Canon's lenses are split broadly into two camps: the standard ‘amateur' lenses and the pro-level L-series optics. The 50mm f1.2 is one of the latter. It's a fixed focal length lens in an age when almost everyone uses zooms, and it costs more than a semi-pro digital SLR.

I've been putting off purchasing this lens for a while because of it's back focus (focus shift) problem which occurs only when photographing at extremely close distance using the center focus point of the camera.

If you are looking for a 50mm lens with beautiful bokeh, good contrast/color at wide open, and you want to use f1.2, for low light photo AND video, this is the one for you.

Beautiful Color; Durable; Fast / accurate auto-focus; Grea Picture At Wide Open; Nice Bokeh; Rugged

Expensive; Sometimes Miss The Focus

I'm a photographer by profession. I've used 50mm primes from Canon, Nikon, Sony, Pentax, Olympus and Sigma. But nothing can even come close to what this lens can do. Pros: 1. Super fast focusing 2. Silent while focusing 3. Extremely sturdy 4. The most important thing. F1.2 man!

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

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 upgraded this lens from my 1.4 for a trip to France where I assumed (correctly) that flash would not be permitted in museums and churches. I am extremely happy with the images captured; I have great images inside the Notre Dame Cathedral in Paris while all those around me were struggling with...

Fast auto-focus; Superior build quality; Super-sharp images

not cheap

"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

Just got this a few days ago and am enjoying it, it's quite heavy, but feels well put together and very solid. Optically it produces great results. Bought it with 20% off so made it very competitive and interest free over 12 months. Delivered as stated and well packed.
