Canon SX510 HS vs Olympus SZ-31MR iHS: The Small Sensor Superzoom Smackdown for Enthusiasts and Pros

Choosing the right camera these days can feel like picking the perfect flock of starlings mid-flight - there’s a dizzying swirl of options, each with its own charm and quirks. Today, I’m diving deep into two compact superzoom cameras from the small sensor camp: the Canon PowerShot SX510 HS and the Olympus SZ-31MR iHS. Both hail from a slightly earlier generation (2012-2013), but their feature sets and unique design philosophies still offer plenty to chew on for those after travel-friendly versatility with enough zoom reach to get creative in the field.

Having thoroughly tested thousands of cameras over 15+ years, I approached these two with a mix of curiosity and mild nostalgia. Spoiler alert: it’s not about the megapixel race here (though Olympus takes a modest lead), but rather about how each handles real-world photography challenges - from portraiture to wildlife, macro to night shots - and which type of photographer they naturally serve best.

Grab your metaphorical popcorn (or camera strap), and let’s zoom into the juicy details with a side-by-side that blends technical insights, hands-on reflections, and a sprinkle of that photographer’s intuition.

So, What Are We Actually Comparing Here?

Both are compact superzoom cameras with 1/2.3” sensors - a tiny format by modern standards but still capable of fun shots if managed well. They target users who want an all-in-one portable solution: decent zoom range, good image stabilization, and video capabilities without dragging a full DSLR kit around. However, how they achieve those goals diverges more than you might expect.

At a glance:

Those raw specs lay the foundation, but it’s the subtle nuances in usability, image quality, and real-life performance where the story unfolds.

Let’s break it down starting with the tactile experience.

Feel, Fit, and Ergonomics: Size and Controls Matter More Than You Think

The first contact you have with a camera often colors your entire experience. Handling comfort, control intuitiveness, and robustness aren’t just trivial details - they impact your shooting confidence.

The Canon SX510 HS tips the scales at 349 grams, noticeably heavier than Olympus’s feather-light 226 grams. Dimensionally, the Canon is chunkier, too. To my hands, it feels more substantial - more “camera” and less “gadget.” For photographers used to DSLRs or mirrorless cameras, this added heft offers familiarity and steadiness. The grip, though minimal, is better contoured on Canon, aiding longer handheld use.

The Olympus SZ-31MR, by contrast, feels pocketable and nimble, leaning clearly into point-and-shoot compact territory - even with that respectable telephoto reach. It’s slimmer front-to-back (only 40 mm thick), making it less conspicuous and easier for street shooters or travelers prioritizing discretion and weight.

Control-wise, Canon opts for traditional dial-driven modes including manual exposure modes - something the Olympus skips entirely. Olympus’s interface is simpler, relying more on automatic modes and touchscreen controls - great for beginners or casual photographers, but it might frustrate those who want more granular exposure control.

The Canon’s button layout is more ergonomic for nuanced shooting - dedicated buttons, a mode dial, and a rear thumb wheel. Olympus streamlines, which helps keep things minimalist but limits quick adjustments and customization.

Both lack electronic viewfinders - a notable omission for outdoor shooting in bright light - and instead rely on LCD screens.

LCD Screens and Interface: Your Window to the World

Canon’s 3” fixed TFT LCD with 461k dots is serviceable, but nothing spectacular. Colors and brightness can wash out under strong sunlight, and no touch functionality limits quick focusing or menu navigation.

Olympus pushes the envelope a bit with a higher-res 920k-dot 3” HyperCrystal III TFT LCD that supports touch input - helpful for focus selection and menu traversal. This makes Olympus feel more “modern” by default, and in many shooting scenarios, I found the touchscreen more intuitive, especially for casual shooters.

One pain point for both: neither articulates. No flips, tilts, or swivels - this is a missed opportunity for handheld low/high angle shooting or selfies, which are popular in this compact class.

Under the Hood: Sensor and Image Quality Realities

Here’s where things get frisky. Both cameras pack the same 1/2.3” sensor size (6.17x4.55mm), meaning physical limitations in pixel pitch and noise control are similar. However, the Olympus’s newer BSI-CMOS sensor is a welcome upgrade over Canon’s older CMOS with DIGIC 4 processor.

Megapixels: Olympus nets 16 MP versus Canon’s 12 MP, giving a slight edge in detail, but not without caveats. Having more megapixels on a small sensor can boost resolving potential but may increase noise and reduce dynamic range if not managed well.

ISO and Noise: Olympus boasts a max native ISO of 6400, compared to Canon’s 3200. However, bumping ISO above 800 on either yields noisy images with smeared detail. I found Olympus’s BSI sensor did slightly better at retaining detail in low-light shots with ISO 800-1600, but the margin isn’t night-and-day.

Dynamic Range: Neither sensor delivers stellar dynamic range, but Olympus’s sensor-shift stabilization indirectly helps capture sharper images at slower shutter speeds in dim conditions, somewhat expanding usable shooting scenarios.

Bottom line: If resolution and shooting in moderately dim conditions are priorities, Olympus pushes the needle forward - but with confirmation bias against larger sensors.

Autofocus and Shooting Speed: Chasing Subjects When It Counts

Both cameras use contrast-detection autofocus systems - standard fare for their class and release era. Neither has phase-detection points or hybrid AF, so don’t expect lightning-fast or universally reliable autofocus.

