I own a Nikon D70 with 2 lenses: 75-300mm and 18-70mm. I have always been frustrated with the tiny viewfinder and need to upgrade my kit.
I am considering:
Nikon D7000 (so that I can use my existing lenses)
Nikon D600 (to get a full view finder - this means my lenses need to be replaced as I believe they are not compatible with a D7000)
Canon 7D (only due to a 'cheaper' 100-400mm lens)
I primarily use the camera for daytime shots: Landscapes, wildlife (I live in South Africa), kids. Due to the wildlife trips, I like to invest in a decent long lens such as the 100-400m lens and this is the reason I am considering the Canon switch at all. I think that the D7000 switch would make the most sense as I have 2 existing lenses but the 75-300mm lens is a tad short. But perhaps I should start fresh?
Budget: I prefer the price of the D7000 obviously but if there is a serious case to upgrade and save for the big lens, then I will consider this.
I know it isn't an easy question but appreciate any comments/advice.
