Canon SPEEDLITE300EZ This is a flash for film cameras. If my memory is correct, it's about 25 years old. I checked the operation, but it didn't work. Three CR123A batteries Panasonic is unopened. Fuji is opened (I don't know if they can be used) They were stored together, so they are probably about 25 years old. (These are not the correct batteries for the flash) I will sell this to someone who understands. If you have any questions, please comment.
