Tested and working: Olympus Pen EE Late Model EL Type (Stock No. O10)

This camera is a half-frame AE camera, a later model of the Olympus Pen EE, which was first released in August 1961 with a fixed shutter speed of 1/60 second. In May 1962, the shutter speed was improved to two speeds: 1/30 and 1/250 second. Further improvements were made in 1966 with the addition of a slit to the take-up spool, and it was then sold as the Olympus Pen EE-EL (Easy Loading).

The camera functions well.

There is a slight dent near the strap lug on the right side of the body due to a drop.
There are traces of touch-up paint after removing minor rust on the top of the back plate.
The light seal on the body has been replaced, but it's a DIY job.

The light meter functions generally well for a 60-year-old camera.
The red flag also works without issue.

The manual aperture control for flash photography works as indicated by the orange markings on the aperture ring.

The lens is generally clear.
Fine dust can be seen in the viewfinder.

The filter is a Kenko Skylight (1B) 43.5mm, with signs of use commensurate with its age, but still usable.

The external flash gun holder is an Olympus genuine product.

The strobe is a National PE2002, with a guide number of 20 at ASA 100.
The anti-slip spring between the shoe and the strobe is strong, requiring considerable force to attach and detach.
The strobe case shows considerable signs of use.

The instruction manual is a common one for the Pen EE and EES, printed in 1963, so the film loading image is from before the EL type, but there is no particular problem.

The lens cap is an Olympus genuine product, but not specifically for the Pen.
The camera case and mini strap are Olympus genuine Pen-specific products.
