Reddit mentions of Metabones T Speed Booster Ultra 0.71x Adapter for Canon Full-Frame EF-Mount Lens to Micro Four Thirds-Mount Camera (MB_SPEF-M43-BT4) 4PC Accessory Kit

Congratulations on the new work - and the new camera! I am a GH4 shooter and it's a very capable video camera.

Assuming you already have sound and lighting taken care of, here are my recommendations [Referral Links]:

• A gimbal will improve your production value faster than just about any other expenditure - [here] (https://youtu.be/oW-VnyqubSY) and [here] (https://youtu.be/bTYH3P3cudY) are a couple of example videos from the GH4 mounted on a [$398 Sabre Digi] (http://rover.ebay.com/rover/1/711-53200-19255-0/1?icep_ff3=2&pub=5575034783&toolid=10001&campid=5337235943&customid=&icep_item=121820485260&ipn=psmain&icep_vectorid=229466&kwid=902099&mtid=824&kw=lg).
  
  
• I recommend the [$99 V-LOG L upgrade] (http://adorama.evyy.net/c/60286/51926/1036?u=http%3A%2F%2Fwww.adorama.com%2FIPCVL.html) if you don't have it already - it will give you a couple of extra stops of dynamic range and improve the camera's performance in low light.
  
  
• Finally, if your Canon EF to MFT adapter is not a [0.64X Metabones Speed Booster XL] (http://www.amazon.com/gp/product/B016P0ZZLC/ref=as_li_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B016P0ZZLC&linkCode=as2&tag=battleforthew-20), you might want to invest in one to reduce your crop
  
  Smooth, gimbaled 4K GH4 images can look really good with Canon mount glass and a Super 35 equivalent crop:

• [Sundays Episode 57 - That Bank Spot by peter w.] (https://vimeo.com/147135697)
  
  Hope this is helpful, good luck with your business and Happy New Year!
  
  

This Speedbooster has the best crop ratio for most Canon glass, including APS-C.

Please note that everyone is waiting for a firmware update from Metabones to fix some issues they have been having, specifically an issue with zooms. You have to hold the button down on the Speedbooster when you power on the GH5 to work.
