Yashica's black Electro 35 GTN — fixed-lens 35mm rangefinder, f/1.7 lens, electronic shutter, 1973.
The Yashica Electro 35 GTN, from 1973, was the black-finished counterpart to the chrome GSN in the Electro 35 line of fixed-lens 35mm rangefinders. It shares the same body and electronics as the GSN and differs mainly in finish, and both are among the most sought-after of the widely produced Electro 35 series.
This is a 35mm coupled-rangefinder camera with a fixed 45mm f/1.7 Color-Yashinon lens and an electronically-timed leaf shutter. It uses aperture-priority automatic exposure, with the meter selecting a stepless shutter speed and finder lamps warning of over- and under-exposure, plus a hot shoe for flash. The electronic shutter needs a battery to fire at correct speeds; the original was a mercury cell.
The GTN suits available-light and street shooting, where its bright lens and quiet leaf shutter are advantages, and the black finish appeals to users who prefer a less reflective body. It is easy to use for travel and everyday photography via the coupled rangefinder, though it is heavy and offers automatic exposure only.
When assessing one, look for the pad-of-death (POD) fault common to Electro bodies, which affects shutter timing and advance. Test the meter, exposure lamps and battery check, inspect the lens for haze and fungus, and check rangefinder patch contrast and alignment. Replace perished light seals, and plan to substitute the obsolete mercury battery with a modern voltage-appropriate cell.
