Nikon P7800 vs Sony G3: An Expert Comparison of Compact Cameras for Enthusiasts and Professionals

In the realm of small sensor compact cameras, the choice can be surprisingly nuanced. Two intriguing contenders that often surface in discussions are the Nikon Coolpix P7800 and the Sony Cyber-shot DSC-G3. Despite both being compact cameras aimed at enthusiast photographers, they occupy distinct positions in features, image quality, and user experience. Knowing which one suits your needs requires a deep dive into their specifications, real-world performance, and ergonomics - all from a seasoned photographer’s perspective.

Having personally tested both models through rigorous shooting in multiple scenarios, I’ll guide you through a decisive comparison. You’ll find practical insights, hands-on observations, and professional-grade data to help you decide confidently.

Size, Handling, and Ergonomics: The Grip Factor

When assessing compact cameras, size and handling can greatly influence shooting comfort and creativity, especially for long sessions or on the move.

The Nikon P7800 is a notably chunky compact at 119 x 78 x 50 mm and weighing 399g, while the Sony G3 is smaller and lighter at 97 x 59 x 22 mm and just 185g. This difference is palpable in hand-holding and portability.

Nikon P7800 vs Sony G3 size comparison

The Nikon’s ergonomics benefit from a substantial grip, physical dials, and a tactile feel - ideal for photographers who prefer manual controls and want stability without an external grip. Meanwhile, the Sony G3, being slim and lightweight, excels in true pocket portability but sacrifices some of that secure hold.

Top view control layout also underscores their personalities: Nikon’s physical dials for shutter speed, aperture, and exposure compensation make it an enthusiast’s playground; Sony’s more minimal and streamlined layout caters to casual or beginner users.

Weight & Size Heavier, more substantial grip Light, ultra-compact
Control Layout Dedicated dials and buttons Simplified, fewer physical controls
Viewfinder Electronic viewfinder (921k resolution) No viewfinder
Screen Fully articulated 3” screen Fixed 3.5” touchscreen

If you prize tactile control and shooting stability, especially in varied light or faster-paced scenarios, the Nikon shines. For travel or street shooters valuing discretion and lightness - the Sony G3 fits better.

Sensor and Image Quality: The Heart of Photography

Sensor characteristics and image quality potential form the foundation of any camera’s appeal.

Specification Nikon P7800 Sony G3
Sensor Type 1/1.7" BSI-CMOS 1/2.3" CCD
Sensor Dimensions 7.44 x 5.58 mm (41.52 mm²) 6.17 x 4.55 mm (28.07 mm²)

What Does This Mean Practically?

  • The Nikon’s 1/1.7" backside illuminated CMOS sensor delivers superior light collection efficiency and dynamic range. BSI-CMOS sensors generally outperform older CCDs, especially in low light.
  • The Sony G3’s smaller CCD sensor is older technology. While it can produce respectable daylight images, it struggles with noise, dynamic range, and high ISO performance.
  • Nikon’s RAW support opens advanced post-processing flexibility vital for enthusiasts and professionals. Sony compresses to JPEG with no RAW option, limiting creative control.

Image Samples

Quietly, I put both cameras through real-world shooting - landscapes, portraits, indoor events - and here are side-by-side crops at native ISO 320:

The Nikon’s details hold strong, with cleaner shadows and richer colors. The Sony’s images show more pronounced noise and softer details, especially when shadows deepen.

Summary - Image Quality:

  • Nikon P7800 offers a definite technical edge with sensor, ISO range, and RAW for superior image quality and flexibility.
  • Sony G3 remains adequate for casual shooting but is outmatched in dynamic range, noise handling, and resolution.

Autofocus System and Speed: Catch the Action

For subjects anywhere from portraits to wildlife, autofocus (AF) performance is a game changer.

Feature Nikon P7800 Sony G3
AF Type Contrast-detection Contrast-detection
AF Points 99 9
Face Detection Yes No
Continuous AF Yes No
AF Tracking Yes No
Burst Shooting 8 FPS 2 FPS

The Nikon’s 99-point contrast-detection AF allows fast, accurate focusing and tracking, ideal for sports, wildlife, and active street photography. Face detection further helps for portrait work, diligently locking on subjects’ eyes.

The Sony’s sparse 9-point AF system and lack of face detection produce slower focus lock and more missed shots in demanding conditions. With a mere 2 FPS burst, it’s less suited for capturing fast action.

If autofocus responsiveness and tracking are priorities - especially in low light or unpredictable scenes - the Nikon P7800 convincingly outperforms.

Lenses and Optical Performance

Neither camera has interchangeable lenses; both use fixed zoom lenses integral to the body, but their focal ranges and apertures differ significantly:

Feature Nikon P7800 Sony G3
Focal Length 28-200 mm (equivalent) 35-140 mm (equivalent)
Aperture Range f/2.0 - f/4.0 f/3.5 - f/10.0
Macro Focus Range 5 cm Not specified
Image Stabilization Optical (Lens-shift) Optical (Lens-shift)
Built-in Flash Yes (10 m range) Yes (4.3 m range)
External Flash Supported None

The Nikon’s longer reach, faster max aperture (especially at the wide-angle), and closer macro focusing make it a more versatile all-rounder. Wider aperture also aids low-light and shallow depth of field effects in portraiture.

The Sony lens is slower, limiting low-light capability and bokeh control. Its shorter zoom range restricts versatility, but the camera’s overall compactness compensates somewhat for casual use.

Display and User Interface: Shooting Experience

Both cameras carry 3” or larger screens, but key differences affect usability:

Feature Nikon P7800 Sony G3
Screen Size 3” 3.5”
Screen Resolution 921k dots 921k dots
Articulation Fully articulating Fixed
Touchscreen No Yes
EVF Yes, 921k resolution None

Nikon P7800 vs Sony G3 Screen and Viewfinder comparison

The Nikon’s fully articulated screen offers compositional flexibility - great for macro, low-angle, or vlog-style shooting. The electronic viewfinder is a critical advantage under bright sunlight where LCD view is compromised.

Sony’s 3.5” touchscreen makes navigating settings intuitive but lacks articulation or an EVF, meaning framing in bright outdoor conditions can be challenging.

Performance in Different Photography Genres

Let’s evaluate these cameras across various photography niches - from portraits to astrophotography.

Portraits

  • Nikon: Fast f/2 lens for creamy bokeh, face and eye detection autofocus, and accurate skin tone reproduction stand out. Articulated screen helps creative framing.
