二手 Canon EF 2x 增距鏡 Mark II

I needed extra reach for bird photography without buying a new lens and this extender does exactly that, doubling my focal length perfectly. The build quality feels solid and the glass is in great shape for a used item, no scratches I can see. Autofocus is a tad slower but still reliable, so I'm hap

Mounting this on my 70-200mm with the mark III firmware was seamless, and autofocus is still snappy even with the 2x multiplier. The glass looks clean with no haze, and it’s built like a tank.

I was nervous buying used, but this extender arrived looking almost new; the glass is spotless and the mount is tight. It doubled the reach of my 100-400mm perfectly for wildlife, and image quality is still sharp. A solid buy for the price.
