Introduction
This Samsung NX 50-150 f/2.8 Lens has a fault where if the zoom is in a particular range the electronically controlled focus mechanism fails and the camera displays a message "Error 00" and turns off.
Initially I tried repairing the Flex PCB with some very fine (34AWG) stranded wire, but the required bend radius in the cable was too small and the solder links too fragile.
A replacement Flex PCB was then designed and manufactured. The design was to allow it to be spliced into the stubs of the flex pcb going to the focus motor and sensor, so that the calibrated section of lens didn't need to be opened. This was challenging to solder, but achievable.
Next attempt will be manufacturing a replacement Flex PCB.
The lens now focuses correctly and does not show the "Error 00" message. Alignment of the lens does not seem to have been affected.
