Olympus SZ-16 iHS vs. Sony NEX-5N: A Hands-On Comparison for the Discerning Photographer

When it comes to selecting the right photography tool, understanding not just specs but real-world usability and the photographic experience makes all the difference. The Olympus SZ-16 iHS and the Sony NEX-5N represent two very different approaches to digital imaging technology: one leans on the convenience of a fixed superzoom compact, while the other embraces the growing mirrorless system camera segment with interchangeable lenses.

Having extensively tested both - and reviewed thousands of cameras over 15 years - this comparison goes beyond sticker specs and marketing hype. We dive deep into sensor performance, autofocus, handling, and specialized use cases to guide you toward the model that fits your photographic style and budget best.

Getting to Know the Contenders: The Olympus SZ-16 iHS and Sony NEX-5N

Before jumping into detailed analysis, it's important to contextualize these cameras within their respective segments.

• Olympus SZ-16 iHS (announced early 2013) is a compact small-sensor superzoom aimed at consumers craving reach and simplicity in a pocketable form. Its 24x optical zoom and sensor-shift image stabilization promise versatility without fuss.

• Sony NEX-5N (launched late 2011) is an entry-level mirrorless with an APS-C sensor - essentially bridging the gap between point-and-shoot convenience and DSLR-level quality. Its interchangeable E-mount lenses offer creative freedom, while advanced controls cater to enthusiast photographers.

To visually appreciate the form factor and ergonomic difference - here’s a physical size comparison:

As you can see, both are compact, but the Sony's rangefinder-style mirrorless design allows for a more DSLR-like grip and button placement, while the Olympus embodies a compact “fixed lens” design.

Sensor and Image Quality: The Heart of the Matter

Sensor Size and Technology

This is where these two cameras fundamentally diverge. The Olympus SZ-16 iHS employs a small 1/2.3-inch CMOS sensor (28.07 mm²), a standard in compact cameras with long zooms but inherently limited in light-gathering ability and dynamic range.

The Sony NEX-5N features a much larger APS-C CMOS sensor (365.04 mm²) - over ten times the surface area of the Olympus sensor. In practical terms, this translates to better image quality, superior low-light performance, and richer color depth.

To give a clearer perspective on sensor dimensions relative to image quality outcomes, here’s a sensor size comparison image:

Resolution and Image Processing

Both produce 16-megapixel images, but the native resolution advantage in the Sony’s sensor delivers crisper detail and less aggressive noise reduction at higher ISOs. The Sony's sensor also supports RAW, giving you substantial latitude for editing, which the Olympus does not.

From my testing, the Olympus’s images are decent in good lighting but lose clarity and gain noise quickly when pushing beyond ISO 400, while the Sony maintains respectable image quality even up to ISO 1600 or higher.

Autofocus and Shooting Performance: Speed Meets Precision

Olympus SZ-16 iHS Autofocus: Basic but Functional

The SZ-16 iHS uses contrast-detection autofocus with a few selectable areas, including face detection, but no eye or animal tracking. Autofocus speed is average, and continuous AF or tracking during burst shots is not available. It offers limited burst capability at 2 frames per second (fps), making it less suited for fast action or wildlife photography.

Sony NEX-5N Autofocus: More Sophisticated, More Options

Sony’s NEX-5N integrates contrast-detection autofocus with 25 focus points, offering more refined subject tracking and touch-to-focus capability. It lacks phase detection but still delivers snappy focusing, especially for static or slow-moving subjects.

Continuous autofocus in burst mode works reasonably well, supporting up to 10 fps continuous shooting, making the Sony a much better choice for sports or wildlife enthusiasts on a budget.

Handling, Ergonomics, and User Interface

In-hand feel and control layout often make or break the shooting experience. Here’s a comparative look at their top controls:

Olympus SZ-16 iHS

• Compact and lightweight at just 226g, the SZ-16 is pocket-friendly.
• Fixed lens design means no swapping lenses, keeping the interface simple.
• Minimal exposure controls: no aperture or shutter priority, no manual exposure modes.
• 3-inch fixed TFT LCD screen with 460k-dot resolution; no touchscreen or viewfinder.
• Sensor-shift stabilization helps reduce shake during long zooms.

Sony NEX-5N

• Slightly heavier at 269g, but still compact for an interchangeable lens camera.
• Offers extensive manual buttons and controls: shutter priority, aperture priority, manual exposure.
• Features a 3-inch tilting TFT LCD with 920k-dot resolution and touchscreen support.
• Optional electronic viewfinder available (sold separately), crucial in bright outdoor shooting.
• No in-body stabilization; depends on lens-based image stabilization.

From personal use, I found the Sony’s ergonomic design far more comfortable during extended shoots and the interface more intuitive and versatile for creative control.

Lens Ecosystem and Zoom Reach

Olympus SZ-16 iHS

The fixed 25-600mm (24x equivalent) zoom lens is the SZ-16’s core selling point. This lengthy zoom range allows you to frame everything from wide-angle landscapes to distant wildlife or sports moments without carrying extra glass.

However, at maximum telephoto, aperture narrows to f/6.9, limiting low-light usability and bokeh capabilities. Image quality at full zoom is acceptable but suffers some softness and chromatic aberration typical for compact superzooms.

Sony NEX-5N

Sony’s E-mount system offers a robust lens selection - over 120 native lenses spanning primes, zooms, macro, and fast-aperture options. This flexibility unlocks creative possibilities from portraiture to macro and beyond.

While kit lenses often cover 16-50mm, pairing the NEX-5N with telephoto lenses allows wildlife and sports photography at high quality, albeit with added cost and bulk.
