我係一個新手黎,
用緊450d,
我尋日拎左去影夜景先發現
當收細左個光圈(e.g f/11)會影到幅相右上角有粒暗點(細細粒, 但係都幾覺眼)
但較大左個光圈(e.g f/2.8)又唔多覺眼有
試左幾支鏡都係咁
於是我試下反起個反光鏡又唔覺有塵
我想知其實係咩問題, 唔該~

你係見到定影到? 影夜影好難會影到塵!除非粒好大o既塵o係正一d好光o既大廈道! 否則要影d好光或者白色o既野先會發覺粒sensor有塵!

CMOS dust, can be clean by air OR go to CS to remove

原來真係cmos入左塵 聽日買支氣清一清先
thx you all~

[Obi-Wan]

after cleaning with air, it should be ok. BEWARE don't point the jet too close to the sensor low pass filter

It will be fine unless u turn that can upside down!

450D有無得set dust data?
有就用住先~儲到咁上下先一次比CS清~
講緊可能係半年至一年一次~
都唔算好過份~

吹就睇屋企環境了...
我屋企本身較多塵...
唔吹好過吹...

SENSOR SWAB睇個人勇氣了...

How much is needed if go to CS for removing the dust??

[zeven]

傳說中係300
當比錢買個保險啦...
有咩事...佢地賠咋...

APS機SENSOR平D都有點勇氣去攪...
小弟而家轉左FF...唔敢攪了...

I just use air to clean the cmos of 5Dmark2

"原來真係cmos入左塵 聽日買支氣清一清先"

我建議你就最好唔好用壓縮氣吹啦, 因為壓縮氣吹出黎既力太大, 又有機會會越吹越多塵, 其實如果CCD/CMOS有塵, 可以試下之前用機本身既自動除塵功能clean幾次, 再lock左個反光板, 用手泵吹下個CCD/CMOS就ok, 當然個手泵係用之前最好先對住隻手吹返十次八次先就最好, 因為手泵有時放得耐都有機會有塵.

試睇睇可唔可以幫到你。
