lug but also I know curtains tend to go. What kind of leak does this look like to you?
