GH1 - How to Hack Guide (GH13, GH17)

GH1 - How to Hack - Part 1 - PTool Settings

GH1 - How to Hack - Part 2 - Firmware Install & Camera Settings

Vitaliy Kiselev, has done the impossible. He has made all Panasonic Lumix GH1 cameras, "Hackable". This enables end users to dramatically increase the data rate and performance of these pint size cameras.

What was once a handicapped camera, due to it's laughable compression schemes, is now a professional grade camera, shooting images that rival cameras costing up to 10 times more.

I currently have 2 of these "Hacked" GH1's, now referred to as GH13 and GH17 by Vitaliy. I have never felt the need to jump ship and go with the more popular, and more expensive, Canon 5D Mark II. I am quite happy with the amazing quality and ease of use that these little monsters provide.

For those of you who want to hack your GH1, but are a little worried about "bricking" your unit, I have put together these step by step videos to help take the stress out of the process.

I have also come up with my own custom settings that I think offer the best quality and reliability for the independent filmmaker.

  • Based on settings from LPowell & Vitaliy
