i had this lens and i did some comparison shots against some primes namely the 24 2.8 sigma, 28 2.8 canon and the 50 1.8 canon. Shots were taken with tripod and fixed focal point, lighting etc. Ran this test twice with an independent checker. lolz ...... i must say i was very impressed with the results of this cheap light lens. Infact i sent some shots to a wide-angle `specialist' and he too confirm my findings. Too much to discuss here but all i would say is if you are looking for a cheap, light and portable lens, this is it. Infact i let some Csers try out this lens and generally most are happy with its VFM (value for money) factor. then again its only a 0.02 cts newbie's opinion!! ............... t :bigeyes: m
