I hear what you're saying and my heart says that I should get the 40/2.8 as just the kind of lens that should suit me. However, I just can't see it displacing the 50/1.2L as my default lens on the 5D - that's a marriage made in heaven! My standard walk-around kit is a 5D+50L, with a 24/2.8 (old) just in case I need something wide. Or, sometimes, a 5D+35/2 (a lovely old-style EF lens that seems vastly underrated) if I'm doing one camera, one lens. I can't see the 40/2.8 squeezing in between the competition for my actual uses. Yet, somehow, that seems a shame because I love the concept
of the 40 pancake.
Still, looking at my shots - and EXIF data on the focal length I most often use with a mid-range zoom - it seems I naturally "see" at about 50mm, so the expense of my much-used 50L seems justified. I do dearly love the results - long after the pain of the $$ outlay has receded. And I don't begrudge the size/weight at all. Everything about the 5D/50L combination feels "just right" to me
I know others' preferences differ but on my experience I'd recommend buying the 50/1.2L to save yourself from working your way through the other 50s first.
I am enamored with the 40mm. Aside from being small, light and cheap, I find it to be the perfect angle of view for most family photos. And most importantly, the 40mm is just so cute!
Given the distance that I usually stand from my subjects with this lens, it is not too close to introduce linear perspective distortion issues with people (well, just a little) and close enough that I can position a flash where needed in relation to the subject(s). At f/2.8, I get great results and enough of my subject in focus.
Sure, f/1.2-1.4 will give you great subject/background separation with full body shots or smaller objects that need less DoF, but for people photos I like to get in close where f/4+ is better. If I do need less depth of field, I will break out the 50mm or, preferrably and if possible, the 85mm.
