Verdict

Canon’s RF 28-70 2.8 delivers a step-up over entry-level kit zooms in build, quality and potential bokeh, without the cost or indeed heft of higher-end L lenses. This makes it an ideal option for smaller mid-range full-frame bodies like the EOS R8. But this mid-range positioning also makes it one of the most expensive non-L lenses in the RF series to date, uncomfortably approaching the price of the 24-105mm f4L which for only a little extra gives you a broader zoom range, L build quality, and a lens hood. The 28-70 2.8 of course counters with its brighter f2.8 aperture, a slightly lower price and a barrel that’s smaller and lighter. Physically this makes it a better match for the smaller bodies, but I’d still say the pricing is a bit on the high side.

Ultimately I like the concept of a 28-70 2.8, sacrificing some of the wide-end to come in cheaper than a 24-70 2.8. But while Canon’s costs roughly half that of the 24-70 2.8L, I’d have been happier had it been closer to a grand, especially as Sigma and Tamron can do it for around 800. But as we all know, that’s an academic argument as neither of them make native full-frame lenses for Canon’s EOS R system.

If you’re after a more affordable 2.8 zoom, consider adapting an EF model, whether made by Sigma, Tamron or Canon themselves, with some great prices on used models – check MPB for some ideas. But none will be as small and light as the new RF 28-70 2.8, and most will be slower or noisier at focusing. And to be fair, many of us have been asking for mid-range Canon RF lenses – and with its bright aperture, weather-sealing and price-point the 28-70 2.8 is exactly that, slotting between entry-level and high-end options. So the choice is yours.
