Canon Extender RF 1.4X

The smart-connect design made mounting it on my lens effortless, and the extra reach it gives without sacrificing image quality is impressive. Autofocus stays snappy even with the f-stop loss, which was my biggest worry.

Finally got to test this with my 100-500mm lens and the autofocus is still snappy even in low light. The extra reach makes birding so much easier without carrying a bigger lens.

Picked up the RF 1.4x extender for wildlife shots, and the extra reach on my 100-500mm is exactly what I needed. Image quality stays sharp, and the smart-connect mount locks on securely without any play. Really glad I went for this over a cheaper third-party option.
