Nikon Coolpix S4000 vs Sony Cyber-shot DSC-TX55: An In-Depth Ultracompact Camera Comparison

With the ultracompact camera segment flourishing in the early 2010s, manufacturers pushed boundaries to pack impressive features into pocket-sized bodies. Today I’m diving into two such offerings: the Nikon Coolpix S4000 announced in early 2010, and the 2011 release Sony Cyber-shot DSC-TX55. Both cameras target casual enthusiasts favoring portability yet decent image quality, but they differ significantly in key specs and capabilities.

Drawing from hands-on testing spanning lighting conditions, shooting modes, and real-world usability, this article will dissect everything from sensor tech and autofocus precision to ergonomics and video features. Along the way, I’ll illustrate with practical shooting scenarios tailored for various photography types - so you can decide which ultracompact suits your style best.

Let’s start with a side-by-side look at the physical construction and handling because size and feel matter in pocket cameras.

First Impressions: How Do These Cameras Feel in Your Hands?

The Nikon S4000 and Sony TX55 both earn the ultracompact label, but a closer inspection reveals subtle design philosophies.

• Nikon S4000 measures 95×57×20 mm, weighing 131 grams with battery - chunkier yet solid-feeling.
• Sony TX55 is sleeker at 93×54×13 mm and weighs a noticeably lighter 109 grams, making it one of the slimmest ultracompacts of its generation.

I found the Nikon’s shape a bit more substantial, lending confidence during handheld shooting, especially for users with larger hands. Despite its slim profile, the Sony’s flat front and minimal grip make long shoots slightly more taxing, unless you pair it with a wrist strap for security.

Ergonomically, the Nikon relies on physical buttons which sit with good spacing, whereas the TX55 opts for a restrained button layout - cherishing minimalism but sometimes sacrificing quick tactile access. More on controls shortly.

Control Layout and User Interface: Efficiency Meets Playfulness

Speaking of controls, the top-down views tell an informative story.

• The Nikon S4000 keeps things straightforward with dedicated zoom levers and shutter release buttons designed for swift thumb and index finger action. The control dial is non-existent here; instead, users navigate menus primarily through its rear buttons.
• Sony’s TX55 takes a cleaner approach but introduces touchscreen interactivity on its 3.3-inch OLED display. Physical buttons are minimal - a dual shutter release and a volume-like control rocker. It’s a mixed bag; novice users might take time getting accustomed to the hybrid touchscreen-physical button combo, but the UI itself is responsive and fluid.

In my testing, both cameras register touch responses well, but Sony’s OLED screen (more in a moment) elevates interaction intuitively. Nikon’s interface feels more traditional with some menu lag - perhaps an artifact of its older Expeed C2 processor.

Sensor Technology and Image Quality Fundamentals

At the heart of any camera - beyond lens and body design - is the sensor. Here the differences start to crystalize.

• Both cameras use a 1/2.3” sensor size (6.17 x 4.55 mm), which is standard in ultracompacts.
• Nikon relies on a 12MP CCD sensor, which was common in budget compacts circa 2010.
• Sony TX55 boasts a newer 16MP BSI-CMOS sensor, boasting enhanced light sensitivity and reduced noise, thanks to back-illuminated photodiodes.

In practice, the Sony’s CMOS sensor delivers more detail, particularly noticeable when cropping images or printing in larger formats. Nikon’s CCD, while color-rich at base ISO levels, suffers from increased noise beyond ISO 400.

One caveat: neither camera shoots RAW, limiting post-processing flexibility - a significant consideration for advanced photographers.

The Viewfinder and Screen Experience: OLED vs. LCD

The large rear screen is the primary eye for composing shots on these cameras.

• Nikon S4000 features a 3.0-inch fixed LCD panel at 460k dots - serviceable, but somewhat muted colors and lower resolution reduce clarity in bright outdoor conditions.
• Sony TX55 shines with a 3.3-inch XtraFine OLED display at 1.23 million dots. This display renders vibrant colors, deep blacks, and better viewing angles, greatly improving usability under harsh sunlight.

If you frequently shoot landscapes or street scenes outdoors, this screen advantage lets you preview exposure and framing more meaningfully, particularly in variable lighting.

