FujiFilm S4000 vs Panasonic Lumix DMC-ZS40: An In-Depth Comparison of Two Small-Sensor Superzooms

In the ever-evolving realm of superzoom cameras, balancing versatility, image quality, and portability is a challenging feat. Today, I want to dive into a detailed comparison of two compact giants from the small-sensor superzoom category: the FujiFilm FinePix S4000, launched in early 2011, and the Panasonic Lumix DMC-ZS40 (also known as TZ60), which arrived in 2014.

Both promise a massive 30x optical zoom covering a focal range of 24-720mm (in 35mm-equivalent terms) but bear significant technological and ergonomic differences born of three years' development and differing design philosophies. Drawing from hands-on testing and technical analysis over several years, we'll dissect their performance through multiple photographic disciplines - portrait, landscape, wildlife, macro, and more - and conclude with clear recommendations tailored to diverse photographic needs.

Let's start by sizing them up, literally.

Assessing Size and Ergonomics: Handling Matters as Much as Optics

The FujiFilm S4000 sports a “bridge camera” SLR-like body typical of the early 2010s, while the Panasonic ZS40 leans toward a more compact, travel-friendly form factor. Ergonomics drastically affect how we engage with a camera during extended shoots.

FujiFilm S4000 – Solid Grip, But Heftier

Measuring roughly 118 × 81 × 100 mm and weighing 540 grams with four AA batteries, the S4000 has a noticeably larger and chunkier footprint. Its “SLR-like” grip and control layout afford a steadier hold for longer sessions or telephoto shots, which is crucial when extending to that max 720mm focal length. The AA battery system adds bulk but offers the convenience of easy replacement anywhere, which can be a boon during remote fieldwork.

Panasonic ZS40 – Compact and Lightweight

By contrast, the Panasonic ZS40 sits at 111 × 64 × 34 mm and weighs just 240 grams with its proprietary battery. This makes it a relatively pocketable zoom compact - more of a grab-and-go travel companion. The slim profile enhances portability but sacrifices some grip solidity, particularly noticeable at full zoom when handshakes amplify.

These form-factor choices align clearly with different user priorities: the FujiFilm pitches a more sturdily built tool, and Panasonic targets travelers requiring compactness and weight savings.

Top Control and Design: Intuitive vs. Minimalist

How a camera feels in the hands during operation is paramount to a photographer's workflow and enjoyment. Let’s look at how these two pack their functions on their bodies.

The FujiFilm S4000 follows a traditional approach with tactile dials and buttons for aperture priority, manual exposure, exposure compensation, and custom white balance. This kind of hands-on control layout is familiar and efficient for users accustomed to DSLR-style workflows. However, some buttons feel a touch cramped, reflecting its older design.

The Panasonic ZS40 uses a more streamlined design, with fewer dedicated buttons and a smaller mode dial. Its control scheme trades instant access for compactness. The top LCD screen is absent on both, but the Panasonic’s interface is more menu-driven. For users who prefer quick adjustments without diving into extensive menus, the FujiFilm’s controls may feel more fluent.

Sensor and Image Quality: The Heart of the Matter

Superzoom cameras often face scrutiny for smaller sensors with inherent noise and dynamic range limitations. Both models here use modest 1/2.3” sensors, but key distinctions lie in sensor type, resolution, and processing.

FujiFilm FinePix S4000 - 14MP CCD Sensor

The S4000 uses a 14MP CCD sensor, a technology once renowned for color rendition and clean mid-ISO images but generally slower in readout speeds. Its max native ISO caps at 1600, with boosted ISO up to 6400, though noise rises considerably past ISO 800 in practice. The CCD sensor, coupled with analogue signal processing inherent to FujiFilm's older pipeline, provides pleasant color tones but comparatively limited dynamic range. Notably, it lacks RAW file support, which restricts post-processing latitude.

Panasonic Lumix ZS40 - 18MP CMOS Sensor with Venus Engine

The ZS40 features a higher-resolution 18MP CMOS sensor combined with Panasonic’s Venus Engine processor. While the sensor size matches Fuji’s at approximately 28 mm², the switch to CMOS brings faster readouts, superior high ISO handling, and native support for RAW files - hugely valuable for demanding shooters.

The max native ISO extends to 3200, with boosted to 6400. Thanks to advanced noise reduction routines and a more agile processor, real-world shooting at ISO 1600 and beyond is cleaner and more usable than the FujiFilm.

Across landscape and low-light genres, the Panasonic’s wider ISO range and RAW flexibility enable better detail retention and creative freedom.

Display and Viewfinder: Composing Your Shot

Composing in bright environments or at awkward angles is where screen quality and viewfinder experience come into play.

The FujiFilm S4000 sports a fixed 3-inch LCD with a modest 460k-dot resolution, which looks noticeably grainy and dull under bright sunlight. Conversely, the Panasonic ZS40 doubles down on resolution with a 920k-dot TFT LCD featuring anti-reflective coating, offering a significantly sharper, more contrast-rich display that enhances framing and focus checking.

Both incorporate electronic viewfinders (EVFs), but the FujiFilm’s has unspecified resolution and lower coverage (approx. 97%), whereas the Panasonic’s EVF boasts 200k-dot, 100% coverage. Although neither EVF matches enthusiast-grade models, the Panasonic’s viewfinder is more pleasing and helpful for critical composition in bright outdoors.

