Re: dark current noise

I own a EM5 and EM1.

Both can do great shots of night skies, but the EM1 really needs darkframe subtraction at 8 seonds and longer exposure.

EM1 versus EM5 dark current noise (with and without darkframe aka "NR")

EM5 is easier to handle regarding dark current but on the other hand it adds some magenta color cast to the hight iso/low light exposures. With darkframe and exposures at 30 seconds, I prefer the EM1. Without darkframe (star trails) and very long exposure I prefer the EM5.

I think the PL6 you mentioned is similar to my EM5 including the magenta color cast.

Would be interesting to know if ALL newer cameras with the current TruePic VII engine (EM1, EM10, EM5 II, EPL7) have better color cast handling. In this case a camera with Sony Sensor and TruePic VII engine (EM10, EPL7) would be the optimum.
