Canon RF-S 55-210mm f5-7.1 IS STM

My dog gets really excited when I pull this lens out because she knows we're going for a run in the park—the autofocus locks on her face every time. It's sharp enough even at 210mm to catch her mid-sprint.

Took this on a weekend trip and barely noticed the weight in my bag, which is exactly what I wanted from a telezoom. The 55-210 range covers most of what I shoot, and the IS kept my handheld shots sharp even at the long end.

I've been using this lens for wildlife shots on hikes, and the image stabilization really helps with handheld telephoto shots. It's surprisingly lightweight for a 55-210mm, making it easy to carry around all day.
