Title: Very disappointing
Review: I know you can't get something for nothing -- and I guess I forgot that when I ordered the Tamron 18-200 for my Nikon D70. It seems like a great idea -- but one must remember that a super zoom must make many trade-offs. My first bad experience was trying to put two Tiffen filters on. At 18mm it created a black shadow on the sensor. I then started noticing the lack of sharpness and distortion compared to the stock Nikon 18-70 lens. For most of my shots, it probably is OK. But when one counts -- I don't think it will deliver.
