Canon EOS Rebel T6i / EOS 750D

The EOS Rebel T6i (known as the EOS 750D outside the US) was until only recently Canon's key entry-level DSLR, taking the fight to the likes of the Nikon D3300 and D5600

The Rebel T6i / 750D was launched back in early 2015 and Canon has just announced an update – the Canon EOS Rebel T7i (EOS 800D outside the US).

Announced at the same time was the EOS Rebel T6s (EOS 760D), which is virtually identical under the skin to the Rebel T6i, but with a few more features designed to tempt slightly more experienced users.

Features

  • APS-C CMOS sensor, 24MP
  • 3.0-inch, vari-angle touchscreen, 1,040,000 dots
  • 1080p video capture

Despite the step up from the 18 million pixels in the Rebel T5i / 700D, the Rebel T6i keeps the older sensor’s native sensitivity range of ISO100-12,800. There’s also an expansion setting of ISO25,600 for very low light conditions. In movie shooting the maximum native setting is ISO6400 and there’s an expansion value of ISO12,800.

In a first for Canon DSLRs, the Rebel T6i features both Wi-Fi and NFC (Near Field Communication) technology to enable it to be connected to a smartphone or tablet for remote control and image sharing. It’s even possible to connect two cameras just by touching the NFC logos together, and then transfer images wirelessly.

Like the older Rebel T5i, the Rebel T6i has a 3.0-inch 1,040,000-dot Clear View II TFT screen that’s touch-sensitive. It also has an aspect ratio of 3:2 to match the uncropped ratio of the imaging sensor, while the vari-angle hinge on the side of the body means it can be placed in a range of positions.

There’s a 19-point phase-detect AF system when shooting through the viewfinder. The choice of AF point can be left to the camera to decide in 19-point AF mode, or it can be set manually in Single point AF or Zone AF mode. In Zone AF mode you have the choice of five groups of points for selection, whereas in Single point mode all 19 points are available for individual selection.

Canon’s Hybrid CMOS AF III system (with Face detection, Tracking AF, FlexiZone-Multi and FlexiZone-Single modes) is available with the Rebel T6i / 750D when using Live View. This is an improved version of the Hybrid CMOS AF II system found in the Canon EOS SL1 / 100D, having a greater number of focusing pixels arranged in a more regular array than in the past. Canon says it’s about 4x faster than version II and two generations ahead of the original Hybrid CMOS AF system in the Rebel T5i.

Unlike the Rebel T6s / 760D, the Rebel T6i / 750D doesn’t have a Servo autofocus option in Live View mode so there isn’t an option for focus to adjust continuously while the shutter release is held down and subject distance changes. There is, however, a Continuous AF option in the Live View section of the main menu. When this is activated focus is adjusted fairly slowly when the shutter release isn’t pressed. It’s designed for use in video mode and to pre-focus when shooting stills.

Build and handling

  • Aluminium alloy and polycarbonate construction
  • Design little changed from the EOS Rebel T5i / EOS 700D
  • 555g

The Rebel T6i / 750D’s aluminium alloy and polycarbonate resin with glass fibre chassis gives it a pretty durable feel for entry-level DSLR. Reassuringly, it doesn’t creak when it’s gripped tightly.

Textured coatings on the deep grip on the front and the small thumb bridge on the back help to make the camera feel comfortable and safe in your grasp.

Following the design of other Canon DSLRs, the Rebel T6i / 750D has a Quick menu that is accessed by pressing the Q button. This gives a quick route to some key features for adjustment. Setting adjustments can be made using the physical buttons and dials or by touching the screen. If you’re not used to using a touch-screen camera you may find that you start out using the buttons and dials, but gradually you start using the touchscreen because it’s so intuitive.

Being a DSLR, the Rebel T6i / 750D has an optical viewfinder. Canon has used a pentamirror design rather than the pentaprism versions found in more expensive cameras like the EOS 70D. This shows approximately 95% of the scene (the 70D’s covers 98%) so you may need to take care with composition to avoid including unseen elements around the edges of the frame.

As the screen is on an articulating joint it can be seen from a wide range of angles. Reflections are an issue in very bright light, but it is usually possible to see enough detail to compose images. In Live View mode it’s especially helpful to use the screen to set the AF point, or even set the AF point and trip the shutter when composing images at very awkward angles. 

The viewfiner uses a 'pentamirror' design that offers 95% coverage.

