Whether you're an experienced professional or a dedicated enthusiast exploring new gear, this hands-on comparison will unravel their strengths, weaknesses, and real-world performance across major photography disciplines.

Handling and Build Quality: When Size and Ergonomics Steer Your Choice

The Panasonic GH5S sports an SLR-styled mirrorless body with solid construction, weather sealing, and a reassuring heft at 660g. Such a design invites confident handling during lengthy shoots. Its dimensions (139x98x87 mm) provide ample grip space, especially important for vertical shooting or telephoto lens usage.

In contrast, the Ricoh CX3 is a compact superzoom camera, weighing just 206g and measuring 102x58x29 mm. It slips effortlessly into your pocket and is perfect for moments when portability and quick grabbing are essential. However, its small body offers limited physical controls and less tactile feedback, making it less ideal for heavy-duty or deliberate shooting sessions.

Key observations:

• GH5S: Robust magnesium alloy body, weather sealing (dustproof and splashproof).
• CX3: Lightweight plastic build, no weather resistance.
• Control layout: GH5S features more physical dials and customizable buttons, improving direct access to settings; CX3 opts for minimalistic controls.

To put it plainly, if you value ergonomics, weather resistance, and physical controls, the GH5S caters to these with its professional design. The CX3 prioritizes portability and simplicity instead.

Control Interfaces: Hands-On, Quick Access vs. Simplicity and Compactness

Looking from above, the GH5S reveals dedicated dials for shutter speed, ISO, exposure compensation, drive modes, and a mode dial, catering to photographers who desire swift operation without diving too deep into menus. Its articulated 3.2" touchscreen LCD with 1,620k-dot resolution complements this, enabling touch focus and easy menu navigation.

The CX3, lacking a top screen or many external controls, relies on a basic fixed display with a lower resolution 3" screen (920k dots). Its limited control set offers some manual focus capability but omits exposure compensation and priority modes, constraining advanced photographers.

If you’re someone who appreciates tactile feedback for shutter speed and ISO changes or wants customizable buttons for fast switching, GH5S outshines the CX3 dramatically in this area.

Viewing and Composing: Electronic Viewfinder Versus Eye-Level Composure

The GH5S provides a tiltable 3.2” fully articulated touchscreen and a high-res 3,680k-dot electronic viewfinder (EVF). In bright sunlight or fast-paced scenarios, the EVF offers a clear composition window with 100% coverage and 0.76x magnification, reducing eye strain and granting precision.

Conversely, the Ricoh CX3 does not have an electronic viewfinder and depends solely on its rear LCD. While good for casual framing, it makes bright outdoor shooting challenging without shading your screen.

Professional note: Having a quality EVF is crucial for wildlife, sports, and street photography, where eye-level shooting and moment-to-moment adaptation are vital. The GH5S’s EVF places it far ahead for such use cases.

Sensor Technology: Four Thirds Powerhouse Against Small Sensor Simplicity

At the heart of any camera’s image quality lies the sensor. The Panasonic GH5S leverages a large Four Thirds (17.3x13 mm) sensor with a 10.2 MP resolution optimized for video and low light, enhanced by Panasonic’s Venus Engine 10 processor. It does not have an anti-aliasing filter, sharpening details noticeably - a deliberate choice for professional video and photography applications.

The Ricoh CX3 features a much smaller 1/2.3" BSI-CMOS sensor (6.17x4.55 mm), 10 MP resolution, and includes an anti-aliasing filter. This sensor size is typical of compact superzoom cameras that prioritize zoom range and pocketability.

What does this mean in practice?

• Dynamic Range and Low Light: The GH5S’s larger sensor captures a broader dynamic range and manages noise better at high ISOs (up to ISO 51,200, expandable to 204,800). The CX3 peaks at ISO 3200, with noticeable noise as sensitivity climbs.
• Resolution: Both deliver around 10 MP; however, GH5S’s pixel quality and low-light performance far surpass the CX3.
• Lens Compatibility: GH5S uses the Micro Four Thirds mount with over 100 lenses available, including professional primes and zooms. CX3 has a fixed 28-300mm equivalent lens (f/3.5-5.6), limiting versatility.

Your choice hinges on how demanding your shooting conditions are. For rich landscapes, portraits with nuanced skin tones, or astrophotography, GH5S’s sensor excels. For casual travel snaps or quick zoom shots, the CX3 suffices.

Autofocus Systems: Precision and Speed Versus Basic Operation

From extensive hands-on testing, autofocus (AF) can make or break the shooting experience.

• Panasonic GH5S:

  • 225 contrast-detection AF points with face detection and continuous AF tracking.
  • Touch AF with selective area modes.
  • Lacks phase-detection AF but compensates with intelligent algorithms for reliable video and stills AF performance.
  • Burst shooting at 12 fps with continuous AF.

• Ricoh CX3:

  • Contrast-detection AF with multi-area selection but limited AF points.
  • No face or tracking AF.
  • Single AF mode only, no continuous AF.
  • No burst shooting.

For wildlife or sports photography, where tracking fast-moving subjects matters, the GH5S offers a clear edge. The CX3’s AF system is too basic for demanding subjects but adequate for static scenes or casual use.
