拆鏡之後發現九片光圈葉片完全黏死在一起幾乎無法分開，這也是造成光圈環無法轉動的主因
全鏡拆解依照鏡片、光圈葉片、對焦環、光圈環、鏡筒 等各部份分別清潔與重新潤滑。耗時費工過程，最終將它完整修復！
***這支鏡頭縮光圈時是呈現三角形的形狀，修復之後忘了拍照片～
This Zeiss Planar 85mm f/1.4 B-Speed series cine lens came to my repairing shop in a very bad condition. The focusing ring was very tight, aperture ring was unable to rotate and all the lens elements were dirty and hazy, so full disassembling for a completely restoration is necessary.
After took apart the lens, I found the 9 iris blades were completely stuck together with dried grease that lead the aperture ring unworkable.
The restoration work was divided into several parts: thoroughly cleaning all the lens elements, taking apart and cleaning the iris blades, cleaning and re-greasing the focusing helicoids and aperture ring, cleaning all the lens tubes externally and internally. Each part took a lot of time, and finally the work was successfully and completely completed.

*** The 9 iris blades of this lens are divided into 3 groups, when stopped down the diaphragm produces triangular shape. I forgot to take pictures after the restoration work.
