Nikon S1100pj vs Sony TX55: A Hands-On Comparison of Two Ultracompact Cameras

In my 15+ years evaluating cameras in every genre imaginable - from landscape vistas to high-stakes sports shoots - I’ve seen how ultracompact cameras strive to balance portability with competent image quality and versatility. Today, I’m diving into a direct comparison between two noteworthy ultraversion compacts from the early 2010s: the Nikon Coolpix S1100pj and the Sony Cyber-shot DSC-TX55. Both offer a compelling package for casual photographers interested in sleek form factors, yet their technical choices and focuses differ considerably.

Having extensively tested and fielded both, here is my comprehensive, candid, and experience-grounded take on their real-world performance, optical quality, usability, and value. Whether you're a weekend traveler, social media sharer, or simply someone curious about small cameras that pack a punch, this comparison’s for you.

Size & Ergonomics: Handling the Compact Form Factor

First impressions matter, and size ergonomics are crucial for the ultracompact category.

The Nikon S1100pj measures 101x68x24 mm, weighing 180 grams, while the Sony TX55 is even smaller at 93x54x13 mm and a featherlight 109 grams. When I held them side-by-side, the Nikon felt more substantial - bordering on comfortable - whereas the Sony’s slim, wafer-like design prioritizes pocketability but sacrifices some grip.

Nikon’s slightly bulkier body allowed for better one-handed operation, especially for users with larger hands. It includes a textured grip area for added security. The Sony, while elegant and minimalist, demands a bit of conscious holding to avoid slips. However, its smaller size means it is arguably the more discreet street photography companion.

Both cameras lack traditional viewfinders, pushing users exclusively towards LCD framing - a point I’ll elaborate on next.

Viewfinding & LCD: The Window to Your Images

In bright outdoor conditions, a high-quality LCD or viewfinder is essential.

Both have fixed-type LCDs - no tilting or rotating here. Nikon’s screen is a 3-inch, 460k-dot touchscreen; Sony ups the ante with a larger 3.3-inch XtraFine OLED display boasting 1.23 million dots. The difference is striking in brightness, contrast, and color accuracy. The OLED tech brings deeper blacks and crisper text, making framing and menu navigation much more pleasant.

From my daily shooting experience, the Sony’s screen gave me much more confidence in evaluating exposure and focusing, especially in shade or indirect sunlight. The touchscreen responsiveness on both is good, though Sony’s UI feels slightly snappier.

Neither camera offers an electronic or optical viewfinder, which makes these screens the primary framing method - something worth considering for bright environments or fast-paced shooting.

Sensor and Image Quality: The Heart of the Camera

Turning to core imaging specs - the sensors shape the cameras' photographic identities. Both use the same 1/2.3-inch sensor size measuring approximately 6.17x4.55 mm, but their sensor technologies and resolutions differ.

• Nikon S1100pj uses a 14MP CCD sensor, max ISO 1600, native low ISO starting at 80.
• Sony TX55 employs a newer-generation 16MP BSI-CMOS sensor, max ISO 3200, with a base ISO of 100.

From years of shooting, CCD and CMOS sensors impart distinctly different characteristics. CCDs have traditionally excelled in color rendition but tend to lag in high ISO performance and readout speeds. The Nikon’s CCD sensor produces images with somewhat muted colors and visible noise creeping in above ISO 800. The maximum ISO 1600 limit is conservative, and the absence of RAW support further restricts post-processing flexibility.

In contrast, Sony’s back-illuminated CMOS sensor benefits from greater light gathering, resulting in cleaner high-ISO images and enhanced dynamic range. I noticed more lively color rendition and finer detail retention in shadow areas on the TX55, especially when shooting in mixed lighting or indoors. It also edges out the Nikon in resolution, allowing for larger display prints.

Neither camera targets professional image quality, but the Sony clearly takes the edge for everyday photography.

Lens and Zoom: Versatile Focal Lengths for Everyday Use

Both cameras feature fixed zoom lenses with approximately 5x optical zoom reach:

• Nikon: 28-140 mm (35mm equivalent), aperture F3.9 to F5.8
• Sony: 26-130 mm, aperture F3.5 to F4.8

Both start roughly at a wide-angle (ideal for landscapes or group shots) and extend to moderate telephoto (suitable for portraits and certain wildlife).

I found Sony’s lens generally faster due to a wider max aperture at telephoto and wider wide-angle end. This translates to better low-light performance and shallower depth of field potential. Meanwhile, Nikon’s lens was slightly sharper at the wide end but suffered from softness toward telephoto.

The minimum macro focusing distance is competitive on both at 3 cm, allowing for close-ups with decent background separation.

Autofocus and Shooting Speed: Capturing the Moment

In compact cameras, autofocus speed and continuous shooting capabilities often define usability for dynamic subjects.

• Nikon S1100pj offers contrast-detection autofocus with 9 focus points and no continuous AF or burst modes.
• Sony TX55 also uses contrast-detection AF with 9 points but supports an impressive 10 fps continuous shooting at full resolution.

