    Hi All,

    I bought my e-pl5 yesterday. It had bunch of hot pixels which can be even seen from LCD screen. I ran pixel mapping after finding solution on the web. Then it disappeared completely. To test this I took few pictures with camera cap on at iso 400 at 1/8, 1/3, 1", 2" ,4", 8" and 10" in Jpeg. No hot pixels or dead pixels were visible as per StarZen Technologies, Inc; DataFlex tools and books software.

    However, when i took a ISO 3200 shot of a dark area some artifacts were visible. Please check the attached image. Please advise whether the sensor is s defective one or are these due to noise.

    I had big hopes of this camera after reading numerous positive reviews. but now bit disappointed. Please help me
    I bought this from another country and possibility of exchange is limited.

    Check out 'pixel mapping' to get rid of it :smile:
    Then again, I've never taken any shots with the lens cap on mine :wink:

    Hi panther, thanks for the reply. Actually i used pixel mapping. After that i shot atatched image at iso 3200. If you can see the attached image it contain some artifacts. are these noise or a sensor issue?
     
  4. How long was the exposure of the ISO 3200 image? For longer exposures, every sensor will display hotspots. The use of a high ISO value probably increases the likelihood of hotspots developing.

    I have e-pl5 and I am not aware of this problem. Mine looks ok to me, but I am not an expert and never really examine the LCD.
    I cannot see artifacts in your attached image. But maybe it's just my eyes.

    hi andi , if you click the image and view the enlarged one which is a 100% crop, I hope you can see bright white, blue and red pixels in the black background

    I wouldn't worry about it.

    All cameras will have hot pixels at some point. They come and go. If it doesn't affect the image, then it should be okay, but if it really bothers you, then return it.

    I can see some faint white dots like dust (The hot pixels), and a faint reddish shadow that starts about 1/6 of the way up from the bottom on the left and slants down to nothing about 5/6 of the way over. Is that it? Maybe the lens cap isn't completely light-tight.

    I've just sent my e-pl5 affected by high iso (3200) white dots to assistance.
    Will let you know how things go…

    I only get them on my E-PL5 with long exposures, so I guess I'm lucky!

    Is the issue with the LCD or the sensor? If it's just the LCD I'd be inclined to leave it if it's not too bad. I've had hot or stuck pixels with almost every device with a display.

    Normally I'm always unlucky with stuff like this. I just checked again and I do get hot pixels but they are just single pixels and not visible on normal photos.
    I never shoot in iso 3200 in combination with high iso's so I'm not to bothered.
    I hope you get it fixed soon!!

    Mine are pretty visible at 100% crops, on dark background, and they are, say, around 50 I guess. They shouldn't be there.

    Thank you though.

    No LCD. This is a sensor related issue.
