I have three Photomic FTN's. I've used a variety of ways to get a good consistent meter reading without the old mercury batteries from just changing the ASA to Wein Cell batteries and this one adapter has been the best investment to date. It uses standard watch batteries(386) and the voltage regulator inside-not sure if it's a diode/resistor combo or microchip, changes the 1.55 v to an even 1.35v, just what the meter needs. It reads spot on with my luna pro sbc and F2A.
Most happy with this adapter and thought I'd share this link in the even someone has a camera/hand held meter that required a mercury battery. This is a good one.
