Nikon Coolpix S4000 vs Sony Cyber-shot DSC-TX66: A Hands-On Ultracompact Camera Showdown

Having spent well over fifteen years testing cameras under diverse lighting, motion, and environmental conditions, I find the ultracompact category fascinating: it’s where the trade-offs between size, speed, and image quality are most palpable. Today, I’m diving deeply into two popular compact cameras from the early 2010s: the Nikon Coolpix S4000 and the Sony Cyber-shot DSC-TX66. Both aimed at casual photographers craving pocketable convenience paired with respectable imaging, yet they approach the ultracompact space with distinct philosophies and technologies.

Drawing on multiple shooting sessions in real-world scenarios spanning portraits, landscapes, street scenes, and travel, plus detailed tech analysis, I’ll help you understand which camera suits your creative goals and how these devices hold up nearly a decade after their release. I’ll also accompany this review with plenty of image examples and side-by-side comparisons to illustrate practical differences.

Let’s begin with the physical design before tearing into core imaging performance and usability.

Size and Ergonomics: Pocket-Friendly, but Which Feels Better in Hand?

When handling ultracompacts like these, ergonomics and control layouts strongly influence your shooting experience - especially during extended sessions.

The Nikon S4000 weighs about 131 grams with dimensions of 95x57x20 mm. The Sony TX66 is notably lighter and slimmer, weighing just 109 grams at 93x54x13 mm. I was instantly struck by how the TX66’s sleek, ultra-thin body practically disappears in the palm. It fits comfortably in a jacket pocket with hardly any bulk, making it a superb choice for those who prioritize absolute portability.

Yet, Nokia’s coolpix S4000 offers a chunkier build that some may find more reassuring, especially if you like a solid grip - it felt less “slippery” to me in colder weather when my fingers got numb. The S4000’s tapering front lens block and textured rear aid stability, whereas the TX66’s smooth glass front and minimalist top put more emphasis on style over grip.

Both have fixed lenses with a power zoom controlled by a toggle ring - though the TX66’s lens extends more noticeably with its 5x zoom, compared to the S4000’s 4x zoom range. So in terms of sheer handling, if pocketability edges your priority, Sony wins. But if you want firmer grip and a somewhat traditional compact feel, Nikon offers a more confident hold.

Control Layouts and Interface

Let’s zoom in on how each camera organizes its physical buttons and menus. A good control scheme can greatly accelerate shooting.

Both lack dedicated dials for aperture or shutter priority modes (these entry-level ultracompact cameras omit manual controls), yet the Nikon's buttons are somewhat larger and better spaced. The S4000’s shutter release and zoom toggle feel more tactile. Its small but fixed 3-inch LCD (with 460k-dot resolution) handles framing and menu navigation decently but shows some lag navigating menus under sunlight.

Sony’s TX66 trades some button size for a cleaner appearance. Its touch-sensitive effects include zoom and shutter controls buried in the touchscreen menus, which take some getting used to but are responsive once you master them. The 3.3-inch OLED screen shines bright with a crisp 1230k-dot resolution, making it easier to track focus and preview images vividly in outdoor shooting scenarios.

For me, the TX66’s UI feels more modern and engaging but requires patience to become efficient. Nikon’s approach is straightforward, better aligned for quick-point-and-shoot sessions.

Sensor and Image Quality: The Heart of the Matter

Both cameras share the same physical sensor size: 1/2.3-inch (6.17 x 4.55 mm), which measures roughly 28 mm² of surface area. However, sensor technology and resolution differ considerably.

The Nikon S4000 uses a 12MP CCD sensor coupled with the Expeed C2 processor, while Sony’s TX66 employs an 18MP back-illuminated CMOS sensor with the BIONZ processing engine. This difference has a significant impact on image quality.

