係uwants見有人問~但覺得呢度既ching答案會可靠，所以問問

用放大鏡望一定有幾粒塵
肉眼望不應該望到有幾粒塵

[albert18]

No

[albert18]

No, 除非用顯微鏡望, 一定有幾粒塵 !

日本制少d，中國及馬來西亞制就多d

[小小生]

我見好多日本制的L鏡,又話防塵防乜一樣好多塵-__-!

Uwants 果邊人話買鏡用電筒照就會有好多塵~佢話sales都咁講~
如果咁點買得落手~講到勁誇

>>電筒照就會有好多塵

That is true wor. Even new lens will get.

But these tiny dust will not affect optic standard.

電筒照 we like to see more about 磨損, 霉點, etc.

Here is the link how Ken Rockwell explain 電筒照

ic ~但即係新鏡~幾貴都好~點都有幾粒塵係入面？

[ssannwong]

>>新鏡~幾貴都好~點都有幾粒塵係入面？

If the dust is big enough for you to see without using 電筒, of course that is not good & you can ask for another new lens la~

But yes there is always tiny dust in the new lens. Unavoidable.

電筒照 is very good method to check lens. But have to know how to understand what you see, so you will not overreact & miss the good lens~

咁樣架~但如果好似買小白2~人地根本冇咁多俾你試同要俾錢先

[ssannwong]

Using more than $15K to buy a lens. Trust the quality bring from cost la ^^

On the other hand, when you open the goods you see the problem you can

1)ask for another new one to change

2)if store don't change for you. Go to Canon Customer Service & they will be very kind to fix your NEW lens.
