We have been told that SIGMA is actively working on an RF mount lens roadmap and will announce their plans sometime in early 2020, I would suspect an announcement ahead of CP+ in February would be the ideal time to do so.
Apparently distributors have received some early information about SIGMA’s plans, but our source on this one didn’t want to divulge any more information.
It would be great for the EOS R system if SIGMA gets on board early with compelling lenses.

I'm hoping for Sigma to release their excellent and affordable 2,8/14-24 WA zoom, unless Canon produces one of those "crazy" UWA primes...

EOS-R, RF and EF Lenses of all types.
I am very happy with the Sigma 45mm f2.8 DG DN on the Leica SL.
I especially appreciate (1) aperture ring with "A" position; (2) great image quality; (3) great build quality ... but $550 seems high for a slow normal prime.

Eagerly waiting for Macro lenses for Rf mount(150/180mm) along with Aps-C sized sensor camera. Hoping Sigma answers the lack of macro(1x) options for RF mounts.

I want to see an RF Tamron 35, sigma 35, and Canon L 35 go head to head. I almost bought the Tamron 35mm 1.4 but don't want to invest in more EF glass.

We’re all assuming, I assume, that these will be new designs, rather than remounted current designs?

Why not just use the current Canon mount with an adapter?

Has anybody been using current Sigma lenses with the R? I have a macro, but I just realized I haven't tried it yet!
I'm using the Sigma 35/1.4 on my new RP with firmware 1.4. The autofocus is reasonably accurate and reasonably fast, but isn't as good in either respect as Canon's 85/1.8 on the same body. Would an RF native Sigma lens perform better than a Canon lens? I'm not sure.

EDIT: "as well as," not "better than" (a Canon lens).

I’ve used my f1.8 zooms on the R with crop, works seamlessly for video. Af at 60fps didn’t work but maybe the firmware fixed that. For photo it does lower your megapixels though
