Pentax FA 31mm f/1.8 AL Ltd vs Voigtlander ULTRON 40mm f/2 SL II

The Pentax 31 cost 55% more than the Voigt 40. Does the Pentax lens justify the extra $$.

Either focal length is fine for me. Am looking for sharpness, contrast and best IQ in the field from a fine compact prime lens. (Any other 30 - 40mm lens I have overlooked?)

Thanks

the FA 43 ltd would be more comparable to the ultron 40mm. plus the 43 is cheaper than the 31.

You probably overlooked whole bunch of 35mm lenes. DA, DAL, FA and the f1,4 samyang.

Indeed, the FA 43 Limited is the Ultron's true competition in Pentax K-mount. PhotoZone has tests of both lenses on comparable sensors and both did very well. The Ultron is sharper wide open with less vignette and CA overall. The FA 43 is sharper from f/2.8. Both have excellent build and are very compact. If I were trying to make a decision between the two, it would be a hard one to make

(BTW...Where would one purchase the Ultron in K-mount. I thought they were sold out used?)

I post a thread asking for FA43 vs VL40/2
no conclusion was drawn but I got a FA43 just because a deal came up for it.
Now LBA kicks in and I am looking for VL 40/2. lol
