Casio EX-Z2000 vs Nikon Coolpix S6400: The Real-World Ultracompact Camera Face-Off

When it comes to ultracompact cameras - the pocketable shooters that promise to capture your everyday moments without the fuss - two models often surface in vintage discussions: the Casio EX-Z2000, announced in early 2010, and the Nikon Coolpix S6400, unveiled a couple of years later in 2012. Both poke at the same market segment, but do they serve their users equally well? After thoroughly testing both over countless shoots ranging from portrait sessions to wildlife sneaks, I’m here to break down how these two stack up - warts and all.

If you’re hunting for an ultracompact camera in the used market or just curious how these classics compare, buckle up for a deep dive that covers everything from sensor wizardry to ergonomics, and from macro snaps to video chops.

Pocket-Sized Warriors: Handling, Dimensions, and Build

Ultracompacts are all about convenience - they live in your pocket or small bag, begging for spontaneous clicks. So let’s first see which of these little guys feels better in hand and in your daily grind.

Looking at their physical dimensions, the Casio EX-Z2000 measures 99 x 58 x 17 mm, making it slightly slimmer than the Nikon’s chunkier 95 x 58 x 27 mm body. At 152 grams, Casio is marginally heavier than Nikon's 150 grams, but the difference is negligible in real terms.

The more elongated Casio favors a thinner profile, which can slide into tighter pockets comfortably. However, that slenderness also translates to less grip space and fewer clubs for your thumbs and fingers to hang onto. The Nikon, while thicker, offers a slightly more substantial hand feel - helpful when you’re out shooting for hours and don’t want sweaty fingerprints slipping on the chassis.

Build Quality and Materials

Neither camera boasted environmental sealing or rugged construction - no splash or dust resistance on either. Both feel typical of budget ultracompacts of their era, with plastic bodies and modest durability. The Nikon’s build is a tad more refined, showing fewer creaks under pressure, which I attribute to Nikon’s overall superior attention to ergonomics and finishes in this range.

Control Layout

While examining the top plate and control array, Nikon’s interface edges out with its updated Expeed C2 processor supporting features like touch operation - a welcome aid for navigating menus quickly. The Casio relies on physical buttons, with no touchscreen, which means more clubs for thumbs but also potentially slower setting changes.

Buttons on the Nikon are easier to reach and more purposefully spaced, supporting features like face detection toggling. The Casio’s controls feel a bit cramped, and the absence of dedicated exposure modes means fewer options to quickly adjust settings on the fly.

Sensors, Image Quality, and Performance Metrics

Under the surface, image quality hinges overwhelmingly on sensor design, resolution, and processing. These two cameras take markedly different approaches.

Sensor Tech and Size

Both cameras share the same 1/2.3-inch sensor size (6.17 x 4.55 mm), typical for ultracompacts. However, the Casio EX-Z2000 uses a older CCD sensor with 14 megapixels, while the Nikon S6400 opts for a more modern 16-megapixel, backside-illuminated (BSI) CMOS sensor.

What this means in practice: The Nikon’s BSI-CMOS sensor excels in low-light with better noise control, while the Casio’s CCD struggles at high ISO, quickly losing image fidelity beyond ISO 400. The difference in sensor technology is one of the biggest deciding factors here.

Resolution and Detail

Nikon’s 16MP output at 4608 x 3456 pixels slightly edges Casio’s max resolution of 4320 x 3240, offering more detail capture - useful if you want to crop heavily or print at larger sizes. Despite this, expect both cameras to deliver decent prints up to 8x10 inches but avoid enlargement beyond that with either.

In side-by-side real-world testing on fine detail scenes - like textured fabrics and foliage - the Nikon’s sensor and processing pipeline produce crisper, more natural images. Casio’s photos can sometimes appear softer, especially towards the edges, hinting at legacy image processing limitations.

Dynamic Range and Color Rendition

Neither camera was ever tested by DxOMark for dynamic range and color depth, but my hands-on experience points to Nikon’s more capable sensor pulling better highlight retention and richer color gradations, especially in shadowy outdoor settings.

Casio’s images tend to clip highlights quicker under harsh sunlight, and the CCD’s color reproduction feels punchier but less natural overall.

LCD and Viewfinder: Framing Your Shot

Neither camera offers an electronic viewfinder, so LCD screen quality becomes especially important for composing images outdoors.

Both sport a 3-inch fixed-type screen with about 460-461k dot resolution - not much to differentiate there visually. However, the Nikon S6400 boasts a TFT LCD with touchscreen capability, which vastly improves navigation and focus point selection during shooting.

Casio’s non-touch, fixed-type display means more button mashing and menu diving, slowing down operation. Neither screen is particularly bright - decent enough in moderate light but frustrating under bright sunlight without a hood or shade.

Autofocus and Shooting Performance: Timing and Accuracy Matter

Focusing is crucial - especially when subjects don’t wait around. Here’s where Nikon’s tech leap becomes apparent.

• Casio EX-Z2000 autofocus: single, contrast detection system only; no face or tracking AF support.
• Nikon S6400 autofocus: contrast detection with face detection, multi-area and center-point AF; supports AF tracking on moving subjects.

With no continuous AF on either, both cameras struggle with moving subjects, but Nikon’s face detection and tracking help keep more shots in focus during casual human portraits or street photography outings.

The Casio’s autofocus tends to be notably slower in dim environments, and hunting can be frequent enough to cost missed shots. The Nikon is snappier overall with faster lock times and fewer misses - especially in decent light.

