I'm in the market for a new lens for my D100. Lenses in the focal length and speed range I want range in price from $320 to $1450, and vary over a 2:1 weight ratio. I just read a very strong review of the cheapest and lightest of them by our own Bob Atkins. (N.B. I already have another thread on that topic so THIS is a different question . . . ) Bob only appears to only review Canon, and Canon-mount lenses. And PhotoDo is no longer publishing new work. My question is: is there ANYPLACE that does good, objective lens testing of a variety of lenses, so when you're in the market for a lens and you want to know if a lens that costs 4X as much and weighs 2X as much as another lens is worth it, you can find out?
