tamron 70-200 non vc was crap. ALL sigma 70-200 are crap. I had the 70-200 HSM and they lack contrast and sharpness from 2.8-4.5 at f/5 they wake and then there is no use for them. all that weight and not useable. they are supposed to release a 70-200 sport edition thats worthwhile. the tamron 70-200VC is excellent. vignetting at the longer end. af is a bit slower then the nikon. not as sharp on the 2.8 at the longer end. would benefit from a minor aperture stop down to 3.5 then its gtg. great lens and not because of the price. though the front zoom ring is a pita. screws up my workflow. though if I needed a 70-200 itd probably be it. was considering upgrading to the vr2 but that breathing issue is a big issue
Thank you for the info!!! I got my Tamron today and so far, I'm loving it! I did get the 70-200 Di VC USD newest version so I think it is going to work awesome for me! I just couldn't see splurging for the Nikon when I'm not a pro :/
