Answer by Cameron Frost:
There are some really good deals on used kits right now. I think you could pretty easily get yourself into a Phase One P40+ kit in the $10k range. There are also a lot of affordable financing options and tax incentives for your business (such as writing off the entire purchase the first year), should you decide to take the leap.
I recently purchased a Phase One IQ140 system to use alongside my Canon 5D mark III. Both are incredible cameras and each have their pros and cons. The Canon is faster, better under low light conditions, shoots video and is quite a bit more affordable. The Phase One has superior image quality (due to the larger sensor size), retains much more detail in the highlights and shadows and can flash sync at 1/1600th using a leaf shutter lens and Profoto Air system.
If you're interested in learning more or purchasing a system, contact my rep, Chris Snipes at Calumet in Ft. Lauderdale and I'm sure he can help you find what you need.
