I consider myself a semi-professional photographer and this lens is now a great addition to Canon's RF lens collection. While it doesn't have autofocus, I don't really miss it, and the R-series' peak focusing is very useful. It takes really great pictures - I was impressed with the clarity of the image. The aperture ring is well positioned and the lens is neither too big nor too heavy to be carried around comfortably. The build quality also seems to be very good. You may need to activate the shutter without attaching a lens in the EOS settings as this is not a Canon lens. I highly recommend this lens if you need to shoot at longer focal lengths. longer than the 24-105 that comes with the EOS R.
