My mother-in-law had a Pentax SF7 (SF10, I believe, in the US) stuck in a box in the back of her dining room cabinet. It has a Pentax Zoom 28-80 lense attached. Everything seems to be in absolutely perfect condition..if a little bit dusty.  

From what I can tell from the internet, this camera  (and lense) seems to be about 16 years old. Does anyone know anything about it?  It has a very strange nonrechargable lithium battery that I don't know if I can find these days. There is also lots of visible dust on the little mirror thing inside.  It feels nice in hand.  Is it worth trying to bring this camera back to life again?

I'm hesitant, anyway..digital photography is so much more affordable for the kind of work I  like to do. I couldn't really make a dark room anywhere, and I'm not about to shell out heaps of money to get film developed.

Anyway, I shall stop rambling. Any insight would be appreciated. :)
