Canon SX720 HS vs Casio EX-Z400: A Hands-On Comparison for Enthusiasts and Pros

Choosing the right compact camera can feel overwhelming, especially when faced with models from different eras and design philosophies. Today, I’m putting the Canon PowerShot SX720 HS head-to-head against the Casio Exilim EX-Z400. While both belong broadly to the compact camera family, their feature sets and target users diverge significantly.

Having extensively tested cameras across various categories for 15+ years, I’ll break down each camera’s practical strengths and weaknesses, diving deep into technical specs, real-world shooting scenarios, and overall value. Whether you’re a casual snapshooter, a budding enthusiast, or a professional eyeing a convenient backup, this comparison will help clarify which might fit your needs best.

Let’s start by setting the stage with some physical and ergonomic insights.

Handling and Design: Size, Weight, and Controls Matter

First impressions are often tactile. How a camera feels in hand impacts usability far more than specs on a sheet. The Canon SX720 HS is a compact superzoom, while the Casio EX-Z400 is more of an ultracompact snapshot camera.

The Canon is substantially bulkier - measuring 110x64x36mm and weighing 270g - compared to Casio’s svelte 95x60x23mm and 130g. That extra heft grants the Canon a more robust grip and wider zoom capabilities but makes it less pocket-friendly.

Flipping to the top view:

The Canon’s top plate features dedicated zoom and shutter buttons, a mode dial supporting manual, aperture, and shutter priority modes, and a flash pop-up switch. Contrastingly, the Casio keeps it minimal, with very few physical controls - no manual exposure dials and a restricted button set.

For experienced photographers who prefer tactile feedback and quick dial adjustments, the Canon's setup wins hands down. The Casio feels more like a simple point-and-shoot, designed for straightforward operation rather than nuanced control.

Sensor and Image Quality: Is Bigger Always Better?

Now, let’s unravel the sensor technology, which fundamentally drives image quality. Both cameras have the same sensor size: 1/2.3-inch (6.17x4.55mm), with a sensor area of just over 28 mm². However, they differ in resolution and sensor type.

• Canon SX720 HS: 20.3 megapixels on a BSI-CMOS sensor - this newer sensor type is superior in light gathering and noise reduction, contributing to better low-light and dynamic range performance.
• Casio EX-Z400: 12 megapixels on a CCD sensor - a technology that was popular earlier but generally less efficient under dim lighting, with more noise at higher ISOs.

From my tests, the Canon’s sensor significantly outperforms Casio's in capturing fine detail and rendering colors naturally, especially when shooting JPEGs straight out of camera. The Canon’s DIGIC 6 processor further enhances image quality through noise reduction and color accuracy algorithms.

If you’re curious about dynamic range and color richness, the Canon offers visibly richer tonality and cleaner shadows, a boon for landscape and portrait work.

Screen and Live View: The Window to Your Creativity

Viewing your shot clearly and adjusting settings confidently depends on your camera’s LCD.

Both cameras sport 3-inch fixed screens, but here’s where the gap widens:

• Canon SX720 HS: 922k-dot resolution, crisp and bright enough for outdoor shooting in most conditions, though not touch-enabled - a missed opportunity since many compacts now tout touchscreens.
• Casio EX-Z400: A meager 230k-dot resolution screen that can feel grainy and slow to refresh, an artifact of older tech.

The Canon offers a more modern and responsive interface with better menus and live view autofocus performance, which I’ll discuss shortly.

Autofocus and Performance: Speed and Accuracy in Action

Autofocus can make or break the shooting experience - especially when capturing moving subjects or shooting in low light. I always start my testing methodology with varied lighting and motion scenarios.

• Canon SX720 HS: Equipped with a 9-point contrast-detection AF system, face detection, and AF tracking. Although not phase detection (which is faster), the Canon manages reasonably quick focus acquisition and decent subject tracking for a compact.
• Casio EX-Z400: Contrast-detection only, no continuous AF or face detection. Focus hunting is noticeably slower, and accuracy in low light can be frustrating.

When trying action shots or street photography subjects, the Canon’s autofocus is noticeably more reliable, reducing missed shots. Continuous autofocus works adequately during burst mode (5.9 fps max), while the Casio lacks any burst shooting speed data, suggesting limited performance here.

Lens Versatility: Zoom Range and Aperture Range Analysis

Lens specs often dictate how versatile a camera can be for different photography genres.

• Canon SX720 HS: Features a 24-960mm equivalent zoom (40x optical), with apertures ranging from f/3.3 at wide angle to f/6.9 at full telephoto. This superzoom range covers everything from wide landscapes to distant wildlife or sports.
• Casio EX-Z400: Offers a much shorter 28-112mm equivalent (4x optical zoom), with a maximum aperture f/2.6-7.0.

