Canon 760D (T6i) CMOS sensor review

Canon 760D T6i

Powerful Canon 760D with a high quality sensor

Canon EOS Rebel T6i (EOS 760D) camera has new improved 24.2 MP APS-C CMOS Sensor (22.3mm x 14.9mm, crop factor 1.6x) with on-sensor phase detection pixels and a low-pass filter that blocks high spatial frequencies to reduce the moiré and false-color effects, 3.7µm photodiodes, color-sensitive meter sensor for improved accuracy. IR-absorbing/UV-blocking glass filter: Blocks light outside the visible spectrum, to improve color fidelity and image quality, Primary color filter: separates the light into primary (RGB), Imaging element: Receives the light and turns it into a digital signal.

DIGIC 6 image processor with 14-bit processing and 24.2 MP image sensor enable wide dynamic range, high range ISO performance for its class: native: 100 to 12,800, expandable to 25600; AutoISO up to 6400, video recording mode: 12800, low noise on high ISO and fast autofocus in Live-view mode.

Canon 760D (T6i) includes new 19 points Hybrid CMOS AF III uses sensor-based phase detection points for increased focus speed and accuracy in live view.

Canon USA confirmed that some T6i cameras affected by the speckled sensor, which resulted in the appearance of dark circular patterns.

Best Camera Image Sensor Manufacturers 2016: Where they are now

Image sensor vendors

image-sensor-vendors
As far as camera sensors go and CMOS Image Sensor technology, while Sony, Omnivision, Samsung, and Canon have led the way in the past, consumers today have evolved and technology isn’t the only key determining factor now in demand. Customers demand, and have received over the years great quality products and reliable cameras and CMOS image sensors from other companies such as Toshiba, and of course the more well-known Nikon, and, most recently Sony, Canon, and Lumix also appear to be leading the way.

Manufacturers like Canon over the years have claimed to the public that they produce each of their EOS sensors in-house, but given demand they appear to have given way to the consideration of outsourcing of the past 2 years or so.

Fuji, another relatively well known and highly respectable camera and camera sensor manufacturer have actually evolved to relying on Toshiba and Sony for their chip technology, but separate themselves from the ‘outsourcing cliche’ by standing behind their own in-house branded sensors like the EXR of the CFA.

Then you take a company like Nikon, who shares and often relies on sensor technology from partner company Sony, but Sony appears to have overall dominated Nikon’s camera sensor chip development, as they rely on Renesas or TSMS to produce the customized or special request Nikon designed chips as needed. And although they’ve been known to also call on trusted manufacturers like Toshiba (such as for their D5200 camera last year, consumers don’t appear to look on this unkindly as their both quite long-term, trusted brands.

In consideration of other big name brands for cameras and camera sensors, a company like Samsung (who’s also partnered with manufacturer Pentax), are now using each other’s technologies in some cases to design sensors, while Samsung appears to be the dominant party in these transactions. It’s also worth mentioning on a side note that those relations and technology sharing or ordering between Samsung and Pentax has since expired or at least is no longer conducted on the scale it was back in 2015.

While other major manufacturers like Sigma has begun outsourcing from their originally in-house camera sensors to other substantially large manufacturers like Fujitsu, a fairly known and trusted technology equipment and service provider, ran out of the Philippines but hosted and controlled by its headquarters in Tokyo, Japan.

Relatively known and fairly trusted other manufacturers like Pentax rely on Samsung, and often the retro but nonetheless trusted and reputable Kodak brand and major manufacturer of original, camera technology. Last year both Canon and Sony demonstrated their commitments as major manufacturers of cameras and camera sensor technologies to really step up their game and set the bar high. You can see that in the ESO camera sensor technology, such as Canon’s 5DS and 5DSR 35mm full frames from last year.


Sony, on the other hand, has made tremendous technological advancements with both it’s CMOS sensor for mobile devices and digital cameras – including the releases of the DSC-RX100 IV and the DSC-RX10 II last year. This added back-illuminated advancement of technology has provided solutions to the circuitry involved with limiting light gathering abilities within its photodiodes as seen with its technology and cameras in the past, really setting the stage for its digital cameras this year.

Best camera air blower for lens/sensor cleaning 2016-2017

Top 5 camera sensor air blowers (sensor/lens cleaning kits) 2015-2016

improved-zeeion-blower-camer-sensor-blower

Improved Zeeion® Blower

The Improved Zeeion Blower was our #1 choice for cleaning your camera lens and sensor because it has been made with the most precision-based materials to be most effective at not only cleaning, but also preventing damage to your valuable camera parts.

The Zeeion Blower uses reverse static electricity, therefore keeping unwanted currents and attraction of dust and particles from remaining both inside your lens, as well as on your camera sensor. On top of all these great features, it also has a dust-free ejection method which means it filters both what it expels, as well as consumes through a buffering process. Consumers want a lens and sensor cleaner that will prevent any harmful chemicals from getting inside of the device which in turn could damage your camera sensor or lens.

Giottos-Rocket-Air-Blaster-Air-Blower

Giottos Rocket Air Blaster Air Blower, Large

The Giotto’s Rocket Air Blaster is our second top choice for camera lens cleaning and sensor maintenance. This product has very positive reviews for being effective at adequately cleaning the camera lens to rid it of unwanted particles or dust.

In regards to cleaning a camera sensor, this specific duster recommends a ‘wet’ method which many consumers are hesitant to apply. Also, given the pointy and potentially abrasive material and shape of the plastic tip, it’s possible that such usage could damage a sensor so it may be best to only use this one for lens cleaning, and use a separate product for your camera sensor.

Camera-sensor-lens-FireFly-Air-Blower

FireFly Air Blower

This is a very sophisticated device that blows ionized air against your camera sensor, removing static charge, and in turn removing unwanted particles, dust, or dirt from your camera sensor.

Likewise, the same tool and methods then could be used for cleaning your camera lens as well. This looks like a nice sophisticated little device, but does not hav a lot of feedback or reviews, Given it’s very cheap price, a lot of premium-camera owners might be hesitant to try out or count on an air-blower such as this—especially since it involves chemically scientific interactions with their sometimes thousands of dollar cameras, lens, or sensor device.

Samsung-TL205-Digital-Camer

Samsung TL205 Digital Camera Cleaning Kit

While there’s not a lot of feedback or reviews for this product, Samsung does has a strong, consistently reliable reputation.

The kit seems pretty basic, and considering all of its (considerably large) physical components, it seems this kit is most focused on cleaning your lens with adequate tools and wipes, etc. There doesn’t seem to be much, if any, of a focus on safely cleaning your camera sensor with this kit, so that’s definitely a downfall—but sometimes, the best products are separate, not combined. One hand doesn’t always necessarily wash the other, so it’s important to use your discretion when purchasing kits like this that seem to use archaic-like methods or tools—i.e. Q-Tips.

hahnel-4-in-1-camera-lens-cleaning-kit

Hahnel 4-in-1 Camera Cleaning Kit

Last but not least, the Hahnel 4-in-1 Camera Cleaning Kit is by no means a poor choice for cleaning and maintaining your high performance camera lens. Safe liquids, a cloth, an air blower, and even a lens pen is provided with this cleaning kit, making it most practical for cleaning your camera lens.


Unfortunately, outside of the practical usage of compressed air against dirt within your sensor, as ineffective as it might be, this may not be the most ideal or safest product to use for cleaning it.

It’s likely that through the static electricity generated by using this blower to clean a sensor that you could actually damage it, or just simply not remove the particles and unwanted dirt at all.