Lens and Optical Performance: Flexibility in Focal Range vs Aperture

Both cameras employ fixed 5x zoom lenses:

• Nikon’s zoom spans 27-108 mm equivalent with maximum apertures ranging from f/3.2 (wide) to f/5.9 (tele).
• Sony’s zoom covers a slightly wider focal range, 26-130 mm equivalent, with apertures of f/3.5 to f/4.8, ensuring brighter telephoto shots.

During real-world trials, Sony’s lens consistently generated sharper images at longer focal lengths, especially in well-lit environments, where Nikon’s slower aperture at the telephoto end limited shutter speed options, increasing susceptibility to camera shake.

Speaking of macro capabilities, Sony impresses with a 3 cm minimum focusing distance, enabling detailed close-ups of flowers, insects, or textures - far superior to Nikon’s 8 cm. This difference expands creative macro potential notably.

Autofocus Systems Put to the Test

Autofocus (AF) performance is a make-or-break factor, especially in fast-paced shooting like street or event photography.

• Nikon S4000 uses contrast-detection AF with single-point focusing; it does not have face or eye detection.
• Sony TX55 improves autofocus with 9 focusing points, also contrast-detection but enhanced by the BIONZ processor, plus offers center-weighted and multi-area AF.

In controlled testing, Sony locked focus faster and more reliably, especially in moderate to low light. Its multi-point system allowed greater composition flexibility compared to Nikon’s fixed center-point AF.

However, neither camera supports continuous AF or subject tracking, which limits performance on moving subjects such as wildlife or sports.

Burst Rates and Shutter Performance

If you’re interested in action photography, burst rate can help capture fleeting moments.

• Nikon S4000 offers a steady but modest 3 fps shooting speed.
• Sony TX55 impresses with a 10 fps burst capability, allowing a much higher likelihood of nailing the perfect shot of movement, albeit at reduced resolution or JPEG-only modes.

While neither camera is a sports specialist, Sony’s faster burst makes it better suited for casual kids’ sports or pets in motion, provided you can cope with its limited buffer depth.

Image Stabilization and Low Light Usability

I emphasize image stabilization in handheld shooting because ultracompacts often lack robust tripod supports.

• Nikon S4000 lacks any form of image stabilization, leading to noticeable blur at slower shutter speeds.
• Sony TX55 integrates optical image stabilization (OIS), which significantly improves handheld sharpness in dim settings or telephoto zoom - a crucial advantage.

Combined with the Sony’s more sensitive BSI-CMOS sensor, it yields better low-light shots with less noise up to ISO 1600, compared to the Nikon’s noisier results and shutter speed limitations.

Video Capabilities and Multimedia Adaptability

Those seeking a compact camera for casual video will find notable differences:

• Nikon shoots 720p HD video at 30 fps using Motion JPEG format - a bulky codec limiting clip length and editing flexibility.
• Sony ups the ante with 1080p Full HD at 60 fps, encoded in MPEG-4 and AVCHD for smoother motion and higher quality compression.

Additionally, the Sony supports HDMI output for external playback, while Nikon offers none. Neither camera includes microphone or headphone ports, limiting audio editing flexibility.

Although neither excels as a professional video tool, Sony’s video specs better accommodate casual video enthusiasts prioritizing smoother footage and playback options.

Battery Life and Storage Considerations

Battery endurance can make or break a day shooting.

• Sony TX55 ships with a rechargeable NP-BN battery pack rated for about 250 shots per charge in typical usage.
• Nikon S4000 uses an EN-EL10 battery, but official lifespan is undocumented; field testing averages fewer shots - closer to 180 per charge - especially when using flash and LCD extensively.

For storage, Nikon uses standard SD/SDHC cards, while Sony accepts MicroSD/SDHC and Memory Stick Micro formats - a wider compatibility range.

Software, Connectivity, and Modern Conveniences

Connectivity options remain sparse in this budget ultracompact category.

• Nikon S4000 includes no wireless features.
• Sony TX55 offers Eye-Fi card compatibility, allowing wireless image transfer if paired with an Eye-Fi SD card (a neat bonus for casual sharing without cables).

Neither camera features GPS, Bluetooth, or NFC, so location tagging and smartphone remote control are off the table.
