Appearance Design
Nikon Z8: The body weighs approximately 810g, much lighter than the Nikon Z9, and its size is closer to that of the Nikon D850, but even smaller and lighter. The design of its pentaprism housing is exactly the same as that of the Nikon Z9, with obvious recognition. The overall button layout is closer to the design of the Nikon Z9. However, there is no built-in vertical grip, but a separate vertical grip can be attached later for vertical shooting. In addition, the front cover of the Nikon Z8 is made of magnesium alloy, while the rear cover is made of the lightweight Sereebo®P series material. It features a 3.2-inch, 2,100,000-pixel screen with a maximum brightness of 900 cd/m2 and a four-way tilting design. The tilting operation is more efficient than that of a flip screen, allowing for quicker adjustment of the screen to a suitable angle for framing, whether shooting horizontally or vertically.
Nikon D750: Weighing 750g, the body is relatively lightweight. It adopts an integrated component structure shell design using carbon fiber composite materials and other materials. It is 10g lighter than the Nikon D610 despite having basically the same volume. The Nikon D750 is equipped with a 3.2-inch, approximately 1,230,000-pixel, flippable LCD screen. There are many buttons on the back, and a new “i” button is added on the left side of the body. Pressing this button allows for the modification of some commonly used parameters. The screen can be tilted upward to approximately 90° or downward to approximately 75°, enabling flexible adjustment of the viewing angle within a wide range, which is convenient for framing, especially for video shooting. However, the flip screen bracket on the back is a bit fragile and needs to be carefully protected.
Imaging Core
Nikon Z8: It adopts the same stacked full-frame CMOS sensor as the Nikon Z9, with approximately 45,710,000 effective pixels, and is equipped with the EXPEED 7 image processor. This enables the Nikon Z8 to excel in resolution, image quality, high ISO performance, and dynamic range. Its native ISO ranges from ISO 64 to ISO 25,600, and it still delivers excellent high ISO image quality at ISO 6400, with outstanding noise control and clear and complete detail presentation. There is no problem using ISO 12,800 even in extreme environments.
Nikon D750: The total pixel count is approximately 24,930,000, and the effective pixel count is approximately 24,320,000. It uses the EXPEED 4 processor. In terms of high ISO performance, the maximum usable ISO is approximately between 3,200 and 6,400. The autofocus performance is extremely good, and the high dynamic range performance is satisfactory, capable of meeting the needs of most daily shooting and professional photography.
Focusing System
Nikon Z8: It offers similar subject detection and autofocus performance as the Z9, capable of detecting nine types of objects, applicable in both photo and video modes. It can detect humans, dogs, cats, birds, cars, motorcycles, bicycles, trains, and airplanes, and an additional dedicated airplane detection mode has been added. Moreover, the Nikon Z8 supports autofocus at -9EV, allowing for autofocus operation even in dimly lit conditions or even under moonlight.
Nikon D750: It has a 51-point focusing system with 15 cross-type focus points and 11 sensors that support F/8 focusing. The focusing speed is average, but the autofocus performance is excellent, capable of meeting the focusing requirements in general shooting scenarios.
Continuous Shooting Capability
Nikon Z8: It performs excellently in continuous shooting. When only recording in JPEG format and using a high-speed memory card, it can achieve a high-speed continuous shooting rate of up to 120 frames per second. It can also perform continuous shooting at 60 frames per second and 30 frames per second. In JPEG + RAW format, it can achieve a high-speed continuous shooting rate of approximately 20 frames per second, and the continuous shooting endurance exceeds 1,000 frames.
Nikon D750: The continuous shooting function supports a maximum continuous shooting speed of approximately 8 frames per second, which can meet the continuous shooting needs in some daily shooting and specific scenarios, but there is a significant gap compared to the continuous shooting speed of the Nikon Z8.
Video Shooting
Nikon Z8: It has powerful video capabilities, capable of recording 4K60P videos for 125 minutes and 8K30P videos for approximately 90 minutes. It can also internally record 12-bit N-RAW and ProRes RAW HQ as well as 10-bit ProRes 422 HQ and H.265 videos. During shooting, its intelligent autofocus system can identify multiple shooting subjects and always lock the focus.
Nikon D750: It supports a video resolution of 1920×1080 and can shoot videos at frame rates such as 60P, 50P, 30P, 25P, 24P, etc., which can meet the general video shooting needs, but there is an obvious gap compared to the Nikon Z8 in terms of video resolution and frame rate.
Other Aspects
Nikon Z8: It has a built-in five-axis VR vibration reduction mechanism that supports body stabilization and works in synergy with the two-axis VR vibration reduction function of Nikkor Z-mount lenses to achieve a maximum stabilization compensation effect of approximately 6 stops. In addition, the Nikon Z8 is equipped with dual card slots, namely CFexpress and SD card slots. It also provides two USB Type-C interfaces, one for data transmission and the other for power supply, better meeting the needs of connecting to a computer for remote shooting or live streaming recording.
Nikon D750: It adopts a dual card slot design. Slot 2 can be used as additional space or backup storage space, or for separately storing images created using NEF + JPEG. It also supports copying photos between the two cards. It is the first model in Nikon’s full-frame camera lineup to incorporate Wi-Fi functionality, facilitating photo transfer and sharing with other devices.
