Originally posted by Rondec I guess so, but it already takes a long time to transfer 20 or 25 images from my memory cards to my computer for editing. I can't imagine if I had 60 or 70 45 megapixel images to transfer and then edit/delete. Half the time I have my K-1 in single shot mode.
I'm not sure folks who have teased the 8 fps out of a K-3 think that 10 FPS should be a thing. I have sat in post and gone through 15 identical images, tossing only based on random choice, because there was no discernible difference. 8 FPS is one frame every .125s. 10 FPS is .1. Some people think that .025s makes a huge difference. Myself, I've been surprised how many times going back to the 4 FPS of the K-1 doesn't bother me. Most of the time my decisions now are based on whether I need the extra reach of the K-3.
Honestly, process a few 23 shot bursts with a K-3. See what you're getting. Much of the time the difference in what you get isn't worth the extra files you have to process. A lot of the time you get nothing special anyway. Nothing special is definitely better at 4 FPS.
I'd probably go for 9 FPS as part of an upgrade, but 7 FPS with focus confirmation turned on would be better.
