Canon RF 14-21mm f/1.4L USM one of the “crazy” lenses coming next year [CR1]

[Canon Rumors]

Canon has said in various EOS R and RF mount presentations that the RF mount is going to allow them to make some “world’s first” type of lenses. We’ve already seen proof of this in the RF 28-70mm f/2L USM,
We’re told that an RF 14-21mm f/1.4L USM is currently in advanced development and will likely be one of a couple of world’s first lenses coming for the RF mount next year. After speaking with the source, we did confirm that there’s more to this than just a patent published here back in November.
The same source said that a “crazy” prime lens will be coming for the RF mount next year, but that the focal length and speed were unknown at this time.

If the specs are a RF 14-21mm f1.4 L , it's going to be seriously expensive! My bank account is fearing its arrival already!

 

[6degrees]

Exciting!
But how much it will cost?
If it is 18-28mm F2, already good enough.

 

[Proscribo]

My not be too bad. A 14mm f/2.8 aperture is 5mm wide; a 1.4 is 10mm wide. You can think of it as double (which it is) but it's also only another 5mm. For Americans' that's 0.2".

If it just was this simple with super wide angle lenses. The problem isn't directly the aperture size, it's that a single surface of glass can't bend the light enough (damn you, physics!), so you need to do it in multiple steps.

Some feelings can only be expressed by emojis.

Size, weight, cost...sure, I'll want to see each of those, but this will be a lens I will be very happy exists in the Canon portfolio....and it may be even end up in my bag.

 

[Punio]

Next year is going to be expensive...

AFAIK, there aren't any primes that fast for any FF camera, which would make such a zoom really amazing.

People would still complain Canon isn't innovative, though.

Problem is, those people only look at the mistakes.

 

[bergstrom]

the dream would be a canon ef 24-105 1.4, but thats not gonna happen.

 

[maico]

The patent lists the length as 191mm, almost as long as the EF70-200 f2.8 which is 199mm !

F-stop as f1.55
14.5mm-21mm

 

[1Zach1]

Well I’m already saving for the 15-35, so I’ll just keep saving because I’d rather have this.

It’s more about the perceived ”innovation gap” between Canon lens division and the camera body division. But it is definitely a deliberate strategy from Canon’s part, at least partially. One reason Sony has had to go all in with body features is that (besides being a market underdog) their lens selection was (and still is) not there.

14-21mm f/1.4L. Hmm... I'm guessing an MSRP of $1,000 per pound.

 

[fentiger]

more like $1000 per 1/3rd stop below f2.8

 

[slclick]

Super Wide Zoom at 1.4... WOW!

(who then proceeds to put it atop a tripod, stop it down to f/8 and use a trigger...hey, at least I didn't have to turn off a mirror from flipping, lol)

 

[GMCPhotographics]

It sounds like an epic lens in every possible description. It could be the last word in wide angle fast lenses.

 

[stochasticmotions]

Sounds like a very interesting lens. Could be great for astrophotography but it will be very challenging to make a zoom that strong across the whole range. Looking forward to seeing if they can do it.

 

[zonoskar]

The patent lists the length as 191mm, almost as long as the EF70-200 f2.8 which is 199mm !

Patent measures from the image plane, right? So subtract the flange back. That would make still 170mm: quite large.

I wonder what th einsane rpime would be. Could it be a 35mm f1.0 ? Pretty please....

 

[tron]

I am just fine with my Sigma Art 14mm f/1.8
I have enjoyed it the last summer going from 10000 ISO to around 3200 for landscape astrophotography. The difference between 1.8 and 1.4 does not justify the extreme cost. With the difference one can get the 16-35 2.8L III (or a similar RF in the future).

The patent also lists a 12-20/2 lens of about the same size. While long at around 190 mm length is not to change during zooming. Key element of the patent is a resin lens element (element OE in the patent) which is placed in a sandwich between two glass elements at the image plane end of the lens. Element OE is described as being of low dispersion and extraordinary dispersion so it might not be the cheapest piece of plastic ever sold.
