As a professional reviewer with over 15 years of evaluating digital cameras across genres, I’ve tested both extensively, measuring their performance, handling, and feature sets in realistic shooting conditions. This detailed comparison synthesizes technical analysis, real-world findings, and ergonomic insights to help you make an informed choice aligned with your photographic ambitions.

Understanding the Design and Ergonomics: Handling in Your Hands

Before even discussing image quality or features, the way a camera feels can significantly shape your shooting experience. The Canon SX510 HS and the Nikon P7800 diverge noticeably in size and grip design, reflecting different design philosophies.

The Canon SX510 HS is a compact superzoom model boasting a 30x optical zoom with a relatively large zoom barrel extending from a petite body. Measuring approximately 104 x 70 x 80 mm and weighing 349 grams, it is geared towards travel photography where long reach and lightness matter. However, the camera’s boxy silhouette and moderate grip do not cater ideally to prolonged handheld use, especially at heavier zoom lengths where holding stability becomes crucial.

In contrast, the Nikon Coolpix P7800, though slightly heavier at 399 grams, is more of a refined compact enthusiast camera with classic DSLR-inspired ergonomics in a smaller package measuring 119 x 78 x 50 mm. Its thicker grip and flatter profile provide superior handling comfort during extended shoots, particularly in manual shooting modes where stability is paramount.

Examining the top control layout reveals Nikon’s classic ring controls for aperture and shutter speed - features that delight users who prefer tactile dials for fine exposure adjustments, a rarity on compacts of its class. The Canon opts for simplicity, with fewer physical dials and reliance on menu navigation, which may slow down manual operation. These ergonomic distinctions reflect Canon’s focus on beginner friendliness versus Nikon’s appeal to manual exposure aficionados.

Sensor Technology and Image Quality: The Heart of the Camera

At the core of photographic performance lies the sensor. Both cameras utilize relatively small sensors compared to modern mirrorless or DSLR bodies but differ markedly in size and technology.

The Canon SX510 HS is equipped with a 1/2.3-inch CMOS sensor sized roughly 6.17 x 4.55 mm (28 mm²) with a resolution of 12 megapixels. While this sensor size supports the camera’s long 30x zoom, the downsized sensor area inherently limits dynamic range and low light sensitivity, making it less suited to demanding lighting conditions or large prints.

On the other hand, the Nikon P7800 sports a larger 1/1.7-inch backside-illuminated (BSI) CMOS sensor measuring 7.44 x 5.58 mm (41.5 mm²), also at 12 megapixels. The BSI structure improves photon absorption, leading to better noise control and dynamic range compared to traditional sensors of similar size. Nikon’s sensor thus delivers superior image quality, particularly under low-light conditions or scenes with high contrast.

Our real-world testing paralleled these inherent advantages; Nikon’s images exhibited cleaner shadows and better highlight retention when shooting indoors or twilight landscapes. Canon’s output appeared softer and noisier at ISO 800 or above, indicating the differentiation that sensor size and design bring to practical image quality.

Autofocus Performance and Shooting Speed: Capturing The Decisive Moment

For many shooters, autofocus (AF) speed and accuracy can make or break candid moments, wildlife shoots, or fast-action scenes.

The Canon SX510 HS’s AF system is contrast-detection based with just a single focus point - albeit with face-detection support in live view mode. This AF setup limits tracking capabilities and flexibility in composition but remains reliable for static subjects or leisurely shooting.

Conversely, Nikon’s P7800 features a sophisticated 99-point contrast-detection AF system enhancing subject tracking and focus precision, further bolstered by continuous AF support. Nikon also includes a face-detection feature, though disabled during live view stills by default, which aids portraitists significantly.

In burst mode, the SX510 HS shoots at 4 frames per second (fps), which suffices for casual sports or street photography but may lag behind rapid sequences. The P7800 doubles that speed to 8 fps, providing better coverage for wildlife and action sequences, although buffer depths are limited by the compact’s internal processing constraints.

Build Quality, Weather Resistance, and Durability: How Tough Are They?

Neither camera offers true environmental sealing or ruggedness, placing both squarely out of reach for extreme weather shooting without protection. Their plastic and metal chassis construction, though differing in feel, provide typical robustness for consumer compacts - solid enough for daily carry yet requiring care in harsh environments.

The P7800’s slightly heavier build and sturdier feel may inspire more confidence for outdoor shooting, while the SX510 HS’s lighter, plastic-heavy body favors portability. If you often shoot landscapes under inclement weather or travel in demanding conditions, complementing either with protective gear is advisable.

User Interface and Screen Quality: Your Window to Creativity

A camera’s rear screen quality and user interface design profoundly impact usability, especially for inexperienced users navigating menu systems.

The SX510 HS presents a 3-inch fixed TFT LCD with a modest 461k-dot resolution, adequate but not exceptionally sharp. The screen’s non-articulated design limits shooting angles, particularly when working at low or high viewpoints.

Nikon’s P7800 offers a 3-inch fully articulated LCD with a superior 921k-dot resolution, enabling versatile framing in challenging positions and improved image preview clarity. Moreover, the P7800 includes an electronic viewfinder (EVF) matching the main screen’s resolution and offering 100% coverage, which benefits outdoor shooting in bright conditions where LCD screens struggle.

While neither camera features touchscreen input, their button layouts reflect their ergonomic philosophies - Nikon’s is denser but organized with enthusiast control in mind, whereas Canon’s minimalistic interface aids beginners.

Lens Performance and Zoom Range: Flexibility versus Optical Quality

Lens specifications represent a significant divergence between these two cameras, reflecting priorities toward zoom reach or optical quality.

The Canon SX510 HS’s 24-720mm (35mm equivalent) lens is a staggering 30x zoom, one of the longest in fixed-lens compacts, making it a compelling choice for travel and wildlife enthusiasts seeking reach without carrying extra lenses. However, this extreme zoom range comes with compromises: maximum apertures range from f/3.4 at wide to f/5.8 at telephoto, which can limit low-light performance and depth-of-field control at longer focal lengths. Optical sharpness across the range shows visible softness and chromatic aberrations at extremes - a typical trait for superzooms.

In contrast, the Nikon P7800’s lens covers a more modest 28-200mm range (7.1x zoom), commensurate with traditional enthusiast compacts. Its brighter f/2.0–4.0 aperture range lets in significantly more light at the wide end, facilitating better background separation and low-light shooting. Lens sharpness is commendable across the zoom range, showing crisp center detail and controlled distortion.

Lens flexibility thus depends on your priorities: the SX510 HS excels in reach and versatility for distant subjects; the P7800 wins for wider apertures, optical quality, and shallow depth-of-field effects useful in portraits and low light.
