Which Sigma 12-24 lens mount is compatable with K1

sybil8 · 12-23-2018, 10:54 AM

Hello,
I am looking for a full frame UWA lens for interior painting studio shots (tight space 20 x 15ft, large works) ,I have 50mm and 35mm primes for individual paintings.
I currently have a Fuji-X 10-24 APSC which is ideal for this but want a Pentax K1 FFcompatible lens, Sigma 12-24 seems ideal but I'm not sure which lens mount model works with K1, also I have a FAJ 18-35 but its not quite wide enough,would the image quality of the Sigma 12-24 significantly better?
Any thoughts would be greatly appreciated.

This version is full-frame compatible:
Sigma 12-24mm F4.5-5.6 EX DG Aspherical Lens Reviews - Sigma Lenses - Pentax Lens Review Database

If you're looking for the best ultra-wide image quality in a zoom, there's really nothing that can compete with the Pentax 15-30mm, however. The latter is also available new.

Not sure about your mount question? The K mount is what Pentax uses so any K mount lens would be compatible with the K-1. Perhaps a wide fixed focal length lens would serve you better if image quality is most important? Auto focus wouldn't be required either with a static subject along with such a wide angle. There are some moderately priced prime manual focus lenses that might fit your needs, depends on whether you think you need auto focus and what you want to spend.

Ok thanks all,
I'm clear about the mount question now, thanks. Auto focus is not critical and budget I am quite flexible on.
Would IQ be significantly compromised between zoom (15-30) vs a good prime/legacy adapted prime? I suppose a wide prime Pixel Shifted would have latitude for cropping.
