|This Canon 17-85mm lens is amazing to use, but the "-" between the 17 and 85 signifies it's a zoom lens and NOT appropriate for dental use.|
All lenses for dentistry are macro, except Nikkor lenses (Nikon's subsidiary that makes lenses for Nikon) which call them "Micro".
The brand you choose is important for the camera you use. For instance, if you use a Canon body, use a Canon (or Tamron or Sigma) lens. If you use Nikon, you can use a Nikkor (or Tamron or Sigma) lens. In this post, I'm not going to get into the idea of why I'm not a big fan of using "off brands" of lenses. Buy all from the same brand, so that when something goes wrong, there's no finger pointing by one company to another. Hand it in to the repair center and let them sort it out. It's worth the extra few dollars you'll pay on the equipment. However, here I am going to briefly discuss the type of lens you should use.
Basically, with Nikkor and Canon, there are only a few choices. For Nikkor, you can go with the 85mm or the 105mm. For Canon, you can choose the 60mm or the 100mm (the less expensive of the two 100mm lenses Canon makes is fine). The 60 mm lens is simply too tough to use in dentistry. The lower the number the closer you need to be to the subject and with a 60mm lens, for a shot of just the front teeth, you'll literally be 3 inches from the patient. Not good. The flash will never be in a position to work well. So, for Canon, you've got only one choice, the 100mm lens.
|This Canon EF 100mm f/2.8 Macro USM is a great choice for Canon users. DON'T buy the more expense $1050.00 100mm Canon lens. You don't need it.|
For Nikon, the 105 is an amazing lens, but at almost $1000 I simply cannot recommend it over the way smaller and way lighter 85mm lens , which costs half the price. In case you're wondering, photo quality doesn't suffer at all. I've shot both and can't tell the difference in ANY use of the image.
|This AF-S DX Micro Nikkor 85mm f/3.5G ED VR is an amazing lens at a great price for Nikon users.|

Don't go crazy on this subject, but also don;t fall victim to buying the wrong equipment. As I said, I have DVDs to walk you through the entire process of buying, setting up and using your camera, flash and lens for maximum effectiveness, and minimal problems found HERE.
As always, I'm here for you should you have any questions or problems.
