Hello
MartinC, apologies for the late response. Regarding your question, I do have canon m50 as well as a backup, and also 100mm L f2.8 Canon. From what I can say, is that I do get good results using the lens. I can't tell you much about laowa as I don't own one unfortunately.
However, if I'm not wrong, the laowa lense are manual focus, where on Canon 100mm you have auto focus, and you can use it for other type of photography. Also, check our
Showcase page, you can find some reviews on these lenses.
K
kzurro or
MinitecaPhotographie might have experience with laowa lenses.
