Typical for most L grade lenses the EF 50mm f/1.2 USM L has an exceptional build quality with a dust and moisture proof outer shell and a very smooth focus ring. The lens has a constant physical length but the inner lens tube moves a little during focus operations. The ring-type USM drive is very fast.
Is the 50mm 1.2 worth it?
The answer, for the most part, is yes. The RF 50mm f/1.2L USM is not only incredibly sharp across the frame even at f/1.2, but its other optical characteristics are outstanding as well. At f/1.2, this lens offers what would have been peak sharpness for 50mm lenses closed down just a few years ago.
What is the Canon 50mm 1.2 used for?
