The 20 will be entertaining. EPZ found 8.1% native distortion which is the record value. Can it be called a fisheye when uncorrected, or does that term describe something more specific?

“The Tamron 24mm f/2.8 Di III OSD M1:2 stays a bit short of the optical quality that we have seen from the Tamron 24mm f/2.8 Di III OSD M1:2 ”

I think the latter should be the 35mm.

"... it still feels like an answer to a question that nobody has asked"

The reason for this triplet of lenses is macro capabilities, otherwise they actually don't make a lot of sense.

"The 20 will be entertaining. EPZ found 8.1% native distortion"

Yep, it's huge!

I didn't see 8% but it's bad, yes.

Maybe it depends strongly on focus distance and their use (and testing) case was more conducive to revealing it, who knows. Their finding for the 24mm was 6.1%, so a bit more than what you discovered, for some reason. Even for the 35, they found 1.2%.
