LensRentals pubslished the Canon RF 50mm f/1.2L USM lens teardown that shows off how well this mirrorless lens is built.
The teardown of the Canon RF 50mm f/1.2L showcases the lens for the Canon EOS R system. According to test results, they were a bit overwhelmed by Canon’s latest optical masterpiece.
From Lens Rentals conclusion:
The R lenses are not only entirely new optics, they are also largely new electrical and mechanical systems. There are a lot of different things in here that we haven’t seen in any Canon EF lenses. Some of them we should have expected, like the increased electronics going to the control ring. Others we don’t really understand yet, like the tension spring in the ring USM motor or the increased electrical shielding. […] We also saw lots of new stuff we don’t completely understand yet and a level of complexity we weren’t expecting. […] the RF lenses contain some new technology they [Canon, editor’s note] haven’t used before. There’s a lot of engineering that’s gone into these. Things are different inside here. As we’ll see in the next teardown we do, some of that is carrying over to at least some EF lenses. What does this mean? It means Canon has invested very heavily into developing the lenses of the R system. This level of engineering didn’t all happen in the last year, they’ve been working on this for quite a while.
