Canon SX620 HS vs Casio EX-Z35: An Expert Comparison for Photography Enthusiasts

Choosing the right compact camera for your photography needs involves more than just scanning specs - it demands hands-on insights and real-world performance analysis. Having personally tested thousands of cameras over my 15+ years in photography equipment review, I’m here to guide you through a detailed head-to-head comparison of two very different but popular compact cameras: the Canon PowerShot SX620 HS and the Casio Exilim EX-Z35.

These cameras target entry-level users and casual shooters, yet they cater to distinct use cases. Below, I unpack their technical features, imaging capabilities, handling characteristics, and shooting performance across multiple genres - from portrait and landscape to travel and video. My goal is to help you understand which camera best fits your style, budget, and photographic ambitions.

A Tale of Two Generations: Specs in Context

Before diving into the nuances, it’s important to set the stage with an overview of each camera’s core specs.

This table shows that the Canon SX620 HS benefits from six more years of technological evolution, especially with its more advanced sensor and expanded zoom range. But specs don’t tell the full story. Let’s explore how these specifications translate into everyday photography and who will benefit most from each camera.

Physical Design: Handling and Ergonomics

When shooting, a camera’s physical feel can make or break your experience. Both the Canon SX620 HS and the Casio EX-Z35 are pocket-friendly, designed for portability and on-the-go shooting.

Size and ergonomics side-by-side

Canon SX620 HS
Weighing in at 182 grams and measuring roughly 97 x 57 x 28 mm, the SX620 HS is compact yet comfortable to hold thanks to a modest handgrip bump. The finish feels solid, and the build is typical Canon - functional with a focus on user-friendliness over ruggedness. The button layout makes one-handed operation fairly easy for most users.

Casio EX-Z35
Smaller and lighter at 124 grams and circa 99 x 57 x 20 mm, the EX-Z35 is ultra-slim and pocketable, even if your pockets are tight. Because of its ultracompact design, it lacks a grip, so holding steadily can require some practice, especially for prolonged shooting sessions. The minimalistic approach means fewer physical controls.

Which feels better in day-to-day use?

I found the Canon provides better ergonomics for longer shoots - you get a more secure hold and easy reach to key controls. The Casio’s slim profile is great for true pocket portability, but it can feel less natural to hold steady, particularly with the relatively long zoom on the Canon.

Design Language and Control Layout

User interface can significantly affect shooting flow, especially when you want to adjust settings quickly.

Top view: control placement and dials

The Canon SX620 HS impresses with a well-laid-out top plate - there is a modest zoom lever wrapped around the shutter button plus a mode dial on the back, although exposure modes are limited (no priority or manual). The Canon also incorporates a dedicated flash button and easy access to Wi-Fi functions.

The Casio EX-Z35 is extremely minimal. No dials or dedicated drive mode buttons; instead, settings are adjusted through menus accessed by a four-way pad and function buttons, common for ultracompact cameras of its era.

If you like quick access for exposure compensation, white balance, or ISO, the Canon SX620 HS gives you slightly more convenience. However, both cameras cater mostly to automatic and scene mode shooting rather than manual control enthusiasts.

Sensor and Image Quality: The Heart of the Matter

Image quality is crucial, and here the Canon holds a marked advantage.

Sensor comparison: size and resolution

Canon SX620 HS

• Sensor: 1/2.3” Backside Illuminated CMOS (BSI-CMOS)
• Resolution: 20 MP (5184 x 3888), no RAW support
• Advantages: BSI sensor technology improves low-light performance and dynamic range relative to CCDs.

Casio EX-Z35

• Sensor: 1/2.3" CCD
• Resolution: 12 MP (4000 x 3000), no RAW support
• CCDs generally excel in color rendition but offer lower noise performance at higher ISOs compared to modern CMOS sensors.

Real-world photographic impact

Having tested both cameras side-by-side, the Canon SX620 HS produces sharper, more detailed images with better color accuracy and less noise, particularly above ISO 400. The Canon’s BSI-CMOS sensor also rendered improved dynamic range, meaning recovered highlights and retained shadow detail were noticeably better in challenging light.

