patrickjames....i'm already getting the 85 and 135 tomorrow.
elekm....i do shoot quite a bit of low light in alleyways and under bridges so it would come in handy. mostly though, it has a brighter viewfinder than the 1.7 and ontop of that has a closer focusing distance. since i can probably sell my 50 1.7 for the same price i'm buying this 50 1.4, it's pretty much just trading in one for the other. but thanks for the advice, because i keep that "if you don't need it, why get it?" frame of mind when it comes to spending a lot more on something "new".
speaking of which, does anyone have experience with the 28 f2?
