Canon has RF-mount standard zoom lenses coming out of its ears, making it hard to believe the company has only been making mirrorless full-frame EOS R system cameras and lenses since 2019. The net result from a buying perspective is that it can be hard to choose the one that best suits your needs. Pricing aside, which I’ll come back to presently, options range from the super-tiny RF 24-50mm f/4.5-6.3 IS STM, through no less than three different RF 24-105mm zooms, to relatively ‘fast’ RF 24-70mm f/2.8L IS USM and RF 28-70mm f/2L USM lenses.
The new RF 28-70mm F2.8 IS STM caters to those who want a constant f/2.8 aperture for gaining a tighter depth of field and maintaining fast shutter speeds under low lighting conditions, without suffering the increase in size, weight and expense that this type of lens usually entails. Indeed, I’ve been impressed with similar offerings from other manufacturers, including the Nikon Z 28-75mm f/2.8 and Tamron 28-75mm f/2.8 Di III RXD G2, the latter being available for both Nikon Z and Sony E mount cameras. Back in Canon land, the RF 28-70mm aims to be one of the best lenses for Canon EOS R system cameras.
