Canon will officially announced the RF 200-800mm f/6.3-9 IS on November 2, 2023. This lens seems to be generating a lot of positive hype. There are still some unknowns about the lens, but we only have to wait a few more days for the launch.
The Camera Insider is reporting that it’s definitely not an “L” lens and won’t have “L” lens level of weather sealing, which shouldn’t come as much of a surprise. Only the 400mm f/4 DO IS lenses had sealing without the “L” moniker, but I think it’s ok to lump those DO lenses into the “L” lens category.
We have been told that a past patent from over a year ago is pretty much what to expect from a technical standpoint. The patent shows f/8.5, but will be sold as an f/9. This is pretty normal for patents and released products.

We have also been told that the RF 200-800mm f/6.3-9 will be compatible with Canon’s RF teleconverters, which will quite welcomed for certain shooting situations.
As for the focus motor, we see a lot of “STM” in reports, but we have not been able to confirm whether or not this lens will be STM, USM or a new type of focus motor. The RF 10-20mm f/4L IS STM was a surprise with the STM motor, but the focus groups don’t really have to move all that much for such a wide lens. Something like a 200-800mm will be different in that regard.
There are some Canon shooters that were hoping for supertelephoto lenses like the Nikon 600mm f/6.3 VR S for the RF mount. While that isn’t happening this coming week, stay tuned for some information on those sorts of lenses in the near future.
