Hello, I have been wanting to purchase a D90 ever since it was introduced, but wasn't in a position to do so for awhile. I started looking at them again this summer and read on this website about the D90 replacement coming. So, I waited for the D7000 to be announced - primarily because I wanted video auto-focus. Now that it has, I'm thinking that the cost, complexity, and size of the D7000 is probably not justified by my casual use.
I currently have a D50 which I use for family pictures, landscapes, closeups of the flowers that I grow, pictures of my bird dog in action, vacation pictures, photos of people doing outdoor sports, and an occasional session of "let's walk around and see if we can find something pretty to take a picture of". I use a 18-200VR almost exclusively, because most all of my pictures are taken outside, and I just don't like changing lenses when there is a risk of getting dirt in the system.
I'm sure the D7000 would be a wonderful camera, but I don't know that I would use the advanced features on it enough to justify the cost. Although I like to experiment and fiddle around with the various settings, my wife just wants to pick up a camera that has all the settings on automatic and just pay attention to composition. Also, my wife is very small and likes smaller, lighter cameras. I like lighter as well when I'm hiking and walking.
So I'm trying to figure out if I should buy the D3100 or wait for the D5100 to be released, and here are my questions:
1. What will the likely advantages be for the D5100?
2. How much more will it cost than the D3100?
3. And how long would I have to wait?
I know that all this begs a lot of speculation, but I have to believe that Nikon has to upgrade the D5000 now that the D3100 is almost as good as if not better the D5000. Furthermore, there just seems to be a gaping hole between the D3100 and the D7000 that Nikon has to fill.
