> my school has just got the Rokinon Cine Lenses kit And i wanted to Be 100% sure that i could use those lenses on the GH4?? if not what adapter do i need?

Rokinon makes cine lenses for Canon, Nikon, Sony and micro 4/3 mounts. We would have to know which mount is on the lenses before we recommend a specific adapter. Sorry.

That said, when you find out what adapter you need, you can get one for less than $20, e.g. [Referral Links]:

Canon EF lenses need power for aperture control and autofocus. If your Fotasy adapter is [this one] (http://www.amazon.com/Fotasy-AMEF-Thirds-System-Adapter/dp/B003150B6O/), it is the same one I have. It provides no power to the lens, so focus is manual and aperture is stuck wide open.

You need a more expensive powered adapter from [Commlite] (http://www.amazon.com/gp/product/B011I2WWQ8/ref=as_li_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B011I2WWQ8&linkCode=as2&tag=battleforthew-20), [Kipon] (http://adorama.evyy.net/c/60286/51926/1036?u=http%3A%2F%2Fwww.adorama.com%2FKAELAM43EOS.html) or [Metabones] (http://www.amazon.com/gp/product/B015NB037U/ref=as_li_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B015NB037U&linkCode=as2&tag=battleforthew-20) [Referral Links] to get auto-aperture, autofocus, and/or image stabilization to work.

Sorry I couldn't be more helpful.

no autofocus, no metering, no aperture control (however, you can set the aperture by putting the EF lens on a canon body, stopping it down, holding the depth of field preview button and removing the lens)

The kit lens that comes with the G7 is pretty sharp for a kit lens, but it's aperture doesn't get very wide. It's overall pretty good for a beginner, because of the ISO sensitivity of the camera it's less important to have a lens with a wide aperture. That being said, it's not perfect for everything and one of the first lenses that many G7 shooters get after they've outgrown the kit lens is the Panasonic 25mm f1.7.

And yes, one of the advantages of the Micro Four Thirds sensor and mount system the Panasonic G7 uses, is its wide compatibility with adapted lenses using either a basic "metal ring" adapter, a focal reducer (which reduces the crop inherent to the Micro Four Thirds format while adding an extra stop of light to your lens), a smart adapter
(which retains electronic lens features like autofocus and image stabilization), or a speedbooster (which does the job of both a focal reducer and a smart adapter in one).

boom. I've used this for about two years now with no issues.

I use this adapter on my B-Cam and I enjoy it. There is no glass, it's just a metal tube.

Hey, there!

I have a G7 as well as a Canon EOS camera with EF-S lenses. So far I haven't been able to find an adapter for the EF-S lenses to fit the G7 which have a focal reducer / booster. The only ones I've found which do work are the adapters with no glass in them. It's just an adapter to fit the lens onto the G7 body. They work but you'll need to keep in mind of the crop factor. Mine was about $15 from Amazon. It's this one: Fotasy AMEF Canon EOS EF Lens to M43 Micro Four Thirds System Camera Adapter

Hi /u/agomez470 - that's a great article, but it doesn't cover the specifics of adapting your EF lenses to micro 4/3.

You have three choices [Referral Links]:

Smart adapter:

• [$598 for a RedRock Micro LiveLens adapter MFT] (http://www.amazon.com/gp/product/B006MKE4AE/ref=as_li_ss_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B006MKE4AE&linkCode=as2&tag=battleforthew-20), which will power your lens while it is on the GH4, allowing you to set your aperture electronically. But it's expensive.
  
  Adapter with manual aperture:
  
  
• [$32 DSLRKIT EF to MFT adapter with aperture control] (http://www.amazon.com/gp/product/B007KG4QKC/ref=as_li_ss_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B007KG4QKC&linkCode=as2&tag=battleforthew-20) - make sure the aperture on your EF lens is wide open, mount it on the GH4, set the aperture with the adapter and shoot. Simple and relatively inexpensive.
  
  Adapter with no aperture control:
  
  
• [$94 Canon EF to MFT Speed Booster/Focal Reducer] (http://rover.ebay.com/rover/1/711-53200-19255-0/1?icep_ff3=2&pub=5575034783&toolid=10001&campid=5337235943&customid=&icep_item=281240980971&ipn=psmain&icep_vectorid=229466&kwid=902099&mtid=824&kw=lg) or [$16.59 Canon EF to MFT adapter with no aperture ring] (http://www.amazon.com/gp/product/B003150B6O/ref=as_li_ss_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B003150B6O&linkCode=as2&tag=battleforthew-20) - these adapters would be great for Canon EF mount cine lenses with aperture rings (especially the Focal Reducer, which gives you an extra f stop and a wider FOV), but for Canon auto lenses, you would have to carry a Canon body on every shoot, set the aperture, take the lens off and put it on your GH4. Not very practical.
  
  Bottom line - you can get the GH4 and adapt just about any lens to it, starting with your existing lenses.
  
  Hope this is helpful and good luck with your new camera!

As per here

you should :

> Pull the trigger pin on the adapter towards the body of the camera and turn the lens counter clock-wise while you are facing the front of the camera.

here are some examples,
Basically you use one of the adapters to make certain type of lens fit on to your camera. Micro 4/3rds is unique in that you can adapt more lenses to it that most other sensors because of the field of view.

Not OP but I'm in a similar boat. I have some Canon EF lenses, from looking around on Google this seems like it should work https://www.amazon.com/Fotasy-AMEF-Thirds-System-Adapter/dp/B003150B6O


Curious why that one is so cheap compared to B&H ones that are listed >$200. Just cuz it requires manual focus?

Would that one do the trick?
