Great Blue Herons Pt.II (2 photos)
So many birds, and so tame.... I'm very jealous!
My Sigma 400 f/5.6 APO (manual focus) is surprisingly sharp for an under 300 $ lens. It even works respectably with a TC. Manual focus is very OK for stationary birds, and i've got some nice BIFs using CIF. I can live with the little PF that shows up at high contrast.
(Don't get me wrong, of course I'd rather have the Sigma 500 F/4.5, but it costs 15 times more!)
