Canon A3400 IS vs Olympus TG-820 iHS

Canon A3400 IS vs Olympus TG-820 iHS: A Hands-On Comparison for the Budget-Conscious Enthusiast

As someone who has spent over fifteen years testing and comparing cameras, ranging from pro-level bodies to everyday compacts, the experience is a bit like sifting through clubs for thumbs: the right tool makes all the difference. Today, I’m diving into two entry-level compact cameras announced back in early 2012 - the Canon PowerShot A3400 IS and the Olympus TG-820 iHS. Both offer modest specs but target very different users with distinct priorities.

In this in-depth comparison, I’ll explore real-world performance, technical details, and practical usability to help you decide which of these small-sensor compacts might fit your photography style and budget. Whether you’re a hobbyist wanting something simple or a traveler needing rugged reliability, you’ll find plenty to chew on here.

First Impressions Matter: Design, Size, and Handling

From the outset, form factor plays a surprisingly large role in comfort and shooting confidence, especially for compact cameras stripped of pro grips.

The Canon A3400 IS is a diminutive little camera - measuring just 94x56x21 mm and weighing a featherlight 126 grams. It feels truly pocketable, slipping easily into smaller bags or large jacket pockets. Ergonomically, it’s a basic design without pronounced thumb rests or textured grips. The control layout is straightforward, ideal for anyone who does not want to wrestle with menus mid-shot.

In contrast, the Olympus TG-820 iHS hefts in at 206 grams and is chunkier at 101x65x26 mm. This bump in size and weight reflects its rugged construction - more on that later. The TG-820 feels solid in hand, with rubberized sections that greatly improve grip when you’re wearing gloves or your hands are wet. For users who plan to shoot outdoors or underwater, that durability and extra heft are genuine positives.

Let’s take a quick peek at the top control layouts:

Both cameras keep things minimal, lacking complex dials or clubs-for-thumbs rear joysticks. Canon’s minimalist approach suits beginners, with few buttons to memorize. Olympus adds a dedicated “Mode” dial with easy access to underwater or scene modes, hinting at its adventure-ready mindset.

Ergonomics Winner: If portability and pocketability top your list, Canon’s A3400 IS edges ahead. But for rugged grip and outdoor-ready handling, Olympus TG-820 iHS is clearly built for tougher conditions.

Sensors and Image Quality: What Lies Beneath the Lens

Now, let's get technical. Both cameras use the familiar 1/2.3" sensor size, measuring 6.17 x 4.55 mm - tiny by DSLR or mirrorless standards but typical for compacts.

The Canon A3400 packs a 16-megapixel CCD sensor. CCDs were the standard back then, offering decent color reproduction but generally lagging behind CMOS sensors in noise performance and high ISO capabilities. The maximum ISO topping out at 1600 restricts low-light usability.

Olympus employs a 12-megapixel CMOS sensor paired with their TruePic VI image processor. While lower in resolution, CMOS sensors typically offer better noise handling and can deliver cleaner images in challenging lighting. The TG-820’s maximum ISO of 6400 suggests more flexibility shooting indoors or at night.

From my testing methodology, which includes controlled lab environments and real-world scenarios, sensor technology combined with image processing impacts final images far beyond megapixels alone. The Olympus’ sensor and processor pairing give it an edge for low-light and outdoor dynamic range.

Put simply: The Canon’s 16MP sensor yields sharper daylight shots - great for landscapes and detailed snaps - but its noise degradation after ISO 400 limits use in dimmer conditions. The Olympus 12MP sensor won’t win on resolution but produces noticeably cleaner results at higher ISOs.

The Viewfinder and Screen Battle: How You Frame and Review Shots

While neither camera includes an optical or electronic viewfinder - a staple in compacts at this price point - their rear LCD screens make framing and playback their bread and butter.

Here, the Olympus TG-820 steals the show hands down. It sports a 3-inch HyperCrystal III TFT LCD, boasting a sharp 1030k-dot resolution that stays visible in bright sunlight. As someone who has lost count of how many times a dim screen dashed my plans outdoors, this is a major advantage.

