Canon PowerShot A3100 IS vs Samsung MV800: A Hands-On Comparison of Two Small Sensor Compacts

In the realm of small sensor compact cameras - often the entry point for casual shooters or photographers seeking a highly portable second camera - choices abound, but real-world performance and user experience can vary significantly despite similar spec sheets. Today, I’m digging deep into two such cameras that, on paper, promise accessible photography with modest feature sets: the Canon PowerShot A3100 IS and the Samsung MV800.

Both released in the early 2010s, these models represent a slice of the small sensor compact market before smartphones took over. While neither is cutting-edge by today’s standards, understanding their strengths, weaknesses, and practical usability remains valuable - not just as a historical exercise, but for anyone hunting bargain-basement compacts or assessing legacy equipment.

I’ve spent hours testing these cameras side-by-side, examining their build, image quality, autofocus behavior, and feature usability across multiple photography styles. Let’s unpack their attributes, armed with both technical knowledge and real-world experience, to help you decide which, if either, deserves a spot in your kit.

Size, Ergonomics, and Handling: What Do Your Hands Prefer?

First impressions count. The Canon A3100 IS measures 97 x 58 x 28 mm and weighs in at 165g, while the Samsung MV800 is notably more svelte at 92 x 56 x 10 mm and just 121g. The Canon’s thicker profile and chunkier feel offer a more substantial grip - which I found helps with one-handed shooting stability, especially for longer sessions or when zoomed in.

The Samsung’s slim, almost wafer-like design prioritizes portability above all else. Its thin body slips effortlessly into small pockets or purses - a key consideration if you rely on stealth or convenience, such as street or travel photography.

Ergonomically, the A3100’s physical buttons are more tactile and distinct, aiding quick adjustments without fumbling. The MV800’s streamlined facade channels a minimalist vibe, but the reduced physical differentiation sometimes made it tricky to handle confidently, particularly in gloves or low light.

In summary: if you prioritize comfort and traditional handling, the Canon edges ahead, while the Samsung embodies ultra-portability.

Control Layout and Interface: Accessibility in the Moment

Having worked extensively with compact cameras, I appreciate how control placement influences shooting flow. The A3100 IS features classic top and rear button placement with a dedicated zoom rocker, a mode dial buried in menus, and no touchscreen. For me, that meant a steeper learning curve with menu navigation but no worries about accidental screen taps.

Conversely, the Samsung MV800 integrates a sophisticated 3-inch tilting touchscreen (460k dots), a noteworthy leap forward for its time. This touch interface simplifies focus point selection and menu adjustments dramatically. The flip-out nature of the screen also helps compose unconventional angles, benefiting enthusiasts who favor creative framing or self-portraits (even though neither camera advertises specific selfie modes).

The two interfaces reveal a philosophical split: Canon adheres to tried-and-true button interactions, ideal for users who prioritize tactile feedback; Samsung leans into touchscreen tech to reduce physical controls, fostering a more modern yet sometimes fiddly interaction.

Sensor Technology and Image Quality: The Real Heart of the Camera

Both the Canon A3100 IS and Samsung MV800 employ a 1/2.3-inch CCD sensor, measuring about 6.17 x 4.55 mm with an imaging area of roughly 28 mm². This class of sensor commonly balances cost and size with respectable output for casual shooting - notably behind the curve compared to larger APS-C or full-frame sensors, which dominate prosumer and professional landscapes.

The Canon captures images at 12 megapixels, while the Samsung ups the ante slightly with 16 megapixels. However, as a veteran camera tester, I’ve observed that higher resolution on a small sensor invites more noise and reduced low-light sensitivity - especially with older CCD technology.

In my controlled lab tests and real-world shooting, the Samsung images exhibit marginally finer detail under bright conditions - thanks to the higher pixel count and tighter JPEG processing. Yet, Canon’s output tends to render smoother tones with less aggressive edge sharpening, favoring a natural look.

Dynamic range in both cameras is narrow, as expected for CCD small sensors: highlights clip quickly, and shadows hold limited detail. Color reproduction is mostly accurate but slightly warmer in the Canon, and cooler (leaning blue) in the Samsung. Both utilize an anti-aliasing filter to suppress moiré patterns, trading off some ultimate sharpness.

