Canon EOS 7D vs Pentax K-3 Overview and Optics
The Pentax K-3 outperforms the Canon EOS 7D in terms of optics, with a score of 74/100 as opposed to the Canon’s 43/100. Both cameras share common specifications such as an APS-C sensor size, CMOS sensor type, and a similar shooting speed (8.3 fps for Pentax K-3 and 8 fps for Canon EOS 7D). However, the Pentax K-3 has certain advantages that contribute to its superior score.
The Pentax K-3 has a higher megapixel count at 24 compared to the Canon EOS 7D’s 18 megapixels. This means that the Pentax K-3 can capture more detailed images. Additionally, the Pentax K-3 has a higher DXOMARK score for its sensor, standing at 80 compared to the Canon EOS 7D’s 66. This signifies better image quality and low-light performance. Moreover, the Pentax K-3 has image stabilization, which the Canon EOS 7D lacks. This feature helps in reducing camera shake and results in sharper images.
On the other hand, the Canon EOS 7D has a dual Digic 4 processor, while the Pentax K-3 has a single Prime III processor. However, this difference does not seem to give the Canon EOS 7D a significant advantage in terms of image processing.
In terms of optics, the Pentax K-3 is the clear winner due to its higher megapixel count, better sensor performance, and image stabilization feature. The Canon EOS 7D falls short in these aspects, making it a less favorable option for those prioritizing image quality and stability.

Megapixels The higher the number of megapixels, the more detail the cameras sensor can capture. | 18 MP | 24 MP | |
|---|---|---|---|
Image Resolution Image resolution is measured in pixels and megapixels, width by height. The higher the number, the higher its resolution. | 5184 x 3456 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. | 14.9 x 22.3 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. | 8 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. | Dual Digic 4 | 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. | 6,400 | 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. | 12800 | 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. | 0 | 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 7D vs Pentax K-3 Video Performance
The Pentax K-3 outperforms the Canon EOS 7D in video capabilities, scoring 70 out of 100 points, while the Canon EOS 7D scores 43 points. Both cameras share some common specifications, such as Full HD video resolution and maximum video dimensions of 1920 x 1080. However, there are notable differences that make the Pentax K-3 a superior choice in terms of video performance.
The Pentax K-3 has a higher maximum video frame rate of 60fps, compared to the Canon EOS 7D’s 30fps. This allows for smoother video playback and is particularly beneficial for recording fast-paced scenes or capturing slow-motion footage. Additionally, the Pentax K-3 features built-in time-lapse functionality, enabling users to create stunning time-lapse videos without the need for additional equipment or software.
While the Canon EOS 7D falls short in comparison to the Pentax K-3, it still offers decent video performance for casual users. Its Full HD video resolution and 1920 x 1080 video dimensions ensure that users can capture high-quality footage, albeit at a lower frame rate than the Pentax K-3.
