Canon will announce the following lenses in April:

Canon RF 100mm f/2.8L IS USM Macro
Canon RF 400mm f/2.8L IS USM
Canon RF 600mm f/4L IS USM

Announcement dates can move around, but these are definitely the next 3 RF lenses that will be announced.

Painful that the RF 300mm F/2.8 IS L is not on that list. Maybe Canon is hoping that some will succumb to getting the RF 400mm f/2.8 IS L first. But its the difference between handholding - or not - for me, so not an option. I guess the same goes for many others. Optics of the 400mm will probably tell us a lot of what we can expect of a 300mm.

I remember seeing a patent here for the RF 100mm that had a size bigger than the EF 100L + adapter combined. I'd lose all interest if so. I've been impressed by the compact yet optimally amazing lenses both Sony and Sigma have released recently - would love to see Canon do something similar for a range of f/1.4 primes.

Maybe they are just RF-mount conversions of the version III 400mm and 600mm lenses so they work natively with the RF-mount cameras and teleconverters, while the rest will be new.

Wow! Now I have to decide between the 400 mm f2.8 and the 600 mm f4 lenses. Previously I owned the EF 400 mm f2.8 because in one lens I could get a 400 mm f2.8, which is great for BIF and a 800 mm f5.6. It can also fit in carry on luggage. A 600 mm f4 has the advantage of being a 1200 mm f8, but is not compatible with carry on luggage.

Decisions Decisions....

Lastly, my guesses are prices are $13K for the 400 mm f2.8 and $14K for the 600 mm f4. Basically, a $1K price increase for each. Of course, Canon might keep the prices the same to better compete with Sony. Time will tell...

If the IS works together with the IBIS it would be worth replacing my EF 100L. That’s assuming it isn’t 2x the price!
Yeah it will work, this is my next investment and them the RF 15-35mm 2.8L and complete my combo for wedding photography

It'll be interesting to see the price & weight for these lenses.

I'd like to say exactly what long teles I think they should have, but I've been so surprised at how happy I am with the (unexpected) RF 100-500L and even the IQ of the inexpensive RF 800 f11, that I'm just going to sit back and see what magic Canon has up their sleeves in the future! :)
By the way, if you're interested in how those 2 lenses (with or without the RF 1.4x TC) stack up against each other, I created a resolution test thread (with AlanF's assistance) for them at: https://www.canonrumors.com/forum/t...out-rf-1-4x-tc-for-super-telephoto-use.40240/

Is the macro 1:1 or the weird 1:1.4?
That weird macro is the 1,4:1, meaning not 1x mag. but 1,4x mag - so even better.
It was typed the wrong way but when you read through the CanonNews article, you'll find this:
CanonNews said:
This patent application shows that instead of resolving down to 1:1 like most macro lenses, these lenses shown go down to 1.4x.
This is what the table in the patent shows, too.
