Take your camera into a shop and play around with the Sigma lens - get a full head shot of someone at 200mm at f5.6 iso 200 then zoom right in on the preview window on the eyes. Absolutely fantastic iris detail.
I absolutely love mine - like I said, the only gripe I have is if you repeat the above at f2.8 the detail in the iris is lost, but you only notice this when zooming right in - the overall picture isn't noticeable. However, YMMV and you may test one that doesn't front focus that tiny centimetre. It's so negligible on mine, that it isn't even worth sending back to Sigma for correction.
Weight wise, it is a bit of a monster, and the lens will cast a shadow using the built-in camera flash. However, if you're shooting at 1:250 or faster, you can hold it steady enough with the correct pose (elbows dug into the ribs) to not get camera shake.
here's a zoom on an eye of a monkey thingy taken at a zoo @70mm f10 at ISO 1250(!) taken through glass (you can see the window reflection)
