Superfast (for a fixed lens RF) 45mm f/1.4. That's a lot of glass and this was the late 60s so it's not a compact camera.
Full manual mode, battery only powers the meter.
Yashica build quality, that is to say: fine but won't win any awards for being particularly refined or smooth.
Awkward but lovable styling.
All exposure controls set by rings on the lens barrel
