Light leaks at the begining of the rolls

Neofito · Oct 30, 2023

What do these light leaks look that are coming from? are rolls that I bulk loaded with an AP loader, so should be reliable. And are new plastic AP rolls. Is just the first 4 o 5 pictures from various rolls, so, near the lead. The camera was an OM1N that I changed myself all the light sealing when I bought it earlier this year. But maybe by the angle and so you can deduce better where is coming from.

Light leaking at the beginning of film rolls implies the cassettes are to blame. They may be new but that doesn't mean they're not faulty. Examine the felt.

I agree. That is what I have experienced with some cassettes. Five frames in points to cassette problems.

Given the position of the light leaks, I'd wager that the end cap doesn't fit securely and leaks light.

A customer of mine always had light leak issues at the start of his rolls ( Leica M4 ), but the problem mysteriously disappeared after he put the camera in it's ever ready case !

Except for Leitz and Zeiss cassettes, faulty cassettes are the reason I gave up bulk loading decades ago. I also load Minox and Minolta 16 because there is really no other choice.
Generally, I find bulk loading to be false economy.

Agreed about the Leitz cassettes. I've had good luck with Nikon cassettes in my Nikon F's too. I bulk load mostly because I prefer to shoot 12-exposure rolls.

That makes sense.
I have a Nikon rf camera, but never encountered any Nikon cassettes that were affordable. Lucky you!

I get minor leaks on like the first frame and some rebate exposure with both metal and plastic cassettes but never anything like that unless the end cap falls off because I dropped it on the sidewalk...happens.

I'm not 100% sure it's the cassettes...there are other issues as well, check out those scratches.

I didnt expect it to be so problematic. Maybe reused ilford or kodak works better? I dont understand why they make a faulty 2€ magazine to handle exxpensive film. I will look closer next time and start to discard the faulty ones or try to fix them.

The scratchs well, I had some problems while loading to the reel but since it was a test roll I just loaded fast without much care, but I am not worried about that, I know why it happend.

As people have suspected here, I am sure the AP cassettes are at fault. Check the area below the felt, you'll most likely find a manufacturing error - the plastic there is scorched because the felt is not being glued but "fused" with the plastic of the cassette.
I've bought 5 pcs and all had the same defect but it is easily repaired with a tiny piece of black electrical tape.
