I'm just a little dumbfounded by how so many photographers are seemingly pushing the big red panic button to leave their beloved Phase/other H system Backs. I have one word for you. Contax. I Know MANY people who you'll have to pry that camera out of their dead hands!!!! To think that your tool is now worthless and that you should jump ship is so narrow minded and sad! You should Buy another body and enjoy 7 years of great pictures, or at least until something BETTER comes along. Moving to the new Hassy is a downgrade in some regards, and lateral for the most part with a few little perks at a very high cost for many. Also, how stupid will you feel when they orphan it with the H4 when they make it all in one like a Canon/zd? Seriously. Your in the same boat again and at that point with most likely a payment equal to buying from scratch with your previous upgrade. If I were to buy TODAY it would still be H with Phase back. The HY6 seems amazing but with no Phase back (and no rotating back) it is a non starter at the moment. Yes, the tides are changing. Yes the Hassy is getting better, and has new software (I hate that scanner software). Yes, leaf is getting better and has the AFI. Sinar too is making improvements and new software in the pipe and the HY6. These are all major threats to Phase, and Im not so sure I love C1 4.0 either. However, if your back is within the last generation or 2 your crazy to think the money you lose to switch will buy you anything more than false hope of non obsolences. The new chips from Dalsa/Kodak can not be that far off if history repeats, and how bad will you feel when you just bought that shinny new Hassy then... WHAM...-50mp at 1.25frames per second and more DR and better hi-iso? I really think the next generation of backs will be a real turning point. At that point Phase MAY not be the best anymore. Just has Nikon made up ground on Canon so Have Phase's competitors. The new chips will be out, every player will have new/newish redesigned software, and the HY6 will be a known quantity ,and perhaps Phase a trick up its sleeve or not. This is merely conjecture here ,but Photokina seems a good time for these things to materialize and that isn't that far off. If ever there was a time (if your already own) to wait then this may be it.
