I think it costs a lot of money and very dreamy at 1.2

MF with 1.2 will be difficult (A nightmare!)

I think that even with AF focussing will be a nightmare!

That's not a problem. The 50 f/1.2 is only available as a K and A lens. No autofocus version exists.

The AF System of the actual Pentax cameras (do not know AF of K3) works at the 5.6 Level accuraltelly.

The K5ii and iis both have an f/2.8 sensor in the center. The K3 has three of them I believe.

Maybe the lens will be an Advantage to give a lot of light on the sensor and so the AF System gets enought light to wark at low light - but I would not use this lens at Maximum aperture opening.

If I had known how much ISO performance was going to improve I might have just gone with the 50 f/2.8 macro instead of the FA 50 f/1.4 I have.
