Hey everyone long time no see! Finally got some time to post
Anyone of you using PEN E-PL1? In fact, I think E-P1 and E-P2 users can also feedback. Do you guys notice hot pixels (kinda like bright spots looking like dusts in dark shots) on your camera? I have been taking night shots recently and I see 'stars' in the sky which I later realized is the hot pixels!
The easiest to reproduce is to place the cap on the lens then take a dark shot. Set ISO to 1000 at any aperture value and take the shot. I see a lot of these bright spots on the frame. Most of the time at the same locations. If I reduce to ISO800, the problem isn't so noticeable. At ISO100 its completely gone no matter how long the exposure time is.
I tried using pixel mapping function but it doesn't do anything. This was different from my previous encounter of bright pixels where I see a bright spot on normal in door shots (although ISO is also 1000). It was removed via pixel mapping.
I am thinking of sending the camera in and letting them check it. It doesn't make sense. Night shots filled with 'stars' or 'snow'.
Tried on my e-p2. no bright spots.Anyone of you using PEN E-PL1? In fact, I think E-P1 and E-P2 users can also feedback.
