First Sigma 150mm F2.8 shots

Well, testing the Sigma 150mm F2.8 AF IF EX DG APO MACRO HSM lens. Sigma marketing must have a poll on who can invent the longest acronym list!

Anyway, here are some samples. I already noticed a few things:
- Macro photography is HARD .. but since the lens will be used mainly for portrait stuff, I can get around that ;-)
- AF is, even though it is an HSM lens, quite slow. AF tracking is hit or miss, even if you use the focus limiter.
- The damn thing is heavy. My D700+MB10+8xAA is already pretty weighty.. adding the 150mm doesn't make it easier. The whole kit weighs 2.6kg .. 
- Sharpness and field flatness is excellent.. I wonder if I could use this lens for piggyback astrophotography.

Any vignetting you see is added in post-processing :-)
