If it really is a register problem, the mirror should bang into the rear group if the lens is at or near infinity - there should be no issues close-up. It might be worth while to see whether it isn't really a mount or adapter issue with the aperture coupling! _________________ Sevo |

you are correct, sevo, on when the rear of lens protrudes most into the body. if so, then i have no clue as to why. i was shooting wide open, as i have done before with helios with no issue. there are no issues with a 55/2 super takumar, or spiratone 28, or vivitar 35 or ivitar 135. hmmm ... _________________ Paul

You sure it's hanging on the lens itself? If so, then just remove the lens, no? I guess I don't understand why you would lose 9 frames because of this...
The helios 44-2's elements only protrude about 4mm past the mount, which is relatively nothing. My older biotar comes out around 11mm!

I fixed this on a spotty by removing the bottom cover. There's a pin that needs `adjusting' and maybe lubricating. It's fairly simple. _________________ Casual attendance these days |

This can't be anything to do with the lens. The 44-2 doesn't protrude as far as the Super Takumar 1.4/50, which originally partnered the Spottie. In fact the camera works OK with the Mir-1B, which protrudes even further. I don't know of any M42 lenses that can't be used on it.
Need a bit more info on the problem please.. _________________ Peter - Moderator |

i pulled the lens and gently poked at the edge of the mirror. it swung down. then i foolishly wound the camera and fired a shot with no lens to see what would happen. the shutter stopped part way open. (it is difficult to remember the details because of frustration.) i knew that fogged a frame or two or three. so i wound off all the film and processed it today. seven shots developed. one of those had a flare. the other six look fine. so i lost more than nine. anyhow, everything seems to be working just fine now. the foam actually is not brittle nor sticky, by the way. aieeeeee! _________________ Paul

Sounds to me like a CLA may be needed for the camera. I have a few Spotmatics and pre Spotmatic Pentaxes and on a couple of the oldest least cared for ones the mirror hangs. Its probably a lube issue or some such problem and easily fixed but I never have bothered - these two older cameras of mine are beaters and I have others so it would not be worth my while paying to have them fixed. Yours may be a different story. _________________ PeterM |

You can always wind back to the leader after making a note of frames exposed, then put the film in your other camera, put the lens cover on and hold it say against your chest (or hand) and also cover the viewfinder (this is to prevent stray light from getting in) whilst winding and firing the shutter till you get to the fresh frame, with one blank added on in case of error. _________________ Canon A1, AV1, T70 & T90, EOS 300 and EOS300v, Chinon CE and CP-7M.
