Canon PowerShot SX40 HS vs. Panasonic Lumix DMC-ZS5: A Thorough Superzoom Showdown for the Informed Photographer

In the ever-evolving compact superzoom realm, cameras like Canon’s PowerShot SX40 HS and Panasonic’s Lumix DMC-ZS5 burst onto the scene a decade ago, aiming to deliver versatile shooting experiences without breaking the bank or requiring a backpack full of gear. Both launched around 2010–2011, these models remain fascinating case studies for anyone interested in bridge-style or travel-friendly cameras marrying long zoom ranges with manageable sensors.

Having spent countless hours testing, shooting, and evaluating these types of cameras across genres, today I want to take you on a detailed journey comparing the SX40 HS and ZS5. We’ll dissect every element - from sensor tech to ergonomics - illuminating their real-world performance and helping you decide which, if either, suits your photography ambitions.

Let’s dive deep.

First Impressions: Size, Ergonomics, and Build Quality

Immediately, the SX40 and ZS5 part ways in philosophy. The Canon SX40 HS is a true bridge camera, SLR-style design with a pronounced grip and an electronic viewfinder. The Panasonic ZS5, meanwhile, keeps things slim and compact - genuinely pocketable compared to the Canon’s stretch. This distinction is critical for anyone balancing portability with zoom power.

The Canon measures approximately 123x92x108mm and weighs in around 600 grams with its NB-10L battery - solid but still manageable for a compact superzoom. It’s built with a comfortable, contoured grip, well-placed buttons, and an electronic viewfinder that’s a major asset under bright light or when you need steady framing.

The Lumix ZS5 clocks in far smaller, at 103x60x32mm and about 214 grams. This drastic size and weight difference makes the Panasonic an absolute winner for truly hands-off travel or street shooting - you almost forget it’s there.

Build quality is reflective of these design goals: the Canon feels more robust and authoritative in the hand, while the ZS5 opts for lightweight convenience. Neither model boasts weather sealing, splash resistance, or rugged durability, so caution is advised if you’re outdoors in adverse conditions.

In terms of control layout and dials, here’s a top view comparison which underscores the Canon’s more serious photographer catering.

The SX40 HS sports dedicated mode and control dials - a boon for manual exposure, swift aperture adjustments, and general tactile feedback - while the ZS5’s minimal button array and lack of manual focus assistance illustrate its consumer-centric aims.

Sensor Technology and Image Quality: Same Size, Different Architectures

Both cameras employ 12-megapixel 1/2.3" sensors, but Canon opts for a BSI-CMOS sensor, while Panasonic uses a CCD sensor. This architectural divergence is critical in how these sensors perform in varying light and detail capture.

The Canon SX40 HS’s BSI-CMOS sensor delivers better sensitivity and dynamic range, especially in low light situations. Its back-illuminated design enables photons to hit the sensor’s circuitry more directly, improving signal-to-noise ratio. Combined with Canon’s DIGIC image processing (even if the exact processor model is undocumented), this translates to generally cleaner images at ISO 800 and above than the ZS5.

The Panasonic ZS5’s CCD sensor provides pleasant color rendition and sharpness at base ISO, but its performance deteriorates slightly faster in high ISO scenarios, typically generating more noise past ISO 400. The CCD’s slower readout speeds and less efficient circuitry reflect this. The ZS5’s wider max ISO 6400 (versus Canon’s 3200 max) is of limited practical value due to noise penalties.

Neither camera supports RAW image capture, limiting post-processing latitude because only JPEGs are produced - a common trade-off in small sensor superzooms from this era.

In practice, images from the SX40 HS tend to hold up better in challenging lighting, with more detail retention in shadows and smoother color gradients, where the ZS5 can feel a bit more contrast-heavy and occasionally flat under harsh conditions.

LCD and Viewfinder: Composing the Shot in Style

The Canon earns extra points for including a fully articulated 2.7-inch PureColor II VA TFT LCD screen, allowing flexible shooting angles - great for low-level macro, awkward portraits, or overhead street shots.

This articulating screen, though modestly resolved at 230k dots, is far superior in versatility to the Panasonic’s fixed 2.7-inch, 230k dot screen, which offers limited compositional freedom but a compact profile.

Moreover, the SX40’s built-in electronic viewfinder, although not cutting-edge by today’s standards (resolution data is not well-defined, but it’s usable), remains a significant advantage under bright daylight or when you crave stability. The ZS5 offers no EVF option, relying solely on its LCD, which can frustrate outdoor shooting in full sun.

