Samsung ST80 vs Sony TX100V: Two Compact Contenders Under the Microscope

When it comes to ultracompact cameras, compactness and simplicity often mean sacrifice - usually in image quality, controls, or features. But that doesn’t mean these pocket-friendly cameras can’t produce satisfying results for travel, casual shooting, or quick snapshots. Today, I’m stacking up two intriguing offerings that target the ultra-portable niche: the Samsung ST80 (2010) and the Sony Cyber-shot DSC-TX100V (2011). Though close in generation and shared category, these two compact shooters each carry their own distinct personalities and compromises.

Having put both through their paces extensively (and no, neither will replace your full-frame rig), this head-to-head goes beyond spec sheet showdowns, digging into the real-world usability, image quality, and feature sets that photographers - budget-conscious and otherwise - really care about.

Ready to see which one aligns with your photography needs? Let’s break them down.

Pocket Size, Grip, and Design: How They Feel in Your Hands

Ultracompact cameras live and die by how comfortably they sit in your pocket and your grip during shooting. I’m sure you can picture that cringe-worthy moment when a camera slips out due to awkward ergonomics - that’s a deal-breaker for mobile shooters.

Starting with size and weight, both cameras are roughly in the same ballpark:

• Samsung ST80: Measures approximately 92 x 55 x 19 mm and weighs just 118g.
• Sony TX100V: Slightly larger at 97 x 59 x 18 mm, tipping the scales at 147g.

Samsung takes the crown for sheer lightness and a tad smaller footprint, which is brilliant if your aim is to stash a camera with absolutely minimal bulk. The ST80’s rounded edges and slightly thinner profile give it a more pocket-friendly silhouette.

Sony, on the other hand, while still pocket-friendly, feels a bit more substantial and sturdy in hand - more of a “precision tool” than just a carry-it-anywhere toy. Its metal-bodied construction (vs. Samsung’s plastic) also lends it a more premium feel.

Control Layout: Clubs for Your Thumbs or Usable Dials?

Simply pocketable isn’t enough; controls have to be intuitive and fast to access.

Here, both cameras opt for minimalistic top-plate controls to maintain sleekness. The ST80 offers a dedicated mode dial - always welcome for anyone wanting quick access without diving deep into menus. Samsung also throws in shutter priority, aperture priority, and full manual exposure modes, which is pretty ambitious for an ultracompact. Unfortunately, without external rings, adjustments feel menu-dependent, which slows me down in fast shooting scenarios.

The Sony TX100V opts for a more streamlined button-driven control scheme, focusing heavily on automation and user-friendly scene modes but lacks shutter or aperture priority modes. It shoots in full auto or programmed modes. For many casual shooters, this might be a relief - no fiddling, just point and shoot - but enthusiasts might find this limiting.

Overall ergonomics lean slightly in Sony’s favor thanks to a more tactile button response and slightly better-spaced controls. Samsung’s buttons can feel mushy under your finger after prolonged use.

The Heart of the Matter: Sensor and Image Quality

What good is a compact camera without a decent sensor to back it up? Let's dive into their imaging chops.

Sensor Technology and Resolution

• Samsung ST80: Employs a 1/2.3" CCD sensor with 14 megapixels, 6.08 x 4.56 mm dimensions, and a sensor area of roughly 27.7 mm².
• Sony TX100V: Uses a slightly larger and more modern 1/2.3" BSI-CMOS sensor with 16 megapixels, measuring 6.17 x 4.55 mm (28.1 mm² sensor area).

Interestingly, despite being the junior in years, Samsung sticks with the aging CCD tech, whereas Sony incorporates BSI-CMOS - a sensor type with better efficiency and noise characteristics, especially in low light.

In the lab, Sony’s sensor delivers cleaner images at higher ISOs with less color noise and better dynamic range. It also matches higher resolution with 16MP, giving a slight edge in detail capture when shooting at base ISOs.

Samsung’s CCD sensor, while capable of sharp daylight images, struggles in dim settings, showing more grain and less forgiving highlight retention.

Optics: Lenses in the Mix

Lens specs impact real-world image clarity and bokeh:

• Samsung ST80 Lens: 35-105mm equivalent zoom (3x), aperture f/3.3 to f/5.5
• Sony TX100V Lens: 25-100mm equivalent zoom (4x), aperture f/3.5 to f/4.6

Sony’s wider zoom range starts broader at 25mm equivalent, great for landscapes and interiors, while Samsung’s 35mm start is more telephoto-focused.

Samsung’s wider aperture at the long end gets darker (f/5.5), limiting low light and shallow depth of field potential. Sony maintains a more consistent max aperture throughout the zoom range, aiding low light capture and subject isolation.

Evaluating the User Interface: Viewing and Composing Shots

Ultracompacts live or die by their screen usability and finder options (or lack thereof).

