Jeden z klientów BHPhoto dał taką recenzję RF85/1.2:
"Over time I had quite a few 85mm lenses. My favorites were the Canon 85/1.2L II, the Otus 85 and the Sigma 85 Art. This one beats them all. It has sharpness of the Sigma, amazing bokeh of the 85/1.2L II and CA-free image of the Otus. Plus it has something all three lenses are missing: very fast AF (the Otus is MF, but you got the idea The is nothing else to wish for, maybe just a stabilized high-res body from Canon?"

To po części odpowiedź na pytanie dlaczego akurat to szkło.
