The Canon RF 15-35mm f/2.8 Lens: Is It Worth the Price?

If you shoot weddings or events, you’ve likely hit the wall where 24mm just isn’t wide enough. Tight prep rooms, crowded dance floors, and sweeping venue shots demand a true ultra-wide that still works when you move in close.

Coming to you from Shane Long Photography, this practical video reviews the Canon RF 15-35mm f/2.8 L IS USM lens, a wide angle zoom designed specifically for Canon's full frame RF mount cameras. Long breaks down how this lens has significantly changed his wedding photography workflow, especially in tight spaces like bridal suites and crowded reception halls. Compared to his older Canon EF 17-40mm f/4 lens, which he loved for its compact size and affordability, the RF 15-35mm offers sharper images, a brighter aperture of f/2.8, and superior image stabilization. Long also demonstrates the practical difference in framing between 15mm, 24mm, and 35mm, highlighting why that extra width at 15mm is crucial in many situations. If you're considering an upgrade, this comparison alone is worth watching.

Long uses real wedding scenarios to show how the RF 15-35mm performs in everyday conditions. He refers to this lens as his "context lens" because it captures the wider story of the day, including venues, ceremony setups, and large group portraits. He also provides metadata from his recent weddings, revealing that this lens is on his camera about 26% of the time, which underscores its importance. If you're on the fence about investing in such an expensive piece of gear, Long’s usage statistics offer practical reassurance about its real-world value.

Long goes further, covering distortion, sharpness, and flare control, all critical details if you're picky about your final images. He shows unedited photos to demonstrate how minimal the distortion is, especially once corrections are applied in Lightroom. Sharpness comparisons with prime lenses at both 15mm and 35mm confirm that the RF 15-35mm lens holds up remarkably well, even wide open at f/2.8. If you're worried about lens flare ruining group portraits or sunlit scenes, Long shows how well-controlled and contrast-rich the RF lens's performance is, especially compared to the RF 50mm f/1.2.

In terms of physical handling, Long acknowledges the lens is heavier and bulkier than his previous EF lens but emphasizes that he quickly adapted. He does point out that the zoom ring is slightly tight, though it loosens up with use. He also notes that while the lens hood is included, he often removes it for flash photography at wider focal lengths to avoid casting shadows. Check out the video above for the full rundown from Long.
