Sears 2000ES instruction manual

This seems to be a thread mount AUTO camera.  Seems to be similar to the alpha SI2000 ?

Note the AUTO setting on the shutter and 1/2000

A few cameras  ingeniously were able to use ALL 42mm lenses for full aperture priority exposure. They did it by taking the exposure reading  just after the lens stopped down, and just before the shutter opened.  This rather short list is useful if you are searching for a convenient AE body for your thread mount lenses.  The ones  I know about are:

• Chinon CE Memotron, advanced silicon metering system, 2-1/2000th second shutter, aka GAF L-ES, Sears 2000 ES.
• Chinon CE2 Memotron,  advanced silicon metering system, 1-1/2000th second shutter, aka GAF L-ES2, Argus CR3E
• Chinon CE-3 Memotron, all of the above in a compact body.

The Chinons offered advanced features such as motor drive, radio control, intervolmeter, and a very advanced Data Back.

• Cosina Hi-Lite EC  4-1/2000th, silicon metering, aka Argus / Cosina EC 2000
• Cosina Hi Lite ECII, AE hold added, spot and averaging meter, aka Vivitar 650 SLX

• Yashica AX,  CDS metering
