Hello, everybody! I am in the process of fixing the pipeline of our studio at the moment. I am spending many hours evaluating and creating new tools for our artists and throwing away what the previous guy did. He basically made everything too-complicated and now he can’t fix it himself and so he had to quit! Making something more complicated so that only you know how to fix it can backfire, too. Instead of giving him job security, it made things more difficult for him and everybody else so the company is losing millions of yen in wasted time and missed-schedules. Being a tinker, I am used to seeing what others did and how and where things can be improved or fixed. Today, I’m going to show you a little mod that you can do to save yourself some money.
Introduction:
Many useful photography gadgets like light meters, cameras, etc that were made several decades ago all share something in common that limits their use today – the use of an old battery type that has a different size, voltage and chemistry to mainstream batteries that you can buy today. These are the old mercury-type cells that went out-of-fashion around the late 1980s. It was a very good battery type because the power drop-off is steep so this will allow it to function near its nominal voltage for longer until it exhausts itself. Newer ones that use different chemistry has a smoother fall-off curve so they’ll emit lower and lower voltage gradually until they die. This leads to erratic operation like inaccurate and intermitent operation. The call for greener batteries resulted in the end for this because it has a scary-sounding name and so these batteries are now scarce. Sure, you can buy a few alternatives like the Wein cell but they’re not cheap at all and they usually die within a few months whether you use it or not. Hearing aid batteries share similar dimensions but the voltage is different and they can be hard-to-obtain in an emergency. The best way I know of is use the common and cheap 1.5v batteries and modify your gadget so they’ll work with them with as little fuss as possible. This is a popular mod that any people do, I am sure that you have seen or heard this done somewhere, I personally learned about it some time ago in the 1990s when these batteries are beginning to become scarce.
You will have to open your gadget just like what you see in this picture. It looks scary but it’s one of the easiest things you can do if you’re an intermediate-level repairer. This is an old Sekonic Apex light meter, it’s one of my favorite meters because it’s easy-to-use and it is still reasonably-accurate in everything but poor lighting conditions where light ratios and other things may affect its performance. The only thing that I hate about it is it uses the older 625/MR-9 mercury-cells. Somebody stole my trusty Sekonic L-308 that I’ve been using for many years and so I had to bring this old meter back from retirement.
