I found the performance of the lens (focus, noise, sharpness) to be reasonable, particularly given the price point, which was just under $200 CDN new.

I actually returned the lens, so I had to look through the test shots I took to discern corner sharpness. Based on the shots I have on file, I don't see much in discernible sharpness loss on the corners in FF, particularly at the lower apertures.

Hi everyone,
I am a long time Pentax user, and a great fan (and long time lurker) of this forum... This is my first post, so apologies if I am not following site posting etiquette:
I have recently acquired my Pentax K1 and I have been trying out my various DA lenses.
Tonight I tested my DA 35mm f2.4 AL, and I am certainly finding some vignetting between 2.4 and 4.5. Vignette at 2.8 is very pronounced, and quickly recedes after 4.5.
After 4.5, the vignetting was more or less automatically dealt with by Lightroom lens profile correction.
Attached (I hope) are 4 photos I took tonight. RAW from camera and spit out via lightroom.
F2.8, F4.5, F9, F11 respectively.
Cheers