Perhaps the biggest handling difference between the T6i and T6s is that the T6s has a Quick Control dial around the navigation buttons. The T6i relies on an exposure compensation button instead. In manual exposure mode this button needs to be pressed while rotating the dial near the shutter release to set aperture, in the semi automatic modes it’s used with the dial to adjust exposure compensation. It’s a quick and easy task, but the Quick Control dial on the T6s / 760D makes these adjustments a little faster.

The exposure mode is set using the dedicated dial on the right of the T6i’s top-plate – this is on the left on the T6s. Unlike the T6s there’s no lock on the dial, but it doesn’t get knocked out of position easily and it provides a route to the same same exposure modes including program, shutter priority, aperture priority and manual as well as options such as Full Automatic (Scene Intelligent Auto), Creative Auto (which allows you to take control with simple instructions using non-photographic terms) and a collection of user-selectable scene modes, including some within Special Scene (SCN) mode.

Autofocus

  • 19-point AF, all cross-type AF points
  • Predictive AF
  • AF working range down to -0.5EV

Pressing the AF Area selection button once allows the navigation buttons to be used to set the desired AF point. Pressing it multiple times toggles through the AF-point selection modes (Single-point AF, Zone AF and 19-Point automatic selection AF). There’s also an AF point selection button to the right of the thumb rest on the back of the camera, but this doesn’t allow you to toggle through the selection modes. It would be nice to be able to set the AF point on the screen while composing images in the viewfinder as you can with some Panasonic cameras and the Nikon D5500.

The phase detection AF system that’s available when composing images in the viewfinder is fast and accurate, even in quite low light with the kit lens mounted. It means it’s a much better choice when shooting sport or action. In 19-point mode it does a pretty good job of identifying the subject, but Zone-AF and Single-point mode are a better choice provided you can keep the active area over the right part of the scene.

When using Live View mode I found the T6i / 750D is capable of getting subjects sharp quickly, so it’s possible to compose images on the main screen when hand-holding the camera. However, it’s not really fast enough to use it to shoot moving subjects, and there’s no servo option, so it can’t adjust focus as subject distance changes when your finger is on the shutter release.

Performance

  • 5fps burst shooting
  • Exposure weighted towards active AF point
  • 440 shot battery life

The Rebel T6i / 750D can also shoot continuously at up to 5fps. This may not seem fantastic by current standards, but it’s still very useful when shooting sport. Plus, the burst depth has been increased from the 30 JPEG or 6 raw files of the Rebel T5i / 700D to a whopping 940 Large/Fine JPEGs or 8 raw files.

A dedicated 7,560-pixel RGB and Infra Red (IR) sensor is provided for measuring exposure when the viewfinder is in use. As with the T5i’s iFCL metering system, these pixels are grouped into 63 segments (9×7) with the usual options of Evaluative, Centre-weighted, Partial and Spot metering. However, the partial (6.0% of viewfinder) and Spot (3.5% of viewfinder) coverage is a little more precise than in the T5i / 700D (9% and 4% respectively) and pixels on the sensor each have their own RGB-IR filter and are read independently. 

This is a similar system to the one in the excellent EOS 7D Mark II and Canon claims it’s more accurate than the T5i’s with improved colour detection. However, it’s worth remembering that even in Evaluative mode the metering is linked to the AF points, so the brightness of the subject could have an impact upon overall exposure.

Image quality

  • ISO100-12,800, expandable to 100-25,600
  • Huge jump in image quality from the T5i / 700D
  • Pleasing skin tones

The level of detail in images is a huge leap up from that from the T5i / 700D, but noise levels are about the same despite the extra 6 million pixels on the sensor.

Viewed at 100% on-screen, the T6i / 750D’s high sensitivity JPEGs look softer than simultaneously captured raw files, but even at ISO12,800 some look good at around A3 size (16 x 12 inches). 

As usual, when all noise reduction is turned off the raw files have more visible noise at 100%, but it’s fine grained and there’s no banding, so it’s possible to produce images that have a bit more ‘bite’ than the JPEGs.

Chroma noise only really becomes obvious at 100% in raw files captured at ISO1600 and above (when all noise reduction is turned off). Meanwhile the softening of detail that tends to go hand-in-hand with noise reduction in the default settings becomes apparent at 100% in JPEGs captured at ISO3200, though it’s not really an issue until ISO12,800.

