一般公司出 DC 既時候
有冇話幾多點CCD 死點包換
定係有一個特定的數量?

我在"空襲電器"買個時,同sales問得好清楚,佢就口頭承諾,話有死點就一,兩日盡快攞返比佢換,一點都得! 總之面對面時問清楚&如果無信心的話,就好似我咁去d大型連鎖店,比多少少錢佢地賺,自己買個安心....

ccd 係唔應該有死點暨(至少你睇唔到)，你只要發現到就算一點都應該換！但 Lcd 就唔同，因為唔影響成象所以每間公司都唔同。大慨係四點之內都唔換。呱！

咁點先可以知道ccd有死點呀?

I asked Canon before, they will not replace your sensor for <0.1% dead pixels (CMOS), if I remember correctly. (?0.01%, sorry bad memory)

There is free software, when you shoot with your lens cap on, and then run the program, it will show you the number and location of dead pixels on your sensor. But I don't have the link in this computer. Will try to look for the link tonight at home.

Happy shooting.
