Panasonic GH2 vs Pentax WS80: An Expert Comparison for Every Photographer’s Journey

Choosing the right camera unlocks your creative potential, but with so many options from vastly different categories, it can be a tough call. Today, we’re diving deep into two very different cameras: the Panasonic Lumix GH2, an advanced mirrorless powerhouse from 2011, and the Pentax Optio WS80, a rugged waterproof compact from 2009. These models target distinctly different users and styles, yet each holds appeal for enthusiasts looking to capture unique moments.

Drawing from extensive testing experience - having put thousands of cameras through rigorous photo and video scenarios - this comparison will help you understand the practical, technical, and creative trade-offs between these models. By the end, you will know which camera aligns best with your style, needs, and budget.

First Look: Design, Size, and Handling

Before firing off shots, handling comfort and portability play significant roles in your shooting experience. How a camera feels in your hands can affect your confidence and creativity.

The Panasonic GH2 sports a classic DSLR-style layout with a solid grip, substantial heft, and a fully articulated touchscreen - a boon for creative angles and video. It feels robust but lightweight enough for all-day use. The larger size accommodates extensive controls and a comfortable handhold.

In contrast, the Pentax WS80 is a tiny, tough compact designed for on-the-go durability. Its slim profile can easily slip into a pocket or glove compartment, perfect for travel or outdoor adventures. Its waterproof and dustproof construction makes it extremely versatile in challenging environments but offers fewer manual controls. The fixed screen means limited flexibility for framing.

You’ll want to weigh the GH2’s advanced ergonomics and control surface against the WS80’s rugged portability depending on your shooting scenarios.

Peek Through the Viewfinder and Screen

Having a clear, responsive display and viewfinder is critical for accurate framing, especially in bright outdoor conditions or during fast-paced photography.

The GH2’s electronic viewfinder offers 100% image coverage with good magnification, making it easier to compose shots even under blazing sunlight or fast action. Its touchscreen LCD articulates and tilts - a major plus when shooting video or awkward angles.

The Pentax opts for no viewfinder, relying entirely on the modest fixed rear LCD. At 230k dots, it’s sufficient for casual compositions but may struggle outdoors or for precise manual adjustments.

Pro tip: If composition accuracy and framing flexibility matter, the GH2 has an edge here. The WS80 sacrifices this for compact ruggedness.

Sensor Technology and Image Quality

Under the hood, the image sensor determines your photo's detail, depth, dynamic range, and performance in varied lighting.

The GH2's Four Thirds sensor is significantly larger than the WS80’s 1/2.3" CCD. This size advantage translates into superior image quality: better light gathering, improved dynamic range, and cleaner noise performance at higher ISOs.

Our lab tests confirm the GH2 handles low light scenes remarkably well relative to cameras of its vintage, with ISO 3200 usable and ISO 12800 reserved for emergencies. It also produces richer colors and deeper tonality because of its more advanced Bayer-based CMOS sensor and wider dynamic range (~11.3 EV per DxOMark).

The WS80’s small sensor limits its image quality potential, especially in dim conditions. It tends to exhibit more noise at ISO speeds above 400 and delivers less vibrant colors and contrast. The lack of raw image support constrains post-processing flexibility.

This difference makes the GH2 a better professional or enthusiast option if you demand ultimate image fidelity and control.

Autofocus Systems: Speed, Accuracy, and Tracking

Accurate autofocus (AF) systems influence how effortlessly you can capture sharp images across subjects and conditions.

The GH2 shines with a sophisticated contrast-detection AF system featuring 23 points and face detection. Its continuous AF and tracking functions enable it to follow moving subjects more reliably - valuable in sports, wildlife, or general photography.

Pentax’s WS80 AF is basic, with only 9 points and no tracking or face detection. AF is limited to single-shot focus, making it suitable mainly for stationary subjects. In low light, autofocus can become slow or hunt noticeably.

For fast-paced photography such as wildlife, sports, or events where subjects move unpredictably, the GH2’s AF system delivers better performance and flexibility.
