I sure hope Tamron just on the bandwagon too. They could really round out the the lens line up. Canon has great top of the line lenses but they are missing the midrange lenses.
I'd love a tamron 28-75 f2.8 like the sony E mount version

The 1.8 sigma art zooms are designed for aps-c so the camera automatically crops the sensor to avoid vignettes, but I believe your macro is designed for full frame sensors so you should be good.Why is that? (As soon as I get a chance I'm trying my macro.)
Because remounted lenses aren’t a big deal. They won’t perform as well, and will be bulkier than otherwise.Why not both?
About 50 % less expensive, and really really good.With Canon's UWA RF zoom going down to 15mm, I wonder how much demand there will be for a 14-24. Smaller zoom ratio, no IS and not filterable with a screw on filter...
I'm not assuming that. These are third party manufacturers. They need design flexibility so that they can interchange mounts among Canon, Nikon and Sony. I imagine they will look at each lens and determine if it requires a new design for mirrorless. I would say it is likely that some of the lenses will be specifically designed for mirrorless bodies, but probably not specific to Canon. They may feel some lenses don't need to be specific to mirrorless -- for example, I wouldn't be surprised if the 600mm zooms are basically remounted current designs, as there is not likely to be a lot of difference in size or weight between a remount and a mirrorless-specific lens at those focal lengths. Since EF mount lenses already perform equally well on R bodies, I would think these would as well regardless of what route they take.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!
Well, for that one lens, yes, but not for the others. they don’t need to specifically be for the Canon. We see a number of lenses designed for Canon, Nikon, Sony, and occasionally another DSLR. Those all have had back focus of about the same amount, so you design for the longest, and the rest fall in line. The same thing here, design for the Sony, and the rest will work as well, with slightly longer mounts.I'm not assuming that. These are third party manufacturers.

Ok. What was wrong with the 85/1.4 Art again?Sigma is going to have to keep their lenses cheap as chips for RF or they won't sell. I honestly prefer the IQ of my RF 24-240mm over my Sigma 85 Art. If Sigma is that far behind in IQ they're not gonna sell anything unless its cheap.

I have the Sigma Art 50, 85 and 135. Had screwed around with the Sigma USB dock when using them on the 6DII, but set everything back to zeroes to use them adapted on the R, and I haven't touched the dock since. They all focus fast and spot on. The 85 Art with the R's updated eye focusing is outstanding.
For the EOS R it'll be interesting to see what Sigma does. I can't imagine the Sigma RF mount would have the function ring like Canon? Personally I'd probably only use a Canon zoom. As for prime lenses I expect any Sigma Art RF will be optically excellent so it will probably come down to a cost, performance, features, show down with the Canon equivalent.
I'm not a pro so I don't need the RF 50 1.2 for $2100, but the rumor here a while back was Canon will not be making an RF 50 1.4, just a 1.8? If Sigma makes a 50 1.4 I'd have to consider it. But if Canon's rumored RF 50 1.8 is anything like the RF 35 1.8 in features, size, IQ and price I'd definitely go with Canon

I guess Sigma just add an internal mount adapter to their existing lenses to make it as RF mount only but not redesign the lensesWe’re all assuming, I assume, that these will be new designs, rather than remounted current designs?
