Cosina Hi-Lite EC II ?

[Hilo]

Hi,
I am looking for pictures of this camera and a little bit of information.

There's also the Cosina Hi-Lite EC (without the II) and I assume the II is not much different. Perhaps all that's different are AE lock and spot metering?

I would like to understand how AE lock and the spot metering work on this camera. Perhaps someone has this camera and can explain? And if you have anything else to say about this camera, all is welcome . . .

Thanks, Michael
