Hi all, long time no post!
I was given a K100D, body only, but it has a real battery use issue. I'll give you all a step-by-step on what I've done.
I was given the body in January, I put some AA rechargables in it and it wouldn't turn on. I didn't know if the body was dead (I had no history of it) or the batteries didn't have enough juice to fire it up. I put some brand new Energiser Alkalines in it and it fired up no problems, but i couldn't test it because it had no card or lens.
I got the camera home and put my M-50 f/2 on it and put some 2600mAh Ni-Mh rechargables in it. These were straight off the charger and last for AGES in my K10D. I got the settings adjusted how I wanted, took 6 photos and the camera told me the batteries were depleted. Before the batteries went flat I did find out that it only had V.1.00 of the firmware.
Tonight I thought I would do a firmware update on it and see if that fixed the problem. I charged my near-brand-new Sony 2700mAh Ni-Mh rechargables, formatted a card and updated the firmware. The batteries lasted long enough to do the update (latest download off Pentax, v.1.02). I set the camera up again and took 1 photo and the camera said Batteries Depleted!
Does anyone have some suggestions on what I can try to gains some better battery life out of it? The camera functions fine...it has me beat.
EDIT:
Interestingly I turned SR off and I've been able to rattle off quite a few shots and it is still holding full charge. Anyone got any ideas?
Images seem pretty good, a fair few hot pixels at ISO 3200 (all of these), here are some I just took from my lounge chair. That camera hasn't even done 2500 shots either.
