Hey peoples. I recently got my hands on an old Vivitar 2800 Auto Thyristor flash and a Nikkor 50mm 1.4 AI Lens, and I've taken a few photos with it. I was eating peaches, and I thought, "hey why not?", and came up with these photos. The third photo is a picture of a keychain with my name written on it in Taiwanese. A Taiwanese friend recently came back from her trip to Taiwan and brought them ;D Version 1: Version 2: Similar: I do realise old flashes such as the Vivitar 2800 I used for these shots have high voltage peaks. According to the manual, my Nikon can withstand up to 250volts before it gets fried. I looked online for the voltage rating for the Vivitar flash and I've been getting different measurements ranging from 10 - 180volts. So with this huge variance, you might understand why I'm a bit uneasy at this point about continuing to use this flash unit. I understand its the PEAK voltage that really matters when the flash fires. Does anyone have any ideas?
