Question about DR for various sensor sizes
In reply to Anders W, 8 months ago

Could you briefly explain why dynamic range for smaller sensors is often very close to what it is for larger ones?  For example, IIRC, the E-M1 at most ISOs has DR within 1 EV of D800 (And almost identical at ISO12800).  This goes against the myth that there should be a 2 stop difference between the M43 and FF sensors.  Is this due to pixel size?
