Casio EX-ZR100 vs Samsung ST150F: A Thorough Comparison of Small Sensor Compact Cameras for Enthusiast Photographers

In the vast arena of compact digital cameras, enthusiasts often search for models that strike the right balance between portability, versatility, and image quality. Today, we dive deep into two such contenders from the early 2010s: the Casio EX-ZR100 and the Samsung ST150F. While both fall under the “small sensor compact” umbrella, their specifications and design philosophies offer distinct shooting experiences. Having spent extensive hands-on time with both models, I’ll unpack their core technologies, practical strengths, drawbacks, and most importantly, how each stands up in real-world photography scenarios across multiple genres.

What’s In Their DNA? Physical and Ergonomic Differences

At first glance - and feel - the Casio EX-ZR100 and Samsung ST150F cater to slightly different sensibilities despite their shared compactness. Measuring 105x59x29mm and weighing 204g, the Casio is larger and more substantial than the 94x58x18mm, 114g Samsung.

Holding the Casio EX-ZR100 conveys a more confident grip, thanks to its thicker body and a modestly pronounced thumb rest. This makes it especially comfortable for extended sessions or when paired with longer zoom lenses, which we’ll delve into shortly. Meanwhile, the Samsung ST150F trades heft for extreme portability, fitting effortlessly into pants pockets and smaller bags.

This size difference inherently sets some expectations around handling characteristics and stability. Heavier cameras like the EX-ZR100 tend to reduce hand shake and generally feel more balanced during manual operations. The Samsung, with less physical mass, will require a steadier hand or tripod support in low-light conditions.

Taking a closer look at the top control layout (see below), Casio’s approach is geared towards enthusiasts who like manual control options - aperture priority, shutter priority, and full manual mode - none of which are found on the Samsung, which is decidedly targeted towards simple point-and-shoot users.

These distinctions are subtle but important. The EX-ZR100’s dedicated dials, buttons, and exposure compensation control give photographers direct tactile access to core settings - something I appreciate having when switching quickly between different shooting modes in demanding environments. The ST150F offers a more minimalistic control layout, leaning heavily on the automations and presets Samsung baked into its software ecosystem.

Sensor, Image Quality, and Processing: The Heart of the Matter

Both cameras use a 1/2.3-inch sensor type - standard for their class - but they differ fundamentally in sensor technology and resolution:

• Casio EX-ZR100: 12MP Backside Illuminated CMOS sensor
• Samsung ST150F: 16MP CCD sensor

The EX-ZR100’s BSI-CMOS sensor marks a significant advantage - it’s designed to maximize light capture efficiency, particularly in low light, by flipping the wiring to the back of the sensor, thereby allowing more photons to reach the photodiodes. On the other hand, the Samsung employs a CCD sensor, which historically excels in color fidelity and results in slightly finer gradations but tends to generate more noise at higher ISO settings and is generally slower for burst shooting.

In my testing across various lighting environments, this difference was palpable. The Casio’s sensor and its “Exilim Engine HS” image processor handle noise impressively, maintaining good detail even at ISO 800 and 1600, whereas the Samsung’s noisy output began to degrade significantly at ISO 400 and above.

The Samsung’s higher resolution of 16MP doesn’t translate convincingly into sharper images given sensor noise and lens quality limitations. In fact, optical performance - lens sharpness, distortion control - plays a critical role in the final pixel-level detail.

Lens and Zoom Capability: Versatility Wins on Casio’s Side

Zoom range is a classic differentiator in superzoom compacts. The Casio EX-ZR100 sports a 24-300mm equivalent focal range (12.5× zoom), while the Samsung ST150F offers a more modest 25-125mm equivalent zoom (5×).

This difference is quite telling. The EX-ZR100 effectively doubles the telephoto reach compared to the ST150F, which opens possibilities beyond casual snapshots - think wildlife on hikes, sporting events, or architectural details at a distance.

