محول تيليكونفيرتر سيغما TC-2011 2x لتركيب L-Mount

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.

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.

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.
