Deciding on what new camera to buy

I just sold my GH4 and trust me, It was really really good but it was time for me to switch to a full frame. Is the Canon 5d worth buying for film making?


The full frame camera to buy for video work is the Sony A7S camera, it has professional image controls ( like the GH4 ), it records with a good range of CODECs, and it's the best camera on the market for low light work.

Interesting. The problem is I also have alot of Canon lens.

You can buy adapters to mount your Canon EF lenses on the Sony A7S camera for about $100

Metabones vs Commlite Canon Lens to Sony Body Adapter

Pretty much any lens can fit any camera, if you are willing to potentially drop the auto stuff. I still can't figure out how my Canon EF-M lenses get their butts kicked by the 55mm Super Takumar and even the venerable 58mm Helios 44 both on an £8 M42 adapter.. I see all those Nikon F mount primes on ebay. It's silica porn.

Sony A7S plus Metabones Speed Booster

Rumor has it that the speedbooster isn't a good adapter for the A7s.
Probably because the A7s is fullframe itself.

Everyone seems to be going for the A7s, the 5D still has a great look and is very reliable - but the A7s image is hailed as superior by most.

A7s has far superior low light.
i have the 6D which is equivalent to the 5D but much cheaper. if you go for 5D i would recommend 6D instead. but the A7s seems to be a better camera (i have no experience with it however)

I have the 6D too. It's great for photos, but for video, you'll need to watch out for aliasing and moire, which can be pretty bad. OK if you're doing narrative work, where you can control what's on camera; but for documentary/event kind of work, you will run into problems at wide angles.

I am also looking to get a new DSLR camera and I am torn between the Samsun NX1 and the Sony A7s. I am leaning more towards the Samsung NX1 because the specs on the NX1 are amazing. The only advantage that the A7s has over the NX1 is that it is great on low-light situations and It is much smaller, thinner and lighter than the NX1.
Here's a comparison:
I would be using the camera primarily for video. Any suggestions?

How does the a7s compare to the 5d mark iii in terms of stills?

May 15, 2015 at 12:29PM


The 5D Mk3 has almost double the still photo resolution of the Sony A7S, so if you like larger prints or like to be able to crop your images a fair bit the 5D Mk3 would be the better camera for still photos.

If still photos was important and you still wanted something fairly good for video work, the Nikon D750 or D810 are two other cameras to consider. Both are full frame cameras, and both do a decent job with shooting video.

I sold my old 5d3 for a GH4. You'd just be going backwards. Not sure why you would need to switch to full frame though, unless you were really having trouble achieving shallow depth of field with your GH4.

Sorry, but I find it hard to take your question serious. Going back from a GH4 to a Canon 5D sounds rather silly. You can achieve a full-frame effect on a GH4 by using a speedbooster with fast lenses. Read Dave Dugdale's article here:

The Canon 5d mk iii is still the only Full Frame camera that can shoot 14 bit RAW video outside of The RED WEAPON and the ALEXA 65. SO if color rendition is his top priority as a filmmaker, the 5D isn't as silly of a choice as you may think it is.

There's a great video of Rodrigo Prieto talking about why he shot 12 bit 2K over 10 bit 4K for a project, saying that color rendition took precedent over resolution. So it depends on what you need from the camera. Prieto has always been very focused on color(look at "25th Hour"), and so perhaps this may be the case with the OP.

Not only that but if you would have read his other replies he's also using the camera for stills, and the 5D has the GH4 beat in that department. So it sounds like the 5D just may very well be the camera for him.

Going to have to agree with the people here saying that going from a GH4 to a 5D would be a significant step backward. The GH4 can't get to true full frame range, but the look it achieves with a speed booster and fast, slightly wider lenses is very close with much better image quality.

If real full-frame is truly what you need, though, the Sony A7S is a good call. I've used both the A7S and Gh4 and I prefer the Gh4 because the A7S doesn't have internal 4k and I find the colors require more work to grade well, but the A7S is still a great camera. Its low-light and dynamic range are phenomenal. You can always get 4k out of it with an external Shogun recorder.

I think Albert hit the nail on the head some people think 4k must be better because it's a higher resolution so they run out and buy a GH4 and wonder why it looks so terrible even though it's sharp. Sure you can buy a speedboster but with magic lantern 14 bit RAW is going to allow you to get a much more filmic look, and allow you to have more control over your image -In that sense the 5d mkiii is a step in the right direction. It also takes great stills.

I don't know whether shooting RAW on a 5Dmk3 involves the lineskipping all Canon DSLRs use to capture an image from the CMOS, but if it does it will be RAW but relatively soft image, because the amount of read horizontal lines is closer to 800 than to 1080. Not to mention the aliasing and moire this proces will generate sometimes (If it uses downscaling it will be looking a lot better.)
In that aspect you'll get a sharper image from a A7s.
Although the A7s has equal or even a bit more rolling shutter in full frame mode than a 5D.

And do you need to shoot RAW?
It has consequences for the whole workflow.
Or is using a Shogun or Odessey 7Q+ enough to get better (422 10 bit) gradable footage?

The A7s has some strange things like a rec button on a weird spot or the work around needed to 'quickly' do a custom white balance.
But you can switch to ASC-P crop if you want.

Make sure to test both cameras.
That is maybe the only real way to make an educated decision about what YOU need.
