^x7 underexposure

Has anyone identified "Curtain hang-up"? -or ?? I have several

frames on several rolls, intermittant of course, that appear to be

underexposed and unevenly so. That is, one side of the frame worse

than the other, and some apparent banding in the murk. I first passed

it off to my own ineptness, trying to shoot action with two bodies and

not checking settings etc, but closer examination shows possible

banding. Thanks

Hi Ed

I've not had problems with a banded exposure but my 67ii has just been returned to Pentax UK with an exposure problem. On the same roll some frames are spot on and others up to 2/3 stops underexposed - same subject, same lighting & doesn't matter whether taken in Aperture Priority (using the AE II prism) or in manual. An intermittent problem like yours.

This is the second problem I've had to return it for (its only 15 months old) - was (and still is) prone to giving me completely blank frames mid roll for no apparent reason.

Think I'll trade it in!!

Sorry this doesn't help you but I wondered if we had company in having a bum Pentax 67 camera?

All the best

Steve
