Wow, congrats Edward! Glad to read that operability doesn't seem to have changed any compared to the preproduction lenses Zeiss had at PPE last year. My impression then was also that the lens had a better feel than my other ZMs, particularly the very smooth focus. Also glad that you're finding wide open focus to be accurate with your M!
Regarding viewfinder blockage - it is a factor in this lens, but also with others, including a number of Leicas. My workaround is generally to shoot with my right eye to the viewfinder and keep my left eye open. The left eye's peripheral vision will somewhat fill in the blocked view of the right eye. But of course, it's not a perfect solution, nor a good one if you're a left-eye shooter.
Looking at your images, I'm also a bit on the fence about the background rendering in these situations. I suspect I will like it better in situations where backgrounds are less busy with specular light sources not considerably de-focused. It's probable that the 35 Sonnar in the RX1 remains unmatched. Otherwise, as you stated, in the plane of focus it looks modern and clinical.
Rocky/Adam - I may still consider a Sirui travel pod. We'll see how it goes with the FLM. The model I got is the CP30-M4S, which packs at about 47cm/18". I'm also getting one of their monopods and when discussing this with the distributor, because I needed the monopod to fit inside a Pelican 1510, after he physically measured the monopod, it was slightly shorter than the stated specs. Therefore, there may be a chance the tripod is slightly shorter, too. ~18" may be good enough for my needs, though its girth may be more relevant to how bulky it feels while out wandering around. It would have been a lot easier to make a decision by looking at these in a shop, but the local options just aren't many. The Leica Travel Tripod is the same specs as the FLM CP26-S3S. Interestingly, at $500 US, it's very competitively priced with FLM's USD pricing. In other words, there doesn't seem to be an insane Leica markup for the rebranding.
