Hi, I noticed a local add offering a used Yashica Mat 124 G and went round to see it today. I'm kind of interested to try medium format and understand this camera is good for a starter. Serial number is 7124982. The camera looks to be in great condition, lenses are clear with no sign of fungus or dust. When looking through the viewing lens there is some dust on the mirror. Changing aperture opens and closes the diaphragm. The only problem was the light meter. I know that the MAT 124G meter is not the best but I'd still like to know if it's working. I took along a hearing aid battery in 675 (1,45V) and an adapter. When opening the viewfinder the needle jumps forward when the viewfinder lid is at say 30 degrees and then returns to start position when the lid is fully open. Pointing the camera from shadow to bright light I saw no movement of the light meter needle. Other than opening the lid is there anything else I need to do to activate the light meter ? The camera has not been used in 20 years. I read somewhere that sometimes cameras that had not been used for so long might need some re-adjustment ? I'm keen to avoid any further cost. Seller is not offering any guarantee to I have to take it as is. He's asking 175 Euro. Your comments ,suggestions or other buying tips would be most useful.
