|comment:||This is my second teleprime. I had a Sigma 400 5.6 non APO that stipped gears after the second time in my A100. That one was only sharp by f11, the Telemacro is sharp wide open and super sharp by f8. The build quality is also a lot better.|
I'm in love with the focus ring in this lens. The Limit switch speeds up focus a lot and is well implemented. I've never seen a Sigma lens with such an accurate focus.
Compared to the tamron or the canon the sigma gains in sharpness at 400mm but losses in versatility.
So far I've not seen any PF and flare seems well controlled.
1.6m MDF for a 400mm prime is amazing.
