The Canon RF 14mm F1.4L VCM is Right Around the Corner

Indeed. The image height of the 20/1.4 lens in the same patent is 18.90mm, the corner performance of that lens is excellent. This is the post-correction extreme upper left corner of an image from the 20/1.4 with Dubhe and Merak in the 100% crop (the two scoop-side stars of the Big Dipper that point to Polaris).

As another example, here's a 100% crop from the post-correction extreme lower right corner of an image from the 20/1.4, and most of this image is from the part that was 'stretched' to wider than the original pixel width, as you can see from the full image in DxO showing the output size of 6492 x 4000 from the 6000 x 4000 sensor of the R1.

What does the distortion correction look like without the crop?

Frankly, I don't care at all.
The VCM lenses were all brilliant, just like the 14mm will be. I could compare my excellent Zeiss 21mm f/2,8 to the 20mm VCM. The Zeiss, though optically corrected, didn't stand a chance...

I’m just stating a “fact”, I’m not saying that it is bad.

If the corners are as good as those of the RF 20mm f1.4 VCM, and size and weight are acceptable, I’ll say goodbye to my EF mount Sigma Art 14mm f1.8 and buy the RF 14mm.
