Originally posted by Vallista Ok after long some research, I found out the K-1 can do about 750 shots on one battery. I don't know if that includes raw shots or not. my current nikon D750 does about 1000. So this might work for me.
I was looking into the sony alpha 7 mark ii but battery life sucks. My only other concern has to do with HDR and if K-1 has it or not.
The battery-life isn't much affected by writing raw, jpg, or raw+ . But your HDR-Option may use some power, the same way as all the correcting math for jpg's.
Most of the energy is used by the usage of the Back-display. On my K-3 I hve typically up to 1300-1400 pictures (not using the internal flash) and not viewing the pictures intensive after each shot.
On the K-1 I'll hope, there is no need for a BG anymore - I use one one the K3 (with the spare accu), because of my big hands. And the accus are so small that it is easy to have one additional in your jacket, this will be enough for more than one day with heavy shooting.
The BG6 of the K1 isn't kompatibel to the BG-5 of K3, different mechanical layout of electrical connector.
