Conclusion from DxOMark:
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. Read the full review at DxOMark.
