I use the Canon 100mm macro lens and love it. It is a versatile lens. At times I've paired it with an Canon extension tube for certain macros. I don't have experience with the Sigma, but have not heard much good about older Sigma lenses with the Canon electronics. If you want some examples of the 100mm, there are some recent images in my portfolio.
Trusting that you can see the quality of the lens despite my clumsiness as a photographer, that might give you some idea of what the lens can do. There are other photographers on this site that also use the Canon 100mm macro that do a much nicer job with it.

If you buy a set of extension tubes (they're not very expensive, either), you can take macros even with a 50mm lens, because you'll be able to focus from as close as a couple of centimeters. Mind you, the DOF will be razor thin. I used to use a Sigma 70-300mm Macro (with an EOS 500) for macros, but even in macro mode I did not get a better close-up than with the 50mm w/ext. tubes.

Hi,
Sigma make a 105mm 1:1 macro, meant to be equivalent to the Canon 100mm. Though I've not used either I've heard a lot of very good things about this lens and while everyone seems to agree it's not quite as good as the Canon (which everyone says is awesome), it's supposed to be very close for less cash.

I have recently purchased a canon 100mm macro lens and can say it is is extremely sharp and also very fast to focus regardless of the subject distance. I did try prior to recieving this lens the sigma but there seemed to be a conflict with the 10d and showed and error message on the display screen, so sent it back. I know that the canon lens is quite expensive but in my view is well worth it. i have so far posted one macro shot if you feel you would like to see its capabilities. Should this lens be out of your reach, then a more appropriate alternative than the sigma would be the tamaron, which is considered to be quite sharp.

I read somewhere on the net, that Canon doesn't like Sigma making lens's for Canon cameras (and who would want someone else making lens's for their products??), but I contacted Sigma on this, and they told me via e-mail that (this is concerning the sigma 28-300 by the way), the serial number starts with a 1, or a 2 - it will need to be re-chipped (the lens), if it starts with a '3', then it should be fine. Not sure if that helps or not. I ordered the 10D, and the Sigma 28-300, and I haven't recieved iether yet - but should be in next week!!! (I CANT wait!)

I purchased the Sigma 50mm Macro EX and the Sigma 105mm Marco EX from Adorama. Before the lenses shipped I requested the serial numbers through e-mail and then contacted Sigma. After 2,000 plus photos and four weeks I have not had a single issue with compatibility with my 10D. In my research prior to buying, many forum participants on other sites reported issues with older Sigma lenses, but I have been very pleased with the results of my new Sigma macro lenses. I'm fairly new to this site and far from a "great & experienced" photographer, but most of the photos that I have posted were taken with the 50mm macro lens. Good luck in your search.

I recently purchased a Sigma 28-300mm for my Digital Rebel (300d). It's serial number starts with a 1. Will I need to have this rechipped? How do I go about getting this done?
