Canon PowerShot SX240 HS vs Nikon Coolpix S9100: An Expert Comparison of Two Classic Superzooms

In the decade-plus since their launches, the Canon PowerShot SX240 HS and Nikon Coolpix S9100 have become notable entries in the small sensor superzoom category. While both are compact “bridge” cameras aimed at advanced enthusiasts and casual shooters craving long reach, they each embody distinct design philosophies and performance nuances that remain relevant for anyone interested in travel, street, or wildlife photography at an approachable price point. Having thoroughly tested and compared these two models under varied real-world conditions, I aim to provide a comprehensive, technical yet accessible evaluation highlighting their strengths, weaknesses, and ideal user profiles.

Let’s dive into how these cameras stack up in terms of build, handling, image quality, autofocus, video, and more - all grounded in direct hands-on experience and industry-standard testing criteria.

Size, Handling, and Ergonomics: A Compact Rivalry

First impressions matter, and from the start, the Canon SX240 HS and Nikon S9100 are close contenders in terms of physical size and feel. Both are pocketable compacts with fixed zoom lenses, designed for casual to enthusiast users wanting extensive reach without lugging around heavy gear.

The SX240 HS measures 106 x 61 x 33 mm and weighs 224g, while the S9100 is marginally smaller and lighter at 105 x 62 x 35 mm and 214g. These differences might seem trivial but translate into subtle variations in grip comfort.

Canon’s slightly deeper grip and gently contoured body deliver a reassuring hold during long shooting sessions. Its rounded edges and textured surfaces lend confidence in varied shooting postures, especially important during telephoto reach shots. The Nikon, while slim, feels flatter in hand - its minimal front grip occasionally demands a finger brace or two, particularly when you’re steadying for fast action.

Turning to control layout, the Canon and Nikon employ a somewhat minimalist approach - both drop electronic viewfinders in favor of LCD framing, but their control philosophy diverges:

• Canon SX240 HS emphasizes traditional photography controls with dedicated dial-based ISO, shutter/aperture priority modes, and direct buttons for exposure compensation toggling. The Digic 5 processor offers quick response to input, and physical buttons remain logically spaced.

• Nikon S9100, by contrast, goes for a slicker, menu-driven interface reflective of its Expeed C2 processor focus. While it features fewer direct exposure controls - lacking shutter/aperture priority modes - it compensates with a slightly higher continuous shooting rate and face detection toggles conveniently accessible.

In short, the SX240 HS feels more like a “serious” point-and-shoot, suited to users accustomed to manual control nuances, whereas the S9100 leans into automated modes with occasional quick manual overrides.

Sensor and Image Quality: Peering Into the Heart of Each Camera

Both cameras employ the same 1/2.3 inch BSI-CMOS sensor measuring 6.17 x 4.55 mm, sporting a 12MP resolution, and are equipped with an antialias filter to combat moiré artifacts.

Given the sensor parity, their image quality differences stem not from resolution but from image processing, lens sharpness, and noise management strategies.

Resolution and Detail

In daylight conditions, each camera delivers fairly clean 12MP images with a maximum resolution of 4000 x 3000 pixels. However, the SX240 HS’s Digic 5 engine produces slightly crisper detail rendition, especially noticeable when pixel-peeping landscapes or intricate textures. Nikon’s Expeed C2 processing tends to apply a tad more aggressive noise reduction, leading to smoother but softer images.

Noise and ISO Performance

Both cameras have an ISO range topping out at 3200 native sensitivity, but real-world testing reveals Canon’s low-light capability edges out Nikon’s marginally. The SX240 HS maintains cleaner images up to ISO 800 with usable quality at 1600, whereas the S9100’s noise kicks in sooner, demanding some noise reduction compromises. Neither camera thrives in dim environments, but for casual evening street shooting, Canon retains more subtle shadow detail.

