On the low light shots I got a cyan pixel stuck in the bottom right area. It seems that pixel disappeared meanwhile but was there for an entire shotting session.
I’ll keep eye on it in future.
Meanwhile I read on dpreview forums that there is a way to force the FW of canon to remap those stuck pixels.
User Bambi Brown says the following:
“I took a photo with my lens cap on, manual mode 1/4s, ISO100 and verified the hot pixel’s there. With the lens still on, I went to manual (not auto) sensor cleaning in the XTi menu, started the procedure, I could hear the mirror flip up, I counted 5 seconds and turned the XTi off. Turned the XTi back on and with the lens cap still on, took another manual 1/4s, ISO100 shot and another at ISO1600. The red hot pixel is gone!”
There are some forum users confirming that.
Note: For seeing the stuck pixel watch the video in HD mode 720p, do a full screen and watch the cyan pixel left to the white arrow.
