[QUOTE="DraganDL, post: 286134, member: 18251"] Heavy "barrel" distortion, that amounts to 3.67% at 18mm (for the sake of comparison, Nikon 18-135mm distorts up to 3.35% at the same focal length). Take a look at this ("real photo") example and the laboratory analysis: [URL="http://goo.gl/vUCBWx"]Nikkor AF-S DX 18-300mm f/3.5-5.6 G ED VR - Review / Test Report - Analysis[/URL] :friendly_wink: Now, compare it to 16-85mm (yeah, I know it's range is way too narrower, but that's exactly the point - to avoid such "extremes" or not) [B]probably the best Nikon DX all-around zoom ever[/B]: [URL]http://goo.gl/g5wRqK[/URL] At 16mm it produces significantly lower amount of distortion than either of these at 18mm (!): 18-55mm, 18-70mm, 18-105mm, 18-135mm, 18-140mm, 18-200mm, 18-300mm. But, the quality comes at a price... [/QUOTE]
