the Canon 50mm 1.2 L lens

For a long time I’ve been considering buying the Canon 50mm 1.2 lens. The 50mm focal length has always been a favorite of mine, and some of my best images have come from 50s. Here are a few commercial images I have shot recently with either the 50mm 1.4 or the older metal-mount 50mm 1.8 lens:

In my research I found a number of helpful reviews of the 1.2 lens as compared to the othe Canon 50s. Here are a few:

Here is a test gallery which someone posted, and i think it shows some cool images shot wide open:

Of course I won’t be getting rid of my cheaper 50mm lenses, because I love the flare that they produce, and while the 1.2 lens looks great, it produces much less flare. And flair, at times, is just what I am looking for:

I will also have my hands on a 5D Mark II shortly and I will post notes on it as soon as I can.
