Nils - Thanks for the test and the post.
I can't tell you how many calls we get and have to tell people to open up, turn down their power packs or adjust their shutter speed. It's good to see some people know this. So he shot at 22, both were done at 22. I'm sure you guys can do your own test at the parameters of your choosing, as dealers we would all be happy to help you do a test of your own.
I think the test with the supplied "kit" bodies is reasonable. They each put their name on a body and sell systems as a "kit" so why not test as is. Any differences might show why one system is better to choose over another for a individual user. If the outcome shows that the Hasselblad H3D - H4D system is better then it might also show someone was right when they developed a new "system" where they could provide better quality. However you need to test and see for yourself and actually see what is the best "fit" for what you do.
Since we are providing full disclosure, I have worked for a dealer in NYC for the last 12 years and 7 years with Sinar Bron before that. We sell Hasselblad, Leaf, Leica, Sinar, Canon, Nikon, and waiting the addition of Phase to our rental department.
