Panasonic GH2 vs Panasonic LZ30

Panasonic Lumix GH2 vs Panasonic Lumix LZ30: An Expert Comparative Analysis for Photography Enthusiasts

In the realm of digital imaging, selecting the optimal camera hinges on a precise evaluation of technical specifications, real-world usability, and intended photographic applications. This comprehensive review rigorously compares two Panasonic models: the advanced mirrorless Lumix GH2 and the bridge-style superzoom Lumix LZ30. Both cameras occupy distinct niches and exhibit markedly different design philosophies, sensor architectures, and ergonomic paradigms. Leveraging over 15 years of hands-on camera testing, we dissect their attributes across key photography disciplines, focusing on performance metrics that materially affect image quality, operational efficiency, and creative potential.

Physical Design and Handling: Ergonomics Rooted in Purpose

A camera’s physical ergonomics profoundly influence control fluidity and shooting comfort - critical factors for enthusiasts and professionals who demand reliability during extended shoots. The GH2 inherits its SLR-style mirrorless form factor typical of Panasonic’s Micro Four Thirds lineup, whereas the LZ30 aligns with the bridge camera archetype, featuring a fixed superzoom lens and simplified controls.

Dimensions and Weight

• GH2: 124 x 90 x 76 mm; 442 grams
• LZ30: 124 x 84 x 92 mm; 552 grams

Despite a similar footprint, the LZ30 is noticeably bulkier and heavier by over 100 grams, largely due to its integrated zoom lens and AA battery power system - which, while convenient for replacements, contributes to increased weight.

Control Layout

The GH2 offers a more sophisticated control framework with dedicated dials, buttons, and an electronic viewfinder. The LZ30 adopts simplified controls conducive to casual shooting but limits direct manual adjustments.

Photographers requiring granular exposure management and tactile feedback will favor the GH2’s layout, which better supports rapid changes and customization. The LZ30’s setup is less conducive to dynamic shooting parameters but benefits users prioritizing ease of use.

Sensor Technology and Image Quality Potential: The Core Imaging Engine

Sensor size and technology remain definitive factors in image quality, dynamic range, noise performance, and depth of field control.

Sensor Size and Type

• GH2: 17.3 x 13 mm Four Thirds CMOS (approximately 225 mm² sensor area)
• LZ30: 6.17 x 4.55 mm 1/2.3-inch CCD (approximately 28 mm² sensor area)

The GH2 employs a significantly larger Four Thirds-sized sensor, approximately 8x the area of the LZ30’s sensor, which translates to distinctly superior light-gathering capability, reduced noise, and finer tonal gradations. This differential is amplified by the CMOS architecture in the GH2 offering enhanced sensitivity and speed over the CCD sensor in the LZ30.

Resolution and Pixels

Both cameras feature 16-megapixel resolution; however, the GH2 leverages its larger sensor to provide a more refined pixel pitch, yielding better image clarity, less diffraction, and superior performance at higher ISOs.

Image Processing

The GH2 incorporates Panasonic’s Venus Engine FHD processor, facilitating advanced noise reduction, color rendering, and video encoding. The LZ30 lacks an equivalent dedicated processor, reflected in its more modest video capabilities and slower continuous shooting.

In practice, the GH2 produces images with richer color depth (DxO Color Depth: 21.2 bits) and expanded dynamic range (11.3 EV), compared to the LZ30 which lacks official DxO metrics but is expected to fall significantly behind given its sensor constraints.

Display and Viewfinding: Real-Time Composition and Feedback

Effective framing and reviewing demand high-resolution displays and reliable viewfinders.

• GH2: 3-inch fully articulating touchscreen, 460k dots, TFT LCD with wide viewing angles; electronic viewfinder (EVF) with 100% coverage and 0.71x magnification.
• LZ30: 3-inch fixed TFT LCD, 460k dots; lacks any form of electronic or optical viewfinder.

The GH2’s articulated screen and EVF allow for flexible shooting angles and precise framing in bright conditions, accommodating diverse shooting scenarios including macro, low angle, and video. The absence of a viewfinder on the LZ30 significantly impairs compositional stability in bright daylight or action shooting environments, relegating users to the LCD.

