So after having reorganized my office after a move and and some office remodeling... I started to go through some boxes and came upon my sweet little Sony NEX 5N and realized I have never really used it as much as I would like to due its small size and having to attach all sort of add ons like a Zoom Mic or an LED video light plus adding these things to a flash bracket was kind of weak and not to mention how silly these tiny cameras look on a full size DSLR cage.
Given these were made small to fit in your pocket and give you some what full control like a DSLR, but the accessories mic which is sold separately for the NEX is anothe $139 and is very crappy at that. So a a better solution would be something like the Zoom H1 which provides amazing sound for way less and not that much bigger than the Sony NEX mic.
You might also want to add a light on it, and these cameras have propiertory adapter sockets and no hot shoe mount so you would have to get a flash brack attach it to the bottom of your camera and then attach your Mic and Light to the flash bracket.
Gini has an awesome cage for smaller cameras made specifically for the GH1 & GH2 but at around $200 / $400.
My version will run you around $20 / $25 maybe even less with items you might already have at home and 15 to 30 minutes of easy fun labor.
For those of you going about "Oh its plastic!" you dont need to add and remove screws to your cage I used these TRECK-TECH MAG CONNECT SYSTEM MAGNETS which are super strong, as you can see in my video.
