Casio EX-Z35 vs Samsung ST93: Hands-On Comparison of Two Ultracompact Cameras

When you’re in the market for an ultracompact camera, your priorities generally orbit convenience, ease of use, and image quality within a tiny, pocketable package. Today, I’m diving deep into two ultracompact models that flew somewhat under the radar but merit a thorough look for anyone interested in straightforward point-and-shoot options: the Casio EX-Z35 and the Samsung ST93. Released roughly a year apart (2010 vs 2011), these rivals try to cram decent specs into impressively small bodies while aiming for versatility in casual photography.

Having tested both extensively across multiple scenarios, I’ll walk you through what each camera does well, where compromises show, and who should consider either model based on how you shoot. Let’s unpack their strengths and weaknesses not just on paper but through hands-on experience and technical analysis.

Size, Handling, and Ergonomics: Pocket Pleasure or Fidgety Miniature?

Ultracompacts not only compete on specs but also on sheer pocket-friendliness and a user interface that doesn’t make you want to pull your hair out. Comparing the Casio EX-Z35 and Samsung ST93 physically reveals interesting design choices that affect comfort and usability.

Both cameras carry the expected small form factor, but the EX-Z35 feels a bit chunkier at 99 x 57 x 20 mm, whereas the ST93 shrinks it further to 92 x 53 x 17 mm, tipping the scales lighter (124g vs 110g). My hands, which are moderately sized, found the Casio’s slight girth more reassuring for steady shots. The Samsung is impressively slim - for travel and street photography where stealth and minimal bulk matter, that will appeal.

That said, Casio packs in a decent grip ridge on the front, helping you hold the camera more securely, while the Samsung’s smooth metal finish prioritizes stylishness but sacrifices grip a bit. If you tend to fumble small cameras, the EX-Z35 might win the battle of ergonomics.

Design and Control Layout: Smart Simplicity or Spartan Minimalism?

Control usability is often the silent dealbreaker in ultracompacts. You want quick access to commonly used features without navigating labyrinthine menus. Here’s what I noted when placing both cameras side-by-side.

The Casio EX-Z35 features a simple button cluster complemented by a 4-way directional pad, all clearly labeled and tactile, which makes manual white balance tweaks and self-timer controls accessible on the fly. The Samsung ST93 takes an even more pared-down approach, with fewer dedicated buttons and heavier dependence on on-screen menus, which can slow you down in candid shooting.

Neither camera offers manual exposure modes, which is typical at this level, but Casio’s inclusion of a custom white balance option slightly raises its appeal for white balancing challenges in mixed lighting - something I often contend with during indoor party shoots.

Neither has touchscreen functionality or any illuminated buttons for night-time operation, so both rely on fairly basic, traditional controls.

Sensor and Image Quality: Crunching the Numbers Behind the Pixels

Let’s take a close look under the hood where image-making magic begins: the sensor and processor combination. Though neither camera pushes groundbreaking boundaries for 2024 standards, understanding their hardware nuances helps set realistic expectations.

Both cameras sport 1/2.3-inch CCD sensors, but their resolutions differ: Casio’s sensor produces a 12 MP output (4000 x 3000), while Samsung ups that to 16 MP (4608 x 3456). On paper, Samsung’s higher pixel count could mean more detail, but there are trade-offs. The slightly smaller pixel size on the ST93 leads to more noise at higher ISOs and somewhat softer low-light results.

Casio integrates its mature Exilim Engine 5.0 image processor, honed over several generations, optimizing noise reduction and color rendition. Samsung lacks detailed processor info but doesn’t feel quite as refined in color rendering from my tests.

Dynamic range for both isn’t record-breaking - shadows crush, and bright highlights clip easily under harsh contrast - but the Casio handles midtones and skin tones with more natural rendition and less oversaturation. Samsung’s images sometimes err toward cool colorcast (common in CCDs without strong color calibration). Neither camera supports RAW capture, so you’re committed to straight JPEGs, limiting post-processing flexibility.

Low-light performance is modest on both, maxing out around ISO 3200 with visible grain. The EX-Z35’s slightly better noise control helps preserve detail at ISO 800-1600.

