Panasonic Lumix FS42 vs Sony Cyber-shot TX9: A Deep Dive into Two Ultracompacts from the Late 2000s

Selecting a compact camera that marries portability and decent image quality remains a nuanced task - especially when balancing legacy models like the Panasonic Lumix FS42 (2009) against the Sony Cyber-shot TX9 (2010). Both cameras occupy the ultracompact niche, targeting casual shooters and travelers who prioritize ease of use and convenience over interchangeable lenses.

Having personally tested thousands of cameras over the past 15+ years, I embarked on a detailed comparison of these two models to see how they perform across photography genres, usability, and technical artistry. In this article, we’ll dissect what each camera brings to the table, analyze their strengths and shortcomings, and offer guidance on which suits your photographic ambitions.

Size, Weight & Handling: Designed for Portability with Distinct Ergonomic Philosophies

First impressions matter. Handling a camera can make or break the shooting experience, especially for a pocketable ultracompact.

Physically, both cameras are petite, but the FS42 (98x55x22mm at 132g) cubes up more squarely, while the TX9 (98x60x18mm, 149g) has a sleeker, thinner profile. Panasonic’s FS42 feels slightly chunkier, with a higher center of gravity, which can be both a blessing and a curse. It offers a more substantial grip surface for those with larger hands, reducing accidental slips. Conversely, the TX9’s slimmer body emphasizes discreetness - ideal for urban street shootouts or travel scenarios where minimalism is key.

The TX9 includes a 3.5-inch touchscreen LCD, noticeably larger and more refined than the FS42’s 2.5-inch fixed, low-resolution display. This impacts comfort and ease of framing - more on the screens shortly.

My experience with ultracompacts tells me that while smaller size is coveted, it should never compromise secure handling. Panasonic’s design leans toward pragmatic ergonomics, while Sony bets on streamlined aesthetics and touchscreen convenience.

The Layout Story: Controls, Interface & Usability

Neither camera targets advanced manual shooters, but their control designs reflect differing UI philosophies.

The FS42 sticks to a straightforward, button-centric design - with physical zoom toggles and a mode dial that’s simple but limited (no manual exposure modes). The buttons are a bit cramped but tactile enough under finger. There’s no touchscreen, so navigation relies on these traditional controls.

Sony’s TX9 side-steps this with a capacitive touchscreen, integrating a simpler button layout alongside touch-based menu access. The tactile buttons are fewer but well spaced, and the touchscreen allows intuitive focus point selection and menu browsing - a welcome boost in user experience for casual shooters. The FS42’s lack of touchscreen can feel archaic today, but even in 2009, it was lagging behind.

For quick composition adjustments and playback, the TX9 is clearly ahead. Additionally, Sony’s inclusion of slow sync flash and spot metering offers more shooting flexibility, even if exposure controls remain fully automatic.

Sensor & Image Quality: The Heart of the Matter

Understanding sensor tech and image results is critical for any camera - small sensors in ultracompatcs often struggle with noise, dynamic range, and resolution limitations.

Panasonic FS42 uses a 1/2.5" CCD sensor at 10 megapixels, with sensor dimensions of approximately 5.7x4.3mm and a sensor area of 24.74mm². At its time, CCDs were standard, favoring color depth but commonly suffering from higher noise and slower readout compared to CMOS sensors.

Sony TX9 steps up with a 1/2.3" BSI-CMOS sensor of 12 megapixels (6.17x4.55mm, 28.07mm²), moderately larger and with backside illumination technology that generally improves low light sensitivity and noise characteristics.

Looking at max native ISO, FS42 peaks at 1000 ISO, with boosted modes going as high as 6400 but at great noise cost. TX9 boosts up to 3200 ISO natively, courtesy of its BSI-CMOS sensor, and manages cleaner images in dim conditions.

Image wise, the FS42 produces solid daylight shots with decent color fidelity but limited dynamic range. Highlights tend to clip quickly, and shadows get murky under challenging light. The TX9 benefits from better sensor sensitivity and processing via the Bionz engine, delivering cleaner mid-ISO shots and improved handle on detail retention across shadows.

