Suppose i should add it was the first lens i owned when i switched to Nikon, i bought it from ebay for around £400 and boy was that a mistake but to be honest i didnt do my homework and didnt really have a clue about all the different Nikon versions.
It was a really sharp lens but AF was a dog in trying to lock on as it was so slow, once it did get a lock it was just about OK at keeping up but nowhere near anything which came after it, nice contrasty images though.
Only ever tried it under lights once and this was the reason i got shot, it just wouldnt AF in the dark.
