Tyler Vargo said:I'd go with the Canon in this one, it is $630 cheaper, has IS, USM and is an L lens to boot (the best glass Canon makes!). I've seen awesome images taken with both but strongly suggest the 100-400L, you'll get more "bang for your buck".

stuartlawrie said:Interesting, I wondered why the Sigma was now dearer, I have the old Sigma 50-500 and have recently acquired the Canon 100-400, I have to say I can't see a lot in them other than the extra focal length, I know the IS is supposed to help but to be honest I still ain't had any results that impress me that greatly over the Sigma which I have been shooting with for over two years with both here and in Kenya. unfortunately the Sigma is in being repaired at present as I was unfortunate enough to have it blown over a few weeks back, but despite having it replaced by the Canon, I am paying to have it repaired.
Only one thing with the Sigma, get pumping those weights, carrying it for any length of time is more exhausting than the Canon
Kevin Bates said:I use both these lenses, my preference is the Sigma 50-500 it has a better range and is more suited to bird photography, checkout my gallery to compare the two.
Gwynn said:I went for the canon last year and I am very happy with it, but I would be intested to know how good that NEW sigma lens is it isn't even listed on most of the websites I have looked at, just the old 50-500 one is on them
Gwynn said:Hi Romy, was that test done with the old 50-500 or the new one?

Romy Ocon said:Hmmm... very interesting. ExpressCamera listed two Bigmas - the old one at USD 759 and the "Pro" one at USD 1899. I'm curious at what they did to the lens to justify a 150% increase in price, having no OS yet anyway.
Looking forward to impressions of early buyers. If the new Pro Bigma can approximate the picture quality of the 500 f/4 (but at f/6.3), then the new price is a bargain even without OS or IS.
Cheers,
Romy

IMHO, the Bigma has a good performance-cost ratio, a fine interim lens until one can afford the Canon Big Whites.
I now carry two systems in the field - the 400 5.6L + 20D for flight shots, and the 100-400 L IS + 300D for hand held shots in lower light. I hope that someday, I can afford my ultimate dream lens for birding - 500 f/4 L IS.
Cheers,
Romy
