As you can see the new 4K GH4 is almost as big as the Black Magic camera, due to being an early prototype it looks a bit home made, as they say “You can’t have your cake and eat it”.

On a more serious note seemingly the picture below is a GH4 prototype being used to produce a promo for the big launch on Friday.



This was spotted on DEFY Products Facebook page posted on the 24th of January and claims to be an early pre production GH4…interesting.

More updated GH4 specs from 4/3 Rumours

1) It will have a quad core processor.
2) Sensor reading is 50% faster then GH3 so much less rolling shutter.
3) Maximum bitrate of 200Mbps ALI and 100Mbps IPB
4) 4K, you will have MOV + MP4 only.
5) In 1080p you will also have AVCHD.
6) The camera will have focus peaking and the user will be able to change the color. Focus Peaking will also work from smartphone through wifi.
7) Focusing will be faster and have more AF points (compared to GH3).


Having been working in the video business since 1988 I have amassed a great amount of knowledge of both the kit and production values over the last 30 years.

  1. I think that this camera could be my debut into using DSLRs for video as well as my first step towards 4K.

    I can see that filming interviews in 4K for jack-of-all-trades-do-everything-myself types like myself will benefit from being able to reframe without losing any quality when outputting in HD 1080p.

    Looking forward to tomorrow’s announcement and hoping it won’t disappoint!! If it does, please let me have a slice of your GH4 cake!! 🙂

    HDW : Plenty of cake left over a slice is on its way 😉

  2. The specs look almost as good as the cake. I really can’t imagine how they’re going to mess up the recipe unless the image is baked in.
    This is potentially what many of us have been waiting for – broadcast codec, usable viewfinder, XLR audio with a large enough sensor. Smells good – now ready for a taste.
