Hello,
Has anyone tried the latest edition of this lens? I have the older version and I found it quite good but then I was shooting mostly at f16 which is about a stop above it's sweet spot if memory serves me. At the time i bought it Canon didn't have a long zoom but that has been resolved with the 100-400. I would appreciate your thoughts on the lens and/or where there was a test of this lens. Thank you.
Tim
