Unfortunately, it doesn't look like a single body will be able to fulfill all the types of photography I see myself interested in.
As I said in a previous question my main interests for now are:
- Pictures at parties and other environments in low light condition.
For these kinds of pictures, a full-frame body such as a 5D Mark II excels.
But those main interests don't rule out other types of pictures such as sports for which a 7D would be more appropriate.
I've seen that some of you guys have a second body or a spare body.
Do you have different bodies for different kinds of photos? Or do have (or plan to have) a second body that identical to the first one only for backup purposes?