Screen and Interface: How You See Your Shot Matters

An often overlooked but crucial detail is the LCD - the window through which we compose and review shots daily.

The Samsung ST93 leads here with a larger 3.0-inch screen boasting a 460k-dot resolution, delivering sharper and brighter live view. The Casio EX-Z35’s smaller 2.5-inch screen with a modest 230k-dot resolution feels dim and grainy, especially under bright daylight conditions. This affects framing accuracy and reviewing images on the go.

Neither camera offers an electronic viewfinder - a habitual limitation for ultracompacts - so accurate composition heavily depends on screen clarity.

Interface-wise, Casio’s menus have a logical, minimalistic hierarchy, easing navigation for beginners. Samsung’s interface feels slightly dated and more menu-dense, which could slow down quick adjustments.

Autofocus and Shooting Experience: Quick and Reliable or Missed Moments?

AF performance is a key factor, especially if you shoot spontaneous moments in street or wildlife photography.

Both models rely exclusively on contrast-detection autofocus systems, which, by 2010-11 standards, is expected but noticeably slower than modern hybrid phase-detection AF. Neither supports face detection or eye AF, which feels archaic today.

Casio offers single AF with manual focus assistance - useful if you want to fine-tune focus in macro or portrait shots. Samsung’s autofocus lacks manual override, limiting creative control.

Neither model supports continuous autofocus or burst shooting, so action shooters beware: quick-moving subjects may frustrate you.

Moreover, Casio’s minimum shutter speed is 1/4 second longer (max 1/2000s vs 1/2000s on Samsung), but both provide similar exposure ranges for general use.

Portrait Photography: Skin Tones and Bokeh on a Budget

When it comes to portraiture, the dreaded ultracompact challenge is controlling depth of field and rendering natural skin tones.

Given the small sensors and relatively slow lenses, achieving creamy bokeh is tough on both cameras. The Casio EX-Z35 features a lens with a focal length range of 36-107 mm equivalent and max apertures of f/3.1-5.6, allowing some background separation at the telephoto end, but not dramatically so.

Samsung sadly does not provide focal range or aperture specs, but with a similar sensor size and lack of full manual controls, portraits tend to be flat with little background blur.

Without face or eye detection AF, accuracy requires steady hands and good lighting conditions. Casio’s custom white balance helps deliver skin tones closer to natural warmth, while Samsung’s cooler cast requires tweaking post-capture.

In practice, neither excels at headshot portraiture, but Casio has a slight edge for everyday snapshots.

Landscape Photography: Resolving Detail and Handling Contrast

Landscape demands demanding sensor capability and shooting stability.

Both cameras produce images with reasonable resolution - 16 MP on Samsung and 12 MP on Casio - but the larger megapixel count on Samsung doesn't fully translate to significantly sharper landscape detail in real-world tests due to noise and processing quality.

Neither camera offers weather sealing, so outdoor shooting in inclement weather requires caution.

Zoom capabilities are modest; Casio provides a tangible telephoto reach (3x zoom), good for framing landscapes or isolating details without heavy cropping. Samsung’s unknown zoom range may limit versatility here.

Dynamic range is limited on both CCD sensors, making it tricky to capture scenes with intense contrast (bright skies and shaded foregrounds). Shooting in RAW would help, but neither provides this.

You’ll want to shoot on low ISO with tripod support (not included) to maximize image quality.

Wildlife and Sports: Do These Cameras Keep Up with Fast Action?

Frankly, ultracompacts like these aren’t first choices for jumpy wildlife or sports action. Why? Autofocus speed, burst rate, and lens reach are all suboptimal.

Neither Casio nor Samsung supports continuous autofocus, face tracking, or fast burst shooting, making it difficult to track animals or athletes on the move.

The Casio lens’s telephoto reach (approx. 107 mm equivalent) covers some bird photography in a pinch, but manual focus helps here. Samsung’s undocumented zoom range leaves me skeptical for anything beyond casual snaps.

Shutter lag and slow focus hunting at lower light compound difficulties.

If shooting fast action is your main goal, look elsewhere - these are better suited for still, controlled subjects.

Street and Travel Photography: Portability Meets Versatility

This is perhaps where ultracompacts thrive and justify their existence.