Zoom Range and Lens Quality: Flexibility vs Aperture Trade-offs

Zoom versatility is often a make-or-break factor for compact buyers. Here the Nikon S6400 flexes major muscle with a 25-300mm equivalent 12x optical zoom. In contrast, the Casio EX-Z2000 sticks to a much more modest 26-130mm 5x zoom.

That means Nikon covers everything from wide-angle cityscapes to somewhat decent reach into telephoto territory - for wildlife and sports, albeit limited by sensor size and autofocus. Casio’s zoom is more suited for casual landscapes and portraits, rarely stretching far past moderate telephoto.

Unfortunately, both cameras’ maximum apertures taper quickly at longer focal lengths - the Casio going from F2.8 to F6.5, Nikon from F3.1 to F6.5 - limiting low-light telephoto efficacy.

In real-world shooting, Nikon’s longer zoom blew me away for travel and street flexibility, letting me traverse scenes without changing lenses or sneaking close. Sharpness at the longest zoom settings drops mildly but remains usable for casual prints.

Real World Across Photography Genres

Let’s break down strengths and weaknesses for different use cases based on my testing experience:

Portrait Photography

• Casio EX-Z2000: No face detection autofocus, so nailing tack-sharp portraits - particularly eye-level focus - can be hit-or-miss. The fast-ish F2.8 aperture at wide end helps modestly with background separation, but softer lens rendering reduces bokeh quality. Skin tones are decent but can feel artificially vivid.
• Nikon S6400: Face detection AF definitely improves portrait IQ by focusing precisely on eyes and faces. Slightly slower aperture at F3.1 lessens shallow depth of field artsiness but produces more natural skin tones and smoother background blur.

Winner: Nikon, hands down, for its smarter autofocus and more natural rendering.

Landscape Photography

• Casio EX-Z2000: Limited zoom and moderate sensor resolution restrict compositional framing and output size. Dynamic range is narrower, so bright skies can blow out easily.
• Nikon S6400: Longer zoom enables framing versatility; better sensor dynamic range retains detail in highlights and shadows. Slight edge for landscapes, especially with longer focal lengths.

However, neither camera has weather sealing, so caution needed in harsh outdoor environments.

Winner: Nikon for versatility and better sensor performance in daylight.

Wildlife and Sports Photography

Let’s be real here: ultracompacts aren’t sports pros. But between the two:

• Casio EX-Z2000: Slow autofocus, no continuous AF or high burst rates. 5x zoom falls short for distant subjects.
• Nikon S6400: Faster autofocus with tracking, longer 12x zoom, and slightly faster shutter (up to 1/4000s vs Casio’s 1/2000s) deliver improved performance for action shots.

Still, no rapid-fire frame rates or advanced AF modes. Better off with dedicated super-zooms or DSLRs.

Winner: Nikon, albeit with caveats.

Street Photography

Discretion counts - small size, silent operation, and quick AF help here.

• Casio EX-Z2000: Slimmer and quieter (sensor-shift stabilization, CCD sensor), but slow AF can frustrate street shooters.
• Nikon S6400: Slightly thicker but with quick AF and effective face detection. Touchscreen helps rapid composition.

Neither is perfectly stealthy, but Nikon’s responsive AF favors decisive moments.

Winner: Nikon for responsiveness; Casio for slimness.

Macro Photography

• Casio EX-Z2000: No dedicated macro focusing distance specs; limited by fixed lens design.
• Nikon S6400: Offers 10cm macro focus, allowing more detailed close-ups.

Nikon’s advantage here is clear for flower or small object shots.

Winner: Nikon.

Night and Astrophotography

Both limited by sensor sizes and lenses. Nikon’s BSI sensor does better with noise at high ISO settings. Casio cannot shoot RAW, which limits post-processing recovery.

Winner: Nikon for cleaner high ISO results and more usable images under dim conditions.

Video Capabilities

• Casio EX-Z2000: Maximum 720p at 30fps, saved as Motion JPEG; no external audio input.
• Nikon S6400: Full HD 1080p at 30fps, MPEG-4 and H.264 codecs; more modern formats; HDMI out. Also lacks microphone input.

Nikon’s video offers higher resolution, better encoding, and smoother footage.

Winner: Nikon.

Travel Photography

Nikon’s versatility, zoom range, and touchscreen offer great appeal for the traveler wanting a one-camera solution compact enough for carry-on bags.

Casio’s slimmer size and stabilization work for casual snapshots, but zoom and slow AF limit use cases.

Winner: Nikon for versatility and convenience.

Professional Work and Workflow Integration

Both cameras lack RAW support, limiting pro workflows. Connectivity is modest - only Eye-Fi card wireless photos and USB 2.0 for data transfer. No Bluetooth or GPS.

Neither can claim professional reliability or integration advantages.

Internals and Usability

Battery Life

The Nikon S6400 offers a rated 160 shots per charge - typical for ultracompacts of the time but still modest. Casio’s battery life isn’t clearly stated but likely similar or slightly less. In my shoots, both required extras or quick charging for full-day outings.

Storage

Both accept SD/SDHC cards, though Nikon also supports SDXC for higher capacities, a practical advantage.

Stabilization

• Casio uses sensor-shift (CCD) stabilization which proved fair but not class-leading.
• Nikon employs optical image stabilization in lens, usually better for telephoto shots.
