Nikon Coolpix A900 vs Olympus SZ-15: A Deep Dive into Compact Superzoom Cameras

When it comes to compact superzoom cameras, enthusiasts and professionals alike face a crowded market filled with models that often blur the lines between beginner-friendly convenience and advanced photographic control. Today, I’m putting two modest but intriguing contenders head-to-head: the Nikon Coolpix A900 and the Olympus SZ-15. Both cameras target shooters who want extensive zoom ranges in a pocketable form factor but differ markedly in their details, execution, and overall performance.

Drawing from over 15 years of hands-on camera testing and the evaluation of thousands of models, this comparison aims to go beyond the spec sheet. We’ll assess real-world usability, image quality, autofocus performance, video capabilities, and more. Whether you’re a casual traveler, aspiring wildlife photographer, or someone simply craving a straightforward yet versatile zoom camera, this guide should clarify what each model truly offers.

First Impressions: Size, Handling, and Ergonomics

Before diving into the technicals, how these cameras fit in your hand - both physically and in terms of user interface - is crucial. Neither has an interchangeable lens (both fixed zoom lenses), but in compact zooms, body design and control layout greatly influence shooting comfort, especially during extended use.

Looking at the physical dimensions and weight, the Nikon A900 measures roughly 113x67x40 mm and weighs 289 grams. The Olympus SZ-15 is slightly more compact and lighter at 108x70x40 mm and 250 grams. In hand, this difference isn’t dramatic, but the smaller footprint of the Olympus offers a marginal edge in portability, making it more pocket-friendly for travel or street photographers who want to carry light.

However, size isn’t everything. The Nikon’s body shape feels a bit more sculpted and ready for a firm grip compared to the blockier, more minimalist design of the Olympus. This can translate to more secure handling when shooting at longer focal lengths where stability is crucial.

From the top view, Nikon clearly provides more tactile controls - a dedicated zoom lever surrounding the shutter button, clearly labeled mode dial, and well-placed exposure compensation button. The Olympus has fewer physical controls with a small zoom lever but no dedicated modes dial, relying more on menu navigation. The Nikon’s control scheme lends itself better to quick adjustments in dynamic shooting environments - a decisive advantage once you start exploring manual exposure modes or rapid shooting.

Summary: If portability is your absolute priority, the Olympus SZ-15 nudges ahead. But for photographers who appreciate ergonomic refinement and a more responsive control layout, the Nikon A900 stands out as the better-designed tool.

Sensor Technology and Image Quality: Under the Hood

Both cameras share the same sensor size, a classic 1/2.3-inch format measuring approximately 6.17x4.55 mm with an area of 28.07 mm². This is standard for compact superzoom cameras but imposes inherent limitations on image quality compared to larger APS-C or full-frame sensors.

The Nikon A900 packs a 20-megapixel backside-illuminated (BSI) CMOS sensor, which is a slight technological edge as BSI sensors generally perform better in low light due to more efficient light gathering. The Olympus SZ-15 features an older 16-megapixel CCD sensor, which tends to be less efficient in noise management and dynamic range.

Resolution-wise, the Nikon records images at 5184x3888 pixels, while Olympus maxes at 4608x3456 pixels in a slightly wider 4:3 aspect ratio, but also offers 1:1, 3:2, and 16:9 options - giving a bit more framing flexibility if you prefer square or wide formats.

Low-light and high ISO sensitivity:
Both cameras top out at ISO 3200, but here the Nikon’s sensor technology combined with its image processor surprisingly maintains usable image quality at ISO 800 and even ISO 1600, retaining decent color fidelity and reduced noise. The Olympus SZ-15’s CCD sensor struggles under the same conditions, producing noticeably more grain and diminished color accuracy.

Dynamic range is modest on both - a common constraint with small sensors - though Nikon’s BSI sensor again pulls ahead just slightly, delivering more retention of highlight details in tricky lighting.

Ultimately, if image quality - especially in varied lighting - is your yardstick, the Nikon A900 is the clear winner in this pairing.

Autofocus, Lens Performance, and Zoom Versatility

With superzoom cameras, one of the most attractive features is an extended zoom range combining landscape capability and reach for wildlife or travel. Both cameras deliver impressive focal length coverage with distinct characteristics.

• Nikon Coolpix A900: 24–840mm equivalent focal range (35x zoom) with maximum apertures of f/3.4 at wide-angle and f/6.9 at telephoto.
• Olympus SZ-15: 23–483mm equivalent focal range (21x zoom) with brighter f/2.8–f/5.9 maximum apertures.

From a practical viewpoint, Nikon’s extended zoom range best serves those who want to get ultra-close without carrying heavy telephoto lenses - ideal for wildlife aficionados capturing birds or distant subjects. Olympus’s brighter maximum aperture at the wide end is better for indoor and low-light shooting but loses telephoto reach.

Macro focus distance:
Nikon offers a startling close-up focus at 1 cm, allowing fine macro shots with a dramatic perspective. Olympus starts at 5 cm, respectable but less versatile for tight macro details.

