So I shoot with Canon 1DXs, and while I really enjoy it, for family trips and vacations it is an absolute PIG to carry around.
So I'd like to get a mirrorless camera that i could also use as a back up in a pinch if I had to. I'm looking at either the Fujifilm XT-1 or XT-2, or the Sony A7II. Most likely this camera will be used for family stuff and on vacations so I dont want to spend more, and Ideally i want to keep it small with a single lens or two so I'm not packing around a ton of stuff. Any suggestions? Feel free to add another option if you'd like. As far as the full frame vs apsc, I'm not pulled either way or at least i think i'm not...
First of all, stop thinking of 'mirrorless' so much like a commodity product. One key point of differentiation -- true for mirrorless as it is true for dSLR -- is the question of what size sensor? There are micro 4/3 mirrorless, APS-C mirrorless, and FF mirrorless.
As you go smaller in sensor size, your need for FL diminishes as well, making the lenses 'smaller' only because you don't need as high a FL to achieve the same Angle of View. True for mirrorless just as it is true for dSLR.
So if SIZE is what is driving you to mirrorless compared to your beastly 1Dx body, simply downsize the sensor to maximize any benefit of 'smaller body'...if you buy same FL and same max aperture in FF mirrorless or FF dSLR, there will be little benefit in lens size. In overall kit weight you save only about 10% in weight of mirrorless FF vs. dSLR FF sensor kit. And most of your gain in decreasing size is the body...same FL = 'same size' for all intents and purposes.
To maximize your potential to shrink kit, think of the 4/3 format different choices.
