mode.

There are a few instances of older bodies not operating the cocking lever or the release lever correctly on some lenses.

The 80mm f3.7 has a quirk where the shutter release arm on the lens moves even if the lens is not cocked.

16.2 Film advance problems

The camera advances all the film.

This is usually caused by the shutter release being slightly depressed, often by a long cable release. It is caused by

the multi-exposure interlock being over-ridden. This was a feature to allow film to be wound off quickly if less than

12 frames were used.

Rarely an improperly latched back can also cause this, as the frame counter does not register the film passing

through the camera.

The frame spacing is uneven.

Uneven spacing, but not overlap, between frames is not uncommon on mechanical cameras. Check that the camera

is correctly set to 120 or 220 where applicable, and that the film is tightly wound on the take-up spool when

exposed.

This may also indicate an improperly latched back.

16.3 Focus problems

If you have routine problems focusing the camera, check:

Your eyesight must be matched by the dioptric correction in the finder that you are using. If you cannot see the

boundary of the focus spot sharply, you cannot reliably focus the image. The clear spot/cross hair screen for the

C330 cameras is not intended for general photography.

If it happens with just one lens, it could be that the lens needs adjustment.

If it happens with all lenses, you need to check the finder focus against the body focus.