Autofocus, Focusing Flexibility, and Performance in Dynamic Scenarios

Autofocus (AF) speed, tracking, and accuracy become paramount for sports, wildlife, and fast-moving subjects.

• GH2: Contrast-detection AF with 23 selectable points, face detection, continuous AF tracking, and selective AF modes.
• LZ30: Contrast-detection AF with unknown focus point count, center-weighted AF, continuous and single AF modes, no face or eye detection.

The GH2’s multi-point AF and tracking capabilities are more sophisticated, enabling enhanced subject acquisition and retention in complex scenes. The LZ30’s AF system is workable for general photography but struggles with rapid movements, hampering usability for wildlife or sports photography.

Burst Performance and Shutter Range: Capturing the Decisive Moment

Burst Shooting

• GH2: 3 fps continuous shooting
• LZ30: 1 fps continuous shooting

Although modest by modern standards, the GH2’s faster burst rate supports moderate action sequences; the LZ30’s much slower rate can miss critical frames in rapidly changing scenes.

Shutter Speed Range

• GH2: 1/60 to 1/4000 second
• LZ30: 1/15 to 1/2000 second

The GH2 affords greater flexibility for freezing motion with faster shutter speeds and managing exposure in bright conditions.

Lens Ecosystem and Optical Versatility

One of the fundamental divergences lies in lens interchangeability.

• GH2: Micro Four Thirds mount with compatibility to 107 lenses (including primes, zooms, and specialty optics).
• LZ30: Fixed 25-875 mm equivalent (35mm format) zoom lens, F3.0-5.9 aperture range.

The GH2’s interchangeable lens system offers unparalleled creative latitude, from ultra-wide to telephoto, and state-of-the-art optics with wide apertures conducive to shallow depth of field, low light, and specialized disciplines such as macro or portraiture. The LZ30’s lens is impressive in reach but compromises on maximum aperture, which restricts low-light capacity and depth of field control.

Image Stabilization and Low-Light Capacity

• GH2: No in-body image stabilization; depends on optically stabilized lenses.
• LZ30: Optical image stabilization implemented in lens.

While the LZ30 offers built-in lens stabilization - which is beneficial for handheld telephoto shots - the GH2's options expand considerably with the availability of numerous OIS lenses in the Micro Four Thirds ecosystem. Its larger sensor enhances high ISO usability dramatically, accommodating low-light scenarios better despite its lack of sensor-shift stabilization.

Video Recording Potential: Meeting Hybrid Content Demands

For combined photographic and videographic use:

• GH2: Full HD 1920x1080 at 24, 30, 60 fps; AVCHD and Motion JPEG formats; external microphone input.
• LZ30: HD 1280x720 at 30 fps; Motion JPEG; no microphone port.

The GH2 clearly targets hybrid shooters, delivering advanced video recording options, higher frame rates at full HD resolution, and professional-grade audio connectivity. Conversely, the LZ30’s basic HD video and lack of audio input render it suboptimal for serious videography.

Battery Life and Power Management

• GH2: Proprietary rechargeable battery pack, approximately 330 shots per charge.
• LZ30: Uses 4x AA batteries, approximately 380 shots per set.

The LZ30’s use of readily available AA batteries is advantageous in settings without access to recharging facilities. The GH2’s higher power consumption is balanced by battery pack efficiency and accessory options, yet may require carrying spares for extended use.

Connectivity and Storage Options

• Both cameras offer single SD/SDHC/SDXC card slots.
• Neither incorporates wireless connectivity (no Wi-Fi, Bluetooth, NFC).
• GH2 offers HDMI output; LZ30 does not.

The lack of wireless features is a point of note for modern workflows; however, the GH2’s HDMI facilitates direct monitoring and external recording, an asset for video professionals.

Build Quality and Environmental Robustness

Neither camera is weather-sealed or shockproof. For outdoor photographers operating under adverse conditions, the GH2’s more rugged SLR-style construction affords marginally better durability, though neither is recommended for harsh environments without external protection.

Practical Application Across Photography Genres