EOS 750D vs EOS 800D: 14 key differences

With the arrival of Canon’s new EOS Rebel T7i (known as the EOS 800D outside the US), how do the two DSLRs compare? In a nutshell, the EOS Rebel T7i shares much the same intentions as the T6i, and soldiers on with much of the same tech, Canon has made a number of changes across the spec sheet to make it more appealing to the first-time user – some of which were first included inside more premium EOS models. So if you're undecided whether to hold off and wait for the EOS 800D or not, this will help.

1. Latest DIGIC 7 processor

While the EOS Rebel T6i / EOS 750D employed Canon’s DIGIC 6 processing engine, the latest EOS Rebel T7i / EOS 800D welcomes the newer DIGIC 7 version. This first surfaced inside the PowerShot G7 X Mark II model released last year before being included inside the more recent EOS M5 and PowerShot G9 X II.

Compared with previous engines, this is said to provide superior image processing and faster operation, and it also helps to boost burst speeds (more on this later).

2. Revised sensor

With the same 24.2MP pixel count as the EOS Rebel T6i, the sensor inside the EOS Rebel T7i appears to be unchanged at first glance. The spec sheet, however, reveals it to have a different total pixel count of 25.80MP (vs 24.7MP).This is the same total pixel count as the sensor inside the EOS 80D, which was newly developed for that model. Canon claims the two share the same technology here, so we should expect to see an improvement over the previous 24.2MP version.

3. Expanded ISO range

No doubt a consequence of the revised processor and sensor partnership, the new model features a slightly broader ISO range than before. Where the EOS Rebel T6i could be adjusted over a range of ISO100-12,800 as standard, the new model adds a stop at the latter end to create a native range of ISO 100-25,600.

Similarly, the expanded sensitivity option at the higher end of the scale has now changed from a setting equivalent to ISO25,600 on the EOS Rebel T6i to one equivalent to ISO51,200 on the EOS Rebel T7i.

A more minor change is that, when capturing stills, the entire ISO100-25,600 native range can now be accessed when the camera is set to the Auto ISO setting; previously this was limited to ISO100-6400. When shooting videos, this contracts to an ISO100-12,800 range.

4. New 18-55mm kit lens

Both the EOS Rebel T7i / EOS 800D and EOS 77D are released alongside a new EF-S 18-55mm f/4-5.6 IS STM kit lens, which Canon claims is the smallest non-retractable DSLR kit lens of its focal range.

Weighing 215g, the lens incorporates a four-stop Image Stabilizer to help maintain sharpness in images, as well as Canon’s STM technology, which promises discreet performance when capturing movies.

Some may notice, and be concerned by, the maximum aperture at the wide-angle end. Where this is typically f/3.5 on most kit lenses, this has been reduced by two-thirds of a stop, to f/4.

5. Revised AF system

The EOS Rebel T6i and its EOS Rebel T6s / EOS 760D sibling shared a 19-point, all-cross-type AF system that featured a single f/2.8-sensitive point in its centre. This was a perfectly sound performer, although the EOS Rebel T6i / EOS 800D packs something much more advanced.First, the array has been expanded to offer the same 45-point coverage as the EOS 80D, with all of these capable of cross-type performance. 27 points remain operational when using a lens with a maximum aperture of f/8, with nine of these staying cross-type.

Canon has also made a significant improvement to the camera’s sensitivity. Where the working range of the T6i’s system went as low as -0.5EV, this has dropped to -3EV on the T7i. In practice this should make the camera much more sensitive to details in low light, closer to the performance of more advanced models.

Canon also claims the camera offers the world’s fastest live-view autofocus system, with a speeds of just 0.03 sec. As is always the case with these claims, this relates to specific conditions and equipment: here, it relates to APS-C-equipped cameras that have phase-detect pixels on their sensors, and was determined when using the new EF-S 18-55mm f/4-5.6 IS STM at its 55mm setting.

6. More white balance options

You can now opt to shoot with the Auto White Balance set to other Ambience Priority or White Priority, depending on how much of the warmth in the scene you want to retain. Canon has already incorporated this feature inside other recent models, so its inclusion here is somewhat expected.

It’s also now possible to set the colour temperature across the Kelvin scale, something that T6i didn't offer.

7. Faster flash sync speed

Flash sync speed has increased from the EOS Rebel T6i / EOS 750D’s 1/200 sec limit to 1/250 sec on the newer model. Canon has also added a stop to the flash exposure compensation range, taking the previous -/+2EV range up to -/+3EV on the EOS Rebel T7i / EOS 800D.

8. Diffraction correction added to lens correction

When using lenses whose characteristics were known by the camera, the EOS Rebel T6i allowed for correction of distortion, peripheral illumination and chromatic aberration to be enabled and disabled as required. Now, on the T7i these have been joined by an option that aims to rectify the softening effects of diffraction.

