I believe these items are junk. The YASHICA Half 17 has some scratches and the internal sponge has deteriorated. The auto function is broken, but the shutter can be pressed! The selenium photocell is very old, so its functionality is unknown. The case is falling apart. The RICOH SE2 also has scratches, and the selenium photocell may be bad. The case is relatively clean for its age. The RICOH flash turns on, but it didn't react when attached to the SE2, so it's unknown if it's broken. It has a case. The condition of the selenium photocell for the RICOH EF is also unknown. The internal sponge has also deteriorated! I think the auto function is also broken on this one! I had them checked at Camera no Kitamura, and they said the shutters on all of them can be pressed and the film winding is normal. They said it's possible they can take pictures, but it's unknown because I haven't actually put film in and taken pictures. I accidentally turned on the timer switch on the RICOH EF, so it won't reset until film is loaded and the shutter is pressed. The flash did work. There are a total of four items. Since various things are unknown, I am selling these as junk items. Please understand that these are over 30 years old. I am not familiar with cameras, so please understand that my descriptions may be incorrect. No claims, no returns.
