I have a big white one Canon EF 100-400mm f/4.5-5.6 L IS USM which to be honest is one of me favourites and hardly comes off, but it's too slow and a little soft at the 400mm end. This new one I can double to 400 and not loose AF. or the speed.. I have also bought some bird feeders so look out soon I may be posting some bird feeding shots
