more myth than fact. so here is how it works... technically a smaller sensor has smaller pixel sites. however if you stop here you are wrong. this completely fails to take into consideration then lens in the equation, especially if the lens is made for that sensor size. as example, a 1/3" camera matched to a 1/3" lens. the 1/3" lens condenses / shrinks the image size for that sensor. this increases the photons/mm - another words it makes the image projected on the sensor smaller and brighter. this in practical effect compensates out for a loss of sensitivity due to smaller pixel sites.

this is exactly what the metabones adapter does - it projects the lens's rear image projection down into a smaller area, making it brighter ( increasing photons / mm ). this is what makes for that 1 stop increase in brightness. its simple math and physics, nothing more. therefore if you use a lens properly matched to the sensor, sensor size becomes far less of an issue in terms of sensitivity.

'small sensor which compromises low light performance'

That kills it for me.

The GH3 is truly great for videographers, only limited by its small sensor which compromises low light performance.  It costs a tad more than the Nex too and also bizarrely lack focus assist/peaking.
Here's a thorough review:

Forgot to mention that the NEX family also can get the metabones speedbooster that does wonders, giving FF angle and gaining 1 stop in aperture!

Yes, except AVCHD on the Sony at a maximum 28 mbits vs h264 at 72 mbits on the GH3 if video record quality is really important to you.

Hi,

I'm looking for a camera with as many as possible of the below features. Currently using a Lumix LX 7, which does surprisingly well for a $400 camera mainly designed for stills/

1.    Compact
2.    Tapeless
3.    1080 24p. 30 p. (60 i optional)
4.    Better (i.e. less)  compression than the 34:1 of my Lumix  LX - 7.
5.    Mac- compatible software.
6.    No 4 gig file limit.
7.    High speed shooting for slow mo.
8.    Good optics -- ideally comparable with Lumix
9.    Better zoom ratio than LX 7
10.    Ideally can shoot high quality 5 MP or better stills.
11.    Long shutter speed shooting for in camera blurs
12.    Good low light performance.

My Lumix LX 7 has all but 4, 5, 6, 7, 9

Thanks.
