Title: Lens recommendation for Cambo WRS 1200 and Phase One IQ3 50

I would look for:

32mm Rodenstock
40mm Rodenstock

Both offer good shift and rise fall with large image circles. 32mm would benefit from CF on the 50mp back.

28mm Rodenstock
23mm Rodenstock

Both have 70mm IC. Neither offer much movement 5mm max. Both need center filter for best results.

35mm Schneider

Very limited movement needs center filter.

43mm Schneider

Great IC. Great range of movement. May need CF for best results.

Note Schneider no longer markets their lenses. But can be found used.

regarding phase one digital backs, are there different cambo mamiya adapters for IQ2 and IQ3 series backs?

Only difference should be a larger opening for the pins at bottom center of digital back.  IQ2 did not have power share, IQ3 does, and has 2 or 3 more pins. 

I know Arca did a different Mamiya plate for their cameras that had a larger opening.  Many photographers however just used the same plate, and depressed the pins.  No one reported any damage.

I would suggest working with a knowledgeable dealer that can provide you raw files from various back+lens combinations, and more importantly, arrange for you to rent the systems you are considering with the rental counting toward purchase. If you're in the USA we'd be glad to be that dealer.

I would go with the IQ 350.

The 260 really has no advantage over the 160. Just price a 160.

It can’t get close to a 1 hour exposure.
Noise is no better.
WiFi less than stellar.

Besides the crop factor I can’t think of any disadvantage for the IQ350.

I have owned both the 160 and 260, for me the 260 was a financial mistake. Never lived up to the promise.
