عدسة Canon RF 600mm f/4L IS USM

The autofocus locks onto birds in flight faster than I expected, even in dim early morning light. It’s heavy but the image stabilization makes handheld shots surprisingly steady.

I’ve been using this for sports photography, and the image stabilization is shockingly good—it lets me shoot handheld at 1/60th without any blur. The build quality feels solid, and the focus ring is smooth and precise.

The autofocus is so fast I caught a bird in mid-flight on my first try, and the image stabilization makes handheld shooting at 600mm feel almost steady. The build is solid enough that I don't worry about it in light rain, and the compression at f/4 is gorgeous.
