Canon has already mentioned that a trio of f/2.8L zoom lenses is coming in 2019 for the RF mount. It’s pretty obvious that we should expect some kind of “holy trinity” of lenses such as an RF 16-35mm f/2.8L. RF 24-70mm f/2.8L IS and an RF 70-200mm f/2.8L IS.
We’re being told that the wide angle lens for the RF “holy trinity” will be wider than 16mm. Both an RF 12-35mm f/2.8L and an RF 14-35mm f/2.8L have been developed for testing.

We have seen a patent for an RF 14-21mm f/1.4L, but don’t expect such a lens to surface in 2019. Included in the same patent is an RF 16-35mm f/2.8L and an RF 12-20mm f/2L. So we think it’s possible that a 12-35mm f/2.8L will what wins out.
Nikon will be coming with a 14-30mm f/4 S and we think Canon will definitely want to keep its lenses the most impressing in the full frame mirrorless world. As such, we expect them to a bit faster and a bit more extreme on the wide end...

Well, depending on price, and whether it comes out in an f/4 flavor later on, that could be exciting. I just don't use wide angle enough to buy a $3,000 or more flagship wide zoom.

Yes, for sure. f/4 and can use normal 77mm filters. I would actually take a 16-35mm f/4 on the RF mount because I'm assuming it would be much smaller, but a 12 or 14mm on the ultra-wide end would be intriguing (also assuming the quality is as good or better than what we have now).

It certainly will be easier for Canon to develop a higher quality wide angle zoom due to the shorter distance bayonet to lens , no need for retrofocus design. This has often been demonstrated by Leica with their superb M rangefinder lenses.
So, I expect some very exciting new wide angle lenses (zooms or primes). This being in my opinion the main advantage of mirrorless, no gains with tele lenses.

I really hope it's a sensible wide angle lens. The 28-70mm F2 is very fancy and all that but impractical (based on size, weight and cost) when compared to a standard 24-70mm F2.8. I'd have much preferred that at launch.

As awesome as these lenses sound, I think it's pretty safe to assume that they'll wind up being roughly the same size and weight as the 28-70 f/2 RF, (or bigger!) so...

OK who am I kidding, if it's ultra-sharp even in the corners, I'd totally buy an f/2 or f/1.4 ultra-wide zoom, no matter how big and heavy it is. I might not take it on every wilderness backpacking trip, but it'd still be an epic lens whenever it's possible to bring it.

If it can match or beat the legendary Nikon 14-24 for astro landscape photography I'll buy one instantly. The coma on the current 16-35 has been less than impressive.

I suspect coma won't be the highest priority for this set in the eyes of Canon. F/2.8 isn't the fastest aperture for astro. The priority is likely to be general use and sharpness. The f/1.4 and f/2 development projects would likely have coma as a higher relative priority. Man, that 1.4 makes me giddy with anticipation. Except it's Canon, so it'll be 3 years of anticipation.

The original 16-35/2.8L takes 77 mm filters, and one of the characteristics Canon has talked about for wide/normal RF lenses is smaller front elements and larger rear elements. This is because they are not so strongly retrofocal so they don't need such extreme negative elements in the front group which are large and inclined to be bulbous in a DSLR lens.

So maybe an RF 14-35/2.8L could have a 77 mm filter thread?

I was hoping to get an EF11-24 but an RF wider than 16: I'd consider it and an RF body and step into the next generation instead on digger deeper in the old generation.
Now if they'd only make an RF body with proper in-body GPS at around the 5DIV (or better) level to match.

This brings up a question: in the days of film the Leica M lenses could be excellent and small due to non-retrofocus (non reverse telephoto) designs. But I think when they went to the M digital there was a problem with angle of incidence with the M lenses interacting with the microlenses, that had to be corrected out in firmware. Wonder if Canikon will need this kind of fix.

I can’t really complain about the current 16-35mm f/4 EF lens; plus with the adapters, we get drop in filters. So, not excited by an R version.
+1 Especially since there are also the excellent EF16-35 f/2.8L III and EF11-24 f/4L.
Emphasis on the ... EF ;)

Canon's going to entice people me, content with our 5D Mk IV and lenses, using new, fast, sharp wide-angle R lenses. That's exactly what's going to happen here.
