Canon EOS 7D Mark ii vs 6D Comparison, what’s the difference?

A few days ago, Canon launched the EOS 7D Mark II at photokina. Like the previous model, which now goes back to 2009, it is a top-of-the-range reflex with APS-C sensor, made for professionals or advanced amateurs. Given the excellent technical specifications – and the fact that it’s just been launched -, the list price is important: $1799 for the camera alone. So, many have been asking if this type of model had been improved given the presence of Full Frame at a lower price, like the EOS 6D to stay in the Canon house. We’re ruling out of the evaluation the condition in which a user already had a Full Frame or APS-C camera, in case they want to deal with the choice to keep the investment made active, and we focus instead on comparing those two models as though it’s a first purchase.

Signal/noise ratio

The advantages of the 6D’s 35mm full frame sensor are obviously divided in two fundamental areas: a better output at high ISO and lesser DoF (depth of field) with the same focal length and aperture. In short, a Full Frame we had imagined to be cleaner with the same sensitivity and that has a greater “tridimensional effect”. In reality, this last factor may be considered for some uses to be an advantage, because on the APS-C we had the possibility of using the same aperture that we use on the Full Frame and have more focus area. It all depends on the result we want to achieve; however, it’s always about a difference between the two worlds. We say that if we usually take pictures with ISO superior to 3200 for necessity reasons, then the 6D has a first important advantage.

Operating speed and computing capacity

The 7D Mark II possesses a dual DIGIC 6 processor, surpassing even the 1D X that’s equipped with Dual DIGIC 5+. The 6D, on the contrary, possesses only one DIGIC 5+, exactly like the 70D. One of the advantages of all this processing power is an exceptional operating speed, but there’s also the burst that reaches the 10 fps against the 4.5fps of the 6D. Thanks to a decent buffer we are able to store as many as 1090 photos in sequence with the JPG format and 31 in RAW (the 7D stops at 94 JPG and 25 RAW). Moreover, the 6D has a maximum shutter speed of 1/4000, whereas the 7D Mark II reaches 1/8000.

Auto Focus

The Canon 6D has saved on the AF, including a form with only 11-point auto focus system which only has one central cross-type point. The 7D Mark II, on the contrary, has exceeded even the most expensive 5D Mark III and 1D X (61 points). In fact, there is a 65 points all cross-type AF system and a central point sensitive as far as f/8 to be used with lenses equipped with extender. Moreover, it inherited the ‘Intelligent Tracking and Recognition’ (iTR) technology directly from the EOS 1D-X. The other innovation of the 7D Mark II is the Dual Pixel CMOS AF, already seen in the 70D, which offers an autofocus in Live View much quicker and even the possibility to use the continuous focus in movie recording. On this aspect, the comparison with the 6D is won with no ifs or buts.

Body and Ergonomics

The 7D Mark II has a body virtually identical to that of the professional 5D Mark III. The step up from the Mark I is evident and is also improved by 4 times tropicalization second Canon. The 6D is smaller, which for some may be positive, but it is certainly less professional, ergonomic and balanced with heavy lenses. Also on the 7D Mark II the amount of physical controls is much higher and offers more convenience in changing the advanced parameters, such as the white balance or compensation (which in 6D not have direct access) and AF point (thanks to the joystick ).

Viewfinder and Display

The rear display is almost identical: 3" Clear View II TFT LCD with 1.040.000 points. It’s fixed in both devices and there’s no touchscreen, so on this aspect it’s possible to prefer the Canon 70D where it is articulated and sensitive to the touch. Regarding the viewfinder have on both a pentaprism, but in the 6D the coverage is of 97%, it is of 100% in the 7D Mark II, providing greater accuracy in the frame.


As well as the presence of the Dual Pixel CMOS AF that’s already been cited, that improves the speed and the efficiency of the focus on movies, the 7D Mark II possesses another advantage too in the video field, that is the possibility to record in FullHD at 50fps, the possibility that in the 6D the resolution goes down to only 720p. Moreover, the 7D Mark II has the video output HDMI exit not compressed to 8bit 4:2:2 and, for the first time, it enables the correction of the distortions of the lens even in the movie recording.


