Nikon P7800 vs Sony W730: A Hands-On Comparison of Two Compact Cameras for Enthusiasts

When it comes to choosing a compact camera that balances portability, image quality, and versatility, the field is crowded. Today, I’m diving deep into two models that often come up in such conversations: the Nikon Coolpix P7800 and the Sony Cyber-shot DSC-W730. Both hail from the small sensor compact segment and launched in 2013 within months of each other, yet they serve very different user profiles with their design, feature sets, and handling characteristics.

Having personally logged hundreds of hours testing various compacts - shooting landscapes, portraits, wildlife, street scenes, and more - I’ll guide you through a detailed comparison based on my practical experience. I’ll delve into their technical aspects, real-world performance, and suitability for diverse photographic genres, so you can find out which well-renowned model aligns best with your needs and shooting style.

Getting Hands-On: Size, Ergonomics, and Handling

Before even taking a shot, how a camera feels in your hands and fits into your routine is crucial. The Nikon P7800 is a mid-sized compact that leans more towards enthusiasts wanting traditional manual controls with a bit more heft. The Sony W730, by contrast, fits squarely into the ultra-portable “point and shoot” category, prioritizing lightweight convenience.

The Nikon P7800 measures 119 x 78 x 50mm and weighs in at about 399 grams with battery and memory card - noticeably larger and heavier than the Sony W730, which tips the scales at a mere 122 grams and measures just 93 x 52 x 22mm. This difference becomes immediately tangible when carrying the cameras out for a long day of shooting or travel.

Ergonomically, the P7800 benefits from a more substantial grip and a well-laid-out button array for accessing manual controls quickly. My fingers found the response tactile and intuitive, especially when changing aperture, shutter speed, or ISO settings on the fly.

In contrast, the Sony W730 is far more pocketable but compromises on control granularity. Its slick plastic body and smaller size make it great for slipping into a coat pocket, but the limited physical controls and smaller screen size can occasionally slow down operation during active shoots.

User Interface and Control Layout: Directness vs Simplicity

Ergonomics contribute to the shooting experience, but the interface itself dictates how quickly you can make adjustments or respond to changing scenes. The Nikon P7800 boasts a fully articulated 3-inch screen with 921k-dot resolution, complemented by an electronic viewfinder of the same resolution. It lacks touchscreen functionality but compensates with dedicated buttons and dials that seasoned photographers appreciate.

Meanwhile, Sony’s W730 sticks to a fixed 2.7-inch touchscreen display with a modest 230k-dot resolution - no electronic viewfinder here. Its touchscreen does allow for point-and-tap autofocus and menu navigation, which can be handy for novices but less precise for photographers used to physical shutter and dial feedback.

From my testing, the Nikon’s more advanced control scheme allows photographers to operate efficiently under pressure or challenging lighting. The Sony’s approach aims for simplicity but tends to feel limiting when trying to dial in specific settings swiftly.

Sensor, Image Quality, and Technical Foundations

At the core of any camera’s image performance is the sensor, its size, resolution, and technology. The Nikon P7800 features a 1/1.7-inch BSI-CMOS sensor with approximately 12 megapixels. Its sensor area is roughly 41.5 mm², larger than most compacts in its class, allowing for improved noise performance and dynamic range.

In comparison, the Sony W730 uses a smaller 1/2.3-inch CCD sensor at 16 megapixels, with a sensor area of about 28.1 mm². While the higher pixel count might sound appealing on paper, the smaller sensor size typically results in higher noise at elevated ISO settings and reduced performance in low light.

To understand the practical impact, I ran both cameras through my standard image quality evaluation protocol under various lighting conditions:

• In daylight, the Nikon delivers cleaner, sharper images with richer color depth and better dynamic range, thanks primarily to its newer BSI-CMOS technology and larger photosites.
• The Sony images appear softer and show increased noise beyond ISO 400, a limitation stemming from its smaller CCD sensor technology common in earlier compact models.

DxOMark scores for the Nikon P7800 reinforce this - a respectable overall rating of 54, with a color depth of 21.2 bits and dynamic range of 11.7 EV stops - parameters that bode well for enthusiasts wanting quality JPEGs and attractive raw processing flexibility.

The Sony W730 lacks official DxOMark data, but anecdotal evidence and test shots confirm its sensor performance would fall behind, particularly in terms of low light usability and shadow recovery.

Autofocus and Focusing Capabilities

Neither of these cameras sports a phase-detection system; instead, both rely on contrast-detection autofocus. Still, the Nikon P7800 shines here with its 99 focus points, face detection, and continuous AF tracking capabilities. It supports single-shot, continuous AF, and face detection modes, though it lacks wildlife or animal eye AF - which is understandable given its core market and era.

Sony’s W730 offers fewer AF points, no continuous AF option, and no sophisticated tracking, reflecting its simpler autofocus design aimed at casual users. However, it does incorporate touchscreen AF, which can be a convenient way to focus on subjects in certain shooting scenarios.

In real-world shooting, I found the Nikon’s autofocus noticeably quicker and more accurate, especially when tracking moving subjects such as children at play or street performers. The Sony often hesitated and struggled to lock focus in low contrast or low light situations.

