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.
More to come…
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).
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.
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.
So maybe an RF 14-35/2.8L could have a 77 mm filter thread?
I second this! Or even a compact f4 version with IS. And 14-30 like Nikon's is plenty at that end...
Emphasis on the ... EF ;)
Oh my.
Oh my.
Oh my.
Maybe I've missed something, but so far we haven't seen anything wider than 16mm and an aperture of at least f/2.8 with an actual filter thread. If I saw it right, all three RF wide-angle lens design patents showed a bulbous front element. Also, maybe the zoom range has be narrower, like 14-28mm f/2.8 or 15-30mm f/2.8, that sounds much more realistic.
Or it has to be reduced to f/4 like with the Nikon.