We tested sample photos in a controlled laboratory scene with smooth gradients and sharp focus. Panasonic’s output exhibits the softer edges typical of CCD sensors, while Sony’s images show crisper detail and finer noise texture. This translates to better landscape and street photo quality on the TX9.

Screens & Live View Experience: Making Framing a Breeze

The Panasonic FS42’s 2.5-inch screen with 230k-dot resolution is barely usable by today’s standards, showing limited contrast and small size that hampers accurate composition - especially for fine details in landscape or macro work.

Sony’s TX9 vastly improves with a 3.5-inch 922k-dot touchscreen. It’s bright, responsive, and supports intuitive tap-to-focus functionality, making it an excellent live view experience for quick point-and-shoot use, framing in street or travel scenarios, and even for macro focus confirmation at close distances.

The touch display also offers accelerated menu navigation and playback review, which is often overlooked but vital for photographers moving quickly through shoots.

Lens & Zoom: Coverage and Optics in Everyday Photography

Both cameras feature fixed zoom lenses with 4x optical zoom but differ in focal length ranges and maximum apertures:

• Panasonic FS42: 33–132 mm (35mm equivalent), f/2.8–5.9
• Sony TX9: 25–100 mm (35mm equivalent), f/3.5–4.6

In essence, the FS42 offers a longer telephoto reach but with a slower aperture at the zoom end. The TX9’s lens starts wider at 25mm (great for landscapes and group shots) but doesn’t reach as far telephoto.

For portrait photographers, a wider max aperture is key to controlling depth of field and obtaining creamy bokeh. Neither lens is truly “fast,” but the FS42’s f/2.8 wide end is somewhat advantageous for shallow depth of field effects and better low-light capabilities. TX9’s lens, while not as bright, benefits from optical image stabilization to help compensate for shutter shake in dimmer conditions, where FS42 lacks any stabilization.

Close focusing is another strength area - TX9 can focus as close as 1cm, a boon for macro work, compared to the FS42’s 5cm minimum focus distance. This makes Sony a superior choice for enthusiasts who like to explore textures and fine details up close.

Autofocus and Shooting Speed: Keeping Up with the Moment

A camera’s autofocus (AF) system and burst shooting performance are essential to capturing fleeting subjects, whether wildlife or sports.

The FS42 uses a simple contrast-detection AF with a single AF point and no continuous or tracking focus mode. It is adequate for stationary subjects in good light but noticeably sluggish in low light or on moving targets.

Sony’s TX9 improves upon this with 9 focus points, center-weighted metering, and basic tracking AF capabilities. Although it does not have phase-detection AF (not common in compacts of that era), its AF responsiveness is superior to Panasonic’s, especially in well-lit environments.

Burst shooting is an area where the TX9 markedly outpaces the FS42. Panasonic maxes out at a slow 2fps continuous rate with limited buffer depth, whereas Sony supports 10fps burst shooting at a slightly reduced resolution. This makes the TX9 far more apt for sports or action bursts.

Flash & Low Light Performance

Built-in flash capabilities differ substantially:

• FS42: less powerful with a 6.3m range, multiple modes including red-eye reduction and slow sync.
• TX9: 3.8m range, with Auto, On, Off, and Slow Sync but no explicit red-eye reduction.

In practical shooting, the FS42’s flash throws more light to subjects in darker rooms or dim environments. However, its lack of stabilization means shutter speeds can become limiting.

The TX9, while offering less flash distance, supports optical image stabilization, which - combined with a better sensor - produces cleaner handheld low-light shots without flash. The flicker of a weaker flash is often outweighed by more usable available light exposure when you have stabilization.

Video Recording: Not Just Still Photography Anymore

While neither camera will replace a dedicated video camera, video shooting remains a valuable secondary function.

Panasonic FS42 offers low-resolution video: max 848x480 at 30fps in Motion JPEG. It is stilted and niche at best - suitable only for casual, low-res clips.

Sony TX9 steps up to full HD (1920x1080) at 50fps in AVCHD format - a notable leap in quality and frame rate for smooth, sharp video. This is quite impressive for an ultracompact from 2010, supporting better video capture for travel diaries or quick social media clips.

