Canon SX40 HS vs Fujifilm X-S1: An In-Depth Comparison of Two Small Sensor Superzoom Giants

When Canon announced the PowerShot SX40 HS in September 2011 and Fujifilm introduced its X-S1 a couple of months later, they both aimed squarely at the enthusiast bridge camera market. These models - both featuring fixed superzoom lenses, DSLR-style ergonomics, and loaded with features - offer options for photographers seeking versatility without the bulk of interchangeable lenses. But which camera truly excels when put through the wringer of real-world use?

Over many hours testing these two cameras, I engaged deeply with their strengths and quirks across multiple photographic disciplines. In this comprehensive 2500-word comparison, I’ll walk you through their sensor performance, autofocus, handling, lens quality, and more - mixing technical analysis with practical experience to help you pinpoint the right choice for your creative needs.

Let’s start by taking a look at their physical presence and ergonomics, a critical factor in long shooting sessions and travel.

Size and Ergonomics: Handling the Giants in Your Hands

When it comes to bridge cameras, size and ergonomics often make or break user experience - especially for travel and street photographers who need nimble gear.

The Canon SX40 HS measures a compact 123x92x108 mm and weighs about 600 grams, while the Fujifilm X-S1 is noticeably larger and heavier at 135x107x149 mm and 920 grams. This size difference is tangible. Holding the SX40 HS, I found its lighter weight and smaller footprint less fatiguing over long shoots. It sits comfortably in hand with a modest but secure grip.

The X-S1, on the other hand, feels solidly built - indeed, its heft communicates a sense of durability that might reassure professionals who shoot extensively outdoors. However, when handholding for extended periods, the extra weight could tire some users, especially those not accustomed to heavier bridge cameras.

The Canon’s articulating 2.7" screen (230k dots) enables flexible framing from odd angles, a boon for macro or creative portraiture. Fujifilm offers a slightly larger 3" tilting screen with double the resolution (460k dots), providing richer detail and easier composing in bright environments, though it lacks full articulation that swing out for selfies. If you frequently frame at waist or overhead levels, the Canon might edge out here, but the X-S1’s screen clarity is notable.

Next, let's examine their control layouts and interface designs, which factor heavily into workflow fluidity.

Control Layout and User Interface: Where Intuition Meets Functionality

Navigating the menu system and physical controls quickly is essential when you’re shooting fast-paced subjects or changing settings on the fly.

Both models mimic DSLR ergonomics with prominent dials and buttons, yet their philosophy differs slightly. The Fujifilm X-S1 impresses with an “all-analog” interface - numerous physical controls for aperture, shutter speed (up to 1/4000s), ISO, and exposure compensation - a dream for photographers who prefer direct tactile input. Its dedicated front and rear control dials enable rapid manual adjustments, critical during challenging lighting or action scenes.

In contrast, the Canon SX40 HS offers a more conventional bridge camera layout with a mode dial and fewer dedicated controls, leaning more on its menu for less common settings. The max shutter speed here is slower (1/3200s), which might limit freezing very high-speed action under bright conditions.

The Canon’s fully articulated screen complements its touch interface absence, allowing live view framing flexibility, though the lack of touch limits quick focus point selection common in more modern cameras. Fujifilm compensates with a fully electronic viewfinder (100% coverage and faster refresh), which consistently provided clarity and precision during my tests, especially in bright sun.

On balance, Fujifilm’s X-S1 delivers a more professional tactile experience, whereas Canon keeps things simpler but less immediate. For users valuing quick hands-on adjustments, the X-S1 leads.

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

Now we dive into the essential foundation for image quality: the sensor.

Both cameras use 12MP BSI-CMOS sensors, but the sensor size is materially different. The Canon SX40 HS sports a 1/2.3” sensor measuring 6.17x4.55mm (28.07 mm²), whereas the Fujifilm X-S1 employs a much larger 2/3” sensor at 8.8x6.6mm (58.08 mm²) - over double the surface area.

That difference translates into superior light-gathering ability for the X-S1, leading to better dynamic range, color depth, and low-light performance. DxOMark scores confirm this: The X-S1’s sensor scores impressively with a color depth of 20.4 bits and dynamic range of 11.2 EV compared to the Canon’s untested but expectedly lower range given sensor size.

In practical terms, I noticed:

• Portraits: The X-S1 delivered richer skin tones with more natural gradation, while the SX40 HS tended to clip highlights under strong side-light, compromising detail in highlights.

• Landscape shots: The Fujifilm’s larger sensor captured better shadow detail and retained highlight information even in contrasting scenes like sunsets or forests, resulting in more editable RAW files.

• Low-light: The X-S1 has a max native ISO of 3200, with an extended boost to 12800 - though noisy above 3200, it’s still usable for casual night captures. The Canon is capped at ISO 3200 and exhibits more aggressive high ISO noise.

Both cameras output 12MP images at 4000x3000 resolution, which strikes a balance between detail and manageable file sizes for enthusiasts.