However, the Casio’s aperture drops from F3.0 wide-open at 24mm to a relatively slow F5.9 at 300mm - typical of long superzooms - not ideal for very low-light telephoto shooting. The Samsung starts wider at F2.5 but only zooms out to F6.3, and given its shorter zoom, it’s less versatile for distant subjects but better for moderate lighting conditions.

From a practical perspective, the EX-ZR100’s enhanced zoom leverage, combined with effective sensor stabilization (sensor-shift IS), makes it the better choice for dynamic scenes requiring focal length flexibility. The Samsung lacks any image stabilization, which impacts sharpness at longer focal lengths and slower shutter speeds.

Screen and Interface: Viewing Experience and Handling in the Field

When shooting outdoors or in rapidly changing environments, screen clarity can make or break your experience.

The Casio EX-ZR100 sports a 3.0-inch “Super Clear TFT” LCD with 461k-dot resolution. The Samsung ST150F also has a 3-inch but with QVGA TFT and only 230k-dot resolution.

In bright daylight, I found the Casio’s screen noticeably more legible, with better contrast and improved viewing angles. The instant visual feedback on the Casio’s screen was a definite advantage during landscape and street photography sessions. This is important because, without an electronic viewfinder (both cameras lack one), relying on the LCD is the only framing option.

The Samsung’s screen feels somewhat underwhelming given its low resolution, making precise focusing or critical composition less intuitive. Additionally, neither camera offers a touchscreen, so menu navigation is via physical buttons only - an area where neither excels but is typical for compact cameras of this era.

Autofocus Systems and Speed: Tracking Your Subject

Autofocus (AF) is one of the most critical features for capturing sharp images in all genres, especially action-related ones like wildlife and sports.

Both cameras employ contrast-detection autofocus with multi-area detection capabilities. The Samsung ST150F offers face detection and center-weighted AF, while the Casio EX-ZR100 lacks face detection but includes multiple focus areas.

During field tests with moving subjects, I noticed that the Casio’s AF response time was snappier, thanks in part to its faster processor and newer technology. The ability to switch between single AF and full tracking modes on the EX-ZR100 aids in keeping focus locked on dynamic subjects.

The Samsung’s face detection is user-friendly, especially for casual portraits or group shots, but the overall AF speed felt slower and less reliable when tracking moving subjects.

Shooting Performance: Burst, Shutter Speed, and Low Light

For burst shooting, the Casio EX-ZR100 can shoot up to an impressive 40 frames per second (fps) in continuous mode, though this is likely at reduced resolution or JPEG-only mode given the hardware limitations. The Samsung ST150F doesn't specify continuous shooting rates, hinting at less robust burst performance.

This speed difference makes Casio’s EX-ZR100 a much better option for capturing fleeting moments - sports, fast wildlife movements, or candid street photography.

Shutter speed ranges also differ somewhat:

• Casio: 15s to 1/2000s
• Samsung: 1s to 1/2000s

The Casio’s longer maximum exposure time (15 seconds) allows for more creative options such as night photography or light trails.

In practical low-light usage, the Casio’s sensor paired with built-in image stabilization also outperforms the Samsung’s CCD sensor and lack of IS. I achieved usable handheld shots in dim conditions with the Casio at ISO levels where the Samsung struggled to deliver sharp images without blur.

Video Capabilities: Are There Clear Winners?

If you’re considering video alongside stills, it’s important to examine specifications and real-world results.

The Casio EX-ZR100 supports Full HD (1920x1080) recording at 30fps, leveraging its H.264 compression. The Samsung ST150F tops out at 720p HD at 30fps with MPEG-4 and H.264 support.

Neither has microphone or headphone jacks, limiting audio control. Stabilization is only present on the Casio, offering smoother handheld footage. While neither camera excels as a dedicated video tool, the Casio’s higher resolution and stabilization make it the more versatile hybrid shooter for occasional video work.
