very pleased with this achat.c is a top-flight goal for cheap. very fast and silent pic of the full opening. I used the on 5d mark 2 as part of my work and I am fully satisfied. I find it better than the 50 1.4. framing is tighter but it is quieter it is stronger suffers less chromatic aberrations and is not obliged to close a little to see dive. the big advantage is also c s race in manual AF compared to 50 1.4 the 85 it takes a half turn to go from macro to infinity while the 50 it takes almost two laps !! this detail can quickly be annoying when video with an accurate monitoring of its development it lacks the red liserait for 5 stars
