The Canon RF 100mm f/2.8L Macro IS USM and the Nikon Z MC 105mm f/2.8 VR S are close cousins: both are short telephoto macro lenses with an f/2.8 aperture and built-in stabilization. They are made for different mounts, so the practical decision is the camera system you use. Confirm exact specifications on each maker’s page.

What These Lenses Are For
A 100mm class macro lens does two jobs. It lets you shoot small subjects such as flowers, insects, jewelry, and product details at close range, and it also works as a short telephoto for portraits. The working distance, meaning the gap between the front of the lens and the subject, is long enough that you do not crowd skittish insects or block your own light.
Key Differences
| Trait | Canon RF 100mm | Nikon Z MC 105mm |
|---|---|---|
| Mount | Canon RF | Nikon Z |
| Focal length | 100mm | 105mm |
| Aperture | f/2.8 | f/2.8 |
| Stabilization | Optical, built in | Optical, built in |
| Intended use | Macro and portraits | Macro and portraits |
Look at each maker’s page for maximum magnification, minimum focus distance, and any special controls. Macro lenses vary in how they present magnification, and some offer extra features for close work that others do not.
Getting Good Macro Results
- Use a tripod or a firm support when you can. At high magnification, tiny movements become large.
- Choose an aperture around f/8 to f/11 as a general guide for more depth of field, and expect a slower shutter speed as a result.
- Focus manually for the most control, or use focus peaking if your camera offers it.
- Add light. A small flash or a continuous panel lets you keep a faster shutter speed and a lower ISO.
- Consider focus stacking for subjects that need more depth than a single frame can give.
Choosing Between Them
If you own a Canon RF body, the Canon is the natural choice. If you own a Nikon Z body, the Nikon is. Adapting across brands is rarely practical for modern mirrorless lenses. If you have not bought a camera yet, compare the systems as a whole, including other lenses you may want later, rather than judging by one macro lens.
If you are undecided, think about the lenses that will surround this one. A macro lens is often the first of several purchases, and what the system offers in portrait primes, telephoto zooms, and flash accessories may matter more over several years than small differences between two similar macro lenses.
FAQ
Can a macro lens be used for portraits?
Yes. A 100mm focal length is a popular portrait range, and the f/2.8 aperture gives a pleasing background blur, though extreme sharpness at close range may be more than some portrait subjects need.
Do I need a tripod for macro?
It is strongly recommended for precise framing, although in-lens stabilization helps when handholding.
The Short Version
These lenses are alike in purpose, so choose the one made for your camera mount. Choose the Canon for RF bodies and the Nikon for Z bodies, then check each maker’s page for magnification and focus details. We have not used either lens ourselves.
