有400D既師兄,個自動除塵OK碼?

如果唔得....自己會唔會比無自動除塵既機難架...因為多左塊除塵片喎...

[K_C]

有自動除塵好過無啦, 不過都要定期吹一吹反光板及開起塊反光板吹粒CMOS.

Sorry寫小了字..

[如果唔得....自己"手動清潔"會唔會比無自動除塵既機難架...因為多左塊除塵

片喎...]

其實我想問,係咪多隻香爐多隻鬼.

因為朋友話DSLR成日要清CCD(佢用D70s),佢最初由SLR轉DSLR無留意

呢樣野,搞到成輯相廢哂.(不過佢又話清CCD係樂趣 =口=")

而400D既自動除塵比D70s多左塊除塵片,

1.唔知D塵會唔會留係/走入COMS同塊除塵片中間

2.又唔知如果吹唔走D塵,要用CCD清潔液時,

會唔會留左清潔液係COMS同塊除塵片中間.

3.自己"手動清潔"係咪好有樂趣.....=.=+

其實我真係唔覺有咁多塵law,之前我用350d成2年,冇乜入過塵, 試過有,但基本用氣泵都吹得走.只要換鏡頭時機身向下,小心的未冇咁易入塵law.
我覺得除塵裝置同某冷氣機自動洗隔塵網功能一樣, 都唔係必須既,仲有wor, 我有個奇怪唸法, 多左個機器幫你洗隔塵網, 咁個機器本身你咪又係要清潔?唔通第日又有個自動清潔呢個機器既機器? haha

咪聽D人9 up 24整色整水la, 求其用bump 吹幾野就得嫁啦

ccd唔洗成日清潔架?? 無必要都唔好搞佢喎!
否則整花咗咪仲衰???

有時收光圈會影到d點點, 好多時都係塊UV有塵, 而唔係ccd...

[petercheung]

請問如果我只用支Kit鏡,都唔會換鏡的,咁係唔係不會入塵呢?

[man1492]

應該唔會

多隻香爐多隻鬼.

-> this is the reason of people who support don't use the protective filter at lens. However even don't use the filter at lens, the low pass filter at CCD still exist.

Do anyone know the low pass filter has ED, multi MRC coating which don't adversely affect PQ ?

[Rol]

Also VR / IS lens need extra lens component for vibration correction. Then will it affect the PQ too ??

Because some people explain Nikon LB4 (without VR) is sharper than LB5 (with VR) is this reason
