Canon EOS Rebel T7i vs EOS 77D vs EOS 80D, what’s the difference?

When the entry-level EOS Rebel was rolled out into the market by Canon some years back, launched simultaneously with it was the Rebel T61. Basically, both have a striking resemblance and more or less showcase the same set of features. In terms of body-mounted controls, the T6s definitely had more to offer, as well as a small LCD display which has been designed to appeal to users with more experience, who require having more control. 

Fast track to just two years and canon is at it again, with the roll out of the EOS Rebel T7i, as well as the 77D which will comfortably rank among the company’s best entry-level camera. (More information about T7I and 77D, please read this article)

To make things a bit clear and ensure that Canon’s model numbering is well understood, the EOS T6i will be replaced by the EOS T7i, whereas in canon’s enthusiast EOS DSLR range, the successor of the T6s is the EOS 77D and ranks just a little below EOS 80D.

Let’s quickly dive into some details and observe how well the figures for these cameras compare.

The difference between Rebel T7i and EOS 77D:

The T7i is actually the simplified version of the 77D, end the functions that the T6s has but the T6i does not have include (Very similar to the difference between T6i vs T6s):

  • Top info LCD
  • Quick control dial on rear
  • Multi-function Lock Switch
  • Auto Display-Off Sensor by the viewfinder
  • AF On button

The T7i is $150 cheaper than the 77D in listing price. Because the top info LCD and Quick Control dial will completely change our habit of shooting, I think in situations where the buyer is not terribly price sensitive, we should select the enhanced version of the 77D instead of the T7i.

The following I will compare the T7i/77d and EOS 80D in detail:

Sensor and Processor

T7i and 77D pairs the same 24MP APS-C sensor with EOS 80D but has a faster DIGIC 7 processor

The EOS 77D and the EOS T7i use the same basic sensor technology that is seen in the Canon EOS 80D. The difference, however, is that their 24.2 million pixel APS-C CMOS sensors are combined with the latest DIGIC 7 image processor of Canon. This combination definitely ensures that the performance-speed, and image-quality are immensely enhanced.

DIGIC 7 image processor

In the aspect of ISO sensitivity, with the EOS T6i, the sensitivity range is limited to 100-12,800 (expandable to ISO 25,600). However, the EOS T7i and EOS 77D are now capable of shots between ISO 100-25,600 and, additionally, expandable to as much as ISO 51,200. The higher end of EOS 80D have a rating between 100-16,000 (expandable to ISO 25,600). In my opinion, I believe the more improved ISO range of 77D may not actually greatly enhance the noise handling or result in a huge difference. There is a likelihood that the 77D and the 80D use the same sensor which would make the raw files the same. Higher ISO numbers on the 77D are more likely to offer improved noise processing JPGs that are offered by the new Digic 7 processor. Speculation aside, we should assume that the new camera does, in fact, gain a slight advantage.

Autofocus

The Canon 77D, just like the 80D, has an Anti-Flicker option which can detect the faint flicker of artificial lighting and adjust accordingly for the timing of shots with burst inclusive. This helps get rid of light level fluctuations, as well as color cast, during course of a given sequence shots.

45-point AF module

The 45-point-all-cross-type AF system from the EOS 80D that’s been handed down to both cameras, further improves their autofocus. Although Canon’s higher-end models have more AF point configurations than both cameras, but the 77D allows for zone AF with nine zones, large zone AF mode in three groups and single AF point selection. There’s also a fully automatic mode that allows the camera make an automatic selection of an appropriate point from the full 45 available points. There are 45 AF points available, out of which 27 are f/8 compatible with a sensitive centre point, down to f/2.8. When there’s a low light, the AF system can acquire as much focus as the EOS 80D because it has a -3EV-18EV working range.

In addition, a metering sensor with 7,560-pixel RGB + IR is obtainable in the 77D just like the 80D. Skin tone and colour detection for an improved facial recognition and subject tracking is provided by the 77D as its metering sensor that works in conjunction with the Al servo AF II autofocusing system.

