NEX-7 vs VG20


New to TalkEmount
These cameras seem to share a lot in common, despite the obvious differences. I'd like to buy one unit for both video/film making and photography, and they both seem quite promising at both taks.

What are the actual differences besides the obvious form factor difference?

so far i've found
- VG-20 has the additional 5.1 sound recording capability
- VG-20 has a touch screen with focusing features

any others? thanks
