Modern Fujinon lens have electronical parts that may fail due to water damage or other reasons. In most cases it worths pay for repair, but sometimes repair costs are too high and its cheaper to just buy another sample. This Fujinon XF 27mm F2.8 sample was electronically broken, so I've found relatively simple way to convert it into fully manual focus lens.
