Introduction
This guide shows how to disassemble a complicated (but cheap) SLR lens, and hopefully reassemble it in working order. Please note that this is a fiddly and complicated procedure; if you value your lens and definitely need it to work, service it. I purchased an "untested" camera from eBay that had obviously been drop tested.
What you need
-
-
First, remove the two screws in the barrel of the lens with a philips 0 screwdriver
-
-
-
Gently manipulate and remove the AF/M focus switch - it is held in by four easily breakable brittle plastic clips.
-
Watch out for the autofocus mechanism and control wires. They are very delicate.
-
It's a good idea to switch the lens to manual at this point - adjusting the focus can help when removing the autofocus motor

-
That's as far as I went - the zoom was no longer jammed, and reassembly was the best option here! Reassembly is the reverse of disassembly
-
The aperture unit/rear element is slightly tricky to put back. Make sure you align it correctly (lens nearly at 35 mm, so that the screw holes are high up).
-
Remember to blow dust out of the lens if you see any as you are reassembling it. Do not use anything liquid to clean the inside of the lens unless you know what you are doing.

Complete disassembly and some super glue fixed my lens, but not everyone will be so lucky.

Is there any way to disassemble the lens from the front to clean front elements?