Resolution and Detail

The Sony’s 18MP sensor naturally delivers higher resolution images (nearly 5k x 3.6k pixels) compared to Nikon’s 12MP at 4k x 3k pixels. When pixel-peeping, I noticed the TX66’s photos exhibit crisper details and retain fine textures better - especially in good lighting and at base ISO.

Noise and High ISO

More than resolution, the sensor technology matters for noise handling. The TX66’s BSI-CMOS sensor design reduces noise in low-light conditions sharply compared to Nikon’s older CCD sensor. Shots taken indoors or at dusk showed the TX66 maintaining cleaner skies and skin tones with less grain at ISO 800 and above. The S4000 images showed more noise and degraded colors in shadows.

Dynamic Range

While exact scientific DxO Mark scores are unavailable for these cameras, my side-by-side exposure tests demonstrated Sony’s sensor preserves more highlight and shadow detail without clipping, thanks to CMOS sensor improvements and more advanced image processing.

Color Reproduction

Both cameras are decent at color rendition in natural light. Nikon’s colors tended to be slightly warmer and more neutral, while Sony leaned cooler with a bit more saturation - preferable for vibrant greens and blues.

In summary, from a purely image quality standpoint, the Sony wins hands down - especially for those who want sharper, cleaner images in varied lighting. Nikon is more limited by older sensor technology, but still capable of decent photos in bright daylight.

LCD and Live View Experience

Ultracompact shooters rely heavily on rear LCDs in place of viewfinders when composing shots and reviewing images.

Sony’s TX66 features a 3.3-inch Xtra Fine TruBlack OLED display with 1230k dots - noticeably superior to the Nikon’s 3-inch 460k dot LCD. The OLED screen delivers punchy contrast, deep blacks, and wider viewing angles. It felt comfortable framing street scenes and portraits without any noticeable glare, even outdoors.

The S4000’s LCD is more modest, with less dynamic range and reduced resolution. Also, it lacks touchscreen controls beyond basic menu navigation, while the TX66 supports touch zoom, focus selection, and effects - a big usability plus for fast action.

Live view autofocus mechanisms also vary. The Nikon uses contrast detection autofocus with single shot only - slow to lock focus and prone to hunting in low contrast. The Sony implements contrast detection AF enhanced with touch AF areas and face detection, translating to quicker, more consistent focusing in most conditions.

Autofocus and Shooting Speed

Given these are ultracompacts without manual exposure controls, autofocus accuracy and burst shooting often define practical versatility.

Nikon S4000’s contrast-detection AF can be sluggish, especially indoors or in low light. It supports single autofocus only - no continuous tracking or face detection. Burst mode tops out at 3 fps, which is modest and not well suited for fast-moving subjects.

The Sony TX66 shines in autofocus technology, featuring contrast detection AF supplemented by face detection and touch AF areas. While it lacks phase-detection AF found in higher-end models, its algorithms perform impressively for an ultracompact. It also supports autofocus tracking and selective AF area modes, allowing greater control over focus priority.

Burst shooting clocks in at 10 fps, more than triple the Nikon’s rate, making the TX66 more aplomb at capturing fleeting moments - a boon when photographing kids or pets.

Lens Flexibility and Macro Performance

Both cameras come with fixed zoom lenses tied to their bodies - a common design in ultracompacts. Here is how they compare:

• Nikon S4000: 27-108mm equivalent (4x zoom), maximum aperture f/3.2-5.9
• Sony TX66: 26-130mm equivalent (5x zoom), maximum aperture f/3.5-4.8

The Sony not only offers a longer zoom range but also faster apertures at the telephoto end, beneficial for low-light telephoto and background blur.

Macro Capabilities

Sony’s lens offers an extraordinary minimum focusing distance of 1 cm, enabling captivating close-up shots with impressive detail and bokeh separation. Nikon’s minimum focus distance is 8 cm, decent but less impressive for macro enthusiasts.

In my experience, the TX66’s macro mode enabled me to capture sharp textures on flower petals and insect details with ease, while the S4000 struggled to get equally close and sharp without resorting to digital cropping.

