photosoup guru said:There are only two differences between that lens and the $300 ED lens... the mount is plastic and it doesn't have an aperture ring. Other than that supposidly, everything else is the same. Maybe sloppier mechanics, and the manual focus ring is too sensitive.... I got one off ebay for $80..
If there is a lens that is the same but better made, I would never go for the badly/less good made!
