I was reading the staff review of the Sigma 30mm 1.4 DC HSM "Art" lens this morning, and it seemed like it would be a really great lens, until the reviewer described its autofocus speed as "sluggish". I believe it was tested with a K-3.
The three most important selling points that interest me are sharpness, autofocus speed, and a broad aperture range.
So I am wondering, instead of reading seven or ten reviews, what lens would you say, zoom or prime, from any maker, covering anywhere between 15mm and 35mm, would focus fastest on the K-3, give impressively sharp results, and provide the creative flexibility of a wide aperture range?
Thanks!
