Hi all,
Just found this announcement here - same zoom range as the Tamron.
http://www.optyczne.pl/7378-news-Sigma_ ... S_HSM.html
Weighs in at 2860 g, whereas the Tamron stays just a little below 2 kg.
Is it really that bad at 600mm Erik? I have seen lots of pictures of this lens at 600mm that look rather sharp to me. Check for example the bird pictures of Kristofer Rowe at Flickr.com, taken with a D7100 plus 150-600, most shot at the full 600mm. That combination is exactly what I am looking at too.Well let's hope that the Sigma is sharper at 600mm than the Tamron - that lens should really have been build and sold as a 150-500mm!
