Sigma 70-200 2.8

[cameraexp]

My wife desperately wants this lens and I would like to surprise her with it. Who has the best price?

DeltaInternational.com is where I got mine for $613... is more expensive now, but still prolly cheapest I've seen. Note: It's a gray market lens... works just as well.

I got mine from Digitalfotoclub.com http://www.digitalfotoclub.com/sc/product-features.asp?id=964589911

Has anyone compared this lens with Canon f4L?
Any side by side tests or reviews? I'm making a
buying decision this week.

Yeah, people compared:

That's the comparison of two canons f/4 and f/2.8

I did a comparison of the Sigma and f/4 today...

At the telephoto end Sigma vs 2.8, the difference in sharpness is similar to that of 4/f L to f/2.8 L

In other words Sigma sucks in sharpness department. If you have enough light to stop it down to f/8, you're not gonna see any difference. I might exchange it for f/4

I'll see
