P. ANGENIEUX PARIS 90mm f/1.8 Type P1 前鏡片嚴重變質損傷拋光 Polishing treatment for front surface severe deterioration and scratches

這支 Angenieux 90/1.8 P1 前鏡片有嚴重的點狀變質以及許多刮傷，鏡主送來拋光處理，希望能夠讓它恢復乾淨清透
大面積的點狀變質是這一款鏡頭典型的問題，輕者不影響成像，嚴重者會整面鏡片霧矇矇的，拍出來的照片也會有卡一層薄霧的感覺
前鏡片是一體成型鑲在金屬框裡，必須用特殊工具小心將金屬包邊切除，才能取出鏡片。在完成拋光之後，再將鏡片封回金屬框裡
鏡片在完成拋光之後，恢復乾淨通透，處理前後有極大的差異，拋光並不影響鏡頭原本的表現，也讓這支鏡頭得以重生
最後幾張實拍照，是完成處理之後的測試照，成相依舊犀利！

This Angenieux 90/1.8 P1 had a severe glass deterioration and scratches. The owner wanted me to make a polishing treatment to make it usable again.
The front glass was embedded in the metal ring, and need a special equipment to cut off the thin metal frame to take it out for polishing.
After polishing, the front glass looks clean and clear, and has a big difference to its pre-polishing condition. The polishing treatment won't alter the lens performance and make it reborn.
