o岩o岩買o左部20D,用最高ISO同30秒影o左兩張相,發覺有十幾點死點,
而家我可以點做??去代理換機定維修??謝謝各位指點
心急人

Is that are hot pixels?高ISO同30秒影相 may be have some noise.You can open NR and test again.

Thankyou fisichella 但係o甘o既情况是否正常??有無須要維修or更換??
Thanks

試下最快快門影...如果都有死點就一定要換...
依家有可能係hot pixels...

You shouldn't use "最高ISO同30秒" to test blind point. What you see is hot pixel, in other words, noise.
Check again using ISO 100 or 200 at 1/30s or above. If that is really blind point, they will show up again nomatter what ISO setting.

你響度曬命多D....

我用Olympus E-10 最低 ISO 15 秒, Hot pixel 多過實景 Tim...

Thankyou 各位大佬,但都係想問是否正常呢?

[korea]

Then, are you asking whether noise in DSLR is normal in high ISO setting?
That is a very good question. Canon, Nikon, .... will answer that is normal in other brands but .....

Andy3210兄: 似係你自悲多過似佢曬命喎....哈哈,講笑嗟,勿見怪.

我都覺得似係熱點多.

當年用 E-10 Set 去最高 ISO 真係天方夜談, Noise 多到振, 不過到左依家 OM 依然有呢個問題.

[gaiuswong]

唉! CCS size細點都係先天缺諂,4/3係好不過...唔計noise表現,冇計,死症!
