Hey folks, I have a nice old Asahi Pentax K (no meter) which came out of my aunt's attic a while ago. (I am not, I guess, a "serious Pentax photographer.") It handles great and has wonderful lenses, but when I developed my test roll I found a few pictures where part of the frame is dark. It looks just like a flash shot with the shutter set faster than the sync speed. In my case, these were all existing-light shots. I didn't keep a log, but I have a feeling these may have been shots where I set the shutter to 1/500 or 1/1000. I can't be sure about this though. Anyone know what might be happening? I tried to upload some examples to my user gallery, but they haven't appeared. I'm fairly new to this forum, so maybe I'm doing it wrong or it needs to pass through a moderator--anyone want to offer website help too? Thanks!