Canon’s AF features include face detection and a single focus point with tracking. Olympus adds touch-to-focus as well, which can aid quick subject acquisition especially when the touchscreen is enabled.

Continuous shooting rates expose their intended user base:

• Canon: 4 frames per second (fps)
• Olympus: 7 fps

Those numbers look good on paper, but real-world sustained burst speeds are slightly lower due to buffer constraints. Olympus’s faster burst rate makes it more appealing for snapping moderate action bursts in wildlife or casual sports.

Neither camera makes bold promises on AF tracking accuracy for high-speed subjects - if you’re chasing fast birds or fast-paced action, neither camera is ideal but Olympus still edges Canon with its faster fps and responsive touchscreen AF point selection.

Zoom Power and Image Stabilization: Getting Closer Without the Shakes

A superzoom is only as good as its reach and how steady it is in your hands.

• Canon SX510 HS sports a whopping 30x zoom range (24–720mm equivalent), outgunning Olympus’s 24x zoom (25–600mm equivalent). That extra reach can be a game-changer for wildlife or distant architectural details - but only if the lens is sharp and the system stable.

• Olympus SZ-31MR compensates with sensor-shift 5-axis image stabilization versus Canon’s traditional optical stabilization.

In practice, Canon’s longer zoom introduces more noticeable handshake beyond 400mm equivalent, making steady shots tricky without support. Olympus’s sensor-shift stabilization was surprisingly effective, allowing sharper handheld shots even at full zoom or slower shutter speeds.

However, Olympus’s longer maximum aperture at telephoto (f/6.9 vs f/5.8 on Canon) means less light and potentially more noise or slower shutter speeds in low-light telephoto shooting.

Neither camera’s lens delivers razor-sharp detail edge to edge at the extremes of the zoom range but results are usable if you stop down a bit and steady your stance.

Let’s Talk About the Flashes and Low-Light Support

In-camera flashes are rarely the hero of your photography story, but sometimes necessary.

Canon’s built-in flash covers up to 5 meters, whereas Olympus’s flash can reach as far as 9.3 meters in ideal conditions - a significant difference that can matter in backyard portraits or dim events.

Both offer various flash modes including red-eye reduction and slow sync, but Canon’s gives you a bit more manual exposure control overall, consistent with its more advanced modes.

Low-light shooting beyond flash usage slightly favors Olympus due to better ISO headroom and stabilization, but image noise and softness remain issues above ISO 800 on either camera.

Video Capabilities: A Quick Look at What You’ll Capture Beyond Stills

While these cameras aren’t designed as video powerhouses, they do offer respectable HD recording.

• Canon offers 1080p video at 24 fps, which is good cinematic frame rate but may feel slightly choppier for fast action.
• Olympus opts for 1080p at 30 fps, smoother for casual recording, plus a touchscreen interface to start/stop recording and shift focus.

Neither has microphone or headphone ports, so audio options are limited to internal mics, which is par for the course but a noticeable limitation for serious vloggers.

Battery Life and Connectivity: Long Hauls or Easy Sharing?

Canon’s NB-6LH battery yields roughly 250 shots per charge; Olympus’s LI-50B offers about 200 shots. This modest battery endurance suggests carrying spares for longer sessions or vacations.

On the wireless front, Canon includes built-in Wi-Fi for straightforward wireless image transfer and remote capture via apps. Olympus counters with Eye-Fi card compatibility, enabling wireless transfers but requiring an Eye-Fi SD card - a bit more cumbersome.

Both cameras offer USB 2.0 and HDMI outputs for tethering or playback. No Bluetooth, NFC, or GPS are present, which you might expect given their older release dates.

Durability and Build: Are These Cameras Going to Survive Your Adventures?

Neithercamera features weather sealing, dustproofing, or shock resistance. Their plastic bodies feel sturdy for everyday traveling but won’t stand rough treatment or harsh environments.

If you plan on serious outdoor shooting in demanding conditions, these cameras require careful handling or protective cases.

Seeing the subtle differences in skin tones, textures, and dynamic range can clarify the specs vs reality gap.

• Portraits: Canon’s warmer color science renders skin tones with pleasant warmth, though sometimes slightly softer details and less pop in shadows.
• Landscapes: Olympus’s higher resolution and dynamic range show more detail in highlights and shadow recovery, though sometimes at the cost of slight color coolness.
• Wildlife: Canon’s extended zoom gives an advantage but Olympus’s quicker focus and higher fps makes capturing fleeting moments marginally easier.
• Macro: Olympus came closer to subjects (down to 1 cm) than Canon could - very useful for flowers or small objects.
• Night/astro: Both struggled at ISO above 1600 with noise artifacts; Olympus had a slight edge thanks to sensor tech.

How Do They Score Overall and By Photography Type?

Performance charts from testing reveal:

• Canon’s strength is in versatility and manual control options - better suited to photographers ready to tweak and experiment.
• Olympus excels in user friendliness, higher resolution, and quicker operation - ideal for casual shooters wanting a solid all-rounder.

Final Thoughts: Which Camera Fits Your Needs?

So after sizing up both contenders in this superzoom compact duel, who takes the crown?

Choose the Canon SX510 HS if you:

• Want longer zoom reach - those extra 120mm on the telephoto end really extend your creative framing options.
