There are so many great cameras out there. I think DSLRs are currently the best value right now.
Nikon F Full Frame DSLRs
My favorite DSLRs for photography.
Canon Full Frame DSLRs
The most popular full frame DSLRs. I think several are excellent values, such as the 5DS, 5D mark II, and 5D mark III.
Nikon F APS-C DSLRs
Combined with DX lenses and the price to performance is the best you can find for photography.
Marketing jargon and elitism are as big of a problem as the overwhelming number of choices out there.
There are an overwhelming number of camera models to sort through.
“Flagship” professional cameras have aged significantly better than swaths of newer entry level bodies. They will have additional features, we likely be weather sealed, have superior specs, customization buttons, and accessories.
