Wow, it's been awhile since I've posted on DPreview - been so busy with my other passion - esoteric audio.
I've often chimed in on different forums here (my being a multi system slut) that the one system that has me firmly entrenched in its design philosophies, is Fuji. Yes, I shoot with EOS M gear and yes, I've also talked about how much fun it is to shoot with M gear.
But there is something about the Fuji line that has intrigued me for years. Some 7-8 years ago (after being firmly entrenched in regular Canon, Nikon, and Micro 4/3 cameras), I took a chance and purchased the (then) X-E1 with 18-55 F2.8-4 IS lens. I was totally prepared not to like it (don't know why - but I was). However, when it arrived, I became mesmerized with features such as build quality, ergonomics, the retro-look, and most of all...IQ qualities. I soon became hooked on Fuji thereafter.
For me (and that's all I can talk about really), the Fuji cameras do the following:
1. Give me a woody in general while using it (and that's saying something at my age)...
2. Have superb high ISO capabilities (read very clean here). In fact, whenever there are photo shoots whereby I must shoot low light scenes, I immediately reach for my Fuji cameras.
3. Color tonality - I enjoy the way colors are rendered, in particular skin tones.
4. Fuji's philosophy on keep up with timely firmware updates and in some cases, they will release FW updates for cameras that have been out of date for almost 5-6 years - now go figure.
5. The largest selection of APS-C lenses on the market - this is a biggie (for me, that is).
So IMO, you cannot go wrong with trying out and subsequently jumping into the Fuji system. You will find many other multi-brand users also using Fuji - that's the fun of it all.
Good luck in whatever you do.
