CANON TV LENS 50mm f/0.95 脫膠/離膠處理 Treatment for cemented lens group separation

CANON TV LENS 50mm f/0.95，這支夢幻般的鏡頭整體狀況很好，不過它的前膠合鏡組有明顯的脫膠/離膠的問題需要處理，第一片鏡片邊緣長了一些霉絲需要清理。
霉絲可輕易的清理乾淨。脫膠/離膠的問題也非難事，不過就是過程繁複需要特別細心處理。
脫膠/離膠的處理過程在之前的文章中都有敘述，大致步驟就是取出有問題的膠合鏡組、分離鏡片、仔細清理殘膠、清潔鏡片、點膠後精準對位重新黏合、重塗鏡壁黑色避光漆。


This Dream Lens, CANON TV LENS 50mm f/0.95, has a great overall condition, but has a front cemented lens group separation need to be resolved, and slight fungus on the edge of front glass need to be cleaned.
Cemented lens group separation was a fetal problem to a lens, but now it can be totally repaired under careful treatment. It is not difficult but a complex work that involves multi-procedure, such as taking out the cemented group with separation problem, taking apart the cemented glasses, cleaning the residual glue, cleaning the glasses, dropping a new glue and re-cementing with precise collimation, applying new black paint to sidewall.
Once the problem be resolved, the lens can be used for a longer time.
