Read my guide for Canon cameras here. DxOMark tested the Canon EOS Rebel T6i and T6s DSLRs and found their sensor score practically identical. Below is an excerpt of their findings :
Rebel T6i (EOS-750D) 'As an entry-level model the Canon EOS 750D (T6i) makes some compromises in layout and controls — for example, there’s no top plate LCD as found on the EOS 760D(T6s), but sensor performance is on par with the camera maker’s mid- and high-end models, the EOS 70D and the recently-introduced EOS 7D Mk II. While it’s true that the Canon sensors are behind the very best APS-C models in terms of low ISO performance (particularly noticeable when comparing dynamic range), the company is making some noteworthy advances.'
Rebel T6s (EOS-760D) 'While it’s not our place to discuss why Canon should choose to introduce two models that vary mostly by their controls (although the 760D’s tracking AF capability in live view is likely a worthwhile feature), the sensor performance for the EOS 760D is intriguing. Canon has made significant advances over the previous generation sensor, particularly with regard to low ISO noise levels and improved dynamic range. While sensor performance is still behind the very best APS-C models, Canon appears to be taking up the challenge set by Sony, and while it’s still got some way to go, that has to be good news for the consumer.'

There may be an issue with some sensors in the new Canon Rebel T6i and T6s cameras. LensRental.com discovered a 'bad' batch with dot marks on the sensor. Imaging Resource has done some tests to measure the image quality from the 'affected' Rebel T6s and Rebel T6i cameras. A brief follow-up from LensRentals.com states that Canon is taking the issue very seriously and we should hear some kind of an official statement from Canon soon.
As far as image quality issues with affected units, Imaging Resource had this to say :
"The good news is that (a) the actual impact on photos is pretty small, and even then is limited to shots captured with very small apertures; and (b) it’s quite easy to tell whether any given camera has flecks or not. I’d personally be comfortable buying either of these models myself, and either exchanging it with the retailer if it proved to have flecks, or waiting for what I expect will be an eventual repair program from Canon to deal with the issue. (Note that we have absolutely no direct information from Canon on this; this is just personal opinion at this point.)"
Below is the article on the subject from LensRental.com :
"Every once in a while we notice something, because of the large quantities of cameras and lenses we buy, that we think people should be aware of. This particular issue won't affect our renters; we've sent the affected cameras back. It may not affect very many people at all, since this is from a relatively small sample size. But I still think it worth mentioning. The bottom line is that 4 of the Canon T6s and 2 of the T6i cameras we received had to be sent back because of a defect in the sensor stack (the layers of filter glass over the sensor). This is out about 10 copies of each; the others were absolutely perfect. But when the techs couldn't clean the 'dust' off, they alerted us. Closer examination with a 10X microscope show the spots are inside, within the stack and under the top layer of glass. I would assume it's a defect in the adhesives used to put the layers of glass together, but I don't know for certain. One person has suggested there may have been dust on the glass when the adhesive was applied, which seems logical, but again, I have no real knowledge of how it happens. The affected cameras all looked exactly the same, so I won't bore you with more images. It's quite easy to see, even without a sensor loupe, so don't make yourself crazy trying to find it on your camera; if it's there, you'll notice it. Actually it's easier to see without a sensor loupe. Angled light seems to show it up very clearly, lights shining directly down on the sensor not quite as much. The other cameras had no signs of this at all, so it was either a 'yes' or 'no' situation. We didn't see any cameras with just a few dots. We took a number of images to see how much they would show up on an actual photograph. In wider aperture shots, as you'd expect, they don't show up at all. At about f/11 to f/16, taking pictures of sky, clouds, or a well-lit white wall, they do become apparent, but they aren't as bad as I would have expected. They're also have a very different appearance than dust on the sensor does. These have have a ringed, or target appearance rather than the dark blob that sensor dust has. Below is a 100% crop from the corner of the camera with the sensor pictured above. Remember, this is an f/16 image of a clear sky. In a regular photograph at wider apertures I doubt you'd notice it. All of the cameras we received had early SNs, and there is not going to be a direct serial number correlation with the problem. For example, we had 7 cameras in the SN 0220310007X range. Cameras with the last digit of 2 and 4 were affected, but 3 and 6 were not. That's not surprising, really, since sensors would be manufactured somewhere else and then placed into the camera during assembly. I've talked to people at Canon about this issue and they are aggressively looking into it. It will take some time for them to figure out what the issue is, where it occurred, and what cameras might be affected. They're actively looking into the situation. They are NOT telling me, as some manufacturers do, that there is no problem. My guess, and it's just a guess, is that a bad batch of sensors were made, quality control missed this, and they got put into cameras. How big is a batch? I have no clue. Maybe it's just a few hundred and we happened to get a lot (all of the cameras we've received have been pretty close in serial number). Maybe it's thousands. Time will tell and I'm comfortable the problem is being addressed. Oh, and for those of you who want to bash Canon Quality Control over this, well it's appropriate, I won't stand in your way. But I can't because when I looked at these cameras myself the first time, I missed two of the ones with bad sensors. Like I mentioned earlier, direct light through a sensor loupe didn't reveal it nearly as well as an angled spot light did. (Now you know how we figured that out.) It's possible the inspection of the sensors after assembly is done using a direct light, or some other automated equipment that isn't capable of seeing this. So I'm not throwing any stones out of my glass house. And having dealt with many manufacturers concerning many issues over the years, I'm just pleased that this issue is being taken seriously and investigated immediately. That's not always the case. In the meantime, check your new T6 when you get it, return it if you need to."
