So this is what I'm wrestling with now. I know that the current cameras from Fuji and Hasselblad, especially with IBIS, really expand their usability to the point that they've become just as easy to use as full frame or smaller format systems for general photography. I first bought into the Leica system to reduce weight and size for travel. With a workstation laptop and Canon 5D3 + lenses, I was carrying upwards of 45lbs. Trying to make a connecting flight in an airport and running through two terminals, I just got to the plane as they were closing the doors. I was a dripping wet, gasping for air mess. My mistake was holding onto the Canon equipment for years, even though I never used it again. I sold it last year and if course got a fraction of what it cost. I don't want to make the same mistake again. I know if I sell the Leica equipment I'll probably never get back into the system, but I'm beginning to think that might be just fine.
I really enjoy shooting with X2D. So much so that I have used it exclusively for the last five months. It doesn't make sense for every use and I'm trying to figure out where the gap is and the best option to fill it. Even though there is weather sealing on the X2D, I probably wouldn't take it out in anything more than very light rain or snow, and that for limited time.
Hearing why you guys made your choices and how you use your other camera(s) is helpful.
