After moving to Fuji X system I extensively used large number of Trans-X bodies and XF lens. Most of them perform excellent optically and very good mechanically. I think Fuji is doing great job designing and supporting gear.
The only thing is bothering me all the time - if the electronics is dead lens typically becomes fully unusable. There are numerous third party or adapted fully manual lens that solve that concern. But what if I want to keep using my favorite Fuji optics mechanically? I've performed numerous attempts and discovered potential of converting XF 35mm F1.4 and XF 27mm F2.8, and recently found highly satisfying result of adapting Fujinon XF 27mm F2.8 that requires relatively low effort.
Here's resulting article explaining what can you do with electronically dead Fujinon XF 27mm F2.8 lens to bring it back to life in much more compact frame of Industar 50-2.
Alternatively you can also use adapted Fuji XF 27mm F2.8 lens on other APS-C cameras like Sony or Canon.
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.
