With such a fast F2.0 maximum aperture at all focal lengths, the new Canon RF zoom certainly feels like it’s showcasing the potential of switching to the new RF mount. Given the possibilities for low-light shooting, when switching between primes isn’t ideal, a lens like this is sorely tempting. At a dollar shy of $3,000, though, it is a pricey proposition. Still, it has very impressive optical performance, and when viewed overall, it’s even a slightly better performer than the highly-regarded Canon EF 24-70mm F2.8L II USM. Its appeal is somewhat niche, but if you need a lens like this, there isn’t anything else on the market quite like it.
Photography Blog reviewed the Canon RF 28-70mm f/2L lens for the EOS R system. A lens that’s universally considered being of outstanding optical quality.
From their conclusion:
There’s no getting away from the fact that the new Canon RF 28-70mm f/2 L USM lens is very big, heavy and expensive, but there’s also no getting away from the fact that it’s extremely well-built, fast in terms of the maximum aperture, and capable of delivering superlative image quality.
We’ve seen the Canon RF 28-70mm f/2 L USM described as offering four prime lenses in one, and after using it for an extended period of time, we’d certainly agree with that assessment. Whether using it as 28mm, 35mm, 50mm or 70mm, it delivers tack-sharp images both in the centre and at the edges of the frame, with no need to stop down to get acceptable results. That means that you can shoot at f/2 at any focal length and get buttery-smooth bokeh as a result of the 9-blade aperture and that maximum aperture that is one-stop faster than most zooms of this type. Slight vignetting at wide-open apertures and a little barrel distortion at 28mm are the only real optical issues of note from what is optically an incredible lenses. Read the review…
