What better things to do during election day than fixing things up.

List of things to fix:

  1. Canon EF-S 18-55mm 3.6-5.6 IS stock lens – problem: auto focus kaput

  2. Quantaray LD 70-300mm – problem: auto focus kaput.

Let’s start off with quantaray.

This one seems to have gear problem since when it tries to drive the focus you could only hear the motor whirl freely.

The cause of the problem was that the gear’s upper tooth on the right were all strip, I don’t know what cause this, since the lens is not mine and was borrowed from my uncle.

A workaround is to swap the gears position since both are identical and the second gear position seems to not use those tooth anyway.

As for the canon lens the Focus FPC has split into two and needs replacement.
