Nikon Coolpix S5100 vs Sony Cyber-shot DSC-HX9V: A Hands-On Comparison for Smart Buyers

When I first laid hands on the Nikon Coolpix S5100 and Sony Cyber-shot DSC-HX9V, both compact cameras seemed like solid candidates for casual shooters aiming for pocket-friendly but competent gear. Nearly a decade apart in release dates, these two small-sensor compacts carve out very different approaches despite somewhat overlapping ambitions - Nikon’s S5100 being a straightforward, no-frills compact, the Sony HX9V pushing the envelope with an extended zoom and more versatile features.

In this thorough comparison, I’ll bring you clear-headed insights based on my hands-on testing, digging deep into how these cameras hold up for various photography disciplines and photo/video needs today. Though neither is fresh off the shelf, they remain intriguing options for entry-level buyers mindful of budget and size. Let’s see which excels where - and who should buy which.

First Impressions: Size, Feel, and Handling

When considering compact cameras, size and ergonomics often tip the balance first, especially if you carry your camera everywhere or shoot street and travel often. The Nikon S5100 is a true basic compact - slim and lightweight at only 132g with dimensions measuring 97 x 57 x 22 mm. By contrast, the Sony HX9V, weighing 245g and measuring 105 x 59 x 34 mm, is almost double the bulk.

Handling-wise, the Nikon feels like a polished cheapskate gadget - simple textured plastics and no clubs for thumbs or fancy thumb grips. It’s minimalist with only the essential buttons and dials - not one for the manual enthusiasts. The Sony HX9V offers a firmer hand grip, slightly bigger buttons, and some manual controls (such as manual focus and exposure compensation), meaning it suits those wanting a bit more creative control without lugging a DSLR.

Viewed from the top, the Sony’s slightly chunkier controls do give it a more traditional "camera" feel - the ISO, zoom lever, and dedicated exposure compensation button are within easy reach, helping speed up adjustments during shooting.

For casual point-and-shoot use, the Nikon feels better pocketable. But if you want some control without going full DSLR, the Sony’s ergonomics serve you better in the hand.

Sensor and Image Quality: The Heart of the Matter

Let’s hit the technical core. Both cameras employ the same "1/2.3 inch" sensor size, but the sensor technology and processing gang differ considerably.

• Nikon S5100: A 12-megapixel CCD sensor paired with the Expeed C2 processor.
• Sony HX9V: A 16-megapixel backside illuminated CMOS (BSI-CMOS) sensor teamed with Sony’s BIONZ processor.

From years of testing compact cameras, I can tell you CCD sensors, though traditionally good for color rendition, usually falter under low light and lag behind CMOS sensors in speed and noise performance. The S5100’s max ISO is 1600, reflecting its modest low-light ambition. The HX9V extends ISO to 3200, allowing for better high ISO noise handling.

Resolution-wise, Sony’s 16MP edge gives more detail potential, especially noticeable when cropping or printing moderately large photos. In my testing, photos from the HX9V exhibited noticeably sharper details and cleaner shadows, thanks in part to the more modern sensor and processing.

In practice, landscape shots at ISO 100 look quite decent on the Nikon, with vibrant colors but slightly softer textures and more visible noise in shadows. The Sony takes a clear lead in dynamic range, retaining more detail in bright skies and shadowed areas - essential for landscape and outdoor shooters.

Display and Interface: What You See Is What You Get

Shooting experience ties closely to the rear display quality, especially when these cameras lack viewfinders.

The Nikon S5100 sports a modest 2.7-inch fixed LCD with just 230k-dot resolution. It’s serviceable outdoors only in shaded conditions and gets a bit grainy when bright sun hits it. The Sony HX9V impresses with a 3-inch, 921k-dot "XtraFine" LCD featuring TruBlack technology - a superior panel with deeper blacks and higher contrast, exceptionally useful when framing shots or reviewing images on the fly.

Neither camera has a touchscreen, which feels a bit dated by today's standards but was typical at the time. Sony’s interface is packed with more options, including customizable buttons and quick access to ISO, exposure compensation, and autofocus modes - a boon for those who want fast adjustments.

Autofocus and Shooting Speed

Autofocus systems on small sensor compacts are often basic, but their real-world usability can vary.

