Canon Says it’s up to Sigma to Make Full-Frame RF Lenses

Thanks for the clarification - this helps a lot. I've noticed that the lens corrections appeared to be working despite what I thought the menu was saying. I know that the Sigma Contemporary lenses lean heavily on digital corrections, and the embedded jpegs don't show noticible distortion. It makes sense that the distortion correction is forced on, because it's an integral part of the design of these lenses.

You bet! Happy to hear you're experiencing the same. I'm over the moon with Sigma lenses on Canon bodies and I am excited for the R7 Mark II because of it. Should be a stunner with the 17-40mm f/1.8 which I adore.

Canon wants 30% of the sale price as a fee for anyone using the RF mount. Pay or get sued.

It does seem like there's something like this going on -- but have you found evidence for it being 30%? I think we're all curious what the backroom deals really are, but I haven't seen any proof yet.

Someone on YouTube said it. I mean, that's proof, right?

I'm a bit jealous. I was so excited when the 18-50 f2.8 was announced that I pre-ordered it. I rarely do that, preferring to see what the critics say first. But I had confidence in Sigma, having had several of their DSLR APS-C lenses in the past. But ... I had no inkling that a 17-40mm f1.8 was in the pipeline! I'll spring for one eventually I'm sure. But the R7ii is the first priority.
