For the latest edition of LensRentals gets down and dirty with camera equipment, Lensrentals founder Roger Cicala tore down Canon`s new 50mm F1.2L RF lens to reveal what tech and construction is lurking inside.
`Usually, I start tear down posts with a joke about `those of you who are following along by disassembling your own lens at home`,` reads one of the introductory paragraphs of Cicala`s teardown blog post. `Well, no joke today; this is not a home disassembly project.

Near the USM motor, Cicala noticed an interesting tensioning spring, but it remains unknown what purpose it serves.

Eventually, Cicala turned the lens back over and removed the front lens barrel. After a littl ...