Canon’s A3400 IS uses a similar 3-inch screen but with only 230k dots. The lower resolution screen tends to look pixelated up close, and reflections under daylight can hamper composing and reviewing images. Both cameras offer fixed displays, but I appreciated Olympus’ superior screen technology for both usability and confidence in framing.

Bonus usability note: The Canon incorporates a touchscreen interface (rare in its class back then), which occasionally speeds navigation, though its sluggish responsiveness sometimes made me long for physical buttons. The Olympus sticks to traditional buttons but balances this with faster menu responsiveness.

Autofocus, Speed, and Burst Shooting: Capturing the Moment

One area that separates casual snapshot compacts from anything approaching enthusiast usability is autofocus (AF) performance and responsiveness.

The Canon A3400 has a 9-point contrast-detection AF system with face detection. However, it only manages a rather poky continuous shooting speed of 1 frame per second (fps). In practical terms, that makes it a no-go for fast action or wildlife where split seconds count.

Olympus takes a different route with its contrast-detection AF coupled with face detection and 5 fps continuous mode. While 5 fps is quite modest compared to DSLRs or mirrorless beasts, it’s a stark improvement here and gives the TG-820 a clearer advantage in queuing up quick snapshots or smaller bursts to catch fleeting moments.

Besides burst, the Olympus’s AF precision was visibly faster locking focus in my indoor and outdoor tests, especially under lower light, presumably helped by its more modern sensor and processing. Canon’s autofocus hunted more noticeably when tracking moving subjects.

Lens Quality and Zoom Versatility

Both cameras share the same 28-140 mm (35mm equivalent) 5x zoom range, framing the standard travel and general photography sweet spot.

Canon touts a maximum aperture range of f/2.8-6.9: brighter at the wide end but dropping into the dimmer realm at full zoom, which can limit low light performance at telephoto. Olympus has a slower f/3.9-5.9 lens but combines it with sensor-shift image stabilization (IS), versus Canon’s optical IS.

In hands-on usage, both lenses are decent generalists, but the Canon does a better job wide open due to the brighter aperture. Still, Olympus’s stabilization helps offset camera shake across that entire zoom range, which is critical when shooting in low light or without a tripod.

Neither camera offers interchangeable lenses or manual aperture control, reflecting their clear budget, beginner-focused positioning - a constraint to keep in mind if you dream of expanding your optical toolkit.

Durability and Weather Resistance: The Olympus Advantage

Here’s where these two really diverge.

The Canon A3400 IS is a basic, non-weather-sealed compact. It offers no rugged features and demands guarded handling around dust, water, or shocks. It’s designed for dry, casual use - like family snapshooter interested in simplicity.

By contrast, Olympus’s TG-820 iHS is the classic durable “tough” camera: waterproof, dustproof, shockproof, crushproof, and freezeproof. Its construction is sturdy enough to survive submersion up to 10m and drops from 2m, making it ideal for hiking, snorkeling, or adventures where your camera could get roughed up a bit.

If you spend a lot of time outdoors or want a “grab and go” camera that can survive more than an accidental rain shower, Olympus’s rugged design is a major, possibly decisive selling point.

Battery Life, Storage, and Connectivity

Battery life on both is modest, but the Olympus TG-820 manages around 220 shots per charge compared to Canon’s 180. Not huge wins, but every shot counts when on the road without a charger. Both use proprietary rechargeable battery packs with single SD/SDHC/SDXC card slots.

Connectivity-wise, neither boasts Wi-Fi, GPS, NFC, or Bluetooth. USB 2.0 ports handle easy data transfers, and only Olympus adds an HDMI output for clean playback on larger screens - handy if you want to review vacation photos on the big TV.

Image Stabilization and Video Capabilities

Both cameras feature image stabilization, crucial in small sensor compacts to reduce blur from shaky hands:

• Canon uses optical IS built into the lens system.
• Olympus applies sensor-shift IS, which can be more effective since it stabilizes at the sensor level.

From my testing, Olympus’s stabilizer provides slightly steadier shots at telephoto lengths and in low light.

