Sony FE 2x Teleconverter (SEL20TC)

Went out for a quick test shoot and the 2x magnification on my 70-200mm made distant subjects fill the frame like I was standing right there. Autofocus still snapped fast with full lens-camera communication intact, so no frustrating lag. Definitely a keeper for wildlife days.

Used this on a recent birding trip and the autofocus speed surprised me—still snappy even at 2x. The full lens-to-camera communication is a game changer for tracking moving subjects. Definitely a keeper for wildlife.

The weather-sealed build feels solid, and the 2x magnification kept autofocus snappy on my mirrorless body even in low light. I was worried about softness, but the dedicated design clearly preserves image quality better than I expected.
