Canon’s new RF 600mm f/11 IS STM and RF 800mm f/11 IS STM lenses are quite unique, and they offer an affordable chance for photographers to check out extreme focal lengths. If you are interested in them, check out this excellent review. 

Coming to you from Tony and Chelsea Northrup, this great video review takes a look at the new Canon RF 600mm f/11 IS STM and RF 800mm f/11 IS STM lenses. The Northrups test them out on both the powerful new Canon EOS R5 along with the budget Canon EOS RP. The RF 600mm f/11 and 800mm f/11 both caused a bit of confusion when they were first announced due to their highly unusual maximum aperture, but with modern optical designs and the powerful autofocus of Canon’s new bodies, they look like they could be a very intriguing option for a wide variety of shooters who would like to work with extreme focal lengths but do not want to drop tens of thousands of dollars on top-shelf supertelephoto prime lenses. And given their performance, it looks like the company has a couple of potential winners on their hands. Check out the video above for the full rundown.
