ownership:I own this lens
compared to:KM 18-70 f 3.5-5.6 (kit lens)
price paid:260 € (as new)
positive:Very low distortion, very sharp from f 5.6, nice colours, quick AF, lightweight
negative:AF sometimes a little undecided in low light conditions
comment:A great wide angle for outdoor use. At similar apertures, it is significantly better than the kit lens, by a bit in the center but by much (!) at the borders and in the corners. Amazingly little barrel distortion (although there is still some if you really look for it). Colours and contrast are similar to other Minolta primes (e.g. 50 f 1.7). Combine these three properties and you have a brillant lens for landscapes. Sharpness decreases at large apertures but is still OK. In low light the AF needs to be checked as it may focus somewhat differently in two identical shots (on my 5D). I have no problems with the MF ring.
