any one been looking out for this lens? been looking at samples and i have to admit it's been exceeding my expectations

saw these couple sample pages:

http://lcap.tistory.com/entry/Sigma-...r-600mm-f56-ED

second link it's comparing to nikkor 600 f5.6 PRIME and beating it...both lenses wide open the sigma actually looks better than the nikkor...amazing

i can't wait for comparison to the new canon 100-400L II that's just announced...may have the potential to make the canon look overpriced, also very interested in comparison to sigma's own 120-300 f2.8 sport + 2x tc

been wanting a "budget" wildlife/birding lens for a while...if all goes well this may be it
