Update 26 August 2021
Update: The C100 is now discontinued but it’s still a good used buy if you don’t need 4K.
The Canon C100 has a large sensor and takes interchangeable lenses, but it’s much better than a DSLR for filmmaking.
- Great image quality with excellent low light performance
- Takes high quality interchangeable lenses
- Much better handling and audio than an SLR and needs fewer accessories
- Bigger and heavier than mirrorless cameras
- Viewfinder on the original C100 is small and awkward to use
- No 4K
The Canon C100 was the most affordable camera in Canon’s Cinema EOS range. These interchangeable lens cameras combine many of the advantages of mirrorless cameras/DSLRs and professional camcorders. They’re a great choice for documentary and corporate video work, and low budget indie filmmakers.
Like a DSLR, the C100 has a large sensor and takes high quality lenses, but it’s designed for shooting video. So it has much better handling and audio, you’ll need fewer accessories, and it’s much quicker to set up and use.
Handling and audio
The C100 has a removable handgrip on the right, a detachable top handle for low angle shooting, a tilting LCD screen and an eye-level electronic viewfinder. You can access key controls quickly with customisable buttons on the camera body.
The top handle has XLR audio inputs and controls for using professional microphones.
Video is recorded from the whole of the 8MP CMOS sensor, so the shots are sharper and have much less moiré/aliasing than SLRs. It’s a lot easier to get good footage in low light: the base ISO (the setting that produces the best quality images) is a high 850. You can get usable footage up to around 20000 ISO (it goes up to 80000).
You can shoot in contrasty scenes without losing highlight detail by using Wide DR mode (usable straight out of the camera) or C-Log (which must be colour corrected afterwards).
Built-in neutral density filters (2, 4 and 6 stops) let you keep the shutter speed down and the aperture open when shooting in bright light. This is much more convenient than using add-on filters.
It can’t shoot 4, but the sharp 1080p footage looks better than the 4K you get from many other cameras.
The C100 has a Super 35 sensor, which is slightly larger than the APS-C sensor in many mirrorless cameras. So you can get good shallow focus effects. You can use EF-S lenses, which are smaller and less expensive than lenses for ‘full frame’ cameras.
The Mk I version records 1080p Full HD at 24, 25 or 30fps to AVCHD files at up to 24 Mb/s, Internally, it’s limited to 4:2:0 at 24Mb/s, but with an external recorder such as the Atomos Ninja or Blade you can export uncompressed ‘broadcast quality’ 4:2:2 video.
It can also shoot 60i/50i slow motion, but only in ‘interlaced’ (not ‘progressive’) mode, which isn’t as good.
Canon’s excellent Dual Pixel autofocus was a paid upgrade on the original C100. If fast AF is important, buy one which has had the upgrade, or get a C100 Mk II.
Should you buy the C100?
If you want excellent video quality with film-like depth of field and camcorder-like handling, the C100 is hard to beat.
The C100 is useful for drama as well as factual filmmaking. If you’re on a tight budget, having a camera with a good dynamic range, audio and low light performance means you can work faster and lighter.
If you’re looking to upgrade from a Canon APS-C camera, it may make sense to choose the C100 rather than a ‘full frame’ SLR like the 5D Mk III or IV. You’ll get better footage (though you won’t be able to shoot high quality stills), you’ll need fewer add-ons, and you’ll be able to use your EF-S lenses.
The C100 in use
Naom Kroll used the C100 to shoot his short The Mechanic in five hours. Here’s his article on why he used the C100.
StillMotion’s documentary Pulse makes great use of shallow focus and the C100’s wide dynamic range and low-light capability. There’s also a ‘making of’ film (made for Canon).
The first C100 wasn’t perfect. The AVCHD file format needs the right workflow to avoid losing quality when you import it into your editing program, the lack of progressive slow motion is limiting, and the electronic viewfinder was small and awkward to use. The more expensive MkII version doesn’t have these issues.
Lenses for the C100
The C100’s excellent low light performance means that you can get usable results with slower, less expensive lenses.
But constant aperture lenses are useful, to avoid exposure changes when you zoom.
The professional 24-105 F4 L L lens is popular with C100 users, though it doesn’t go very wide on the crop sensor.
The 17-55 f/2.8, designed for APS-C cameras, is faster and slightly less expensive.
The C100 Mk II
The MkII version of the camera has better handling and proper slow motion. Dual Pixel AF is included and it offers face tracking, the electronic viewfinder was much improved, and the LCD screen is better. It can also record in MP4 format at 35Mb/s: in theory that should make for better image quality than the original, but users say it’s hard to see much difference.
