Reviving this old thread - but relevant as it is about battery life and I'm bringing new info.
Originally posted by Eulogy Pentax F works with practically ever Pentax camera with an IR reciever.
I confirm that it works with the K-1
Originally posted by mtansley The K-5 manual says that it should last about 30,000 times. (I wonder who was selected to push that button 30,000 times to find out that information!!)
I wonder who needs 30,000 selfies? A mega-narcissist who needs help!
Originally posted by Ubuntu_user Does anybody know how long the battery is suppose to last, with light/moderate use?
I got one 12 years ago with my K10D and it still works on the original battery. I expect the battery will last its shelf life unless you are that mega-narcissist.
