The Chinon CE Memotron was not made by one of the big well known manufacturers like Canon, Fujifilm, Nikon or Leica and can be therefore purchased these days for very small money.
The Chinon CE Memotron
What makes the Chinon CE Memotron special, is the fact that it is one of the rare SLR cameras which works with almost every M42 SLR automatic lens in aperture priority mode. Every lens which has the small metal pin at the back for the automatic aperture will work with the camera in automatic (aperture priority) mode. With the shutter release pressed down half way, the meter reading can be stored/locked (that's where the name memotron comes from) by pushing another button on the side of where the lens is mounted. Due to the mechanics involved, the shutter release has a quite long travel way which might be the only drawback of the camera.
Very well made
The camera is very well made with a brass top plate underneath the black paint. If you hold the camera in your hand, you can feel the quality since it is more on the heavy side.






The film advance lever has a very nice gear transmission ratio which leads to a short and distinct travel way.

Double exposure lever

Double exposure lever

Focusing with the viewfinder is easy due to the possibility to focus with open aperture when using automatic lenses.
All the nice M42 lenses
As much as I like the Bessaflex because of its tiny size and bright viewfinder, it has a big issue with several lenses where the rear element is hitting the mirror. The quinone has not such problems. The camera just accepts each and every M42 lens and works flawlessly with them. ...and there are some fantastic M42 SLR lenses being made!
Currently I use the following lenses with the Chinon aka Revueflex 5000EE aka Porst Reflex M-CE:
- Pentax Super Takumar 50/1.4
- Carl Zeiss Jena Flektogon 35/2.4
- Carl Zeiss Jena Sonnar 135/3.5 MC
pros
- Works with all M42 lenses
- Aperture Priority Mode with almost all automatic M42 lenses
- Meter lock switch
- Fantastic solid built quality (brass)
- Double exposure button
- Nice short defined film advance
- Up to 1/2000 shutter speed
- Very reasonably priced on the second hand market
cons
- Long shutter release travel way
- Dependent on battery
