Please Canon, an astrophotography capable RF lens to compete with the Sigma 14mm f/1.8. This lens isn't quite wide enough for optimal nightscape shooting IMHO.
I don't like 14mm on Milky Way... its too tiny without good resolution for stars.

I think 35mm is a good compromise, but you have to use tracking. But you get far better details.
Its the EF 35 IS, but it has coma with 2.0 too, so i have to use f/3.5. But then its very good. And I use this lens for much other photos too, its not a one-trick-pony like a 14mm 1.8... But your option might be another... no problem.

The difference in focal length, according to the patents, is 2.68mm. Personally I don’t think that is enough of a difference to need to buy both lenses, so I asked. I still don’t.
Yeah, I know, but what are you gonna do? That doesn't matter to some.

Fast, Wide AND small & light? Yes please.
I would contend that 3 of the 4 is good enough for me (remove the fast). If you want fast as well the only possible way would be with heavy software correction or a curved sensor so optics become easier to design.

It would be great if Canon is able to put out some lenses like Laowa, but with AF as those lenses check every box except the AF.
