Shaken, so blurred
I've not much used my 50D for high-ISO shooting, beyond a few test shots. It somewhat out-performs my old 30D at ISO1600 (or 3200) when downsized to the same pixel dimensions but, IMO, isn't anywhere near as good as my 5D at either setting. The 50D has "expansion" high-ISO sensitivities of 6400 and 12,800. However, unless you're into surveillance photos they're not very useful. I strongly suspect they are "marketing" settings, designed to tick boxes in comparisons with Nikon offerings, despite being not nearly as good as the latest Nikons at those settings.It will be interesting to see how good the high iso performance of the 7D is. It doesn't really appeal to me, but when the 50D was launched the fanfare suggested that it would outperform the old hack 5D, but the sample pictures were les convincing in my view. Does this tally with your experience?
I have to say that the 5D looks outstanding value these days - available at a reasonable cost with 5,000 to 150,000 actuations.
For the original poster it depends on what your friend wants and does. If it's just a business decision and he can live with something not the odlest a 5D and 24-105L or 28-70 2.8L will deliver great image quality and leave plenty of change ofr a couple of primes. I like the 50 1.4 as a good start.

I agree with you about the original 5D being good value these days. I bought mine at an excellent price, from someone urgently wanting to upgrade to the mkII. I had thought of just turning it around on eBay for a quick profit but found that it works so well with some of my EF primes that I never quite parted with it. In fact (and despite the lens size) it works so well with the 50/1.2L that they seem almost welded together.
