Konica EE-Matic Deluxe F

The Konica EE-Matic Deluxe F is a fully automatic rangefinder with a flashbulb socket on top, that automatically opens when switching from "A" to "B" mode. The viewfinder is large and bright, and has fixed framelines with parallax marks. There's no indication of speed or f-stop inside it, but a small reflected red icon depicting a hand lights up when low light might cause the camera shake to blur the picture. It uses a single PX625 battery.