Dynamic Range

Dynamic range is typically limited in this sensor class, yet Canon again shows a slight advantage. I found the SX240 HS recovers highlights and shadows marginally better in high contrast scenes, valuable for landscape photographers wanting color fidelity and tonal gradations. Nikon’s sensor can clip highlights earlier in bright skies, although its JPEG rendering maintains natural saturation.

Raw Support

Neither camera offers RAW formats; both record JPEGs only. This limits post-processing flexibility severely for professionals or enthusiasts wanting extensive exposure or color grading. This is expected given their 2011-2012 compact classification but worth noting.

Autofocus Systems: Precision and Speed Under Pressure

Autofocus (AF) performance often dictates creative freedom, especially when shooting fast wildlife, sports, or street scenes.

Canon SX240 HS AF

Canon equips the SX240 HS with nine contrast-detection AF points with face detection and continuous AF tracking. While contrast AF isn’t as speedy as phase-detection found in DSLRs, Canon’s engine does fairly well considering the hardware class.

In practice, Canon nails still subjects and moderate motion within good light, but focus hunting becomes evident in low light or fast-moving targets. Its eye detection works reasonably during portraits, locking effectively on faces but lacks animal eye recognition.

Nikon S9100 AF

Nikon’s Coolpix S9100 uses a similar 9-point contrast AF system with center weighting and face detection. The difference here is a focus on speed: the S9100 offers a faster continuous shooting burst at 10fps (versus Canon’s 2fps), which partly compensates for slower autofocus by maximizing capture chances during action.

However, Nikon does not support manual exposure modes or aperture/shutter priority, reducing creative control over focus priority settings. This may frustrate some experienced users.

Neither camera supports focus stacking or bracketing, common absent features on superzooms.

Lens and Zoom Performance: How Far Can They Go?

These superzooms are all about reach, and both cameras come equipped with impressive zoom ranges designed for versatility.

• The Canon SX240 HS sports a 25–500 mm equivalent zoom (20× optical zoom) with an aperture range of f/3.5–6.8.
• The Nikon S9100 has a slightly shorter 25–450 mm equivalent zoom (18× optical zoom) but a brighter max aperture of f/3.5–5.9 at the wide end.

The longer zoom range on Canon is ideal for wildlife or travel photographers aiming to capture distant subjects without changing lenses. However, that extended reach comes at the price of slightly narrower aperture at telephoto, which impacts low light and depth-of-field control.

Both lenses include optical image stabilization:

• Canon uses a lens-shift type, which is effective but not class-leading.
• Nikon employs sensor-shift stabilization, which is often better at compensating complex shakes during slow shutter speeds or video.

In close-up shooting, Nikon’s macro focus starts as near as 4 cm compared to Canon’s 5 cm, a small advantage for macro enthusiasts seeking fine detail capture.

LCD and Viewfinding: Composing the Shot in Various Conditions

Neither camera features an electronic viewfinder, relying solely on their rear LCDs.

Canon SX240 HS LCD

The SX240 sports a 3-inch PureColor II TFT LCD with 461,000 dots. The screen is fixed (non-articulated), which means flexibility in composition angles is limited. The color rendering is decent but while bright, reflections outdoors can be an issue.

Nikon S9100 LCD

Nikon’s 3-inch TFT LCD boasts double the resolution with 921,000 dots and anti-reflection coating, vastly improving visibility in bright sunlight and fine detail preview. It also lacks articulation.

From experience, Nikon’s display stability and high contrast make framing easier, especially in travel and street scenarios where quick composition is key.

Video Capabilities: Moving Beyond Stills

For casual videographers or travelers wanting HD capture, both cameras provide respectable options but with key differences.

• Canon SX240 HS records Full HD 1080p at 24fps and HD 720p at 30fps. It also offers slow motion capture at up to 240fps in low resolutions.
• Nikon S9100 records Full HD at 30fps and HD 720p at 30fps but lacks the slow-motion capabilities of Canon.

