Cool sticker for GH4 owners!

Vincent Follézou created that super cool GH4 sticker. He sent me that text:

I have created a very useful sticker to put on the back of your Panasonic GH4. It will give you a ton of information like the focal length of you lens using a Metabones Speed Booster, flicker free shutter speed or shutter angle, recording time, stops filtration with ND filter and lot more…
Perhaps it could interested some of your reader.
