Well, that lenstip review did mention quite heavy coma (worse than the Zeiss and Nikon wide open). So maybe what you see is normal <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/blink.gif' class='bbc_emoticon' alt=':blink:' />

It might be normal, yes. However, I'd like to be sure. That's why I contacted Sigma.

What's puzzling is that the MTF values actually drop (!) from f/1.4 to f/2.8 and then recover again. They chart looks really strange ...
