It's not that the 5100 is a bad choice, it's just that 6 months later when you have significantly explored and dazzled yourself with the great quality pics, you would be ready to experiment and have more control or look for more details.....and then you'll say "hmmm, wonder if I I had spent those several (350) $$hundreds more for the 7000....."
Hope you got the 7000.....I know that's the one I'm saving for
