    This evening I was doing my best imitation of a photojournalist for my uncle's polka band (likely their last concert, family in from out-of-province, full house, etc).

    The basement hall where this was taking place became quite humid over the course of the evening.

    After a while, I started to have 2 unusual equipment problems - one of my Pentax ME Supers started registering all shutter speeds at 1/500 in "Auto" mode no matter what the aperture was set to (which cleared up after I unseated/reseated the lens), and an external flash attached to a recently acquired Mamiya C330 80mm lens started not firing intermittently (it worked perfectly earlier in the evening and with the couple of test rolls I've put through the camera beforehand, and I've used that flash on other cameras without issue for some time). I did have a 2nd ME Super with me, but as I noticed the issue and it reset, I didn't feel the need to switch bodies.

    Now that I'm back home I'm letting the gear air out for a while before I test some more, but I wanted to see if this was a common issue with indoor shoots, and if so, how can I avoid or mitigate this in the future. It sometimes gets humid here, but I'm not often indoors under those conditions :smile:
