Yes, the Nikon Z7 and D850 utilize practically the same high-performance 45.7-megapixel backlit (BSI) sensor, contributing to their exceptional image quality.
Both cameras feature a full-frame 45.7MP BSI CMOS sensor, a design choice by Nikon that ensures consistent, high-resolution imaging across its top-tier DSLR and mirrorless lines. This shared sensor technology is a significant factor in their similar photographic capabilities.
Sensor Performance and Shared Excellence
The common sensor design between these models, including the Z7's successor, the Z7ii, delivers outstanding performance metrics. For instance, sensor tests have indicated remarkable scores, with both the D850 and Z7ii sensors scoring 100 out of 100 on DXOMark, highlighting their top-tier performance in:
- Dynamic Range: Ability to capture a wide range of tones from deep shadows to bright highlights.
- Color Depth: Capacity to record a vast number of colors, resulting in rich and nuanced images.
- Low-Light ISO Performance: Producing clean images even at higher ISO settings, crucial for challenging lighting conditions.
This consistent sensor performance means photographers can expect excellent detail, color accuracy, and low-light capability from both the D850 and Z7, despite their different camera architectures.
Key Camera Differences
While the sensor is largely identical, it's important to note that the cameras themselves vary significantly in design and functionality, impacting the overall shooting experience.
| Feature | Nikon D850 (DSLR) | Nikon Z7 (Mirrorless) | Nikon Z7ii (Mirrorless) |
|---|---|---|---|
| Sensor Type | 45.7MP Full-Frame BSI CMOS | 45.7MP Full-Frame BSI CMOS | 45.7MP Full-Frame BSI CMOS |
| Camera Type | Digital Single-Lens Reflex (DSLR) | Mirrorless | Mirrorless |
| Lens Mount | Nikon F-mount | Nikon Z-mount | Nikon Z-mount |
| Image Processor(s) | EXPEED 5 | EXPEED 6 | Dual EXPEED 6 |
| Autofocus System | Dedicated DSLR AF module (153-point) | Hybrid AF (493-point on sensor) | Hybrid AF (493-point on sensor) |
| In-Body Stabilization | No (lens-based VR) | Yes (5-axis IBIS) | Yes (5-axis IBIS) |
| Viewfinder | Optical | Electronic (EVF) | Electronic (EVF) |
The transition from the D850's DSLR platform to the Z7's mirrorless design introduces benefits like in-body image stabilization (IBIS), a more compact form factor, and a shorter flange distance that allows for new lens designs. The Z7ii further refines the Z7 with dual processors for improved speed and expanded buffer capacity, but the core imaging sensor remains the same foundational component across all three models.
