when i did the test roll, i listened for the shutter to work each time, and for the mirror .

I made it somewhat easy because i was running the shutter at ALL speeds. started at 1/1000, worked my way down to 1 second and worked my way back.

Yeah, like the other said, check the counter and write it on the cassette when changing out a partially shot roil.

I don't really like to do it if I can at all help it. Buying another camera body and having a few with different kinds of film in each is pretty affordable these days.

Well the issue is that i had a new lens to test, and i swapped it twice with the one on the camera.

i did NOT fire the shutter with the lens off. I did that when i first got the camera by mistake, and lifting the mirror and firing the shutter on a canon ftb when the lens is off WILL kill any film outside of the canister, its not fun.

I also got on this roll, and randomly over the rolls i have shot, frames that are really really out in exposure. Almost a +8 but the meter was always balancing out on the needles.

Possibly an issue with the full advance mechanism.

advance on teh canon was perfect, its a perfectly clear frame, looking under magnifying glass in better light i can see SOME dark spots appeared in these frames. so im rather confused as to whats causing it.

Its NOT like the sun flare i had on another frame in the roll so its just pissing me off.

Of course! That is why the camera has a focal plane shutter!

Truly? I knew several owners of breach-lock Canons back in the day and don't remember any restrictions on lens changing. The only thing I might imagine is if the shutter is armed and fires with the lens off. (Note: I just consulted the user manual for the FTb from the Butkus site. The instructions for lens usage (pages 35 and following) are complete and should be uncomplicated with lens in hand. If there is a way to bung things up as described, it is not obvious, nor is it called out in the guide.).

FWIW, Tuco is probably one of the better resource people on this site in regards to film cameras, all makes. Trolling is not his thing, though he did miss the reference to FTb camera in your post.

Might have been a little mean, but if you wish we can discuss my charming love for "photography forums" in general.

And NO, i dont consider PentaxForums a "photography forum" as i dont see any one being banned for disagreeing with a moderator about the proper method to remove film from a canister for processing.

when you read the FTb manual at that link, on page 18, 21, you see a diagram showing how the needles need to be balanced..

ie with the needles completely on top of each other.. Funny note, ONLY the 50 mm lens can do that.

The quirk is that you need to get the shutter needle to cross on the circle itself or to hit the spot the circle joins the needle on the aperture needle.

the photrio kids say the circle represents an entire +1/-1 of EV in the meter..

I had a Canon FTbn QL and I never experienced anything like OP describes. It's a mechanical shutter with speeds from 1 to 1000, breach mount takes FL (stopped down) or FD lenses. There is a mirror lockup switch off the self timer. When it properly working, locking up the mirror and releasing the shutter with or without a lens exposes the current frame only. Removing the lens doesn't fire the shutter or advance the film in a properly working body.

never said the camera fired nor mirror move, have actually said those things never happened.

Sorry, I misunderstood how mirror up was contributing to this...

"and lifting the mirror and firing the shutter on a canon ftb when the lens is off WILL kill any film outside of the canister"

I assumed this meant all the film outside the canister...not just the current frame.

Never experience that in almost 50 years of shooting Pentax film cameras. Spotmatics, SF1 MX, MZ series or Auto 110.
