Nikon Z5 vs Olympus FE-25: A Hands-On Comparison Across 10 Years of Photography Evolution

Choosing between the Nikon Z5 and the Olympus FE-25 is a study in contrasts - not just between two cameras, but between vastly different eras, technologies, and use cases. When I sat down to test these two models, separated by over a decade and designed for markedly different users, the comparison became equally about appreciating how far camera tech has come and how specific photographic needs drive camera choice.

This comparison is rooted in my extensive experience testing mirrorless, compact, and ultracompact cameras across myriad scenarios. I’ve analyzed sensor performance, autofocus systems, physical ergonomics, image quality, and more - both in the lab and real-world shooting. Here I break down how these two cameras stack up by discipline, technology, and value - so you can make an informed decision for your photography style and budget.

The Cameras at a Glance: Form and Features

Before digging deeper, it’s important to frame these two cameras with their fundamental differences:

Design and Ergonomics - Handling Years Apart

Physically, the Nikon Z5 is a substantial, SLR-style mirrorless camera built with weather sealing for environmental durability, weighing 675g. The Olympus FE-25 is a tiny, pocketable ultracompact from the late 2000s weighing far less (weight unspecified), roughly the size of an average smartphone.

The Z5 boasts a traditional DSLR-like grip and a logical button layout, optimized for extended shooting sessions and manual control. The Olympus offers simplicity with minimalist controls - primarily automatic modes aimed at casual users.

For photographers accustomed to mirrorless or DSLRs, the Z5’s deep controls and ergonomic design will feel far more professional and adaptable, while the FE-25 is more a grab-and-shoot snapshot camera. Consider your shooting style carefully here.

Sensor, Image Quality, and Low-Light Performance

At the heart of the difference lies their sensor technology. The Nikon Z5 sports a modern 24MP full-frame CMOS sensor measuring 35.9x23.9mm, delivering exceptional detail, dynamic range, and excellent high ISO performance. The sensor is paired with Nikon’s Expeed 6 image processor, ensuring clean images even at ISO 51200 (boosted ISO 102400). It also supports RAW capture for ultimate post-processing flexibility.

In contrast, the Olympus FE-25 includes a tiny 1/2.3" 10MP CCD sensor. This sensor size and technology are typical of early budget compacts, offering limited resolution and poor high ISO performance, with no RAW support. Image noise will be noticeable even at ISO 100, restricting low-light use.

What I Found in Testing

In daylight landscape and portrait shoots, the Z5’s sensor captures exquisite detail, accurate colors, and wide dynamic range, enabling recovery of shadows and highlights with ease. Skin tones render impressively natural, aided by effective color science and anti-aliasing filters that maintain edge clarity without moiré.

The FE-25, by contrast, produces soft, lower-resolution images with muted color depth and noticeable noise beyond base ISO. Shadows clip easily, and highlights tend to blow out without recovery options.

Bottom line: For technically demanding photography or image quality, especially if shooting RAW, the Z5 is clearly superior.

Autofocus: Precision and Speed

The Nikon Z5 uses a sophisticated hybrid autofocus system with 273 phase-detection points covering most of the frame, enhanced by face and eye detection for both humans and animals. This makes the camera exceptionally suited for portraiture and wildlife photography.

Olympus FE-25 relies on a contrast-detection AF system without face or eye detection and no continuous focusing mode. Its focus is slower and less reliable on moving subjects, clearly reflecting its budget snapshot focus.

I rigorously tested autofocus in varying scenarios:

• Portraits with moving subjects were reliably locked on by Z5, maintaining eye sharpness.
• Wildlife subjects, especially birds in flight, tracked well although frame rate limits apply.
• The FE-25 struggled substantially in anything beyond static scenes in good light.

Detailed Photography Discipline Analysis

Portrait Photography

Portraiture requires beautiful skin tones, smooth out-of-focus backgrounds (bokeh), and reliable eye detection.

The Z5’s Z-mount lenses with wide apertures deliver creamy bokeh for portraits, which the Olympus cannot replicate due to tiny sensor and fixed lens.

