Here's a summary: 1. My Nikon F (about 1969) with a FTn meter head - it takes 2 x 1.35V PX625 (in the meter head). When I had it serviced by a classic Nikon specialist technician recently, he adjusted / calibrated the meter so it could work with modern 1.5V PX625s. 2. My Canon EF (1976) - see above - I use the 1.35V zinc-airs or modern 1.5V PX625's. 3. My Canon F1 (1975) does not have the voltage regulator. The battery just powers the meter as the camera is mechanical. I use the zinc-air 1.35v cells. There are several companies around, like Polar Bear Cameras, selling the LR44 sized 1.35v zinc airs and PX625 adaptors. The zinc-airs give stable output of 1.35v once activated and usually last for a about a year or more and are cheap enough these days (about €12 / £10 for 5 batteries and an adaptor set). Some other companies selling the LR44 / G10 type zinc-airs at 1.4 to 1.45v as 'hearing aid batteries' don't always give a stable output though with 50 year old cameras with old metering circuits, +/- 0.25 volts in unlikely to be a problem but voltage instability is not good for metering accuracy. I have a hand held meter anyway as a check. NB I guess like many of us, I use the cameras as much as I can but with about 20+ 35mm classic cameras in my collection (Canon, Nikon, Contax), the number if films that go through each body might be just 1-2 per year, so I always remove batteries when the cameras are not being used to prevent leakage issues. I have a spreadsheet where I keep a record of when batteries where changed and if in doubt, I recycle the batteries and fit fresh ones. I keep a good stock of batteries in the refrigerator!

So you can use Zinc-air 1.35v substitutes or the ‘modern’ 1.5v silver oxide PX625 clones. Either will work with no issues.Wed, 27 Mar 2024 07:05:33 +0000Do you Want a Ciggy?Olympus M.Zuiko ED 12 on Olympus E-PL2Wed, 27 Mar 2024 07:02:16 +0000Dance 22.jpghttps://www.photo.net/gallery/image/5304974-dance-22jpg/Wed, 27 Mar 2024 05:25:17 +0000At the races 45.JPGhttps://www.photo.net/gallery/image/5304973-at-the-races-45jpg/Wed, 27 Mar 2024 05:17:05 +0000Fashion model 35.jpghttps://www.photo.net/gallery/image/5304972-fashion-model-35jpg/Wed, 27 Mar 2024 05:12:07 +0000Icicleshttps://www.photo.net/gallery/image/5304971-icicles/Wed, 27 Mar 2024 04:32:25 +0000Icicles Studyhttps://www.photo.net/gallery/image/5304970-icicles-study/Beauty of springtime melt in Calgary, CanadaWed, 27 Mar 2024 04:32:22 +0000Wednesday Landscapes, 27 March 2024Wed, 27 Mar 2024 04:12:58 +0000
