"If I seem edgy, I want you to know, I never meant to take it out on YOU!"I haven't purchased the 50mm f/1.2 yet, but that's why I'm reading the reviews by those who have. The conclusion that I've reached is that MOST don't know what does what. First, there is NO SUCH THING as a "Narrow DOF".

Low Light Capability

A Bit Of Over-kill For Me

Pros: Durable, Fast / accurate auto-focus, Strong Construction, Consistent Output Cons: Other thoughts: I bought this lens for portrait photos mainly, I love this lens,it gives beautiful results, I borrowed a sigma 1.4 50mm prime lens from a friendbefore purchasing this one and the canon is a bit...

I've had this lens before and as soon as I sold it I began to regret it, so I purchased another one. Aside from its ability to capture very low light exposures, this lens excels because of the "look" it renders. It was designed to be shot wide open and that's where it shines.

perhaps the best lens in my kit will certainly be putting it to some use over Christmas new year

Wow All this stuff about cameras and lenses needs some clarification, and here is why. I use this 1.2 prime with a Canon 7D camera. I get great results. If you set your focus to manually choose placement/ auto, you can do some cool stuff, like have three people in a row, and focus on one- the one...

Speed low light performance and beautiful colors
