Rings on Mamiya 135 EE

[nichk]

Dear all I am new to RFF! So hello to everyone!

Also I am a newbie on RangeFinder!

Yesterday I bought a 2nd hand Mamiya 135 EE.

I found there are several rings on the lens and I am not really sure about the function of the innermost ring.

Can anybody helps me on that?

Thanks so much!!!



Below are some images of the rings:

I am not sure the function of the ring with the red " AUTO 。。 flash 。。 "

There's an "AUTO" and a symbol for a flash and four plain dots. Seems possible that this is a program kind of camera which sets both shutter speed and aperture. If another member has one, you will soon know what the dots mean. Evidently you got no manual or instructions with the camera.

Welcome to RFF, nichk.

[edit - addition] Your camera is of the program kind. See bottom of herron.50megs.com. Manuals are available (Google turned up two sources), but the cost is 15 UK pounds.
