Sensor and Image Quality: The Quantum Leap

At the heart of any DSLR’s capability is its sensor, directly influencing resolution, dynamic range, ISO performance, and color fidelity.

Technical Insights:
The D780's full-frame BSI-CMOS sensor represents a significant leap in sensor technology and size compared to the APS-C CMOS found in the D90. The Back-Side Illuminated (BSI) design on the D780 enhances light gathering capability, reducing noise at higher ISOs - a critical advantage for low-light, night, and astro photography. The larger sensor surface area means improved depth of field control, superior dynamic range, and better color rendition.

In direct real-world testing, the D780 delivers cleaner images at ISO 3200 and above, maintaining color integrity and shadow detail far more effectively than the D90, which experiences noticeable noise and color degradation beyond ISO 1600.

The D90’s sensor resolutely served its era by producing sharp images with color fidelity suitable for most general photography applications. However, its resolution and low-light scalability fall short of modern standards, limiting usability in demanding environments.

Autofocus System: Precision and Speed in Varied Conditions

Effective autofocus (AF) performance underpins successful shooting across most photography genres.

The D780 incorporates a sophisticated 51-point AF system featuring 15 cross-type sensors, enabling more reliable subject detection, tracking, and precision focusing - crucial in fast-paced scenarios like sports and wildlife photography. Its hybrid AF system in live view yields swift and accurate focusing by blending phase-detect with contrast-detect methods.

The D90’s 11-point AF system, while effective for its launch period, lacks advanced tracking capabilities and cross-type precision, limiting accurate subject acquisition, especially for moving objects. Its live view AF is contrast-detection-only, slower, and less reliable.

In practice, the D780 excels in sustained autofocus tracking during burst shooting, and its eye detection AF significantly improves portrait sharpness, especially with moving subjects. The D90 requires more manual AF intervention in complex scenes.

Shooting Performance: Burst Rates and Shutter Capabilities

Performance-based technical attributes - frame rate, shutter speeds, buffer size - augment or limit creative flexibility and suitability across genres.

The D780's faster maximum shutter and higher frame rate are advantageous in capturing fleeting moments in sports and wildlife photography. Though neither camera offers a true silent (electronic) shutter, the faster mechanical shutter on the D780 introduces flexibility in bright light and high-speed action.

The D90’s more limited shutter speed and slower burst rate constrain its suitability for fast-moving subjects but suffice for landscape, portrait, and casual shooting.

Video Capabilities: From Basic to 4K Support

Video functionality has become integral even to primarily stills-focused DSLRs.

While the Nikon D90 introduced video recording to Nikon DSLRs, it offers only 720p resolution and limited codec options, constraining video quality and editing flexibility. The absence of external microphone input and headphone jack restricts professional audio monitoring.

Conversely, the Nikon D780 is fully contemporary in video terms, offering 4K UHD recording at up to 30fps with solid codec choices. It supports external audio devices via microphone and headphone ports, enabling professional on-set monitoring and postproduction workflows. The availability of 1080p slow-motion at 120fps adds creative videography options.

Photographers valuing hybrid stills/video capabilities will find the D780 notably superior.

Display and User Interface: Touch and Tilt Versus Fixed

Usability and compositional flexibility in live view and playback modes benefit significantly from display specifications and touch responsiveness.
