It will be used as an everyday lens on a Nikon D70. I tried FredMiranda.com, they gave the 24-135 excellent reviews, but do not have anything on the 18-200. TIA

Take that into account for your wide angle end of the range.

18-200 sounds inviting, but I wonder how good it really is. Also, f 1:6.3 for some of the FL settings is not really what you want for an everyday.
