Sebastian ★★★★★ Oct 21, 2026

Took my 70-200mm out for birding today and the autofocus kept up perfectly even with the 2x magnification. The metal mount feels solid and the lens communication is seamless—no guesswork in exposure.

John ★★★★★ Oct 20, 2026

I was worried about losing image quality with a 2x converter, but autofocus on my 85mm is still snappy and sharp enough for portraits. The full electronic communication is a huge plus for me.

Owen B. ★★★★★ Oct 19, 2026

Shot my 70-200mm at a local airshow and the autofocus stayed locked through the full 2x magnification, even on fast-moving jets. The metal mount feels rock-solid on the camera, and image quality holds up better than I expected for a teleconverter.