Video Capabilities: HD Quality for Memories

If video is in your ultracompact checklist, the Sony TX66 provides a clear advantage with full HD 1080p recording at 60 fps in AVCHD and MPEG-4 formats, paired with built-in optical image stabilization (OIS).

The Nikon S4000 maxes out at 720p at 30 fps in Motion JPEG format, which is clunkier and heavier in post-processing. Its lack of any image stabilization results in jittery handheld footage.

Although neither camera supports external microphones, the TX66’s smoother footage and better frame rates contributed to noticeably more watchable clips - an important differentiator when preserving personal moments or casual vlogging.

Battery Life and Storage

Battery endurance is critical for travel and street photographers who cannot afford frequent recharge breaks.

The Sony TX66 offers a rated 250 shots per charge using the NP-BN battery pack, which aligns with typical ultracompact endurance. In practice, I routinely squeezed a half-day outing with moderate LCD usage and video clips.

The Nikon S4000 uses EN-EL10 batteries, reputedly less long-lasting, although official shot counts vary and are undocumented here. My time with the S4000 revealed the need to carry extras for extended shoots.

On memory, both support SD/SDHC cards - Sony adds compatibility with Memory Stick Duo formats and microSD, providing broader flexibility for card preferences.

Connectivity and Extras

Neither camera offers Wi-Fi, Bluetooth, or GPS, which limits cloud sharing or instant geo-tagging - unsurprising for their release dates when such features were less common.

Sony includes an HDMI output for easy playback on TVs, beneficial for reviewing images with family or clients. Nikon lacks HDMI, relying solely on USB 2.0.

Sony’s TX66 also supports White Balance bracketing and offers some creative shooting modes, enhancing versatility in tricky lighting.

Durability and Environmental Resistance

Neither camera is weather-sealed, waterproof, or shockproof, standard for budget ultracompacts. Those seeking ruggedness would require different categories.

Real-World Photography Performance Across Disciplines

I put both cameras through their paces covering common photography genres:

Portraits

Sony’s face detection and eye-detection accuracy made portraits sharper, with attractive skin tone reproduction and pleasing bokeh from its 130mm reach and wider aperture. Nikon’s limited focusing slowed workflow and rendered flatter bokeh with less separation.

Landscapes

Landscape shooting favors resolution and dynamic range. Sony’s 18MP sensor captured more detail in foliage and skies, while the Nikon’s images occasionally clipped highlights under harsh midday sun due to narrower dynamic range.

Wildlife & Sports

Neither camera is ideal here given small sensor and slow AF systems. That said, Sony’s 10 fps burst and tracking AF performed moderately better for capturing playful dogs and birds in nearby park scenes. Nikon struggled with focus lock and slower frame rates.

Street

Sony’s compact form, quick AF, and silent shutter (to some degree) gave it an edge for discreet candid shots. Nikon's louder shutter and slower AF made it less suited for fast street shooting.

Macro

Sony’s 1 cm macro focus range allowed creative close-ups with definition and natural blur. Nikon lagged behind, restraining framing options.

Night and Astro

Low light shooting significantly benefited from Sony’s superior noise handling at ISO 800+, a necessity for casual night cityscapes. Nikon’s images at night were noisy and less detailed.

Video

Sony’s full HD 60 fps, OIS, and smooth focusing stood out. Nikon’s video was serviceable for home movies but had jitter and reduced resolution.

Travel

The Sony’s light weight, extended zoom, superior LCD, and better battery favored travelers wanting a “one and done” pocketable camera.

Professional Work

Neither camera offers RAW capture or manual exposure controls, limiting professional usability. Nikon’s JPEG-only output and slower workflow constrain serious applications, while Sony’s modest enhancements offer a bit more flexibility.

Image Gallery - Seeing Is Believing

To truly grasp differences, I captured a series of images with both cameras under identical conditions.
