I don't think you could fit the Tenba in this, but for that size (just a camera and a few accessories; with Fuji/mirrorless, an extra lens or two as well), and matching the "man purse" description, I really like my Domke F-5XB. It's on clearance right now at Best Buy if you like green (I have the F-803 in that color combo and it's pretty sharp looking). My F-5XB is the waxwear brown, though.

Usually I go in with the body/lens around my neck on a strap. I also have a smaller bag (https://www.amazon.com/Domke-F-5XB-Shoulder-Belt-Ruggedwear/dp/B002BH3XXQ/ref=sr_1_1_sspa) that I'll usually bring in that has a second lens.
Think Tank Mirrorless Mover seems pretty small? If that's still too big the Domke F-5XB is pretty damn small but doesn't fit an iPad. Something larger than both is the S-Zone Messanger bag.
