Why is the ISO performance always the "catch" on M4/3 systems? Wouldn't you rather have less Mpx but keep same ISO performance as Full Frame Pro DSLR? Imagine you take the 36Mpx sensor out of the Nikon D800 and place is inside the Olympus OM-D E-M5 or the upcoming Panasonic GX2. Of course that sensor will only capture the crop 2x format of the Micro 4/3 cameras. If you do the maths, that portion is about 10Mpx! Only 10Mpx! OK! But remember that you will get the same ISO performance as a Professional Full Frame camera, just in a tiny body, no? Sure we would love it! That is what micro 4/3 should be all about. Small and beautiful! Taking a tiny camera to the top of a mountain and enjoy the tour itself The technology is here, no? Cheers everyone!
