Dear Sirs,

Would it be possible to get any nice advice what to think about in the process and consideration of the Choice of the New Version II of the Canon Super-Tele-Lenses EF500mm f/4L vs EF600mm?
I am not only a BIF photographer but also would appreciate to do more broadly wildlife photography with ONE of these new super-tele-lenses.
(I happen to already have the old version I of EF300 f/2.8L IS USM and sometimes using it with the Extension Tubes for close-up-flower photography)

And also I rather handhold them for the flexibility of capturing the best available compositions!

I am not a very strongly built fellow but more average built and I can use my 7D with EF 1.4III-300 f/2.8L IS USM handheld quite well.

I would appreciate your input!

Wishing you all a wonderful week-end and nice new shoots!

Charl
