Canon EF 50mm f1.2L USM
29 April 2013
Excerpt: The Canon EF 50mm f1.2L USM is a prime lens with a standard focal length of 50mm and the joint-fastest focal ratio in the Canon lens catalogue - a position shared with the EF 85mm f1.2L USM. Announced in August 2006, the EF 50mm f1.2L USM is one of the most aspirational and exotic mass-produced lenses around, although it's actually the replacement for an even faster model, the legendary EF 50mm f1.0L.
Excerpt: This speedy full-frame 50mm f/1.2L ($1,400, street) fills a vacancy left by the demise of Canon's 50mm f/1.0L four years ago. The company's only L-series normal lens, it's the fastest normal AF lens on the planet.
Conclusion: There’s no doubt that the Canon EF 50mm f/1.2 L USM , ( compare prices ) ( review ) is Canon’s best 50mm lens and an excellent performer by any standard. The fast aperture is ideal for work in low light, where focus is fast and positive. As a portrait lens, the fast aperture 50/1.2L is capable of subject isolation via its small depth of field and its ability to throw backgrounds out of focus. The quality of the background blur (“bokeh”) is smooth and pleasing.
Summary: Canon EF 50mm f/1.2L USM is a very promising lens - it's one of the fastest prime lenses available for Canon's EF mount and is clearly targeted at photographers who require that extra f-stop and are willing to pay premium for it. However, the lens did not quite live to all my expectations.
Conclusion: EF 50mm f/1.2L USM The superbly built EF 50mm f/1.2L lens provided modestly sharper images with better out of focus blurring (bokeh) at f/1.4 and f/2 and was much more resistant to flare and internal reflections than the EF 50mm f/1.4 lens. This improved performance comes at the cost of increased size, weight and a greater than 5-fold higher purchase price. The f/1.2L lens did not focus faster or more accurately than the f/1.4 lens in these tests run under good lighting.
Excerpt: For many years, a fixed focal length (prime) 50mm lens was standard for film SLRs. Although 50mm lenses are not nearly as popular as they used to be, there are still many people who want one of these in their kit.
