[QUOTE="aroy, post: 342910, member: 16090"] I have the AF version and it is very bad - lots of CA, and soft at the long end. Regarding AF vs AF-S. For the AF lenses, speed mostly depends on the body, so in some cases the AF may be much faster, where as AF-S has constant speed irrespective of the body. Another thing to check is the optical performance. In most of the cases AF-S versions have better optical performance compared to older versions. One exception that I know of is the 50mm F1.8. The AF/AFD versions have lower distortion and CA, but AF-S is a tad sharper. [/QUOTE]
