Yashica TL Electro X

The defining trait of the TL Electro X lives inside the finder: two arrows, one pointing up and one pointing down, lit by the meter. Most M42 SLRs of the late sixties handed you one match needle and left it there. Yashica gave you arrows that you switch off. Turn the aperture ring or the shutter dial, and you adjust until both lamps die. Overexposed, the top arrow glows. Underexposed, the bottom one does. Both dark, you are at the reading. In dim light, where a thin needle vanishes against a murky ground glass, those arrows stay readable, which is more than the competition could say.

Underneath the gadget it is a straightforward heavy SLR with a screw mount. The body is dense, all metal, the kind of weight that makes a strap dig in after a day. The shutter is a focal-plane cloth design running from a full second up to about 1/1000, with flash sync at 1/60. It is not silent. You get a solid mechanical clack and a touch of mirror return, a sound with no pretense to it. Focusing runs through a microprism collar on a reasonably bright screen, and the M42 thread means you can mount four decades of Takumars, Yashinons, and assorted budget glass that piles up in every junk bin.

The meter is the interesting compromise. The CdS cell needs a battery, and the metering electronics drive those arrow lamps, so the camera leans on its cell in a way a fully mechanical Spotmatic does not. The shutter itself fires without power, but the whole reason to carry this body is the metering display, and a dead battery leaves you with a manual SLR and no read at all. The original cells were mercury, long gone, so most working examples run on a modern substitute and a small voltage correction in your head.

People mostly find this one cheap and stay for the arrows. It sits well below a Spotmatic or a Nikkormat in price and reputation, partly because the name says Yashica and partly because collectors chase the screw-mount Pentaxes first. That is exactly why it is a bargain. The glass is interchangeable with the entire M42 universe, the build is heavy and durable, and the metering display is more intuitive than anything its rivals offered. The honest weakness, beyond battery dependence, is the aging electronics. When the meter lamps die or the cell drifts, you are into a repair that nobody wants to quote, and parts are not raining down.

That dependence is why the app matters here. When the arrows have gone dark for good, or you simply do not trust a fifty-year-old CdS reading off a backlit street, take an incident or spot reading with Zone Light Meter and set the lens and shutter from that. The arrows were a clever meter for their day. Once they quit, you carry the app instead, and the body keeps going as the solid M42 shooter it always was underneath.