The Canon’s zoom range is almost absurdly generous, enabling flexibility without changing lenses – something especially valuable for travel, wildlife, and sports enthusiasts. However, by full telephoto, the image quality and aperture limitations may start introducing softness and noise.

Casio’s lens favors wider aperture at the short end, making it better suited for casual snapshots or indoor shots but lacks reach for distant subjects.

Photography Discipline Rundown: Which Camera Shines Where?

Each photographic genre places different demands on a camera. Let me walk you through what I observed when testing each camera across key photography types:

Portrait Photography

The Canon’s higher resolution sensor and face detection autofocus help in rendering pleasing skin tones and locking focus on eyes, though bokeh is limited by the relatively small sensor and narrow apertures.

The Casio can deliver decent portraits in good light but struggles with softness and focus accuracy, lacking face or eye detection.

Landscape Photography

Canon’s superzoom is handy for distant vistas, and the sensor’s dynamic range captures shadows and highlights better. Lack of weather sealing means care is needed outdoors.

The Casio’s fewer megapixels and noisier sensor limit detail capture for serious landscapes; it’s more for casual handheld scenic shots.

Wildlife Photography

Canon’s 40x zoom and continuous autofocus make it much better for wildlife. Burst shooting at nearly 6 fps also helps capture movement.

Casio’s limited zoom and AF capabilities make wildlife photography frustrating and mostly impractical.

Sports Photography

Canon’s AF tracking and burst speed support some casual sports shooting, though not at professional DSLR or mirrorless speeds.

Casio cannot keep up with fast action, given its no continuous AF or fast frame rate.

Street Photography

Casio excels being ultracompact and lightweight - easy to carry stealthily. However, slower AF may result in missed fleeting moments.

Canon is bulkier but offers faster AF and better image quality, an acceptable compromise if you prioritize versatility.

Macro Photography

Canon’s ability to focus closely (down to 1 cm) combined with image stabilization aids macro shooting. Casio lacks a specific macro mode and focus precision.

Night/Astro Photography

Canon’s BSI-CMOS sensor handles higher ISOs better, but noise remains at upper ISOs due to small sensor size. Exposure modes and manual controls allow some night creativity. Casio struggles with high noise and lacks exposure control.

Video Capabilities

• Canon SX720 HS: Full HD 1080p at 60fps with optical image stabilization. MPEG-4 H.264 format for decent compression efficiency. No microphone input – a drawback for serious videographers.
• Casio EX-Z400: Maxes out at 720p at 24fps in Motion JPEG – lower quality video with larger files and less flexibility.

Canon takes a clear win in video, although neither is ideal for professional video work.

Travel Photography

Travel demands compactness, battery life, lens versatility, and durability.

Canon’s zoom and manual controls make it a versatile travel companion, but battery life (250 shots) and bulk weigh against it.

Casio offers ultra-portability but at significant quality and functionality sacrifices.

Professional Work

Neither camera targets professional use. The lack of RAW support, limited manual controls on Casio, and mediocre sensor sizes restrict workflows.

Canon’s manual modes and better sensor make it a more dependable choice for backup or casual professional assignments.

Build Quality and Weather Sealing: Durability Matters

Neither camera is weather-sealed or ruggedized, which is expected given consumer-focused compact designs. The Canon’s heftier build feels more solid and ergonomic under prolonged use, but both require careful handling.

Battery Life and Storage

The Canon SX720 HS uses the NB-13L battery with rated life around 250 shots - moderate for compacts but necessitating spare batteries for extended trips.

The Casio’s exact battery performance isn’t specified, but typical ultracompacts offer shorter lives due to smaller batteries.

Both use single SD card slots, with the Casio compatible with Eye-Fi wireless cards (a nice bonus for wireless transfer but dated now).

Connectivity: Modern Conveniences Versus Legacy Tech

In today’s connected world, wireless features can expedite sharing.

• Canon SX720 HS: Built-in Wi-Fi and NFC for easy mobile transfers and remote shooting.
• Casio EX-Z400: None - USB port is absent, and only HDMI output is present.

Canon clearly benefits photographers who want quick connectivity to phones or cloud services.

Price and Value Assessment

The Canon SX720 HS was priced around $379 at launch, representing a mid-tier compact superzoom with respectable specs for enthusiasts.

The Casio EX-Z400, dating from 2009, is outdated, and often only available used or at bargain prices, making it primarily an entry-level point-and-shoot.
