Stella ★★★★★

I was worried about losing image quality with an extender, but the RF 1.4x keeps things sharp even at 1120mm. It clicks on securely and autofocus still works well with my super telephoto lens.

Penelope B. ★★★★★

Took it out with my 800mm on a wildlife shoot and the jump to 1120mm made a huge difference in framing distant birds. The extra reach is solid, and I didn’t notice any lag in autofocus when locking onto moving subjects.

Henry ★★★★★

Used this on my 800mm lens for birds in flight, and the extra reach to 1120mm let me fill the frame without losing sharpness. It locks on tight with no play in the connection. Glad I made the switch.
