Casio EX-Z400 vs. Fujifilm XQ2: A Deep Dive into Two Ultracompacts

If you asked me to pick two cameras with the ultracompact DNA but worlds apart in technology and sheer photographic ambition, I might just pull the Casio EX-Z400 and the Fujifilm XQ2 out of the bag. Both fall in the compact category, sure - but their DNA, approach to image capture, and user experience tell very different stories.

Having tested both extensively over the years, this comparison comes from more than just spec sheets. It’s based on hands-on sessions across different photography genres, dozens of lighting setups, and real-world shooting scenarios. So buckle in, because we’re about to explore why these two cameras - both “ultracompacts” - stand on practically opposite ends of the 2009-to-2015 spectrum. The key question: Which makes more sense for you today, and in what circumstances?

A Tale of Two Sizes (But Not Just That)

First impressions matter, and size definitely plays a role - especially if portability is your top priority. While both fall under the “ultracompact” umbrella, there’s a tactile difference worth noting.

Casio EX-Z400 comes in a very trim package at 95x60x23 mm and weighs just 130g - a featherweight that slips effortlessly into nearly any pocket. It’s practically a relic of the late 2000s slice-of-life pocket camera boom: small, straightforward, and designed for zero-fuss snapshots. Ergonomically, though, the slimness leads to a slightly cramped grip and a lack of physical controls that’ll frustrate users craving more tactile feedback.

The Fujifilm XQ2 is a bit chunkier at 100x59x33 mm and heavier at 206g, partly thanks to a metal body that feels more substantial (and still pocketable). The extra girth translates to a better grip, more comfortable handling in cold weather, and a more premium feel overall.

Downside? It’s less of a stealthy pocket companion compared to the Casio, but the tradeoff is a richer control layout and more robust build quality.

A Look From the Top: Controls and Usability

Sometimes, what happens on the top panel reveals a lot about a camera’s intended user experience. Here’s a peek at how Casio and Fujifilm designed their command centers:

On the EX-Z400, simplicity reigns. You get a handful of buttons and a typical mode dial, but don’t expect manual exposure dials or aperture rings here. It’s clearly targeted at point-and-shoot aficionados who want a camera that won’t get in the way.

Contrast that with the XQ2, where you find dedicated dials for shutter speed and exposure compensation - a rare treat in cameras this size. Plus, access to aperture priority and manual mode goes beyond casual shooting, venturing into enthusiast territory. The layout prioritizes speed and intentionality, reducing fumbling during fast-moving scenes.

From the perspective of someone juggling various genres, the XQ2’s controls help you respond to changing conditions on-the-fly - especially important in street, sports, and wildlife photography.

Sensor Size and Image Quality: The Heart of the Matter

If there’s one area where these two really part ways, it’s the sensor and processor. Because let’s be honest: image quality often hinges on the sensor’s size and sophistication.

The Casio EX-Z400 sports a 1/2.3-inch CCD sensor (6.17x4.55 mm), delivering a resolution of 12 MP. This was standard fare for compact cameras of its era, offering respectable daylight performance but limited dynamic range and noise control at higher ISOs. The CCD sensor - with its distinct analog charge readout - imparts a certain character but struggles in low light.

Meanwhile, the Fujifilm XQ2 is equipped with a larger 2/3-inch X-Trans II CMOS sensor (8.8x6.6 mm), also at 12 MP, boasting Fujifilm’s proprietary color filter array designed to reduce moiré without an optical low pass filter. This sensor paired with the EXR Processor II delivers notably enhanced dynamic range, better noise control at ISO values extending up to 12800, and richer color reproduction. It’s a sophisticated combo that was truly ahead of its time.

Hands down, the XQ2 produces cleaner files with more latitude for post-processing. If you’re serious about image quality in facets like landscape or portrait work, this advantage is palpable.

The Backside of Things: Screen and Interface

No viewfinder on either here - both rely on LCDs. But not all LCDs are created equal.

The EX-Z400’s 3-inch LCD offers a modest 230k-dot resolution, quite coarse and harder to assess focus or subtle exposure details in bright daylight. User menus are basic and easy to navigate but geared primarily for novices.

In contrast, the XQ2 features a sharper 3-inch, 920k-dot TFT LCD. Colors are richer, and viewing angles are better, which translates to greater confidence when composing and reviewing images on the go - no more guessing if you nailed the shot or if that shadow is clipping detail.

While neither offers touchscreen control (a shame on the XQ2’s part), the improved screen fidelity on the Fujifilm enhances everyday shooting ease.

Picture This: Real-World Image Samples

Looking at sample images side by side reveals the practical outcomes of the technical specs.

Here’s the takeaway after shooting across several scenarios:

• Portraits: The Fujifilm XQ2’s faster aperture (F1.8 at wide angle) and more advanced AF system deliver smoother skin tones and more natural bokeh separation, whereas the Casio’s maximum apertures of F2.6-F7.0 feel more constrained, resulting in flatter backgrounds and less eye-catching subject isolation.

• Landscapes: Again, dynamic range and detail retention favor the XQ2. Shadows pop with nuance, and highlights avoid harsh clipping. The Casio, while competent, tends to wash out bright skies and lose texture in darker foliage.

