Pick up this little gem for $5 at a garage sale, along with a Minolta MC-ROKKOR-PF 58mm f/1.4 for $10.
Vimeo: Kiron 24mm f/2 by Kino Precision Japan lens review.
Now here are lens chart and landscape stills of this lens vs. the Canon EF 17-40mm f/4L USM lens at 24mm (just for comparison). My initial thoughts were that the Canon will win even thought it's a f/4 zoom...but I was pleasantly surprised.
Still landscape tests:
ISO 100, f/11, 1/60th sec. 21MP RAW with all in camera settings at neutral. Processed with LR2 with zero NR and Sharpening, 10% contrast, and slight EV adjustments, exported to 100% jpeg
Kiron 24mm f/2 at f/11
Canon EF 17-40mm f/4L USM at 24mm and f/11
Lens Chart test, ISO 160, 1/30th to 1/5th sec. Same processing as the above landscapes.
