So, you bought a very expensive back primarily based on price, and are frustrated because you cannot figure out how to work the thing without help. People here are jumping in by the boatload to help you, including some dealers who you didn't pay any money, yet it makes little difference to you and you now want to get rid of it.
I find this astounding.
What happened to buying a product and using it. Now you spend in excess of $13K on a camera/back and you still need to spend nearly and extra thousand to get up and running, constant software upgrades designed simply to generate a continued stream of revenue for the companies that sell this gear, not just digital cameras but all digital equipment, sold simply as a way of developing a continuous stream of income for these companies. God forbid you buy a product and are not required to "upgrade" just to get the device to work.
That is exactly the case here: You are not required to upgrade. If you want to use C1 4, then the system requirements are right on the Phase One website: intel Mac and Mac OS X 10.5.6. But you can use a PowerPC-based Mac and C1 3.7, just like everyone did before C1 4 came out.
By the way, what "constant software upgrades" are you talking about? Once it works properly, which C1 3.7 should do with a PowerPC-based Mac, it will continue to work for a long time, with no changes.
I have 10 different film format cameras , and once purchased and paid for require no extra expenditures, other than infrequent maintenance.
Sure, if you don't want to take any pictures.
Btw, why did you sell the ZD camera and buy the P45+?
This camera was not designed for anyone seeking a creative outlet, unless being a tech junkie is in and of itself is seen as a creative outlet.
Correction: this camera was not designed for anyone seeking a creative outlet who is unwilling to read manuals and do any other systematic learning. The creative outlet part comes after you learn the tool. This is the same with all creative tools, from a simple paint brush to the P45+ to CS4.
What really frustrates me is that I am solely responsible for choosing my creative tools without being fully aware of the true/hidden costs.
Who do you prefer to have responsible for choosing your creative tools?
You have to do some digging, this is always the case, whether you buy a Canon or a Phase One. Does Canon tell you on their website that you need a computer to do digital photography? You have to find these things out.
