想問大家:
推拉鏡的入塵有什麼影響? 成像, 操作, 防水? 哪方面有影響?
唔該, 唔該

操作, 防水...no effect........these have no relationship with
whether the len has dust or not lei...

I thing 成像 -0.1% for each dust inside the len..
XD

so unless you have many many many dusts; you don't need to take it for cleaning

but of course dust could affect your 心理...

乜鏡都會入塵,新鏡巳經有,程度問題者,少用入塵又會少D,最好唔用!!

憑乜野咁計架，豪模理據

咁canon 白鏡又話有防塵ge?! 咁又係咩回事?

[baronng]

> 咁canon 白鏡又話有防塵ge

not correct
from what I know, canon 大三元 and 17-40 f/4L (plus a few more at most) 係防水防塵

保養期內不包清潔lens內的塵合理嗎?

[letni]

咁o個d canon 大三元 and 17-40 f/4L (plus a few more at most) 的防塵又係唔係塵唔會入lens入面?

[kcpun]

防塵？吹水咩！

Can anyone recommend shops which clean lens with inexpensive price? I have an old lens with some dust and "mo". Not worth spending to much on cleaning.
