Panasonic FZ100 vs LX5: A Comprehensive Comparison for Enthusiasts and Pros

In the landscape of digital photography circa the early 2010s, Panasonic carved two distinct paths with the Lumix FZ100 and Lumix LX5. Both cameras appeal to enthusiasts seeking compact yet versatile tools, yet they approach imaging from fundamentally different angles. The FZ100 is a robust superzoom bridge camera with an impressively broad focal range, while the LX5 is a compact, fast-lensed point-and-shoot aimed at those craving portability and quality in a small form factor.

Having spent many hours testing both models extensively - running them through real-world scenarios, lab measurements, and cross-discipline shooting - I want to lay out an authoritative comparison that covers every essential aspect. From sensor technology and autofocus performance to ergonomics and value, this is a head-to-head you can trust to guide your next purchase.

First Impressions: Size, Handling, and Design

At a glance, the Panasonic FZ100 and LX5 couldn’t be more different in handling and design philosophy. The FZ100 has an SLR-like bridge camera body that commands presence on the desk. It feels substantial and deliberate in the hand, offering good grip security for long telephoto shooting. In contrast, the LX5 is a compact that slips into a jacket pocket - ideal for discreet street shooting or travel.

The FZ100’s heft, measuring 124x82x92 mm and weighing 540 grams, supports a robust set of controls and a nicer heft that many photographers appreciate - especially when using longer zooms. The LX5, at just 110x65x43 mm and 271 grams, champions convenience and travel-friendly portability, but this reduced size means more reliance on menus and fewer dedicated physical controls.

Moving on to the control layout, the FZ100 sports a thoughtfully arranged top deck with intuitive dials and buttons placed within easy reach, enhancing one-handed operation during dynamic shooting. The LX5's compact form constrains button real estate but keeps the layout generally user-friendly for a camera of its size.

Both cameras employ the Venus Engine FHD processor, promising speedy image rendering and responsiveness in their respective classes - more on how that translates into experience soon.

Sensor Specifications and Image Quality Nuances

Diving deeper, sensor technology shapes every photo’s quality. The Panasonic FZ100 features a 1/2.3-inch CMOS sensor with 14 megapixels, a fairly standard "small sensor" for superzoom models. Meanwhile, the Panasonic LX5 ups sensor size and quality, sporting a 1/1.63-inch CCD sensor with 10 megapixels.

This difference in sensor size is crucial. Larger sensors tend to provide better image quality - especially in low light and dynamic range - thanks to bigger photosites and improved light-gathering capability. The LX5’s sensor offers a significantly larger surface area (about 62% more), which directly impacts noise performance and tonal gradations.

What surprised me during testing is how the LX5’s CCD sensor yields richer color depth - DxOMark ratings confirm a 19.6-bit color depth against the FZ100's untested but historically lower small sensor performance. The LX5’s dynamic range is also better at 10.8 EVs, compared to what we’d expect from a typical 1/2.3-inch CMOS sensor. Low-light ISO performance lags behind modern sensors but holds up well considering the era.

The FZ100, though newer in design, is limited by the smaller sensor. It achieves 14MP resolution but pushes the boundaries at higher ISOs above 800, with visibly more noise creeping in. That said, the larger pixel count on a smaller sensor can yield sharper images under controlled lighting.

So, in a portrait or landscape shoot where image quality matters, the LX5’s larger sensor and CCD technology offer a tangible advantage - especially if you’re shooting in JPEG or working with RAW workflows at moderate ISOs.

LCD and Viewfinder Insights: Interface and Usability

Camera interface usability cannot be overstated when evaluating user experience. Both cameras feature a rear 3-inch screen at 460k-dot resolution, but their articulation capabilities diverge notably. The FZ100 sports a fully articulated display - hugely valuable for low or high-angle shooting positions and for self-portrait use.

The LX5's fixed screen is perfectly sharp but limits flexibility. Moreover, while the FZ100 features a built-in electronic viewfinder (EVF), the LX5 does not have a native EVF but offered an optional accessory viewfinder. The FZ100’s EVF lacks resolution specs but provides standard coverage, aiding composition in bright light when LCDs can be washed out.

In practical field usage, the articulating screen plus integrated EVF makes the FZ100 a better fit for photographers who value compositional freedom and more robust visual feedback. The LX5, while limiting in this area, compensates with faster start-up times and a smaller footprint - ideal if your shoot favors speed and stealth over compositional gymnastics.

Autofocus Performance and Speed Dynamics

Autofocus (AF) is often the deciding factor between cameras when shooting fast-moving subjects or capturing fleeting moments. The Panasonic FZ100 implements a contrast-detection AF system with face detection and continuous AF tracking. Although it lacks phase detection, the FZ100 manages to deliver surprisingly peppy autofocus speeds for its class, especially in continuous AF mode where it can track subjects adequately.

Contrast this with the LX5, whose contrast-detection AF offers 23 focus points but no continuous or tracking AF modes. The LX5 relies on single AF mode, making it less suitable for fast action photography.

While testing wildlife and sports sequences, the FZ100’s ability to sustain 11 frames per second shooting (burst rate) also means it can capture more decisive moments, whereas the LX5 tops out at a modest 3 fps.

These differences suggest the FZ100 is better suited for photography genres demanding speed and subject tracking - wildlife, sports, and street shooting where subjects move unpredictably.

Lens Architecture: Zoom Reach vs. Aperture Speed

The defining strength of the FZ100 is undeniably its 24x superzoom lens equivalent to 25–600mm with a maximum aperture spanning f/2.8–5.2. This reach makes the FZ100 a versatile powerhouse for telephoto-heavy shooting - think wildlife, distant landscapes, and sports events. Not to mention, the built-in optical image stabilization helps to mitigate shake at long focal lengths.

On the other hand, the LX5 features a 3.8x zoom lens equivalent to 24–90mm with a faster max aperture range of f/2.0–3.3. This lens favors low-light shooting and shallow depth of field, lending the LX5 strength in portraits, street, and macro photography. The wider aperture also facilitates smoother bokeh and subject separation.

Neither camera has interchangeable lenses, so you’re tied to their fixed optics, but each lens is optimized for different shooting philosophies - the FZ100 is a telephoto workhorse, the LX5 a fast-lensed compact.
