Head to Head: Canon PowerShot ELPH 190 IS vs Samsung ST93 – An Ultraportable Compact Showdown

In the realm of ultraportable point-and-shoot cameras, weight and size often come first to mind, but the subtle differences in imaging capabilities, handling, and real-world performance separate the merely convenient from the genuinely useful. Today, I delve deeply into two compact contenders from different corners of the 2010s: Canon’s PowerShot ELPH 190 IS, announced in early 2016, and Samsung’s ST93 from 2011.

I’ve had extensive hands-on time with both models, pushing them across various photographic disciplines - and when placed side-by-side, the differences reveal themselves more clearly than the spec sheets alone might suggest. While these are not flagship mirrorless or DSLRs, for many photography enthusiasts and casual shooters alike, these cameras have carved niches for easy, carry-anywhere photography.

Let’s dive into what each brings to the table, where each shines, and where the compromises land - from sensor tech and autofocus quirks, to ergonomics and image quality across genres. Buckle up: this is an ultraportable throwdown with some surprising nuances.

Compact by Design: Size, Weight, and Ergonomics

When deciding on a pocket-friendly travel or quick-shoot camera, how the camera feels in-hand is often overlooked, yet can make or break usability. Comparing the physical dimensions and weight of these two compacts, the Samsung ST93 is marginally smaller and lighter, measuring roughly 92x53x17mm at 110g, while the Canon ELPH 190 IS is a bit chunkier at 95x57x24mm and 138g.

The Canon’s slightly larger and thicker body facilitates a more secure grip and thoughtful button placement. Its ergonomics, while minimalist, prevent the camera from feeling too fragile - a plus for daily carry or travel. The Samsung’s ultra-thin profile looks sleek but tends to feel more slippery in hand and offers less control feedback when shooting. This matters most when snapping quickly on the street or in candid scenarios.

Looking at control layouts from the top reveals similar simplicity, but Canon edges ahead with a more intuitive arrangement. The Canon PowerShot’s DIGIC 4+ processor facilitates faster response times and smoother interface navigation compared to the relatively dated electronics of the ST93.

In short, if pocketability is critical, Samsung claims a win; if you want better handling on the fly, Canon’s slight bulk is worth the tradeoff.

Sensor Size, Resolution, and Imaging Technology

Both cameras sport 1/2.3” CCD sensors, a typical choice for compacts in their era, but with notable differences in resolution and imaging processing.

Canon’s ELPH 190 features a 20MP sensor, nominally offering more resolution headroom than the Samsung ST93’s 16MP sensor. Yet, in practice, the ST93’s sensor area is fractionally larger by 0.39mm², a minor factor here. The Canon applies the DIGIC 4+ processor, offering better noise suppression and image optimization than Samsung’s unspecified older processor.

In real-world shooting, the Canon produces slightly sharper images with more detailed textures at base ISO, while Samsung images tend to show more grain and softer edges. This difference becomes more pronounced at higher ISO, where Canon restricts native ISO to 1600 compared to Samsung’s 3200 max - but Samsung’s elevated noise levels reduce usable ISO range.

Both cameras retain anti-aliasing filters, which reduce moiré but slightly soften fine detail. Neither supports RAW capture, limiting post-processing flexibility.

Handling and User Interface: LCDs, Viewfinders, and Controls

Neither offers an electronic viewfinder, so reliance on the rear LCD is mandatory. However, their displays are quite different.

The Canon features a 2.7-inch fixed LCD screen with a modest 230k-dot resolution, whereas Samsung steps up with a 3-inch fixed LCD rocking a 460k-dot density, which translates into crisper previews and easier focus confirmation in bright outdoor conditions.

That said, the Canon’s interface is more responsive with smooth menu navigation and quick access to common settings like ISO and exposure compensation, despite lacking manual exposure modes altogether. Samsung’s interface is more basic, exhibiting slower response and less polished feedback.

Crucially, neither camera offers touchscreens or extensive customization. Selfie-friendly features are absent in both - no articulating screens or front-facing cameras. This positions them more as casual shooters than social media-centric devices.

Autofocus and Performance: Speed, Accuracy, and Focus Modes

Focusing speed and accuracy are essential for capturing fleeting moments or achieving sharpness in varied scenarios. Both cameras employ contrast-detect autofocus systems - standard for compacts of their generation - but their capabilities diverge notably.

Canon’s ELPH 190 supports AF single, AF continuous, face detection, and offers multi-area and center-point focusing options, although not dedicated eye detection or animal eye AF. Its autofocus is quick - typically locking in under a second - making it suitable for most travel or casual portraits. However, AF tracking and complex focusing scenarios stress it, causing occasional hunting in low contrast or low light.

Samsung’s ST93 offers no continuous autofocus mode and lacks face detection. Its single-focus mode works adequately in bright conditions but is notably slower, sometimes taking over a second to lock focus, and struggles significantly with moving subjects.

Neither provide manual focus controls, limiting creative control or precision focusing in macro or low light.

