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

Good: Solid build. f 1.2 . Best bokeh. Quiet. Bad: Not sharp as other lens. Price. A little heavery.

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.

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.

Bit out of my comfort zone with a prime lens for weddngs but I thought I'd try the 50mm 1.2 out and oh how impressed I was and glad I've got a prime lens - still got a couple of zoom L lenses and they have their place for weddings, especially the 24-105L.

The background blur is the best

Sharp as a tack - even at F1.2 - incredible bokeh thats 2nd to none - a lens that TRULY delivers what a series piece of craftsmanship should.

"When using a narrow DOF setting you have to be careful as you could end up with part of a person face being in focus and part blurry. However that is part of owning a lens like this. Once you get to know just how low an aperture setting you can use - the results will be excellent.

Lens arrived quickly, and it has met my expectations. I love it.
