Chinon 35F-MA what ?

I found it at a thrift store, payed $6.00 for it, looks almost new, still has the Gold passed seal on the back. Found the manual on line, very little in it that tells me much about the camera. No mention of the lens design 35mm 2,8 best guess a 4 element Tessar type, no information about the top shutter speed, 1/500 was typical for the day. What like is the the meter sensor is inside the filter mount, what I don't like is that takes 46mm filters, I have 48 but no 46. ASA from 25 to 400,non DX codes. The AF is responsive, seems to shoot about 2FPS single shot at a time, power rewind. Interesting looking.

Anyone has one or has more information on the specs

The lens is probably similar to the 4/4 38mm found in Canon's early Autoboys.
