when you buy canon or nikon lenses you are paying a little more or the name. but you are also buying a better product. sigma, tamron and other third party brands keep their prices low by using inferior raw materials and cutting corners in the manufacturing process. this results in an inferior product.

bottom line.... stick with canon or nikon. its worth the extra money if youre serious about photography.

The 90mm f/2.8 Di Macro is stupidly sharp. It's murderous. It's a bucket of razor blades funneled into an empty lens barrel, and certainly one of the sharpest lenses ever designed for the 35mm format. It aliases on an EOS 50D with stacked 2x extenders. Show me any other lens in the world that can do that and I'll be damned.

This is a very subjective question.

Every manufacturer that makes lenses, even OEM, have some great lenses and some dogs. it really comes down to the specific lens in question.

The Tamron 17-50mm f/2.8, 90mm f/2.8 are great lenses that I have used. Some of the others, not so good.
Nikon, Canon, Sigma all fall under the same umbrella.

The best thing to do is to go out and read as many reviews for a particular lens you can and look at image...

Tamron Lenses are pretty well rated (and yes, get dinged for speed):

Sigma is also really good and more popular

I have heard (as of a few years ago) that Sigma actually started out as an OEM for the branded Canon lenses, so the quality is supposed to be higher.
