Canon RF 70-200mm F2.8 L IS USM Z Review: An Internal Zoom and Teleconverter Support Fix the Original's Flaws

Canon’s first RF 70-200mm f/2.8 was compact and very sharp. It also extended as you zoomed and couldn’t take Canon’s teleconverters, two things that bothered pros. The Canon RF 70-200mm F2.8 L IS USM Z, announced in October 2024 at $2,999, fixes both. It zooms internally, it works with the RF 1.4x and 2x extenders, and the “Z” means it’s ready for Canon’s optional power-zoom adapter.

That last feature tells you who it’s for. This is a lens for stills pros and video crews alike.

It weighs about 1,110 grams in black, and it comes in Canon’s classic white as well.

What the internal zoom gives you

The lens stays the same length at every focal length. Balance never shifts, so it’s easier to handle on a monopod, a gimbal or a tripod. Dust and moisture have fewer ways in. And for video, zooming doesn’t change how the rig sits.

With the RF 1.4x extender it becomes a 98-280mm f/4. With the 2x it becomes a 140-400mm f/5.6. For event shooters who also cover sport or wildlife, that’s two lenses in one bag slot.

Optics and handling

Sharpness is excellent from f/2.8 across the range, with smooth backgrounds from 11 aperture blades. Close focus is 0.68 meters at 200mm, for 0.3x magnification.

Dual Nano USM motors focus quickly and quietly, keeping up with the R5 Mark II, R6 Mark III and R1 at full burst speed. Optical stabilization is rated at 5.5 stops, or up to 7.5 with in-body stabilization.

There’s a de-clicked aperture ring, which few Canon lenses have, plus a control ring and two configurable function buttons. The lens is fully weather sealed.

The optional PZ-E2 power-zoom adapter attaches to the side for smooth, motorized zooms in video.

The tradeoffs

Price, at $2,999, is high even for an L lens. The original RF 70-200mm f/2.8 is cheaper and smaller when retracted.

The internal-zoom design makes it longer and heavier than the original at its shortest. If you pack tightly, you’ll notice.

Third-party alternatives on RF are still limited at this level.

Who should buy it

Canon wedding, event and sports photographers. Video crews who want a power-zoom-ready telephoto. Anyone who wants 70-200mm and 140-400mm from one lens with extenders.

If you value compact size over internal zoom and teleconverter support, the original RF 70-200mm f/2.8 remains a great lens and a better travel option. For working pros, the Z version is the one to buy now.