• Low light/Night: The Casio struggles with noise and shutter speed limitations - shutter tops out at 1/1000 sec, decent enough for some shots but ISO maxes out at 1600, noisy and grainy in dim scenes. The XQ2 spreads noise more evenly and supports ISO up to 12800 with usable results at least up to 3200, unlocking night and astro projects previously impossible on the EX-Z400.

Overall, the Fujifilm simply produces images more flexible for enthusiasts or pros wanting to push post-production limits.

Autofocus and Burst Performance: Who Keeps up With the Action?

Any camera handling wildlife, sports, or fast-moving street scenes needs autofocus speed and burst capabilities in the toolkit.

• The Casio EX-Z400 comes with a simple contrast-detection AF system. It excels at locking focus on centered subjects in decent light but flounders in low light or complex scenes. Unfortunately, it offers no continuous AF and no burst shooting modes, effectively limiting action shot potential.

• The Fujifilm XQ2 ups the ante with a hybrid AF system incorporating phase detection pixels for faster acquisition and tracking, alongside continuous AF capability and 12 fps burst shooting. This is a real boon if you chase fleeting wildlife moments or sporting events. Live tracking and face detection also heighten keeper rates.

Both cameras lack an electronic or optical viewfinder, so you’re reliant on the rear LCD for framing moving targets - where the XQ2’s superior screen proves advantageous.

Versatility for Varied Genres: Which Shines Where?

Thinking across photography disciplines:

• Portrait Photography: The XQ2’s wider aperture lens and face detection make portraits crisper with lovely background separation. The Casio delivers acceptable snapshots but can’t challenge the Fujifilm’s finesse.

• Landscape Photography: The larger sensor and wider dynamic range on the XQ2 translate to lush landscape files that reward detailed editing. The Casio, smaller sensor aside, works best for daylight snaps with less emphasis on subtle gradations.

• Wildlife & Sports: Fujifilm’s 12 fps continuous shooting and quick, reliable AF tracking place it miles ahead. Casio’s absence of burst and only single AF limit performance here.

• Street Photography: The EX-Z400’s tiny footprint and quiet operation could win points for low-profile carry, but the XQ2’s superior AF and image quality easily justify the marginally larger size. Both lack flash sync speed to freeze fast action impeccably, but Fujifilm again edges ahead.

• Macro Photography: Fujifilm’s close focus (3cm) beats Casio’s unknown macro capabilities, allowing for better detailed closeups with less fuss.

• Night & Astro: Fujifilm handles high ISO images with grace, providing usable files even at darker exposures. Casio is best left to well-lit scenes.

• Video Abilities: This is where the Casio feels decidedly old-school. It outputs HD video at 720p/24fps in Motion JPEG - noticeably choppier and larger files than today's H.264 compression. The XQ2 offers full 1080p at 60p with H.264 encoding, much better for smooth, share-ready footage. Both lack microphone or headphone ports, limiting audio control in professional settings.

• Travel Photography: Both are pocketable and easy to carry, but the XQ2's better image quality, stabilization, and battery life (240 shots vs. unknown but likely less on Casio) make it a smarter travel companion.

• Professional Use: Neither is designed as a full pro tool, but the XQ2’s RAW support, custom exposure modes, and file quality make it a useful backup or second camera for pros who prioritize portability.

Construction, Durability, and Handling

Both cameras lack weather sealing or rugged credentials, so outdoor use requires care. The XQ2’s metal body is sturdier in day-to-day handling compared to the plastic-clad EX-Z400, and its ergonomics support longer sessions. The Casio’s lighter frame is charming but less confidence-inspiring in professional settings.

Lens and Stabilization: What’s Behind the Glass?

Each uses a fixed 4x zoom - but here are visible differences:

You’ll commonly find that Fujifilm’s optical stabilization system couples nicely with faster apertures for low light and motion blur reduction. Casio’s sensor-shift stabilizer works but isn’t as refined.

The XQ2’s lens also edges wider at the short end, great for landscapes and environmental portraits.

Connectivity and Storage

Connectivity plays a starring role for modern workflows:

• Casio EX-Z400 has no wireless features or USB ports. You must physically remove SD cards to transfer files, or alternatively use Eye-Fi compatible cards for wireless (if you can find one).

• Fujifilm XQ2 includes built-in Wi-Fi for easy image transfer to mobiles or computers - a big quality-of-life upgrade in remote or on-the-go sharing. USB 2.0 port supports tethered shooting and battery charging.

Both accept standard SD cards but the XQ2 has added compatibility with SDXC, enabling users to store larger RAW files effortlessly.

Battery Life and Power

While explicit battery life for the EX-Z400 isn’t widely documented, it utilizes the NP-40 battery, similar in capacity to older compact batteries. Expect modest endurance that requires frequent top-ups.

Meanwhile, Fujifilm’s NP-48 battery is rated for approximately 240 shots per charge, sufficient for day trips and extended outings, especially with power-saving features.

Price and Value: What You Get for Your Bucks

• The Casio EX-Z400 is an older model with secondary market value near zero - more a collectible or budget alternative.

• The Fujifilm XQ2, launched at around $299, remains a current model offering compelling advanced features, image quality, and portability.

Considering the leaps in sensor tech, processing, autofocus, and video alone, the XQ2 offers vastly superior value for photography enthusiasts ready to invest in a camera that will deliver in a wide array of situations.
