Another Minox ex owner here. My EL worked for all of about 2 minutes, then the meter stopped working and the aperture would only stop down to f8 no matter how far you turned it. Thank goodness I had bought it at a camera store and not from an auction site, so I made an easy return. They were going to let me know if it had been repaired by their staff but never got back. The concept is fine, but the actual camera, that seems to be the problem. Sure was a lot of fun to play with though.
The samples from the Minox cameras look great from what I see online. There's been a lot of emulation, if you will, by other camera makers over the years. More than a few of them made Minox clones, especially the Soviets (many with non light-proof body AND aperture blades it seems). Now that's a bad concept....a Soviet knockoff of a camera that never worked right in the first place.
