Yes...I think they more look like a 600/4 with a 1.4 or a 2.0...more so than a 400 with 2.0 if you compare the designs. The 1200 for sure looks like a 600/4 with just extra length of ~ a 2xTC on the end.

And I guess the silver end (which is essentially an EF-RF adapter spacer) is here to stay as a signature design cue for the RF superteles.


That's an odd decision. They are continuing the "silver tradition" only because it was done for a couple of "converted" lenses in the past. I'm also not sure why they did it in the first place. Of course it doesn't matter if the new lenses are optically flawless and carry modern AF motors. Likely, LensCoat and RolanPro already got everything covered (pun intended ).

High return?
The original 1200 cost something like $85K. They now go for close to $200K I think??
Probably the ONLY lens ever made that actually gave a return. The only investment lens Canon ever made!

By high return I meant ROI for Canon, not the consumer. However on your point, another example of a Canon lens that appreciated rather than depreciated is the the EF 50mm f/1.0L.

After seeing this release leaked doc and looking at the 600 and 400... looks like it is a re-hashing of the to EF/RF lenses with corrected optics similar to a 2x.

Theese lenses are made for "companies and some very rich people" , the 1200 is priced more then a Tesla model X?
As a hobbyist my max is 15 000 USD for my equipment

No, if you compare them they are different designs at least at the rear end...just look at the different sections.

Canon rumors had this to say about the 1200 optics:

With the weight being so similar, as well as the minimum focus distance being almost identical, one might suspect this was an RF 600mm f/4 dressed up with an attached teleconverter. But that lens has a different optical design, with three aspherical elements and three UD elements. The 1200 is to have two large fluorite elements, one Super UD element, and a single UD glass element. The lens design schematic was not included in the leak, but details in the release show materials used require a different design.

That's why I look at separate TCs as optically and mechanically not that good.

It would be a disaster if they simply added TC glass into the 600/4 optical path. Imagine how bad would be the IQ. It seems like a hybrid design. Some stuff is "borrowed" from the 600/4 and some stuff is new. I'm really curious to see the MTFs.

There has got to be more to the story here. According to the leak, it's a completely new optical design that nearly weighs the same and has close to the same MFD of 4.3m.

Canon isn't clueless when it comes to selling product. If these were actually the 400 and 600 with fixed 2x TC's, I'm pretty sure Canon knows they wouldn't sell any. One would need to be foolish to give up the flexibility of just using the RF 400 or 600 and mount whatever TC they want/need for additional reach. Why would anyone lock themselves in to a fixed monster length with nothing to gain.

Yeah I guess the leak only says the "front group" is the same as the RF 600. Not sure what they define as the "front group".

So certainly more than just a 2xTC slapped onto the 600/4.

I guess the only reason someone might buy these if they actually were just the 2xTC elements tacked on would be the ability to use 1.4 and 2.0 RF extenders in addtion.

But seeing that they are a different design means they have even more value if someone only needs 800 or 1200 as their minimum starting point.

But I think it can be said these aren't a typical design as the MFD has been kept to 600/4 type MFD and the length doesn't look as long as it should be with 1200mm. Typically even 800mm lens MFDs are quite far. The EF 1200/5.6 had a 14 meter MFD

Can't wait to see the price

They are incorrect....the RF 600 has the same single Super UD element and 2 Fluorite elements. Not sure about the single UD glass element but I think that is the front element for both.

My guess is everything ahead of the two black hash lines will be the same....the rear is where they will differ.

I'd bet the 800 will be a front half RF400 clone and then a similar redesign of the rear as whatever they do with the 1200. That should maintain the 400's MFD which is killer for a native 800 without using TCs.





Purple is Fluorite, Green is Super UD

US$14k and US$15k? Deliveries start early 2023

They didn't mention any AF improvements in the press release. That's kind of bothering me. I didn't like the RF 600/4 AF. A pacemaker-stopping magnet would be more welcome

At this point it's starting to look like they are killing the 500 lens. It never received the mark III facelift nor the RF mount.


I have noticed that the EF 500mm has been back-ordered on the BH site for over a month (at least). I was thinking/hoping this was a sign of an eminent announcement for an RF 500mm f/4.

No offence, but man, I hope you are wrong!

Besides it being as "expensive as L" I have no doubts that it would also be one L of an L lens!

The price would tell you if it just has a 2x stuck onto it, for sure. If itís $100K definitely a 1200.
Borrowing the front lens group might just mean borrowing the placement order of the group not literally taking the actual physical group and dropping it into a 1200.
Without looking Iím sure the objective lens in a 1200 is way larger than a 600 this thus mitigating the use of the same exact group but I havenít read any of the material since neither lens is in my future!

600/4 is the same front element size as 1200/8 at 150mm. So this is easy to just use the front half of the 600/4. Ditto for the 800/5.6 compared to the 400/2.8. They will likely share the same front groups and have a 143mm front element.
