EM5 is 16.9MP total according to the review and Olympus site
In reply to Jorginho, Sep 20, 2012

Jorginho,

I agree that these little differences do not prove that the sensors are different, especially ISO options and AF points. But total pixels (when the numbers are correct) is more a pure hardware spec, and it is 16.9MP for the EM5 according to the review at
http://www.dpreview.com/reviews/olympusem5/2
and Olympus itself at
http://www.olympusamerica.com/cpg_section/product.asp?product=1583&page=specs
so different than the 17.2MP for the GH3 according to
http://www.dpreview.com/products/panasonic/slrs/panasonic_dmcgh3

The specs for the EM5/EPL5/EM2 look more different, in particular the 35 CDAF points instead of 23 as for the GH2, G5 and GH3.

True, but this has little to do with the sensor I think. I think this is the read out of the sensor (?)

Other differences that are less solid evidence of a difference:

  • 16.9MP total pixels instead of 17.2MP for the GH3.

No, it is both 17,2 MPixels according to dpreview.

  • ISO 25,600 option on the EM5.

No, it is both 25600 (but one is extended ISO range, don't know if this matters much).

Smaller lenses, better in low light, more telephoto reach:
you can have any two at one time.
