Attention: Struggling to Choose the Right Lens?
If you’re just getting into dental photography, you might be wondering: Which macro lens should I use? There are plenty of options, but the two most common choices are 60mm and 100mm macro lenses. Which one is better for you? Let’s make this simple.
Interest: Why Does Focal Length Matter?
In dental photography, we need sharp, distortion-free images. That’s why macro lenses with 1:1 magnification are ideal. But focal length—measured in millimeters—affects more than just how close you appear to be to the subject. It influences image quality, working distance, and practicality when taking intraoral and portrait shots.
Here’s a quick comparison:
- 60mm Macro Lens: Smaller, lighter, and usually more affordable.
- 100mm Macro Lens: More versatile, better for portraits, and provides more working distance.

Tip: Avoid Zoom Lenses for Dental Photography!
If any salesperson tries to convince you to buy a zoom lens instead of a fixed macro lens (65mm, 90mm, 100mm, or 105mm) with a 1:1 magnification scale, don’t take the bait. Zoom lenses are not suitable for precise dental documentation, as they often lack the sharpness and consistency required for professional photography.
Desire: The 100mm Advantage
While a 60mm lens might seem like a budget-friendly choice, a 100mm lens is a smarter long-term investment. Why?
- Better for Portraits – A 100mm lens reduces facial distortion, making it perfect for capturing realistic patient portraits. Distortion is minimal in the 85-135mm focal range, giving you the most accurate facial proportions for analysis and communication.
- More Working Distance – With a 100mm lens, you don’t have to be uncomfortably close to the patient’s mouth. This extra space improves lighting conditions and minimizes lens fogging caused by breath condensation.
- More Versatility – A 100mm lens allows you to shoot both intraoral and portrait photographs with professional-quality results, making it the best all-around choice for dental professionals.

Tip: APS-C vs. Full Frame – Does Sensor Size Matter?
If you’re still unsure whether to choose a 65mm or 100mm lens, the sensor size of your camera matters.
- For APS-C cameras, a 65mm lens is a great choice.
- For full-frame cameras, a 90mm, 100mm, or 105mm lens will give you better results.
