What reviewers say

Both reviews find excellent sharpness at f/1.2, unusually smooth backgrounds and substantial construction, but the heavy lens feels front-heavy on their EOS R and RP bodies. They emphasise reduced light transmission and the price premium. Photography Blog considers it a specialised portrait choice; Digital Camera World questions whether some photographers might prefer the standard lens’s more textured backgrounds.
