Quirky, but worth it, November 7, 2005 By Timothy J. Joko-Veltman "Tim" (Brasilia, Brazil) - See all my reviews This review is from: Sigma 105mm f/2.8 EX DG Medium Telephoto Macro Lens for Canon SLR Cameras (Electronics) When I first started looking for a mid-level macro lens, a few weeks ago, I was naturally drawn first to the Canon 60mm, as I have already have 2 Canon bodies.
But then I started looking around, reading reviews (mostly on Fred Miranda's site), and comparing prices. The more research I did, the more appealing this lens became. And finally, I decided to go with it.
Here's why:
- The price is similar to the Canon 60mm.
- I already own a Sigma EX-series lens (17-35mm), and really like it. I like the matte finish, and the glass is excellent.
- For some reason I cannot fathom, Canon doesn't include lens hoods with any of the mid-range lenses I looked at. Sigma does.
- The greater focal length means I can stay farther from the subject - minimum focus distance is about 30cm (12in). This is almost always a benefit.
This lens isn't perfect, however, and here's a few caveats you may want to consider before making a... Read more

Worth every penny, May 14, 2006 This review is from: Sigma 105mm f/2.8 EX DG Medium Telephoto Macro Lens for Canon SLR Cameras (Electronics) I've been using this lens for about 3 months now on a Canon EOS-350D and the Canon 5D. It has supurb optics. At f2.8, it is sharp. From f3.0 it takes off and stays sharp up to about f14. The focus mechanism is a little different from most other lenses, but actually I've grown to like it. With a push-pull lock at the end of the lens for manual-auto focus, you can put this thing in manual mode two different ways. If you're focusing in, pull the mechanism and you don't have to worry about the camera trying to change focus and you don't have to take your hand off the lens to find the manual button. Really cool actually, just a little different at first. It is light enough that weight has never been an issue, though it does extend out pretty far when focusing. Focus speed is not as fast and there is a little more motor noise, but this too is never an issue as all my close work is manual focus. As a telephoto, it works very well, but the autofocus speed comes into play here. It... Read more

I upgraded to the Rebel XTi (10 mpixels) for home. I purchased the Sigma ring flash with a Sigma macro lens for the Canon SLR family. If you look at the Lester Dine website this is basically what they sell for a few hundreds dollars more.
I compared the ring flash and lens with the ones offered by Canon and felt that it was worth saving $300 by purchasing the Sigma combo.
The macro lens/ring flash work well for dental purposes. After a little experimentation I discovered that I get the best images by using the aperature priority setting. All settings are used with ISO 400 speed. I set the aperature at 14-16 for intraoral shots. This gives the best depth of field. I also use the operatory light for intraoral shots. I set the aperature to 6 for full face shots.
I use autofocus but set the ratio to 1:2 to 1:3 for intraoral shots. This keeps the autofocus from "hunting". I frame the... Read more
