二手 Opteka 500mm f6.3 DG 反射鏡 - Canon

For the price and weight, this 500mm mirror lens is a steal—I’ve been getting crisp shots of birds at the park without needing a tripod. The compact build makes it easy to carry on hikes too.

The manual focus took a bit of practice, but once I got the hang of it, this lens captures incredible detail on distant subjects. It's surprisingly light for a 500mm, making it easy to hand-hold during long sessions.

I’ve been shooting birds in my backyard and the compact size makes it easy to hand-hold all afternoon. The 500mm reach really pulls in distant subjects, though I wish the focus ring was a bit stiffer—still, for a used bargain, it’s hard to beat.
