發覺大光圈時影出來的相片是完全沒有問題...但將光圈校到F.20左右...發覺出來的相片有好多一點點黑色的東西..想請問聲係咪D塵通常係細光圈時先會發覺到呢...謝...

加相作REFERENCE...可以見到有很多黑點...

係, cmos 入塵

[cherryan]

唔好意思。。想再問吓大家通常會拿去ＣＳ抑或係會自已攪除塵呢？？

只要光圈唔好用細過f/11影就得啦, 光圈細過f/11一來成像質數下降, 二來見到塵.

CCD除塵方面可以DIY用Swab, 果凍筆, Sensor Cleaning筆(好似鏡頭筆, 但Sensor專用).

拿上cs, 多謝3舊水
清完一陣又返來
小弟不才...自問影咁耐相, 真係好少用到f11以上
