Just got my X100 half an hour ago. First 1800 seconds impressions.
Looks great.
To me it's pocketable, unlike M8.
Falls in hand similar to yet my favorite pocketable EP1+20mm
The optical VF is fantastic. This is the deal breaker over any m43.
It's quieter yet than my Leica MP. Winner here.
To any rangefinder user it's immediately understood, no manual reading necessary.
Now looking forward to some serious picture taking.
What is the issue with the focus?
Don't have access to Reid's page.
I also started using it without reading the book.
However keep an eye on the exposure.
The maximum shutter is limited to 1000 at f2 getting faster as you close down the aperture.
I use Aperture Priority mode it shows the shutter speed in Red, but happily takes the photo and over exposes.
It took me a while to realise what was happening and then I set the Fn button for the 3 stop ND filter option so I can easily switch it on or off.
good luck