Video-wise, the Canon maxes out at 1280x720p (HD) at 25 fps, more of a casual clip feature than high-quality footage. Olympus steps up with full HD 1920x1080 30 fps recording with H.264 compression - noticeably better for vloggers or anyone wanting decent video quality from their compact.

Neither offers manual video controls or external mic inputs, so serious videographers should look elsewhere, but for casual clips, Olympus’s video hardware is clearly superior.

Sample Image Gallery: Real-World Output from Both Cameras

I’ve included a curated gallery of sample photos taken under varying conditions to give you an honest window into how these cameras perform on the ground.

From daylight landscapes, indoor portraits, to macro flowers, the Canon’s higher megapixel count displays visibly more detail in bright light, while Olympus shines in shadows and low light with cleaner colors and less noise. The difference becomes critical if you shoot portraits or indoor events often, as Olympus maintains softer, more natural skin tones without grain explosions.

Scoring the Cameras: Overall and Genre-Specific Performance

To summarize the strengths and weaknesses, here are the overall and genre-specific scores I attribute based on hands-on experience using standardized testing protocols in labs and real environments.

Looking across the board, Olympus edges ahead with overall usability and image quality combined, but the Canon isn’t far behind as a truly budget-friendly, simple compact.

Breaking it down by photography style:

• Portraits: Olympus wins for skin tone fidelity and low light AF.
• Landscape: Canon’s higher resolution shines, but Olympus’s dynamic range counters well.
• Wildlife & Sports: Neither is a prime choice, but Olympus’s faster AF and burst rate make it marginally better for quick action.
• Street: Canon’s smaller size helps for discreet shooting.
• Macro: Olympus’s 1cm closest focus beats Canon’s 3cm.
• Night/Astro: Olympus runs circles around the Canon, thanks to CMOS sensor and higher ISO.
• Video: Olympus is the undisputed winner here.
• Travel: Olympus’s rugged body and better battery life make it better suited.
• Professional: Neither offers RAW support or manual controls, ruling them out for pros.

Who Should Buy Which? Clear Recommendations

Let me cut through the noise for you:

Buy the Canon A3400 IS if:

• You're a total beginner or casual shooter who wants an ultra-light compact.
• You primarily shoot outdoors in good light and appreciate higher resolution images.
• You value touchscreen controls and very simple operation.
• Budget is tight - you can find this camera at a significantly lower price.

Buy the Olympus TG-820 iHS if:

• You want a rugged, all-weather companion camera that can survive rough conditions.
• You need better low-light and video capabilities.
• You’re an outdoor enthusiast who shoots landscapes, close-up macros, and candid action photos.
• You want a better LCD screen and more confident autofocus.

Real Talk: Where Do Both Cameras Fall Short?

Neither camera supports RAW capture - a huge drawback if you want professional-grade post-processing. Also, manual exposure controls, faster continuous shooting modes, and interchangeable lenses are completely absent, limiting artistic control and growth potential.

Connectivity features are almost non-existent, reflecting their vintage 2012 design and budget status. If wireless image transfer or GPS tagging is non-negotiable, look elsewhere.

Final Thoughts: Value Versus Versatility

These two cameras occupy distinct niche spaces despite similar zoom specs and sensor sizes. The Canon A3400 IS offers straightforward, lightweight simplicity at a more accessible bargain price. In contrast, the Olympus TG-820 iHS delivers robust build quality, better image processing, and features aimed at active photographers.

If you ask me - which thanks for asking! - and you value durability and versatility to shoot beyond sunny days, the TG-820 is a better overall investment despite a heftier price tag. If, however, you want the easiest-to-carry “point and shoot” for family events or daylight use, the A3400 IS remains an appealing, no-frills choice.

In summary, both are honest attempts at accessible photography, but their divergent focuses make Olympus the better travel and adventure companion and Canon the more humble snapshooter’s friend. Your pick should hinge not just on specs, but how, when, and where you plan to shoot.

I hope this hands-on breakdown helps you zero in on the camera that suits your style and budget best.

Happy shooting!
