A very compact 645, about the size of an Ikonta 521. Neo- Hesper 4 element (Tessar type) 3.5/75, Daiichi Rapid 10 speed shutter, B-500. All function properly and a great, in your pocket, shooter. Glass is clean and clear. I've had Ikonta 521/Tessar and in my experience, the Zenobia results are equal, for a lot less money. As the pics show, a bit of brassing and the covering on the front door is worn thru in a few places. Even so, still a good looking camera. $75, plus ship/PP fees.
