See my Pentax K1 wish list at B&H Photo.
But the Pentax lens line is at best mediocre, the biggest thing holding the K1 back from high performance, something I observed firsthand in the field using the Zeiss ZK 28mm f/2 Distagon, whose performance I found quite satisfying.
Now, Leitax is shipping Nikon and Zeiss ZF to Pentax K conversion kits. Nikon F-mount lenses with an aperture ring can be converted to Pentax K mount and this conversion is reversible. In particular, my favored Zeiss ZF.2 lenses (Nikon F mount) can be converted to Pentax K mount. Leitax will also convert your lens for you for 75 Euro (plus the cost of the kit and shipping).

Writing to warn you that the Leitax mount cannot be installed on all the Nikkor lenses with aperture ring. Only on those without CPU and that allow to remove the original mount clean, without any attached mechanism. I will show it in the instructions for Nikkor lenses soon.
The Zeiss ZF.2 lenses have CPU, but have the chip attached to the mount, and it goes off together with the mount, so no problem with ZF.2 lenses. But the CPU Nikkor lenses have a flat cable going inside the lens that connects the contact strip at the mount with the chip, autofocus motors and data sensors inside the lens.
DIGLLOYD: all Zeiss ZF.2 lenses contain a CPU chip. The original ZF lenses do not.
