Again, i know most everything about these lenses, except i have no first hand knowledge, and many of you do. Barring it all doesn't fall apart at smaller apertures(and i know it doesn't), i'm really only interested in stuff wide open to f2.8 or so. if i could get away with narrower i'd just use a zoom. how about if i ask this, is the IQ at f2 and below on both lenses crap, decent, good, or great? and that's without cutting any slack. i know f1.2 at 50mm and f1.4 at 35mm is tough, but i don't care. thanks
For portraits, they both work fine wide open. Keep the subject toward the center, because the corners will be softer with significant vignetting, but that is the nature of the beast. With AF, nothing really beats Canon's 35L and 50L wide open.
