Review on Enhance and Extend Image Quality with Canon EXT. RF1.4X(N) (4113C002) by Jonathan Waritani

Easy to use, produces sharp images, does not affect autofocus performance. The main limitation, not really related to RF1.4x, is that it's compatible with multiple lenses (at the moment) and they're pretty slow. So if you find yourself in low-light situations, losing an extra lens can really increase the noise. levels. But in good conditions this lens is worth its weight in gold. And that's what you're paying for, the price seems a bit overpriced but if you need it that's the entry-level price.
