I didn't have much time to check out the gh4 so far, a lot of work hinders me, going too far into research for each little thing myself, that's why I hoped I could get a little support from you hear. Mostly I'll record video and sound on myself at the same time, not sure if I'll have an assistant from time to time. My idea until now is to record in 4k, maybe in 24fps should be alright I guess. The shooting will be for a 5 video monitor/large flat screen panels installation.

My equipment so far: GH4 with kit lens 12-35mm

• Voigtlander Nocton 17.5mm 0.95f with UV and ND filters
• Voigtlander Nocton 42.5mm 0.95f with UV and ND filters
• One SD card SanDisk Extreme Pro 32GB 280 MB/s (I'll have another one like that)
• only one battery so far
• trolley case

I'll definitely need a second battery or the battery grip, is it a good thing to have?

• Sound Recording device
• Microphone (one or two? maybe too much to handle!)

• Wind jammer (boom?)

• Any experiences with 'Rycote Zoom H5 Audio Kit' or 'Tascam DR-60DmkII 4-Channel Portable Recorder with Rode NTG2 Condenser Shotgun Mic Kit'?

• Tripod mainly to use as proper stand in any condition, not sure if I'll need a very heavy one for doing pans?

• Rig / steady cam? I actually would prefer shooting with a rig/steady cam to make pans with a heavy tripod. Follow focus! Which one?

• A super-portable extra light like dedo light!

• SSD discs for backups?

• A Mattebox?

And everything should be of proper quality, lightweight one-person-solutions, possible to get through the airports O.K..

Thanks, I appreciate your hints, ideas, experiences and comments ! kolinko