MELVILLE, N.Y., February 5, 2015 – Canon U.S.A., Inc., a leader in digital imaging solutions, today announced the addition of two new DSLR cameras to its popular EOS Rebel lineup: the EOS Rebel T6s Digital SLR camera, and the EOS Rebel T6i Digital SLR camera. Featuring a newly developed 24.2 megapixel Canon CMOS imaging sensor, both cameras deliver the highest resolution available amongst EOS models with an APS-C format sensor. Additionally, the cameras feature built-in Wi-Fi® and NFC™ capabilities – a first for the Canon EOS Rebel system – making snapping and sharing high-quality, treasured images seamless.
“The Canon EOS Rebel series is one of the most popular lines of DSLR cameras on the market, and we are proud to continue to innovate and upgrade this line with features such as wireless connectivity and improved image capture capabilities,” said Yuichi Ishizuka, president and COO, Canon U.S.A., Inc. “As the popularity of this line grows with consumers, we’re excited to launch the EOS Rebel T6s as our new flagship camera in the Rebel line, as well as have another budget-conscious offering in the line with the Rebel T6i.”
With multiple features most commonly found in advanced amateur cameras, the EOS Rebel T6s is designed for photography enthusiasts, or those who are already experienced with entry-level cameras who want to take high-quality photos and videos, and look for more advanced features and functions. For more casual photography needs, or for users looking to purchase their first DSLR camera, the EOS Rebel T6i camera prioritizes affordability, without sacrificing basic SLR performance attributes like quick shutter response, and compatibility with Canon’s impressive line of interchangeable lenses and accessories.
Outstanding Image Capture Features The new EOS Rebel cameras have an extensive ISO range of 100-12800 (expandable to 25600) to accommodate shooting situations ranging from bright sunny days at the beach to dimly lit indoor dance recitals. The high-performance DIGIC 6 image processor helps provide outstanding image quality and speed, so pictures are clear and sharp.
Building on the image capture functionality of their predecessors, the EOS Rebel T6s and EOS Rebel T6i cameras feature Canon’s new Hybrid CMOS AF III image sensor-embedded autofocus system, which allows for high levels of speed and accuracy when capturing Full HD video or high-resolution photos in Live View. This is particularly useful when capturing children playing sports, or animals in the wild, when it’s imperative to get the shot at the exact moment action is happening. Helping photographers capture those special moments, the cameras have high-speed continuous shooting up to five frames-per-second (fps). For photographers who prefer to compose their images through a viewfinder, the new EOS Rebel T6s and EOS Rebel T6i cameras have a 19-point all cross-type AF system that allows for superb autofocus, as well as focus area selection modes.
Brand-new to the EOS Rebel line, the cameras feature built-in wireless capabilities, which allow users to wirelessly transfer images and videos with ease to compatible smartphones and tablets through Canon’s newly updated and free Camera Connect app.2 Images and videos can also be shared wirelessly to a wide range of popular social networking sites through Canon iMAGE GATEWAY. 3 The camera’s built-in NFC (Near Field Communication)4 allows quick and simple pairing to a compatible Android device, or devices that support NFC like the new Canon Connect Station CS100 photo and video storage and sharing device. The built-in Wi-Fi functionality also allows users to wirelessly print their images to any compatible printer, like the PIXMA MG7520 or PIXMA iP8720.
With an intuitive design that allows for an optimal photographic experience, the new EOS Rebel cameras have a three-inch Vari-Angle Touch Screen Clear View LCD monitor with approximately 1,040,000 dots. This design enables flexible positioning for high or low framed shots, as well as clear viewing even when outdoors in the sunlight. Additionally, the cameras feature the latest version of Canon’s EOS scene analysis system, which helps photographers capture beautiful images in a wider range of situations by detecting near-infrared light and flickering light sources. Also new to the entire EOS system, both models feature color tone detection, which helps ensure individuals in photographs are properly focused and/or exposed by adjusting both autofocus and exposure metering.
Full HD Video Capture The EOS Rebel T6s and EOS Rebel T6i cameras feature EOS Movie mode which captures Full HD 1080p resolution video up to 30 fps in MP4 format for high quality shooting and easy movie sharing on select social networking sites. Manual exposure control, digital zoom and an external stereo microphone jack are provided for advanced users using the EOS Rebel T6s.
Expanded Creative Functionality Allowing for full creative control, the new EOS Rebel cameras offer creative filters available as presets for photos and movies. These filters can be displayed in real time during Live View shooting, providing an easy way for users to enhance their creative work. Users can further expand their artistic abilities right from the camera with Creative Filters such as Fisheye Effect, Toy Camera Effect and Monochrome mode. Fisheye Effect gives images a panoramic look and feel, Toy Camera Effect adds a grainy look to soften photos, illustrating a vintage appearance and with Monochrome mode, photos can either have black-and-white, blue or sepia tones, to display a more classic appearance.
Advanced Features & Capabilities For photographers who desire more advanced features, the EOS Rebel T6s is the first EOS Rebel class DSLR camera to feature a top LCD panel, Quick Control Dial, Horizontal Level and built-in HDR movie capabilities. The new camera is also the first model in the EOS Rebel series to feature Servo AF in Live View, allowing continuous tracking of moving subjects during burst mode shooting sequences.
Availability The EOS Rebel T6s Digital SLR camera and EOS Rebel T6i Digital SLR camera are scheduled to be available at the end of April 2015. The estimated retail price of the EOS Rebel T6s is $849.99 for the body only, and $1,199.00 bundled with an EF-S 18-135 STM lens. The EOS Rebel T6i has an estimated retail price of $749.99 for the body only, $899.99 bundled with an EF-S 18-55 STM lens, and $1,099.00 bundled with an EF-S 18-135 STM lens.
