A camera lens is a very complex system and unreasonable interference with its device can irrevocably destroy the mechanism. But, as you know, there are very few authorized services for the repair of photographic equipment, sometimes they cannot be found even in large cities, not to mention smaller settlements, and an attempt to repair the lens on our own becomes the last opportunity to revive an untimely deceased pet.
It is necessary
- - Phillips hour screwdriver
- - several sheets of blank paper
- - containers for folding screws
- - lens wipers
- - rubber bulb for blowing off dust
- - the lens itself
Instructions
Step 1
Take a good look at the disassembled lens. Let's say you decided to disassemble the Nikkor 18-55. All manipulations should be carried out over white paper laid on a flat surface in order to avoid the loss of small parts and details. Along the perimeter of the mount you will see three black screws, carefully unscrew them. Turn the lens sideways, with the contacts facing you, unscrew the two screws that secure the contact plate. Even before disassembling, you will notice that the screws are different from each other, so it is better to put them in different containers and note which screws were unscrewed from where. Remove the top plastic ring adjacent to the contact plate.
Step 2
The next step is to unscrew the three small black bolts located on the same annular surface to which the contact plate was attached. Remove the ring with the diaphragm control plate. Using very gentle movements, unscrew the contact from the removed ring. Next, you can see the 4 white bolts that attach the rails inside your lens. Unscrew them. Pull out the rails and lightly pull the inside of the lens out of the barrel. Now you can proceed with what you disassembled the actual lens. For example, cleaning the lenses from dust.
Step 3
Lens assembly is performed in the reverse order of disassembly. When inserting the inside of the lens backwards, note that there is only one way to insert it, so that the protrusion on it fits exactly into the slot provided for this. Replace the guides, screw them on. Gently screw the contact back onto the old place. Reinsert all the rings you removed, pull the diaphragm rod slightly to make sure everything is in place. Screw all the screws back into place. If you perform all the actions with the utmost care and accuracy, then nothing terrible should happen to your lens. But remember, you and only you are responsible for all your actions, so carefully weigh the need for this action before proceeding with the disassembly.
