Experience with digital backs

[hamertime1]

I have the P25 on a Mamiya 645afd and I love it. I do aerial photgraphy and the pictures, resolution, and the zooming in capability are incredible. Customer service is great and they also have a SDK (software developement kit) that they will give you at no charge so you can program you laptop computer to interact with the back.

The P20 is an excellent digital back that you would be very happy with.
It is a square format, that isn't necessarily a negavtive but you should be
aware of it. The quality of files is very high, the battery life is long, the
work flow is easy to learn. They have very good warranties and Phase-One will provide you with a loaner with-in 24 hours should you have a problem while under warranty.

Hello

At first; I'm Dutch, and there will be a lot of grammatical mistakes. Sorry.
Has anyone experience with the PhaseOne P20 digital back? I had a Kodak Proback for a while (on a Hasselblad H1). The quality was great, but the service from Kodak was miserable (I can better say; there wasn't any service at all). I had a Leaf Valeo 17, but outdoors I had every time problems with the portable harddisk. So I'm looking at the moment for a better system. The camerasystem I use is a Hasselblad H1. Is thera anyone who owned a PhaseOne P20 digital back? I can't afford a P25, too expensive, but a P20 would be great too. If someone has experience with this back, please get some comments? Positive or negative, that just don't matter.

Thanks very much

Michael has several reviews on the P25 here:

So far as I know, the big differences between the two are that the P20 has a 17MP square image, and the P25 has a 22MP 6x4.5 equivalent image.  The P20 has a slightly faster capture rate, but the handling, file type output, etc. is the same.

If that's what you can afford, I don't think 17MP is anything to sneeze at.

I have a P25 on a COntax and overall very pleased.  One issue that is a major problem is that the P25 back does not support B mode for long exposures.  As a result you can forget exposures longer than 32 sec on a COntax 645.  This might not be an issure for some, but for low light interior/architectural/night photography, this is a real big issue.  I found out after I purchased the camera/lenses and back!