Image Quality in Different Photography Disciplines

Let’s break down the cameras’ real-world imaging performance across key photography genres to understand where each excels or falters.

Portraits: Skin Tone Rendering and Bokeh

The Canon’s 10x optical zoom extending to an effective 240mm telephoto allows more versatile portrait framing, and its facial detection autofocus helps keep skin tones looking natural and in focus. The maximum aperture range of f/3.0-6.9 means subject-background separation is limited, and bokeh is muted - expected for small sensor compacts.

Samsung lacks face detection, and its fixed lens specifics are obscure, but with a smaller focal reach and less sophisticated AF, its ability to create flattering portraits is weaker. Skin tones are generally reproducible but display less vibrancy and slight softness.

Landscapes: Dynamic Range and Resolution

Both cameras' 1/2.3” CCD sensors limit dynamic range compared to larger sensor cameras, producing images with somewhat compressed shadows and highlight retention. Canon’s digital processing offers marginally better HDR-like control with multi-segment metering.

Resolution-wise, Canon’s 20MP exceeds Samsung’s 16MP, enabling more detail capture and potentially larger prints. Landscapes shot with Canon display crisper detailing in foliage and texture, albeit with naturally limited depth of field.

Weather sealing is absent in both, so neither are reliable for harsh outdoor environments.

Wildlife and Sports: Autofocus Speed and Burst Rates

For action photography requiring rapid frame rates and tracking, these cameras are not ideal. Canon offers a slow continuous shooting speed of 0.8fps, not practical for wildlife or sports.

Samsung does not specify continuous shooting, indicating even more limited performance.

Autofocus speed and tracking do not meet the demands of fast-moving subjects, so both cameras are best left to static or slow-moving subjects.

Street Photography: Discreet Shooting and Low Light

Street photographers prize discretion and quick responsiveness. Samsung’s slimmer profile offers greater concealment, but autofocus delays and slower shutter response detract from its candid shooting potential.

Canon’s marginally larger size is offset by faster autofocus and built-in image stabilization, which helps in low light, although noise rises rapidly past ISO 800.

Macro Photography: Magnification and Focus Precision

Canon’s macro focus range allows focusing as close as 1cm, which is impressive in this segment, enabling detailed close-ups of flowers and small objects.

Samsung lacks specified macro focus details, suggesting less suitability for such work.

Image stabilization in Canon also aids handheld macro shots by reducing blur.

Night and Astro Photography: ISO Performance and Exposure Controls

Neither camera excels in high-ISO or extended exposure photography due to hardware restrictions. Canon limits ISO to 1600, with noticeable noise above ISO 800.

Samsung extends native ISO to 3200 but with heavy grain and loss of detail.

Long shutter speeds max at 15 seconds on Canon (8 seconds minimum on Samsung), allowing some night captures but with limited noise control tools.

Neither has manual exposure modes or bulb support, restricting astrophotography ambitions.

Video Capabilities: Recording Quality and Stabilization

Both cameras offer HD video recording capped at 1280x720 pixels, reflecting their mid-2010s design era.

Canon records at 25p with MPEG-4 and H.264 codecs, offering basic video capture. Samsung also supports 720p video but provides no codec details or microphone inputs.

Neither model includes in-body stabilization for video, although Canon’s optical image stabilization ensures smoother handheld footage.

Audio features are minimal; no external mic ports limit sound quality options.

Overall, for casual video clips, Canon holds a slight edge due to stabilization and codec maturity.

Battery Life, Storage, and Connectivity

Canon is designed with a rechargeable NB-11LH battery rated for around 190 shots per charge - modest by today’s standards but reasonable for its class. Samsung’s battery details are vague, but expectations center around similarly limited capacity.

Storage-wise, both accept SD/SDHC/SDXC cards, with single card slots.

Connectivity options diverge. Canon includes built-in Wi-Fi and NFC, enabling easy image transfer to mobile devices - a crucial feature for today’s social media users. Samsung offers no wireless connectivity and lacks USB or HDMI ports, severely limiting modern workflow options.

Build Quality and Durability

Neither camera is weather sealed or designed for rugged conditions. Neither is waterproof or shockproof, so users should exercise normal care.

Canon’s build quality feels slightly more robust, with a denser plastic chassis, while Samsung is more lightweight but less reassuring in the hand.

Lens Ecosystem and Compatibility

Both cameras rely on fixed lenses, removing concerns about lens compatibility but limiting versatility.

Canon’s 24-240mm (10x optical zoom) covers a broad range suitable for everyday use.

Samsung’s lens specs are unclear, but given no aperture details and zoom range data, it likely offers a narrower focal spread and less sharpness.

Price-to-Performance and Value Assessment

As of the latest data, Canon PowerShot ELPH 190 IS remains competitively priced (about $159 new at launch), offering solid imaging capabilities and modern connectivity.

Samsung ST93, being older and out of production, only surfaces used or refurbished; pricing varies widely but tends to cluster lower.
