<p>After reading for some time on the internet over the past nights i decded this morning to do the conversion myself.<br>
I have done the conversion on the older but still brand new 85 PC version, not the PC-E.<br>
The flex wires were each bundled with a tiny piece of sticky black tape. After having removed the tape very carefully by cutting the tape on the side of the flex wire, i turned the square assembly 90 degrees, and make sure that the locking knobs for tilt and shift come on the same side of the lens assembly. Carefull assemble the unit again, and before screwing it back together test if every thing moves easy and fluent.<br>
Also test the button that closes the diafragm several times before screwing back the final assembly together. <br>
If you make the rotation in the wrong direction, the flexcable will get stuck in mechanical parts. This is easy recognizeable when the locking knobs are on opposite sites of the lens after assembly.<br>
Be sure to have absolutely the correct size of screw driver before you start.<br>
It took me less than 15 minutes to complete the job .... <br>
Only try this when you are an experienced person with affinity for small mechanics and be very very careful with the flex cables.<br>
Last line : Do not do this at home, you could ruin a perfect and beautiful expensive lens.<br>
I also do own the 85 PC-E wich will not be converted, but now can use either lens for the specific job.<br>
In case of questions you can send me a personal message.</p>
