The X100T would be easier to rule in or out, as it has a fixed lens that will be adequate or not. By itself it is roughly equivalent to 35mm f/3. There are a couple of lens modifier accessories, which widen it to 28mm equivalent, or lengthen it to 50mm equiv., both I believe without further changing the aperture. Also having the original X100 myself, do note the optical viewfinder part of it works differently than on a DSLR, and I like it a lot less than I thought I would once I got it. I find it usable for framing only and personally I find it unnerving not to be able to see focus change in the presented image like you would on DSLR. So if you use AF and it is off for any reason, you'll be unaware of it until you review the taken images. You can of course work around this by using the EVF mode, but then you negated a major point of this model series.

 

If that is not adequate, then it is as Brightcolours says, what lenses and apertures do you normally work in? From there you can figure out how best Fuji or other system meets that.
