The Pentax K-3 outperforms the Nikon D7100 with a score of 69/100 compared to 65/100. Both DSLR cameras were released in 2013, with the Nikon D7100 priced at $1200 and the Pentax K-3 at $1300. They share similar dimensions, with the Nikon measuring 136 x 107 x 76mm and weighing 765g, while the Pentax measures 131 x 100 x 77mm and weighs 800g.
The Pentax K-3’s higher score reflects its superior performance and features. However, the Nikon D7100 has its advantages, such as being slightly lighter and more affordable.
Considering the scores and specifications, the Pentax K-3 is the better choice for those seeking higher performance, while the Nikon D7100 may appeal to those looking for a more budget-friendly option.
The Pentax K-3 outperforms the Nikon D7100 in optics with a score of 74/100, compared to the Nikon’s 67/100. Both cameras share some key specifications, including a CMOS sensor, an APS-C sensor size, and similar megapixel counts (24 for the Pentax K-3 and 24.1 for the Nikon D7100). These similarities ensure that both cameras produce high-quality images.
The Pentax K-3 has a higher shooting speed of 8.3 frames per second, compared to the Nikon D7100’s 6 frames per second. This makes the Pentax K-3 a better choice for capturing fast-moving subjects or shooting in burst mode. Additionally, the Pentax K-3 features image stabilization, which helps to reduce camera shake and improve image sharpness. This feature is absent in the Nikon D7100, making the Pentax K-3 better for handheld shooting.
On the other hand, the Nikon D7100 has a slightly higher DXOMARK sensor score of 83, compared to the Pentax K-3’s 80. This means that the Nikon D7100’s sensor provides slightly better image quality in terms of color depth, dynamic range, and low-light performance. However, the difference in scores is minimal and may not be noticeable in everyday shooting situations.
The choice between these two cameras ultimately depends on individual preferences and shooting needs. The Pentax K-3 offers faster shooting speeds and image stabilization, making it a better option for action photography or handheld shooting. The Nikon D7100 has a marginally better sensor score, which may appeal to those who prioritize image quality above all else.
The Pentax K-3 outperforms the Nikon D7100 in video capabilities, scoring 70/100 compared to the D7100’s 57/100. Both cameras share common video specifications, such as Full HD video resolution, maximum video dimensions of 1920 x 1080, and built-in time-lapse functionality. However, the Pentax K-3 surpasses the Nikon D7100 in certain aspects, making it the superior choice for video recording.
The Pentax K-3 excels with its maximum video frame rate of 60fps, double the D7100’s 30fps. This higher frame rate allows for smoother video playback and provides more options for slow-motion effects in post-production. This significant advantage contributes to the K-3’s higher video score and makes it the preferred option for videographers seeking better performance.
On the other hand, the Nikon D7100 does not offer any specific advantages in video capabilities over the Pentax K-3. Both cameras have the same maximum video resolution and dimensions, and both include time-lapse functionality. The D7100’s lower video score reflects its inferior frame rate and limited video features compared to the K-3.
Considering the video capabilities of both cameras, the Pentax K-3 is the clear winner due to its higher frame rate and overall better performance. While the Nikon D7100 is still capable of producing quality videos, the K-3’s additional features and superior frame rate provide a more versatile and satisfying video recording experience.
The Nikon D7100 and Pentax K-3 both have a feature score of 59 out of 100. Despite having the same score, there are differences in their features, making one camera better for certain users.
Both cameras share a 3.2-inch screen size and lack touchscreens, flip screens, and GPS. However, the Nikon D7100 has a higher screen resolution at 1,228,800 dots, compared to the Pentax K-3’s 1,037,000 dots. This means the D7100 provides a clearer and more detailed display for image preview and menu navigation.
The Nikon D7100 also has built-in WIFI, allowing users to transfer images wirelessly and control the camera remotely using a smartphone. This feature is absent in the Pentax K-3, which may be a drawback for users who value wireless connectivity.
On the other hand, the Pentax K-3 has no significant advantages over the Nikon D7100 in terms of features. Both cameras excel in their respective areas, but the D7100 has a slight edge with its higher screen resolution and WIFI capability.
Considering these points, the Nikon D7100 is better suited for users who prioritize image preview quality and wireless connectivity. The Pentax K-3, while not having any notable advantages, remains a solid option for those who do not require the additional features found in the D7100. Despite their equal feature scores, the D7100’s enhancements make it the more appealing choice for certain photographers.
The Nikon D7100 emerges as the winner in the storage and battery category with a score of 76/100, while the Pentax K-3 scores 63/100. Both cameras have two memory card slots and accept SD, SDHC, and SDXC cards. Neither camera offers USB charging.
The Nikon D7100 outshines the Pentax K-3 with its longer battery life, providing 950 shots per charge compared to the K-3’s 560 shots. The D7100 uses the EN-EL15 battery, which contributes to its superior performance in this aspect.
On the other hand, the Pentax K-3 does not have any clear advantages in the storage and battery category. Both cameras share similar storage capabilities, and its battery life falls short compared to the D7100.
