مُوسِّع كانون EF 1.4x III مستعمل

The autofocus locks on fast enough for sideline sports even in dull light, and the extra reach on my 70-200 made a real difference for tight shots. Mounted and unmounted it a dozen times, no play or wobble in the connection. The used condition honestly looks like barely a scratch on the barrel.

The glass is squeaky clean and the AF didn't slow down at all on my 300mm f/2.8, which is exactly what I needed for sideline shots. For a used unit, the mounting is tight with no wobble, and my images are still tack sharp wide open.

I’ve been using this extender with my 70-200mm f/2.8 for birding, and the 1.4x focal increase makes a clear difference in reach without noticeably slowing autofocus. The weather-sealing is a nice touch for unpredictable outdoor shoots.
