At first glance, the A7 III vs 6D Mark II comparison looks simple. The Canon EOS 6D Mark II is a DSLR camera, while the Sony A7 III is a mirrorless model.
But you can’t simply rely on the design to properly compare two high-end, smartly-priced cameras like these. Both cameras offer a host of excellent features, and they’ll both give you amazing image quality.
The Sony A7 III works faster and has the ability to record 4K video, giving it nice advantages over the Canon 6Dii. But if you already own a lot of Canon EF lenses, is it worth your money to switch?
Here are the Steve’s Digicams quick thoughts on these two cameras.
- Sony A7 III: Sony may have mislabeled the A7 III as its “basic” camera in the A7 family. This model offers 4K HDR video, 15 stops of dynamic range, a full frame image sensor, fast burst shooting modes and a reasonable price point versus its fellow A7 models.
- Canon EOS 6D Mark II: The 6Dii excels in landscape, wildlife, portrait, and wedding still images, delivering an excellent mix of accuracy and convenience. It has a nice price point for a full frame image sensor too, but we wish it had 4K video capabilities.

A7 III vs 6D Mark II: KEY DIFFERENCES
Here are the primary differences between the Sony A7 III and the Canon EOS 6D Mark II.
- 4K Video Resolution: One of the biggest advantages of the Sony A7 III over this Canon DSLR is the A7 III’s ability to record video at a 4K resolution. The EOS 6D Mark II is limited to full HD 1080/60p recording.
- Burst Mode: The Sony A7 III has a larger memory buffer, allowing it to record more photos in burst mode than the 6D Mark II. The A7 III also operates faster in both JPEG and RAW modes.
- Displays: While both have touchscreens, the 6D Mark II offers a much more user-friendly touch-interface as well as a vari-angle display that can forward, making it ideal for vlogging style videos.
- DSLR Versus Mirrorless: The Canon 6Dii is a DSLR style camera, while the A7 III is a mirrorless design, allowing it to be smaller and lighter.
- Dual Memory Card Slots: While the A7 III boasts dual memory card slots, the 6D Mark II only has one, putting it at a disadvantage for anyone who likes to backup media as they shoot.
- Image Stabilization: You’ll receive 5-axis in-camera image stabilization from the Sony A7 III, which improves lowlight still image capture and smooths hand-held video.
- Top-Panel Screen: It’s easier to make changes to the Canon 6D Mark II’s settings because of its display screen on the top panel.
A7 III vs 6D Mark II: WHICH ONE DO YOU NEED?
If your primary focus (get it?) is still photography, the Canon 6D Mark II is a terrific upgrade into the world of full frame image sensor cameras — it takes gorgeous photos! But, in terms of overall performance and features and capabilities, the Sony A7 III is the clear winner for anyone not heavily invested in Canon glass. To put it another way, if you want a camera that will shoot video as well as it captures still images, the A7 III is a better option and a far more professional multi-media camera. That said, shooting and editing in 4K requires a lot more storage and processing power, so sticking with HD for digital content creation isn’t a deal killer at all (and there are a ton of prominent YouTubers using this camera just for that).
