Canon RF 100-500mm F4.5-7.1 L IS USM

I’ve been shooting birds at dawn with this lens, and the autofocus locks onto fast-moving subjects instantly even in low light. The zoom ring is buttery smooth, and the build feels rock solid after a rainy morning out.

The 5-stop image stabilization is a lifesaver for handheld shots at 500mm—crisp images every time. Build feels solid and weather-sealed, exactly what I needed for outdoor shoots.

I was worried about the variable aperture in low light, but the image stabilization is so effective that I'm getting sharp shots at 500mm handheld. The zoom ring tension is also perfectly damped, making adjustments feel precise and smooth.
