Canon SX40 HS vs Samsung WB750: The Ultimate Superzoom Showdown From an Experienced Photographer’s Lens

When it comes to superzoom cameras, few categories excite enthusiasts more than “small sensor superzooms,” those compact yet versatile cameras packing long zoom ranges in manageable bodies. I’ve spent years testing cameras with this form factor - and today I’m putting the venerable Canon PowerShot SX40 HS head-to-head with the compact Samsung WB750. Both hailed from the early 2010s but still turn heads for travel, nature, and casual shooting. Which one deserves your hard-earned cash? Let’s dive into a thorough, hands-on comparison that blends technical analysis with practical experience.

How Big Is Big? Physical Design and Handling

First off, size and ergonomics matter a lot for superzoom cameras. Neither of these contenders are tiny - but their designs cater to different grips and portability preferences.

The Canon SX40 HS carries a classic “bridge” style, resembling a compact DSLR with a pronounced grip and a chunky body (123×92×108 mm, weighing 600g). This makes it comfortable for extended shooting especially with longer focal lengths - important for wildlife or sports where stability counts.

The Samsung WB750, by contrast, is markedly more compact and lightweight (105×59×25 mm, 193g), closer to a traditional point-and-shoot feel. It slips easily into a jacket pocket or small bag and suits street or travel photographers prioritizing discretion and portability.

Ergonomically, the SX40’s DSLR-like body offers more space for well-placed buttons and dials, while the WB750 keeps things minimalistic. If you ask me, because of the SX40’s thoughtful grip and more substantial heft, I found it steadier during long zoom telephoto use, even without a tripod. The WB750’s slim design favors grab-and-go casual shooting or travel where packing light is key.

Control Surfaces and User Interface: More Than Meets the Eye

Beyond size, button layout, screen usability, and viewfinder quality influence how intuitively you can operate your camera, especially in fast-paced or changing conditions.

Looking down from above, the Canon SX40 HS showcases a better-organized control scheme with dedicated dials for aperture, shutter speed, mode selection - features any enthusiast will appreciate. It even offers full manual exposure modes alongside aperture and shutter priority, control options you’ll want if you plan to grow as an impatient learner moves toward serious photography.

The Samsung WB750 is simpler, with more limited manual control (manual focus yes, but no manual exposure adjustments beyond basic exposure compensation), and no viewfinder at all. The absence of any EVF hurts usability in bright daylight or when shooting at eye level, relying solely on the fixed 3-inch rear LCD.

Speaking of which: the Samsung’s LCD screen is notably larger and crisper (3" at 460k dots) versus the Canon’s 2.7" display with a lower 230k-dot resolution.

However, Canon’s fully articulated LCD screen offers compositional freedom in awkward angles or tripod setups - something I miss badly when restricted to Samsung’s fixed screen. For me, when shooting macro or awkward wildlife angles, that articulation removes a lot of strain.

Personally, I prefer the Canon’s button layout and the option of an electronic viewfinder (albeit without data overlay) for more stable framing, but if you prize a bright, sharp screen and an ultra-compact body, Samsung wins this round.

Sensor Size, Resolution, and Image Quality: The Heart of the Matter

Both cameras use a 1/2.3” Backside Illuminated CMOS sensor measuring 6.17×4.55 mm with around 28mm² surface area.

The SX40 HS sports a 12MP sensor, while the Samsung WB750 edges slightly ahead at 13MP - but the difference is negligible in practice given sensor size constraints. Neither camera shoots RAW, which means image quality is tightly tied to JPEG processing pipelines - where Canon’s longstanding expertise often gives it a polish advantage.

In controlled tests, I observed that both excel in good daylight, producing detailed 4,000×3,000 pixel images with relatively crisp textures out to mid-zoom. However, when pushing ISO beyond 400, noise becomes quite visible, as expected from small sensor superzooms dating back to 2011.

Canon’s chip showed slightly better noise handling and color rendering subtlety, especially in skin tones and greens. Samsung’s colors appeared a bit punchier, which some users might prefer for direct social sharing though less naturalistic.

For landscape - where dynamic range matters - both fall short of modern mirrorless cameras but manage respectable midtones; the SX40 had a slight edge in highlight preservation under tricky sunlight.

Autofocus and Focusing Performance: Speed, Accuracy, and Usability

Autofocus (AF) is often the unsung hero or villain of superzoom cameras.

The Canon SX40 HS features 9 autofocus points with contrast detection and offers facial recognition - a boon for moving subjects or portraiture. It supports continuous AF during burst shooting, which aids wildlife or sports enthusiasts.

By comparison, the Samsung WB750’s AF system is more rudimentary, relying on contrast detection with unspecified points, no continuous AF, but it does incorporate some AF tracking functionality. Crucially, Samsung lacks face-detection AF in live view mode, which can slow things down when shooting unpredictable subjects.

In real-world use, Canon’s AF was noticeably faster and more reliable locking onto eye-level subjects or birds in flight - especially in decent light. The SX40’s AF system shows you more control and predictability, which photographers will appreciate for portraits and action shots.

Samsung’s AF felt sluggish and occasionally hunted even in bright outdoor light; in low light, both struggled but Canon again coped better due to its larger lens aperture at the wide end (f/2.7) and optimized AF algorithms.

Zoom Ranges and Lens Performance: Reach vs Versatility

Two superzoom cameras are of course judged first by zoom capability.

• Canon SX40 HS: 24mm to 840mm equivalent (35x zoom), f/2.7-5.8
• Samsung WB750: 24mm to 432mm equivalent (18x zoom), f/3.2-5.8

The Canon offers nearly double the telephoto reach without stepping beyond a small sensor budget.

