Pentax K-1 vs K-3 Overview and Optics
The Pentax K-1 outperforms the Pentax K-3 in optics with a score of 85/100 compared to the K-3’s 74/100. Both cameras share some common specifications, such as the CMOS sensor type, Pentax KAF lens mount, and image stabilization. However, the K-1 has distinct advantages that contribute to its higher score.
The K-1 has a 36.4-megapixel sensor, which is significantly higher than the K-3’s 24-megapixel sensor. This difference allows the K-1 to capture more detail and produce higher resolution images. The K-1 also has a full-frame sensor size, which provides better low-light performance and a shallower depth of field than the K-3’s APS-C sensor. Furthermore, the K-1’s Prime IV processor is an upgrade over the K-3’s Prime III processor, offering better image processing capabilities. Lastly, the K-1’s DXOMARK sensor score of 96 is notably higher than the K-3’s score of 80, reflecting the K-1’s superior image quality.
On the other hand, the K-3 does have a faster shooting speed of 8.3 frames per second, compared to the K-1’s 4.4 frames per second. This makes the K-3 better suited for action and sports photography, where capturing fast-moving subjects is crucial.
Taking these factors into account, the Pentax K-1 is the clear winner in terms of optics and image quality. Its higher megapixel count, full-frame sensor, better processor, and higher DXOMARK sensor score all contribute to its superior performance. However, the Pentax K-3 may still be a viable option for those who prioritize fast shooting speeds for action photography.

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. | 204800 | 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. | 33 | 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) |
Pentax K-1 vs K-3 Video Performance
The Pentax K-1 and the Pentax K-3 both have a video score of 70/100, indicating that they have similar video capabilities. They share many common specifications, making them quite comparable in terms of video performance.
Both cameras have a maximum video resolution of Full HD, with dimensions of 1920 x 1080. This ensures that they can produce clear and detailed video content. Additionally, they both have a maximum video frame rate of 60fps, which allows for smooth and fluid motion in captured videos. Time-lapse functionality is also built into both cameras, providing users with the ability to create creative and compelling time-lapse videos.
Since both cameras have the same video score and share many common specifications, it is difficult to determine a clear winner in terms of video capabilities. However, there may be other factors, such as additional features or user preferences, that could influence a buyer’s decision between the two models.
On the other hand, it is also important to consider any areas where one camera may outperform the other. In this case, both cameras share the same video capabilities, so it is unlikely that one camera is significantly better than the other in terms of video performance.
Taking all of these factors into account, it is clear that the Pentax K-1 and the Pentax K-3 are evenly matched in terms of video capabilities. With the same video score and shared specifications, users can expect similar video performance from both models. Ultimately, the choice between the two cameras will likely depend on individual preferences and other factors, such as additional features or price.

Pentax K-1 vs K-3 Storage and Battery
The Pentax K-1 outperforms the Pentax K-3 in storage and battery with a score of 68/100 compared to the K-3’s 63/100. Both cameras share common specifications in this category, including two memory card slots, compatibility with SD/SDHC/SDXC memory cards, the use of D-LI90 battery type, and the absence of USB charging.
The K-1’s superiority in storage and battery is primarily due to its longer battery life of 760 shots, compared to the K-3’s 560 shots. This difference allows photographers to take more images before needing to change or recharge the battery, proving advantageous in various shooting situations.
On the other hand, the K-3 does not have a notable advantage over the K-1 in this category, as both cameras share similar specifications, with the exception of battery life.
Considering the longer battery life of the K-1, it is the clear winner in the storage and battery category. The Pentax K-3, although a solid camera, falls short in comparison to its counterpart, the K-1, when it comes to storage and battery performance.