Neither camera supports microphone input or advanced audio controls, but TX9's HDMI output offers more flexibility for external displays or recording.

Battery Life & Memory: Practical Shooting Considerations

Unfortunately, Panasonic does not publish detailed battery life stats for the FS42; based on usage and battery type, expect modest shooting duration - typical of ultracompacts from the period.

Sony TX9's NP-BN1 battery offers approximately 220 shots per charge (CIPA standard), which is adequate for casual day trips but would require carrying a spare for extended sessions.

Storage wise, both accept SD/SDHC cards, but TX9 also accepts Memory Stick Duo formats, offering versatility depending on existing memory card libraries.

Connectivity Is Modest but Different

Neither camera offers wireless connectivity beyond TX9’s Eye-Fi card compatibility for wireless image transfers - a rare feature then, easing photo sharing via Wi-Fi-enabled SD cards.

Only TX9 includes an HDMI output port as well, enhancing its connectability to HD displays, which the FS42 lacks.

Durability & Environmental Resistance

Neither camera has significant weather sealing or rugged body construction. They are intended for casual everyday use, not for harsh outdoor environments or professional fieldwork under adverse conditions.

Real-World Photography Tests: Across Genres

To understand how these cameras perform across popular photography types, I tested both on curated shoots and everyday scenarios.

• Portraits: The FS42’s slightly faster wide aperture helps in softly separating subjects from backgrounds, though neither camera produces dramatic bokeh. Sony’s sharper images and better color rendition lend portraits a crisper look, but skin tone rendering is fairly neutral on both.

• Landscape: TX9’s wider lens and higher resolution sensor result in more detailed, vibrant landscape photos with better shadow recovery. FS42 scenes tend to lose detail in darker foliage.

• Wildlife: Neither camera is ideal. FS42’s lagging AF and slow burst make it frustrating to capture animals in motion; TX9's 10fps burst and improved AF make it the better, though still limited, candidate.

• Sports: Again, FS42’s 2fps continuous shooting is insufficient for capturing dynamic athletic moments. TX9’s faster burst helps but is constrained by buffer and autofocus speed.

• Street Photography: TX9's slim body, silent-ish operation, and touchscreen facilitate discreet street candid shots much better than FS42’s boxier form and slower interface.

• Macro: The TX9 wins here handily, focusing down to 1cm with stabilized optics, delivering richly detailed macro shots that FS42 cannot approach.

• Night/Astro: FS42 maxes at ISO 1000 but produces soft, noisy low light images. TX9’s BSI sensor with IS yields cleaner night shots, though long exposures are limited.

• Video: TX9’s 1080p at 50fps is practical for handheld travel video; FS42 video capabilities are basic and poorly suited beyond documenting family moments.

• Travel: Both portable, but TX9 delivers better all-around image quality, video, and usability, justifying its slightly higher bulk and cost.

• Professional Work: Neither camera suits pro workflows due to no RAW, limited controls, and modest sensors.

Verdict in Scores and Value

Considering technical specs, handling, and output, the Sony TX9 clearly outperforms the Panasonic FS42 across most axes. The improvements in sensor tech, autofocus, burst shooting, touchscreen usability, and video capture place it in a higher tier among ultracompacts of its time.

However, this comes at a premium - the TX9 was priced around $799 at release versus FS42’s $579. For budget buyers seeking a straightforward compact with basic functions, FS42 can still deliver passable snapshots, especially in good light and at moderate zooms.

Final Thoughts: Lessons from Decade-Old Ultracompacts

While technology has marched on since these cameras hit the market, examining them side-by-side offers useful perspectives on incremental innovation in sensor design, AF systems, and user interfaces.

The Panasonic FS42 embodies a simpler era relying on CCD sensors and button-driven control. The Sony TX9 pushes into the early era of CMOS BSI chips and touchscreen convenience - adding modern usability to legacy compact sensibilities.

Both cameras fulfill specific niches but serve as reminders that ultracompacts are always a compromise. If you’re aiming for serious artistic control or professional-grade files, a mirrorless or DSLR is non-negotiable. But for snapshots and everyday carry with decent image quality and video - especially given the 2010-era Tech improvements - the Sony TX9 remains the more forward-looking choice.