These effects tend to be more prominent when shooting at smaller apertures, so it may interest those intending to use the camera for landscapes and other small-aperture applications. Incidentally, this isn't the first time we’ve seen this feature; it was included in other recent models such as the EOS 5D Mark IV and EOS-1D X Mark II.

9. Raw image processing

The T7i allows for raw images to be processed in camera after capture, something that wasn't possible on the T6i. Controls on offer include adjustment over exposure, white balance and noise reduction

10. Burst speed boosted

Whereas the Rebel T6i / 750D was capable of firing at approximately 5fps for up to 8 raw frames or 940 JPEGs, the Rebel T7i / 800D can maintain a slightly speedier 6fps burst mode until the card is full (JPEG) or for up to 27 consecutive raw frames. For this to be the case, you need to make sure you’re using a card rated to the UHS-I standard.

11. Dual Pixel AF system

In place of the Hybrid CMOS AF system of its predecessors, the T7i packs in the same Dual Pixel CMOS AF system seen in the EOS 80D, EOS 5D Mark IV and others. This allows for focus tracking and face detection when using live view and shooting videos.

Furthermore, the fact that the Rebel T7i / 800D retains the T6i’s touchscreen means you can simply tap the screen where you want the camera to focus. This partnership has worked very well on other models, and makes focus-pulling during video recoding easy and professional-looking.

12. Full HD recording now at 60p

While the camera doesn't stretch to offering the same 4K video functionality as some of its more advanced siblings, it does up the maximum frame rate in Full HD recording from the T6i’s 30fps to 60fps (59.94fps).

13. Increased battery life

One of the less-exciting – but still significant – changes is an increase in battery life on the EOS Rebel T7i / EOS 800D. Although the new model uses the same LP-E17 battery as the EOS Rebel T6i / EOS 750D, it promises around 600 frames per charge, compared with the 440 frames managed by the T6i.

Both of these figures are quoted for viewfinder use in typical conditions, and are reduced when using Live View, or when working in colder environments.

Canon has also revised the way in which battery life is presented; there are now six levels on display to help you get a better idea of how much juice you’ve got left, and, if that’s not precise enough, you can also have this displayed as a percentage.

14. New connectivity button

The back plate of the EOS Rebel T7i / EOS 800D appears strikingly similar to that of the EOS Rebel T6i / EOS 750D, although one noticeable difference on the new model is the addition of a new connectivity button.

This works with the camera’s built-in Wi-Fi and NFC options, which also featured on the T6i. The EOS Rebel T7i also features Bluetooth like the more senior EOS 77D.

As on the T6i, a small light on one side of the top plate shows connectivity status, although Canon has chosen to restyle and reposition it slightly for the EOS Rebel T7i / EOS 800D.

Verdict

The Rebel T6i / 750D can trace its heritage back to the early days of digital photography and it shows. A very polished and well-thought out camera, the Rebel T6i / 750D is a great introduction to DSLR photography for those looking to make the step up from a compact or smartphone. 

Very comfortable to hold and use, the controls are within easy reach and the touchscreen is very well implemented, allowing you to navigate the menus and make setting selections with you a few taps. It’s also very handy to be able to pinch-zoom into images to check sharpness. 

We particularly liked having a vari-angle screen because it makes it easy to compose images at awkward angles and encourages you to be creative. It’s also helpful to be able to set the AF point and/or trip the shutter with a tap on the screen.

The upgrade to the 24MP sensor is a very welcome improvement over the 18MP chip found in the Rebel T5i / 700D, which combined with excellent phase detection autofocus and metering systems, adds up to a very nice camera.

Competition

Nikon D5600

Perhaps the closest rival to the Rebel T6i / 750D, the D5600 sports a touchscreen vari-angle display and Nikon's SnapBridge connectivity. There isn't much wrong with the D5500's 24.2-megapixel, non-anti-aliased sensor either. It may be pinched from the older D5300, but it still delivers excellent image quality, while the advanced AF system is better than the EOS 750D's.

Canon EOS Rebel T6s / EOS 760D

As we’ve touched upon internally at least, the EOS Rebel T6i / 750D and T6s / 760D are very pretty much identical, but it’s the exterior controls where differences start to appear, notably the addition of a rear thumbwheel and top plate LCD display. Features which only normally appear on Canon’s higher end enthusiast models. For newer users, the T6i is the better bet.
