Analysis of Geometric Distortion 18-70mm versus 18-200mm
Prepared 2005-12-31 (146/46464) by Bill Claff

High zoom lenses such as the 18-200mm with it's 11.1x zoom have a reputation for geometric distortion at either end of their zoom range.

I recently purchased an 18-200mm f/3.5-5.6 G ED-IF AF-S VR DX Zoom-Nikkor and wanted to see how it compares with the 18-70mm f/3.5-4.5G ED-IF AF-S DX Zoom Nikkor regarding geometric distortion.

I want to get these three images posted today and will append a couple more and additional description shortly.
