I got back a roll of film from the lab and there were some exposed areas around two of the shots. I remember changing lenses mid roll. Can this be done safely on the M6?
 
Also, if you shoot the whole roll with the same lens and without removing the lenscap then it really cuts down on film + development costs . . . . 😉
 
I hope Vincent is being cheeky because as the first reply stated that is the reason to have an interchangeable lens RF. I am just guessing that if the two shots were the ones at which you changed lenses then it may be possible the some internal light sealing is starting to go. I am sure someone that knows will pipe up shortly. It maybe a good practice to change lenses with the camera shielded from direct bright sunlight though.

My guess is you have a bad light shield. I would suggest you send it off to a reputable repairperson (along with some example pics) for a replacement. This is a common issue with all M cameras.

You might also try scanning some examples and posting here for a more definitive opinion. A bad light shield has some unique characteristics.
 
I do not know about light shields in the M6, but the IIIc I had needed to be set right as its lower light shield was letting in light when I changed lenses in the open.
 
Of course there's a safe way to change lens mid-roll: make mental note of how many frames you've shot, rewind film (being careful to leave leader out), take roll out of camera, change lens, put roll back into camera, stop down lens and select faster shutter speed, put lens cap on, click shutter same number of times as you've shot frames plus two. That's it.

I do it all the time.

You can change lenses with no problem. It's logical: You carry your camera without a cap while shooting (at least I do), and light is entering the camera through the lens and the film is not exposed, so it should make no difference if you take the lens and put another.
 
Thanks everyone. Looking at them it looks more like a lens flare coming off of the glass I was shooting at. Or a lab screw up but probabaly mine. Sorry for the dumb question.
 
I've had light leaks on my III that I know are from changing lenses. It might be that having no lens on the body allows light to hit parts that it normally wouldn't (out of the focused light from the lens)
 
Both my M6`s required having the light shields around the shutter replaced. When they were bad, light fogged the film when changing lenses.

Now all I do is turn my back to the sun.

They both were purchased new in 1986 and DAG fixed them in 2001 or so.
Neither camera had more than 25 rolls thru it.

Later M6 cams had a mylar shield that does not go bad.
 
About the pinhole concern, I carry my camera pointing down, or walk with the hand over the lens. I use a 50 cron with the vented hood, and putting the cap on means dettaching the hood, turning it over, putting it back backwards and putting the cap on. A pain.

Any idea what serial numbers would be good?
