Canon SX40 HS vs Casio EX-FH100: A Hands-On Comparison of Two Small-Sensor Superzooms

When stepping into the fascinating realm of versatile “bridge” and compact cameras packed with monstrous zooms, the Canon PowerShot SX40 HS and the Casio Exilim EX-FH100 have often caught enthusiasts’ eyes - not least because both promise a generous zoom range and a pocket-friendly price point. Yet these two from the early 2010s represent subtly different philosophies in compact telephoto photography. After extensive hands-on testing and shooting sessions, here’s what I’ve found when putting them head-to-head on everything from crisp portraits to ferocious wildlife action, creative macro shots, and beyond.

Let’s unpack how these cameras fare in practical use, leveraging detailed specs, image tests, and real-world experience - arming you with the nuanced insights you actually need before making that purchase.

Getting to Know the Players: Form and Feel

Before diving into pixels and processors, starting with the cameras’ physicality is always revealing. Ergonomics, build quality, and size heavily influence your shooting comfort, especially during long outdoor sessions.

The Canon SX40 HS is a true “bridge” camera - thinking DSLR-inspired - with a robust, hefty physique weighing 600 grams and measuring 123×92×108 mm. Holding it feels gratifyingly solid and well-balanced, thanks to its pronounced handgrip and thoughtfully placed dials. This camera screams “I mean business,” especially for those preferring tactile control over menus. Meanwhile, its fully articulated 2.7-inch screen offers flexible angles for shooting at challenging perspectives or live-view framing.

The Casio EX-FH100, conversely, embraces compactness and portability. Weighing in at a feather-light 201 grams and remarkably petite dimensions of 104×60×28 mm, it is unmistakably portable and ideal for carry-on-the-go street or travel photography. The lack of a viewfinder (electronic or optical) nudges you into relying on its fixed 3-inch rear LCD, which - while larger than Canon’s - does not articulate.

Both cameras sport a fixed lens - no swapping out here - but with very different zoom ranges: Canon’s mighty 24-840mm equivalent (35x zoom!), against Casio’s more modest but still impressive 24-240mm (10x zoom).

This size and build contrast will immediately steer your decision if you prefer something pocketable versus an all-day handheld workhorse.

Sensor and Image Quality: The Heart of the Matter

Both the Canon SX40 HS and Casio EX-FH100 feature a 1/2.3-inch backside-illuminated CMOS sensor - fairly standard for superzoom compacts - measuring 6.17×4.55 mm with a sensor area around 28.07 mm². Canon scores 12 megapixels; Casio opts for 10 MP.

While these small sensors inherently limit dynamic range and high ISO performance compared to APS-C or full-frame giants, their BSI technology (backside illumination) helps gather light efficiently, improving low-light capability marginally.

In my tests, Canon’s SX40 HS benefits from its more refined DIGIC 4 image processor (absent explicit processor info on Casio), yielding slightly cleaner images with better noise control up to ISO 800. The Casio EX-FH100’s sensor and JPEG processing tend to produce somewhat softer images - probably owing to slightly fewer effective megapixels and more aggressive noise reduction - though it still holds up well under daylight conditions.

Color depth and tonal gradations are fairly similar, apparent when shooting outdoor scenes, but Canon's tendency towards punchier saturation often rewards portrait skin tones and landscapes with more vibrancy.

Keep in mind, neither camera offers RAW support in Canon’s case, whereas Casio can shoot RAW - this could sway professionals wanting maximum post-processing flexibility despite the sensor limitations.

Mastering Controls and User Interface: Intuitive or Industrial?

Camera interaction defines your shooting enjoyment just as much as image results. The Canon SX40 HS sports a rich command set - shutter priority, aperture priority, manual exposure with easy access on the mode dial, and exposure compensation. I appreciated the ring around the lens to tweak zoom or manual focus, alongside dedicated buttons for ISO selection and AF modes. The 2.7-inch articulated screen, though on the small side, helped with framing tricky angles or video recording.

The Casio EX-FH100, reflecting its compact ethos, makes some compromises. Its fixed 3-inch LCD offers a touchscreen-less but clear display panel, which is friendlier than Canon’s tiny 230K-dot screen. However, it lacks an EVF, which may make bright daylight shooting more cumbersome. Manual exposure modes exist but are more buried in menu layers, making quick adjustments less fluid. The lens ring for focus was present as well, but no zoom ring - zooming happens via buttons.

I found myself gravitating towards Canon when rapid setting changes were needed, especially in wildlife or sports scenarios, whereas Casio serves better those who enjoy intuitive, point-and-shoot simplicity with a modest manual override.

Autofocus, Burst Shooting & Telephoto Pursuits: Catching the Moment

For wildlife and sports enthusiasts, autofocus (AF) responsiveness, tracking accuracy, and burst shooting matters a great deal.

The Canon SX40 HS offers 9 contrast-detection AF points with face detection enabled. Its continuous AF mode works fairly well in good light but falls behind fast phase-detection systems found in interchangeable lens cameras. Nonetheless, its precision in locking onto faces ensures reliable portrait and street shooting results. Burst shooting hits a robust 10 frames per second - impressive for a 2011 bridge camera - allowing capture of fast actions, though buffer length limits sustained shooting.

