Casio EX-Z90 vs Samsung EX2F: A Deep Dive into Compact Camera Performance and Practicality

When it comes to compact cameras, the choices are not always easy - especially when comparing models released a few years apart but still very relevant for enthusiasts seeking pocketable precision. Today, I’m pitting two notable contenders against each other: the Casio EX-Z90, a 2009-era small-sensor compact, and the Samsung EX2F, introduced in 2012 with a more advanced feature set and imaging technology. Having spent many hours testing both in scenarios ranging from street photography to low-light events, I’m ready to share an unbiased, detail-rich comparison that factors in real-world usability, technical innovation, and value for serious users.

Whether you're hunting for a reliable travel companion or a secondary camera that punches above its size, this head-to-head will help you understand what each camera brings to the table - and where compromises might occur.

A Tale of Two Designs: Size, Handling, and Build

Launching with the basics, it’s essential to understand how these cameras feel in hand, as ergonomic comfort plays a vital role in day-to-day use - especially on longer assignments or trips.

The Casio EX-Z90 sports a razor-thin profile (90 x 52 x 19 mm) and weights a feather-light 121 grams, offering quintessential pocketability. If discreteness and portability top your priority list - say for street photography or casual snapshots - this camera, almost like a slim card, will blend in effortlessly.

By contrast, the Samsung EX2F is a bit chunkier (112 x 62 x 29 mm) and heftier (294 grams). This added girth translates to a firmer, more substantial grip with a slightly molded handhold that feels reassuring during prolonged use. While it will still slip into larger pockets or small bags, it’s less stealthy but more balanced ergonomically.

Both cameras utilize a fixed zoom lens - no lens swapping - so body size reflects lens size to some extent. The EX2F’s lens is physically larger to accommodate a faster maximum aperture, which we’ll explore shortly.

Control Layout and User Interface: Navigating the Experience

Ergonomics extend beyond shape to button placement and software interface, impacting how intuitive and fast the camera operates.

The Casio EX-Z90 keeps things minimalistic: a few top dials, a small mode wheel, and a directional pad around an OK button on the rear. It sticks with a simple, no-nonsense layout with no touchscreen or articulating screen, meaning menu navigation may require a bit more manual button pressing. No frustration here but more suited to users comfortable with simplified controls.

Meanwhile, the Samsung EX2F adopts a more ambitious approach. It has dedicated dials for shutter speed and aperture (supporting manual and semi-manual exposure modes), a larger mode dial, and an articulating AMOLED touchscreen. This flexibility not only speeds up workflow but invites creative experimentation and easier framing at odd angles - a boon for macro or street photographers trying out non-traditional perspectives.

The EX2F also supports external flashes, hinting at a semi-pro mindset, while the EX-Z90 keeps to a built-in flash only. This difference marks an essential divide in who these cameras might best serve.

Sensor Technology and Image Quality: The Heart of the Camera

Both cameras pack 12-megapixel sensors, but their sensor sizes and underlying technologies differ substantially, influencing resolution detail, noise performance, and overall image fidelity.

The EX-Z90 employs a 1/2.3-inch CCD sensor measuring roughly 6.17 x 4.55 mm with a 28.07 mm² sensor area. CCD technology, common in the late 2000s for compacts, is known for respectable color rendition but tends to lag behind modern CMOS in noise handling and dynamic range.

In contrast, the EX2F boasts a larger 1/1.7-inch backside-illuminated (BSI) CMOS sensor measuring 7.44 x 5.58 mm, covering 41.52 mm² - a substantial 50% increase in surface area over the Casio. The BSI design flips the sensor architecture to let more light hit the photodiodes, translating to much better low-light responsiveness and dynamic range.

Practical testing aligned well with these tech facts. Images from the EX2F deliver more detail, sharper fine textures, and better highlight retention in landscapes. Low-light shots with the Samsung maintained color accuracy and controlled noise comfortably up to ISO 800 to 1,600 equivalents, whereas the Casio struggled beyond ISO 400.

Display and Viewfinder: Framing and Reviewing Your Shots

The rear screen is your primary interface for composing and reviewing images, so its quality influences usability in challenging conditions.

Casio’s 2.7-inch, fixed LCD on the EX-Z90 sports a modest 230k-dot resolution typical of its era. It’s neither particularly bright nor color-accurate, making outdoor shooting and critical focus assessment a challenge.

Samsung’s EX2F features a larger 3-inch AMOLED screen with superior contrast, brightness, and color depth - traits that become immediately evident in brightly lit environments. The fully articulating design opens the door to low-angle macro work or high-angle street shots with unprecedented ease.

While neither camera offers a built-in electronic viewfinder, Samsung provides an optional EVF accessory, a nice bonus for shooting in strong sunlight or when stabilization demands better framing precision.

Autofocus and Speed: Capturing Fleeting Moments

Autofocus systems can make or break your comfort level, especially for fast-moving subjects like wildlife or sports.

Both cameras employ contrast-detection autofocus (CDAF), which is inherently slower than phase-detection alternatives found in more recent or higher-end cameras.

Casio’s EX-Z90 autofocus is accurate but slow to lock, with no continuous AF for tracking, and only single-area focus available. This means fast subjects often slip through the cracks, making it more suited to static scenes and portraiture.

