Ok, so I picked up a Mimiya 1000 DTL the other day, thoroughly examined it and it looked like it was fine. Ran an older roll of kodak B&W through it, and most of the roll seemed fine, but there's a few problems. 1. The shutter stuck once 2. The meter seems off. I went and had the battery replaced, and it still seems off - off as in, if I set exposure to 1/8, then everything is correctly exposed according to the meter - there's no variance with aperature. 1.4, exposure fine. f/22, exposure also fine. 3. The self-timer seems odd, it worked fine a few times, then seemed reversed for a bit, and wont work right. A few more advances, it was fine once more. So, I'm thinking it might just need a general cleaning? The seals and such seem fine though I couldn't really examine the mirror damper. Im getting ready to send it to camera repair.com, but was wondering if there was anything I could do before that. Thanks!
