In terms of which of these might actually become products in the near(ish) future I'll say:


Canon RF 50mm f/1.8 - Obviously yes
Canon RF 80mm f/1.4 - Nope
Canon RF 85mm f/1.4 - Nope
Canon RF 85mm f/1.8 - More Nope
Canon RF 100mm f/2 - I'm going to say no
Canon RF 135mm f/2 - Maybe
Canon RF 300mm f/2.8 - Yes

I know some people want a 135mm f/1.8 or 1.4 but the EF 135 2.0 has always been a spectacular lens, and part of this is due to the relatively small size and low weight. Not sure I'd want a more expensive and heavier version.
How can you say Nope to an 85mm 1.4 or 1.8 (for canon the 1.2 will never be a hot of the shelves lens) they need smaller lighter version that cost half the price. You might not need it but the lineup does.

I'd be very happy if they released an RF 135 f/2L IS. Nano-USM and weather sealing are more important to me than 0.5x macro, but I certainly wouldn't mind it if they could include all three, as long as the IQ meets or exceeds that of the EF version, and the price and weight don't get completely out of hand.

Canon RF 300mm f/2.8 , could this be the first of the big one whites for wildlife? Want to see the 400mm F2.8 and 500mm F4
Since they never updated the EF to vIII, I would say this is guaranteed next year before the Olympics and released with the EOS 1R. The longer great whites, I think we might be waiting a bit since the EF vIII's are still pretty new and work perfectly with the RF adaptor.

I want my RF 200-500 f4-f5.6 + integrated 1.4x TC @f6.3 & under 6lbs or less!!!!! I agree that this may be the first BW. I actually expected both the 300 & 500 since they did not get EF Mark III updates and weight reduction.

The 80 and 85mm f~1.4 don’t make much sense after the near perfect RF 85mm f~1.2
I disagree. Ive the EF 85mm f1.4L IS USM which I use often. I bought it because unlike the 1.2 it has IS and whilst the bokeh is different it’s still very creamy when I use it for portraits.

If the 135mm f/2 is the fastest at this focal length I will be disappointed. Really want at least a 135mm f/1.8 or 70-135mm f/2.

Canon is the maker of 03 85mm between 1.2 and 1.8...

Good to see the 300 f/2.8 patent, but where the hell is the 500 f/4. Hopefully Canmon will switch to linear drive motors too for the superteles and consider a 600 f/5.6L DO IS or 800 f/8L DO IS.

Other than that the 85 f/1.8 and 135 f/2 are welcome.

Where are the UWA fast primes or fast zoom? Canon has ceded this market to Sigma and there are a lot of us that would shell out money for a native option. They have also been behind both Nikon and Sony in this space. Come on Canon, show us astrophotographers some love and what the RF Mount can do!

If the price is half of the 1.2 than it will be, not all people can afford $2000+ lenses, and if Canon wants to increase their market, lenses is where the big deal is. For once you buy a body, you will probably use it until it dies out, those cameras, even 10 year old gives wonderful images. but you will always like to expand your choice in lenses.The same goes to the 600 and 800 F11 lenses, those are a good compromise between cash and focal length, many people who like to shoot animals will buy them cause now they can afford them instead of $3000+ white lenses.

I have enjoyed borrowing the EF 200-400 f/4L + 1.4x, but I have a hard time believing that it will be physically possible for them to add an additional 100mm of reach while simultaneously reducing the weight from 7.9 lbs to under 6 lbs. Much more realistic to consider the development from the EF 100-400L II to the RF 100-500L, which dropped a half a pound while adding a few mm in overall length.

Spot on for me at least. I will buy either the 600mm or 800mm before I upgrade my camera (even though I'm jealous of AF II). Also, if canon comes out with any one of a native RF f/1.4L prime in 35mm, 50mm, or 85mm for ~$1600, I will buy it immediately. I expect to wait a while though given the nice alternatives already available to be adapted from EF.

The EF 14mm 2.8 II dates to 2007 and is seemingly due for an upgrade.
With the RF 15-35mm going down to 15mm at f/2.8, I don't see much of a reason for a 14mm f/2.8 prime, which is also very expensive. If Canon decides to produce a 14mm prime, I'm guessing it'd havea larger max aperture (f/2?) to better differentiate it from the zooms (RF 15-35, EF 11-24).
