Updated! Homemade PX625/PX13 Replacement Adapter!
I have completely erased the previous tutorial due to my new and VERY simple, yet effective method. First of all, I’d like to say that, people who tell you to avoid any camera equipment that uses PX625 are stupid.
The 675 Zinc Air for hearing aids are the size of the regular SR44 / LR44 button battery, Its not the same physical size as the PX625. We don’t need to make a washer, or any plastic adapter, instead. go to your kitchen and grab a bread tie. I’ll show you how I fit that in the 35RC.
Now, If you don’t have access to the 675 and still want to use SR44 or LR44. I will use LR44 because its 1.5V, the SR44 is 1.55V. Just make sure you know that your meter will be almost one stop off (but who really cares, or set the ISO to compensate). In a camera or meter that takes 2 PX625, such as my gossen lunar pro, the 2 LR44 will produce 1 stop difference than the PX625.
I just saved you a lot of money. Now go shoot.
