Re: Interesting K3III v K1 II

Yes, quite interesting... only complaint is I wish English sub's were available.

The AF on the K1 II did a lot better than I imagined in such a test based on the hype, but gotta hand it to the K3 III , it did appear certainly faster to acquire the moving subject and was more sticky, and stayed locked onto the subject better. My question is this... did they ever do a similar compare to the K1 Mk I ?

The one that kinda was weird for me and seemed counterintuitive was the ISO performance... it wasn't a linear difference at all. I guess it has something to do with the NR engine... because it looked like the K3 III was lagging in keeping the noise down early on, but then surpassed the K1 II once it got up into the ISO stratosphere of where we would probably never use it. It looked to me like the K3 III was retaining enough of the image of those balcony windows to still be recognizable when the K1 II had finally given up and it was just a smear.

Thanks for sharing Dean!.

My immediate question was whether they normalized the shots by using the k-1 in crop mode, or used different focal lengths. The tracking tests looked like different focal lengths. That aside---

I think at low ISO what you're seeing is the full-frame advantage (more, larger pixels, so inherently less noisy), and at higher ISO the advantage of the improved NR engine.

Re: Interesting K3III v K1 II

I suspect they didn't normalize the shots Bob.

AF on the K-3 III is clearly better... no surprise. Overall the K-1 II seems like much better value to me. If the K-3 III included the gps and the very cool flippy screen it would be even better, maybe even worth the price.

I like the extra dof from APSc.
