二手 Canon EF 70-210mm f4 鏡頭

I was worried buying used, but this zoom is in great shape and the constant f4 really helps when I’m shooting outdoors in changing light. The focus ring turns smoothly, and the glass looks clean.

The zoom ring is buttery smooth for a lens that's been around the block, and that constant f/4 held up nicely even at 210mm in overcast light. It's clearly used, but the glass is clean and the autofocus locks on without hunting. Solid workhorse for the price.

The constant f/4 aperture across the whole zoom range is such a relief—I never have to worry about the shot getting darker as I pull in closer. This used copy arrived clean, and the focus ring turns buttery smooth, which makes manual adjustments feel really precise.
