Focal Range

Canon RF 28-70mm F2L USM has a focal range of 28-70mm and 2.5X zoom ratio. When it is mounted on an APS-C sensor camera with 1.6x crop, it provides an 35mm (FF) equivalent of 44.8 - 112mm.



Weather Sealings

The Canon RF 28-70mm F2L USM is a weather-sealed lens, which provides extra protection to prevent water and dust get inside the lens and camera body under light rain, snow and wind. In order to have effective protection, you have to pair the Canon RF 28-70mm F2L USM with a weather-sealed camera body such as the Canon R8, Canon R6 II and Canon R7.

Optical Image Stabilization

Canon RF 28-70mm F2L USM doesn't have an optical image stabilization system so the only option to stabilize the image taken with this lens is to mount on a camera body with IBIS (sensor based In-body image stabilization).

Alternatively, you can check the Canon RF 24-70mm F2.8L IS USM in Canon RF mount that have similar focal range but features Optical Image Stabilization.

Zoom Method

Canon RF 28-70mm F2L USM features Rotary (extending) zoom method where the length of the lens changes as you zoom in or out. This makes it possible to design the lens with a smaller minimum length ( generally when it is zoomed out) compared to internal zoom lenses. The disadvantages of this design are being harder to seal against dust and moisture, weight balance shifting while zooming and zoom creep in certain lenses.

Maximum Magnification Ratio

Canon RF 28-70mm F2L USM has a Max Magnification Ratio of 0.18x and has a minimum focusing distance of 0.39m. 0.18x means that the max magnification ratio is very low and not suitable even for modest close-up shots.
