Funny thing is I'm planning for my big day late next year myself. So no, I wouldn't give a flying hoot about what camera he's using. What I will care about is his past work, portfolio, references from former customers, deliverables, contract, etc.
You obviously haven't witnessed how "pros" in less fortunate countries go about. There was very little correlation with the work they produced and the gear they used.
On another note, I just came back from a holiday to the greek cyclades a month back. On one of the more artsy islands (Mykonos), I visited a well respected photo studio, famous for award winning portraits. They had all the diffusers, strobes, etc, the necessary equipment. I was expecting to see nothing less than a digital back Hassy (LOL). But no, she was using a Canon G series digicam. Yes, it did put me off a little at first. But one look around in the shop at her displayed work was enough both to dispel any discomfort, and to feel ashamed of being easily impressionable.
