Canon has been releasing some mightily impressive lenses the last few years, but two of the more unique options we have seen are the RF 600mm f/11 IS STM and RF 800mm f/11 IS STM. They are quite affordable, however, offering photographers the chance to use extreme focal lengths without breaking the bank. How do they hold up in practice? This great video review takes a look at both of the lenses and the images they produce.
Coming to you from Jan Wegener, this excellent video review takes a look at the Canon RF 600mm f/11 IS STM and RF 800mm f/11 IS STM lenses. Certainly, with a fixed aperture of f/11, these lenses are rather unusual, but they show quite decent image quality and performance. In particular, I am impressed by their background blur. No doubt, an f/5.6 or f/8 lens will give you better blur, but you might be surprised by how well even an f/11 lens can isolate your subject. Beyond that, with the impressive ISO performance of Canon's new bodies, like the EOS R5, you can afford a narrower aperture in a wider variety of situations. Check out the video above for Wegener's full thoughts on the lenses.
Those AF limitations are "unusual". Limiting the focus points to a small area of the finder might be problematic. I wonder if this was done purposely or is this a natural design outcome.
Worth buying??....Not for serious photographers..
