應該要check d咩?
死點又點check?

[patwong]

check機身鏡頭
再影全黑(ISO100, small aperature, faster shutter, cover the lens, use MF)
再影全白(ISO100, large aperature, slow shutter, face the lens to light source, use MF)
Check Black / white photo any color dots (CCD/LCD dead pixel if show those dots)

Check flash, check some function key,
take few photos and review.

check zoom also.
