My preordered RF 24-240mm F4-6.3 IS USM arrived today. It did not work at all on my EOS RP until I updated the camera firmware. Once updated, it worked nicely. I find the size, weight, and balance to be a good fit for the EOS RP. Zoom action is smooth and requires similar effort throughout the range. No lens creep with the camera pointed up with the lens extended or pointed down and retracted. Focusing was fast and accurate in both one shot and servo. I will mainly use this combo for travel and static/slow subjects, but I did test for birds in flight. I had no problem picking up and tracking gulls and waterfowl against the sky with almost all photos in focus. My impression was that servo tracking was much better with this lens than when I tried the RP with similar subjects and adapted EF lenses. It will take some time for me to have an opinion on image quality, but the zoom range is impressive (example attached).
