how i fixed focus problem on canon 50mm f:1.8 ef II


my source of information was a youtube video and i decided it's worth trying. first i took several shots of a ruler and i determined that my lens is front focusing. just like the guy in the video! :)

i took apart my lens and i joined by soldering the 2 pins from extreme left (as you are looking to the centre of the mainboard from the edge), just like in the following image.

i reasembled the lens and everything was ok again! :)
(my video on youtube here)

good luck! :)
