Does anyone elses rangefinder window look like this? Not sure if it's supposed to be this way, with that little L shaped part sticking up slightly...?

this is on an MP, btw.

Hi Daniel,

Can't see it at mine M6TTL (with MP finder), yellow part is not visible.

But I do have a Minox with a Larval form of Anthrenus verbasci

(Varied carpet beetle) inside

Hope this is some help

Kind regards

Ruben

I don't have that apparent sloping gap with the yellow. Could be worth following up..

...just checked both my MPs and neither has the L-shape feature nor the yellow/orange bit that is visible in yours, Daniel. Have you determined if your focusing is out?

[danielericweiss]

My focusing is actually fine, but I have been having intermittent light leaks. maybe every 6 rolls or so, here's a couple examples.

 

 

have deduced (with some help) that light could be leaking through here.

Possible, it looks like your rangefinder unit isn't sitting flush internally against the 'windows' and light leaks can occur from the rangefinder/viewfinder area.

 

However, the leak looks like it could also be a shutter problem to me, due to the bands which would correspond to the shutter aperture/travel.

 

Either way you need to send it off to the repair man for attention.

If it were a shutter problem could it really produce 3 bands as shown in one of the frames with the rest of the photo properly exposed in between the bands?

1. It does look as though something is out of position in that window.

 

2. Light leaks from that area are quite possible. I had an M4-2 in which the rewind clutch lever "R" had too long a shaft, and thus stood out away from the body. And it leaked light like a cathedral window right onto whatever frame I had last exposed as it sat in the gap between shutter and take-up spool between shoots.

 

(A machinist where I worked ground about .5mm off the back for the "R" lever shaft to seat it tightly, and the leak went away).

 

The removal of the self-timer mechanism post-M4 leaves a hollow area that light can transit from the front top right of the cameras if there are gaps in the assembly.
