K-3 II vs. K-S2

I'm considering K-3 II as upgrade of my K-S2, which would serve as backup body. Having read reviews and numerous threads at PF, I still have one question unanswered - will K-3 II offer significantly better image quality than my currect camera? I don't need dozens of AF points, as I use only central one in 'focus and recompose' mode. Pixel Shift is of limited use outside studio, but improved tonal and dynamic range would be useful. I also wonder whether sensor resolution (20MP) is limiting factor for following Pentax lenses: A 50/1,7 M 50/4 macro, 12-24, 16-85, and 100 macro WR. As I said, image quality is the only criterion. Of course K-1 offers top image quality, but I do not consider such purchase.

In a word "no" I doubt it.

The image quality is certainly a step up. You get 14 bit color depth instead of 12, a bit more resolution, and most importantly, an improved metering system that will get you better colors in low light.

That said, of you want a significant improvement, the K-1 is the way to go. Time to start saving, perhaps?

No. In a double blind test you likely would not be able to tell the difference.

I can't say as I don't have a KS-2 to compare with - I have seen people who have done the comparison and came away saying the KS-2 was the better sensor. The likely situation is that you would be hard pressed to see differences.

I've compared the k-3 and the k-s1 directly. The white balance and colour accuracy of the k-3 makes editing the RAW files a little easier (also helpful in tricky lighting conditions). The high ISO noise of the k-s1 is better though (not massively, but it is noticeably better at 3200/6400). Really though, aside from pixel shift, there isn't a huge difference in image quality. The k-1 on the other hand - that is a big step up in image quality! I'd probably recommend saving up for a while longer and getting one of those...

Thank you for these insights - looks like I have no other choice, but to spend money on better lenses, or even buy K-1 Anyway, K-S2 won't be replaced by K-3 II. Thanks again!

I really like the K3 usability features like the 100% crop on review. I'm constantly zooming in with my KS2 to ensure sharpness and it kills me that I have to buy K3 to get this feature. The K3 has other features that I would love to have on my KS2. The K3 lacks the swivel screen and being from the new age of photographers, I love this feature as I use that rear screen quite a bit. Just wish it were a touch screen. Most of my mature photo experience has been with touch screens as they are easier to work with.

Re: touchscreen
I'm from the not touchscreen world and having difficulty getting used to touch screens. It should be easy but I'm so used to how I operate a camera. Lol
