Congrats with your newest acquisition, Steve.
You'll enjoy it.
As if you didn't know that ...
Remember that depth of field is 'acceptable' unsharpness.
'Acceptable', because it is assumed that you will not see that things aren't really sharp.
A rather risky assumption.
So better forget about depth of field and preset, DOF-based focussing, and try your best to guesstimate the distance to your subject and set that, each and every time.
Anyway, i think the SWC is indeed overrated. Only slightly, but still overrated.
The lens is great. Low distortion. And it's sharp.
It's great disadvantage is that viewing and focussing thing.
To get the best out of the lens, there's no way round accurate focussing. What good is a sharp lens if you are going to rely on 'acceptable' unsharpness?
And you can indeed focus the thing accurately, if you put a groundglass back on it. But then what you are doing changes rather drastically. No more quick, candid photography.
And framing too is rather difficult. Like with all non-reflex cameras, you don't get what you see through the viewfinder. There is a parallax-problem (though small) and the fields of view of lens and viewfinder aren't 100% the same. The lens obscures a good part of the bottom edge of the viewfinder image to boot.
Sounds bad, but it isn't really. But real it is.
This too is solved by using a groundglass back.
There is another answer within the Hasselblad system to these 'how-to-solve-these-issues' questions, besides using a groundglass back, and that is using a 40 mm lens on a reflex camera.
The retrofocus lenses have more distortion (though still not too bad) and are just as good as the Biogon in every other respect.
But don't let that all deter you.
The SWC is still a great camera. And not at all difficult to use.
You get used to the quirks, and learn how to guesstimate the distance to set, no worries.
But to get the best out of it, use a tripod and a groundglass back.
