Canon DSLR Rumors

Canon will do a Livestream for the EOS R5 and EOS R6 official announcement [CR2]

I have been told that Canon will be doing simultaneous live streams in the USA and Europe for the announcement of the Canon EOS R5 and Canon EOS R6 on July 9, 2020, if true, I suspect we’ll be seeing a teaser for the event very soon.

The same source claims that the RF teleconverters will work with any RF lens (I’m not sure about this claim). I’m also not sure if things will work differently with adapted EF lenses.

I have also been told that there will be more “cool” adapters and lens add-ons coming later this year. I wasn’t told any more than that.

I am not seeing how that would be possible given the protrusions on the teleconverters and the position of the rear element on many current RF lenses.

It would be interesting to know if RF 1.4 + RF-EF + EF telephoto would work.

When I switch from my current crop sensor I will probably want a 1.4 or maybe 2.0 converter to go with my 100-400. I was planning on buying an EF converter, but if an RF converter would work the same with the only difference what end of the teleconverter the RF to EF conversion happens, that would make the RF teleconverter a much more appealing purchase since it would work with both RF and EF lenses.

What you've already seen that were presented (not really) as the new teleconverters in photos(with almost zero details) might not be what really is. Canon says, "Psych!" on announcement day.

I still think we were seeing mockups that put an RF shell over the old EF TCs. Betting the RF TCs are flush with the ends.

There’s really no other way around it if it’s going to work with any of the current f/1.2 primes that have the rear elements so far back, unless maybe in firmware they limit the close focusing distances (Ex: RF 50 f/1.2 + RF 2x TC becomes RF 100 but with a minimum focusing distance of 2m).

If the TCs have a collapsible section holding the elements, Canon would need to use the IBIS mechanism to move the sensor rearward — not sure there’s enough room in the camera body to accommodate this. Or they could collapse in sections to keep it all flush on both ends.

Given how creative Canon is with lens design, anything is possible. But flat TCs would be the simplest explanation.

Yeah, I wouldn't see the point of collapsible sections when the thing could be built flat to begin with. I think "collapsible" is people grabbing at straws that aren't there.

Regarding the “cool” adapters coming, this has got to be 1.4x and 2x flip-switch TCs for EF big whites. Then all eventual RF big whites would have a removable rear segment to reveal an EF mount so they could be used on a DSLR (at the slower EF mount communication protocol) or accept the flip TCs that engage the extra RF connections.

RF Big Whites:
All intact — RF mount
Rear segment removed — becomes EF mount
Rear segment removed — accepts flip-TCs

This way there would additional functionally added to EF big whites, making those that use them want to switch to R bodies. And Canon could wait to make RF big whites until the next planned upgrade cycle for each lens since the urgency to deliver big white RFs would be removed.

Excellent, both about the live stream and the potential for the TC's to be compatible with the RF glass!

I only hope the live stream has better streaming than the last one, it kept cutting out and freezing even with a full fibre connection
