Oh dreamy lens, you make me feel like a super spy out to secretly capture the expressions world. Thanks to another photographer friend of mine, I was able to use this lens at a past event. Which really just left me thinking, dreaming, and drooling over it. See http://shop.usa.canon.com/webapp/wcs/stores/servlet/product_10051_10051_227563 for all the details. This lens sells for well over $2000 new ... even the used versions catch a fair price. Someday my love, someday!
