Re: dark current noise

Real world comparisons posted here with different Oly cameras.

I know there are some there from the EM1 and EM10- not sure if any from the EM5 are in there but they should be.

I posted that in a thread in the astrophotography forum because people were telling me that MFT cameras have too much dark noise to be used for astrophotography.  They told me ISO above 800 cannot be used.  I found images of very good quality all the way to ISO 3200 (at 30 second exposures) and ISO 1600 (1 minute exposures x10 stack) with both the EM1 and the EM10.  The person who was saying that MFT cameras have too much dark noise to be useful above ISO 800 for long exposures has an EPL-5, that's why I was wondering if there is a difference with the smaller bodies vs the larger ones- but he also had dark frame subtraction turned off.
