First Impressions: Size, Handling, and Build Quality

Both Panasonic cameras offer distinct physical designs tailored to different needs.

Panasonic FZ40 - Classic Bridge-Style Superzoom

The FZ40 features a bulky, SLR-style bridge body aimed at providing a DSLR-like feel with a massive zoom lens built in. Its weight and substantial grip help stability during long telephoto shots, but the overall heft can challenge portability, especially for travel or street shooting.

Panasonic LX100 - Compact Yet Robust

The LX100 shrinks down to a compact form-factor with a sleek, understated design. It’s crafted for photographers who prize pocketability without sacrificing high image quality from a large sensor.

By comparing physical dimensions and weight side-by-side, you see a telling difference:

• FZ40: 120 x 80 x 92 mm at 494 g
• LX100: 115 x 66 x 55 mm at 393 g

Although both cameras offer good durability, neither sports weather sealing or ruggedization features, so cautious handling in adverse conditions is advised.

Ergonomics and grip: The FZ40’s larger grip suits prolonged shooting sessions, particularly in wildlife or sports. The LX100’s smaller, more simplified controls favor mobility enthusiasts and street photographers who prefer less weight on their body.

Sensor Technology and Image Quality: Mega Zoom vs. Large Sensor Compact

The heart of any camera’s image quality lies in its sensor technology and size.

Panasonic FZ40: Small 1/2.3" CCD Sensor

The FZ40 packs a 14MP CCD sensor measuring just 6.08 x 4.56 mm - the standard size for many superzoom bridge cameras. CCD sensors were more common a decade ago due to color fidelity but are outpaced today in noise handling compared to CMOS.

Low-light performance and dynamic range are modest at best, with limited ISO sensitivity topping out at 6400 (though noise becomes unmanageable past 800). The optical low-pass filter (anti-aliasing) slightly softens fine detail but reduces moiré.

Panasonic LX100: Large Four Thirds CMOS Sensor

The LX100’s sensor is a much larger Micro Four Thirds chip (17.3 x 13 mm), offering a 13MP resolution - the slightly lower pixel count helps each pixel gather more light, improving dynamic range and noise management. This sensor is combined with CMOS technology, enabling faster readouts, live view autofocus, and superior video capabilities.

This size difference is visually noticeable:

• FZ40 Sensor area: 27.72 mm²
• LX100 Sensor area: 224.90 mm² (8x larger surface area)

In practical terms, this translates to much better image quality from the LX100 - crisper details, improved color depth, and more usable high ISO settings, making it a better tool for demanding applications like portraits and night/astro photography.

Lens and Zoom Range: Versatility or Image Quality Priority?

Here, the cameras’ core philosophies really diverge.

FZ40: Massive 25-600mm Equivalent Zoom (24x)

This camera is for those who crave reach. The 25-600mm lens covers everything from wide-angle landscapes to distant wildlife and sports shots. However, the variable aperture (F2.8-5.2) starts fast but narrows significantly by telephoto, affecting performance in low light at long zooms.

The lens delivers decent sharpness in the center but softness increases noticeably at full zoom and wider apertures.

LX100: Fast 24-75mm Equivalent Lens (3.1x)

The LX100 offers a luminous, much faster zoom lens with a maximum aperture ranging F1.7 at wide to F2.8 at telephoto. This makes a dramatic difference in low-light scenarios, providing smoother bokeh and shallower depth of field ideal for portraits and street photography.

The shorter zoom range does limit reach but boosts image quality and creative control. Sharpness across the frame is excellent, aided by the high-quality glass and larger sensor.

Autofocus, Shooting Speed, and Burst Performance

Speed and accuracy in autofocus and continuous shooting determine suitability across genres like wildlife, sports, and street.

FZ40 Autofocus: Basic Contrast-Detection

With only single-point AF and contrast-based focusing, the FZ40 feels sluggish in action scenarios. Autofocus hunting in low light or tracking moving subjects is a common frustration. Continuous AF and face or eye detection are absent, limiting practical use for dynamic photography.

Burst shooting maxes out at 2 fps, suitable only for snapshots rather than sports or wildlife sequences.

LX100 Autofocus: Advanced 49-Point Contrast Detection with Face Tracking

Despite lacking phase detection, the LX100’s autofocus benefits from 49 points and intelligent face detection and tracking. It’s snappier and more accurate in varied lighting, locking onto subjects reliably.

Burst shooting up to 11 fps with AF lock is impressive for a compact, allowing for capturing critical moments in sports or fast-paced street scenes.

User Interface and Control Layout: Intuitive or Basic?

How a camera feels in your hands influences creativity and efficiency. Panasonic offers different interaction models here.

FZ40 Interface: Classic Dial and Button Setup

While the FZ40 offers dedicated exposure modes and a limited set of buttons, its small 230k pixel LCD restricts preview clarity. No touchscreen means that all adjustments require physical buttons which may be less intuitive to those used to modern interfaces.

Menus are straightforward but dated.

LX100 Interface: Higher-Resolution Displays with Touch AF

LX100 shines with a 3" 921k resolution rear screen providing detailed image review. It has no touchscreen, but touchscreen AF is supported for focusing. The electronic viewfinder is far superior, boasting 2.76M dots and 100% coverage for precise framing.

Ergonomic controls mimic a traditional rangefinder-style camera, with dedicated aperture ring and exposure dials, giving professionals tactile satisfaction.

Image Stabilization and Video Capabilities

Stabilization and video outperform for handheld shooting and multimedia versatility.

FZ40: Optical Image Stabilization Only

This bridge camera’s optical stabilization helps minimize blur on long zooms but isn’t image-stabilized sensor-based. Video is limited to 720p HD and standard frame rates, constraining creative video work. No external microphone inputs means limited sound quality.

LX100: Optical Image Stabilization with 4K Video

The LX100 records 4K UHD video at 30fps, a significant advantage for hybrid shooters prioritizing both stills and video. It supports efficient compression formats (AVCHD and MPEG-4) and boasts 4K photo mode (shooting 8MP stills extracted from 4K footage).
