Kinoptik Focale Fulgior 50mm f/1.3 前後鏡片拋光 Polishing the front and rear lens elements

這支 Kinoptik Focale Fulgior 50mm f/1.3 前、後鏡片的外側面的狀況相當不好，不知是因為不當清潔擦拭或是鏡片本身變質造成，實際拍攝的成像非常不好
解決這問題唯一的方法就是"拋光"。 可從下面的照片清楚看到，鏡片拋光前、後的明顯差異。拋光之前整片都是霧的，而且表面非常不平滑；拋光後鏡片恢復通透乾淨。 最後的幾張試拍照片可以看到拋光前後的成像有明顯的差異。
拋光救了這支鏡頭！

The condition of the outer surface of the front and rear element of this Kinoptik Focale Fulgior 50mm f/1.3 were very bad. I don't know what the cause is, maybe improper cleaning or natural deterioration, maybe both. The real performance under such condition is not good.
The only way to save a life of this lens is to make a "polish". As you can see from the below images, the condition of the glasses have huge difference before and after polish. Hazy v.s. Clear. The testing sample images also shows the significant difference.
Polish save a life of this lens!!
