: > Well??? Tell us the link! Sounds like a very interesting page. OK, here it is, : http://www.usa.canon.com/consumer/controller?act=ProductCatIndexAct&fcatego ryid=151 : : On the left is a window called - "EF Lenses 101" -- Inside this window : is a section titled - "Focal Length Comparison"....... a direct link: http://www.usa.canon.com/app/html/EFLenses101/index.html though it's the standard horrible 'crop the guts out' style comparison :( ..the same as showing one very wide angle shot and then a succession of crops - which is exactly what a longer lens does if one does not move ones feet ;) k