The Nikon S5100 uses a contrast-detection AF system with no face detection, no eye tracking, and no continuous AF during burst shooting. It only offers single AF & live view AF, meaning focus locks before the shot but can hunt a bit indoors or low light. Nok.

The Sony HX9V ups the ante with a contrast AF system that includes 9 focus points, multi-area AF, and face detection (though no eye detection). While not blazing fast compared to DSLRs, it tracked subjects better in daylight and mid-range light conditions. Its burst mode supports 10 frames per second, much faster than Nikon’s lack of burst capability (continuous shooting is not specified on Nikon).

Thus, for fast-moving subjects like kids or pets, Sony’s autofocus and burst system handled the pressure far better - a crucial consideration.

Lens and Zoom Range

Another major difference: zoom capabilities. The Nikon S5100 has a 28-140mm equivalent lens (5x zoom) with max aperture ranging F2.7-6.6 - reasonably bright upfront for compact standards but slower at the telephoto end.

Sony HX9V boasts a massive 24-384mm equivalent (16x zoom), starting at F3.3 at wide angle but narrowing to F5.9 at max zoom. This superzoom versatility is a game-changer for travelers or wildlife enthusiasts who need reach without switching lenses.

While the deeper zoom sacrifices some brightness and resolution at extremes, Sony’s Optical Image Stabilization cushions this with clearer shots at hand-held telephoto zooms.

Flash Performance and Low Light Capability

Both cameras feature built-in flashes but differ in nuances.

The Nikon includes versatile flash modes like auto, red-eye reduction, fill-in, and slow sync but only uses standard pop-up units with limited range. Sony’s flash performs comparably but adds slow sync and can reach about 4.0 meters, slightly better for indoor group shots.

But for low light photography beyond flash range, Sony’s higher sensitivity and better sensors give it a clear advantage. When I tested indoor shots with available light, HX9V images were brighter, more detailed, and with cleaner noise levels.

Video Capabilities

Even small compacts now offer video recording - so how do these two fare?

• Nikon S5100: Records video at up to 1280x720 pixels (HD) at 30fps in Motion JPEG format - simple, large file sizes, and no audio input.
• Sony HX9V: Delivers full Full HD 1920x1080 recording at 60fps (stunning for a compact), also supports AVCHD and MPEG-4 formats. No external mic input but has HDMI output for easy playback on TVs.

Sony’s video output is clearer, smoother, and more pleasing, making it a better pick for casual videographers or vloggers on the go.

Battery Life, Storage, and Connectivity

Pragmatic engineers and budget users often overlook battery life - a shame because it directly affects shooting pleasure.

The Nikon S5100 runs on the EN-EL10 battery; while exact CIPA rating isn’t stated here, my experience suggests about 200-250 shots per charge typical given the sensor and processing load. Sony uses NP-BG1 batteries, which rank better in stamina - often yielding up to 300-350 shots depending on usage.

Storage-wise, Nikon accepts SD/SDHC cards only, while Sony supports SD/SDHC/SDXC plus Memory Stick Duo variants - a versatile combo that echoes its more pro-leaning feature set.

Sony’s standout connectivity is a built-in GPS for geo-tagging, plus Eye-Fi card compatibility for wireless image transfer - features the Nikon completely lacks, keeping it firmly in the basic bracket.

Build Quality and Weather Sealing

Neither camera is weather-sealed or ruggedized. Build-wise, both rely mainly on plastic casings - the Sony feels chunkier and more robust, while Nikon prioritizes slimness and low weight over durability.

Hands-On Photography Discipline Breakdown

Let’s break down how these cameras stack up against common shooting styles, based on hours of practical testing.

Portrait Photography

• Nikon S5100: The bright wide aperture (F2.7) helps achieve some background separation but limited by the smaller sensor and fixed AF center without face detection. Skin tones come out natural but less refined.
• Sony HX9V: More pixels translate to sharper eyes and hair strands, with face detection improving focus precision. Though no eye AF, it does a better job locking onto faces, producing more pleasing portraits with smoother bokeh at medium focal lengths.

Landscape Photography

• Nikon's modest resolution and CCD sensor capture bright, colorful landscapes but with limited dynamic range and slight softness in detail.
• Sony’s 16MP BSI-CMOS sensor delivers richer detail and better highlight retention, making it preferable for rich landscape scenes.
