OK... Some random first impressions, no real order to any of this...
A solid, well built body. Has a feeling of precision to it married to a slightly "industrial" feel of the casing. When I first got it in my hands a few months ago, my opinion was that it was less elegant Barnack SLR.
Now that I have shot the first few frames, that initial opinion has changed.
First, it is a bit odd to load, not so different than the period Leicas. No, you don't have to trim the leader, but removing the take-up spool definitely makes life easier. The broad open back helped as well. The first thing that I had an issue with is the 45 finder. Feels natural on medium format, like a Hasselblad, but certainly odd on 35mm. It took a while to remember to look down. Secondly, the release on the front of the body is difficult to get used to, but does seem to offer a bit of stability regarding one's grip. Lastly, compared to my RF cameras it was a bit discomforting to watch your composition disappear as the mirror rose, again much like the Hasselblad.
I guess in short, my initial impression that it would be akin to a Barnack SLR, has been changed by the overall feel and use -much more like a SLR Hassy in 35mm, had they ever made one.
