Casio EX-FC150 vs Olympus SZ-31MR iHS: A Detailed Comparison for Enthusiasts and Professionals

Choosing the right compact camera can be a tricky business, especially when the models come from different eras and boast distinct feature sets. Today, I’ll provide a comprehensive comparison between two small sensor compacts designed with superzoom ambitions: the Casio EX-FC150 released in 2009 and the Olympus SZ-31MR iHS that arrived in 2012. Both cameras target photography enthusiasts looking for versatile zoom ranges in pocketable bodies but differ significantly in technology and overall performance.

With over 15 years of hands-on DSLR, mirrorless, and compact camera testing under my belt, I’ll break down their specifications, real-world handling, image quality, and use-case suitability. I’ll also show you how these differences affect various photography styles, from portraiture to wildlife and travel photography. My aim is to help you make an informed decision based on solid experience rather than marketing hype.

Let’s dive in.

First Impressions and Build: Ergonomics and Handling

The physical design and usability of a compact camera have a huge impact on your shooting experience. Let’s start by looking at their size, weight, and control layouts.

Casio EX-FC150 measures approximately 99 x 58 x 28 mm and weighs just 173 grams. Its slim profile makes it extremely pocket-friendly, arguably one of the slimmest in its superzoom class at the time. This minimal build favors portability but sacrifices some handling comfort, especially for users with larger hands or when shooting at full zoom.

Olympus SZ-31MR iHS, by contrast, is larger and slightly heavier at 106 x 69 x 40 mm and 226 grams. While still compact, it feels more substantial and solid in hand, giving a better grip experience, especially given the long 24x zoom. The extra bulk accommodates a more ergonomic design.

Looking at the top control layout, the Olympus offers more refined ergonomics and utilizes illuminated buttons coupled with a touchscreen interface, enhancing usability. The Casio relies on a basic fixed-type LCD screen without touchscreen and an absence of manual exposure controls, limiting direct access to settings during shooting.

Summary:

• Casio’s small size is great for travel and casual use.
• Olympus offers a more comfortable grip and control experience, better suited for extended shooting sessions and varied photography situations.

Sensor and Image Quality: The Heart of the Camera

At the core of image quality lies the sensor technology, resolution, and processor capabilities.

Both cameras use the common 1/2.3-inch BSI-CMOS sensor type measuring 6.17 x 4.55 mm with a sensor area of ~28 mm², but bear notable differences in resolution and processing:

From my extensive testing of similar sensor types, the Olympus’s higher 16 MP resolution provides more detailed images with finer texture rendition, ideal for landscape and travel shots where cropping may be necessary. The Casio’s lower resolution delivers physically larger pixels, which can sometimes yield marginally better noise performance at base ISOs, but the lack of modern processing technology holds it back in low light.

The Olympus supports ISO values up to 6400, offering improved high ISO flexibility, whereas Casio caps out at 1600 ISO. In practical shooting, I found the Olympus to produce cleaner and more usable images at higher ISOs, a decisive advantage for indoor, night, and astrophotography.

Summary:

• Olympus wins on resolution, ISO range, and processing power.
• Casio offers acceptable quality in daylight but struggles beyond ISO 800.

LCD Screens and User Interface

Interacting with your camera via the LCD and controls shapes your photographic workflow substantially.

The Olympus SZ-31MR features a larger 3.0-inch Hypercrystal III TFT touchscreen with sharp 920k-dot resolution, delivering vibrant and detailed previews even under bright outdoor conditions. The touchscreen facilitates quick AF point selection and menu navigation, enhancing responsiveness.

The Casio EX-FC150 is stuck with a 2.7-inch fixed LCD with a low-resolution 230k-dot display, lacking touchscreen capabilities or intuitive interface design. This older-style screen is harder to see in sunlight and offers a more constrained preview experience.

Summary:

• Olympus’s bright, high-res touchscreen provides superior usability and focus control.
• Casio’s screen suits casual shooting but can feel outdated in comparison.

Lens and Zoom Performance: Reaching for Details

Superzoom cameras live or die by their lens capabilities - from wide-angle versatility to telephoto reach.

The Olympus easily outclasses the Casio in zoom range with its impressive 24x zoom covering a super-wide 25mm to an ultra-telephoto 600mm equivalent. This makes it exceptionally versatile - from sweeping landscapes and architecture to distant wildlife and sports.

The Casio’s 5x zoom is modest - more akin to standard compact cameras - adequate only for casual telephoto needs. Its longer minimum wide aperture (f/3.6) limits low-light tele shots slightly, whereas Olympus’s f/3.0 aperture at wide end helps light-gathering for landscape, while the narrower f/6.9 at max zoom is typical but workable with good stabilization.

Macro capabilities favor the Olympus again with a 1 cm minimum focus distance, allowing you to capture finely detailed close-ups, versus Casio’s 5 cm macro limit which restricts very close focusing.

Summary:

• Olympus’s lens provides extraordinary flexibility for nearly every shooting scenario.
• Casio suits casual zoom needs but lacks telephoto reach or macro prowess.

Autofocus System: Accuracy and Speed

Autofocus performance often dictates your ability to capture sharp images in dynamic shooting conditions.

The Casio offers only single-point contrast-detection AF with no tracking or face detection. In my testing, this system is quite basic, slower, and less reliable for moving subjects or complex scenes.

The Olympus, employing the Dual TruePic V processor, brings a more advanced AF system with face detection and tracking capabilities, plus touchscreen AF control, allowing quicker and more accurate focus acquisition. This is a crucial advantage for portraits, street photography, and action shots.

Summary:

• Olympus’s autofocus is more intelligent and responsive, enhancing keeper rates.
• Casio’s limited AF restricts use to static subjects and bright conditions.

Continuous Shooting and Video Capabilities

For photographers capturing fast action or video enthusiasts, frame rate and video specs matter.

The Casio’s 40fps burst mode is notable but typically achieved at drastically reduced resolution or cropped image sizes, which I found limiting in actual use. Olympus’s 7fps at full 16MP resolution is reliable for real-time burst shooting.

Video-wise, Olympus delivers full HD 1080p at 30fps with more efficient H.264 encoding, while Casio tops out at 720p with older Motion JPEG compression, resulting in larger files and lower quality footage.

Neither camera has external microphone inputs, limiting audio quality for serious videographers. Both have sensor-shift stabilization technologies, which proved effective at reducing camera shake especially at longer zooms.

Summary:

• Olympus is superior for both still bursts and video quality.
• Casio’s video is more of a novelty feature with dated specs.

Battery Life and Storage Flexibility

Endurance matters when out shooting.

The Casio’s undocumented battery life left me cautious - typical for older compacts, I recommend carrying spares on longer shoots. Olympus’s rated 200 shots per charge is modest but in line with small compact cameras.

The Olympus supports SDXC cards whereas Casio does not, offering better future-proofing and storage flexibility.

Wireless Connectivity and Extra Features

Both cameras feature Eye-Fi card compatibility for Wi-Fi-like transfer, no Bluetooth or NFC, and lack GPS tagging.

Olympus includes an HDMI output - handy for viewing images and video playback on TVs - which Casio lacks.

Image Samples and Genre Performance

I tested both cameras across a range of photography types and compiled sample galleries to illustrate their strengths and weaknesses in real-world contexts.
