As professional photographers, full frame sensors are a 'must have' regardless of choice of camera. However, 5DMIII and 6D users will be able to tell you that sometimes the cheaper option ain't so bad! The steep price of the 5D MIII can often scare off those entering the professional camera market.
We've thrown together a bunch of things that great about the 6D:
- 20% lighter than the 5D
- quieter shutter
- built in Wifi and GPS
- equal functionality of the 5D (minus a few bonus features.)
- full frame sensor(pretty much)
- live view
