Canon announces $17K 800mm F5.6, $20K 1200mm F8 lenses for RF mount
3140 g (6.92 lb) vs 4.5kg (9.9lbs) of the EF 800mm

3340g (7.36lb) vs 4.5kg (9.9lbs) of the EF 800mm

My guess was right! It's $17,000 or more! lol

Correct me if I'm wrong. In the write-up on DP Review, there is this sentence about the 1200 f/8 lens: "It too supports Canon’s RF 1.4x and RF 2x extenders, which turn it into a 1680mm F16 and 2400mm F32 lens, respectively." Shouldn't that be 1680 f/11 and 2400 f/16??Canon announces $17K 800mm F5.6, $20K 1200mm F8 lenses for RF mount

Many thanks Alan. I had forgotten your extensive tests on almost every combination.I found in the final testing of my second copy of the 400mm DO II that at f/8 with the 2xTC III it was very similar to the RF 800mm f/11 and did improve slightly on stopping down to f/11. My first copy of the lens with the 2xTCIII was also similar, but I don't recall it improving when stopping down. Anyway, my copy of the RF 100-500mm + RF 2x beats both.![]()
Its been nearly a decade since I thought about it but I think 1.4x should means 1-stop of light loss and 2.0x would be 2-stop of light lost.Correct me if I'm wrong.

Surfing is one area I always forget where you want/need these huge lenses and I very much doubt it is in the extreme low light that wildlife shooters desire.My main camera shop guy asked if I was interested in either of them since I had already brought the 400 2,8 Nikon and put down a deposit for the Nikon 800mm. I placed an order with him for both since they will moistly be used on my RED Raptor for surfing footage. Expensive year already but I swallow a lot of this through my accountant so no biggie really. Not expecting much change from 35k euro and that's with my generous discount...
Yes, I love using super teles along with say a 100 - 400 and some wide angles. I have various bodies and a couple are used solely on super teles, 1 Nikon, 1 Canon and depending on where I am in the world I can set them up and everything else is done remotely. I do some low light/dusk shooting but normally thats always with a 400 2.8 or lower focal length.Surfing is one area I always forget where you want/need these huge lenses and I very much doubt it is in the extreme low light that wildlife shooters desire.
I can only say, as a physicist, that the fundamental principles should be the same in such Canon and Nikon lenses. The design details surely differ, and one reason I guess is that Nikon had to work around earlier Canon patents.Canon's DO II technology differed from the first by having a double-gapless Fresnel zone plate instead of a single. I have searched for whether Nikon used the newer Canon technology in their PF lenses and have found no evidence for it. So, if anyone could enlighten me, I'd appreciate it.
The problem in my opinion is that your right and left eye won't be able to peer at the same time through two cameras to catch sudden action, if you don't have a very special physiognomyYou must have been with a fella with a 800/5.6 VR and 600/4.0 VR then.
I know of a handful who completed their sets of fast long primes that would bring half their fleet with them to maximize their photo keeper rate.
