The Hi-Matic E (previously also reviewed by Hamish here) is a Minolta rangefinder with a Rokkor lens. The lens is a 40 mm f/1.7 lens of six elements in four groups. The same specification has been used in other much sought after Minolta rangefinder cameras, like the Hi-Matic 7sii.
The Minolta Hi-Matics have history. John Glenn took a rebranded (and highly modified) Hi-Matic into space. That said, the Hi-Matic E is an odd camera. Caught in an eddy; it has ‘quirks’.