As with the 80D, the Rebel 77D’s capacitive touchscreen allows for Touch Focus during both Live View still photography and before/during video recording. Just tap your finger on the LCD where you want the camera to focus and it happens – smoothly. Touch Focus is very simple and effective.

There’s a capacitive touchscreen in the Rebel 77D just like that of the 80D. This touchscreen makes touch focus possible when you have an ongoing Live View still photography or before and during video recording. Your camera focuses where you want it to with just a finger tap on the LCD. The touch focus is very simple and effective.

Speed

Continuous shooting speed

Talking about still image performance metrics, what the new canon 77D has to offer in terms of continuous shooting rates compared to the higher-end 80D is a bit similar, if not slightly slower. With traditional viewfinder (non-Live view), speed reaches 6fps in high speed continuous mode, the 77D just happens to be a fraction slower than the 7fps which the 80D claims to possess (our review reveals that the 80D, at 6.8fps, just falls short of spec). 6fps, although not the fastest, should still perform quite well in the capturing of very short moments for all-purpose sports, as well as a wide range of moving objects. For times when you don’t need to capture moving objects, the camera also offers 3fps continuous mode.

Shutter lag

Shutter lag happens to be another specification that insures that you capture an image at the precise and exact instance you’ve chosen, such as when a baby’s face brightens up and looks at the camera with sparkling eyes. It has been showing improvement continuously in the rebel line even though it was lacking initially. Rebel shutter lag lightens up very fast compared to other types of cameras. The shutter lag spec of the 77D’s, at 70ms, is quite impressive. However, it still possesses a shutter lag of about 10ms with 80D, an almost negligible difference. But photographers who are more experienced may find the Canon 80D to be more responsive.

Shutter speed

The range of shutter speed, however, is a bit different than what the 80d has to offer, with the 77d reaching 1/4000s for its fastest shutter speed, whereas the 80d seemed faster at 1/8000s. in terms of regular usage, this may not really pose a big setback, but if you love to take shots in bright environment, making use of fast-aperture lenses, you could find yourself needing much more shutter speed so as to get a well exposed shot. The 77D, on the slow end, permits a bulb mode and a 30-second exposure, just as it is obtainable in the 80D. Maximum flash sync stands at1/200s, while the flash sync speed on offer by the 80d stands firm at 1/250s.

Buffering system

Better than EOS 80D. But significance is questionable

According to Canon’s specs, you can continuously shoot 27 raw files or JPEGs until you fill up the card (must be UHS-I SD card) at up to 6fps with the 77D or T7i. Compared to the T6i and T6s that usually sustain a burst of up to 8 raw files or 940 JPEGs at 5fps, the 77D is far advanced. JPEG buffer capacity with a UHS-I card is placed at 110 frames for the 80D. The significance is questionable because it is rare for a photographer to shoot more than 20 shots in a row (At least I am), much less 110;

The 77D gives a maximum of 23 or 27 frames with RAW + JPEG or RAW – only while 22 or 25 frames are obtainable with 80D. There’s not much of a difference; what’s really important, for action photographers especially, is the shooting speed. The 77D has its shooting speed at 6 fps while the 80D’s at 7fps; the faster speed of the 80D provides it with more time to get the buffer cleared.

Screen:

As on the EOS 80D, the Canon 77D has a 3.0 inch vari-angle Clear View LCD II touch screen with a screen resolution of 1,040,000 dots. It would have been a great idea to enhance the resolution, though this is presently one of the most polished touch interfaces, so upgrading it might be unnecessary to Canon.

Video

You have nothing less than a top class video quality with the highly developed DSLR video; more so when a Dual pixel CMOS AF is in use. The 77D shares many similarities with the 80D. A 4k video recording capabilities is however absent in Canon’s EOS 77D. Its highest limit is 1080/60p, regardless of the fact that it has a faster DIGIC 7 image processor.

