How often do you replace ISO bearings?

A quick check is when the bearing is steady and the range is decreasing. That’s the moment to make a change.

I can tell we've already been stuck at home too long!

My latest camera has the latest technology in it, so the ISO bearings are not only sealed, but self-cleaning, so they never need servicing. For my other cameras there is an obscure instruction near the back of the operator’s manual on how to service the ISO bearings. By the way, if you have to lube them, make sure to use only 5WT. synthetic camera oil. It comes from used sensors that have been recycled.

Some people go to one of the quick garages to have this done. I bought an ASA wrench and do it myself. I use a stiff dark card to catch the raw material and experience has taught me to use graduated filter to sort out big to small contaminants and of course a speedy light to see under the dark hood. Many times I even put a bracket around the work so that nothing escapes while I'm working on those ISO bearings.

Just take it to the drycleaners and let the pro's do it. I tried it at home in my washing machine but I used too much bleach, as you can see......


Hilarious.

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?

Kaneuter Valve will need replaced also.

See, Linda got it! The more you delete, in camera, the cleaner/noise-free the bearings are. Usually no need for replacement.

The relative wear of those ISO bearings is consistent with the actual AMOUNT of ISO you have been using. IF you frequently use, oh, say, ISO 800-1600, those bearings will wear out much faster. Just stick to the low ISO's and you can delay the ISO cleaning/replacement procedure considerably!

Just don't soak your ISO bearings in dihydrogen monoxide. That stuff is deadly.

I understand that Advance Auto sells ISO photon bearing lube under the trade name 'Blinker Fluid'. It comes in 7, 13 and 69 focal grams.

[quote=krashdragon]Had to google it, but here's the actual grease you want!

Genuine OEM Honda Acura Shin-Etsu Silicone Grease (Single Tube) 08798-9013

You can get it at Costco, but...you have to buy 10!
