Samsung PL170 vs Sony Cyber-shot TX55: An Ultracompact Camera Showdown from 2011

When diving back into the early 2010s ultracompact camera market, these two models often surface for comparison: Samsung’s PL170 and Sony’s Cyber-shot TX55. Both dedicated to everyday snapshots, pocket-friendly travel, and casual photography, they occupy a similar niche, yet differ significantly in capability and user experience. Over my years testing cameras, I’ve always approached these compact cameras with a focus on practical use - how the hardware and software team up to serve real-world photographers, not just a spec sheet showdown.

Given you may be researching these models as budget options or nostalgic pickups, let’s break down their strengths and compromises across pure photography use cases, technical performance, and overall value. I’ll weave in hands-on insights and detailed analysis, supplemented by carefully chosen visuals to help you visualize their design and output differences. Ready? Let’s get started.

A Tale of Two Ultracompacts: Design and Ergonomics at a Glance

Right out of the gate, both cameras are designed to slip easily into a pocket or purse, roughly sizing up as typical travel-friendly ultra compacts. But subtle differences in form factor and handling have meaningful impacts on daily shooting comfort and intuitiveness.

The Samsung PL170 shows its age in the slightly chunkier 95 × 57 × 19 mm build, built with practicality over panache in mind. Its 3-inch fixed LCD is modest at 230k dots - not exactly a feast for the eyes when you scrutinize photos on the fly. The camera lacks a viewfinder entirely, which wasn’t uncommon then but limits composition options in bright sunny conditions.

Conversely, the Sony TX55 is a sleeker, more refined package at 93 × 54 × 13 mm with a beautifully sharp 3.3-inch XtraFine OLED touchscreen boasting 1230k dots resolution. This difference makes reviewing images and navigating menus a pure joy. With on-screen manual focus controls and touchscreen operation, you gain a level of interactivity missing on the PL170. That said, neither camera includes an EVF, so you’re tethered to LCD framing entirely.

Control layouts also hint at usability: the Sony’s buttons are intuitively placed but minimalistic to keep the slim profile, whereas Samsung leans more traditional, yet both lack dedicated dials for exposure modes - a sign they’re aimed at casual point-and-shoot users.

Sensor Technology and Image Quality: The Heartbeat of Your Shots

Let’s dive below the surface to the image sensors - a decisive factor for image quality. Both use a 1/2.3-inch format sensor with 16 megapixels max resolution, but their sensor types and processing tackle image creation very differently.

Samsung’s PL170 is outfitted with an older CCD sensor, a staple in compact cameras pre-2010. CCDs historically offered vivid colors and low noise at base ISOs, but they generally struggle with noise control in low-light scenarios and lack the speed of modern sensors.

Sony’s TX55, on the other hand, features a BSI-CMOS sensor - the “Backside Illuminated” design gives it a signal edge by improving light gathering efficiency. This translates to cleaner images at higher ISO settings and more dynamic range, despite sharing the same sensor size and resolution.

In practice, when I tested both cameras in well-lit conditions, the image detail was surprisingly close - both deliver respectable sharpness across the 4608x3456 pixel images. But switch to indoor or low-light scenes, and Sony’s TX55 demonstrated cleaner shadows and better color fidelity. The PL170’s images were noticeably noisier and softer under the same settings (max ISO 3200 for both, but image usability differs).

Autofocus and Shooting Responsiveness: Not Just About Speed

Ultracompacts aren’t speed demons, but autofocus reliability and snappiness still dictate how much you enjoy shooting spontaneous moments or moving subjects.

Samsung’s PL170 offers no manual focus, nor does it have continuous or face detection autofocus. It uses contrast detection with a basic center-weighted AF area - but it’s quite slow and prone to hunting in complex lighting. I found the PL170 struggles especially in macro and low-light scenes, missing focus frequently or locking onto background elements.

Sony made notable strides here: the TX55 supports manual focus plus a contrast-detection AF system with 9 focus points and multi-area AF capability, providing improved precision. Face detection is absent but the AF speed feels brisker and more reliable in my hands, especially when shooting up-close macro subjects at its minimum 3cm focusing distance.

Both cameras lack sophisticated tracking AF for wildlife or sports, but the Sony’s ability to shoot at a 10 FPS burst mode offers a definite advantage for faster subjects, compared to Samsung’s lack of continuous shooting. That frames per second capability is a standout for its class, making Sony a better option when you want some action shots.

Display and User Interface: How You Interact With Your Images Matters

A premium shooting experience doesn’t end with the sensor - it’s about how comfortably you frame, review, and adjust your shots.

The TX55’s 3.3-inch XtraFine OLED touchscreen with 1230k pixels provides stunning clarity and color, surpassing the PL170’s fixed 3-inch LCD and 230k pixel resolution by a large margin. The touchscreen offers intuitive AF point selection and menu navigation, which I found much appreciated in daylight and low-light alike.

Samsung’s fixed display feels dated and slowly responsive, making manual operations less fluid and reviewing images far less pleasant. Both cameras lack viewfinders, so you'll be staring at these screens constantly.

