Canon RF 10-20mm f/4 L IS STM 鏡頭

Finally an ultra-wide that’s sharp across the frame even at f/4, and the IS is a lifesaver for handheld interior shots. I’m genuinely impressed with how light it feels for an L-series lens—definitely makes long hikes more comfortable.

Shooting interiors in tight spaces used to be a struggle, but this lens has completely changed how I work. The L-series build feels solid, and the image stabilization is a lifesaver for handheld shots in dim rooms. Even wide open at f/4, the corners stay impressively clean.

I was blown away by how sharp this lens stays all the way to the 10mm edge, even wide open at f/4—it's made my real estate interiors look dramatically better. The IS really helps steady my handheld shots in dim churches, and the zoom ring is buttery smooth.
