Few lenses hold a more legendary status among photographers than the 50mm f/1.0L. Even 31 years after it hit the market, it still commands around $4,000 on the used market. What makes it so special? This great video takes a look at the lens affectionately known as the "bokeh beast."

Coming to you from Matt Day, this fun video takes a look at the Canon 50mm f/1.0L USM lens. The 50mm f/1.0L USM was released in 1989, but even in its fourth decade of existence, it easily commands $4,000 on the used market. The 50mm f/1.0L was eventually replaced by the 50mm f/1.2L in 2000, as most pros preferred the latter lens, as the former was more of a show piece — not particularly sharp at f/1.0 and very slow to focus. However, for collectors, owning the world's first full frame f/1.0 lens with autofocus is quite a neat proposition. The one major drawback is that it is focus by wire and far past its service life, meaning if the focus mechanism malfunctions, it will be impossible to focus. Still, it is an incredibly neat piece of history and quite the unique lens. Check out the video above to see it in action.
