BUY IT NOW, save yourself from the Canon 50mm lineup and get even somewhat better quality than the prestigious 50mm "L" lens... Canon's is good/great, but after some review this one has the upper hand in 50mm (only this range, "L" is preferred on all others for me)... can't wait for the 5D MK2...
Inexpensive; sharp at 1.4; and great background blur; blows away my former Tam** SP F2.8 lens; ultra fast focusing on my 50D; a great pair for portraits; made my photo shoot go easy the other day and it made it hard to pick which photos to use; THE WERE ALL GREAT!!
its not a 1.2; ummm
