How often do you replace ISO bearings?
Apr 1, 2020 09:14:45 #
I was thinking about checking into having my ISO bearings replaced or at least checked. Does anyone know how many photons they can absorb before they need service? Can I just have them cleaned, or do I have to get new ones? Or is it the noise that primarily clogs them up?
I've always read that ISO has a bearing on noise, so it made me wonder even where these bearings are located? I've always assumed it was similar to dual pixel technology, where it is embedded in the sensor array. I know it has to do with the deep well capacity of the photosites, so the bearings must be at the bottom of the well? Do full frame cameras need the bearings changed less often because they have greater well capacity?

In order to check for bearing damage you will need an Argyle Pump. A regular Plaid Pump or the hard to find Paisley Pump will not do the job. Hope this helps.

Just don't forget to change your blinker fluid at the same time. Why disassemble the camera twice?

I found that when replacing the ISO bearings, it's better to stick to OEM parts and never with 3rd party. The cost for the replacement is substantial no matter which way you go. If you stick with higher ISOs, you'll find that replacement is often never needed IMHO.

It doesn't matter if it's FF or a crop sensor because the ISO is on a totally different location of the mother board. I clean mine about every 100,000 images, which is Nikon's recommendation. You can do this yourself if you wish, but you have to take the bottom of the camera off, where the battery is. I don't know anything about Sony, Canon, or the other manufacturers, but that's where it is on a Nikon. After removing the cover, you will see a tiny cylinder (resembles an old transistor) and you take a swab soaked in alcohol and gently wipe across the ISO sensor. This will remove the residual noise.

I usually change mine myself. I have a B&L microscope that I use to help see to the bottom of the photosites. Sometimes getting the light to the bottom of the photosites so you can see is the hardest thing. As far as where I purchase my ISO bearings. I've tried eBay and Amazon both. Neither seemed to carry a quality product. I usually take the old one to a local toolmaker and have him duplicate what I need. Best of luck and if you need a microscope both AO and Band L can be found on eBay relatively inexpensive.

I have a service connected hearing disability so I've never heard the noise. I knew I was missing something so when I cleaned my ISO bearings (on the Sides of March schedule) I installed a 3 amp vortex generator under my flip screen. Now when I'm listening for noise I open the flip screen I have a cool tropical breeze across my face.

How many photons before any problems ? On good authority 50 grams is the limit. Your shutter will die at least 3 or 4 times first. Don’t worry be happy;-)

You will need to go outside and find a good landmark, so you can get your bearings.
