A compact, lightweight wide angle zoom can change the way you shoot landscapes, travel, and even video. The Canon RF 16-28mm f/2.8 offers a versatile range while keeping things small and manageable. But does it hold up against Canon’s more expensive L series options?
Coming to you from James Reader, this thorough video looks at the RF 16-28mm f/2.8 IS STM in a variety of real-world shooting conditions. It’s a small, light lens that covers an extremely useful focal range for landscapes, architecture, and video work. Compared to the heavier, more expensive RF 15-35mm f/2.8L, the 16-28mm trades some range and build quality for a more portable package. Reader examines whether those trade-offs matter and if this lens can keep up optically.
Sharpness is a major concern with any wide angle zoom. Reader puts the 16-28mm up against the 15-35mm f/2.8L and several prime lenses to see how it performs at different focal lengths. It holds up surprisingly well, especially in central sharpness, sometimes even surpassing the L series zoom. Corner sharpness varies—sometimes the L lens has the edge, other times the 16-28mm does. At f/8, the differences mostly disappear, making it a compelling choice for landscape photographers who frequently shoot at smaller apertures. The biggest optical compromise comes from its reliance on digital corrections for distortion and vignetting, particularly at 16mm.
The RF 16-28mm also performs well in autofocus tests. Despite using STM motors instead of the USM motors found in Canon’s L series lenses, it focuses quickly and accurately. Subject tracking remains reliable in both photo and video modes. In handheld video work, its optical stabilization pairs well with in-body stabilization to produce smooth footage, making it a strong choice for vloggers and hybrid shooters. Compared to the 15-35mm, its stabilization may even be slightly more effective.
The lens’ biggest appeal is its size and weight. Weighing in at just 445 grams, it’s a fraction of the 15-35mm’s heft. For travel, handheld video, or anyone who prioritizes portability, this is a major advantage. However, it does have a retracting mechanism similar to the RF 28-70mm f/2.8, meaning it needs to be extended to 16mm before it can be used. Some may find this inconvenient, but it helps keep the lens compact when stored. The lack of a dedicated focus ring might be a downside for manual focus users, though most shooters likely won’t miss it. Check out the video above for the full rundown from Reader.
