"Equivalence" and what you really need to know
In reply to walkaround, Apr 27, 2013

Lots of arguments over "Equivalence" in this forum.

What you need to know is that while FF sensors are "2x" larger than Micro Four Thirds, when you look at DxO over all they are NOT 2 stops better.  For some measurements they are, but for most they are not close to that.

The speculation is that because sensor cost to manufacture goes up exponentially, the best technology doesn't make it to the larger sensors.  Of couse 5 axis IBIS in a few cases can gain you more than 2 stops which is helpfulif you shoot non-IS primes. 

Here is an example.  The 800e is better, but not the 2 stops claimed.
