A Japanese twin-lens from 1970, a mountain on the ground glass, and twelve frames that will not hurry.
The first thing the Yashica Mat 124G teaches is not exposure. It is posture.
You do not lift the camera to your eye. You open the hood, look down, and the world arrives reversed -- left is right, the mountain sits in a square of glass, and the ground you are standing on is still the ground. In the photograph I keep from that day the finder is a small cinema: snow, a peak, a pale sky, the red grid holding it still. The hood is black plastic gone slightly dull. The straps are leather and blue cord. My hands are under it the way you hold a bowl.
That is the whole method. Look down. Wait. Wind.
A short history of the last Yashica Mat
Yashica built twin-lens reflex cameras in Japan as a serious answer to Rolleiflex -- not a toy copy, a working square. The Mat line ran through the 1960s. The Mat-124 arrived around 1968 with a coupled CdS meter and a pressure plate that would take either 120 or 220 film. In September 1970 they released the Mat-124G. It was the last TLR Yashica made. Production ran until 1986.
The G is not a mystery. It is gold. The meter switch contacts were gold-plated so they would not corrode and lie to you. Most of the bright metal of earlier Mats was painted black. A few parts became plastic. The idea was a camera that looked like the decade it was sold into, and that would keep metering after years of salt air and coat pockets.
What did not change is the glass that matters. The taking lens is a Yashinon 80mm f/3.5, four elements in three groups -- a Tessar-type formula. The viewing lens is a brighter Yashinon 80mm f/2.8 so the hood is usable. The shutter is a Copal-SV leaf: one second to 1/500, plus B, quiet enough that you hear the mountain before you hear the camera. Flash syncs at every speed because the shutter lives in the lens, not in a focal plane. Closest focus is one metre. Aperture runs from f/3.5 to f/32. Bayonet I filters, 30mm. About a kilogram in the hands.
Load 120 and you get twelve 6x6 frames. The crank winds the film and cocks the shutter in one gesture. The hood has a Fresnel screen, a 3x loupe that flips down for critical focus, and a sports finder if you ever need to look through instead of down. The match-needle meter wakes when the hood opens. It wants a 1.3V PX625 cell that is no longer made; a zinc-air stand-in keeps the needles honest. The camera itself does not need a battery to expose film. The meter is a courtesy. The leaf shutter will still fire if the cell is dead.
Kyocera later absorbed Yashica. The 124G outlived the fashion that launched it. That is why so many of us still find one: it was made for sixteen years, and people did not throw them away.
What you actually learn
A TLR is two cameras sharing a box. The top lens is for seeing. The bottom lens is for the film. They move together when you turn the focus knob, but they are not the same hole in the world. At a distance the difference is nothing. Close to a face or a stone, the taking lens is a little lower than the picture in the hood. That error has a name -- parallax -- and the 124G will not correct it for you. You learn to tilt, or to step back, or to accept that the frame on the glass is a letter, not a contract.
The image is also mirrored. Reach left in the finder and the subject moves right. The first roll is clumsy. By the third you stop thinking about it. The square helps. There is no landscape or portrait decision. There is only whether the thing belongs in the middle or against an edge.
Twelve frames is not a limitation. It is the lesson. You do not spray. You meter or you guess. You wind. You wait for the cloud to leave the peak. You remember that 1/500 and f/11 on a bright ridge is a starting point, not a religion. Overcast wants slower glass or a tripod you did not bring. The self-timer is there if you want yourself in the square. The shutter lock is there so the bag does not spend a frame.
I still use the hood more than the loupe. The loupe is for the edge of a ridge or a catchlight. Most of the time the Fresnel is enough: contrast on the screen, the red lines to keep the horizon from sliding. The sports finder stays shut. This camera is not for chasing. It is for standing.
Film choice is part of the learning. The meter ASA scale only goes to 400, which is honest for the era. Slow colour or a 100 black-and-white in good light is where the Yashinon looks like itself -- sharp in the centre, a little softer as you open, the square holding sky and ground with the same weight. Pushing is possible. The camera will not scold you. The negative will.
Why it stays in the bag
There are better-specified cameras. There always were. A late Rolleiflex has a brighter screen and a more expensive name. A modern digital body will show you the mountain before you expose it. None of that is the point of a 124G.
The point is the delay. You look down. The world is small and reversed. You agree with the needle or you ignore it. You press, and the leaf speaks once. Then you crank, and there are eleven left, or six, or one. The photograph in the hood is already gone. What remains is the habit of paying attention.
Yashica finished this design in 1970 and kept making it until the world had moved on. We picked it up anyway. The gold contacts were a small promise: the meter might still be telling the truth decades later. Sometimes it is. Sometimes you meter with your eyes and let the Copal do the quiet work.
The mountain on the glass that day was not a trophy. It was a reminder to stand still long enough to see it the right way up later, on the film, when the hood is closed and the walk is over.
