Bob,
Like you, the 50mm f/1.4 and the 100mm Macro L were on mt list.
I got the 50mm first,...and really like it. It doesnt AF very fast (I'm an "L" user) but for low light
it is nice. Affordable and sharp at f/2 and smaller. I did order a lensalign MK II with mine and found
a -6 autofocus micro adjustment needed on my 5DII coupled with it. great little lens,..
