Having gone through an entry SLR to compact superzoom to 4/3 over 12 months, I think I can give this a go.
As for type of photography, the lens is the bigger driver than the body unless u are into pro-photography. In yr case, the wedding is once off, what's after?
Firstly, must keep in mind that my objective was 'better travel pics' than my minature compact. What I wanted was better IQ and a longer zoom to catch those situations compared to my minature compact.
It was a toss between the entry D3000 and the NX10. Took the D3000. Preferred the OVF as I can see lighting situations better than EVF which is always bright.
The first trip worked out quite well. I was in a group and transport was provided, made it easy to bring that n tripod n stuff.
The second trip was free and easy, my travels are mostly this type. Suddenly the cam weighed a ton hanging round my neck the entire day while walking. Pics were great but it was finding it's way into the backpack, not a good way to be always ready and I wanted a bit more zoom.
A soul, i mean cam, searching followed. The compact superzoom looked like the answer to my woes. Yes the IQ isn't fantastic, but a bit of IQ for my neck sounds reasonable. So P100 it is.
Third trip followed. Cam worked great as thought. No neckaches, long zoom, small n easy to keep. At return, on a 24 inch monitor.........it's back to the shops.....after enjoying D3000 quality, kinda hard to step back. Don't get me wrong, it's still a big step up from the compact in terms what you can do and better quality pics. From prints, you can't really tell.
So what's left. 4/3, perhaps the NX10 was the better choice. Settled on the Oly EPL2 for reasons of larger lens choice.
Fourth trip followed. So far so good. Great pics, reasonable weight. Sold the 2 kit lenses n got the 14-150. I've seen places so dusty you'll be reluctant to bring out the cam let alone swap lens and for travel, swapping is also an iffy option.
So what's next? Eyeing the 5100, but the weight question hangs heavy.
