Canon EOS 70D vs Pentax K-3 Overview and Optics
The Pentax K-3 emerges as the winner in the optics comparison, with a score of 74/100, while the Canon EOS 70D scores 58/100. Both cameras share common specifications, such as the CMOS sensor type, APS-C sensor size, and similar processors – Digic 5+ for the Canon EOS 70D and Prime III for the Pentax K-3.
The Pentax K-3 surpasses the Canon EOS 70D with its higher megapixel count of 24, compared to the Canon’s 20.2. This difference allows the K-3 to capture more detailed images. Additionally, the K-3 has a faster shooting speed of 8.3 frames per second, providing an advantage in capturing fast-moving subjects. The K-3 also has a superior DXOMARK sensor score of 80, compared to the 70D’s score of 68, indicating better overall image quality. Furthermore, the K-3 features image stabilization, which the 70D lacks, ensuring sharper images in challenging shooting conditions.
On the other hand, the Canon EOS 70D has the advantage of a more extensive lens selection due to its Canon EF-S lens mount. This feature provides users with a broader range of lenses to choose from, catering to various photography needs and preferences.
Taking these factors into account, the Pentax K-3 stands out as the better camera in terms of optics, with superior image quality, faster shooting speed, and image stabilization. However, the Canon EOS 70D still holds its ground with a wider lens selection, which may appeal to photographers seeking versatility. Ultimately, potential buyers should weigh these considerations based on their specific photography requirements and preferences.

Megapixels The higher the number of megapixels, the more detail the cameras sensor can capture. | 20.2 MP | 24 MP | |
|---|---|---|---|
Image Resolution Image resolution is measured in pixels and megapixels, width by height. The higher the number, the higher its resolution. | 5472 x 3648 px | 6016 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. | 15 x 22.5 mm | 15.6 x 23.5 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. | 7 fps | 8.3 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-S | Pentax KAF | |
Image Processor The image processor in the camera converts the information collected on the sensor for digital storage on the memory card. | Digic 5+ | Prime III | |
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. | 12,800 | 51,200 | |
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. | 25600 | 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/ 8000 s | 1/ 8000 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. | 19 | 27 | |
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 (pentaprism) | Optical (pentaprism) |
Canon EOS 70D vs Pentax K-3 Video Performance
The Pentax K-3 outperforms the Canon EOS 70D in video capabilities, with a video score of 70/100 compared to the 70D’s 43/100. Both cameras share some common specifications, such as Full HD video resolution and maximum video dimensions of 1920 x 1080. However, the K-3 surpasses the 70D in other aspects, contributing to its higher score.
The Pentax K-3 offers a higher maximum video frame rate of 60fps, which is double the 30fps offered by the Canon EOS 70D. This higher frame rate allows for smoother video playback and better slow-motion effects in post-production. Additionally, the K-3 has built-in time-lapse functionality, which the 70D lacks. Time-lapse is a popular feature for capturing dynamic scenes, such as sunsets or cityscapes, over an extended period.
Despite its lower video score, the Canon EOS 70D does have some advantages over the Pentax K-3, although they may not be as significant for videographers. For instance, the 70D is known for its excellent autofocus system, which can be beneficial for video shooting. However, this advantage may not be enough to make up for the superior video capabilities of the K-3.
Taking all factors into consideration, the Pentax K-3 is the clear winner in terms of video capabilities. With its higher video frame rate and built-in time-lapse functionality, the K-3 offers more versatility and potential for creative expression in video production. While the Canon EOS 70D may have some advantages in other areas, it falls short in comparison to the K-3’s superior video performance.

Canon EOS 70D vs Pentax K-3 Features and Benefits
The Canon EOS 70D emerges as the winner with a feature score of 70/100, while the Pentax K-3 trails behind with 59/100. Both cameras have a few specifications in common, such as a screen size of approximately 3 inches and a similar screen resolution (1,040,000 dots for the EOS 70D and 1,037,000 dots for the K-3). Additionally, neither camera has GPS or Bluetooth capabilities.
The Canon EOS 70D outshines the Pentax K-3 in several ways. One key advantage is its touchscreen feature, which the K-3 lacks. This allows for easier navigation and control of the camera’s settings. Furthermore, the EOS 70D has a flip screen, enabling users to shoot from various angles and positions comfortably. Lastly, the EOS 70D comes with Wi-Fi, making it convenient for users to transfer files and control the camera remotely.
On the other hand, the Pentax K-3 has a slightly larger screen size at 3.2 inches compared to the EOS 70D’s 3-inch screen. However, this minor advantage does not outweigh the additional features offered by the Canon EOS 70D.
Taking all these points into consideration, the Canon EOS 70D proves to be a better camera due to its enhanced features such as the touchscreen, flip screen, and Wi-Fi capabilities. These additional features provide users with a more versatile and user-friendly experience compared to the Pentax K-3. Although the K-3 has a marginally larger screen, it falls short in offering the same level of convenience and functionality as the EOS 70D.
