Canon PowerShot A3400 IS vs Olympus SZ-31MR iHS: A Hands-On Comparison of Compact Superzoom Cameras

When it comes to affordable compact cameras designed for everyday use, Canon and Olympus have long been solid players, each offering solutions that appeal to casual shooters and photography enthusiasts alike. In this detailed comparison, I put two 2012-era superzoom compacts - the Canon PowerShot A3400 IS and the Olympus SZ-31MR iHS - head-to-head. Both cater to photographers looking for convenience and reach in a pocketable package, but they target subtly different priorities.

Drawing from my extensive experience testing small sensor cameras, plus side-by-side evaluations under varied lighting and shooting scenarios, I delve beyond the specs to reveal how each camera performs across real-world photography disciplines - from portraits to landscapes, wildlife to macro, and even casual video capture. Throughout, I’ll share insights about their underlying sensor technologies, autofocus systems, ergonomics, lens capabilities, and more.

Whether you’re a beginner seeking a no-fuss snapshot machine or a hobbyist craving image versatility on a strict budget, read on to understand which of these compact superzooms deserves a spot in your gear bag.

Size, Build, and Ergonomics: Compactness Versus Control

Let’s start by sizing up the twins in body design and handling. Here’s a clear look at their physical proportions:

The Canon A3400 IS is exceptionally slim and lightweight, tipping the scales at just 126 grams and measuring roughly 94 x 56 x 21 mm. Its narrow profile feels pocket-friendly and virtually disappears in your hand or bag. The ergonomics are deliberately minimalist, reflecting its budget compact status: controls are sparse, with no manual dials or dedicated exposure modes. It’s designed for point-and-shoot simplicity - no muss, no fuss.

In contrast, the Olympus SZ-31MR iHS is noticeably chunkier and heavier at 226 grams and 106 x 69 x 40 mm. That extra heft and volume owe to its more advanced lens mechanics, stabilization system, and a robust build with textured grips that facilitate steadier handling. Though not overtly rugged or weather-sealed, the SZ-31MR’s feel inspires a bit more confidence for extended shooting bouts. The control layout is more generous, albeit still limited to basic compact camera functions without manual exposure options.

Taking the user interface further, the top control decks reveal key operational differences:

Olympus opts for a mode dial with several scene presets, auto modes, and a dedicated playback button - streamlining mode switching without fumbling through menus. The Canon keeps it very barebones with fewer buttons, relying mostly on a mode menu. For photographers who seek quick adjustment and more tactile control, the SZ-31MR’s design is preferable. The Canon’s approach favors absolute beginners or travelers prioritizing size and simplicity.

Sensor and Image Quality: Small Sensors, Big Differences?

Both cameras feature a 1/2.3-inch sensor size, a common standard among compacts, but their sensor types and processing chips shape image output considerably.

The Canon A3400 IS uses a CCD sensor with 16-megapixel resolution, max ISO 1600, and a fixed anti-aliasing filter. CCD technology generally delivers good color but struggles somewhat with noise at higher ISOs and lacks the readout speed advantage of CMOS sensors.

By contrast, the Olympus SZ-31MR iHS employs a 16-megapixel backside-illuminated CMOS sensor, paired with its Dual TruePic V image processor. This combination enhances light gathering efficiency, reduces noise at elevated ISO values (up to ISO 6400), and supports faster data throughput. The SZ-31MR’s BSI-CMOS sensor, along with the absence of the anti-aliasing filter, typically yields sharper, cleaner images - a noticeable edge in low-light and high-dynamic-range situations.

My tests confirm that while both cameras produce decent quality JPEGs under bright conditions, Olympus retains better detail and cleaner shadows when light wanes. In particular, skin tones exhibit more natural gradation on the SZ-31MR, partly thanks to the more capable processor and sensor technology.

LCD and Interface: Navigating Your Shots with Confidence

The rear-screen experience is crucial on compacts that lack viewfinders - both cameras omit electronic or optical viewfinders, relying exclusively on LCDs.

Here, the Olympus SZ-31MR iHS shines. Its 3-inch HyperCrystal III TFT screen boasts an impressively high resolution of 920k dots, resulting in crisp, bright image previews that make manual framing and focus checks much easier. Touch sensitivity works well, improving menu navigation and focus point selection.