The 80D beats the 77D in terms of video file formats. There are limitations to the video file formats in 77D: MP4 is its primary video format and its only compression setting is IPB. You can only get a MOV ALL-1 video when the 77D is set in a 1080/30p Time Lapse Movie mode. Only IPB compression is available for 1080/60p and other video recording formats. The time limit for when the 77D is set for a continuous video recording, regardless of any resolution or frame rate, is just 29 minutes, 59 seconds. Immediately the recording gets to this point, it automatically stops and is manually restarted.

Viewfinder

The viewfinder of the canon 77D resembles the T6’s smaller pentamirror type: has an eye-sensor, a 95% coverage, ~0.82× magnification and ~19mm eyepoint. There is no eye sensor in the 80D although it has a 22mm eyepoint, ~0.95x magnification and a ~100% coverage that comes with a larger and brighter pentaprism viewfinder.

Compared to pentamirror version, the pentaprism viewfinder displays brighter images but when it comes to image formation, there’s pretty nothing much that viewfinder can do. Those that use manual focusing might benefit from brighter viewfinder but autofocusing has no need for it.

Design

There’s really nothing new in terms of features, or anything different in the exterior appearance of the new Canon 77D. Those familiar with EOS DSLRs will know this very well. The DSLR aesthetic and control layout of the 77D follows the traditional pattern of Canon’s models. The overall appearance is much more similar to T6s; although there are some features in the bigger 80D model that’s also present in the 77D. The 77D weighs 1.2 pounds and is 3.9 by 5.2 by 3.0 inches(HWD) when measured. The 80D which is 1.6 pounds weighs more than the 77D partly because of a lighter pentamirror viewfinder. The world is brighter and slightly larger when viewed with the 80D because of its pentaprism.

The top deck of the 77D is very similar to that of the earlier Canon T6s: the handgrip has a slightly boxier shape, and a number of controls are found on top. The top information display in 77D is similar to that of higher-end EOS cameras and the unique Rebel T6s; while the 80D’s top information display is larger than that of the 77D, the 77D’s is larger than the T6s. A rear AF-ON button that you won’t find in the Rebel models has been included in the 77D; this is an advantage to those who wants to better control their autofocus operation.

Quick access to wireless connectivity setting and camera-smart device pairing is now available in 77D due to the newly added shortcut button for Wi-Fi connection.

http://thedigitalcamera.net/wp-content/uploads/2017/02/Guide-Mode.jpg

The Guide Mode for beginners is turned off by default in 77D. It uses different photographic situations to guide beginners just like the new T7i. Also available is group photo mode; with this, there’s focus on everyone in a group as the group photo mode sets the f-stop using face detection. EOS D80 doesn’t has the Guide Mode.

Other features

An anti-flicker option is included in the canon 77D — also present in the 80D and 7D Mark 11. This detects any slightest flicker of artificial lighting sources and reacts by adjusting the timing of shots and bursts. Unstable light levels and colour casts that occur during series of shots are are eradicates by this anti-flicker option.

Conclusion: Which Should You Buy?

The 77D is ranked mid-level, as an upgrade on cameras of the rebel series yet remain ranked below EOS 80D by Canon, targeting some serious but non-professional photographers. While it seems obvious that Canon spell the difference between this model and the rebels, it is still basically a rebel in mind. It shares the same shape as well as same features with rebel T71 that was announced at the same time with it. If the price tag is not a turn-off, most photographers are more likely to go for this camera than t7i, based on the fact that the few unique features it has are valuable ones.

Is it worth to upgrade 77d from T6i or T6s? Yes. The two new AF systems– 45 points traditional phase detection system and Dual pixel AF system is a great upgrade for the 77D compared to the Rebel T6s. There are also pleasant improvements like a RAW image buffer depth that’s been greatly increased and a faster frame rate from 5fps of T6i/T6s to 7fps. But I suggest more consideration EOS D80 if it has a discount.

As a more high end choice which can satisfy most shooting purposes, the Canon 80D is still the better camera that can attract most people. My personal advice is to purchase the cheapest camera available that suits you, and then pair it with the best lenses you can afford. If you use the rebates currently available, you can buy the Canon 80D with the 18-135mm STM lens (what I would personally recommend), for the same price as the 77D with that same lens.
