This will definitely be on my list for future lenses. Positive for me:
  • Focal length range (obviously)
  • nano USM
  • Weather resistance, and not just a couple of gaskets
  • only 2 kg (for a 800 mm lens)
  • Much shorter close focus distance than the f/11 lenses, comparable to the 100-500 mm
  • Support of extenders over the full zoom range (according to Canon), although I would not have use cases for more than 800 mm very often
  • relatively good resolution
These are the MTF charts of this lens compared to the 100-500 mm and the 800 mm f/11

At 800mm, it's darn closer in the centre to the EF 400mm DO II with a 2xTC.

I'm sorry AlanF, but you are required to buy this lens. I will be making a purchase decision based on your CanonRumors review of it for bird photography.
I have ordered one (I'll send you my bank details for reimbursement). It's not ideal for my style of photography - I prefer very light lenses for general hiking and also small for travel as I can put everything in hand and carry on luggage, and the magnification at mfd of 0.8m at 200mm is only 0.25 and even less at 0.2 at 800mm where the mfd is 3.3m, which limits my dragonfly shots. For BIF, I don't like going above 500mm on FF. But, if it's really good at 800mm I'll have plenty of use for it. (It looks as good and is lighter than my old 400mm DO II at 800mm).

Hi Alan!
Where did you get that data from?
Canon Germany didn't offer anything but the 200mm data.
Thanks for sharing.

As a wildlife/landscape photographer, I'm wondering if the 200-800 fills a need. Along with my R5 and 5D4, my "reach" lenses include the:
  • RF 200-500
  • RF 800 f/11
  • EF 70-200 II
  • EF 100-400
  • 1.4x (both mounts)
Note: I really don't use the 100-400 and the 70-200 much. I borrowed the 800 a few weeks ago and really enjoyed it (except for MFD), especially with the 1.4x, something my 100-500 doesn't play well with.

Do I need the 200-800, or is there already too much overlap? Maybe skip the 200-800 and buy the less expensive 800mm f/11 -- OR -- sell everything except the 1.4x and buy the 200-800.

I have the 800 f/11 that I often use with the R7 and 1.4x for hummingbirds. I ordered the 200-800 because it focuses substantially closer and the zoom will be liberating. The MTF curves posted above also suggest it will be sharper at 800 and Canon says it is very good with extenders. On the R7 with 1.4x, you are looking at a FL range from 450mm to 1800mm equivalent. Think about that.

Looks like it will be somewhat better than the 100-500 with 1.4x at 800 and that makes sense with the 95mm objective.

I can't really tell from your list what you actually own or just want. The 200-500 is still vaporware. Since it will command a $17k price tag, isn't buying a 200-800 pocket change? With the RF 200-800 now being offered, I would not buy the 800mm f11. Its on your own it, want it list? But below you borrowed it?

I'd sell my 5D4 and any EF gear (you are not using regularly) ASAP. It took me a year to sell my 6D2 and a few L lenses. Granted I held out (private sale) mostly because I wasn't going to take pennies from KEH, and the gear was LN- or A+. This will give you plenty of capital to put towards the RF 200-800.

Then when the R5 mkII arrives, sell what's left (or what you don't use) and go all in on the 200-500. you may decide the 100-500 and 200-800 + TC does a good enough job. Depends on if you are OK being without 2 body's. I have one, went to Alaska this year and realize the value of a dedicated super zoom body now. Lens changes were murder. Not sure what its going to be yet. Might be a plain vanilla R5 which will be cheap once the mkII is released. Some stuff for you to consider. :)
