Sigma 70- 200 2.8

Hi folks,
I am thinking about buying the above lense for my EOS 400d what are your thoughts on this lense. and also the 2x convertor any info would be great

Thanx Goggs

The 70-200 is one of Sigma's best in my opinion. It compares very well to the Canon version. AF speed is fast, it's sharp wide open, and built very well. I don't care for the warmer color rendition of Sigma's anymore but that would be my only gripe. Canon's 70-200 is a bit sharper at 200, Sigma's 70-200 is a bit sharper at 70.

I am not a fan of 2X convertors at all and don't think they belong anywhere, ESPECIALLY on a zoom lens.

Agreed. But that Sigma does takes a 1.4x convertor very well, with little or no noticeable loss in IQ. It's an excellent alternative to the Canon that you can find for the price of the 70-200 f4.

Thanx for the info guys that is a great help

its true about warmer pics, nothing that can't be fixed in pp if you like. It's a great lens really. I had it once went to the f4 from canon in same range and eventually came back to it. really fast to focus, sharp even wide open, some pp needed of course. great buy imho

Same here. Great lens. I havent had a chance to try it with a tc though, i want to.
