Compact Cameras Head-to-Head: Canon PowerShot SX240 HS vs Casio Exilim EX-S5

When stepping into the world of compact cameras, photographers often seek a balance of portability, image quality, user-friendly controls, and versatility. Today, I’m diving deep into a direct comparison between two intriguing compacts: the Canon PowerShot SX240 HS, a small sensor superzoom, and the Casio Exilim EX-S5, an ultraportable ultracompact. From my years testing hundreds of such models, I’ll share hands-on insights with technical analysis and real-world performance to help you decide which one best fits your photographic lifestyle.

First Impressions and Physical Handling

Experienced photographers often say ergonomics shape the entire shooting experience. The Canon SX240 HS feels like a compact with serious intentions. It’s got a sturdy, well-gripped body that fits nicely in the hand. In contrast, the Casio EX-S5 is notably smaller and lighter, with a sleek, ultrathin design that easily slips into a pocket but sacrifices some operational comfort.

A side-by-side physical comparison tells a strong story about their different approaches:

The Canon SX240 HS measures 106 × 61 × 33 mm and weighs 224 grams. This is a manageable size for day-to-day shooting with some grip security, but not bulky enough to feel cumbersome. The Casio EX-S5 is significantly slimmer at 102 × 35 × 22 mm and only 100 grams – truly pocket-friendly.

In my testing, the Canon’s ergonomics greatly favor extended handheld shooting sessions, while the Casio’s slimness comes with limited physical controls and a more delicate grip. For street photography or travelers wanting minimal kit, the EX-S5’s unobtrusive form is appealing. However, you won’t get the tactile feedback or the sense of command that the Canon provides.

Control Layout and User Interface

Having rapid access to essential controls is key when capturing fleeting moments. Let’s compare the control schemes by looking at the cameras’ top views.

The Canon SX240 HS offers dedicated buttons for exposure modes (Manual, Aperture Priority, Shutter Priority), a zoom rocker, and a clearly labeled mode dial. It even includes a custom function button and exposure compensation dial. The interface feels thoughtfully designed for enthusiasts who want to fine-tune settings swiftly.

The Casio EX-S5 is much more minimalistic, with fewer physical buttons and no dedicated dials for manual exposure modes. It’s designed for simplicity and auto modes rather than hands-on control. This reflects the EX-S5’s “point-and-shoot” ethos, geared toward casual shooters wanting ease over depth.

In my experience, while beginners may appreciate the Casio’s streamlined layout, serious photographers will miss the hands-on control finesse of the Canon – particularly when chasing fast action or experimenting with creative exposure settings.

Sensor Technology and Image Quality Fundamentals

Both cameras share a common sensor size of 1/2.3-inch (measuring 6.17 x 4.55 mm and approximately 28.07 mm²), but the underlying sensor technologies differ materially, impacting dynamic range, noise performance, and overall image quality.

Canon SX240 HS Sensor:

• Type: Back-illuminated CMOS (BSI-CMOS) sensor
• Resolution: 12 megapixels (4000 x 3000)
• Max ISO: 3200 native
• Anti-aliasing filter present

The Digic 5 processor combined with the BSI-CMOS sensor brings respectable dynamic range for this class. Back-illuminated design essentially improves low-light performance by gathering light more efficiently, resulting in cleaner images at higher ISOs and better shadow detail.

Casio EX-S5 Sensor:

• Type: CCD sensor
• Resolution: 9 megapixels (3648 x 2736)
• Max ISO: 1600 native
• Anti-aliasing filter present

CCD sensors historically produce excellent color rendition and low noise at base ISOs, but their max ISO capacity and dynamic range lag behind modern BSI-CMOS sensors. The Casio’s max ISO of 1600 and older processing result in more noise and less shadow recovery.

In practical shooting across different lighting scenarios, I find the Canon SX240 HS delivers sharper images with higher resolving power and improved noise control at ISO 1600 and above. The Casio’s images are respectable for well-lit scenes but show softness and noise creeping in under challenging conditions.

LCD Screens and Framing Experience

A camera’s rear LCD screen is an essential interface for composing shots and reviewing images. Let’s examine how these two models stack up.

The Canon SX240 HS sports a 3-inch Fixed PureColor II TFT LCD with 461k dots resolution. This screen offers crisp, bright, and accurate color representation, which aids in precise manual focusing and image assessment in daylight.

