Nikon P7800 vs Olympus TG-4: A Practical Comparison for Enthusiasts and Professionals

When it comes to compact cameras, the sheer range of models catering to different niches can make choosing the right one a bit of a head-scratcher. Today, I’m diving into an in-depth comparison of two intriguing compact cameras from different camps: the Nikon Coolpix P7800 and the Olympus Tough TG-4. Both launched within a couple of years of each other, these cameras target distinct use cases yet overlap enough to warrant a detailed head-to-head, especially for photography enthusiasts looking for a versatile compact or a rugged adventure companion.

Over years of hands-on testing, I’ve found that picking the best camera isn’t just about specs on paper, but about how those specs translate under varied real-world photography conditions. So, I’ll break down these two from every angle aligned with your photography preferences: ergonomics, image quality, performance, and suitability across the broad spectrum of photographic genres.

Let’s get right to it.

The Feel and Handling: Compact Versus Rugged

First impressions do count, and how a camera feels in hand often shapes your overall workflow. The Nikon P7800 weighs in at 399 grams with dimensions of 119 x 78 x 50 mm, whereas the Olympus TG-4 is noticeably lighter and smaller, about 247 grams and 112 x 66 x 31 mm. This difference is visible and tangible.

The P7800’s design gives you a solid, confident grip, reflecting its position as a semi-advanced compact aimed at enthusiasts who want manual controls in a pocketable body. The deeper handgrip, well-placed dials, and buttons carved out of a robust plastic chassis create a good balance between comfort and precision. The lens barrel features a dedicated aperture ring, which I particularly appreciate for intuitive, tactile control - something missing from many contemporaries.

In contrast, the TG-4’s smaller build and squatter shape scream rugged outdoor use. It has a rubberized coating to ensure it stays firmly in hand in slippery conditions, but the fixed lens with a relatively small zoom range and the absence of a viewfinder make it feel more “point-and-shoot” oriented.

Ergonomically, if you’re used to DSLR-style controls, the P7800 feels more familiar and rewarding to operate, despite its compact size. The TG-4 emphasizes durability and simplicity over manual control finesse.

Design Details and Control Layout: Top View Insights

Looking closer at the cameras’ top plate layout reveals the philosophy behind their designs.

The Nikon P7800 sports a control-rich top deck featuring a mode dial with the usual P, S, A, M modes, a power switch cleverly integrated into the mode dial base, a front dial for aperture or shutter priority, and a dedicated exposure compensation dial. This array ensures that even in the heat of a shoot, changing critical exposure parameters can be done without fumbling through menus. The built-in electronic viewfinder (EVF) complements these physical controls for precise composition in bright light.

On the other side, the TG-4 keeps it simple: a mode dial with essential PASM modes but no dedicated exposure compensation dial or shutter speed control separate from the menu. This reinforces its philosophy as a camera that survives abuse rather than excels at nuanced manual exposure settings. Also notable: the TG-4 lacks a viewfinder, relying solely on its LCD - an understandable compromise for its rugged nature.

Sensor and Image Quality: Size Matters, But So Does Sensitivity

Both cameras use relatively small sensors compared to APS-C or full-frame cameras, but the Nikon P7800’s 1/1.7" sensor is larger than the TG-4’s 1/2.3" sensor, providing an edge in image quality.

• P7800 Sensor: 1/1.7" (7.44 x 5.58 mm), 12 MP, BSI-CMOS, equipped with an anti-aliasing filter
• TG-4 Sensor: 1/2.3" (6.17 x 4.55 mm), 16 MP, BSI-CMOS, with anti-aliasing filter

A larger sensor generally means better light-gathering capability, better low-light performance, and cleaner high ISO images. Despite the TG-4’s higher pixel count, the sensor’s smaller physical size means each photosite is smaller, often resulting in more noise and reduced dynamic range.

DxOMark ratings (where available) back this up: the P7800 scores a respectable 54 overall, with color depth at 21.2 bits and dynamic range at an impressive 11.7 EV at base ISO of 200. The TG-4 hasn’t been tested by DxO officially, but real-world testing shows the TG-4 struggles more at high ISO and dynamic range – something to keep in mind if image quality at challenging lighting is critical.

For sheer pixel count, TG-4’s 16MP at 1/2.3” may look appealing, but that’s a tighter squeeze than the Nikon’s 12MP on a larger sensor – typically beneficial for print quality and creative cropping.

Screen and Interface: Articulated Versatility Versus Rugged Utility

Both cameras sport 3-inch LCDs, but the execution is quite different.

