Or the C70 with builtin ND filters….possibly.
but between IBIS and the fact that they still have to support legacy RF cameras with shutters, it's simply not happening with the RF mount.

The Leica M 35/1.4 before the 35/1.4 ASPH was super short too: I recall it stuck out of the body only about 30mm. I had the ASPH though. (It worked fine on the R but I sold it to buy the R5! My photo hobby has to sort of self-cannibalize.)And that patent example is of a lens that's ~40mm (1.5") long, i.e. much smaller than the RF 35/1.8.
Those who worry and speculate about mm or inch don’t even know how to take a photo> Back Focus: 0.29mm
It's technically possible, I suppose, but quite unlikely that it'd be that close to the sensor. That's less than 1/64 inch, for our addlebrained American brethren.
Finally, but I think it’s clear from the patent specs why this lens has taken so long to arrive.One word: finally
Not at all. This lens will be a super seller.Finally, but I think it’s clear from the patent specs why this lens has taken so long to arrive.
Sure, the f1.2 aperture makes a nice statement. However! This lens is substantially larger / longer than the current (and rather excellent) EF 35mm f1.4iiL. Even with the EF to Rf adapter, the EF version is shorter. 155mm long is very large for a 35mm prime.
I thought mirrorless mounts would make shorter wide angle lenses!
I’m guessing that Canon management have sent this optical formula back to engineering several times to bring some kind of benefit over the existing EF version…only to find that at f1.2, this lens becomes very portly and there’s no way around this simple fact. To build the best AF 35mm lens also means building the biggest 35mm lens! Even if this new lens proves to be optically stellar, it’s going to be a tough sell against the current EF version.
The patent for the EF35L f/1.4 II for 2015 shows 129.16mm as the total length, if the elements protrude the same amount, it is only (155 - 129 lens length) - (44 - 20 flange distance) = 2mm longer than its EF predecessor.Finally, but I think it’s clear from the patent specs why this lens has taken so long to arrive.

Yes I was eluding to the suprising retro focus design on a dedicated RF mount lens. I'm pretty certain if Canon could make this new lens smaller they would.The patent for the EF35L f/1.4 II for 2015 shows 129.16mm as the total length, if the elements protrude the same amount, it is only (155 - 129 lens length) - (44 - 20 flange distance) = 2mm longer than its EF predecessor.
That is still surprising to me, since 35mm is less than the 20mm flange distance, so it wouldn't need to be retrofocus anymore. Maybe Canon designed it with fragile photographer egos in mind, bigger is better, no?
Or they let Sigma design it![]()
It's more likely they understood optical physics before they graduated from university and simply were directed to in what order to produce which lenses based on what their research suggests will be most profitable first.Finally, but I think it’s clear from the patent specs why this lens has taken so long to arrive.

It is shorter than the 100-300 - at least ;-)Wait...
What?? A brick?
- Lens total length: 154.96mm
I had a wonderful 1963 Leica M 35mm f2 lens. My favourite lens in the Kodachrome years.It's often true. On social media I see people posting "look at this great lens I found at the flea market" and you look at their photos and it's too soft even on a phone.
Why do you complain?Wait...

Probably someone complaining about Canon's RF narrow aperture lenses bought your 1963 lens and promptly attached it to an adapter for their apsc cameraI had a wonderful 1963 Leica M 35mm f2 lens. My favourite lens in the Kodachrome years.
That is, before I tried to use it on a digital Leica M. In order to get a picture sharp from edge to edge, f11 was needed. Quickly, I traded this "character" lens for a Summilux 35 Aspherical. If character means unsharp, I happily pass...
And it's absolutely true, pictures can be unsharpened, but not the opposite.
Meyer Trioplan soap bubble bokeh? Some like it, others don't. Just a matter of personal preferences...
Most new lenses from the same brand are simply better than their predecessors (EF vs. RF).
Maybe, since the centre was quite sharp and contrasty. Or, more probable, a lover of "character" lenses...Probably someone complaining about Canon's RF narrow aperture lenses bought your 1963 lens and promptly attached it to an adapter for their apsc camera
Yes, it’s almost as if someone doesn’t really understand what lenses would best serve the current market and yield the greatest profit. I wonder who that is? The company that has led the ILC market for 20 years…or you.I am not sure what they are thinking, or how they can't see that they would sell way more of these at ~$500 and 8oz lighter in a 1.4 version.