Flash and Low Light Performance: How They Cope When the Sun Sets

Flash capabilities and low-light performance play a heavy role in usability, especially if you shoot indoors or out after dusk.

PL170 packs a tiny built-in flash with no external flash support, and the flash range isn’t specified, but it’s generally limited. Its CCD sensor’s lower high-ISO tolerance means you’ll be relying more on flash for acceptable exposures, or battling noise when going natural-light.

Sony’s TX55 includes a built-in flash with a 3.7-meter range and offers multiple flash modes (Auto, On, Off, Slow Sync), plus customizable white balance and bracketing to help balance scenes better. Coupled with its optical image stabilization, the TX55 can squeeze more handheld sharpness in lower light, even without flash.

Video Capabilities: Stepping Into Motion

Though both cameras hail from an era when video wasn’t the headline feature, the differences in recording system are notable.

PL170 caps video at 1280x720 HD resolution with no stabilizer. The lack of external mic ports and absence of image stabilization means shaky, noisy, and somewhat limited video quality even in short clips.

Sony TX55 pushes the envelope with Full HD 1080p recording at 60 FPS, alongside AVCHD and MPEG-4 formats - a boon for hobbyists wanting crisp motion capture. Crucially, Sony’s optical image stabilization helps produce smoother footage, compensating for handheld shake noticeably.

Battery Life and Storage: Longevity and Convenience on the Go

While neither model sets records here, Sony’s TX55 uses the modern NP-BN lithium-ion battery, rated officially for 250 shots per charge. The Samsung’s battery life details are unclear, but from experience with era CCD compacts, you can expect fewer shots per charge, especially with LCD use.

Both have single card slots, supporting SD storage. Sony can handle microSD, SDHC, and Memory Stick Micro formats, offering more flexible media options.

Real-World Photography Tests: How They Perform Across Genres

I’m often asked about specific applications. Let’s see how these cameras fit into different photography disciplines:

Portrait Photography

Both cameras struggle with advanced autofocus for eye detection or face recognition, offering no dedicated portrait modes. However, the Sony’s sharper sensor readout and manual focus aid capture of pleasing skin tones with less noise in moderate light. Samsung’s softer contrast and slower AF produce less reliable results.

Landscape Photography

Neither camera features weather sealing, limiting outdoor reliability in adverse environments. Resolution-wise, 16 MP delivers satisfying prints up to A3, but the Sony’s sensor yields cleaner dynamic range for shadow detail. Neither is ideal for wide-angle enthusiasts, but Sony’s 26mm equivalent wide end is slightly better suited.

Wildlife and Sports Photography

No camera here meets the needs of serious wildlife or sports shooters. However, Sony’s 10 FPS burst lets you get closer to action shots, while Samsung’s sluggish AF and no continuous shooting hold you back. Telephoto reach is roughly 5x for both but optical quality and AF speed favor Sony.

Street Photography

Both are small and discreet enough, but I prefer the Sony’s silent autofocus, touchscreen quick operation, and superior LCD for on-the-fly adjustments. The PL170 feels clunkier and slower, detracting from spontaneous shooting.

Macro Photography

Sony’s 3cm minimum focus improves on Samsung’s unspecified macro focusing abilities, coupled with manual focus options and steadier handheld shooting (due to OIS). The PL170 simply cannot compete here.

Night and Astro Photography

Both cameras fall short for astrophotography - small sensors, limited ISO performance, and shutter speed maxing at around 2 seconds on Samsung and shorter on Sony limit long exposures. Still, the Sony’s better noise control offers a slight edge.

Video

Sony’s Full HD 60p videos with stabilization crush Samsung’s 720p limited output. For casual video enthusiasts, TX55 is the clear winner.

Travel Photography

Compact and lightweight, both are easy carry. Sony’s better battery life, superior screen, faster AF, and video features make it a more versatile travel partner.

Professional Work

Neither is suitable for professional work requiring RAW capture or advanced workflow options. Sony’s better image quality justifies using TX55 as a backup camera in an amateur context.

Both cameras feature fixed lenses; no interchangeable options exist. Samsung’s specs do not list a focal range, but effective zoom multiplier stands at 5.9x. Sony’s 26–130mm equivalent zoom with f/3.5–4.8 aperture range is clearly stated, giving more framing flexibility.

While neither offers a lens ecosystem, Sony offers far more flexibility internally with macro mode and manual focus override.

Connectivity and Extras

A notable difference: Sony supports Eye-Fi wireless card connectivity and HDMI output, enabling easy image transfer and TV connection. Samsung PL170 has no USB, HDMI, or wireless.

Build Quality and Environmental Resistance

Neither model features weather sealing or ruggedized protection. Samsung’s larger body may feel slightly clumsier but presumably more durable, while Sony’s slim metal body is elegant but delicate.

Pricing and Value: Then and Now

At launch, Samsung’s PL170 was priced around $175, targeting budget-conscious buyers. Sony’s TX55 entered the market at roughly double, $350, reflecting its more advanced features and premium build.

If investing today as a vintage or entry-level compact, Sony’s TX55 offers superior image quality, ergonomics, and versatility, justifying its price premium.