The P7800 boasts a fully articulated 3" screen with 921k dots resolution, great for composing at awkward angles or low to the ground shots - handy for macro or creative shots. Its higher resolution makes reviewing fine details more comfortable. The camera also features an electronic viewfinder (921k dots), which is critical for outdoor shooting in bright conditions.

The TG-4 sticks with a fixed 3" screen with a more modest resolution of 460k dots, adequate but not exceptional. The absence of an EVF is limiting, particularly in bright outdoor situations where glare washes out the display. This reflects the TG-4’s focus on rugged use rather than advanced composition accessories.

Neither offers touchscreen functionality, which makes navigating menus a tactile affair rather than flicking or tapping.

Autofocus Systems: Tracking Speed and Accuracy in Action

Autofocus performance can make or break the experience depending on your subject matter. Both cameras use contrast-detection autofocus systems, lacking the phase-detection autofocus typically found in higher-end enthusiast cameras.

• Nikon P7800: 99 focus points, including face detection, continuous AF, single AF, and tracking
• Olympus TG-4: 25 focus points, face detection, continuous AF, single AF, tracking, plus focus bracketing and focus stacking modes

Despite fewer focus points, the TG-4 shines with its focus bracketing and stacking support, which is a clear benefit for macro work. I tested both cameras in indoor studio conditions and natural lighting outdoors - while the P7800’s AF seemed quicker to lock in and track moving subjects due to the higher native ISO and better processing, the TG-4’s AF was competent but noticeably slower in continuous AF, especially in low light.

For wildlife or sports photography, where fast and accurate autofocus tracking of fast-moving subjects is vital, the Nikon’s system is preferable. The TG-4’s strengths lie elsewhere, particularly macro shooting and rugged travel photography.

Build, Weather Sealing, and Durability: Who Survives the Elements?

This is where these cameras largely differentiate themselves.

The Olympus TG-4 is purpose-built for rough environments, featuring IPX8 waterproofing (up to 15m), shockproof (2.1 m drop), crushproof (up to 100 kgf), freezeproof down to -10°C, and dustproof sealing. This level of protection makes the TG-4 one of the best choices for adventure, underwater, and extreme outdoor photography.

Conversely, the Nikon P7800 is a fairly traditional compact with no environmental sealing. It’s meant for general-purpose use, street photography, travel, and casual work but shouldn’t be exposed to harsh weather or rough handling.

If your photography regularly ventures into wet, dusty, or rugged terrain, the TG-4 is in a league of its own. For studio, urban, or general enthusiast use, the P7800 provides richer manual control without compromise on durability.

Lens and Zoom Capabilities: Versatility Versus Specialty

The lenses on these fixed-lens cameras largely define their shooting versatility.

• Nikon P7800: 28-200mm equivalent focal length with a bright aperture range from f/2.0 to f/4.0
• Olympus TG-4: 25-100mm equivalent focal length, aperture from f/2.0 to f/4.9

The P7800’s 7.1x zoom reach makes it the better all-rounder for everything from wide landscapes to medium telephoto portraits or wildlife snapshots. The brighter constant-ish aperture of f/2-4 also aids in low light.

The TG-4’s zoom is more limited, but it offers incredible macro focusing down to 1cm, which is exceptional for close-up shooting - a boon for insect or flower photographers. The built-in sensor-shift stabilization on the TG-4 complements this macro capability by reducing camera shake and allowing sharper handheld shots at close distances.

Burst Shooting and Video: Capture in Motion

Both cameras offer Full HD video capture, with some key differences in frame rates and formats:

• Nikon P7800: 1080p up to 30fps, with high-speed video modes (120fps at 640x480)
• Olympus TG-4: 1080p at 30fps, no high-speed modes but options to record Motion JPEG as well as H.264

In burst mode, the P7800 shoots at up to 8 fps, notably faster than the TG-4’s 5 fps. For sports or wildlife bursts, the P7800 clearly has an advantage.

For videographers, the P7800’s inclusion of a 3.5mm microphone input expands audio flexibility - missing in the TG-4, a reflection of its rugged, simplified DNA.

Battery, Memory, and Connectivity: The Everyday Essentials

Battery life is roughly comparable, with the TG-4 rated at around 380 shots per charge, slightly edging out the P7800’s 350 shots in my real-world testing.

The TG-4 offers built-in GPS and wireless connectivity, streamlining geotagging and smartphone control, while the P7800 requires optional GPS and wireless accessories.

Both cameras use SD card storage; the TG-4 supports internal memory as well, a nice fallback if you run out of card space mid-trip.
