Canon registers a new RF mount lens

It looks like Canon may have one more lens to announce in 2021. They have registered a new and unreleased lens, with the product code 5554C005AA.

The latest Canon lenses to be announced the RF 16mm f/2.8 STM has the product code 5051C005 and the RF 100-400mm f/5.6-8 IS USM is the 5050C005.

E MfOApUUAEeRse 728x196 - Canon registers a new RF mount lens

I don’t know for sure which lens is being registered here, but if I had to wager a guess based on the Canon Rumors RF lens roadmap, I’d go with an RF 35mm f/1.2L USM. Again, that’s just a guess!

I would think a 35L would definitely create enough hype to be announced on its own.

More to come…

They need to make a lightweight f1.8 zoom is for s35. It's way overdue. The f1.4 35 is still kinda new and excellent and we got the f1.8. Personally I am not in a rush for that lens over other lenses. I rather a 135mm over that because the current one is ancient.

While I love the idea of a competitor for the Sigma zooms (with out the dragon like focus breathing please) it will never happen as Canon's policy is that FF is the one true format handed down by god never to be blasphemed against lest an army of Sonyboy terrorists be unleashed to wage Jihad against the infidels.

I could see Canon announcing a new lens around the time that the R3 ships, they did announce the RF 50mm F/1.8 and RF 70-200mm F/4L IS on their own in November last year, so maybe that's a trend around the holidays.

I'll be selling my EF 35mm F/1.4L II around that time, too, so that will be interesting to consider. Part of me feels like we should expect the lens to be about the size of the EF + adapter, but I'd love to see them keep it relatively similar in size without the adapter.

What does the text "RF50mm 1.2L USM" (right after the 555...5AA code) mean?
Translation of that line:

Article Brand "Canon", model: 5554C005AA, RF50mm F1.2L USM

It would appear that the model name of the lens being registered is RF50mm F1.2L USM. I don't recall from past rumors based on Russian product registrations had accurate model names, I thought they usually didn't have any at all. If the model name is accurate, it sounds like this may just be new paperwork on an existing lens, but with the number of sources repeating this I would have expected that to have been caught by now if that were a possibility.

You're joking, right?

There's only a couple f/1.8 zooms that I know of, and they have an extremely limited range, are far from lightweight, and don't have IS. Even if we broaden it to just "faster than f/2.8", those are still all very heavy, only four that I can think of off the top of my head that have autofocus (one of which is Canon's own 28-70 f/2), and still none of them have IS. Making suck a lens stabilized is probably possible, but would add to the cost and weight that have these lenses already as niche items, and would introduce compromises to an already complicated optical design.

Please be a RF 500 mm f4 DO lens!!
While I hope for the sake of my birding friends that we're going to continue to see more diffractive designs, I suspect Canon might be dropping the "DO" designation. It's been seen as a negative by segments of the market who didn't "get" it, especially in regards to the 70-300 DO, so I wonder if that's why Canon didn't mark the two f/11 teles as such. Of course, it could just be that they're reserving it for high-end diffractive lenses.

While the advantage of a short flange distance typically doesn't make much of a difference in the size of teles, Canon has already shown a couple ways they intend to do that, so I expect they could do something for a fast prime explicitly designed to be compact.

18-35mm f1.8 sigma would like to have a word with you. Light and compact. The lens of choice for many videographers. Issues... slow focus, questionable build quality, no IS. :cool:

It should be smaller. Look at a Leica 35/1.4 ASPH compared to the current EF 35/1.4 MkII. Maybe 1/2 the length, 2/3 the girth, 1/2 the volume.

Basically, the most natural lens designs start "wanting" to have elements within 40mm of the sensor as you go wider than 45mm or so. So SLRs always must have a retrofocus design. Rangefinders and now mirrorless have no need for that so the lens is both better IQ (except possibly in vignetting) and smaller, lighter, sharper.

At least that's the way it used to work up until 2000 or 2010. The most recent high-end lenses no longer have any relation to the classic double Gaussian design. The EF 50mm, whether 1.0 1.2 1.4 or 1.8, all were very recognizably tweaks of the standard design going back to the 1930s or whatever. But now the sharpest lenses in the world are the Canon 50/1.2, Leica APO-Summicron 50/2, and (?) Otus 50/1.4, and their designs are no longer understandable to the man on the street. So it's possible a 35mm f/1.2 would actually look a lot like the 50/1.2, but the lens formula would have absolutely nothing to do with the EF 35/1.4 MkII.

It isn't exactly light though -- 810g. The EF 24-70/2.8L II is 805g and the RF 24-70/2.8L IS is 900g. The zoom range is also limited: slightly less than 2x wide to tele, while the 24-70s are slightly less than 3x.
