I'm about to start a project where I'll be on the road a lot, filming manual labor. I want a small camera I can roll out with so I'm looking for a DSLR. My main camera these days is an HMC-150 and I still want to use it for interviews and other elements of the film. So, I'm looking for a DSLR I can use with the HMC-150 where the difference between them wont be so big. What DSLR might I want to consider using?