You can see why this matters: capturing distant wildlife or sports events becomes feasible on the SX40 where the WB750’s 432mm max reach might require cropping and compromise image quality.

Optical image stabilization is present in both, helping to keep shots steady at long focal lengths, but Canon’s slightly brighter lens at the wide end and longer range means I preferred it for handheld telephoto use.

That said, Samsung’s shorter zoom means less optical distortion and slightly sharper images at the telephoto end owing to fewer compromises in lens design - a classic tradeoff.

Burst Shooting, Shutter Speeds, and Shooting Modes

Both cameras offer continuous shooting speeds of roughly 10 frames per second, respectable for the category and era.

SX40 HS has a broader shutter speed range (up to 1/3200s max) compared to Samsung’s 1/2000s limit, offering more flexibility in bright light or wide apertures.

The Canon also packs in advanced exposure modes (shutter/aperture priority, full manual), bracketing for white balance, and more extensive flash controls including external flash compatibility. Samsung’s flash is internal only, with fewer modes.

No intervalometer or timelapse recording on either camera.

Video Capabilities: Not Just Stills

Video has become a vital feature on any camera, and here both deliver Full HD recording.

• Canon SX40 HS: 1920×1080 up to 24fps, with MPEG-4 and H.264 codec
• Samsung WB750: 1920×1080 up to 30fps, with similar codecs

The Samsung edges out a bit in frame rate at Full HD, which could yield smoother motion for casual video.

However, neither offers microphone or headphone jacks, limiting professional audio recording options.

Both cameras have optical stabilization during video, but the Canon’s longer zoom range adds a potential advantage for diverse framing.

No 4K or high frame rate super slow motion modes on either, unsurprising given the release years.

Battery Life and Storage Options

In the endurance arena, the Canon SX40 HS uses a proprietary NB-10L battery rated for ~380 shots per charge - a solid number though not exceptional by today’s standards.

The Samsung WB750, with its smaller form, uses the SLB-10A battery, but official battery life specs are harder to find; expect fewer shots given the compact body and higher resolution LCD demanding more power.

Both cameras use a single SD/SDHC/SDXC card slot.

Connectivity and Extras

Connectivity-wise, the Canon SX40 HS offers Eye-Fi card compatibility (Wi-Fi via SD card) and HDMI output - nice for both file transfer and quick TV playback.

Samsung WB750 lacks wireless features but likewise includes HDMI and USB 2.0 ports.

Neither supports Bluetooth, NFC, or GPS tagging.

Durability and Weather Resistance

Neither camera offers any environmental sealing or extra durability features. Neither are waterproof, dustproof, shockproof, or freezeproof.

So if rugged outdoor use under adverse conditions is your priority, you’ll want to look elsewhere or add protective cases.

Real-World Photography Discipline Performance: What This Means For You

How do these cameras hold up beyond specs? Let’s review genre by genre, incorporating my extensive practical tests:

Portrait Photography: Skin Tones and Bokeh

Thanks to Canon’s wider wide-angle aperture (f/2.7 vs f/3.2), the SX40 HS produces slightly smoother background blur and better subject isolation at shorter focal lengths. Its face detection AF locks onto eyes with greater consistency, vital for sharp portraits.

Samsung’s WB750, with no continuous AF and a smaller max aperture, struggles to produce creamy bokeh or reliable focus on moving subjects.

Verdict: Canon wins for portraits if you’re after classic results and AF precision.

Landscape Photography: Resolution and Dynamic Range

While both cameras have similar 12-13MP sensors, Canon’s superior dynamic range handling lends to more detail capture in bright skies and shadows.

Neither offers weather sealing, but Canon’s articulated screen helps compose tricky low-angle shots.

Verdict: Canon slightly favored for landscapes.

Wildlife Photography: Zoom Reach and Autofocus

The Canon SX40 HS reigns with its monumental 840mm zoom - critical for distant subjects - and faster AF tracking capabilities.

Samsung’s 432mm zoom is less versatile here, and its slower, less responsive AF makes action shots challenging.

Verdict: Canon clearly better for wildlife shooters.

Sports Photography: Burst Rates and Tracking

Both offer 10fps burst, but Canon’s continuous AF during bursts is superior to Samsung’s single-shot AF, making the SX40 HS more adept at capturing fast-moving athletics.

Street Photography: Discretion and Portability

Samsung’s compact body and lighter weight make it more comfortable and less conspicuous in urban environments.

Canon’s larger size hinders spontaneity but offers greater reach if you want to capture long-distance street portraits or details.

Macro Photography: Close Focusing and Precision

Samsung supports 5cm macro focusing, Canon effectively zero cm focus distance (officially 0cm macro) meaning both can capture close subject details, but Canon’s articulated screen makes framing easier in tight spots.

Night and Astro Photography: ISO and Exposure

Neither camera shines in high ISO performance - both max out at 3200 with noisy results. Canon has a slight edge in low-light clarity and exposure flexibility (shutter speed up to 1/3200s).

Neither camera offers bulb mode or advanced astro features.

Video Usage

Samsung’s smoother 1080/30p video might feel better for casual clips, but Canon’s longer zoom adds creative framing options.

Lack of audio inputs limits serious videography on either camera.

Travel Photography: Versatility and Convenience

Here, both cameras are compelling options:

• Choose Samsung WB750 if you prioritize light weight and pocketability. Great for trips with minimal gear.

• Choose Canon SX40 HS if you want all-in-one zoom reach and manual control but don’t mind the size or weight.

Professional Use and Workflow Integration

Neither camera supports RAW capture or pro-level tethering - both aimed at enthusiast and semi-pro markets.

Canon’s exposure controls and external flash support offer slightly better integration into advanced workflows.
