Originally posted by panonski So, the bootom line, is I'm very well awared of limitations in AF , that can be tricky in shooting.
My K3 behaviour in AF-S is very incosistent... from 10 shoots, spotted on the same AF target place - several of them would consider well focused, after that, several would be slightly out of focus - and maybe one or two in best way would have maximum sharpness...
Of course I'm talking about shooting and focusing throught the mirror - or shooting with OVF ...
Results in AF vary to much for my personal taste, and that's not a so good thing, when you have exscesive shooting of model, or more of them, and later in desktop you find out - that most of the pics, are - well - slightly out of maximum sharpness, while some of them reach that level.

I read in Kp official Ricoh page, that KP has a new SAFOX 11 AF module, with lower apperture pass at 2.8, vs older version which is only 5.6....
Pentax statements here are :
" SAFOX 11 New-generation AF sensor module with a high-speed algorithm The PENTAX KP incorporates the high-performance SAFOX 11 AF sensor module in its autofocus system. This dependable module features a diffraction lens to effectively compensate for chromatic aberration and assure pinpoint focus on the subject, even under adverse conditions such as when shooting against backlight or photographing high-contrast subjects. High-speed AF algorithm This latest autofocus algorithm assures a faster autofocusing speed than the one used in the conventional SAFOX 11 module. It lets you react more swiftly and effortlessly to unexpected shutter chances." Features4 | PENTAX KP | RICOH IMAGING

i WOULD LOVE TO SEE SOME REVIEWS FROM KP USERS HERE..., specially from ones who are still engage with older K 3 or different bodies

Thank yOU ALL
I share your experience with the K3 auto focus behavior. I no longer have the K3, but used it for four years with the DA560, and worst was initial focus acquisition. When there was little time for a single shot, I would aim, focus and shoot, and often the focus would be just off, or sometimes even far off. When abundant time to pamper the shutter button, I could also get a reasonable amount in focus, but many shots would often still have an amount of blur. I am not alltogether sure though, if it was only the AF inaccuracy leading to slightly blurred shots. It may also be sometimes due to SR or shutter shock, even if that should not be the case with shutter times like 1/500s.
Now with the KP, everything feels much more secure, less buggy, more confident. That also goes for AF. Without doubt, focus is more responsive and faster with the DA560, but also hunts less around the subject, something which my K3 did a lot, many small corrections, and although too early to give any solid opinion, I already trust my KP much more than I ever did the K3.
Energy supply seems much more stable: even on a nearly depleted battery, the KP still performs exactly as with a full battery. My K3 would start acting up on a battery less than half charged: fits of unresponsiveness out of the blue, irratic misfocussing. Not all the time, but it does indicate, that stability was not my K3's forte. The KP feels much more "high end" to me than my K3 ever did.
So to me, Ricoh/Pentax is on the right path with the KP. I hope they advance further.
Also, experimenting with the electronic shutter, that automatically disables SR, I find that many shots have less blurring. I hope Pentax will also get access for the next APS-C body to a sensor with faster readout time to make the electronic shutter more practical.