By contrast, the Casio EX-S5 has a smaller 2.7-inch screen with only 115k dots resolution. This lower pixel density results in a grainier, less sharp preview that can make critical review and menu navigation more difficult in bright environments.

I noticed that the enhanced screen quality on the Canon significantly improves the user experience, especially when dialing in manual focus or confirming exposure. The Exilim’s screen is more for snapshots and casual viewing.

Autofocus Systems and Shooting Speed

Autofocus capability is a make-or-break criterion for photographers shooting moving subjects or spontaneous moments.

The Canon SX240 HS is equipped with a 9-point contrast-detection AF system, including face detection and continuous AF modes. Although not on par with modern phase detection systems, it performs well for a compact, locking focus with reasonable speed and accuracy.

The Casio EX-S5 uses a simpler contrast-detection system without face detection or continuous AF options. It lacks an autofocus tracking system and offers a more basic single AF point.

In burst shooting, Canon records up to 2 fps, while Casio’s specs don’t indicate a continuous burst mode, meaning you’re limited to single exposures. Speed-sensitive genres like sports or wildlife will find the SX240’s AF and shooting rates more credible.

Lens Capabilities and Versatility

The Canon SX240 HS shines with an impressive 20x optical zoom covering a 25-500mm equivalent focal range with a maximum aperture of f/3.5-6.8. This versatility empowers photographers to handle a remarkable array of scenarios - from wide landscape shots to distant wildlife or sports action.

The Casio EX-S5’s focal length details are unspecified here, but being an ultracompact, it features a shorter zoom range with a max aperture of f/3.1-5.6, typically translating to less telephoto reach and a more limited creative toolkit.

In real-world shooting, Canon’s extensive zoom flexibility and image stabilization make it a strong contender for travel and general-purpose photography, where you can’t carry multiple lenses. Meanwhile, Casio’s lens setup suits street, candid, and casual shooting where sharpness is prioritized over reach.

Image Stabilization and its Impact

I always emphasize the value of optical image stabilization (OIS) in compact cameras to combat shake, especially at long focal lengths or low shutter speeds.

The Canon SX240 HS includes optical image stabilization which effectively reduces blur from hand movement - a crucial advantage given its 20x zoom lens. This feature consistently yields sharper images in dim light or when using telephoto.

The Casio EX-S5 lacks any form of image stabilization. I found this is a limiting factor for low light and zoomed shooting, as camera shake becomes more apparent, resulting in reduced image sharpness.

For casual snapshots, this might be acceptable, but photographers seeking versatility and image clarity will appreciate Canon’s OIS.

Video Recording Performance

Video remains a critical component for many photographers, blending still capture with moving images.

Canon SX240 HS:

• Maximum video resolution: Full HD 1920 x 1080 at 24 fps
• Additional resolutions: 1280x720@30fps, slow-motion VGA and QVGA modes
• Codec: H.264
• No external mic port or headphone jack

Casio EX-S5:

• Maximum video resolution: 848 x 480 at 30 fps (Motion JPEG)
• Lower resolution 640x480 and 320x240 also supported
• No audio input/output ports

While neither camera is designed primarily for videography, the Canon’s full HD video capability offers superior resolution and compression efficiency, translating to cleaner video files with more detail. Its lack of external audio connections, however, restricts professional use.

Casio’s video options remain basic and low resolution, suited only for casual video clips or memories.

Battery Life and Storage

Endurance in real-world shoots is non-negotiable. Canon’s NB-6L battery delivers approximately 230 shots per charge under standard testing, while Casio’s battery life specifications are less clear but known to be lower due to the small form factor and lack of stabilization.

In practice, the Canon’s battery performance allows a full day of casual shooting with moderate video, whereas the Casio may require carrying a spare battery for a full-day outing.

Both cameras accept SD/SDHC cards for storage. The Casio is notable for compatibility with Eye-Fi wireless SD cards, adding a degree of wireless image transfer - a surprisingly forward feature for a camera from its generation.

Build Quality and Environmental Resistance

Neither camera is weather-sealed or ruggedized. The Canon SX240 HS has a sturdy plastic body with a matte finish to better resist fingerprints and minor knocks. The Casio EX-S5’s ultrathin design is more fragile and better suited for gentle use indoors or in fair weather.

Pro photographers needing reliability in challenging environments should look elsewhere but will find the Canon’s build reassuring for most everyday scenarios.

Sample Image Quality Comparison

A picture is worth a thousand words, and I invite you to scrutinize real-world images taken with both cameras under similar conditions.
