Patent: Canon RF 35mm f/1.2L USM

I have been reporting for a long while that an RF 35mm f/1.2L USM was coming for the RF mount. Here we have a very detailed patent showing four different optical formulas for such a lens.

The RF 35mm f/1.2L USM is on the known RF lens roadmap, so I think we may see this lens sometime in 2021.

I'm excited for this lens despite now having no plans to buy it. I'm covered for glass unless the work I do changes.

What I really can't wait to see is a comparison between this lens (should Canon release it) and Sigma's $1500 version, since that's the only autofocus lens on the market that can compete with it, despite Sigma not offering it in an RF mount, yet.

Nah, that's the f/1.0 trilogy coming in 2028. Save your pennies ;)

Indeed. Or maybe "The Ones" when that group comes out.

I thought about "The Clean Dozens" as a play on 1.2 and "The Dirty Dozen" but...sigh...it's a bit of a reach.

We'll, isn't the Sigma f/1.4? Canon's EF 35mm f/1.4L II was a fantastic lens I owned. Sony just released a 50mm f/1.2. Canon setting a new standard, I guess. ;)

It's an interesting conundrum, I'm tempted by this lens, but I actually love the RF 35mm f1.8 so much as a travel/macro/lightweight lens that I haven't used my 35mm f/1.4L II in over a year and will probably sell it to put towards an R3. I'm not sure if I see a future where I have both the F/1.2 and the F/1.8, but perhaps Canon will find a way to change my mind.

Probably safe to assume this will probably end up around $2000-2200, like the RF 50 did.

Nah, there's an f/1.2, now, and it's not even enormously expensive (lower MSRP than the f/1.4 L II, in fact). It was released to almost no fanfare, which makes me wonder how much even photography enthusiasts care about the difference between f/1.4 and f/1.2 for a wide angle prime :unsure:

We'll, I care... just because. ;)

Same. It's absolutely a luxury lens more than something I personally need.

If I had been able to shoot weddings in 2020, I would have enjoyed having it because the bokeh is much smoother than Sigma's 35/1.4, which often makes harsh patterns of grass/trees in outdoor portraits, wide-open.
