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.
