Does The Canon RF 200-800mm f/6.3-9 IS USM Have A Design Weakness?

Do you have a backpack in which that beast of lens fits? I guess Lowe's Lens Trekker III would swallow it... or do you use it only in a car or tear it behind you on a trolley?

My 800 lives on a tripod. I got it for the hummingbirds, but now that I have the RF 200-800 that works so well hand held (and focuses considerably closer), the EF800 is relegated mostly to astro.

I would love to see astro shots taken with that!

Here is one of Jupiter on a close flyby last year. EF 800 with EF 1.4x III and R7. Single shot with selective brightening to bring the moons into view.

I wonder what Aaron at LensRentals has seen, and if he’ll do a teardown at some point.

Obvious design flaw... Canon loves thin plastic lately.
Non L is not excuse, they charge pretty pennies for it.

What news do you have on this topic 9 month later? Apparently there was no.
