While Canon had a spectacular 50mm 0.95 and an only slightly less spectacular 50mm 1.2 in their LTM lens line-up, it seems the most popular of all those 50mm lenses is this compact and affordable f/1.4 version. Over the years this lens became somewhat of a legend, but is this actually justified? Let’s find out in this review.
This lens will be reviewed on the 42mp Sony A7rII and the 24mp Leica M10.
