I was going to take just a D3200 on a trip in September and then I was informed that I might be the only photog at a wedding other than the point and shooters. So, I bought a D2x on the "I want to sell forum," and was going to throw it in my bag as a back-up. Now, I'm thinking that I should buy a D5100. I'm not taking a flash and I know that the D2x isn't good over ISO 800 since I've owned one or two. So, I think that I should just buy a D5100 and throw it in my carry-on as the second camera. But, maybe the D2x would be the better bet. The wedding itself is during the day, but the reception is in the evening. Or, maybe I should bring my flash. Or, maybe I should leave everything else at home and just bring my D3s. I was planning on bringing two AF-S lenses, the 24-120 f/4 and the Nikkor 10-24.
