Why does nobody talk about the advantages of distorted wide angle lenses?Rationally, those two impacts apply to all lenses. What is not rational is the belief some people hold that increased noise from vignetting correction and loss of sharpness from distortion correction apply only or differentially more to lenses that require digital correction.
Vignetting is the easier to understand of the two effects under discussion. The ‘optically’ corrected EF 35/1.4L II has the same amount of vignetting as the RF 35/1.4L VCM. Correcting it in post introduces the same amount of noise.
The situation with distortion is really no different. Any wide angle rectilinear lens requires distortion correction. The wider the AoV, the more correction needed. Digital correction of distortion ‘stretches’ (interpolates) the image data. That stretching is based on mathematical modeling of the lens. If you prefer to be a bit pejorative, the digital correction smears the corners after the image is captured.
Optical correction of distortion also ‘stretches’ the image based on mathematical modeling of the lens, but the correction is performed by designing it into the lens optics. While there is no interpolation needed, optical correction still smears the corners…it just happens before the image is captured. The end result is the same – loss of corner sharpness is similar.
It’s also worth noting that optical correction isn’t perfect, there’s almost always distortion remaining in wide and ultrawide lenses, they’re just corrected enough to fill the frame. Remember the ‘optically corrected’ EF 17-40/4L?
I believe opinions about physical matters should be based on facts. Some of us have the personal view that the earth is flat. It’s not. Digital correction is not inherently worse than optical correction.
Now, if you want to emotionally believe that the best ice cream flavor is something other than mint chocolate chip, you can (but you’d be wrong).
You simply have more real estate in the RAW files for keystone perspective correction in the transform tool in the PP software of your preference!
Try it!

I was pleasantly surprised that Canon marketed the lenses for their effective focal length, not their actual focal length. Imagine the online outrage when the 14-35mm resulted in a 15-34mm range after correction!

So, for the first time ever, Canon will make a fast prime wider than 24mm. Interesting. I wonder how it will match up to the Sony 20/1.8G? The review comparisons will be...interesting.
The real question is, will Canon ever make something that can compete with the 14/1.8GM? And if so, how much will it cost? Considering the "budget" 20/1.4L VCM will be $1700 (vs $900 for the Sony 20/1.8G), one can only imagine what they will charge for a full-fat fast 14mm L lens. The Sony 14/1.8GM is $1600, will the Canon be close to double?

Sony fanbois gonna fanboi.You compared an f/1,4 lens to an f/1,8 lens. And wondered about the price difference?

I compared Canon's budget VCM line "L" lens to Sony's G series lens at the same focal length. You can bet there will be many reviews that do the same thing. The 20/1.8G is an incredible lens and the 20/1.4L VCM will be hard pressed to match its performance.You compared an f/1,4 lens to an f/1,8 lens. And wondered about the price difference?
Personally I will be very interested in seeing if Canon has improved with their ultra-wide prime designs. I don't think they have ever produced a truly excellent ultra-wide prime lens.

If you don't understand that Canon's VCM lenses are their "budget" L primes (a very relative thing with Canon's pricing), and that Sony's "G" lenses fill the same spot in Sony's lineup, I'm not sure what to tell you.
The Sony 20/1.8G is an absolutely incredible lens. I will be impressed if the Canon 20/1.4L VCM can match its performance.

No one can ever match Sony's incredible supreme unbelievable quality.
Canon's VCM lenses are the worst crap ever produced.
How can one even dare to compare them to the absolute summit in optical and mechanical godlike quality?
Eat your heart out, Leica, Zeiss, Canon and co. , Sony rules!
Satisfied, now?

And I think dismissing a competitor's products out of hand without considering the reality of the situation is immature. I've owned and used more different systems than most people and am not loyal to any one brand. I'm unlikely to return to Canon because the prices are very high and the mount is closed. If those things change, I would consider it. I'd also look at Nikon again if they opened their mount up more.
Being blindly loyal to one brand is a fool's game.

There's a difference between "fair" criticism and fanboi propaganda...
I also particularly appreciate posts which insidiously criticize a lens that doesn't exist yet.
Anticipated criticism of competition a sure way to recognize a true Sony fanboi.

Fair criticism of unreleased products?
I guess it's not that easy to do something about a fast UWA with a 44mm flange distance?
Try practice what you preach.

Anyone who challenges criticism of Canon or praise of Sony must be blindly loyal to Canon.
QED, at least in the mind of a Sony fanboi.

Your mistake! As a blindly loyal Canon fanboi, you intentionally misread the charts, not willing to accept the universal truth that a brilliant Sony lens cannot be beaten by a vulgar low category Canon VCM lens.
Don't be blindly loyal to a brand!
I will order this crappy VCM lens myself, being a low-quality fanboi!

No, no, no. The Sony lens is only $900, the Canon lens costs almost twice as much. So even if the Canon lens is better, it's a fail as far as value goes. Oh, ignore the 2/3-stop wider aperture. It's not like there's a full stop difference, it's only 2/3-stop and it's not like the Sony 85/1.4 costs more than double the 85/1.8. No, no, no.Your mistake!