A key edge to the X-S1 sensor is also its support for RAW capture, absent in the Canon SX40 HS. This is crucial for photographers wanting the maximum post-processing latitude.

Autofocus Systems: Responsiveness and Accuracy on the Move

When I talk about autofocus in bridge cameras, two aspects matter most: speed and accuracy, especially for wildlife, sports, or street photography.

The Canon SX40 HS uses contrast-detection AF with 9 focus points, including face detection but no eye or animal detection. It delivers reasonably fast autofocus in good light but lags in continuous AF mode and low-light scenarios. Tracking moving subjects is challenging given the lack of advanced AF tracking algorithms.

The Fujifilm X-S1 steps up with 49 AF points, continuous AF with tracking, and face detection. In hands-on use, I found its autofocus substantially faster to lock focus and maintain it on moving subjects. For example, shooting birds in flight or children running around yielded higher keeper rates on the X-S1 thanks to predictive tracking.

Both cameras offer manual focus with focus peaking assistance, though Fujifilm's enhanced zoomed-views in live view make precise manual focusing easier.

In short: for action or wildlife shooters, the X-S1’s autofocus system is far superior, while the SX40 HS suffices for more static or controlled shooting.

Lens and Zoom: Reach, Sharpness, and Aperture

The hallmark of these fixed superzoom bridge cameras is their expansive focal ranges - but quality varies.

• Canon SX40 HS Lens: 24-840mm equivalent (35x zoom) with a max aperture range from f/2.7 (wide) to f/5.8 (tele).
• Fujifilm X-S1 Lens: 24-624mm equivalent (26x zoom) with a max aperture of f/2.8-f/5.6.

While the Canon offers a longer maximum reach, the Fujifilm trades some zoom length for a slightly wider max aperture at the long end, which helps in low light and when trying to isolate subjects with smoother background blur.

I tested sharpness across zoom ranges and found the Fujifilm lens delivers more consistent edge-to-edge sharpness at all focal lengths, especially in the mid-telephoto range (100-300mm). The Canon lens shows softer edges at extremes of the zoom but is reasonably sharp around 50-200mm.

Both incorporate optical image stabilization - a necessity to counteract shake at telephoto lengths. Stabilization works well on both, but the Fujifilm’s system feels more robust, allowing handholding at slower shutter speeds without pronounced blur.

Macro focusing capabilities slightly favor the X-S1 with a reach down to 1cm versus Canon’s theoretical 0cm macro distance (actually a bit less practical). This makes the Fuji a better candidate for close-up work.

Display and Viewfinder: Real-World Composition Tools

Viewing and composing images precisely can be tough on these cameras with relatively small screens and electronic viewfinders.

The SX40 HS’s 2.7" fully articulated PureColor II VA TFT LCD performs well, especially for tough framing angles, but its 230k-dot resolution looks a bit coarse by today’s standards. Outdoor visibility is acceptable but not stellar.

Fujifilm’s 3" tilting LCD panel impresses with double the resolution, delivering sharper live view monitoring, crucial for fine focus checks - especially in video or macro.

Both cameras offer electronic viewfinders (EVFs), but Fujifilm’s provides full 100% coverage with less lag, while Canon’s is lower resolution (not specified) and less bright. For fast action or shoot-from-the-hip style street photography, the X-S1’s EVF is a clear advantage.

Battery Life and Storage: Practical Considerations in the Field

The SX40 HS utilizes the NB-10L battery, rated for approximately 380 shots per charge, which is decent but might require a spare battery on long trips. The X-S1 uses the NP-95 battery; Fujifilm doesn’t specify official shot count, but in my testing, it provided roughly the same endurance.

Both cameras use SD/SDHC/SDXC cards and have single slots - standard practice but worth noting for professionals needing redundancy.

Connectivity and Extras: Wireless and Video Features

Canon’s SX40 HS supports Eye-Fi wireless cards, offering Wi-Fi enabled photo transfer - a handy feature when uploading on the go. Despite this, it lacks Bluetooth or NFC, limiting seamless connectivity with smartphones.

Fujifilm X-S1 lacks wireless connectivity altogether, which may affect workflow for image sharing speed-conscious users.

For video, both cameras record Full HD 1080p, but frame rates vary: Canon tops out at 24fps in 1080p, while Fujifilm can do 30fps. The X-S1 includes a microphone port, unlike the Canon, affording better audio options for videographers.

Neither camera supports 4K or high-frame-rate slow motion, so video is serviceable but not cutting edge by today's standards.

Comprehensive Performance Ratings: Summarizing the Battle

Quantitatively, the Fujifilm X-S1 pulls ahead in almost all performance metrics due to its larger sensor, superior autofocus, better lens sharpness, and higher resolution screen.

Canon SX40 HS remains competitive with its longer zoom range, lighter weight, articulated screen, and Eye-Fi compatibility that enhances wireless transfer.