The Casio’s CCD sensor outputs softer images with a characteristic warmth to color but significantly visible noise beyond ISO 200. Dynamic range is limited, so it struggles more with contrast extremes. For casual snapshots in good lighting, the EX-Z35 can perform adequately, but it won’t stand up to the Canon’s better technical baseline.

Autofocus and Shooting Speed

Autofocus (AF) system responsiveness and accuracy affect your success rate, especially for fast-moving or spontaneous moments.

Canon SX620 HS

• 9 AF points with face detection
• Contrast-detection AF only (no phase detection)
• Offers continuous AF and tracking in live view

Casio EX-Z35

• Single contrast-detection autofocus
• No face detection or tracking
• Continuous AF not supported

I evaluated autofocus performance shooting moving subjects and faces under various light conditions. The Canon SX620 HS micro-adjusts focus reliably and locks quickly onto faces in decent light, an observation consistent with Canon’s general autofocus expertise.

The Casio is slow and less consistent. It often hunts or misses focus, especially in low light or when trying to capture moving subjects.

Burst and continuous shooting

• Canon: 2.5 fps continuous shooting
• Casio: Not supported or unspecified

Neither camera is designed for sports or wildlife bursts, but the Canon’s continuous mode offers more flexibility if you want to capture fleeting moments.

LCD Screen and User Interface Review

LCD screen quality impacts image review and composing shots in live view.

Back screens compared

The Canon SX620 sports a 3-inch fixed LCD with 922k-dot resolution, bright and with good color fidelity. Using it outdoors in sunlight, I found its visibility decent, though it could benefit from anti-reflective coatings.

The Casio’s 2.5-inch 230k-dot screen is noticeably dim and coarse in resolution, making it harder to evaluate focus and exposure precisely. For framing and playback, the Canon’s screen provides a significant advantage in usability.

Lens and Zoom Capabilities: Range Meets Versatility

The Canon SX620 HS features an impressive 25x optical zoom covering a 25-625 mm equivalent focal range, perfect from wide-angle landscapes to distant wildlife or sports details. Aperture narrows from f/3.2 to f/6.6, which is typical for superzooms.

The Casio offers a modest 3x zoom at 36-107 mm equivalent, f/3.1-5.6 – more limiting but arguably sufficient for casual snapshots, portraits, and short telephoto framing.

From practical experience, the Canon’s lens versatility is extraordinary in its class, allowing you to experiment across genres without changing lenses - no easy feat for point-and-shoot cameras.

Stability and Flash Performance

Image stabilization is key to sharpness at telephoto or low shutter speeds.

• Canon SX620 HS: Optical image stabilization (OIS)
• Casio EX-Z35: None

Canon’s OIS lead to sharper photos handheld, especially at longer focal lengths and indoors. The Casio’s lack of stabilization means you may need a tripod more often for sharp results.

Flash range is modest on both, with Canon reaching around 4 meters and the Casio about 3.2 meters. Both offer common flash modes, but none support external flash units.

Video Recording Capabilities

Video continues to be an important feature for many users.

The Canon’s Full HD video and optical stabilization make it clearly superior for casual video shooting. The Casio’s video resolution is dated by modern standards and lacks steadying features, limiting its value if you care about video quality.

Connectivity and Storage

Connectivity can streamline image sharing and workflow.

• Canon SX620 HS: Built-in Wi-Fi and NFC for fast wireless transfer to smartphones or computers. Also includes HDMI and USB 2.0 ports.
• Casio EX-Z35: No wireless capability. USB 2.0 only. No HDMI.

Wireless on the Canon means less hassle when transferring images, a strong selling point for casual social or travel photographers.

Both cameras accept SD/SDHC/SDXC cards and have one card slot.

Battery Life and Power Considerations

Battery endurance affects how long you can shoot without interruption.

• Canon SX620 HS: Rated for ~295 shots per charge using a proprietary Battery Pack.
• Casio EX-Z35: Battery life info unavailable from official specs; uses NP-82 battery.

From experience, the Canon’s battery comfortably lasts a day of moderate shooting, but you may want a spare for extended travel shoots. The Casio’s performance is less provable due to the camera’s age but expect shorter life given its compact size and CCD sensor power draw.

Durability and Weather Resistance

Neither camera offers weather sealing or rugged features. If you need a camera that stands up to harsh conditions, look elsewhere.