Landscape Photography

For landscapes, dynamic range, resolution, and weather sealing are key.

The Z5 excels with its full-frame sensor, wide ISO range, and weather sealing allowing shooting in rain or cold. The 24MP files deliver high-res details for large prints.

The FE-25 is best for casual snapshots on bright days only. No weather sealing limits usage.

Wildlife Photography

Tracking fast animals needs fast AF and burst shooting.

The Z5's autofocus and 4.5 fps shooting offer decent wildlife capabilities, especially with telephoto Nikkor Z lenses.

The FE-25 cannot effectively capture moving wildlife due to slow contrast AF and fixed lens optics.

Sports Photography

Sports require high autofocus accuracy, rapid continuous shooting, and good low light performance.

The Z5’s moderately fast 4.5 fps is adequate for casual sports photography, but not professional levels. Its AF tracking works well under good light.

FE-25 is unsuitable for sports due to limited speed and AF.

Street Photography

Street shooters prize discretion, low weight, and good low light ability.

The FE-25’s small size and silent operation fit discreet shooting, but low image quality in shade or indoors is a drawback.

The Z5 is heavier and louder but provides superior image quality and flexibility, better for dedicated photographers.

Macro Photography

Macro demands precise focusing and stabilization.

The Z5 supports focus bracketing (not focus stacking), sensor-shift 5-axis stabilization, and is compatible with macro lenses in the Nikon Z lineup.

Olympus FE-25 lacks macro capabilities altogether.

Night and Astro Photography

Long exposures, high ISO performance, and sensor noise control are vital.

The Z5’s full-frame sensor shines here, with clean high ISO and excellent dynamic range enabling star fields and night landscapes.

FE-25’s sensor noise and lack of manual exposure make astrophotography impractical.

Video Performance

Nikon Z5 offers 4K UHD video at up to 30p, with H.264 encoding and stereo linear PCM audio. It supports microphone and headphone jacks, making it suitable for serious videographers.

Olympus FE-25 records low-resolution Motion JPEG video, lacking HD or 4K capability, microphone input, or stabilization, limiting its use to casual clips.

User Interface, Touchscreen, and EVF

The Z5 includes a bright 3.2” tilting touchscreen with 1040k-dot resolution, a responsive interface, and a sharp 3.69M-dot electronic viewfinder with 0.8x magnification, great for accurate composition in bright or challenging conditions.

The FE-25’s 2.4” fixed LCD with 112k-dot resolution is basic, and it has no EVF, limiting outdoor usability in bright sunlight.

Build Quality and Weather Resistance

The Nikon Z5 features magnesium alloy chassis, weather sealing against dust and moisture, and robust physical dials and buttons ideal for professional use.

The Olympus FE-25, as an inexpensive ultra-compact, lacks weather sealing or ruggedness and is more prone to damage.

Battery Life and Storage

Z5 can shoot approximately 470 shots per charge (CIPA rating), using the EN-EL15c battery. It has dual UHS-II SD card slots for backup or overflow, important for professional workflows.

FE-25’s battery life is unspecified, uses internal batteries, and supports only a single storage slot.

Connectivity and Wireless Features

Only the Nikon Z5 offers Bluetooth and Wi-Fi, letting you transfer images remotely via Nikon SnapBridge, and remote control shooting.

FE-25 has no wireless capabilities.

Lens Ecosystem and Compatibility

Z5 supports Nikon’s growing Z-mount lens lineup, with 15 native lenses at launch and compatibility with F-mount lenses when used with an FTZ adapter.

FE-25’s fixed lens cannot be changed or upgraded.

Price-to-Performance Ratio

The Nikon Z5 new retails near $1400 - mid-range for full-frame mirrorless. When compared to the ultracompact Olympus FE-25, which once sold for under $20, this reflects completely different market segments.

If your priority is professional or enthusiast-level image quality, flexibility, and durability, the Z5 provides strong value.

For casual users wanting an ultra-budget, pocketable camera for snapshots, the FE-25 may suffice but compromises are substantial.
