Sigma or Canon?

Hi,

i am looking at getting the 10D (of course) but am somewhat perplexed by which lens to get. i had my mind set on the canon 75-300 f4/5.6 mkIII USM but then somebody said get the sigma lens 70-300 f4/5.6 macro.

any thoughts?

thanks in advance - appreciate it.

I have the Canon 75-300 IS USM and can definately say that it is a great lens- clear, sharp, etc.

Just make sure that the one you purchase is the IS USM version. i use mine on a Canon D60 and have never been disappointed.

hi,

thanks for the info - the IS is like twice the price - how effective is the image stabilizer?

so you would go with canon and not the sigma eh?

thanks in advance.

I have the Canon 100-400L IS lens. I have taken the same subjects with image stabilization on and off and I find that there is a noticeable difference in the image with it on. This was usually at the high end of the focal length. I would definitely recommend the IS.

I've never considered Sigma for lenses. If I was going to invest in a Canon body I decided that I would only use their glass until someone proved me wrong. I'm sure that Sigma makes a good product but I just felt more comfortable staying with Canon glass.

I had bad experience with Sigma:
I've bought a 28-300 and after one week, the aperture stuck in the last shot position. I had to manually push to the depth of field view button and turn the aperture full up and full down to get it back btw each shot.
I've finished my 2 weeks trip like that, and got an exchanged when I was returning to the dealer.
After 2 years, the issue started again with this one, and this time the aperture is stuck at f/11 and I can't move it... just decided to throw it away and stop buying sigma.
I wasn't very pleased with this lens anyway.
will invest on Canon and Tokina (which seems to be pretty good build quality and efficient opticals.