In comparison, the Casio EX-FH100 limits continuous shooting to 4 fps (single AF only) and relies solely on contrast-detection AF, with no face or multiple AF point support. This shows in wildlife shots, where AF hunting was more frequent and less efficient lock-on occurred. That said, Casio’s standout feature is its specialized high-speed video modes - offering remarkable 420 fps to 1000 fps slow-motion capture (albeit at lower resolutions) - great for creative motion study but less practical for standard sports.

Neither camera shines in low light autofocus - expect hunting under dim conditions.

Zoom Lens Performance: Reach and Versatility

Canon’s 24-840mm equivalent lens is a bona fide beast for a fixed zoom, covering ultra-wide to super-telephoto - a rarity and major selling point. The max aperture range (f/2.7–5.8) is generous enough at wide angles but tapers as you zoom in, producing handheld challenges at max zoom without a tripod unless ISO is cranked.

Casio’s 24-240mm lens offers a smaller, lighter zoom range at 10x. Aperture range f/3.2–5.7 is slightly narrower but roughly comparable when factoring in the shorter max reach. This shorter zoom impacts versatility for wildlife or extreme telephoto shots but adds to compactness.

Image sharpness across focal lengths favors Canon, especially mid-zoom, and the presence of Canon’s Optical Image Stabilization (OIS) lends steadiness on long reach shots. Casio uses sensor-shift stabilization, which is effective but less consistent at extended telephoto ends.

Capturing Portraits: Skin Tones, Bokeh, and Eye Detection

For portraits, Canon’s better color rendition and face detection AF put it ahead. The 9-point AF with face-priority means locking on quickly to eyes or faces for sharp results. Bokeh quality is, predictably, limited by the sensor and lens aperture, but the SX40 HS manages smoother background blur at wider apertures.

Casio’s EX-FH100 lacks face or eye detection, complicating sharp focusing on subjects in busy scenes. Its smaller maximum aperture and shorter zoom limit bokeh effectiveness, resulting in more “flat” backgrounds.

Canon thus edges portrait shooters looking for natural skin tones and selective focus.

Landscape Photography: Dynamic Range and Resolution

Landscape lovers will want good resolution and dynamic range to pull detail from shadows and highlights.

Both cameras are limited by the small sensor's dynamic range, about 10–12 stops, typical at their release. Neither being RAW on Canon reduces latitude in post-processing. Casio supports RAW but the difference was marginal in practice due to sensor constraints.

Canon’s 12 MP sensor edges out with slightly crisper detail and more defined edges in sample images. The articulating screen assists in composing complex landscape shots, such as low angles amid waterfalls.

Neither camera boasts weather sealing, so caution in the field is required.

Macro Photography: How Close Can You Get?

Macro performance is close but with subtle edges.

Canon can focus practically “from zero cm,” meaning the lens can be placed right up to subjects without losing sharpness, great for flowers or insects. The SX40 HS supports manual focus, aiding tricky macro work.

Casio’s minimum macro focusing distance is 7 cm, still decent but less flexible for extreme close-ups. Both have optical stabilization, helping handheld macro.

Night and Astrophotography: Pushing the Limits

At high ISO, noise is the main antagonist.

Canon’s SX40 HS manages up to ISO 1600 usable with noise tolerances for casual low light. Its longer shutter speed range (up to 15 seconds) accommodates some night modes, but fixed lens aperture limits star field capture.

Casio maxes at ISO 3200 but with noisier results and a max shutter speed of 4 seconds - restrictive for astrophotography.

Neither camera features built-in bulb mode or extensive night features.

Video Capabilities: Shooting Motion with Style

For videographers, Canon’s SX40 HS records Full HD 1080p at 24 fps, using MPEG-4 and H.264 codecs. It lacks a mic port, limiting external audio options. Its optical stabilization helps smooth handheld footage.

Casio’s video maxes at 720p 30 fps, which is less sharp but follows through with fascinating ultra slow-motion modes - 720 fps to 1000 fps at low resolution - that open creative niches for action analysis or artistic effects.

Neither camera offers 4K or professional video features, so these are entry-level tools.

Travel Photography: Versatility and Battery Life

On the road, carry weight, battery endurance, and flexibility are king.

The Canon SX40 HS’s heft and size make it a bulkier companion; 380 shots per charge is decent but extra batteries advisable for day trips. Its versatile zoom makes it a one-camera-outfit.

Casio’s smaller size and light weight greatly reduce pack bulk, but shorter zoom and fewer manual controls limit creative reach. Battery life data is sparse but likely similar.

Professional Usability: Limitations and Workflow Fit

Neither camera targets professional users. Lack of RAW on Canon and modest sensor size are key drawbacks. Casio’s RAW support and unique slow-motion add niche value, but build quality and AF limits discourage heavy professional use.

The Final Scores: Where Do They Shine and Falter?

After rigorous practical testing paired with detailed spec analytics, here’s an at-a-glance performance summary.

Breaking down strengths by photographic genres:

• Portraits: Canon’s face detection and color profiles dominate.
