On the flipside if you know the people well, and they realise that they will get what they pay for (I assume you are not charging the close to a grand wedding photographers often do?) you should be able to shoot with a basic SLR and a film backup.
I did an aunts wedding on a Nikon D200, a 18-70mm f3.5, and a SB-800 flash unit. The backup was a Nikon FE with a 50mm f1.8 prime, and they were more than happy with their results
That's exactly it. If I had the cash to go buy two bodies, and several fast 15-90 lenses and a few quick zooms, do you think I'd even post?
I've been getting by with my Canon A610... I beg of you to go look that camera up and see the limitations I am under...
I didn't ASK to become a semi-pro photographer... I merely started showing off my flickr to a few friends, and it grew... now I get calls EVERY DAY, and YES I have turned away about 50% of the jobs offered, because of a lack of equipment.
However, this is a friend of a friend who was going to make their poor old mother in law with her digital camera take the pics. They hired me, and paid me, to take some practice shots on the beach of them (engagement photos), and after seeing the results, hired me to do their wedding... with the understanding I would be using my A610 Canon.
However, I am starting to take this seriously, and since I have a day job, two kids, a wife, rent, car payment and blahblahblah, I have to buy my equipment in PIECES...
So that's why I asked. I am not someone with a "DSLR who thinks he can do it" just because I spent 500 dollars on a camera.
I apologize if I sound snarky, look it up, but I KNOW already what I would LIKE to have for the wedding... my question is... what are the bare necccesaties.
Oh, and I know I'm not the greatest, but you can view my flickr:
