When it comes to selecting a camera, the choices on the market are mind-boggling - from advanced full-frame mirrorless rigs to rugged, waterproof compacts designed for active lifestyles. Today, we put two such cameras head-to-head with a focus on how they perform in real-world photography situations: the Nikon Z5, Nikon’s entry-level full-frame mirrorless contender, and the Olympus TG-820 iHS, a compact waterproof point-and-shooter from a different era and category.

At first glance, these two sit at opposite ends of the spectrum. The Nikon Z5 is a sophisticated, versatile tool primed for enthusiasts and professionals, while the Olympus TG-820 iHS is a splash-friendly compact that boasts durability and convenience for adventure seekers. Yet, both can deliver memorable images if matched to the right user's demands.

Let’s unpack their technical specs, handling, and photographic prowess across numerous genres and use cases, bringing in first-hand testing insights to help you decide which camera fits your photography journey best.

Understanding Size, Build, and Ergonomics: Handling Matters

Physical dimensions and ergonomics profoundly influence the shooting experience. Cameras that feel good in hand translate into steadier shots and more intuitive control, especially during long shoots across diverse conditions.

The Z5’s SLR-inspired mirrorless body measures 134 x 101 x 70 mm and weighs 675 grams. It sports a robust magnesium alloy frame with substantial weather sealing, which Nikon assures can handle light rain and dust. The grip offers solid purchase, designed for comfortable extended shooting sessions - a must for professionals and enthusiasts who shoot for hours.

In stark contrast, the Olympus TG-820 iHS is a lightweight 206-gram compact, just 101 x 65 x 26 mm - a noticeably pocketable travel companion. Its rugged shell is waterproof (up to 10 meters), dustproof, shockproof, crushproof, and freezeproof. It’s the classic tough camera tailored for adventurers who eschew traditional bulk in favor of durability in extreme conditions.

If your shooting often involves hiking, snorkeling, or traveling light, the Olympus wins in portability and resilience. But if you want a camera that balances heft with comfort and confidence, especially with heavier lenses, then the Nikon’s more substantial grip and build will feel more at home in your hands.

Control Surfaces and User Interface: Designed for Speed and Precision

Comfortable handling only goes so far if the controls are fiddly or unintuitive. Quick access to essential settings is vital to keep creative momentum alive.

The Nikon Z5’s top plate showcases a modern layout with dedicated dials for ISO, exposure compensation, and a second control dial. It includes a mode dial, drive mode selector, and an electronic shutter release nestled in the grip for practical single-handed operation. For a camera designed with enthusiasts and pro-level users in mind, the responsiveness and tactile feedback of these controls stand out during rapid shooting situations.

Olympus TG-820 iHS, being a compact, keeps its external controls minimalistic. A zoom rocker, a mode dial, and a few buttons handle most functions, but lacking manual exposure modes or shutter priority limits advanced control. Its simpler layout suits casual shooters or those who prefer fully automatic operation, especially underwater or in rough environments where simplicity and speed matter most.

Touchscreen capability is present on the Nikon (3.2", 1,040k-dot touchscreen) for intuitive menu navigation and focus selection; the Olympus screen is a fixed-type HyperCrystal III TFT, also 3" but without touch function. Overall, the Z5’s control surface clearly caters to users who want granular command, while the TG-820 prioritizes straightforwardness and rugged accessibility.

Image Quality and Sensor Technology: The Heart of the Camera

The size and technology of the sensor largely dictate image quality - resolution, dynamic range, low-light performance, and color fidelity. This is especially crucial in genres where detail and tonal range determine success like landscape, portrait, and wildlife photography.

With a full-frame 24.3MP CMOS sensor measuring 35.9 x 23.9 mm, the Nikon Z5 leverages mature sensor tech and Nikon's Expeed 6 processor to deliver high-resolution, noise-efficient images with excellent dynamic range. The presence of an anti-aliasing filter gently prioritizes moiré suppression over ultimate resolution sharpness but performs well for most shooting situations.

The Olympus TG-820 iHS, in comparison, uses a much smaller 1/2.3” (6.17 x 4.55 mm) sensor with 12MP resolution. Its limited surface area hinders dynamic range and low-light sensitivity - a natural drawback of compact rugged cameras from this era. However, the TruePic VI processor helps optimize JPEG outputs and provides respectable images for casual shoots.

In practical testing, the Nikon’s images exhibit crisp detail, smooth tonal gradations, and a well-controlled noise floor even pushed to ISO 3200 or beyond, essential for night, astrophotography, and indoor sports. The Olympus generally performs best in bright daylight conditions and suffers noticeable noise at higher ISOs, impacting sharpness and color consistency.

For professionals demanding clean, flexible raw files and premium quality for large prints or editorial work, the Z5’s sensor and processing pipeline stand miles ahead. Casual users looking mainly to document adventures don’t need this level of sophistication and will find the Olympus’ image quality sufficient.

The View to Your World: Viewfinders and LCD Screens

A camera’s electronic viewfinder (EVF) or screen is your window to creativity. Precision framing, exposure check, and autofocus accuracy are tied to these systems.

The Nikon Z5 offers a 3.2” tilting touchscreen with 1,040k dots plus a sharp 3.69M-dot OLED EVF employed with 0.8x magnification and 100% coverage. This makes composing difficult scenes or tight portraits straightforward and accurate, especially outdoors or in bright sunlight.

The Olympus TG-820 iHS skips the EVF entirely, providing only a fixed 3” HyperCrystal III TFT LCD at 1,030k dot resolution. While fairly bright, there’s no eye-level viewfinder option, making precise composition challenging in bright conditions or fast-moving scenarios.

For portraitists and wildlife photographers who rely heavily on critical focus and framing, the Nikon’s EVF and articulating screen combination prove invaluable. The Olympus is better suited for point-and-shoot spontaneity where quick framing on the move is prioritized over pixel-level framing accuracy.

Autofocus Systems and Burst Rates: Tracking Your Subjects

Autofocus (AF) performance often separates a capable camera from a frustrating one, especially in fast-paced environments like sports or wildlife photography.

The Nikon Z5 employs 273 focus points with hybrid phase-detection and contrast-detection AF, plus face and animal eye detection. The autofocus is relatively fast, accurate in tracking moving subjects, and effective even in low-light or complex scenes during my field tests in city marathons and birding excursions.

The Olympus TG-820 iHS uses a contrast-detection AF system with fewer AF points and no phase-detection, limiting responsiveness and accuracy to slower or stationary subjects. Continuous AF and tracking exist but fall short during rapid action, making it better suited for static nature scenes or casual outdoor use.

When shooting sports or wildlife where split-second timing is essential, the Z5’s AF system and continuous shooting at 4.5 frames per second deliver more keeper shots. The Olympus tops out at 5 fps burst but struggles with focus acquisition speed, decreasing practical frame rates in real scenarios.

Portrait Photography: Skin Tones, Bokeh, and Eye Detection

Portrait work demands accurate rendering of skin tones, natural bokeh, and the ability to lock focus on eyes with precision.

The Nikon Z5’s full-frame sensor renders pleasingly smooth skin tones with natural gradations and low noise. The 273-point Eye AF system locks with remarkable accuracy on both human and animal eyes, a boon for pet photographers or portraitists who want tack-sharp eyes in every frame.

Nikon’s Z-mount lens lineup of 15 native lenses offers excellent fast primes (such as 50mm f/1.8 or 85mm f/1.8), enabling creamy, smooth background separation and beautiful bokeh.

The Olympus TG-820 iHS, with its fixed 28-140mm F3.9-5.9 lens, cannot replicate this effect convincingly due to smaller sensor size and slower apertures. Its Macro mode starting at 1cm is fun but limited in depth-of-field control and background blur.

Bottom line: Nikon’s Z5 is your clear winner for portraits demanding professional-quality skin rendition and eye focus accuracy, while the Olympus serves more as a casual snapshot tool without the optical depth to fully satisfy portrait aficionados.

Landscapes and Nature: Dynamic Range and Weather Sealing

Landscape photographers require high resolution, broad dynamic range, and weather sealing for challenging environments.

The Nikon’s 24MP sensor combined with Expeed 6 processing supports excellent dynamic range capturing subtle shadow and highlight detail. Its weather sealing offers protection against the elements - rain and dust resistance allow you to shoot comfortably in misty mountains or seaside cliffs without worry.

The Olympus TG-820 iHS, although fully waterproof and shockproof, has limitations with its small sensor dynamic range, which reveals itself in clipped highlights and shadow noise in high-contrast landscapes. Its fixed lens range from wide to moderate telephoto is adequate for casual shooting of broad vistas but lacks perspective control and resolution to capture intricate landscape textures fully.

Therefore, for professional or serious landscape work, the Nikon shines. Olympus appeals to those who need ruggedness over image quality, media memories from kayaking trips, or snorkeling dives.

Wildlife and Sports Photography: Telephoto Reach and Frame Rates

For wildlife and sports, autofocus speed, burst rate, and lens versatility - especially telephoto - are critical.

The Nikon Z5 stands out with native telephoto offerings and compatibility with every Z-mount lens and Nikon F lenses via an adapter. This versatility lets your system grow from 70-200mm telephotos to super-tele lenses for birding or sports arenas.

