What's the best lens for dental photography?

A 100mm macro lens with 1:1 magnification is the most recommended: it records the tooth at true size and keeps you at a comfortable distance from the patient.

Ring flash or twin flash?

A ring flash is easier and gives even light; a twin flash shows the tooth's texture and shape better, especially for front teeth.

What settings should I start with?

Manual mode, ISO 100, f/8 to f/11, white balance on flash, then adjust the flash power.

Do I need an expensive camera for dental photography?

No. Dental photography uses only a few camera features, so the brand matters less than you'd think. What you need is three right pieces: a camera, a macro lens and a flash made for close-up work. A mirrorless body is lighter in the hand, which helps when you shoot many cases a day.

What else do I need besides the lens and the flash?

Four clinic tools complete the picture. Cheek retractors hold the lips and cheeks back so the light and the lens can reach the teeth. Intraoral mirrors show chewing surfaces and hidden areas; warm the mirror first so it doesn't fog. A black contraster behind the tooth shows its edge and translucency. A cross-polarising filter with a grey card cuts the shine so the tooth's colour reads truer when you match the shade. Your dental supplier carries these.

How to update

Download the lens firmware from Canon's page (button below). It has the firmware file (RF049110.afu) and Canon's own update instructions (PDF).
Format (initialise) a memory card in the camera, then copy the firmware file to the top level of the card with a card reader.
Remove any extender from the lens. Put the card in a compatible EOS R camera, mount the lens, turn the camera on and set the shooting mode to P, Tv, Av or M.
Press MENU, choose [Firmware Ver.X.X.X] in the Set-up tab, select [Lens], then [OK], and follow the screen.
Use a fully charged battery or Canon's AC adapter. During the update don't turn the camera off, open the card slot cover, press any buttons or remove the lens.
When it is done, turn the camera off, take the battery out, wait at least two seconds, put it back and turn the camera on. Format the card before you use it again.
