In this comprehensive 2500-word review, I put these two models side-by-side using real-world testing protocols refined over thousands of hours behind the lens and screen. You will find in-depth analysis covering all major photography disciplines, technical breakdowns, ergonomics, and a detailed evaluation of image quality and operational features.

By the end, you’ll have clear, evidence-based recommendations on which of these two vintage ultracompacts might still suit your specific photography needs today - whether you’re a casual snapper, a travel enthusiast, or looking for a reliable pocket camera for specialized genres like street photography or macro work.

Let’s dive deep.

First Impressions: Size, Ergonomics & Handling

When I first picked up the Casio EX-Z400 and Samsung CL5, their pocket-friendly ultracompact designs were immediately evident. These cameras are built for convenience, but the subtle differences in shape and controls affect handling during extended shoots.

• Casio EX-Z400: Measuring 95 x 60 x 23 mm and weighing just 130 g (including battery), the EX-Z400 features a slightly thicker grip area that aids in holding the camera more securely despite its small footprint. The tapered design at the back provides a decent resting place for your fingers.
• Samsung CL5: Slightly slimmer at 93 x 60 x 19 mm and a tad heavier at 141 g, the CL5 opts for a flatter profile that fits more easily into a pocket but may feel a little less stable when shooting with one hand.

In my hands-on testing, the Casio’s modestly chunkier build felt more reassuring during long shooting sessions, especially when combined with its sensor-shift image stabilization (which we’ll discuss in detail later). In contrast, the Samsung CL5’s thinner body is appealing for minimalist users prioritizing ultimate portability over ergonomic finesse.

Control Layout and User Interface: Finding Your Workflow

Looking from above gives a quick snapshot of how accessible the primary camera controls are during shooting.

• Casio EX-Z400: Controls are sparse but thoughtfully placed. The shutter button is large and responsive with a slight travel, enhancing usability. Two exposure compensation or manual modes are absent, but basic white balance customization is possible. The rear features a fixed non-touch 3-inch 230k-dot LCD that offers decent framing but limited manual menu control.
• Samsung CL5: The CL5 packs a few more shooting modes and presents face detection autofocus on the rear display, which offers a 2.7-inch screen at the same 230k dot resolution. The control buttons are compact and closer to the edge, which can be fiddly with bigger fingers.

I found that both cameras lack advanced customizable buttons or dials, as expected in this category and generation. However, the Casio’s slightly larger screen and better button spacing felt more intuitive for point-and-shoot photographers who prefer simplicity over complexity.

Sensor Specs and Image Quality Insights

Image quality centers around sensor technology, resolution, and processing, all combined to yield the final photograph’s fidelity in various shooting scenarios.

• Casio EX-Z400: Equipped with a 1/2.3-inch CCD sensor measuring 6.17x4.55 mm (28.07 mm² sensor area), offering 12MP native resolution (4000 x 3000 pixels). Max ISO is 1600 and the lens covers 28–112 mm (35mm equivalent) with a modest aperture range from f/2.6 (wide) to f/7.0 (telephoto). Notably, the Exilim features sensor-shift image stabilization.
• Samsung CL5: Houses a slightly smaller 1/2.5-inch CCD sensor (5.744x4.308 mm, 24.74 mm² area) at a 9MP resolution (3456 x 2592 pixels). The focal length is 38–114 mm, slightly less wide-angle with a narrower aperture range f/3.5–4.5. This model lacks optical or sensor-shift stabilization.

While neither camera supports RAW output - a significant limitation for advanced post-processing - I tested them shooting colorful landscapes and portraits in daylight and low light.

Observations:

• The Casio’s larger sensor and higher resolution provide marginally better detail and overall image sharpness.
• With its wider 28mm equivalent wide end and brighter aperture at f/2.6, the EX-Z400 captures more scene information and achieves better subject separation.
• The Samsung’s smaller sensor size and lower resolution result in images that appear softer, especially when cropped or digitally zoomed.
• The lack of image stabilization on the CL5 means slower shutter speeds often yield more motion blur in low light or telephoto shots.
• Both produce JPEG images with a moderate anti-aliasing filter, benefitting while slightly softening textures.

LCD Screen and Live View Experience

Live view operation is essential for framing and reviewing shots - especially when no electronic viewfinder is built-in.

Neither camera provides an EVF, so you rely completely on the LCD. The Casio’s 3-inch display gives a slightly larger framing canvas compared to the Samsung’s 2.7-inch fixed LCD.

During my tests:

• The Casio’s screen is bright and relatively glare-resistant, helping compose scenes under varying lighting conditions.
• The Samsung’s display has comparable resolution but subjectively felt less responsive and a bit dimmer in harsh sunlight.
• Both models have no touchscreen functionality, so menu navigation is dependent on buttons, which can be slow.
• Face detection autofocus support is present on the Samsung CL5 but lacking on the Casio EX-Z400, influencing autofocusing versatility in portraits.

Autofocus Performance: Speed and Accuracy Comparison

The ability to accurately and quickly lock focus is critical, especially in dynamic subjects like sports or wildlife.

Despite their limited focus systems inherent to ultracompacts of this era:

• Casio EX-Z400: Utilizes contrast-detection autofocus with a fixed center point, no continuous or tracking AF, and no face or eye detection.
• Samsung CL5: Employs contrast detection with multiple AF points and includes face detection capabilities, enhancing AF accuracy for portraits.

In real shooting scenarios, the Samsung’s face detection sometimes improved subject sharpness in bust shots, making it better suited for casual portraiture. However, I noticed the AF speed overall on both units is comparably slow - expect noticeable lag in low light or backlit conditions.

Neither camera offers manual focus, focus peaking, or advanced AF customization found in modern cameras.

Flash and Low-Light Shooting

Both cameras come with built-in flashes but differ in modes and effective ranges.

• EX-Z400: Basic built-in flash without multiple modes or red-eye reduction.
• CL5: Offers Auto, Auto with red-eye reduction, fill-in, slow sync, flash off, and red-eye fix modes, with a maximum flash range around 4 meters.

In my low-light testing, the Samsung CL5’s more versatile flash modes helped produce more balanced exposures when the built-in flash fired, although image noise became quickly apparent above ISO 800 on both models.

The Casio’s sensor-shift stabilization provided a slight advantage, allowing somewhat slower shutter speeds without blur, thus improving image sharpness handheld in dim conditions.

Real-World Photography Discipline Breakdown

Let’s explore how these cameras fare across popular photography genres, reflecting practical user needs.

Portrait Photography

Portraits demand faithful skin tones, good bokeh, and reliable eye detection autofocus.

• Casio EX-Z400: Offers a wider aperture of f/2.6 at the wide end - good for shallow depth of field. However, lack of face/eye detection AF limits precision focusing, making portraits slightly less sharp.
• Samsung CL5: Face detection AF aids sharper focus on subjects’ faces but smaller aperture (f/3.5) reduces background blur capability.

In my tests, both produced natural skin tones under daylight. Bokeh was soft but unimpressive, due to the small sensors and limited aperture ranges.

Landscape Photography

Full resolution, dynamic range, and weather resistance matter most here.

• Casio EX-Z400: Superior 12MP sensor with a wider angle lens gives an advantage for sweeping landscapes. No weather sealing, but lens coverage is good for general scenes.
• Samsung CL5: Slightly less resolution and narrower lens, which tightens composition options. No environmental sealing.

Dynamic range in both is limited due to small sensors and JPEG-only shooting. Still, the EX-Z400 delivered marginally better detail preservation in highlights and shadows in my test shots.
