Godfrey,
Ah, a 56 x 56mm sensor - if only! I think the main benefits of the SWC and 38mm Biogon would be lost on the smaller sensor, although this would not prevent me from having fun with a 100 Mp BSI sensor if/when it does materialize in a CFV-type back. I actually acquired and later sold a newer model SWC/M to use with my IQ160 (since sold as well). It turns out the early vintage SWCs have a small ridge built into the light trap that prevents the Phase One backs from seating. But I will never sell my old SWC, regardless...

If I had any faith that a full 56x56 format back which would work well with the Biogon 38mm f/4.5 T* lens would be available at some time soon and at a price that I could afford, I'd not have sold my SWC. Sigh; I don't. I used the money from selling the SWC to help fund the 907x and XCD 21mm lens, and I'm happy with that combination.
