So, as I reveiw dslr's, I have noticed that most come with rechargeable li ion batts, but the Pentax take 4 AA's.
My questions are:
- what is the thought on using this type of system - is it effective - does it last as long as a rechargeable
- is there a li ion battery you can buy for the Pentax - I am thinking there isn't given the battery cavity, but thought I would ask.
thanks
