Canon EF 50 f/1.2L lens (mounted on a Canon 5D Mark III) review by Justin Van Leeuwen at Canon Rumors: It’s a pro lens, and with that comes the need for a pro’s experience to handle it.

"I knew why I purchased the Canon 50mm f/1.4 over the 50mm f/1.8; the more rounded (not hexagonal) bokeh, and the slightly better build. That’s a few hundred bucks. The Canon 50mm f/1.2 L is more than four times the price of the 1.4. This is a cost/value factor we often weigh, and I have personally never once been let down by the better glass I’ve purchased, where I have with less-than-the-best. The aperture may be a bit misleading, I don’t consider f/1.2 useful for me, I have a hard time focusing that shallow of depth of field, and while a good camera body like the 1DX or

5DMKIII certainly help, there’s a little left to your own skill to pull off proper focus. Some people just have it while others, like me, work for it. The optics are certainly worth the investment. Though, for the professional shooter who may bang their camera around and find themselves without a lot of choice as to where they’re positioned for the shot by way of contrast and control of flare; the 50mm f/1.2 delivers.

For the average consumer, however, I’m not sure if they’ll see the difference. Since most people are just looking to achieve a shallower depth of field that the included kit-lens can’t provide, the 50mm f/1.8 will do the trick. More discerning buyers can upgrade to the 1.4 and folks with money to burn can grab the 1.2. It’s the best, but not by the same margin as the price. It’s a pro lens, and with that comes the need for a pro’s experience to handle it.

Pros

Build and optics are pro-level.
Great colour and contrast rendition.
f/1.2 gives you lovely blurred out backgrounds.
Relatively small and light compared to most zoom lenses.
Cons

4 x pricier than Canon’s 50mm f/1.4.
f/1.2 is so out of focus that your focus can be out of focus.
Very strong vignetting (inherent in all 50′s though)."
