Canon 70-200 2.8 mk2 and sigma 85 1.4. The siggy is pretty well built, focus speed is ok but nothing special, never take it out in the rain either. But....the bokeh is amazing, it's pin sharp even at 1.4 it's excellent. You get very very creative blowing foreground and backgrounds.
The Canon? Well what can I say. I took it out yesterday for its first outing. It was attached to a 1d4. It's built like a tank but from the outside looks identical to the old one. Focus speed was immediate on the 4, never used a lens this quick. The sharpness is utterly amazing, even wide open. Then the heavens opened. I'm talking monsoon like rain. All the other photographers with none pro bodies, dozens of em, scurried of to find cover and watch one lone wet photographer standing in the street with a long white lens. Very funny. The 200 never missed a beat. It got drenched for an hour and worked perfectly. So I tested the claimed four stops. Well. I took some shots, hand held 200 mm at a 60th in the rain and got a lot of keepers.
One amazing lens.