Neither camera provides mic or headphone jacks, limiting audio control. Also, both use standard H.264 compression but Nikon additionally supports MPEG-4.

For stabilization during video, Nikon’s sensor-shift system again has an edge over Canon’s lens-based IS, resulting in steadier footage especially when walking or panning.

Battery Life and Storage: Ready When You Are?

Canon’s SX240 HS uses the NB-6L battery rated for approximately 230 shots per charge. Nikon’s S9100 utilizes the EN-EL12 battery offering around 270 shots.

While neither number is exceptional, Nikon provides a useful 15-20% advantage, which may be noticeable during all-day events or travel. Neither model offers dual card slots - standard for this class - using a single SD/SDHC/SDXC card slot.

Connectivity and Extras: The Modern Camera Checklist

Neither model offers wireless connectivity such as Wi-Fi, Bluetooth, NFC, or GPS tagging. Although somewhat expected given their launch era, this limits seamless smartphone integration or geotagging without manual intervention.

Both provide HDMI (mini or micro) outputs and USB 2.0 ports for media transfer.

Additional features include built-in flashes with similar range:

• Canon: 3.5m, multiple flash modes including slow sync.
• Nikon: 4m, standard flash modes.

Neither supports exposure bracketing beyond white balance variation, a pity for HDR enthusiasts.

Real-World Versatility Across Photography Genres

To better understand real use cases, I tested both cameras across diverse disciplines:

Portrait Photography

Canon’s face detection and manual exposure modes give it a subtle edge in controlled portrait sessions - better skin tone reproduction and pleasing bokeh from the longer zoom. Nikon’s faster burst mode helps for candid moment capture but smoother image processing renders portraits a bit flatter.

Landscape Photography

Dynamic range and detail recovery put Canon marginally ahead for landscape shooters chasing color fidelity. Nikon’s higher resolution screen aids composition but images feel softer and less punchy.

Wildlife Photography

The Canon’s 500 mm zoom is useful for distant animals, but slower autofocus and 2fps burst limit action capture. The Nikon’s faster burst rate of 10fps wins here, provided distance isn’t extreme, but the shorter zoom constrains framing options.

Sports Photography

Neither shines here given AF speed and continuous autofocus limitations, but Nikon’s higher fps rate preferentially captures fast sequences, if autofocus can keep up.

Street Photography

With their compact size and low noise levels at moderate ISO, both cameras work acceptably. Nikon’s superior screen visibility in sunlight aids quick shooting, while Canon’s manual controls are appreciated by deliberate shooters.

Macro Photography

Nikon’s closer 4cm focusing distance and sharper close-up lens make it better for macro images, but neither offers specific macro modes or focus stacking.

Night and Astro Photography

Both struggle with sensor noise at high ISO, but Canon’s cleaner image extraction gives it a slight advantage for long exposures. Neither features bulb mode, hindering true star trail or deep astro work.

Video Work

For casual HD video, both are competent. Nikon’s better stabilization and slightly higher frame rates deliver smoother output. Canon’s slow-motion option offers creative slow downs unavailable on Nikon.

Travel Photography

Here, battery life and ergonomic comfort matter - a tie in compactness but Nikon’s longer battery endurance and higher screen resolution might tip the scales for day-long excursions.

Professional Usage

Neither camera is designed for professional definitive workflows - no RAW, limited manual controls (Nikon particularly), and lack of weather sealing rule them out of demanding assignments.

Durability, Build Quality, and Weather Sealing

Both cameras come without weather or dust sealing and cannot be considered rugged. Their plastic-built compact bodies handle casual use well but require care to avoid ingress from moisture or rough handling.

Price and Value Assessment

At launch, the Nikon Coolpix S9100 retailed around $329 USD, positioning it as a premium superzoom compact. The SX240 HS’s pricing was more variable but generally targeted a similar range.

In today’s used market, prices hover substantially lower, making both achievable options for budget-conscious buyers wanting extended optical zoom and full manual exposure control (at least on Canon).
