I currently have a Nikon D5000.
I have the opportunity to purchase a Nikon D90 (body only) as a second camera.
From what I understand, the D90 and D5000 are fairly similar.
If I do purchase a second camera, should I purchase something similar to what I have or look for something different?
Being somewhat of a hobbyist photographer at the moment, do I really need a second camera?
Perhaps an odd question, but not sure what to do.
