I take that back, I read the manual and it seems it has an electronically-timed shutter. Now that I think about it I used to have two replacement batteries in the bag, but In the years I owned mine I never had to replace the battery so I guess that's why I never thought about it. The manual stated the battery will last about 8000-10000 exposures. Honestly, you can't go wrong with a Pentax 67, they are total classics and I know fellow professionals that are still using them for documentary and street work.
