I have a big concern about the E-M1's sensor performance. Here is an issue that only very few M43 folks have addressed so far, and missed by lots of E-M1 reviewers.
Why does E-M1 performs worse than E-M5 in low light situations and with longer exposures?
1. Is it a common problem with all E-M1 units or found only in first October-November shipments?
2. Can we expect the issue to be fixed or it's here forever because of the way E-M1 has been engineered to implement a new Dual-Fast AF sensor with AA filter removed?
Olympus representatives didn't give my any reasonable answers yet.
I am wondering if DXOMark, known for its high-grade testings, can cast any light here.
