Canon EOS 6D Mark II vs EOS 7D Mark II: Specs compared

Canon recently updated its most affordable full-frame DSLR camera in the shape of the EOS 6D Mark II

Full-frame is widely seen as the holy grail of DSLRs, but just how much are you getting when compared to Canon’s three-year-old flagship APS-C format DSLR camera, the EOS 7D Mark II?

Interestingly, both cameras are classed by Canon as enthusiast-level rather than professional. So, despite the difference in sensor size, we have put the two cameras up against each other to see which comes out on top. 

What advantage does each format bring? How has Canon’s DSLR camera technology moved on during the last three years? Read on to find out.

Canon EOS 6D Mark II vs Canon EOS 7D Mark II: Sensor and processor

  • Canon EOS 6D Mark II: 26.2MP full-frame CMOS sensor, ISO 100-40,000 (exp. 50-102,400); DIGIC 7 processor
  • Canon EOS 7D Mark II: 20.2MP APS-C CMOS sensor, ISO 100-16,000 (exp. 51,200); Dual DIGIC 6 processors

One of the clearest differences between the two cameras is in the image sensor department. 

The EOS 6D Mark II features a full-frame CMOS sensor and the EOS 7D Mark II an APS-C CMOS sensor, and the latter applies a 1.6x crop factor to mounted lenses. 

The EOS 6D Mark II features a new 26.2MP sensor, with image dimensions of 6240x4160 pixels. It’s not a huge leap from the 5472x3648 pixels in the EOS 7D Mark II, but the difference for higher resolution images is noticeable enough.

One of the main differences between these two bodies is that the EOS 6D Mark II uses a full-frame sensor while the EOS 7D Mark II uses an APS-C one

Despite its higher pixel count, the EOS 6D Mark II's larger sensor ensures each pixel is larger – and what we tend to find is that larger pixels usually make for better low-light performance and dynamic range.

In addition to higher resolution images and larger pixels is a greater ISO sensitivity range. The EOS 6D Mark II can shoot at ISO 100-40,000, and has expansion settings to ISO 50-102,400 equivalents, while the EOS 7D Mark II has a native range of ISO 100-16,000, which can be expanded up to ISO 51,200 equivalents. This gives the EOS 6D Mark II a 1.5EV native ISO range advantage. 

Forgetting the advantages for each sensor format, the EOS 6D Mark II comes out on top here, with a higher megapixel sensor, larger pixels and a greater ISO range.

In contrast to the DIGIC 7-toting EOS 6D Mark II, the older EOS 7D Mark II uses the previous DIGIC 6 engine – but it has two of them on board

In terms of processing power, the EOS 7D MK II packs two previous-generation DIGIC 6 processors, while the EOS 6D Mark II features a single DIGIC 7 processor. 

Canon EOS 6D Mark II vs Canon EOS 7D Mark II: Video

  • Canon EOS 6D Mark II: 1080p (Full HD) up to 60fps
  • Canon EOS 7D Mark II: 1080p (Full HD) up to 60fps

Video specs on both cameras are very similar. Both will shoot 1080p (Full HD) videos at frame rates up to 60fps, and neither offers slow-motion recording.

It may come as a surprise that the EOS 6D Mark II lacks 4K video recording. This is more understandable for the EOS 7D Mark II, which is three-years-old now, but many would expect to see this on a camera released in 2017.

Despite being newer and pricier, the EOS 6D Mark II (pictured above) lacks the EOS 7D Mark II's headphone port, although both have microphones sockets

One thing it does have, however, is digital five-axis image stabilisation, something the EOS 7D Mark II lacks. Both systems do, however, work with the optical image stabilisation systems found inside many of the company's lenses.

Interface wise, both have a 3.5mm microphone socket and HDMI output, but the EOS 7D Mark II is the only one to feature a headphone jack.

Canon EOS 6D Mark II vs Canon EOS 7D Mark II: Burst shooting

  • Canon EOS 6D Mark II: 6.5fps
  • Canon EOS 7D Mark II: 10fps

The EOS 7D Mark II's continuous shooting mode is noticeably superior to that of the EOS 6D Mark II. 

It can shoot up to 10fps for an infinite number of JPEGs or 31 Raw images, while the EOS 6D MK II can manage 6.5fps for up to 150 JPEGs or 21 Raw images. So, here, the EOS 7D Mark II is very much the victor.

It should come as little surprise that the EOS 7D Mark II (pictured above) boasts a faster frame rate than the EOS 6D Mark II

Canon EOS 6D Mark II vs Canon EOS 7D Mark II: Autofocus

  • Canon EOS 6D Mark II: 45 all-cross-type AF points and Dual Pixel CMOS AF
  • Canon EOS 7D Mark II: 65 all-cross-type AF points and Dual Pixel CMOS AF

Autofocusing appears to be very similar between the two. 

The EOS 7D Mark II features a 65 cross-type AF points spread over a wide area, while the EOS 6D Mark II has 45 cross-type points more concentrated in the centre of the frame. 

The EOS 7D Mark II's system has a dual-cross-type centre point sensitive to f/2.8, which remains cross-type to f/8, while the EOS 6D Mark II's centre point is f/2.8 sensitive as standard and dual cross-type to f/5.6. 

Designed for action, the EOS 7D Mark II sports a 65-point, all-cross-type AF system

Both systems give an AF working range of EV -3 to 18, which is usable in conditions as dim as moonlight. 

Both also feature Canon’s Dual Pixel CMOS AF, an on-sensor phase-detection autofocus that promises smooth focus during video and when using live view.

While similar, the EOS 7D Mark II appears to have the AF edge.
