Kevin,
Thanks for writing what I think is the best LuLa article to date this year. Like you, I started with the wonderful X-Pro1, which is still in my bag and which I use frequently, especially with the Fuji 14mm and 23 mm primes.
The X-T1 is the more versatile of the two cameras, as it's EVF provides greater and more useful functionality with the advent of the really fine Fuji zooms. Like you, I shoot with the 18-55 a majority of the time, and occasionally with the 55-200. I will be getting the 50-140 once the motorsports racing starts up again in 2015, as I do professional motorsports photojournalism for a racetrack in Northern California. Additionally, I really like the enhancements the recent firmware update brought to the camera; Fuji brought significant new enhancements with that release.
Your thoughts, experiences, and conclusions about the Fuji X-T1s design, operation, user interface parallel my own exactly. As someone who learned photography with an Olympus OM-1 and manual focus lenses, I love the rotary dial and aperture ring control sytem. IMO, the X-T1 is fully capable professional workhorse with an ever expanding set of beautiful lenses to provide a very high level of performance in a wide range of use scenarios and applications. I look forward to them working with Metz to bring a proper TTL flash system online, and the implementation of the Fuji X Professional Services (FPS) in 2015.
I also own and use the very fine Olympus OM-D E-M1. I principally use it with the excellent Panasonic f/2.8 zooms, the 12-35 and 35-100. But like you, when I reach for a bag these days, it's the Fuji 90% of the time.
Today I will be putting up some landscape images I've taken with the X-T1 this year in another posting, but here's one from my trip to the Grand Tetons in October.

Thanks for the article.
