Canon RF 10-20mm f4 L IS STM

I've been shooting handheld in tight interiors, and the 10-20mm range lets me capture everything in a single frame without stepping back—plus it's surprisingly lightweight for an L lens. The f4 aperture keeps things sharp even in dim lighting, and the STM motor focuses silently during video.

The image stabilization is a lifesaver for vlogging—I was walking and filming at 12mm and the footage stayed butter smooth. It’s also shockingly light for an f4 ultra-wide, so I don’t dread carrying it on the R5 II all day.

Shot handheld interiors at 10mm and the corners stayed sharp even wide open at f4 — the stabilisation really earns its keep in low light. Zoom ring is smooth and the lens feels lighter than my old ultrawide despite the L build.
