As the title of this thread says, our company finally is moving away from roll film. I would like some info on replacing our Mamiya RZ67 with a DSLR. I do have requirements: PC sync for external professional flash unit, capable of providing an image at least 9" x 12" at 300 dpi, full manual settings option, high quality lenses and choice of focal lengths, FireWire if possible, and durability. I have looked at the digital backs for the RZ but are too expensive for our budget. This would be used in factory settings, outdoors and some studio. Any thoughts, opinions, would be appreciated.
