It does indeed seems work with the moiré reduction on link 1 and 2 the way you did it - and I can also live with that.
I am much more worried about the color artifacts (CA ?) and how to deal with that - it seems to be everywhere once your eyes are tuned in.
It is still there in your moiré reduction 3 image.
Maybe someone here with more experience can give a hint on how to deal with these artifacts (different backs and different software).
Regarding the Contax 35mm - the one I tested was very sharp also at the corners at F11. In my testing the Hasselblad 35, Contax 35 and Schneider 35 Digitar were almost equal. The Mamiya 35 was not as sharp as the others. All tested on F11, tripod and mirror lock up.
I have heard from a rep who works for Phase that at their international sales managment conference a few weeks back they did a simialr test amongst the Mamiya 645 w/ 35mm , H2 w/35mm , not sure about thre contax, but they compared them to a CamboWide with a 35mm Digitar and the results were expected similar to what you have seen.
There is definitly a quality difference between the schneider/rodenstock digital lenses vs the regular lenses from on the 645MF systems.
I have asked for the sample files so they can be posted. It is intersting becuase they also compared H3D w/35mm vs P45 on H2 w/35mm and the P45 image had less CA. The image that was shot with the H3D looked better with their DCA tool turned off.
One of my collegues who just purchased a p45+ was able to take advantage of a worldwide promo that Phase One is doing until the end of the year in which he was able to purchase a Cambo Wide DS w/ 35mm Rodenstock HR lense for $3500 as a bundle with either the P25+ or P45+. Compare that to the list price of a Hasselblad 35mm HC lense at about $3050. He is able to have movements today and a nice piece of glass . No need to wait for that "t/s" lense from hassy that has been talked about for so long and who knows if they will supporrt it with 3rd party backs!
He also had the option of also pre-ordering the new Horseman SWDII Pro, and also if he wanted to could have opted for the 24mm Digitar for a price of $4000.
