キヤノン RF 400mm f2.8 L IS USM

I’ve been shooting birds at dawn for two weeks straight and the autofocus just locks on every time, even in low light. The weight is manageable for a lens this size, and the image stabilization makes handheld shots surprisingly sharp.

The f2.8 aperture is a game changer for indoor sports — I can finally keep the shutter speed high without pushing ISO past 3200. Autofocus locks onto a sprinter's face instantly, even at 400mm. It's heavy, but the image quality makes the backache worth it.

Shot a full day of ospreys diving at the lake and the autofocus locked on every single time, even against the water glare. The wide f2.8 aperture keeps backgrounds creamy while the bird stays tack sharp, which is exactly what I needed for sports sidelines too.
