I've been a photographer since my teens, I'm 25 now. Instead of doing what I was good at, I went to college for a useless major and stumbled around the job market until I ended up taking pictures for a living. Right now I work for a studio filming children and we use Nikon D60's. I've been doing this for a bit now and am very comfortable with the D60 and have one myself. This fall I've decided to go to school and learn more about my craft and we're being required to buy a DSLR. Particularly one with video function(from what I've been reading HD would be ideal) which one of my classes will need. The D60 does not have that function, thought it still works beautifully. I hear there's good bang for the buck with Pentax. I don't know where to go. I'm really quite comfortable with a Nikon but I'm very limited on funds. I'm at a loss and thought I'd ask people who know their tech. I'm afraid to switch from a camera that I know but I need something new that's not going to cost me an arm and leg. Will it be easy to be switch from Nikon to another brand?
