I loved this lens when I owned it, very nice IQ for what it cost.
Didn't like extending zoom, didn't like rotating focus ring.
Between this and the basic 70-200 f4L.. I don't know what I'd buy... The build on the 70-200L's, focus speed, noise and internal zoom / focus could make it worth the little extra, even with the reduced range.
All that said.. nice shots.
