Yeah,
I thought about all those costs, but once I got the base system, 15.000, I can complete step by step.
the most critical are the SSD wich I find the price insane.
I was also aware of the back-up time but it's not so problematic in my workflow.
Even reaching 25-30 in the end, this is the cost of a MF camera+back, and not even the high-end ones. And I know the Scarlet will give me much more.
But for the moment it's saving and who knows...maybe in a few months Canon will release a "Red-Killer" 4K. at 5.000 euros.