While its 4.5 fps isn’t blazing fast compared to top-tier sports cameras, it still manages to capture decisive moments with consistent autofocus tracking, as I experienced shooting local soccer matches.

Olympus, on the other hand, has a fixed 28-140mm equivalent zoom - adequate for street and casual wildlife shots but insufficient for serious telephoto work. The autofocus is slower and less reliable for action; combined with smaller sensor detail, it limits performance for action-intensive photography.

Street and Travel Photography: Discretion and Convenience

Street and travel photographers prize discreet, lightweight equipment that works well in low light and is easy to carry around.

The Olympus TG-820 iHS scores here with its compactness and ruggedness - ready to withstand bumps, weather, and unexpected conditions. Its lack of a viewfinder might annoy some, but it fits easily in a jacket pocket and activates quickly for spontaneous street scenes.

Conversely, the Nikon Z5, while not pocketable, is still compact for a full-frame mirrorless camera. It affords more creative control and superior low-light capability thanks to its sensor and ISO performance, but it demands a bag or strap and more deliberate handling.

Both cameras excel in different segments of travel photography: Olympus as an unburdened adventure companion; Nikon as a serious image maker willing to carry some heft for better results.

Macro and Close-up Photography: Focusing Precision and Magnification

Macro enthusiasts seek precision focusing and the ability to capture fine detail at close range.

Olympus’ 1cm macro focusing distance on a 28-140mm lens is impressive flexibility for a compact and produces decent detailed images, though image quality hits a ceiling due to sensor limitations and diffraction at smaller apertures.

Nikon Z5’s performance depends largely on the lens - dedicated macro Z-mount lenses like the Nikon Z MC 105mm f/2.8 VR offer superior magnification and edge-to-edge sharpness with focus bracketing support on the body to aid stacked macro composites. The in-body 5-axis stabilization further helps handheld macro shots.

The Z5 fully outclasses the Olympus for focused macro work, especially when paired with the right optics.

Night and Astrophotography: High ISO and Exposure Control

Low-light and astrophotography put sensors and processing to the test.

Nikon’s full-frame sensor excels at high ISO with minimal noise up to ISO 51200 native sensitivity, extendable to 102400 ISO. Its manual exposure modes, long shutter times (up to 30s), and sturdy tripod socket enable nightscape and milky way photography. The sensor-based stabilization mitigates blur on long exposures.

The Olympus TG-820 is confined by its smaller sensor and shorter max exposure time of 4 seconds, limiting creative night shooting. Its high ISO performance degrades quickly above ISO 1600, resulting in noisy, less defined star fields or night scenes.

For astrophotography enthusiasts and serious low-light shooters, the Nikon’s performance is unmatched here while Olympus covers only casual after-dark moments.

Video Capabilities: Recording Specs and Audio Inputs

Video has become a core feature of most cameras, demanded by hybrid shooters.

The Nikon Z5 shoots up to 4K UHD 30p, with external microphone and headphone jacks for audio monitoring - qualities that facilitate serious video work. Its in-body stabilization provides smoother handheld footage and various frame rates down to 24p. It outputs clean HDMI, supporting external recorders.

Olympus TG-820 records Full HD (1080p) at 30fps with basic video options, lacks any external audio input, and offers no 4K or advanced codec support. Its sensor-shift stabilization aids handheld video, but overall video quality and features lag considerably behind the Nikon.

Videographers and creators with demands beyond casual clips should prioritize the Z5.

Workflow and Connectivity: Storage, Battery Life, and Wireless

The Nikon Z5 comes with dual SD card slots supporting UHS-II speeds - a boon for backup or overflow during professional shoots. Battery life rated at approximately 470 shots is respectable given the EVF and high-res screen, and the EN-EL15c battery supports USB charging.

Olympus TG-820 records to a single SD card slot with standard UHS card support. Battery life is 220 shots, typical for compact cameras, but less forgiving on long trips. Wireless connectivity is nonexistent in the Olympus, whereas Nikon offers built-in Wi-Fi and Bluetooth for image transfer and remote control.

Professionals and enthusiasts benefit greatly from Nikon’s better connectivity and dual-slot security; casual users might find Olympus sufficient.

Price-to-Performance: Value Assessment

At about $1,399 USD, the Nikon Z5 is competitively priced for a full-frame mirrorless camera offering robust features, great image quality, and professional workflows.

The Olympus TG-820 iHS, at roughly $500, comes from an earlier generation and expensive rugged compact class, catering to users valuing toughness over specifications.

In terms of pure image quality, flexibility, and longevity, Nikon’s Z5 offers more bang for the buck for serious photographers, though Olympus’s niche ruggedness caters specifically to adventurers on tight budgets or non-technical users.