If low light or high ISO shooting tops your priorities, neither excels - noise becomes problematic above ISO 400 on Canon and ISO 800 on Samsung, though the Samsung’s sensor can stretch dark scenes a little further.

LCD Screens: Your Window to the World

User interface comfort extends beyond controls to how you visualize your shot. The Canon’s 2.7-inch fixed LCD offers only 230k dots resolution. While serviceable, this screen feels slightly grainy, and outdoor visibility under sunlight is limited.

The Samsung’s 3-inch 460k dot tilting touchscreen raises the bar considerably, with crisp detail and flexible viewing angles. This certainly enhances the shooting experience, particularly when connecting autofocus via touch or composing shots from challenging perspectives.

Neither camera offers any viewfinder option - not even electronic - so reliance on the LCD is total. The Samsung’s better screen technology lends it a measurable advantage for composing and reviewing images in various lighting conditions.

Autofocus Systems: Speed and Accuracy in Practice

Both models utilize contrast-detection autofocus systems with no phase-detection elements, common in devices targeting the compact market during their release periods.

The Canon A3100 IS operates with a 9-point AF system but lacks face detection or continuous tracking capabilities. In practice, focus acquisition is slow (often upwards of a second), and hunting under low contrast scenarios is frequent.

The Samsung MV800, however, offers a more advanced AF package with face detection, center-weighted focus, multi-area AF, and touch-to-focus via its screen - features that enable faster and more reliable focusing on human subjects, particularly in well-lit environments.

For wildlife or sports photography, neither camera is suitable due to sluggish single-shot autofocus and limited continuous shooting rates - the Canon clicks off only at 1 FPS, and Samsung’s burst rate is unspecified but effectively minimal.

Zoom Ranges and Lens Characteristics: Flexibility and Optical Quality

Fixed lens ranges for both cameras cover practical zoom territory:

• Canon A3100 IS: 35-140 mm (35mm equivalent) - a modest 4x optical zoom, with a moderate maximum aperture of f/2.7 at wide angle, tapering to f/5.6 telephoto.

• Samsung MV800: 26-130 mm (5x optical zoom) - slightly broader wide-angle coverage useful for landscapes or groups, starting at f/3.3, tightening to f/5.9 at full zoom.

The Canon’s brighter wide end aperture lends it an edge in low light and shallow depth-of-field potential - though both cameras inherently struggle to generate bokeh due to sensor size limitations.

Image stabilization is optical on both models, effectively combating handshake at extended zoom lengths and slower shutter speeds. This feature is vital since neither provides manual shutter speed or aperture control that would otherwise allow more creative exposure settings.

Photography Disciplines: Real-World Workflows Examined

Given the specifications and practical testing, let me breakdown how each camera fares in key photography genres and use cases:

Portrait Photography

Portraiture demands accurate skin tones, reliable autofocus on faces, and pleasing background separation (bokeh).

The Samsung MV800’s face detection AF and touch focus help lock onto eyes reliably during portrait sessions, and its slightly higher resolution supports decent facial detail. However, shallow depth-of-field rendering is minimal from either camera, due to sensor size and optics.

The Canon A3100 IS delivers warm color reproduction that flatters skin tones, but its slower and less sophisticated AF impedes quick capture of fleeting expressions.

Bottom line: Samsung offers a more intuitive toolset for portraits, but don’t expect creamy bokeh or professional-grade skin tone accuracy from either.

Landscape Photography

Here, resolution, dynamic range, and lens coverage take prominence.

The Samsung again wins with its higher 16 MP resolution and wider 26 mm wide-angle, providing more scene context and cropping latitude. The tilting screen aids handheld compositions at steep or low angles.

The Canon’s weaker zoom range and smaller screen are limitations, but its slightly superior color depth and smoother tonal gradations benefit landscape images shot in consistent light.

Neither camera is weather sealed; neither suited for harsh or wet conditions. Both are compact and light, with storage expandable via SD or Micro SD cards respectively.

Wildlife and Sports Photography

Neither camera is a likely top contender here. Both have modest continuous shooting and sluggish AF, making tracking fast-moving subjects frustrating or unworkable.

