Tamron 24-70 f/2.8 VC Available for Preorder

[HarryWintergreen]

The trouble with third party lenses is there not being really sharp @2,8. This is exactly what I think the Canon 24-70 f2,8 will deliver: sharpness @2,8 beyond compromises. However, omitting IS is a bit annoying, admitted.

I don't find that to be entirely true. The Sigma 50mm is sharp at f/1.4 and only gets sharper stopped down, unlike the equivalent Canon 50mm f/1.4, which you have to stop down far more to approach the same sharpness. Now these are fixed lenses and the Sigma does have some focusing issues, so it’s not entirely good – but still far better than the Canon. With zoom-lenses the case might be different, but I don’t think it’s a rule. If you look at the review, they state it’s close to “Excellent” even wide open in terms of sharpness.

The Canon 24-70mm II will probably outperform the Tamron, but for twice the price and you probably won’t get any sharp handheld images with a 1/10 shutter speed. The review states that you can get about 50 % sharp photos at that shutter speed with the Tamron.
