Panasonic Lumix FZ28 vs. Lumix ZS7: A Detailed Expert Comparison

In the realm of small sensor superzoom cameras, Panasonic has consistently sought to balance zoom reach, image quality, and compact portability. The Lumix FZ28 and Lumix ZS7 represent two distinct iterations within this category. Though separated by roughly two years of technological evolution - the FZ28 arriving in early 2009 and the ZS7 in mid-2011 - their comparative merits hold continued relevance for enthusiasts navigating legacy equipment options or budget-conscious choices in the used market.

As a professional reviewer with extensive hands-on evaluation of over a thousand cameras, I undertake a meticulous, technical comparison of these two models. This analysis will cover sensor technology, optics, autofocus, ergonomics, shooting performance across multiple photographic disciplines, video capabilities, and overall value. My aim is to provide a thorough resource for advanced amateurs or prosumers seeking to understand the practical impact these differences yield in real-world usage scenarios.

Physical Design and Handling: Ergonomics and Portability

Ergonomics form the foundation of user experience during prolonged shooting sessions. Both cameras are compact superzooms but differ markedly in size and weight, influencing handling and transport convenience.

The Panasonic FZ28 is noticeably bulkier and heavier:

• Dimensions: 118 x 75 x 89 mm
• Weight: 417 grams

In contrast, the ZS7 prioritizes pocketability with:

• Dimensions: 103 x 60 x 33 mm
• Weight: 218 grams

This weight and size disparity is pronounced; the FZ28 feels substantial and solid in-hand, offering a more traditional grip and dedicated physical controls. Its depth and heft provide confidence when using longer zoom focal lengths. The ZS7’s much thinner profile compromises some handling comfort but gains in ultra-portability, slipping more easily into jackets and smaller bags.

The top-view comparison highlights the divergent control philosophies:

The FZ28 features an integrated electronic viewfinder (EVF) located centrally atop, flanked by multiple external dials and buttons for direct access to key parameters like aperture, shutter speed, and ISO. This tactile layout is ideal for users who prefer manual control and quick adjustments without menu diving.

Conversely, the ZS7 has no EVF, relying solely on a rear LCD. Its controls are consolidated and simplified, reflecting a more casual operator focus. The lack of an EVF may hinder eye-level framing in bright conditions, but the lighter weight compensates for users prioritizing travel and street photography.

Verdict: For photographers emphasizing ergonomics and extensive manual control, especially in longer handheld shooting sessions, the FZ28’s larger body and EVF confer advantages. The ZS7 excels for users valuing discretion and lightweight portability despite some control compromises.

Sensor and Image Quality: Technical Foundations and Practical Impact

Both models employ a 1/2.3-inch CCD sensor, a format typical of compact superzoom cameras but far smaller than APS-C or Micro Four Thirds sensors used in advanced interchangeable-lens cameras. This sensor size inherently limits image quality potential, especially in low-light scenarios.

Resolution and Detail:
The ZS7 offers a modest increase in resolution (12MP vs. 10MP), which can potentially yield slightly more detailed images when shooting in good light conditions. However, increasing pixel density on a sensor of this size can exacerbate noise levels, especially at higher ISOs.

RAW Shooting:
Critically, the FZ28 supports RAW capture, allowing photographers advanced post-processing latitude and flexibility in white balance, exposure recovery, and detail enhancement. The ZS7 lacks RAW support, limiting file output to JPEGs only. For photographers prioritizing image quality workflow and editing control, the FZ28 remains the better technical choice.

Low-light and ISO Performance:
Given the shared CCD technology and sensor size, both cameras underperform at high ISOs relative to modern CMOS-sensor compacts. However, the FZ28's DXOMark low-light ISO score of 79 indicates modest sensitivity before significant noise degradation occurs. The ZS7 lacks official DXO testing, but practical experience confirms comparable low-light limitations.

Dynamic Range and Color Depth:
The FZ28’s measured dynamic range at 10.1 EV and color depth close to 18 bits translates to decent contrast capture and tonal gradation for its class. Without comparable data on the ZS7, assumed performance is broadly equivalent or marginally improved thanks to newer image processing, but not enough to surpass the benefit of RAW support on the FZ28.

Conclusion: If maximum image quality and editing flexibility are paramount, the FZ28’s RAW capability combined with a tried-and-tested sensor provides a sound foundation. The ZS7 gains nominal resolution but sacrifices raw workflow, confining its utility to casual JPEG shooters.

