BelOMO AGAT 18K
I bought BelOMO AGAT 18K when I was looking for a portable, manual camera with a decent glass lens. AGAT 18K's small form factor made it look like a try, except that it comes with an Industar-104 f/2.8 glass lens and support ISO up to 1600, making it a very versatile camera one can keep in the pocket all the time.
