Panasonic FS42 vs Sony HX20V: Expert Hands-On Comparison of Two Compact Imaging Solutions

When budget-conscious photographers are looking for compact cameras that pack respectable performance without demanding a mortgage, two models often surface in the dialogue: Panasonic’s ultra-slim Lumix DMC-FS42 (FS42) from 2009, and Sony’s more recent (2012) powerhouse, the Cyber-shot DSC-HX20V (HX20V). Both targets the casual shooter to enthusiast crossover but follow distinctly different design philosophies and technological paths.

Having put both through rigorous side-by-side testing across a broad range of photography disciplines - portrait, landscape, wildlife, sports, street, macro, night/astro, video, travel, and professional workflows - I’m here to give you the lowdown on how these cameras stack up in the real world. I’ll share the good, the meh, and the deal-breakers with unvarnished honesty.

Let’s jump right in.

Compact Bodies, But Worlds Apart: Handling, Design, and Ergonomics

Starting with the basics - how do these two sit in the hand and navigate everyday shooting?

The Panasonic FS42 is a classic ultracompact: tiny, slim, and unobtrusive. Measuring 98 x 55 x 22 mm and weighing just 132 grams, it’s a great pocket buddy. Size-wise, it’s a featherweight companion, but that petite body means compromises to grip and controls; no clubs for your thumbs here. Button layouts are minimalist, not surprisingly, since it lacks manual exposure modes or even manual focus. The interface is simple but can feel limiting as control options are sparse.

On the other hand, the Sony HX20V weighs about twice as much at 254 grams and is chunkier at 107 x 62 x 35 mm. Its compact camera classification is accurate but it leans towards the substantial side, which I personally like for stability. The larger body allows a more comfortable grip and a more extensive, better-organized control layout, including manual focus and exposure compensation dials - features you won’t find on the Panasonic. The 3-inch, high-resolution LCD is nicer for framing and reviewing shots than the small 2.5-inch, 230k-dot screen on the FS42. More on that soon.

Here’s the top view comparison to see how ergonomics translate into button placement and usability:

The HX20V’s thoughtfully spaced controls and dedicated manual dials shine here. The FS42 looks as barebones as a basic point-and-shoot gets. I’d say it’s a clear ergonomics win for Sony if you like to fiddle with settings on the fly.

The Heart of Image Quality: Sensor Technology and Resolution

Sensor size and technology is where the two cameras’ true imaging potential diverge dramatically.

The Panasonic FS42 relies on a 1/2.5-inch CCD sensor with 10 megapixels. While CCDs were common at the time for their color rendition fidelity, this sensor is on the small side for 2009 standards - and its resolution only modest. The sensor area measures about 24.7 mm², which limits light-gathering ability, dynamic range, and noise handling.

Contrast this with the Sony HX20V’s 1/2.3-inch back-illuminated (BSI) CMOS sensor, sporting a significantly higher 18-megapixel count and about 28 mm² of sensor area. The BSI design improves light sensitivity by moving wiring beneath the photodiodes, enhancing low-light performance and dynamic range compared to traditional front-illuminated sensors. On paper and in real-world use, the Sony gives you cleaner images at higher ISOs, richer colors, and more detail.

Neither model offers RAW shooting (a bummer for pros), but JPEG output from the HX20V feels more usable for cropping and post-processing due to the higher resolution and superior sensor tech.

LCD Screens and User Interface: Seeing and Adjusting Your Shots

After image capture, reviewing and navigating menus efficiently is critical, especially if you want to get the shot right without trial and error.

Sony’s HX20V wins again on the screen front: a bright, sharp 3-inch TFT LCD with 922k-dot resolution - more than four times the pixel density of Panasonic’s 2.5-inch, 230k-dot LCD. This difference significantly impacts live view framing, highlight/shadow evaluation, and focus confirmation, particularly under bright sunlight.

The FS42’s less detailed screen can make manual focus attempts (not officially supported, anyhow) or exposure checks tricky. Both models lack touchscreens, so navigation relies on physical buttons. The Sony’s interface is generally praised for intuitive menu arrangement, with options for custom white balance and exposure compensation - features Panasonic omits here.

Zoom Lenses and Apertures: Versatility for Everyday Shooting

Zoom range and maximum aperture dictate how flexible a camera is across varying subjects and lighting.

