LEICA SUMMICRON-M 35mm f/2.0 ASPH. 11611 Millennium Black Paint 黑漆版 鏡片清潔 Cleaning lens elements

這支 LEICA SUMMICRON-M 35mm f/2.0 ASPH. 11611 Millennium Black Paint 鏡片有髒污薄霧，全鏡片拆解清潔。 非球面鏡片在拆解清潔完成後，組裝時 需要特殊的三邊校正，保持光軸不偏移，確保成像品質。

This LEICA SUMMICRON-M 35mm f/2.0 ASPH. 11611 Millennium Black Paint had slight fog and dusts internally, so I made a full lens elements cleaning. 

After cleaning, during the reassembling procedure, the aspherical element needs additional trilateral calibration (three point adjustment) to keep the optical axis without biases and ensure the optical performance is the same as its original condition. 

Leica Leitz Summicron 35mm f/2.0 v.1 八枚玉 8e 鏡片霧化變質拋光 Polishing to the hazy/deteriorated lens element surface

這支Leica Leitz Summicron 35mm f/2.0 v.1 八枚玉 的鏡片有嚴重的變質問題，鏡片看起來完全是霧的，很難看透。這支鏡頭有兩個鏡片表面有嚴重變質的問題，在這樣的狀態下拍照，成像完全是霧矇矇的，是一支沒辦法再使用的鏡頭。 為了要讓它能夠再拍出乾淨通透且清晰的照片，拋光是唯一的方法。精準的拋光能夠讓鏡頭重生，成像也能保持原始狀態

最後的三組拋光前後的測試照，可以清楚看到處理前後的成像表現有極大的差異。

This Leica Leitz Summicron 35mm f/2.0 v.1 8-element had serious problem in elements surface deterioration. It looked completely foggy and was difficult to see through. There were two element's surface had serious deterioration as you can see in the following images. When taking pictures in this state, the image would be completely foggy, and no one want to use it again in such bad condition. 

In order for it to take clean, transparent and clear images again, polishing is the only way. Precise polishing can revive the lens and keep the image in its original state. 

In the last three sets of test photos before and after polishing, you can see the huge differences in imaging performance before and after treatment.

Carl Zeiss Planar B-Speed 85mm f/1.4 全鏡清潔修復保養 Full lens cleaning and restoration

這支蔡司 Zeiss Planar 85mm f/1.4 B-Speed系列的電影鏡頭 來到我工作室的鏡況很糟糕，對焦環很緊、光圈環無法轉動、鏡片有嚴重的髒污，理所當然就是全鏡拆解清潔重新潤滑

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.
