In this comprehensive comparison, I’ll walk you through how these differences translate to real-world performance, helping you decide which camera deserves your investment.

How These Cameras Stack Up Out of the Box

Before we get into nuanced performance, it’s key to understand their physical and technical foundations.

Size, Weight, and Ergonomics

The Lumix FX75 is a notably compact and lightweight camera, weighing just 165g and measuring 103x55x23 mm. Its slim profile makes it a natural choice for discretion and travel convenience. By contrast, the LX5 is heavier and bulkier at 271g and 110x65x43 mm, reflecting its more advanced features and larger sensor.

In hands-on use, the FX75’s ultra-compact size makes it pocket-friendly but somewhat limited in grip comfort during extended shooting. The LX5’s robust body, although less portable, provides a better grip and physical control layout for more deliberate photography sessions.

Control Layout and Usability

The LX5 offers more dedicated dials and buttons, including manual focus and exposure controls, aperture and shutter priority modes, and an external flash hot shoe - a boon for serious users. The FX75, designed for straightforward point-and-shoot operation, lacks manual exposure options and external flash compatibility, limiting its flexibility.

From my experience, the LX5's well-thought-out physical interface allows quick adjustments while shooting, improving responsiveness. The FX75’s more simplified controls suit casual shooters but may frustrate enthusiasts wanting creative control.

Sensor Technology and Image Quality: The Heart of the Matter

No matter the external specs, image quality is king. Let’s break down how sensor differences shape photographic output.

Sensor Size and Resolution

The LX5 sports a 1/1.63-inch CCD sensor with a surface area of approximately 44.87 mm² and a resolution of 10 megapixels. By contrast, the FX75 uses a smaller 1/2.3-inch CCD sensor measuring just 27.72 mm² but boasts a higher 14-megapixel count.

At first glance, more megapixels might seem better with the FX75. However, the LX5’s larger sensor provides bigger photodiodes, enhancing light-gathering capability, dynamic range, and noise performance - areas where the FX75 is comparatively limited.

In extensive side-by-side testing, the LX5 delivers cleaner images, especially in low-light and high-contrast scenarios, with richer color depth (measured DXO color depth of 19.6 bits, unmatched by the FX75).

Raw Support and Image Processing

The LX5 supports RAW capture, enabling flexible post-processing and superior image control for professionals and advanced enthusiasts. The FX75 does not offer RAW support, restricting users to JPEGs and limiting image editing latitude.

Both cameras deploy a Panasonic Venus Engine image processor (FX75 has the HD II version, LX5 features the newer FHD variant), which efficiently handles noise reduction and image sharpening. However, the LX5's newer processor contributes to slightly better high ISO images and finer detail retention.

Focus Systems and Shooting Responsiveness

Fast and accurate autofocus (AF) is a vital practical factor impacting usability, especially for action or candid photography.

Autofocus Features and Performance

• FX75 uses a basic contrast-detection AF system with touch AF capability but no face or eye detection.
• LX5 employs a more advanced 23-point contrast AF system, delivering more precise focus including center-weighted AF options but also lacks face detection.

In my field tests, the LX5’s AF provides quicker acquisition and better lock-on performance for static subjects. The FX75’s AF often hunts in lower light or complex scenes, resulting in missed shots during dynamic shooting.

Neither camera offers continuous AF tracking ideal for fast-moving subjects, so wildlife or sports photographers may find both cameras limiting compared to modern phase-detection systems.

Burst Shooting and Shutter Speeds

The LX5 supports 3 frames per second (fps) continuous shooting up to a few frames, while the FX75 manages 2 fps - adequate for casual sequences but insufficient for serious action photography.

Maximum shutter speed stands at 1/4000s for LX5, allowing better handling of bright light and motion freeze; FX75 caps at 1/2000s.

Screen, Viewfinder, and User Interface

User interface nuances impact framing and reviewing images - critical for accurate composition in all lighting conditions.

• LX5 features a larger 3.0-inch fixed LCD with 460k-dot resolution, enabling clearer image preview and menu navigation.
• The FX75's 2.7-inch screen with only 230k-dot resolution displays images less crisply and is harder to judge fine image details on-site.

Neither camera has a built-in viewfinder, but the LX5 offers an optional electronic viewfinder accessory, a rarity and advantage for bright outdoor shooting.

Touchscreen capabilities are present on the FX75, helping with quick focus point selection but somewhat underwhelming given the limited AF system. The LX5 lacks touchscreen but compensates with traditional physical control reliability.

Real-World Performance Across Photography Genres

Understanding how these cameras perform across disciplines sheds light on their practical usability.

Portrait Photography

• LX5 handles skin tones with warmer, more natural rendering thanks to its superior color depth and larger sensor. The wider max aperture (f/2.0 at wide end) facilitates attractive background blur for subject isolation.
• FX75's smaller sensor and variable max aperture (f/2.2-5.9) restrict its bokeh capability; portraits can appear flat or less nuanced, especially in indoor light.

Both lack advanced eye-detection AF, so close attention to focus placement is needed.

Landscape Photography

• The LX5’s larger sensor and higher dynamic range (10.8 EV) capture richer details in highlights and shadows, critical for landscapes with varied lighting.
• The FX75 delivers acceptable results in bright daylight but suffers with limited shadow detail and noise in shadows.

Neither camera is weather-sealed, limiting rugged outdoor use; however, portability makes the FX75 travel-friendly.