Lens and Zoom Range: Versatility and Optical Quality

Both cameras have fixed zoom lenses. The Nikon P7800 sports a 28-200mm equivalent zoom with a bright aperture range of f/2.0-4.0, while the Sony W730 offers a longer 25-224mm reach but with a slower aperture of f/3.3-6.3.

The P7800’s lens stands out with a wider maximum aperture at the short end, providing better low-light capabilities and improved subject separation for portraiture, thanks to more natural background blur (bokeh). My portrait shots using the P7800 benefited from this, with appealing skin tone rendition and softly blurred backgrounds especially noticeable at 50-85mm equivalents.

Sony’s slower aperture means it requires more light or higher ISOs, which amplifies noise issues as previously discussed. However, its slightly longer zoom does afford greater reach for casual wildlife or travel photography, though detail retention suffers due to sensor constraints.

Shooting Experience Across Photography Genres

Let's explore how each camera performs in specific photographic disciplines. This practical breakdown reflects my hands-on shooting and testing, highlighting strengths and tradeoffs.

Portrait Photography

Portraiture relies on skin tone accuracy, eye detection, and bokeh quality. The Nikon P7800’s large sensor and bright lens aperture give it an edge here. Eye detection works reasonably well, and the P7800’s 99-point AF system allows for precise focus on facial features.

The Sony W730’s slower lens and smaller sensor translate to flatter portraits lacking creamy background separation. Eye detection is present but less reliable, and images tend to feel less three-dimensional.

Landscape Photography

Wide dynamic range and resolution are paramount in landscapes. The Nikon’s 12MP sensor delivers large, finely detailed files that hold up well to cropping. Its dynamic range allows retention of highlight and shadow details in scenes with contrast, such as sunrise over hills or forested valleys.

The Sony’s increased megapixels help achieve higher pixel count out of the box, but the smaller sensor area reduces tonal gradation. Its fixed screen size and no articulating display make composing tricky at odd angles during field shoots.

Though neither camera has advanced weather sealing, the Nikon’s more robust build and better battery life grant it some advantage for extended outdoor sessions.

Wildlife and Sports Photography

Neither camera is designed as a specialist for wildlife or sports, but in moderate use, the Nikon’s faster burst rate of 8 fps and more advanced AF tracking provide a functional benefit. The Sony manages just 1 fps, limiting its capacity for capturing action sequences.

Telephoto reach favors Sony slightly but at a notable cost in image quality and focus speed. For fleeting fast-moving subjects, the Nikon’s response and buffer capacity are much more satisfactory.

Street and Travel Photography

The Sony W730’s size, stealth, and quick touchscreen AF make it an attractive travel companion for casual street photography, especially for everyday snapshots where discretion is key.

The Nikon, while bulkier, rewards deliberate shooting styles with superior image quality and manual controls. Its longer battery life also supports longer outings.

I personally find the Nikon too large for comfortable everyday carry, so tradeoffs between quality and portability arise here.

Macro, Night, and Video Performance

Macro Photography

Both cameras enable close focusing to about 5 cm. The Nikon’s brighter aperture and image stabilization aid in capturing sharper macro shots handheld.

Sony’s fixed lens and lower resolution screen hamper focusing precision, though it offers touchscreen AF, which sometimes helps nail the focus spot.

Night and Astro Photography

The Nikon P7800 offers a native maximum ISO of 1600 (boosted to 6400), while Sony extends to 3200 max. However, noise and detail retention heavily favor the Nikon’s BSI-CMOS sensor, proving far better for low-light and night photography in my testing.

Additionally, Nikon’s longer maximum shutter speed of 60 seconds and built-in timelapse support give it a leg up for creative night and astro shooters.

Video Capabilities

The Nikon P7800 records full HD 1080p video at 30 fps, with support for microphone input, granting better audio control. It also includes slow-motion modes at lower resolutions (up to 120 fps in 640x480).

The Sony W730 limits video to HD (720p) at 30 fps, lacks microphone input, and has no advanced video features.

For photographers who want hybrid photo/video flexibility with higher quality, the Nikon holds a clear advantage.

Build Quality, Durability, and Battery Life

Neither camera offers weather sealing or ruggedized protection, so both require care in harsh conditions. The Nikon’s slightly more robust, heftier build includes a comfortable grip and solid metal accents that inspire confidence.

Battery endurance also favors the Nikon P7800, rated at ~350 shots per charge compared to Sony’s modest ~240. My real-world tests aligned well, with the Nikon remaining powered longer during extended shoots.

Connectivity, Storage, and Workflow Integration

The Nikon provides HDMI output and optional GPS and wireless modules (sold separately), enhancing its integration into professional workflows. USB 2.0 support allows tethered transfers, though slower by modern standards.

Sony lacks wireless or HDMI options but supports a wider range of memory cards including SD and Memory Stick formats, giving greater flexibility to those invested in its ecosystem.

How They Stack Up in Performance and Specialty Use

Performance metrics paint a consistent picture: the P7800 scores well across most photographic criteria, while the W730 remains a basic tool highly dependent on good lighting and static subjects.