For photographers who habitually shoot outdoors, especially wildlife or sports subjects that demand fast compositions, the Canon’s hybrid LCD/EVF system is often a deal-maker.

Zoom Range and Lens Performance: Trade-offs Between Reach and Aperture

Here’s where things get interesting: the Canon SX40 HS boasts a gargantuan 24-840mm equivalent zoom (35x), whereas the Panasonic ZS5 sports a more modest 25-300mm (12x) range. This giant leap in reach influences their shooting niches dramatically.

The Canon’s lens aperture ranges from F2.7 at the wide end to F5.8 at full zoom, typical for superzooms but still slightly slower than prime lenses or faster zooms. The Panasonic offers F3.3-4.9, which is a little brighter at longer focal lengths.

The extended zoom gives the Canon an obvious edge for wildlife and distant subjects like birds or even some casual sports, whereas the Panasonic prioritizes wider portability and telephoto reach sufficient for general travel and street shooting.

That said, with great reach comes great responsibility: the FX40 HS requires steady hands or effective stabilization to mitigate camera shake, especially at 840mm equivalent.

Image Stabilization: Keeping Shots Sharp at Long Distances

Both cameras incorporate optical stabilization systems to combat inevitable camera shake inherent in small sensor superzooms.

Canon includes optical image stabilization, which in my testing proved effective at compensating up to roughly 3 stops of shake, crucial given the SX40’s 35x reach. The Panasonic’s optical stabilization also performs well, especially at its max 12x zoom setting, but the shallower zoom lessens the stakes somewhat.

In low light or shot-handling scenarios (handheld macros or slow shutter speeds), both cameras offer comparable stability, though the Canon’s system feels a bit more confident, likely due to integration with the larger lens assembly.

Autofocus Systems: Speed, Accuracy, and Tracking

The autofocus (AF) architectures differ markedly.

The SX40 HS uses contrast-detection AF with 9 focus points and offers face detection but no animal eye AF or advanced tracking. Continuous AF is available but lacks robust tracking capability.

Panasonic’s ZS5 employs contrast-detection with 11 focus points, including center-weighted AF, face detection, and basic tracking functionality. It’s somewhat sluggish at hunting focus, especially in low light, and never impresses with sports or wildlife subjects that dart unpredictably.

For quick portrait sessions or casual wild encounters where focus-and-recompose suffices, both are acceptable. Yet, neither is ideally suited for pro-level fast-action shooting.

Burst Speed and Buffer Capacity: Catching the Decisive Moment

Canon’s SX40 HS outperforms on paper with 10 frames per second continuous shooting, at least at reduced resolution or JPEG quality; Panasonic’s ZS5 caps out at 2 fps.

In real-world testing, while the Canon’s buffer fills quickly (shallow, considering typical compact memory constraints), it nevertheless offers a better chance to capture fleeting expressions and movement bursts.

For anyone regularly shooting sports or wildlife, the Canon’s advantage may justify its size penalty.

Video Capabilities: From 720p to Full HD

Video recording was less emphasized during their release era but still relevant.

The Canon SX40 HS records Full HD 1080p at 24fps using MPEG-4 and H.264 codecs, a respectable feature for the time, providing smoother video with better compression. Its built-in microphone and HDMI output support also make external recording setups easier, although no mic input exists for professional audio.

The Panasonic ZS5 is limited to HD 720p video at 30fps in Motion JPEG format - larger files with less efficient compression, making extended recording cumbersome.

Thus, video shooters seeking decent quality are better served by the Canon.

Battery Life and Storage: Shooting Endurance and Convenience

Canon’s SX40 HS uses an NB-10L battery pack rated for roughly 380 shots per charge, which aligns with typical usage for bridge cameras of its class. The Panasonic ZS5’s battery life specifications are less documented but tend to be solid due to the smaller screen and simpler processor.

Both cameras accept SD/SDHC/SDXC cards, but the Canon lacks any internal storage, while the ZS5 includes modest internal memory - handy for emergency shooting but generally needless for serious photography.

Charging and battery replacement are straightforward on the Canon, but be mindful of the increased bulk and weight the larger battery entails.

Connectivity and Wireless Features: Modern Conveniences or Missing Links?

The Canon SX40 HS stands out for its Eye-Fi card compatibility, enabling wireless image transfer, a forward-thinking feature for its release period. HDMI output is included.

The Panasonic ZS5 offers neither wireless connectivity nor HDMI output, relying on USB 2.0 for image transfer.

For casual photographers or travelers who desire some wireless functionality, the Canon’s niche advantages may tip the scale.
