My Yashica FX3 metering system are not good as i think. They just stay in green when the shuter speed it's on 30 or below in a sunny day. When i meter with my DSLR and gives me 150-250 SS with the same ISO and apperture.
Can someone help me try to fix this?

Welcome to the forum nergalmcl ... Have you shot any film with the FX-3 yet? That body uses center-weighted metering, and doesn't offer any option to change out of that mode. Your DSLR might be capable of measuring a scene in Matrix mode, or spot, or center-weighted, or in some other averaging mode, and it's possible that they won't ever match since they would be measuring everything differently. That doesn't mean that the FX-3 is reading things correctly, but only that an apple won't ever equal an orange. Do you at least get what appears to be a proper green LED - and - either the expected red plus or minus lights when you intentionally try to under or over expose a shot? If you've already shot and developed a roll of film, and have seen an exposure problem in your results, you'll know for sure there's an issue with the FX-3. If you haven't, you might be able to approximate whether the meter is off with a measurable amount of error, but it will take trying a few things to get close. |

The led goes for over (+) and under (-), but in a Sunny16 rules should gives me correct exposure in something about 1/125~1/250, insted the camera says 1/15~1/30. Welcome to the forum nergalmcl ...

I have not shot anything yet, i'm planing to do something this weekend. And yes i get the red plus and minus when change speeds. |

That's a full 2 stops, and if that ratio is consistent over all the possible value-pairs, then that's more than the usual 30% acceptable error margin for consumer grade cameras. See if the ISO dial is physically out of position. If it is set to it's 2 extreme 'clock' positions, does one end go far past the ISO number, and the other doesn't reach the end? If it's offset, it could be that some part of the dial assembly is out of position and can be reset. If it isn't a physical issue, then it would mean adjusting the circuit resistors - or - if the ratio is always 2 stops off, you might be able to set your ISO value to be 2 stops away from the actual film speed to compensate. |

So from that I assume you mean the FX-3 consistently shows an exposure around two stops more than you DSLR. First, try moving the ISO dial as Lumiworx suggests but not just to see if it has the correct range but also to check if it has any effect on the meter. It could be the ISO dial has been removed and reassembled incorrectly and the dial actually isn't doing anything. If everything appears to be correct then this could be due to deterioration of the sensor. The same sensor is used in several Contax/Yashica cameras and they suffer from (what I think is) mold/fungus getting in the sensor. You can read about it at contax139.blogspot.com/2019/02/does-your-139-over-expose.html (this refers to the 139). I'm not 100% that the same sensor is used in the FX-3 but it looks the same and one I've just pulled out of my drawer definitely shows sign of deterioration. I've seen other cameras with errors up to two stops due to this. But whatever it is, if it's consistent, then you can either just adjust your ISO, as suggested, or re-calibrate the meter. The meter adjustment pot is under the rewind knob. The manual I linked to earlier has details. |
