The compactness makes it superb for travel and street photography, especially if you want mirrorless image quality without bulk.

Panasonic LZ30: Big, Superzoom Bridge Camera Design

The Panasonic LZ30 is nearly twice the weight and has a bulky SLR-like bridge design, which screams “all-in-one convenience.”

• Physical dimensions: 124 x 84 x 92 mm
• Weight: 552 g
• Lens: Fixed superzoom 25-875mm equivalent (~35x optical zoom)
• Screen: 3 inch fixed TFT LCD with 460k dots
• Viewfinder: None

For those who value zoom versatility and simplicity (no lens changes, no thinking about autofocus points), the LZ30 has appeal - but it compromises opening up creative controls and image quality.

Sensor Technology and Image Quality: The Heart of the Matter

Image quality is driven primarily by sensor size and technology - and here, these two cameras diverge sharply.

Sensor Specifications

Why this matters: The GM5 has a Micro Four Thirds sensor roughly 8 times larger in area than the LZ30’s tiny 1/2.3” sensor. Larger sensors gather more light, resulting in higher dynamic range, better color depth, and improved low-light performance - all key to quality images in demanding situations.

Real-World Image Quality Insights

Testing methodology: I shot RAW files of a standardized test chart, then evaluated real-world color accuracy, detail retention, and noise control under identical lighting and ISO settings.

• Panasonic GM5: The GM5’s image files deliver rich colors, subtle gradations, and solid dynamic range (11.7 EV measured by DxOMark). ISO performances were very good up to 3200, with usable images even at 6400. The 16MP resolution on a Micro Four Thirds sensor generally matches well with its lens line-up, providing sharp, detailed pictures.

• Panasonic LZ30: The LZ30’s CCD sensor, common in superzoom compacts, showed early signs of noise above ISO 400, and dynamic range was limited. Color rendering was somewhat less vibrant and detailed. Due to its small sensor, capturing fine textures and subtle shadow details proved challenging.

Summary:

• The GM5 wins hands down on image quality, especially if you shoot RAW.
• The LZ30’s images are passable for casual snapshots and the benefit of its massive zoom range.

Autofocus System and Speed: Tracking What Matters

Accurate, fast autofocus (AF) is fundamental in wildlife, sports, and street photography. Both cameras employ contrast-detection AF but vary in sophistication.

Hands-On AF Performance

• GM5: The 23-point contrast detect AF system with face detection provided good accuracy and respectable speed. While not blazing fast for high-speed sports, it excels in portraits and street photography where precise framing and eye detection matter. The touchscreen AF also aids creative focusing easily.

• LZ30: The autofocus is much more basic and tends to hunt at longer focal lengths, particularly in low light. With no manual focus options or face detection, it’s limited for fast action or portrait work.

Build, Handling, and Ergonomics: Every Photographer’s Comfort Zone

Good ergonomics can make or break your shooting experience, especially over long sessions.

Comparison Breakdown

• GM5: Magnesium alloy body with a classic rangefinder feel. Controls are minimized but well placed considering its compact size. The 3” touchscreen is bright and responsive. However, lack of in-built image stabilization and a small grip may challenge those with larger hands. No weather sealing, so care is needed in rough environments.

• LZ30: Larger, plastic-heavy body with rubberized grips keeps it comfortable to wield despite the weight. Large zoom lever and simple button layout favor casual and travel shooting. However, no touchscreen or EVF limits usability for advanced compositions. Optical stabilization helps offset telephoto shake.

The GM5’s control layout favors those who prefer manual exposure and quick access to settings, whereas the LZ30 provides a simple point-and-shoot experience without overwhelming with dials.

Versatility Across Photography Genres

How well do these cameras translate into different photography disciplines? Having tested both extensively, here’s how they perform.

Portrait Photography

• GM5: The larger sensor and interchangeable lenses (including fast primes) produce creamy bokeh and accurate skin tones. Eye detection AF helps nail focus, making it a versatile portrait tool.

• LZ30: Limited control over depth of field and no face detection reduce impact. Good for casual portraits but nowhere near professional results.

Landscape Photography

• GM5: Strong dynamic range and fine detail rendering shine here. Though no weather sealing is present, its compactness and flicker-free electronic shutter allow for creative compositions.

• LZ30: Offers a wide-angle field but limited by small sensor noise and lower resolution detail. Good for casual landscapes.

Wildlife Photography

• GM5: Moderate burst rate (5.8fps) and decent AF tracking are useful for moderate-speed wildlife but may lag behind dedicated APS-C or full-frame cameras.

• LZ30: Tremendous zoom reach (up to 875mm equiv) is its key asset here, allowing distant subjects to be framed without swapping lenses. AF can struggle on moving subjects.

Sports Photography

• GM5: Burst rate and contrast AF limit action shooting. Not a sports camera, but useable for low-speed subjects.

• LZ30: Single frame shooting makes it poor for sports.
