Yes Frank,
I use a Hasselblad 503Cxi with a Sony CMOS sensored Hasselblad CVF-50c back. And it works well if you are in for "Slow Photography", less well when your 4-weeler Mercedes bus is surrounded by thousands of migrating sheep driven by tens of Iceland hourse mounted "sheep women/men". Then "Bladaren" is bit on the slow side.
I shoot tripod mounted. Guess exposure and change according to histogram. ETTL, never whiten a highlight (nearly). The sensor allows you to lighten dark areas nearly at will. Always shoot at base ISO 100. Live view works somewhat.
The setup is rather rain resistant. Two Canons failed in the group. Not Leicas or my Hasselblad. You have all weathers during a day on Iceland. So just wait for the light, it comes. Don't hurry.
And the digital back costs as a long Nikon tele lens but the lens I shoot #5 with (Sonnar 5,6/250) costs around € 1100 second hand.
If you use exposure times longer then 1/8 sek you have to connect the flash sync nipple on the lens with a cable to the back or dive into the sparse back menu. Your choice.
As for weight, when in a photographic flow you forget it. I am half fit 67 and carried my four lens system all day. That the legs got a bit stiff afterwards also affected shooters of other ages and camera systems.
And yes Frank, the organ of Reykjavik´s Hallgrimskirkja is quite impressive but more suitable for a Leica shoot. No tripod there. Will appear under appropriate heading.
