My 18-55 kit lens isn't wide enough for me but I went to the store and looked at the Pentax 14mm prime and the fisheye distortion was too much for me.
Cant you tell me what you think is the widest lens available for Pentax with the least or no distortion?
thanks.
Are you sure, when you say "fish eye" distortion i.e. curvature of lines, you are not confusing this with perspective and converging lines?
I can't speak specifically about the 14mm, but I would be shocked if there is major barrel or fisheye distortion.
I have a sigma APO 10-20mm F4-5.6 EX DC, and while some here seem to dispise sigma, I have found the lens to be excellent quality for the price. I believe the pentax 12-24 may be better, but I can't really comment, the only comparison I can make is with the Tokina 12-24 that my brother in law has for his nikon. From seeing his shots, I would say they compare equally with my sigma.
I have looked at my photo's from the sigma, where I take about 12% of all my shots at 10mm, and have been very hard pressed to find significant distortion.
If you are looking for a good wide lens, with some flexability, I would say any of the current available offerings are excellent, i.e. pentax 12-24, sigma 10-20 and the sigma 12-24 (note this is a full frame lens and quite big)
