I had the D800E since it came out, I was one of the first to get the 'E' in Ireland afaik. I bought a 24-70 2.8 and the 70-200 2.8 VRII along with, and added an 85mm and a 300mm later. I did love that camera for a while, but found I was getting more agitated anytime I just wanted to go shoot casually. the bulk and heft, the attention it drew when I just wanted to do a bit of street or even landscape. I'd have people pester me with silly questions like "what paper do you work for?" or "DO you do weddings? My brother's flatmate's third cousin Nigel is getting married in 2 years ...." I don't get that anymore, people see me out shooting with this small-ish set up and just leave me to it. Nice. Well, it still happens the very odd time. I was down by the river last week doing some macro and a woman stopped on her walk with her dog to ask me was I the guy who does the photos for the Boyne valley Facebook page ...
Ideally, maybe, I should have got the XT-1 and a couple of primes to go along side the Nikon, but I also had medical bills, a house move underway and that included new furnishings .... it was one or the other gear wise. I've never been really sorry for my decision, the XT-1 has made me happy about photography again. It feels more like it used to, before I almost ruined it by trying my hand at going 'pro'. The wedding scene is really not for me, shooting for others outside of family in general is not really for me

so I'm happy to have it back to being a full on hobby, and if I only ever had one camera and lens I know I could make it work, whatever the make or model. Still no harm in wanting or desiring fancier gear. I think we'll always do that no matter what we have.
