Third party lenses for Canon RF mount?

How long will it take before the big Japanese third party lens manufaturers (Sigma, Tamron, Tokina) begin releasing lenses for the RF mount?

I've been happy with my Sigma EF-S lenses and would appreciate to see less expensive RF lenses available.

And can we expect them to work with functionality similar to Canon's own RF lenses?

Has licensing the RF mount protocol been on the table (officialy or unofficialy).

I understand that the RF mount is electronically and digitally more advanced, but it appears that on sensor DPAF should mitigate the problems with front- or back focusing seen on DSLRs?

The few third party lenses released in RF mount until now are rumoured to be EF-lenses electronically even if they optically are designed for a shorter flange distance. I know next to nothing about this, but would love to hear from someone more in the know.

Re: Third party lenses for Canon RF mount?

It's be very happy to see the third party lens makers make RF mount lenses. As for licensing the RF protocol, not going to happen. Canon doesn't license their protocols. Third party lens makers have to reverse engineer it.

Now that the Samyang 14mm AF for the RF mount is available at multiple outlets it won't be long until the first reviews will turn up in the usual places. Waiting to see/read how it performs on the R/RP!

Re: Third party lenses for Canon RF mount?

Yes, good news indeed. Wonder if they'll allow the fast refresh EVF?

It all depends on how complex it is and whether or not the RF protocol is encrypted. I'm not convinced that the Samyang AF lenses aren't just using the EF protocol (R series cameras support EF protocol natively, so their adapter doesn't do protocol conversion and that allows lenses to fool the camera into thinking the EF lens with an adapter is attached).

If RF protocol is not encrypted, it shouldn't be too long (perhaps a year or two) before we see third party RF lenses.

For the Samyang AF 14mm 2.8 RF, I can report that on a Canon R (FW 1.6.0.)

  • the lens registers as "Samyang RF 14mm F2.8"
  • Correction data is provided for Peripheral Illumination Correction, Distortion Correction, and DLO which all can be enabled (and indeed improve jpg data)
  • EVF high speed refresh is disabled for the lens
  • autofocus works fast and reliably (including eye AF)

It seems that they got the firmware sorted out well enough. And I think that if Samyang would release their pancakes with a RF mount they might sell quite well.

What? Sacrilege!

You don't want the 28-70 f2 or 50 f1.2?

Seriously though, in the old days we used to choose systems often on the basis of the lenses available. If you are not buying into the new EOS R for the Canon lenses, why are you buying into it? Wouldn't you do better to buy Sony E mount where there are zillions of Sigmas and so on available? Sony have the most advanced mirrorless right now.

I’m in this for the results, not the bragging value. Edit: I’m all for bragging about my results, but not about the brand on my gear.

High ISO is fine and I’m not a big fan of very shallow DOF. And the price is outrageous, IMHO.

Contradicting yourself with this brand nastiness was not your finest hour.

So you are a brand fanatic... why would you want third party lenses then?

This thread you made is filling with self-contradictions.

I’m really sorry you see it that way. First, I can’t see where the “brand nastiness” comes in. If I don’t like shooting with Sony, why should I? Not to satisfy you, I hope.

Second: I don’t brag about using Canon, it’s just the brand I chose. When I did, Sony was still experimenting with SLTs, and look where that ended. If “sacrilege” is your reaction, you may be the one who’s passionate about using one brand only. Feel free, but don’t expect it of me.

Third: I am not a wealthy man, I must prioritise. I can’t afford to buy the f/2.8 trinity, but I’d like a decent UWA zoom of lesser aperture.
