I wouldn’t exactly call the 35-90mm a walk-around lens (it’s very large and heavy) but YMMV of course. The 35-90mm was my go-to when I had the H4D-40. I sold it when I went to the X-system but I’ve thought about getting another as I loved that lens.
There are some reports of X1D/35-90mm users over at hasselbladdigitalforum.com. “Good feel” is subjective but it works as it should based on those reports. You’ll want a tripod collar for the adapter due to the weight. I believe AF is now supported with the XH adapter and the 35-90 (id check with Hasselblad support though), but as with the HC lenses, only the newer 35-90mm lenses will autofocus (they need a certain firmware version - I forget which one). One plus of the 35-90 is that it is available now, and I’ve seen older lenses pretty cheap (<$3k USD used).
Also, not that it matters a whole lot but FYI the upcoming XCD lens is a 35-75 not 35-65.
