Can still add a hotshoe to it if needs be (Both on a dedicated finder, and as an accessory) and it has a sync socket seperate to it.
Metering is TTL. If a bit weird - it uses a beam splitter in the focusing screen to meter.
Meter is needle, match to a ring which shows the aperture. Or stop-down, where the needle must be set into an index.
Flash metering is either not at all - or if you find a dedicated accessory flash and the lens that goes with it.
Shutter goes from 1 to 1/2000 and is fully mechanical.
You can buy addon parts that add power winders and AE features to it. Including lowlight finders that meter out to 30-second exposures.
You can use it to beat a person to death if you need.
