Should I buy the GH4 or Canon 5d Mark III?

Sorry for adding to the camera discussions on such an already over-saturated topic, but I really would appreciate a second opinion.
I am a wedding videographer who owns two canon 7ds, 2 Canon L glass lenses, and a variety of other canon and canon mount lenses. I am looking to get a new DSLR.
By now we all know the advantages and disadvantages of each camera, so my question is can I mix the GH4(with a metabones adapter) footage with my other canon footage or should I stick to canon avoid the headache of trying to mix crystal clear panasonic footage with the not as sharp 7d footage?
Also what about the A7s? Will I run into that same problem?

Any help would be appreciated, my budget is around $2000-3000


Your Canon 7D footage is not going to mix well with anything, so I would not be too concerned about matching the look of your 7D cameras. ( i.e. you're going to have to degrade footage from any other camera to get it to look more like the 7D )

I would look at buying a new camera from the perspective of what features do you need most right now. If low-light shooting or shallow DOF was near the top of your list, then I would look at the Sony A7S. Otherwise, if maximum detail and being able to re-frame your shots in post was important, then I would look at the Panasonic GH4. Either way you're going to have to purchase an EF lens adapter for these cameras to use your Canon lenses.

Today I recommend you a blackmagic pocket camera. Is versatile and small. Also cheap.

+1 on that. but id take the gh4 over 5dii any day for video. once you go 4k it's had to go back for commercial work

But note that .. you will want to spend sometime with it... its not a camera that operates on Auto at all you better know what you doing!

The pocket cam, while a great camera, is not ideal for weddings (poor lowlight, high native ISO, Super 16 sensor (that's a big crop), fixed LCD, etc.).

I would sell the 7Ds and get two GH4s and a Hero if you must have a 3rd angle to cut to for ceremonies, speeches, toasts and dances. They're obviously not as great in low light as the A7s but I believe the other attributes (internal 4k, amazing battery life, no moire, etc.) help it edge out the Sony for weddings. I've shot a few weddings with my GH4 and have had no problem at 800 ISO during the last hours of the reception when the lighting is minimal. The dynamic range is great and you can pull a good amount from the shadows.

Hello - late to the party, but will be most likely purchasing the GH4 in 2 months. What lenses do you recommend for weddings? What have you used? Have you used lenses you would NOT recommend? Curious for your thoughts...

I own both. 5D Miii= photography, GH4 + Cine lens= High quality video.

You voted '+1'.

Hey man I literately just bought the GH4 with the adapter and I kept my canon glass b/c I read canon is making moves early next year...So I am going to wait a couple more months to see what happens. Overall I feel like either one of these camera will fit your needs if you do not want to sell your lens yet

Hey there, fellow wedding videographer here.
I've shot weddings with 5Dmk2/3, gh4, 7D, C100/C300.
I consider weddings to be a battle of low light. If you can win that fight, you have a better chance at producing quality wedding videos. Unfortunately the 7D and gh4 lose this fight majority of the time since anything past 800-1250iso looks pretty bad. I still use the gh4 as a back cam for ceremonies so I can crop in with 4k, but past that, it never comes out of my bag. A 5Dmk3 can be pushed to around 3200iso before the footage starts to break apart. Now I've heard great things about the A7s. I've only used it once so I can't speak on its behalf, but the menu system felt clunky like the gh4. BUT, the lowlight is fantastic and will win that fight every time. Honestly, I recommend the c100 since you already have the glass for it. Yes, it is more expensive on all fronts, but it also packs a decent bit of features like XLR audio, fantastic ergonomics, easy menu system for changes on the fly, and you can shoot extremely high ISOs. Last weekend I was at f/1.2-1.8 8000iso most the night and the footage looks great! Of course it all depends on your budget and I know many people might shake their head at me for recommending a camera in that price range, but imho, I thing it is worth it. And I agree with McLoughin, you won't be able to mix 7D footage well with any of the cameras listed.

I agree with Matt, Also the C100 is totally usable at 20,000 iso for wedding if it gets super super dark. Where do you work? If you are near a rental house you can rent a C100 when you need it. I would say that you'll be very happy with the C100... for weddings I don't think you can find a better camera

C100 and a7s owner here. As much as I love my a7s, the C100 is a proper and complete video camera that is easier to use than any DSLR form factor type camera. Although I can take my a7s in darker places, the C100 has very nice colors and very nice skin tones that only require a few tweaks in post unlike the a7s which take more work. I require very fast turn around so every little savings in time helps. Oh another interesting function the C100 is tis dual pixel. I prefer focusing manually but I was surprised how useful was the dual pixel AF was especially in many run and gun situations.

also now that the C100 mark 2 is coming out you may be able to grab a C100 mark 1 cheaper than ever

A7s for its low light and shallow DOF - agreed. These are musts for any event videographer. But no one's mentioned the 60fps at 1080p or 14 stops of DR. Granted, it's 8-bit color, but 60fps at 1080p!? 14 stops of DR? Nab that sucker.

Not a good idea to mix your 7D with a GH4. You'll end up eventually hating your 7D. I'd get the 5DIII since you already own the glass. I currently use a GH3. Sometimes, at night, I wished I had gotten the 5D3 but it doesn't happen that often. The size, ergonomics and weight of the m43 system is so much easier to work with. I probably use the flip screen on the GH3 90% of the time when shooting. Just my opinion.

...forgot to add....I recently bought the metabones speedbooster to match my old nikon lenses with my GH3 and it totally made a big difference. So if you do get the GH4 ...definitely invest on the speedboster. You'll be glad you did.

October 27, 2014 at 4:49PM


have shot lots of weddings with both gh4 and various canon cameras. they can be matched pretty easily in post, and I've not found that the gh4 holds me back too much in low light. get fast glass and problem solved