The Canon A3400 IS features a similar-sized fixed 3-inch touchscreen but at a modest 230k-dot resolution, noticeably dimmer and blurrier under bright daylight. While touch operation is functional, the lackluster screen severely hampers composition accuracy in the field.

For anyone prioritizing easy framing, especially in varied lighting, the Olympus is the obvious choice.

Lens and Zoom Capability: The Reach Versus Speed Tradeoff

Next, lens specs frequently dictate how versatile a compact can really be - especially if you want that all-in-one camera for travel or wildlife.

Canon’s A3400 IS sports a 28–140 mm equivalent zoom lens with a bright-ish aperture range of f/2.8–6.9. With a 5x optical zoom, it’s somewhat limited for telephoto use but benefits from a relatively fast wide end, useful for indoor or lower light shots.

The Olympus SZ-31MR iHS features a much more ambitious 25–600 mm equivalent superzoom (24x optical zoom), spanning ultra-wide to super-telephoto focal lengths. Aperture ranges from f/3.0 at wide to f/6.9 at maximum zoom. This expansive reach enables capturing distant subjects - wildlife, sports action, or architectural details - without swapping lenses, a significant flexibility advantage.

However, the Olympus lens is slower at the wide end and narrow aperture at telephoto, which can challenge low-light usability without a tripod. The Canon’s optical image stabilization (hybrid optical) versus Olympus’s sensor-shift stabilization both assist handholding but the latter proved more effective during my tests at longer focal lengths.

Autofocus, Continuous Shooting, and Performance: Who Catches the Moment?

Autofocus (AF) is a make-or-break feature for many - especially for wildlife, sports, and street photographers who require speed and accuracy.

• The Canon A3400 IS relies on contrast-detection AF with 9 focus points, face detection, and center-weighted metering but no live view AF support. It offers three AF modes - single, continuous, and tracking - with modest accuracy. Its single-shot continuous rate is a sluggish 1 fps, limiting burst shooting.

• The Olympus SZ-31MR iHS incorporates contrast-detection AF as well, enhanced by its Dual TruePic processor, with continuous tracking and face detection. Burst shooting rates max out at 7 fps, a standout for compacts in this class.

In my time shooting fast-moving scenarios - such as running children or urban street scenes - the Olympus consistently nailed focus faster and retained lock better than the Canon, which occasionally hunted or focused too slowly. Its higher burst rate also means less chance of missing the perfect decisive moment.

Real-World Performance Across Photography Genres

How do these cameras perform across varied photographic applications? Below, I break down strength areas for each in commonly pursued genres and user scenarios.

Portrait Photography

Portraits demand natural skin tones, reliable face/eye detection, and pleasing background blur (bokeh).

• Canon A3400 IS: Skin tones render warm and pleasing under indoor flash and daylight - typical for Canon’s color science. However, its small sensor and slow zoom lens struggle to create meaningful background separation; bokeh is quite limited due to the lack of aperture control.

• Olympus SZ-31MR iHS: Delivers similarly good skin tones with slightly better clarity and contrast. Face detection proved more reliable in mixed lighting. While bokeh remains minimal due to sensor and aperture limitations, slightly longer focal lengths help isolate subjects better.

Landscape Photography

Shooters demand wide-angle field of view, expansive dynamic range, and enough resolution for large prints.

• The Olympus’s 25mm ultra-wide end trumps the Canon’s 28mm, providing improved framing options in tight environments and scenic vistas. Both cameras offer 16MP resolution, but Olympus’s BSI sensor yields better dynamic range and shadow retrieval.

• Neither sports weather sealing, limiting outdoor endurance; however, Olympus’s robust feel gives marginally better handling during extended use.

Wildlife Photography

Wildlife shooters prize fast autofocus, long telephoto zoom, and rapid burst capture.

• Olympus SZ-31MR iHS shines here with 600mm reach and 7 fps burst. I successfully captured distant birds and fleeting animal behaviors with less shutter lag and better focus tracking.

• The Canon A3400 IS cannot compete on zoom length or AF speed, making it suitable only for very casual animal shots at close range.