Both cameras boast excellent portability (see size comparison), so they can slip into a jacket pocket for spontaneous street photography or travel.

Samsung’s slimmer silhouette and larger LCD screen make framing street scenes easier, while Casio’s more comfortable ergonomics reduce fatigue on longer urban strolls.

Battery life details are scarce on both, but the Casio uses an NP-82 battery, removable and replaceable; Samsung does not specify battery type, which might indicate proprietary capacity limitations.

No wireless connectivity on either (no Wi-Fi, Bluetooth), so immediate sharing demands removing cards and transferring to other devices manually.

Flash ranges are limited, and neither offers external flash support, so low-light street shooting can challenge you, especially given lack of stabilization features (no OIS or sensor-shift).

Macro Photography: Getting Up Close and Personal

Among ultracompacts, macro capabilities vary widely.

Casio EX-Z35 offers a macro focus range down to 10cm, which gets you fairly close to small subjects, flowers, and textures. Samsung lacks this specification, suggesting either no dedicated macro mode or less effective close focusing.

No stabilization technology on either makes handheld macro shots challenging - tripods or steady surfaces are highly recommended.

Manual focus on Casio aids precision here; Samsung’s full autofocus reliance can struggle to lock at very close distances.

Night and Astro Photography: Can These Pocket Titans Shine in the Dark?

Shooting stars and night scenes require strong high-ISO performance, long exposures, and ideally manual controls.

Both cameras top out at ISO 3200, but noise levels become obtrusive beyond ISO 400 on both models.

Casio’s minimum shutter speed goes to 4 seconds, potentially useful for night sky shots, whereas Samsung extends longer to 8 seconds, offering more flexibility for long exposure. However, both lack built-in stabilization, so a tripod is essential.

No bulb mode, RAW capture, or manual exposure adjustments are significant shortcomings for astrophotographers.

In practical terms, casual night shots are possible but will be noisy and soft compared to dedicated low-light cameras.

Video Capabilities: From Home Movies to Travel Vlogs

Looking at video specs sheds light on multimedia potential.

The Casio EX-Z35 records at a modest maximum resolution of 848 x 480 (WVGA) at 30fps in Motion JPEG format. That’s standard definition - this camera was never geared towards serious video work.

Samsung ST93 steps up with HD video capture at 1280 x 720 (720p) at 30fps, no specified codec (likely MPEG-4 or Motion JPEG), which is a notable improvement over Casio for casual video.

Neither has touchscreen interfaces or microphone ports, limiting control over sound quality.

No video stabilization on either - handling jitter is up to your grip or external rigs.

If video quality is a priority, Samsung wins slightly, but both are only entry-level options.

Build Quality and Reliability: Durability for Everyday Use?

In terms of construction, neither camera is weather sealed or shockproof. Both suit casual, dry-day shooting but shouldn’t be exposed to heavy moisture or rough handling.

Casio includes a built-in flash with an advertised range of 3.2 m, helpful for fill-in light. Samsung’s flash range details are missing.

Buttons and dials on Casio feel more robust under repeated use; Samsung’s minimalist controls may feel cheaper over time.

Lens Ecosystem and Expansion: Fixed Commitment

Fixed lenses, characteristic of ultracompacts, mean no option for changing optics - what you see is what you get.

Casio’s focal length range is fairly versatile (36-107 mm equivalent), while Samsung’s remains unspecified, making detailed evaluation impossible.

No support for external flashes or accessories limits creative expansion.

Connectivity, Battery, and Storage: Basics Covered, No Frills

Both cameras lack Wi-Fi, Bluetooth, NFC, or GPS - no instant wireless interaction.

Storage is via SD/SDHC cards on Casio; Samsung’s info is less clear, suggesting standard memory card support.

Casio’s use of the NP-82 battery means you can stock spares for extended shoots; Samsung lacks detailed battery specs, hinting at less available aftermarket support.

USB connectivity is minimal: Casio offers USB 2.0 but Samsung surprisingly lists no USB port, implying reliance on card readers for file transfer.

Real-World Image Examples and Performance Scores

Put simply, these cameras deliver decent image quality in bright, well-lit conditions with stationary subjects. Expect noise and limited detail in dim environments.
