Casio EX-Z2000 vs Samsung SL620: A Hands-On Ultra-Compact Camera Showdown

In the ultracompact camera realm, choices often boil down to subtle details - minute sensor differences, lens attributes, ergonomics - that cumulatively impact your shooting experience. Today, I put two intriguing contenders head-to-head: the Casio EX-Z2000, announced early 2010, and Samsung’s earlier released SL620 (Pl65). Both belong to a breed of pocket-friendly digital cameras promising convenience without overwhelming complexity. However, among seasoned enthusiasts or even casual advanced shooters, how do these two machines measure up?

I’ve spent extensive hours testing, comparing, and dissecting every angle of these cameras - from sensor efficiency and lens sharpness to handling nuances and real-world shooting performance - to provide you with an authoritative appraisal founded on hands-on experience, technical expertise, and practical insights.

Let’s dive into their merits by evaluating the key factors that truly matter across diverse photography applications, while peppering in honest assessments, image samples, and final recommendations.

Pocket-Friendly Form Factor: Size and Ergonomics Matter More Than You Think

Ultracompact cameras are all about squeezing everyday versatility into a small envelope that won’t weigh you down or obstruct your casual shooting style. But even subtle differences in size, weight, and button layout can hugely affect in-the-moment usability.

Starting with dimensions, the Casio Exilim EX-Z2000 sports a slimmer and lighter profile, measuring only 99x58x17mm and weighing 152 grams. The Samsung SL620, though comparable in footprint, adds a little bulk at 92x61x23mm and tips the scales at 168 grams. That extra thickness and weight reflect in handling - particularly when shooting one-handed or slipping the camera into tight pockets.

Following ergonomics, the EX-Z2000’s sleek, flat design can feel somewhat minimalist - albeit responsive in everyday use - while the SL620’s slightly chunkier grip, with more pronounced contours, offers tangible security, especially for users with larger hands. This is important when shooting steadily without a tripod.

Another ergonomic aspect to highlight is the button layout and control access, which I’ll discuss fully with the camera interfaces below. But suffice to say, both cameras aim for simplicity over complexity, suitable mainly for straightforward point-and-shoot operations.

Design and Control Topography: How Intuitively Can You Shoot?

Beyond form, the tactile feel and control arrangement often dictate if you’ll enjoy (or endure) long shooting sessions. Here’s a direct side-by-side look at the top-deck design of these cameras.

The Casio EX-Z2000 keeps things sparse, with a compact shutter release and zoom toggle, but limited dedicated physical controls. It lacks manual exposure modes entirely, reflecting a pure consumer-grade approach. Its small screen and no viewfinder mean you'll always be composing and reviewing with LCD alone.

Samsung’s SL620 features a similar minimal control cluster but adds a function button that accesses some quick settings. Like the Casio, it lacks advanced manual controls and has no viewfinder, but the button travel feels a touch more tactile.

In practice, my experience showed neither camera will please photographers accustomed to manual aperture or shutter priority modes - both deliberately limit complexity, favoring quick point-and-shoot usability. That said, Samsung’s addition of face detection autofocus (which Casio lacks) can marginally improve selectivity in complex scenes and justify the marginally more complex UI.

Sensor Specifications and Image Quality: The Heart of the Camera Battle

When evaluating cameras, I start with the sensor - after all, it largely dictates image quality, dynamic range, noise performance, and color depth. Both the EX-Z2000 and SL620 rely on 1/2.3-inch CCD sensors, common in compact cameras of their era. Let’s break down their nuances.

• Casio Exilim EX-Z2000: 14MP resolution at 4320x3240 pixels, ISO 64–3200, sensor size 6.17x4.55 mm (total area 28.07 mm²)
• Samsung SL620: 12MP resolution at 4000x3000 pixels, ISO 80–1600, sensor size 6.08x4.56 mm (area 27.72 mm²)

The EX-Z2000 offers a modest bump in resolution and maximum ISO sensitivity, which might sound like a straightforward advantage. However, an increased megapixel count on the same sensor size implicates smaller pixel pitch, potentially affecting noise and low-light performance negatively unless supported by stronger image processing.

On the other hand, the SL620’s lower megapixel count and ISO ceiling suggest it might offer cleaner images at base sensitivities, which became evident in my side-by-side low-light testing - Samsung produced marginally smoother images with less chroma noise and better retention of shadow detail.

Neither camera delivers raw file support, which limits post-processing flexibility. Both utilize JPEG compression exclusively - something to consider for professionals or enthusiasts aiming for maximum image control.

In daylight and controlled studio conditions, resolution and color rendition were comparable. However, neither camera impresses seriously in dynamic range; both struggled with harsh highlights and deep shadows, a limitation predictable for their sensor class.

The Rear LCD Screen and User Interface: Framing and Reviewing Made Simple

An often-overlooked aspect in ultracompacts is the rear display, arguably your primary tool for composition and menu navigation.

The Casio EX-Z2000 offers a 3-inch fixed LCD with 461k-dot resolution - a strong point in its favor - delivering bright, sharp previews and facilitating easier manual framing.

Contrastingly, the Samsung SL620 has a slightly smaller 2.7-inch LCD at 230k-dot resolution, meaning images and menus appear less crisp, and interface navigation can feel cramped or grainier, especially outdoors under harsh light.

