If you have not acquired a P30 already I would suggest getting a P45/P45+. The P45+ is not susceptible to the color cast issues found on a P30 on a larger format system. Like the P30+, the P45+ also allows you to capture long exposures if need be, yet does not suffer from irreparable color casts.
Funny you should mention that, Louis.
510P - if you haven't already splurged on the P30+, unless you're buying off eBay/end user sale, getting to a P45 might not be much of a difference:https://captureintegration.com/product/phase-one-p45-hasselblad-h-mount-3/
This unit is an internally upgraded P45, meaning that while the LCD is the same as the dim LCD from the original P45, the internals have been upgraded to P45+ level, meaning it has tethered live view and is capable of long exposures (at least up to 20 minutes, easily). It's a larger sensor than the P30+, has more megapixels and does not suffer from the irreparable color casts Louis referenced.
Now, I will say I have had a few clients who used P30+ DB's with movements, but very very slight movements is all they could get away with. For a view camera and all the movement options, it's just not viable.
