Ok, any thoughts on which is better. To my surprise the sigma is listed as more expensive by about 20 dollars CAD. So, anybody got any persuading advice about either of them?
Basically looking for a good macro lens, I have about 4-500 dollars (Canadian) to spend. Also, I have set of EF extension tubes that I would like to put to use (my EF-S 17-85 won't work with them). Thanks.

Well the huge difference is that the Sigma can go to 1:1 magnification, the Canon can't (1:2) without a lifesize converter ($250ish). The Sigma also has an EX designation which means it's a pro lens. If you were choosing between those two, I'd go with the Sigma. You can also look into the Canon 60mm macro or the 100mm macro. I'm not sure how much 400-500 canadian is though...

How would each compare in sharpness would you say?

If you can afford it, I'd definitely go with the Canon 100mm f/2.8 macro. Awesome lens!! You will not regret it.
Here is a pic with this lens. Amazing sharpness.

They're probably about the same as far as sharpness goes, but the Sigma should have a better build quality (don't quote me on that though) since it's an EX lens. And of course, as I said before, the 1:1 is huge and definitely a must have when you're looking for a macro lens. The Canon needs the $250 life size converter which already puts you at $500 so you might as well buy the Canon 100mm macro at that point. If it were up to me, I'd get the Sigma for the life size magnification. You've actually got me thinking about seriously getting one now too...
Edit to add: The Sigma also comes with a case and a lens hood whereas the Canon doesn't come with either.

I've been using that Sigma lens for a couple of years and am very happy with it. But there's a brand new Sigma 70mm f2.8 EX DG macro that I'd suggest you look at first. It's reviewed in the December issue of Popular Photography with this conclusion: "With a lens like this, Sigma makes it difficult for us to sound objective. In practical terms, it's faultless." They also think it's the sharpest lens currently made by Sigma. Street price USD430.
Personally, I'd prefer 70mm to 50mm anyway, because at 1:1 on a 50mm lens you are so close to your subject (like an inch away) that it's very difficult not to cast a shadow on the subject. |