Neither has touchscreen functionality or an electronic viewfinder, so you’re perpetually dependent on the rear screen under all lighting conditions. Both provide live view autofocus, though the Casio’s faster refresh and more detailed feedback foster a smoother shooting flow.

Lens Characteristics and Autofocus: Zooming into the Details

Next up: lenses. Given both cameras have fixed zoom lenses (no interchangeable possibilities), their optical qualities are pivotal.

Focal range:

• EX-Z2000: 26-130mm equivalent (5x zoom), aperture f/2.8-6.5
• SL620: 35-175mm equivalent (5x zoom), aperture f/2.8-5.7

Casio’s wider starting focal length (26mm) is advantageous for landscapes and interiors. Meanwhile, Samsung’s telephoto reach to 175mm enables tighter framing at a distance, potentially better for casual wildlife or sports shooting.

Regarding maxima aperture, Samsung’s lens maintains a slightly brighter maximum aperture at telephoto (f/5.7 vs. f/6.5), helping in low light but marginally.

A notable difference is the EX-Z2000’s built-in sensor-shift image stabilization versus Samsung’s lack thereof. This stabilization presents tangible benefits when shooting handheld at telephoto or in dimmer lighting, visibly reducing motion blur.

Autofocus systems further tell a tale: Casio relies on contrast detection only without face detection, whereas Samsung combines contrast detection and face detection autofocus. The result? Faster, more reliable focusing on faces with the SL620, though both systems lag if there’s low contrast or fast movement.

Neither camera supports continuous AF or burst autofocus, so tracking moving subjects - important for wildlife or sports - is limited and often requires pre-focusing.

Real-World Photography Tests: How Do They Perform Across Genres?

To understand how these specs translate to daily shooting scenarios, I tested both cameras across key photography genres - because theoretical specs only get you so far without practical insights.

Portrait Photography

Skin tones require accurate color reproduction, gentle bokeh, and reliable eye detection to impress.

Neither camera supports eye detection AF or manual aperture control, limiting artistic depth-of-field effects. The EX-Z2000’s wider f/2.8 aperture at wide-angle helps slightly with background separation when shooting close up. However, bokeh is generally hard and busy, given small sensor sizes.

The Samsung’s face detection autofocus often performed more consistently for identifying and focusing on faces, a plus for casual portraiture.

Landscape Photography

Landscape demands resolution, dynamic range, and wide focal coverage.

Casio’s higher pixel count slightly improves detail rendition on rich landscapes but does not offset restricted dynamic range or lens softness at wide-angle edges.

The EX-Z2000 also benefits from its 26mm wide-angle focal length, capturing more expansive vistas compared to the SL620’s 35mm limit.

Neither camera is weather sealed, limiting harsh environment use.

Wildlife and Sports Photography

Here’s where burst rate, autofocus tracking, maximum zoom, and stabilization matter most.

Both cameras lack high burst rates or continuous AF, stunting their effectiveness for action shots.

The SL620’s 175mm lens gives a modest telephoto advantage, though image stabilization absent.

Overall, these cameras are not ideal for dedicated wildlife or sports photography but can manage casual distant shots in good light.

Street Photography

Stealth, quick handling, and low-light ability define a great street camera.

The EX-Z2000’s smaller size and lighter weight edge out the SL620 here, enabling less conspicuous shooting.

Snap autofocus and the brighter wide-angle lens aperture further support street shooting.

Macro and Close-Up

Samsung offers a 5cm macro focusing distance, enabling tighter close-ups than the Casio, which lacks macro specs.

Few other controls or focusing aids impact macro potential, but Samsung wins on versatility.

Night and Astro Photography

High ISO performance here is critical.

The EX-Z2000’s higher max ISO (3200) doesn’t translate to usable high-ISO shots - noise dominates from ISO 800 upwards.

Samsung’s more conservative max ISO fares slightly better with less noise in my test shots.

Neither offers manual bulb exposure or specialized astro modes.

Video Capabilities: Limited but Serviceable for Casual Use

Both cameras shoot video purely in Motion JPEG format with sub-HD limits.

• EX-Z2000: Up to 1280x720 at 30 fps
• SL620: Max 640x480 at 30 fps, with slow-motion modes (up to 60 fps at reduced resolution)

Neither offers 4K, microphone inputs, or advanced video controls.

Casio’s HD resolution video is an obvious upgrade but with compromised codec efficiency and limited audio capability.

Neither camera stabilizes video, further diminishing smoothness.

Battery Life and Storage: Practical Considerations

Both use removable rechargeable lithium-ion batteries:

• Casio uses NP-110 battery; Samsung uses a proprietary cell without a specified model, limiting swap possibilities.

Battery life data isn’t readily available from manufacturers, but real-world shooting indicates roughly 200 shots per charge for each, typical for favoring portability over endurance.

Both cameras accept SD cards; Samsung additionally supports MMC and SDHC standards, offering slightly broader storage options.

Connectivity, Sharing, and More: What About Modern Conveniences?

Connectivity is sparse on both models:

• Casio supports Eye-Fi wireless cards, enabling WiFi transfer of photos for compatible cards but no built-in WiFi.
• Samsung offers no wireless connectivity or GPS.

USB 2.0 ports on both enable wired transfers but lack any form of tethering or remote control.

No HDMI ports or smartphone integration exist.
