Deco Photo 500MM 預設望遠鏡頭 T-Mount 適配 Canon 相機

I've been using this 500mm f/8 lens for bird photography and the multi-coated optics really cut down on flare, giving me crisp shots even in harsh midday light.

Heavy isn’t the word—it’s solid, that’s for sure, and the aluminum build feels like it’ll survive a hike. The f/8 fixed aperture means you’re chasing light, but on a sunny day the 500mm reach is genuinely impressive for the price. I’d pack a tripod, though; handheld shots get shaky fast.

I've been using this preset telephoto lens for bird photography and the f/8 fixed aperture actually works great in good daylight—just have to remember to focus manually. The lightweight aluminum alloy makes it easy to carry on hikes without getting tired.
