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!

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.
