    I really like this lense, it’s affordable and does great on my R10. It does struggle in low light when paired to my APS-C sensor, but that was expected. This lense does exactly what it is advertised to. No complaints!

    This is a great lens for the price! Works great with the EOS R8 for capturing beautiful pictures of our church’s worship services from the back of our auditorium…about 75 feet away from the people on stage.

    Low price and light weight are the two big plusses. Image quality and sharpness are very good. I had been shooting with on old EF 100-400. This new RF lens is a pleasure to use and it's so much lighter than the old EF 100 to 400. If you buy one, don't forget to unlock the zoom lock switch before trying to zoom.

    Great addition to my Canon R10. Zoom is incredible and the eye focus for animals is a plus. Can't wait to go birding with this lens.

    I bought this lens for my wife. Comparing to RF 100-500L, this one is much lighter and compact. I wish that it comes with a lens hood. The Canon brand lens hood is quite expensive. Other brands are much cheaper and serve the same purpose.

    For the price you cant beat this lens. My only gripe is the low light performance is not great but at this price point im very happy with its performance overall.

    I bought this lens to get photos of birds and other animals from far away. It's perfect. It's basically an upgraded version of the 100-300 from the older DSLR cameras. Feels great and not too heavy.

    This lens was my first "expensive" upgrade for my R8 - have enjoyed using the lens. I've noticed the bokeh effect on this lens is really unique and different from lens I've used before. Perfect for sports photography or capturing event photography from afar

    Bought this for my R6 and put simply it is the best value telephoto lens for the RF mount. It uses the full range of autofocus points and has very fast focus.
