Oh, my God! Rokinon 21mm f/1.4!

I didn't know this lens until I came from you. I like the 35mm focal length very much, but the aperture of canon22 does not meet my requirements. The picture quality of Viltrox23's largest aperture is too bad. Rokinon 21mm f/1.4 is exactly my dream full-frame 35mmf2 lens!

The information you provided is very helpful to me. Unfortunately, I found that China does not have this lens for more information, and it is not sold. Due to strict epidemic prevention policies, I can't even buy it from Amazon.

My 2 cents? I've noted many bans on products, even in the states, for "pandemic" reasons, appear to be trade-war related.

It's notable that Rokinon/Samyang are produced in South-Korean; the ban in your case sounds geopolitical.

Wish I could recommend an alternative, however I'm unaware of another strong 35mm equivalent other than the Rokinon (Samyang) 21mm f/1.4 for EF-M. I don't see the trade-war issues subsiding as they were here before 2019, the "pandemic" just gave countries good-sounding reasons to ban other countries goods that they always wanted. In your case, you're victim to lack of domestic produced alternative of equal quality.

You could have a look at the new Laowa 25mm f/0.95; 25mm isn't 21mm but it's fairly close.  I believe it's domestically produced (China), however I've found Samyang gives a unique rendering of both colors and bokeh. The Laowa sounds promising on paper though as the optical design is a double gauss; gives traditional bokeh rendering vs the more modern "cookie jar" lens designs that favor sharpness at the expensive of bokeh rendering. The Laowa 25mm 0.95 notably lacks special lens coatings which give the Rokinon/Samyangs not just flare protection, but very strong contrast resolution. I think that's going to be your best bet though. It's likely going to perform better in low light, produce more bokeh, sharp, but color and contrast rendition is the question mark. It's APO though, that's unique, you should get some extra bokeh-oomph.

Hopefully it's cheaper for natives though; that lens is a bit pricey for crop.
