The SX620 HS measures approximately 97 x 57 x 28 mm and weighs 182 grams, whereas the Casio EX-H15 is slightly larger at 101 x 60 x 28 mm but lighter at 161 grams. Neither offers overt ruggedness or weather sealing - something to consider if you shoot outdoors frequently.

The Canon maintains a smooth matte finish with a moderate grip area, which contributes to better handling, especially when shooting at long zoom ranges. The Casio, while slimmer, has a more plasticky feel and minimal grip robustness. I found that for extended shooting sessions, Canon’s ergonomics provide more confidence and stability. Both lack viewfinders, relying solely on rear LCDs.

Controls on the Canon SX620 HS emphasize simplicity, with clear mode dials and dedicated zoom levers around the shutter button. The Casio’s control scheme feels more basic and less tactile, which slowed me down when adjusting settings quickly in the field.

Ergonomics takeaway: Canon’s SX620 HS offers better grip, easier handling, and smarter button placement compared to Casio’s EX-H15, making sustained shooting more comfortable and intuitive.

Sensor and Image Quality: Battle of the 1/2.3” Sensors

Under the hood, both cameras share the same sensor size - a 1/2.3-inch type measuring 6.17 x 4.55 mm with a sensor area of roughly 28 mm². However, the Canon SX620 HS sports a 20-megapixel BSI-CMOS sensor coupled with Canon’s DIGIC 4+ processor, while the Casio EX-H15 uses a 14-megapixel CCD sensor.

BSI (Backside Illuminated) CMOS sensors like Canon’s are more efficient at capturing light, translating to improved low-light performance and dynamic range. In contrast, Casio’s CCD sensor, while capable of rich colors, typically struggles with noise at higher ISOs and limited dynamic range.

Real-world performance highlights:

• Resolution and Detail: Canon’s 20MP sensor delivers noticeably finer detail compared to Casio’s 14MP output. In tests, I zoomed into architectural shots and landscapes and found more sharpness retention with Canon.

• High ISO and Noise Handling: At ISO 800–1600, Canon begins to show noise but keeps it acceptable for web and print use. Casio’s images are noisier at ISO 400, reinforcing its suitability primarily for well-lit scenarios.

• Dynamic Range: Canon’s sensor reveals more shadow detail and highlight recovery, beneficial for outdoor photography with tricky lighting conditions.

• Color Rendition: Casio’s CCD occasionally produces oversaturated colors, which might appeal for casual snapshots but lacks the natural skin tones and subtle gradients that Canon’s system achieves.

Image quality takeaway: Canon SX620 HS’s 20MP BSI-CMOS sensor clearly outperforms Casio’s older CCD, particularly in resolution, ISO handling, and dynamic range - hallmarks vital for versatile shooting.

Autofocus and Shooting Responsiveness: Speed and Accuracy in Practice

Autofocus speed and accuracy can make or break a camera’s usability in real-world shooting scenarios. Canon equips the SX620 HS with 9 contrast-detection AF points, including face detection and tracking functions. The Casio EX-H15, in comparison, offers only single-area contrast-detection AF without face detection or tracking.

I tested both cameras under various conditions:

• Portraits with moving subjects: Canon’s face detection locks swiftly and maintains focus during gentle movement, while Casio struggles to acquire focus quickly and often hunts, missing decisive moments.

• Macro close-ups: Canon’s capability to focus down to 1 cm with its lens benefits close-up photographers, while Casio lacks detailed macro specs, reducing flexibility here.

• Burst and continuous shooting: Canon supports a 2.5 fps burst rate, a modest speed adequate for casual action but falling behind dedicated enthusiast cameras. Casio doesn’t specify continuous shooting performance, indicating limited burst capability.

Focus system takeaway: Canon SX620 HS offers a more modern, reliable autofocus system better suited for portraits, semi-action, and macro photography. Casio’s AF is simpler and less dependable for dynamic or detailed shooting.

Zoom and Lens Coverage: Versatility for Travel and Everyday Use

Both cameras feature fixed lenses with substantial zoom ranges:

• Canon SX620 HS: 25-625 mm equivalent (25× zoom), aperture F3.2-6.6
• Casio EX-H15: 24-240 mm equivalent (10× zoom), aperture F3.2-5.7

Canon’s longer telephoto reach gives it clear advantages for travel, wildlife, and candid street photography. However, its maximum aperture narrows significantly at the long end, limiting low-light telephoto use and precise background blur.

The Casio’s shorter zoom range offers slightly wider maximum aperture on the telephoto side, beneficial in daylight but falls short of Canon’s versatility for distant subjects.

Zoom lens takeaway: Canon’s extensive 25× zoom dominates for reach and framing flexibility. Casio is better sized for normal zoom ranges but less equipped for long-range shooting.

Screen and User Interface: Composing and Reviewing Your Shots

Each camera has a 3-inch fixed rear LCD, but with contrasting resolutions:

• Canon SX620 HS: 922k-dot resolution
• Casio EX-H15: 461k-dot resolution

Canon’s higher-res screen proves brighter, crisper, and easier to use outdoors or under varied lighting. The interface, while not touchscreen, provides straightforward menu navigation with clearly labeled buttons. Casio’s interface feels dated; the display appears less sharp and colors less vibrant.

Both cameras lack electronic viewfinders, possibly disappointing photographers accustomed to composing through a stable eyepiece.

Screen and UI takeaway: Canon offers a more pleasant and functional viewing experience, enhancing user confidence for framing and reviewing images.

Video Capabilities: Recording Quality for Casual Content Creators

Neither camera is designed with advanced video features, but they cover basic HD video:

• Canon SX620 HS records Full HD (1920×1080) at 30 fps with H.264 codec.
• Casio EX-H15 maxes out at HD (1280×720) at 30 fps, using Motion JPEG format.

Canon’s video files benefit from better compression efficiency, resulting in higher quality and smaller file sizes. Casio’s Motion JPEG tends to create larger files with less color depth.

Both lack microphone and headphone ports, meaning audio control is minimal for either. Optical image stabilization (Canon) vs sensor-shift stabilization (Casio) affects video smoothness, with Canon’s lens-based system yielding steadier handheld footage in my testing.

Video takeaway: Canon SX620 HS outperforms Casio EX-H15 in video resolution, compression efficiency, and stabilization support, making it the preferred choice for casual videographers.
