Nikon D810 vs Sony a7S Overview and Optics

The Nikon D810 outperforms the Sony a7S in optics with a score of 76/100, while the Sony a7S scores 60/100. Both cameras have similar specifications, such as a shooting speed of 5 frames per second, CMOS sensor type, full-frame sensor size, and no image stabilization. They also have different lens mounts, with the Nikon D810 using the Nikon F FX mount and the Sony a7S using the Sony FE mount.

The Nikon D810 is better in terms of optics due to its higher megapixel count of 36.3, which enables it to capture more detailed images compared to the Sony a7S with 12.2 megapixels. Additionally, the D810’s Expeed 4 processor and a DXOMARK score of 97 for its sensor contribute to its superior performance in capturing high-quality images.

On the other hand, the Sony a7S has its advantages. Its Bionz X processor allows for faster image processing and better low-light performance. The lower megapixel count also results in larger individual pixels on the sensor, which can be beneficial for low-light photography. However, the a7S’s DXOMARK score of 87 for its sensor is lower than the D810’s, indicating that the overall image quality may not be as impressive.

Considering the specifications and scores, the Nikon D810 stands out as the better option for photographers who prioritize high-quality images and detail. The Sony a7S, while not as strong in optics, may still be suitable for those who require better low-light performance and faster image processing.

Nikon D810 vs Sony a7S Video Performance

The Nikon D810 outperforms the Sony a7S in video capabilities, earning a score of 70 out of 100 compared to the Sony a7S’s 56. Both cameras share several common specifications, including Full HD video resolution with maximum dimensions of 1920 x 1080 pixels and a maximum video frame rate of 60fps.

The Nikon D810 has an advantage over the Sony a7S with its built-in time-lapse functionality, which allows users to create stunning time-lapse videos without requiring additional equipment or software. This feature is particularly useful for capturing scenes with gradual changes, such as sunsets or the movement of stars in the night sky. The Sony a7S lacks this built-in feature, making it less versatile for time-lapse videography.

While the Sony a7S does not excel in any specific video aspect compared to the Nikon D810, it still provides good video quality with identical resolution, dimensions, and frame rate. However, the lower score indicates that the overall video performance may not be as strong as the Nikon D810.

Taking into account the video specifications and scores, the Nikon D810 is the superior choice for videographers. Its built-in time-lapse functionality sets it apart from the Sony a7S, providing an additional creative tool for users. Although the Sony a7S offers similar video quality in terms of resolution and frame rate, its lack of time-lapse functionality and lower overall score make it a less competitive option for video enthusiasts.

Nikon D810 vs Sony a7S Features and Benefits

The Nikon D810 emerges as the winner in the features comparison with a score of 59/100, while the Sony a7S trails behind with a score of 54/100. Both cameras share some common specifications, such as the lack of a touchscreen and GPS, as well as the inclusion of WiFi connectivity. However, the differences in their features contribute to the disparity in scores.

The Nikon D810 surpasses the Sony a7S in terms of screen size and resolution. Its 3.2-inch screen is larger than the 3-inch screen found on the Sony a7S. Additionally, the Nikon D810 boasts a higher screen resolution of 1,229,000 dots compared to the Sony a7S’s 921,000 dots. This results in a crisper and more detailed display on the Nikon D810, making it more enjoyable to use for image review and menu navigation.

On the other hand, the Sony a7S does have one advantage over the Nikon D810: it features a flip screen. This allows for greater flexibility in composing shots from various angles, particularly when shooting from low or high perspectives. The Nikon D810 lacks this useful feature.

Considering the features of both cameras, the Nikon D810 stands out as the better choice due to its larger, higher-resolution screen. While the Sony a7S does offer the advantage of a flip screen, this single feature may not be enough to compensate for the overall lower feature score. Ultimately, the Nikon D810’s superior features make it a more versatile and user-friendly camera compared to the Sony a7S.

Nikon D810 vs Sony a7S Storage and Battery

The Nikon D810 outperforms the Sony a7S in storage and battery, scoring 79/100 compared to the Sony’s 21/100. Both cameras accept SD/SDHC/SDXC memory cards and lack USB charging. However, the D810 has two memory card slots and also supports Compact Flash and UDMA cards, while the a7S only has one slot and supports Memory Stick Duo/Pro Duo/Pro-HG Duo cards.

The D810’s battery life is significantly longer at 1200 shots, using an EN-EL15 battery, compared to the a7S’s 380 shots with its NP-FW50 battery. This difference in battery life gives the D810 a clear advantage for extended shooting sessions.

Although the Sony a7S has a lower score in storage and battery, it does not necessarily mean it is an inferior camera. The a7S may excel in other aspects, such as video performance or low-light capabilities. However, when considering storage and battery alone, the Nikon D810 stands out as the superior choice.
