Minolta light meter reset
Am selling a few of my previous boss’ old photography equipment – including Canon film SLRs. Started with bits that didn’t need a clean including a Minolta IV F Auto meter – a light meter. When photographing it I thought I’d give it a quick test and found out that it was way off! My light meter was giving f8 (1/250 ISO 100) while the Minolta gave f22! There is a little dial to adjust within the battery compartment – but this didn’t give enough variation to reach f8. I did a few searches to find out how much it would cost to calibrate it when I came across this video.
It sounds strange – but it actually works!
I first tried it with a piece of card and didn’t run – and it didn’t work. Then tried an actual US dollar bill (I happened to have one) and did the rubbing thing – and it worked!
Is so strange – can’t imagine this is a true calibration – at best guess it either cleans the contacts or somehow removes a charge in the system. Not sure how a dollar bill/rubbing would have changed things.
But it’s so strange – thought I’d post it.
Here’s the lightmeter on eBay if you fancy one. Auction ends 29th April.
