Just another thing to confuse the situation a bit more. [:D]
Ben.
I live in Victoria, Tx where there are no camera stores. I went to San Antonio this weekend and stopped in The Camera Exchange. This was the first time in a very long time I was able to get my hands on some equipment before I buy. The 50mm 1.4 is one I have been wanting to buy but was hesitant due to some of the comments I have read. I got to play with this lens in the shop and thought it worth the price. My wife said, well if you can use it lets buy it. A wonderful woman.
Today I used it at a friends 75th birthday reception. I am very impressed with the results. The focus seems fast enough for me and all shots were keepers. All shots hand held with 580EX on camera with omni-bounce. Here is 100% crop.

Nice detail. I've not been disappointed with my 50mm f/1.4. My keeper rate does vary, but I'm starting to really understand and work with its nuances.
Technical question: how do you post 100% crop? Do you have to do a screen shot once it's at 100%? [:S]

To make one I personally use Photoshop and have a rectangle selected with a fixed width of 800p. Since the forum supports 800p wide, it will be a 100% view on your crop on this particular forum.
To post one you can use the Insert Media tab and upload your photo, but I guess that wasn't really the question [:P] Or is it?

1.2 better until 2.8 is the general census isn't it? Anything past would be better served with the 1.4
Isn't "100% crop" an oxymoron?
ah n'mind - pass me another Jumbo Shrimp please... [:P]

I had a love/hate relationship with the 50 f/1.4 and recently sold it. Stopped down to at least f/3.5 the keeper rate was excellent, and the IQ was often stunning. But that's not why I bought the lens. I wanted a low light powerhouse, yet it is unusable at f/1.4, and at f/1.8 through f/2.5, I feel like I either needed a very steady hand (which I don't always have) or a mono/tripod. Some of my exposures in that range were really quite good, but the keeper rate was frustratingly low.
I replaced it with the 85 f/1.8. If you can handle the additional length, it is, IMHO, a superior lens that produces much more consistent results. At f/1.8 my keeper rate is quite good. And stopped down it is scary sharp, just like the 50. It also feels sturdier.