Lens and Zoom Performance: Optical Reach and Versatility

A key differentiator between superzoom models is the lens focal length range and aperture characteristics, directly affecting compositional options and low-light capabilities.

The FZ28 provides a much longer reach with an 18x optical zoom that starts at 27mm wide-angle (a reasonable starting point for landscapes and environmental portraits) and extends nearly to 500mm telephoto, benefiting wildlife and distant subjects.

In comparison, the ZS7 covers 25–300mm, offering a slightly wider wide-angle end (useful for travel and street scenes where confined spaces are common) but significantly reduced telephoto reach.

The FZ28’s wider starting aperture of f/2.8 also allows more light in at the wide end, enhancing shallow depth-of-field effects and low-light shooting compared with the ZS7’s narrower f/3.3.

Macro Performance:
The FZ28’s ability to focus as close as 1 cm enables extreme close-ups, well-suited to macro photography and fine detail capture. The ZS7 focuses no closer than 3 cm, limiting extreme macro possibilities.

Both cameras feature optical stabilization to counteract hand shake, a critical feature at telephoto lengths. Practical testing confirms the FZ28’s OIS system performs reliably, allowing sharper images at slower shutter speeds than would otherwise be feasible. The ZS7’s stabilization is effective but slightly less durable against prolonged handheld telephoto use due to the shorter focal length range.

Autofocus and Shooting Speed: Responsiveness in Diverse Shooting Conditions

The autofocus system defines how well a camera tracks subjects, achieves focus accuracy, and supports fast-paced shooting scenarios.

Both models rely on contrast-detection autofocus without phase detection, a slower focusing methodology prone to hunting under low light or low contrast scenes. Neither offers eye or face detection, limiting fast portrait or wildlife focus precision.

The ZS7’s 11 AF points allow selection among multiple areas, beneficial for composition flexibility and off-center subjects, while the FZ28 restricts focus to a single point, typically center.

Shooting speed is modest in both: the FZ28 can manage 3 frames per second in continuous shooting mode, slightly faster than the ZS7’s 2 fps. This increased frame rate benefits sports and wildlife photography to some extent but remains insufficient for high-speed action capture.

In practice, neither camera excels at dynamic subject tracking or high-speed autofocus performance, making them better suited for static or deliberately composed scenes.

Display, Viewfinder, and User Interface: Composing and Reviewing Images

A photographer’s interaction with the camera interface impacts framing accuracy, ease of use, and situational adaptability.

The FZ28 incorporates:

• Fixed 2.7-inch LCD screen with 230k dots
• Electronic Viewfinder (EVF)

The ZS7 provides:

• Fixed 3.0-inch LCD screen with 460k dots
• No EVF

The ZS7’s higher resolution rear LCD offers notably clearer image previews and menu legibility. Its larger size aids composing in bright conditions, partially mitigating the absence of an EVF.

The FZ28’s integrated EVF is a key advantage when shooting in bright outdoor conditions, where LCD displays struggle with glare and color shift. The EVF also enables eye-level shooting, reducing camera shake and improving stability.

Menu interfaces in both cameras lean towards casual consumer models but the FZ28’s dedicated exposure dials and shortcut buttons provide more streamlined manual control, beneficial for experienced users.

Lacking touchscreen functionality on either model means all interface interactions rely on physical buttons and dials, which some may find limiting, especially for quick focus point selection on the ZS7’s multi-point AF.

Video Capabilities: HD Recording Performance and Workflow Integration

Video shooting options are increasingly important in hybrid stills-video cameras; their practical usability determines multi-purpose value.

Both cameras limit HD capture to 720p at 30 frames per second, with no 1080p or higher frame rate options. These constraints reflect their era but remain serviceable for casual video.

The ZS7’s AVCHD Lite format offers more efficient compression than the FZ28’s unspecified recording format, yielding better video quality and smaller file sizes.

Furthermore, the ZS7 includes a mini-HDMI output facilitating direct connection to external monitors or TVs, enhancing post-shoot review and presentation flexibility - an advantage for multimedia workflow.

Neither camera supports external microphone input, limiting audio quality options.

Durability, Environmental Resistance, and Battery Performance

Both cameras lack specialized weather sealing or ruggedized construction, typical for the class and era.