There is only one slot for the SD card in the Canon 6D, whereas in the 7D Mark II there were two: one Compact Flash and the other SD. As well as the possibility of using the most professional CF, there is the big advantage of being able to work in backup on both forms, an addition that will make many people happy and photographs given that the risk of losing one’s own work because of a memory break is limited. The USB connection in the 7D Mark II is of the 3.0 type, while it is a USB 2.0 type in the 6D.


The Canon 6D is equipped with Wi-Fi and GPS whereas there is only the GPS in the 7D Mark II. Thus, we are giving one point to the 6D for the greater fullest and the possibility of being controlled remotely by Smartphone or tablet.



Historically, Canon full frame cameras in the 6D series, don’t have built-in flashes. On the other hand, the 7D Mark II has a built-in flash and there is also the possibility to control other flash units wirelessly, which can be very useful since it does not require the additional purchase of a trigger.

Buying Guide:

The Canon 7D has been in the market for nearly five years. Many thought this model would not be upgraded since there are more economical full frames, such as the 6D, the Nikon D600 / D610 and also the Sony A7. If you consider a full frame camera as the next progression from an APS-C, then a full frame body at lower price would be a more attractive option than the Canon 7D Mark II.

However, the 7D Mark II essentially has the body of a 5D Mark III with an APS-C sensor, which makes it superior to a 6D in many respects. We have tried to list the most salient points of the two models, and each photographer will have their preference. For some individuals, high ISO sensitivity could be a key point, whereas for others, the motor-focus and burst may be of more importance. Certainly however, the 7D Mark II makes sense and its APS-C segment is much more professional than the full frame 6D. Nikon seems to think otherwise, because from what has been presented, their economic Full Frame models (D600, now D610) no longer have updated professional APS-C D300s which date back to 2009. Nikon’s line of APS-C ends with the D7100 model, which costs less than the D610. While a lineup is perhaps a more logical approach, it deprives us of a really professional APS-C body.

Canon 7D Mark II vs Canon EOS 6D, Which one to choose?

If we only compare the price of the 6D and the 7D2, many of us may not prefer the 7D ii because they have almost the same price and the 7D ii just is a cropped frame camera, it seems that only when cropped frame camera are cheaper than full-frame cameras is it reasonable, this opinion that nothing is taken into consideration except the sensor format is very ridiculous.

Let’s take a look at the parameters of the 7D2, a new 65-point all cross-type AF system. supporting low light focus of -3EV, with 7 kinds of built-in auto-focus modes, has an added AF Area Selection Lever to easily switch among different autofocus modes, which surrounds the Multi-Controller thumb-joystick, and for the first time in history, is equipped with an EOS iSA system which adopts 150,000 pixels of RGB+ infrared photometry sensor. This feature increases the success rate of focus tracking and accuracy of automatic selection of the AF focus, achieving a high-speed of 10 frames per second of continuous shooting. The APS-C frame sensor, equipped with 20.2 million effective pixels, supports 70D’s Dual Pixel CMOS AF. The magnesium and aluminum alloy body is also dust and splash resistant.

It is not difficult to find, the 7D ii is a highly specialized camera, especially for Eco photographers and those shooting sports subjects, the new 65-point all cross-type focus system, improved focus tracking algorithm and 1.6X telephoto advantage of an APS-C frame, are all designed for seeking "fast". It is a specialized and speedy SLR for specific photographers, but the picture quality is not its advantage.

For the average home users, the full frame of the Canon eos 6D brings the advantage of the image quality, but the 11-point auto focus system which only has one central cross-type point is the biggest weakness for users of shooting sports subjects, and the engineering plastics and the magnesium and aluminium alloy of the 6D is slightly worse in durability. The advantage of the Canon 6D lies in its lightweight body structure and built-in WiFi capabilities, the whole configuration is very user-friendly, and very suitable for users of light duty and slow shooting.

If the subjects you shoot are mainly dynamic, such as pets photography, outdoor nature photography and so on, then the 7D2 is your first choice. But it can not be compared with the 6D in picture quality and high sensitive performance.

Canon EOS 6D

If the subjects you shoot are mainly static, such as portraits, still lifes, travel, family photos and other subjects with no strong demands on focus, then the high picture quality and high sensitive performance brought by the full frame of the 6D will meet your needs, and using a large aperture lens on full frame camera will bring the really shallow depth of field effects, which will be more intense than the APS-C camera.
