Fundamentals: Grease and Lubrication (2/3)

We had a lengthy commentary on screws and drivers on the previous post and the next important subject to consider is lubrication. If you have read any of Nikon’s repair manuals you will see that Nikon uses different types of lubricants on different parts of their lenses and cameras. While this is the best practice in camera manufacturing, it is not practical for DIY lens restoration for a lot of reasons, some of which are:

  • It is expensive to keep an inventory of various lubricants.
  • It is not cost effective if you are just fixing your own stuff.
  • You may accidentally mix lubricants.

With the above considerations outlined, we will now start discussing about the most important lubricant in manual focus lenses and how to properly replace them.

Prep:

Before applying any fresh grease to your helicoids you will definitely need to clean the helicoids first and remove the old, dirty or dried grease.
