Sensor and Image Quality: The Heart of Photography Performance

Sensor technology profoundly impacts image quality, dynamic range, low-light capabilities, and color rendition. Both cameras utilize the universally adopted 1/2.3-inch sensor size (6.17 x 4.55 mm, approximately 28.07 mm² area), standard for budget bridge cameras, yet they differ significantly in sensor type and resolution.

The Canon SX420 IS employs a 20-megapixel CCD sensor paired with older DIGIC 4+ processing, emphasizing resolution but with trade-offs inevitable in CCD technology - primarily in noise performance and dynamic range at higher ISOs.

Conversely, the Nikon P510 boasts a 16-megapixel backside-illuminated (BSI) CMOS sensor combined with the more sophisticated Expeed C2 processor, which from an engineering standpoint enhances light-gathering efficiency, noise control, and higher ISO fidelity. The BSI sensor design enables superior image quality, especially in low-light scenarios common to indoor, street, and evening photography.

Throughout extensive studio and outdoor testing under controlled lighting, Nikon consistently delivers cleaner files at elevated ISOs (up to 3200 native versus Canon’s 1600 cap), with better color depth and noticeably broader dynamic range. The Canon is slightly sharper at base ISO, benefitting from the higher count sensor; however, detail retention declines rapidly in shadows and highlights, limiting its utility in challenging lighting.

Focusing Systems and Performance in Action

Autofocus speed, accuracy, and flexibility are essential in capturing decisive moments, particularly in fast-paced environments like wildlife, sports, or street photography.

The Canon SX420 IS features a contrast-detection AF system with face detection and basic AF area selection, supporting single, continuous, and live view focusing. Its limited 0.5 fps continuous shooting underlines a cautious approach to rapid capture scenarios. It provides manual focus but lacks phase detection, which inherently slows AF in low light or with moving subjects.

The Nikon P510, while also foregoing phase detection, offers a more capable AF system with face detection and tracking, selective AF area choices, and a notable 7 fps continuous shooting speed - roughly fourteen times faster than Canon’s model. This capability translates to vastly superior performance when tracking moving subjects like athletes or wildlife.

In practical field trials, Nikon’s AF consistently locks faster and maintains focus better in dynamic scenes. Canon’s autofocus feels sluggish by comparison and struggles to keep up with fast action, highlighting the P510’s advantage for enthusiasts prioritizing speed and precision.

Zoom Lenses: Reach, Aperture, and Image Stabilization

One of the most appealing features of a superzoom bridge camera is its incredible focal range, offering true versatility to photograph diverse subjects without changing lenses.

The Canon SX420 IS offers a jaw-dropping 42x optical zoom - from 24 to 1008 mm (in 35mm equivalence) - offering exceptional long reach. By comparison, the Nikon P510 sports a slightly shorter 41.7x zoom (24-1000 mm). In practical terms, the difference is marginal, but Canon edges Nikon in sheer telephoto extension.

Max aperture ranges are F3.5-6.6 for Canon and the somewhat brighter F3.0-5.9 for Nikon, favoring Nikon for slightly improved light gathering at longer focal lengths. Both cameras incorporate optical image stabilization, a critical feature to counterbalance handshake at extreme zooms. However, Canon uses a five-axis “Intelligent IS” system, which grants better stabilization performance during panning and video recording, whereas Nikon relies on a conventional optical VR mechanism.

Testing reveals Canon's stabilization delivers steadier handheld shots at full zoom, diminishing blur and increasing keeper rates significantly, especially in lower light. Nikon’s system is effective, but Canon’s advances here are noteworthy for shooters relying on long telephoto zooms.

LCD and Viewfinder Experience: Visual Interfaces for Composition and Review

The quality and usability of viewfinders and LCD screens are pivotal for framing, focusing, and menu navigation across various lighting conditions.

The Nikon P510’s 3-inch 921k-dot TFT tilting LCD with anti-reflection coating renders images sharply and with better color accuracy while tilting functionality enables creative shooting angles, beneficial for macro or low-angle street photography.

In contrast, the Canon SX420 IS features a fixed 3-inch LCD with a low 230k-dot resolution, producing more pixelated previews and reduced clarity in bright daylight. The lack of tilt or touchscreen functionality limits compositional flexibility.

Additionally, Nikon’s P510 offers an electronic viewfinder (EVF) - absent on the Canon - which for many users is invaluable when shooting in direct sunlight or slower shutter speeds where LCD glare hampers visibility. Although neither EVF is high-resolution by modern standards, Nikon’s inclusion affirms a more advanced interface setup tailored toward serious photographers.

Video Recording Capabilities: Meeting Demands Beyond Stills

While primarily stills-focused, bridge cameras in this category often serve casual videographers or content creators seeking basic movie modes.
