Canon EOS Rebel T7i / 800D vs EOS Rebel T8i / 850D Overview and Optics
The Canon EOS Rebel T7i / 800D outperforms the Canon EOS Rebel T8i / 850D in optics, scoring 64/100 compared to the T8i’s 57/100. Both cameras share common specifications, including 24 megapixels, CMOS sensor type, APS-C sensor size, Canon EF/EF-S lens mount, and lack of image stabilization. However, the T7i has a better DXOMARK sensor score of 79, while the T8i scores 58.
The T7i’s higher DXOMARK sensor score indicates superior image quality, largely due to its Digic 7 processor. This processor contributes to better low-light performance, color depth, and dynamic range. Thus, the T7i provides more accurate and detailed images in various lighting conditions.
On the other hand, the T8i has a faster shooting speed (7.5 fps) compared to the T7i (6 fps), thanks to its Digic 8 processor. This advantage allows the T8i to capture fast-moving subjects with greater ease. Nonetheless, this improvement in shooting speed is not enough to compensate for the lower image quality provided by the T8i’s sensor.
In terms of optics, the Canon EOS Rebel T7i / 800D is the superior camera due to its higher DXOMARK sensor score and better overall image quality. However, the Canon EOS Rebel T8i / 850D offers a faster shooting speed, which may appeal to users who prioritize capturing fast action. Ultimately, photographers must weigh their specific needs and preferences to determine which camera best suits their requirements.

Megapixels The higher the number of megapixels, the more detail the cameras sensor can capture. | 24 MP | 24 MP | |
|---|---|---|---|
Image Resolution Image resolution is measured in pixels and megapixels, width by height. The higher the number, the higher its resolution. | 6000 x 4000 px | 6000 x 4000 px | |
Sensor Type The camera sensor captures light and records the image. Sensors vary in physical size, the number of pixels, and quality. | CMOS | CMOS | |
Sensor Size The sensor size contributes to the overall quality as well as the dynamic and tonal range a camera can capture. As a rule of thumb, the more surface there is to read the light, the more information it will capture. | 14.9 x 22.3 mm | 14.9 x 22.3 mm | |
Sensor Format Refers to the most commonly used sensor sizes. |  APS-C | APS-C | |
Frame Rate The number of sequential frames per second the camera can write to the memory card when shooting in burst or continuous mode. | 6 fps | 7.5 fps | |
Lens Mount The lens mount will tell you what type of lens range you can fit onto the camera body. Often the same camera company will have different lens ranges for different cameras. | Canon EF/EF-S | Canon EF/EF-S | |
Image Processor The image processor in the camera converts the information collected on the sensor for digital storage on the memory card. | Digic 7 | Digic 8 | |
Aspect Ratio The aspect ratio refers to the proportional difference between width and height. The most popular aspect ratios are 3:2 and 4:3. |  3:2 | 3:2 | |
Minimum ISO (Native) Refers to the lowest native (or 'base') ISO setting. Lower ISO are less sensitive to light but make a cleaner image. | 100 | 100 | |
Maximum ISO (Native) Refers to the highest native (or 'base') ISO setting. Higher ISO is necessary for low-light situations or night photography, but higher ISOs often introduce grain or noise. | 25,600 | 25,600 | |
Minimum ISO (Expanded) Expanded (or extended) ISO is a digitally enhanced feature available on some cameras. It allows you to push beyond the native ISO range if necessary. | 100 | 100 | |
Maximum ISO (Expanded) Expanded (or extended) ISO is a digitally enhanced feature available on some cameras. It allows you to push beyond the native ISO range if necessary. | 51200 | 51200 | |
Minimum Shutter Speed The minimum shutter speed will tell you the longest exposure your camera can take without using an external accessory. | 30 s | 30 s | |
Maximum Shutter Speed The maximum shutter speed tells you the length inside 1 second the camera will capture. These can sometimes be extended with accessories such as extra external batteries. | 1/ 4000 s | 1/ 4000 s | |
Autofocus Points Autofocus points show where the camera is focusing graphically as squares or brackets in Live View or on an electronic viewfinder. These points are also used for light meter readings. | 45 | 45 | |
In-body Stabilization In-body Stabilization means the camera has a certain technology embedded that counteracts camera shake. |   | | |
Viewfinder Type The viewfinder type is either electronic or optical. Electronic viewfinders will have a small screen in the viewfinder. Optical viewfinders will use prisms and mirrors to look through the lens. | Optical (pentamirror) | Optical (pentamirror) |
Canon EOS Rebel T7i / 800D vs EOS Rebel T8i / 850D Video Performance
The Canon EOS Rebel T8i / 850D outperforms the Canon EOS Rebel T7i / 800D in video capabilities, with a video score of 83/100 compared to the T7i’s 70/100. Both cameras share some common specifications, such as a maximum video frame rate of 60fps and built-in time-lapse functionality. However, the T8i has distinct advantages that contribute to its higher score, while the T7i has limited benefits in this category.
The T8i’s primary advantage is its 4K video resolution, which offers a significant improvement over the T7i’s Full HD resolution. With the T8i’s maximum video dimensions of 3840 x 2160, users can capture much more detailed and high-quality footage compared to the T7i’s 1920 x 1080 dimensions. This difference in resolution is a key factor in the T8i’s higher video score.
In contrast, the T7i struggles to compete with the T8i in video capabilities. While both cameras have a maximum video frame rate of 60fps, the T7i’s lower video resolution limits its overall performance. There are no specific areas where the T7i surpasses the T8i in terms of video capabilities.
Considering these factors, the Canon EOS Rebel T8i / 850D is the superior choice for video performance due to its 4K resolution and higher video score. The Canon EOS Rebel T7i / 800D falls short in comparison and does not offer any unique advantages in this category.