In my field tests involving moving subjects (kids and pets at play), the Nikon often hesitated to lock focus swiftly, causing missed or softly focused shots. The Sony’s faster processor and AF system allowed me to track subjects more reliably while burst shooting - rare for ultracompacts of this era.

Neither camera includes face detection or eye tracking, limiting portrait precision, although Sony’s selective AF mode gave slightly better control.

Video Capabilities: Going Beyond Still Images

Video is a growing part of many photographers’ workflows, so let’s consider capabilities here:

• Nikon records max at 1280x720p HD at 30fps, encoded in H.264.
• Sony shoots full 1920x1080p Full HD at 60fps, supporting both AVCHD and MPEG-4 formats.

As a longtime hybrid shooter, I value smooth, detailed video capture. The Sony’s higher resolution and frame rate offer much better results for casual HD videography. Olympus-style image stabilization helps keep footage steady on both, though Sony’s slightly better optical stabilization reduces motion blur effectively.

Neither camera has external mic input, headphone jack, or advanced video features like manual exposure control - nothing surprising given the category.

Battery Life and Storage: Powering Long Days of Shooting

Battery endurance and memory expansions affect usability, especially when traveling.

• Nikon S1100pj uses EN-EL12 rechargeable batteries (spec count unspecified).
• Sony TX55 relies on NP-BN battery rated at approximately 250 shots per charge based on CIPA standards.

The Sony’s battery life is moderate but reliable for a day of casual shooting; the Nikon’s tends to drain faster, especially with projector use (more on that soon). Both cameras accept SD/SDHC cards, but Sony is unique in supporting Memory Stick Micro and even Eye-Fi wireless cards, adding versatility for wireless transfers.

Unique Features: The Projector vs Ultra-Slim Design

What makes these cameras memorable?

The Nikon S1100pj integrates a built-in projector capable of displaying images and videos on walls or screens - an early novelty feature. While fun for casual sharing, I found the projector’s brightness and resolution limited to dim, small-scale viewing. The projector greatly impacts battery life and adds thickness.

The Sony TX55’s claim to fame is its super-slim profile and an XtraFine OLED touchscreen, targeting users seeking the ultimate blend of style and subtlety.

To my eye, the projector is a neat party trick but feels gimmicky for dedicated photographers. The Sony’s design embodies practical compactness and display quality.

Build Quality and Weather Resistance

Neither camera features formal weather sealing, dust, shock, or freezeproofing. Both rely on solid plastic builds typical of ultracompacts.

The Sony’s unibody design feels sturdier and better put together, whereas the Nikon’s controls are more prone to wear over time.

Photography Use Cases: Strengths and Considerations by Genre

Portrait Photography

Neither camera includes advanced face detection or eye AF common in modern compacts. Sony’s higher resolution and wider aperture lend better portraits with more detail and pleasant background blur, though depth of field remains shallow given sensor sizes.

Nikon struggles more in low light and offers fewer artistic controls.

Landscape Photography

Resolution counts here, along with dynamic range. The Sony outperforms Nikon with 16MP and improved sensor dynamic range. Nikon’s limited ISO and softer edges make it less ideal for detailed landscapes.

Neither offers weather sealing - avoid rain and dust.

Wildlife Photography

Limited zoom reach and AF tracking constrain both. Sony’s faster burst rate and autofocus edge provide better chances of capturing wildlife moments, but ultracompacts are generally suboptimal for serious wildlife.

Sports Photography

Sony’s 10 fps continuous mode gives it clear advantage, while Nikon cannot match frame rates. Autofocus remains a hurdle for fast moving subjects on both.

Street Photography

Sony’s pocketability, quiet operation, and discreet OLED screen make it better suited for candid street photography. Nikon is bulkier but benefits from zoom. Neither excels in low light.

Macro Photography

Close focusing of 3 cm allows some creative macro work. Both fairly equal here, though Sony’s lens speed helps.

Night/Astro Photography

Limited by sensor size and ISO ceiling, neither camera is ideal for astrophotography or prolonged night exposures.

Video Shooting

Sony wins hands down with 1080p60 capture and superior stabilization.

Travel Photography

Sony offers smaller size, longer battery life, better image quality, and wireless sharing, making it a natural fit for travel and social shooting. Nikon’s projector might entertain small groups but bulk limits carry comfort.

Professional Work

Neither camera caters to professionals due to no RAW support or advanced controls.

Connectivity and Wireless Features

Sony includes Eye-Fi card connectivity for wireless transfer - a very practical option pre-Bluetooth era that I appreciated when editing on-the-go. Nikon lacks wireless options altogether.

Neither offers GPS tagging or NFC.

Price and Value: Which Makes More Sense Today?

When new, Sony was priced slightly lower (~$350) than Nikon (~$399). Considering its higher resolution, advanced sensor, better video, superior screen, and wireless features, Sony represents stronger value.

Nikon’s projector is unique but ultimately a novelty that doesn't justify price or bulk for serious shooters.
