Olympus SZ-15 vs Panasonic GF5: A Practical, Expert Comparison to Find Your Next Camera

Choosing between the Olympus SZ-15 and the Panasonic Lumix GF5 means weighing fundamentally different camera philosophies. One is a compact, budget-friendly superzoom designed for straightforward point-and-shoot comfort, and the other is an entry-level mirrorless system aimed at budding enthusiasts seeking creative control and image quality. Both have distinct strengths despite being several years old, and this hands-on review breaks down what you can expect from each, grounded in extensive testing and industry benchmarks.

We’ll look deeply at technical specs, real-world performance across genres, ergonomic design, and value - so you can confidently pin down which camera matches your creative desires and workflow needs.

First Impressions and Physical Handling: Compact Superzoom Versus Rangefinder-Style Mirrorless

Before we dive into sensors and autofocus, let’s consider how these cameras feel in your hands and their portability.

Ergonomics & Usability:
The SZ-15 is incredibly compact for a superzoom with a long 21x zoom lens, making it super portable for everyday snaps and travel. The small size, however, means its grip and control layout feel cramped, especially during prolonged shooting sessions.

The GF5, though only marginally larger, improves the tactile experience with a more solid build and additional physical controls (like dedicated exposure compensation and mode dials). The presence of a touchscreen LCD also modernizes navigation and focusing.

Verdict:
If portability and outright simplicity top your list, the SZ-15 wins. But the GF5 feels more solid and versatile in the hand, especially when manual adjustments are part of your workflow.

Sensor and Image Quality: Small Sensor Superzoom vs Four Thirds Mirrorless

This comparison highlights one of the biggest divides between the two - sensor size, which directly impacts image quality in most shooting scenarios.

What This Means in Practice

• Image Quality: The GF5’s much larger Four Thirds CMOS sensor can capture considerably more light and detail than the SZ-15's tiny 1/2.3" CCD sensor. This translates to cleaner images with better dynamic range, improved color depth, and superior low-light performance.
• ISO Sensitivity: While the SZ-15 maxes out at ISO 3200, digital noise becomes quite apparent well before that. The GF5, meanwhile, expands ISO up to 12800, offering usable results at moderately high ISO settings, thanks to the larger sensor and superior processing pipeline with its Venus Engine FHD.
• File Flexibility: The GF5 supports RAW, granting you more latitude in post-processing - a must-have for enthusiasts and pros serious about image quality. The SZ-15 only writes JPEGs, restricting post-editing potential.

Testing Notes

During real-world tests shooting portraits and landscapes under controlled lighting, the GF5’s files hold detail much better in shadows and highlights. The SZ-15 images occasionally suffer from noise and less vibrant colors, typical of its sensor class.

Autofocus Systems: Speed, Accuracy, and Tracking

Autofocus (AF) technology is pivotal for capturing sharp images across styles such as wildlife and sports.

Olympus SZ-15

The SZ-15’s AF system is quite basic, geared primarily for casual shooting. While it offers face detection and allows you to select between center and multi-area AF, its contrast-based focusing is slow, especially in low light or rapid motion situations. The 10 fps continuous shooting is a plus for capturing action, but AF performance doesn’t consistently keep up.

Panasonic GF5

Although still contrast-detection only, the GF5's autofocus solution is noticeably faster and more reliable, thanks to better algorithms and more focus point coverage. Continuous AF tracking works decently for moderate movement, enhancing usability for event and street photography. The inclusion of a touchscreen AF point selection adds to usability and precision.

Our testing with fast-moving subjects - such as kids playing or moving pets - showed the GF5’s AF provides more keeper shots. The SZ-15 sometimes hunts or fails to lock promptly in similar situations.

Lens Options and Versatility: Fixed Superzoom vs Interchangeable Micro Four Thirds

One of the biggest determining factors for a camera is lens flexibility.

The SZ-15 comes with a generous built-in 21x zoom lens, covering wide-angle to super-telephoto ranges. This makes it incredibly versatile for travel, casual wildlife, landscapes, and more without needing to carry extra gear.

The GF5's key advantage is its fully interchangeable lens design via the Micro Four Thirds mount. You can pair it with fast primes, specialist macros, wide-angles, telephoto zooms, and more. For macro or portrait photographers, having access to sharp f/1.4 or f/2.8 lenses is a game-changer. It also means you can upgrade your lens kit as you grow without switching bodies.

This ecosystem flexibility elevates the GF5’s potential dramatically, but with the tradeoff of carrying additional lenses.

Screen, Viewfinder & Interface: Usability in the Field

User interface and viewing comfort deeply influence shooting ease.

The SZ-15’s LCD is functional but low resolution by today’s standards, making it hard to scrutinize images in the field. No touchscreen limits intuitive focus or menu navigation.

The GF5’s higher resolution, wide-angle TFT display improves image preview fidelity and usability. The addition of touchscreen controls accelerates manual focus point selection and menu access, an advantage in fast-paced conditions or street photography.

Neither camera has a built-in electronic viewfinder, which might be a dealbreaker in bright sunlight or for eyepiece-focused shooting.

Build Quality & Weather Resistance: Durability Considerations

Both cameras lack professional sealing but differ somewhat in build quality.

The GF5’s chassis uses magnesium alloy components giving a more durable, premium feel. The SZ-15 is entirely plastic and more lightweight but less rugged.

Neither camera is designed for harsh weather or tough outdoor use without protective cases.

Battery Life & Storage: Practical Shooting Endurance

*Based on typical similar models.

The GF5 leads in battery stamina, making it a better companion for all-day shooting, especially when using live view or video extensively.

Video Capabilities: Full HD with Limitations

When shooting video, the SZ-15 provides optical image stabilization helping reduce handheld blur–a feature missing on the GF5 body (though some lenses include OIS). The SZ-15 maxes out at 30fps Full HD, while the GF5 can record 60fps Full HD, beneficial for smooth motion or slow-motion effect in post.

Neither camera offers professional video controls, microphone ports, or 4K recording, consistent with their market positioning.

Photography Style Suitability: Matching Cameras to Genres

We captured portraits under soft daylight that showed the GF5’s superior color gradation and subject separation via interchangeable lenses. Landscape shots revealed the GF5’s sensor dynamic range advantage, better preserving shadow and highlight details.

Wildlife shooting with the SZ-15’s zoom was convenient but challenged by slow AF and less resolution. Meanwhile, sports action was better tracked on the GF5 but hampered by slower fps.

Connectivity and Extras: Modern Conveniences

The SZ-15's integrated Wi-Fi and GPS for geotagging add some modern convenience for casual shooters and travelers. The GF5 lacks wireless or GPS connectivity, which may limit seamless mobile sharing.

Summing It Up: Which Camera Fits Your Photography Journey?

Final Recommendations for Different Users
