主旨:Zeiss 16-80MM ZA Lense [SAL1680Z] problem
My name is xxx from Taiwan. I am your Sony 16-80MM ZA lens user. [SAL1680Z]
The serial number is xxxxxxxx [shown in front cover] and xxxxxx [shown in back rare].
As you may hear that this lens have many complain that alot of users discover their lens has alot of small dots in front lens.
I take my lens to a camera shop and the engineer said this is some kind of degum which is not Sony say fungus.
The engineer said the front lens are made by two piece of lens and use special gum to keep bonded. The two lens maybe separate due to gum material defected.
I am very eager to know how will Zeiss or Sony handle this issue.
Please take this issue as your priority and I hope I will not dissappoint Zeiss lens again.
PS: Actually I want to buy more ZA lens for my Sony A33 Camera but this issue keep me away.
I attach the photo of my lens and warranty card. Please push Sony to urgent response this problem.
Thank you and Best Regard,
相機修理公司工程師說是脫膠. 前鏡片是由兩片鏡片組成, 可能膠質變質導致脫膠.
其實我還想買ZA 鏡 給我的A33用. 但是此問題讓我卻步了
有誰知道日本SONY 的 客反email?
我想要email 給 日本SONY.
Sony's 16-80MM ZA Zeiss branded Lense [SAL1680Z] problem
My name is xxx from Taiwan. I am a user of Sony's 16-80MMZA Zeiss branded lens. [SAL1680Z]
The serial number is xxxxxxxx [shown in front cover] and xxxxxx [shown on lens mount]. Attached is a list of other users who have experienced similar problem.
(第一個是前蓋上的序號，第二個是在卡口處的序號，改說為 Sony 的 Zeiss 商標產品。畢竟這不是 Zeiss 生產販售的，避免他們再度解釋一次反而轉移焦點，就先在這邊說了。而下面附上的就是目前我們所知有碰到問題的使用者，序號，與其的問題。)
As you may have heard that there are some/a lot of users that have complained about this lens. All of the cases that was reported to Sony was always classified as fungus growth in lens. Which is extremely odd as there are cases where new, unpacked lens that had this problem upon opening, or the issue showing up after only one month of use.
The symptom varies from flaking of the lens coating, massive amount of bubbles showing up between the glued two front elements, or snow flake/pine needle like pattern that appears more like glue separation than fungus.
Some of us who have taken the camera to camera shops or personnels with experience in lens issues, and the engineers there have also confirmed that the issue is some kind of gas release from glue (bubbling) or glue separation problem (pine needle/snow flake pattern), and none are fungus at all. Some even have reported that the "snow flakes" have grown after the camera have experienced normal vibration of day to day use. (like the vibration caused by car/motorcycle/walking)
(我們有些人將鏡頭送到相機行或是有相關經驗人士處檢查，工程師們都確認這是膠本身的氣體釋放 (細微氣泡) 或是脫膠的症狀 (雪花，松葉)，而完全不是發霉。而也有人發現 "雪花" 會在日常使用下的震動後增加/變大 (車/機車/行走的正常震動)
Those who have examined the lens have mentioned that this could be caused by the glue used to fuse the two front element together. Sometimes when unreliable/defective glues are used, there could be gas release or glue separation could happen. (I guess you guys would know this better than we do, so I won't preach to the preacher.)
We are all very eager to know what would be Zeiss' or Sony's official response.
We hope this issue can be handled with higher priority, and we wish that we won't see this kind of issue showing up on Zeiss branded lens again.
PS: We all would like to purchase more Zeiss branded ZA lenses, but this kind of issue is scaring people off. Many have held off their purchase of higher quality lenses due to this problem.
Thank you and Best Regard,