Autofocus and Shooting Performance: Tracking Fast-Moving Subjects

For wildlife and sports photographers, autofocus (AF) speed, accuracy, and burst rates are critical criteria to evaluate.

The FujiFilm S4000 provides contrast-detection AF with face detection and basic tracking capabilities but lacks phase detection nor sophisticated AI-supported AF. Its continuous shooting clocks at a sluggish 1 fps, making it unsuitable for fast-action capture.

The Panasonic ZS40 offers contrast-detection AF with 23 selectable focus points, more refined tracking algorithms, and face detection. Critically, it supports a much faster continuous shooting rate of 10 fps, which can be invaluable for capturing fleeting moments or wildlife behavior.

In field trials, I noted Panasonic’s AF system acquires focus quicker and tracks moving subjects more reliably, especially under decent lighting. The FujiFilm occasionally hunt for focus, particularly at full zoom or low contrast scenes - testament to its older AF technology.

The Versatility of the Lens: Same Reach, Different Personality

Both cameras share a superzoom 24-720mm (35mm equivalent) lens with 30x optical zoom, but aperture ranges and macro performance differ.

The FujiFilm has a maximum aperture of f/3.1 at wide end, closing to f/5.9 at telephoto. Macro focusing distance is a remarkable 2 cm, letting you approach subjects quite closely for intimate close-ups.

The Panasonic is slightly slower, with f/3.3–6.4 maximum aperture but a still respectable macro focus at 3 cm. On the stabilisation front, the FujiFilm employs sensor-shift image stabilization, physically moving the sensor to compensate. Panasonic uses optical image stabilization built into the lens element system.

In everyday use, I found Panasonic’s optical IS more effective and less prone to hunting, resulting in sharper hand-held shots at slower shutter speeds.

Handling a Variety of Photography Disciplines

Let’s inspect how these cameras hold up across common photographic situations, weighing their strongest and weakest suits.

Portrait Photography

Portrait work demands nuanced skin tone rendition, smooth bokeh, and dependable eye detection AF.

Fuji’s CCD sensor renders pleasing colors with a slightly warm cast flattering for skin tones, but depth of field control is limited - -at f/5.9 telephoto, background blur is minimal, and bokeh character is average. Face detection AF works, but eye detection is missing.

Panasonic benefits from higher resolution and RAW capability for more dynamic editing of skin textures and tones. Its 23-point AF aids more precise focus on faces, though eye AF is also missing. Bokeh remains shallow but similar in quality.

Overall, Panasonic offers better post-processing versatility; Fuji delivers pleasing straight-out-of-camera colors.

Landscape Photography

Landscape imagery relies heavily on resolution, dynamic range, and weather sealing.

Neither camera offers environmental sealing, a notable drawback in inclement conditions.

Panasonic edges ahead on resolution (18MP vs 14MP) providing extra detail capture. The CMOS sensor’s better high dynamic range preserves shadow and highlight detail more effectively, a boon over Fuji’s more limited DR CCD.

Both cameras offer multiple aspect ratios, but Panasonic’s extra capture modes and full RAW output grant it a superior workflow in capturing and refining landscapes.

Wildlife Photography

This genre demands fast AF, telephoto reach, and burst shooting.

Both cameras’ 720mm reach provides adequate telephoto reach but optical quality tends to soften near zoom limit.

Panasonic’s 10 fps burst combined with reliable AF makes it far more capable in tracking dynamic wildlife moments versus Fuji’s sluggish single shot per second cadence and less refined AF.

Sports Photography

In general, neither camera is optimized for professional sports work due to small sensor and limited fast autofocus, but Panasonic’s burst rate and tracking work make it the choice between these two for casual sports shooting.

Street Photography

Street photography favors discretion, low-light capability, and portability.

Panasonic’s compact and lightweight body clearly wins here; the FujiFilm is larger and potentially more obtrusive.

Lower light ISO performance also favors Panasonic.

The FujiFilm’s closer macro focusing distance (2 cm vs 3 cm) provides slightly more flexibility in capturing small details.

However, Panasonic’s superior AF precision and stabilization mitigate this advantage somewhat.

Night and Astrophotography

Small sensors strain in astrophotography. But Panasonic’s higher native ISO and RAW support allow more aggressive noise reduction and detail recovery than Fuji’s limited ISO and JPEG-only output.

Neither model is ideal for advanced astro, but Panasonic introduces more usable options.

Video Capabilities

FujiFilm records 720p video at 30fps using Motion JPEG codec, an older format resulting in larger file sizes and less efficient compression.

Panasonic steps up with Full HD 1080p recording up to 60fps using MPEG-4 or AVCHD formats, a significant upgrade for video enthusiasts.

Neither offers external microphone inputs or 4K capabilities, but Panasonic’s better stabilization aids smooth footage.

Travel Photography

Size, weight, battery, versatility, and convenience converge here.

Panasonic’s compact size, built-in GPS, wireless connectivity, and efficient battery pack make it the natural choice for travelers.

Fuji’s AA battery system offers field-replaceable power - a perk if you’re in locations without recharging options.
