At a glance: Rare constant f/2 standard zoom for Canon RF full-frame - prime-like light, L-series build.
About this lens
Launched in 2018 alongside Canon's EOS R system, the RF 28-70mm f/2 L USM is a standout standard zoom with a constant f/2 aperture across its entire range - light-gathering and depth-of-field control usually reserved for prime lenses. It effectively replaces a bag of fast primes in one L-series body.

Works with
- Fits all Canon RF-mount full-frame mirrorless bodies (EOS R series) with no adapter

- Designed natively for the RF mount - no adapter required
Best for
This lens is aimed at professionals - wedding, event and portrait photographers - who want the flexibility of a zoom without giving up the shallow depth of field and low-light capability of an f/2 prime. The trade-off is size and weight: at around 1430g with a large 95mm front element, it is a substantial lens that balances best on larger RF bodies and is noticeably heavier than a conventional f/2.8 standard zoom.
Frequently asked questions
Does this lens have image stabilisation?
No. There is no optical IS built into the lens, so it depends on the in-body image stabilisation (IBIS) of your camera. On RF bodies that lack IBIS, mind your shutter speed for handheld shots.
Why is it f/2 and not the usual f/2.8?
Canon designed it as a rare constant f/2 zoom, giving it one extra stop of light and shallower depth of field than a standard f/2.8 zoom - closer to prime-lens performance across 28-70mm.
Can I use it on an APS-C RF-S camera?
Yes. It mounts directly on APS-C bodies such as the EOS R7 and R10, but the crop factor changes the effective field of view to roughly 45-112mm.
What filter size does it take?
It uses large 95mm screw-in filters.