Sports Photography

Capturing rapid action requires precise AF tracking, low shutter lag, and high frame rates.

• Olympus again leads with 7 fps continuous modes and better AF tracking. In low-light gym or dusk games, the higher max ISO of 6400 (though noisy at top end) provides some buffer.

• Canon’s sluggish 1 fps makes it ill-suited for most sports beyond slow moving or posed subjects.

Street Photography

Discreetness, responsiveness, and portability are essential here.

• Canon’s compact size and light weight make it easy to carry and inconspicuous.

• Olympus’s larger body and longer lens can attract attention and feel bulkier on quick city walks, though its speed offers more shooting opportunities.

Macro Photography

Close focusing precision and magnification matter most.

• Olympus edges out with a 1 cm macro focusing distance (vs. Canon’s 3 cm) allowing tighter close-ups - handy for flowers, textures, and detail shots.

• Both offer image stabilization which helps at close distances where camera shake magnifies.

Night and Astrophotography

High ISO sensitivity and long exposure control dominate here.

• Olympus’s ISO 6400 capability and sensor-shift stabilization enable better handheld low-light shooting. Its minimum shutter speed comes down to 4 seconds (vs Canon’s 15 seconds), facilitating slightly longer night exposures.

• Canon’s ISO tops at 1600, and the slower sensor limits noise control - less ideal for challenging low-light or star shots.

Video Capabilities

Flexibility in video recording attributes adds to everyday utility.

• Olympus SZ-31MR iHS records Full HD 1080p at 30 fps, offering noticeably sharper and better stabilized footage. HDMI output also supports external monitoring.

• Canon A3400 IS captures only 720p HD at 25 fps with basic stabilization, lacking HDMI and external audio support. Video quality is adequate but unremarkable.

Travel Photography

An all-in-one camera for vacation and adventure shoots needs versatility, battery life, and size/weight balance.

• Canon’s minimal weight and slim dimensions excel for travel packing. Battery life runs to 180 shots - average but manageable.

• Olympus carries a battery rated for 200 shots and offers significant zoom versatility, an advantage for varied travel scenes. The price difference and slightly larger form factor might deter some.

Professional Work and Workflow

Neither camera targets professional use due to absence of RAW support or advanced controls.

• However, Olympus’s better image quality, enhanced video specs, and wireless Eye-Fi compatibility offer more flexible integration for casual professional applications or social media content creation.

• Canon’s strict JPEG-only constraint and limited controls restrict its utility in pro workflows.

Technical Deep-Dive: Autofocus, Stabilization, and Connectivity

Several nuanced systems differentiate these compacts in practical use.

Autofocus System

Both use contrast-detection AF without phase detection pixels. Yet, the Olympus benefits from a dual-processing engine enabling continuous AF tracking during video and burst shooting - a rarity among 2012 compacts.

Meanwhile, the Canon relies on a more conventional AF system with slower focus acquisition and no live view AF enhancement.

Image Stabilization

Canon’s optical stabilization works by shifting lens elements, moderately effective across most focal lengths but less so at extreme telephoto or macro distances.

Olympus implements sensor-shift stabilization, physically moving the sensor to compensate camera shake. This approach is generally more effective, especially evident at long zoom and close focus distances, leading to crisper images overall.

Connectivity Options

Olympus’s Eye-Fi wireless card compatibility enables some degree of wireless image transfer - a valuable feature for quick sharing, although it lacks integrated Wi-Fi or Bluetooth.

Canon offers no wireless connectivity options, relying solely on USB 2.0 data transfer.

Pricing and Value Assessment

The Canon A3400 IS was priced around $230 at launch and remains available on secondary markets as a budget compact. It offers straightforward photography for beginners or minimalists at a very low cost.

The Olympus SZ-31MR iHS often commands a slightly higher price point (though varies due to production status). Given its richer feature set, superior image quality, and performance benefits, it represents better value for those willing to invest a bit more.

Summary of Performance Ratings Across Genres

To visually illustrate how these two cameras rank in common photographic categories, here is a comparative chart based on extensive side-by-side testing:

The Olympus clearly outperforms the Canon in wildlife, sports, macro, video, and low-light segments, while the Canon holds its ground in street and portrait due to compactness and decent skin tone rendering.
