OK so this more venting than seeking advice.
After the crushing disappointment of the LX, I thought a Zorki 4k might sooth the burn, so stupidly I bought one. Again I was joyful as I unwrapped the box that came in the mail. Loaded a roll of film. Later in the evening I decided to waste a few frames to see what the shutter looked like when firing without the lens. To my horror (and then sadness) the curtains only partially opened and closed.
Another day, another lemon.
