Well done! And what a neat and accessible design by Sekonic! I have a new L-208 Twinmate in the mail to me and as I'm used to work on my gear I will calibrate it myself if needed when it arrives. I also have several other meters available for reference.
I have just purchased from ebay seller and found that it is under exposing for reflected light by about a stop. I was planning to return it but now after watching your video know that I can adjust it easily fix it. Thank you so much for the info.
Thank you so very much. This meter had been driving me crazy for a very long time. I thought that there was something wrong with it but how could it be off from the factory?? Well guess what.. it was! Kudos to you!! It does raise the question as to why does this meter not have a null point adjustment?
The reason you have to press twice is actually because you're measuring incorrectly. You need to press and hold the button for at least 1 second (a quick press would just be a fraction of this). In your case, the first press just gets it close to the reading and the second one gets it on. The manual mentions this, but it's easy to overlook. Calibration worked great! Compared it to my L-308X and my E-M5 camera and all three agree now. The Twinmate is a good little meter, especially for quick lighting confirmation.
That's really interesting that it needed to press for a whole second for reading... I'll test it out... Some older meters doesn't even require such a long metering time.
Just found you this evening as I have just bought an OM1 and the self timer lever is missing, so I thought I would watch your video as I have several Olympus old and new, as well as lots of other cameras, however this took me on to a couple more of your videos and really impressed especially with the light meter as I have the same as your old one and was looking for another. Excellent really helpful thank you so much. Regards DG New Forest U.K. I’ve subscribed and ticked. 📷🎥
Hi, thanks a lot for your tutorial...but I've a question...why I've two different read from first to second measurement?I've noticed that the second remains always the same...so I've calibrated according the second read out.
I also bought this light meter, in incident light the reading is precise, in reflected light, underexposed by one stop ... I have here other 2 professional light meters and many cameras as a comparison. But if I corrected it, I expose it to correctly expose it in reflected light then I would make it wrong in incident light ... And I also bought 2 on Amazon to compare them ...
Incident meter valve is affected by the white dome, if dome is deteriorating then it would get darker when dome is on top for incident metering. That explains why when you remove dome for reflected metering the meter goes underexposed. Also the color of background used for reflected metering needs to be 18% gray, other color will cause meter to be confused when metering and cause over/under exposure. Many things may cause unreliable reflected metering value that’s why incident metering is most accurate, once properly calibrated.
Does the meter agree with the others at lower and higher light levels also? (Analog movements usually have had separate adjustment points for low and high readings.)
