Canon's RF lens range has been expanding but some of their earlier lenses are closing in on early classics for Canon mirrorless. One that has been particularly well-received, is the 50mm f/1.2.
When most photographers buy their first camera, they'll usually acquire a nifty-fifty lens soon thereafter. This usually comes in the form of a 50mm f/1.8 and is arguably the most cost-effective lens you can buy when you measure dollars spent against image quality. The 50mm focal length is a staple of the craft and walks the line between a long prime that doesn't capture much of the scene, and a wider prime like the 35mm which is more common in street photography. For all-purpose portraiture, you can hardly go wrong with a 50mm.
The Canon RF 50mm f/1.2L USM is some distance from the cheap and cheerful nifty-fifty, however. There are two striking and related differences: the first is that it is an f/1.2 lens, making it extremely quick and offering razor-thin focus when wide open. This comes at a cost though, with this lens coming in at $2,299. For a new (in terms of not owned by anyone else and relatively recently released) f/1.2, camera brand 50mm lens with autofocus, you are always going to have to dig deep into your pocket. There were some early criticisms on this front when the build quality was questioned, which is mentioned in this video. The barrel is plastic and for over $2,000, some were displeased by that.
Nevertheless, it is solidly constructed and the images really do speak for themselves.