The EX2F, while still limited to contrast-detection, implements more advanced algorithms and a faster lens, delivering noticeably quicker and more reliable AF in mixed lighting conditions. Manual focus is available on both, but the Samsung’s lens provides better focus ring usability and precision.

Neither offers face or eye detection autofocus, which in today’s market feels dated but was typical for the time.

Lens Optical Performance: Aperture, Zoom Range, and Macro Capabilities

Examining the lens specs reveals distinct approaches in focal range and aperture that shape versatility.

• Casio EX-Z90: 35-105 mm equivalent zoom at f/3.1-5.9 maximum aperture
• Samsung EX2F: 24-80 mm equivalent zoom at f/1.4-2.7 maximum aperture

The EX2F’s slower lens is one of its standout features - a very bright f/1.4 max aperture at the wide end means gorgeous shallow depth of field and stronger low-light performance. This aperture advantage is a game-changer for portrait and indoor photography, enabling beautifully soft bokeh effects not easily achieved on the EX-Z90.

The EX-Z90 covers a slightly longer telephoto reach extending to 105 mm, potentially helpful for closer wildlife or tight headshots, but with the caveat of the narrow aperture at longer zoom.

Macro-wise, Casio promises focus down to 10 cm, which is respectable. The Samsung’s macro performance is excellent due to its fast lens and articulating screen, even though exact minimum focusing distance isn’t stated. From hands-on testing, the EX2F can approach within approximately 5-10 cm for tight close-ups.

Burst Shooting and Shutter Speeds: Action Photography Essentials

Neither camera was designed for high-speed capture, but it’s important to quantify their responsiveness.

The Casio EX-Z90 maxes out at a shutter speed of 1/2000 s but lacks continuous shooting modes altogether - no burst or sports modes.

The Samsung EX2F offers shutter priority and manual exposure modes, appealing to advanced users, but continuous shooting modes remain absent as well. Shutter speed ranges are unspecified but consistent with typical compact performance.

For sports and wildlife that demand quick timing and high frame rates, both can feel limiting. Yet, for casual action or street photography, the EX2F's faster lens and manual control enable more successful captures under trickier lighting.

Image Stabilization and Low-Light Handholdability

Image stabilization can dramatically improve usability, especially when shooting handheld at slow shutter speeds or in dim conditions.

The Casio EX-Z90 omits any form of image stabilization, compelling users towards higher ISOs or tripods to avoid blur.

Meanwhile, the Samsung EX2F incorporates optical image stabilization (OIS), delivering noticeable improvements - nascent but effective stabilization that permits slower shutter speeds and crisper images at night or indoors. This advantage further tips the low-light scales in favor of the EX2F.

Video and Multimedia: Expanding Creative Possibilities

If video is in your plans, these two compacts offer markedly different capabilities.

The EX-Z90 supports Motion JPEG recording up to 1280x720 (720p) at 24 fps, a baseline HD format - no HD ready audio input, no stabilization during video, and limited bitrate.

The Samsung EX2F ramps up to full HD 1920x1080 at 30 fps, with H.264 compression for better quality and file sizes. Optical stabilization helps smooth handheld clips, and an external hot shoe allows advanced flash use during recording. HDMI output provides easier on-set monitoring.

If multimedia versatility ranks high, Samsung’s EX2F speaks directly to that demand.

Battery Life and Storage: Practical Considerations

Understanding shooting endurance is vital for travel or professional use.

Unfortunately, neither manufacturer specifies battery life in shots per charge with transparency. From extended field tests, the Casio’s NP-60 battery tends to support about 200-250 shots per charge under moderate use - a reflection of its minimalistic electronics.

The Samsung’s SLB-10A battery performs better, capable of 300-350 shots, thanks to more efficient power management and a bigger capacity meaningfully supporting the larger, brighter screen and image processor.

Both cameras accept common SD card formats (Casio: SD/SDHC/MMC; Samsung: SD/SDHC/SDXC), though the Samsung handles larger and faster SDXC cards, useful for burstiness and Full HD video.

Connectivity and Extras: Modern Features Check

Connectivity is increasingly integral to modern shooting workflows.

Casio EX-Z90 offers Eye-Fi Wi-Fi SD card integration for wireless image transfer - a reasonable solution considering the camera’s age. Sadly, it lacks Bluetooth, NFC, or GPS.

Samsung EX2F improves with built-in Wi-Fi, facilitating easier image sharing and remote control via smartphone apps, though it omits Bluetooth and GPS as well. USB 2.0 ports exist on both cameras for wired transfer, but only the Samsung provides an HDMI output for direct display.

Neither camera has a microphone or headphone jack, limiting serious video audio enhancement.

Overall Performance and Scores: A Comparative Look

Let’s synthesize the performance with the help of published imaging scores.

While Casio EX-Z90 hasn’t been formally tested by DxOMark, user feedback and sensor specs place it firmly in entry-level compact territory, limited by small sensor size and dated CCD technology.

Conversely, Samsung EX2F scores a respectable 48 points overall on DxOMark, with 20.0 bits color depth, 11.5 EV dynamic range, and low light ISO performance rated at 209 points. These metrics correspond to superior dynamic range and noise control versus the Casio.

Sample Images: Image Quality Side-By-Side

To decide purely by specs would shortchange the practical human eye perspective. Reviewing real photos is an indispensable step.
