你們就好啦!有得check 死/光點!

我星期二買左網上行A40, 無得CHECK. 仲話唔包死/光點!

依家影左幾張, 仲未有死/光點出現

我去永成買機要求佢check佢都好樂咁做~
check下配件齊唔齊,o的制係咪全部work~
仲要問埋係咪包乂死點光點,
唔係反轉頭都得拗，
但大公司多數換俾你呢~

DC Fever 服務好好，都十分值得推薦

即係搵員工check唔係自己check?
咁除左光/死點,仲有無其他?

[walkingfuture]

apart from dead/hot pixel and key..etc. also need to check:

1) battery contact, if already replace, the contact may have a little bit sketched.
2) check serial number is matched(body and warranty card)
3) check CF slot is ok or not. check battery cover is ok or not.

then how to check dead/hot pixel?

[walkingfuture]

If you are checking the dead/hot pixel during buying, you should:
Step:
1)using some dark enough to cover the lens carefully, be sure don't touch the lens but need to ensure no light enter to it.
2)set M mode, and MF, shoot two picture using 1/125s or faster. these two shoots is for testing dead pixel.
3)using same setting shoot two photos using longest shutter, say, 30sec.
these two for testing hot pixel.
3)point to white object, using the flash also, set the same setting as step 2, and shoot 2 pictures, these two photo is to test dead pixel.

then reveiw the photo and zoom it the largest, check the photo carefully each by each. if dead pixel occured, you can see some differenct color dots. If hot pixel, you can see some gray.

If you are check it at home, you can just using software to check.
