I've been using an ONA Prince Street for a couple of months now and I'm crazy about it.
XT-1 or XE-2 with 18-55 or 18-135, also 35 f1.4, 55-200 lenses; Nissin i-40 flash and lots of miscellaneous stuff.
Good looking bag, very well made, extremely well padded, fairly inconspicuous and very comfortable to wear/carry.
I have probably dozens of bags sitting around, in corners, in closets, in the basement, etc, and I haven't found anything that fits my small Fuji mirrorless systems as well as does the Ona Prince Street.
