All: looking for some good advice concerning the Nikon 18-300mm 3.5-5.6 VR lens. I have kit lenses for my d5xxx series cameras which include 18-55, 55-200, and 55-300, all VR AF-S. Get mixed reviews from DPReview concerning warping @ 18mm & vignetting @ or near 300mm. Used price through CC 499.99. Please let me know what you think. Depending on UHH’s thoughts I may need to cancel my order and stick with the lenses I already have. My only reason for looking at the 18-300 was convenience. I know I’ll get some good info from you’all. Need to know as soon as possible. Thanks.
