Works perfectly with Canon F-1n
The through-the-lens (TTL) light meter of my Canon F-1 (2nd iteration) is meant to use a mercury battery, which you can't buy anymore. These WeinCell batteries are the perfect replacement. They output the correct/expected voltage, so the metering is accurate - I've used the TTL meter for many conditions (indoor, outdoor, sunny, shady) and it has given great results across the board.<br /><br />Without these batteries, I couldn't use my vintage camera in the way I like to use it. I'm very happy for this product!