Neither camera has a viewfinder, so LCD usability is paramount.

• Samsung ST80 packs a 3-inch 230k pixel touchscreen.
• Sony TX100V sports a larger 3.5-inch 1229k pixel XtraFine OLED touchscreen with TruBlack technology.

Needless to say, Sony’s screen is a joy - bright, detailed, and usable even in harsh daylight. Samsung’s smaller, lower-res screen feels dim and outdated, making precise manual focusing or composition a chore outdoors.

Touch responsiveness on both is acceptable, but Sony’s interface is more fluid and responsive with logical menu grouping. Samsung’s UI feels sluggish - probably a side effect of older processing hardware.

Autofocus System: Speed vs Accuracy in Real Life

Autofocus (AF) can make or break fast shooting opportunities, especially for kids, pets, or street photography.

Both rely on contrast-detection AF systems (a usual trait for compact cameras). However, their implementations differ:

• Samsung ST80 offers single AF with center-weighted and multi-area AF options but no face or eye detection.
• Sony TX100V uses 9 AF points with multi-area, spot, and center-weighted options and adds intelligent AF tracking but lacks face detection.

In practice, Sony’s AF is more reliable and faster to lock, especially in decent lighting. Under low light, both falter, but Sony’s BSI-CMOS sensor and superior processing speed help keep shots usable.

Samsung’s AF feels more “hesitant” and slower, sometimes hunting for focus in challenging contrast conditions, occasionally leading to missed shots.

Burst Shooting and Shutter Speed: For the Momentary and Action Junkies

Burst shooting on ultracompacts is rarely sports-car fast, but some performance matters:

• Samsung ST80: Continuous shooting is not specified, implying very basic or non-existent burst capabilities.
• Sony TX100V: Rated for 10 frames per second burst - highly respectable for a pocket camera.

If your photography leans towards sports, kids, pets - anything with movement - Sony’s TX100V offers a clear edge. It can capture sequences enabling you to pick the sharpest frame, whereas Samsung is limited to single shots that risk missing critical moments.

When it comes to shutter speed ranges:

• Samsung offers 8s (slowest) to 1/1500s (fastest).
• Sony ranges from 2s to 1/1600s.

Samsung’s longer max shutter speed helps with long exposure or night shots, but slower max shutter speed narrowly limits freezing fast action in brighter conditions. Sony's max 1/1600s is adequate, but neither compete with DSLRs for speed.

Flash and Low-Light Performance

Both cameras pack built-in flashes with different ranges:

• Samsung’s flash reaches up to 5 meters, featuring more flash modes including red-eye reduction.
• Sony’s flash range maxes at 4 meters with fewer modes but integrates slow sync for balanced fill.

Low light shooting is generally better on the Sony due to its sensor and image stabilization.

Both cameras have optical image stabilization (OIS), which significantly aids handheld shots in dim environments, but Sony’s newer implementation is more efficient and less likely to produce blur.

Video Capabilities: Enough for Casual Filmmaking?

Looking beyond stills, many of us use compact cameras for impromptu videos.

• Samsung ST80 records HD video at 1280 x 720 at 30 fps (Motion JPEG format).
• Sony TX100V supports Full HD 1920 x 1080 at 60 fps with MPEG-4 and AVCHD formats.

Sony clearly pulls ahead here for video enthusiasts. Higher resolution, smoother frame rates, and professional codec support make the TX100V better for those casual video projects.

Neither camera offers external microphone inputs or headphone jacks, so audio quality sticks to built-in mic performance.

Connectivity and Storage: Modern Needs in an Older Package

• Samsung ST80 supports MicroSD/SDHC with storage internally but no wireless connectivity.
• Sony TX100V provides more flexible storage options, including SD, SDHC, SDXC, Memory Stick Duo, and Pro Duo, plus Eye-Fi wireless card support for easy image transfer. It also boasts a built-in GPS for geotagging - a handy feature for travel and landscape photography.

Sony’s wireless and GPS features add a layer of convenience that Samsung completely misses, making TX100V more attractive for the on-the-go shooter who values instant sharing and location tagging.

Battery Life: Shoot More, Worry Less

Neither manufacturer specifies official CIPA ratings for battery life, but based on extensive usage, Sony’s lithium-ion NP-BN1 fares better than Samsung’s BP70A - yielding more shots per charge (~300 vs. ~200 respectively).

For travel and street photography, battery endurance becomes important; the Sony edges out here.

Price and Value: How Much Bang for Your Buck?

The Samsung ST80 launched at around $249, while the Sony TX100V debuted closer to $380.

The roughly $130 premium for Sony buys you:

• A sharper, larger OLED screen
• Superior sensor technology with higher resolution
• Faster burst shooting
• More video options and better codecs
• GPS and Eye-Fi wireless capabilities

For most enthusiasts, that extra investment translates to a better photographic experience.