Canon’s 1 FPS burst rate and fixed AF lead to missed critical moments, while Samsung’s continuous shooting details are missing, but its face-detection won't help with animals or erratic movement.

Optical zoom ranges on both are somewhat restrictive for distant subjects.

For serious wildlife or sports shooting, you’d want to upgrade to interchangeable-lens systems or at least bridge cameras with faster AF.

Street Photography

Street shooting rewards stealth, discretion, and responsiveness.

Samsung’s smaller, slimmer MV800 - with its silent touchscreen AF and flip screen for candid angles - feels optimized for unobtrusive shooting. Turning on touch focus lets you frame and lock exposure cleverly without repositioning.

The Canon’s bulkier presence and slower AF can make it less agile for spontaneous moments.

Both cameras lack viewfinders, relying on LCD compositions, and neither excels in low light, but the Samsung screen’s higher brightness and touch interface create a more pleasant experience on bustling city streets.

Macro Photography

The Canon’s close focusing ability to 3 cm grants it an edge for macro enthusiasts capturing close-up details.

Samsung does not specify a macro focus range; therefore, it likely isn’t as adept at close up work.

Both cameras have optical image stabilization to steady macro shots, but limited manual focus or focus bracketing means you must rely solely on AF precision, which is often inadequate for demanding macro work.

Night and Astro Photography

Despite their CCD sensors, noise control and long exposures users associate with night/astro photography present challenges for these cameras.

The Canon offers a minimum shutter speed of 15 seconds, enabling long exposures needed for astrophotography or creative night scenes. The Samsung’s longest shutter is about 8 seconds, which limits versatility here.

High ISO performance is poor on both - noise becomes an issue above ISO 400 (Canon) or ISO 800 (Samsung), so quality suffers in dim conditions.

Neither camera supports RAW output for extended post-processing flexibility; JPEGs are the only option, limiting dynamic range recovery.

Video Capabilities

The A3100’s video maxes out at 640x480 (VGA) at 30 fps, using Motion JPEG format - a relatively low resolution by today’s standards, producing bloated files with limited editing latitude.

In contrast, the Samsung MV800 records 1280x720 HD at 30 fps with MPEG-4 and H.264 codecs, improving compression efficiency and image fidelity.

Neither camera offers external microphone inputs or headphone jacks, and neither sports in-body video stabilization beyond basic optical.

If video is a consideration, Samsung provides a noticeably more usable package.

Travel Photography

When packing light, travelers prize versatility and battery endurance.

Samsung’s lighter body and superior zoom range deliver on portability and framing options. The tilting touchscreen aids composition on-the-go.

Canon’s weight and bulk aren’t excessive but might be cumbersome for all-day carry.

Battery life data isn’t specified for either - but generally, compact cameras of this era handle between 200–300 shots per charge, which is modest.

Build Quality and Reliability

Neither camera includes weather sealing or ruggedization features such as dustproofing or freeze resistance - reasonable omissions at these price points.

The Canon’s thicker body gives a more robust feel. The Samsung, while sleek, feels more delicate due to its slim chassis and flip screen.

Both use proprietary rechargeable battery packs (Canon NB-8L vs Samsung BP70), limiting aftermarket options but typically providing adequate power under normal usage.

Storage and Connectivity

The Canon uses standard SD/SDHC cards, while the Samsung opts for Micro SD - important for users who may want to reuse existing cards or integrate with other devices.

Neither camera offers wireless connectivity options such as Wi-Fi, Bluetooth, or NFC - typical for their production era but a disadvantage today.

USB 2.0 ports provide simple file transfers; only Samsung includes an HDMI output for playback on external screens.

Price-to-Performance: Value Judgments

The Canon A3100 IS currently can be found in the neighborhood of $159, targeting budget-conscious users prioritizing ease of use and moderate image quality.

The Samsung MV800 commands a higher price, approximately $499, reflecting its advanced features such as the tilting touchscreen, higher resolution sensor, and HD video recording.

While the Samsung’s specs are objectively superior in many respects, the cost difference demands consideration: is the significantly better screen, additional zoom range, and video capability worth paying over three times more?