Both cameras use contrast-detection autofocus systems; however, their implementation differs:

• Nikon A900 supports continuous autofocus and tracking AF, making it more adept at securing sharp images of moving targets (think kids at play or active wildlife).
• Olympus SZ-15 focuses slower and only offers single AF in practice, lacking continuous AF which hampers capturing fast-moving subjects.

The slower shutter speed limit on the Olympus (max 1/2000s vs Nikon’s 1/4000s) also puts constraints on freezing very rapid action.

Continuous shooting:
Olympus boasts 10 fps burst, which seems impressive, but the lack of continuous autofocus during burst shooting limits its practical utility. Nikon’s 7 fps with continuous AF tracking is more effective for real-life dynamic photography.

Image stabilization:
Both implement optical image stabilization - critical given their long zooms - but Nikon’s newer system felt more effective in hand-holding telephoto shots in my testing, reducing blur notably at the far reach.

LCD Screens and Viewfinders: What You See is What You Get

Neither camera offers a built-in electronic viewfinder, which is usual for this class, so the LCD screens become the primary composing tool.

The Nikon A900 offers a tilting 3-inch screen with 921k-dot resolution, providing excellent brightness and color accuracy. The tilt function is especially handy for low-angle or overhead shooting - used often in street and travel photography. The Olympus SZ-15’s fixed 3-inch LCD delivers only moderate 460k-dot resolution, resulting in less crisp and less vibrant live image previews.

In bright daylight, the Nikon’s screen remained far more visible and responsive - an important advantage for outdoor travel or nature photography where glare is a recurring challenge.

Neither camera is touch-enabled, which might disappoint modern users accustomed to touchscreen control. Menus on both are straightforward but somewhat dated; Nikon’s interface feels more logical, reflecting a more recent design ethos.

Video: Capabilities and Limitations at a Glance

While these cameras are primarily photo-centric, video functionality increasingly influences purchasing decisions.

• Nikon Coolpix A900: Offers 4K UHD recording at 30p/25p and Full HD up to 60p/50p.
• Olympus SZ-15: Limited to Full HD 1080p at 30 fps maximum.

For those prioritizing video, Nikon’s 4K support is a mark of progress. Footage quality is respectable, and built-in optical stabilization smooths handheld clips noticeably. However, neither has microphone or headphone ports, which constrains audio control; users looking to create polished video productions would want to look elsewhere.

The Olympus SZ-15 delivers no 4K recording and relatively basic video codecs (AVI MPEG4, Motion JPEG), which feel outdated by today’s standards.

Neither camera supports advanced video features like slow-motion Full HD at high frame rates or clean HDMI output. They’re best suited to casual videography rather than semi-professional use.

Battery Life and Storage: Staying Power in the Field

Field durability can often disrupt shooting plans, so battery life and storage flexibility matter.

The Nikon A900 uses an EN-EL12 battery model, delivering about 300 shots per charge per CIPA measurement. In my prolonged outdoor testing scenarios, this translated to a full day's casual shooting, though heavy video use reduced it considerably.

The Olympus SZ-15’s official battery life is unlisted, but practical tests suggest similar endurance. It uses the SLB-10A, a slightly smaller capacity battery that will need topping up for longer outings.

Both cameras accommodate a single SD/SDHC/SDXC card, which is standard, but Nikon supports faster UHS-I speeds for rapid file writing - helping manage larger 4K video files and continuous bursts.

Build Quality and Weather Sealing

Neither camera boasts weather sealing, splash-proofing, or rugged construction - expected given their value-conscious design and compactness. Users shooting in challenging weather should protect these cameras to avoid moisture or dust ingress.

The Nikon’s slightly heftier build imparts a sense of solidity, while the Olympus feels lighter and plasticky but standard for consumer compacts.

Connectivity and Wireless Features: Modern Conveniences

Wireless features have become a basic expectation. Nikon leads here with built-in Wi-Fi, Bluetooth, and NFC, enabling quick wireless image transfers and remote control via smartphone apps. The Olympus SZ-15 offers basic built-in Wi-Fi but lacks Bluetooth or NFC. Its connectivity options lag behind by several years.

Both feature micro-HDMI and USB 2.0 ports, but neither supports USB charging, a downside for travel photography where convenient power options are welcome.

Putting It All Together: Performance Scores and Genre Suitability

While neither camera has DXOmark scores, careful hands-on metrics and cumulative testing give us a clear comparative edge:

• The Nikon A900 scores higher across image quality, autofocus responsiveness, user interface, video options, and connectivity.
• The Olympus SZ-15 scores better on burst rate but falls short in core image quality and low light.

Let’s contextualize the cameras by typical photography styles:

• Portraits: Nikon better captures skin tones and supports face detection autofocus. The Olympus, although having a faster aperture at wide angle, lacks continuous AF, limiting precision with moving subjects.
• Landscape: Nikon’s higher resolution and slightly better dynamic range make it more suitable.
• Wildlife: Nikon’s 35x zoom and AF tracking edge Olympus’s 21x zoom and single autofocus mode, critical for fast, distant subjects.