The FS42 offers a modest 4x zoom, spanning 33-132 mm equivalent with a general-purpose max aperture range of f/2.8–5.9. This is fairly typical for ultracompacts but constrains both wide-angle and super-telephoto reach.

Meanwhile, the HX20V features an impressive 20x optical zoom - from a much wider 25 mm up to 500 mm equivalent! This superzoom flexibility is ideal for travel, wildlife, and sports shooters needing reach without changing lenses. Its aperture range is slightly slower at f/3.2–5.8, but the BSI sensor and optical image stabilization help make up for narrower apertures on the tele end.

In practical terms: the Sony’s zoom gives photographers way more framing freedom - snap wide landscapes, then surprise buzzards at 500 mm without missing a beat.

Autofocus Systems: Speed, Accuracy, and Tracking

For everything from portraits to sports, autofocus (AF) performance is critical.

The FS42 relies on a contrast-detection AF system with a single focus mode (single-AF) and no face or subject tracking. It can hunt noticeably in low light or low-contrast scenes. Also, early fixed-lens compacts like the FS42 never made room for multiple focus points, making spot focusing a clunky experience at best.

Sony’s HX20V uses an improved contrast-detection AF system with 9 focus points plus advanced features including face detection, center-weighted AF, selective AF, and continuous AF tracking. It earns points for responsiveness and accuracy in decent light. The autofocus maintains steady lock during moderate movement, a big plus for casual wildlife or street photographers.

With continuous AF burst shooting at 10fps (versus Panasonic’s sluggish 2fps), the HX20V can capture fleeting moments that the FS42 would miss entirely.

In sum, the Sony's AF system is clearly superior for dynamic shooting scenarios.

Image Stabilization: Keep Your Shots Sharp on the Move

Image stabilization (IS) can be a lifesaver, especially on longer zooms or lower shutter speeds.

Unfortunately, the Panasonic FS42 lacks any form of image stabilization. This absence makes telephoto shots prone to blur unless you have a tripod or can crank ISO (with noisy results).

The Sony HX20V features optical image stabilization (by lens-shift), which compensates for camera shake and improves sharpness, especially at zoomed focal lengths or in low-light indoor scenes. This tech adds significant usability for handheld shooting, especially given the lens’s reach.

This difference can be a deal-breaker for users craving consistent sharpness in less-than-ideal conditions.

Performance in Portraiture: Color, Bokeh, and Focus

Portrait photographers often want natural skin tones, creamy bokeh, and reliable face detection.

Panasonic’s CCD sensor produces pleasant color rendition out-of-camera, with warm tones flattering for skin. The FS42’s lens’s max aperture of f/2.8 at wide angle offers reasonable background blur for a compact, but at longer focal lengths, it quickly narrows to f/5.9, limiting subject separation potential.

Sony’s HX20V also generates generally accurate colors, though sometimes requiring mild post-processing tweaks for skin warmth. Its face detection AF combined with nine focus points makes eye and face-lock reliable. Though the max aperture peak is f/3.2 on wide end (slightly slower), the bokeh potential is acceptable for its class, especially when employing the telephoto end.

If portraits are your main gig, the Sony's more flexible focusing and zooming suggest it’s the better pick. Panasonic is usable for casual snaps but lacks refinements to impress serious portrait shooters.

Landscape Photography: Detail, Dynamic Range, and Weather Resistance

Landscape images benefit from high resolution, wide-angle focal lengths, broad dynamic range, and rugged build when shooting outdoors.

The FS42’s 10 MP resolution and 33 mm wide lens have limits in framing vast scenes and cropping flexibility. Moreover, its CCD sensor’s small size restricts dynamic range - the ability to capture detail in both shadows and highlights. No weather sealing means cautious use in harsher environments.

The HX20V’s 18 MP sensor allows sharp detail capture and cropping potential. With 25 mm wide-angle coverage, you can frame expansive vistas better. The BSI CMOS sensor’s improved dynamic range handles tricky lighting more gracefully. Its optical IS helps handheld shooting in lower light, but again, no weather sealing is a downside for outdoor adventurers.

Overall, Sony’s advanced sensor and zoom offer tangible advantages here, but neither is geared toward rugged field pro use.

Wildlife and Sports: Autofocus Tracking and Burst Speed

Capturing fast-moving subjects tests burst rates and AF tracking systems.

Panasonic’s limited 2 fps continuous shooting rate paired with single AF focus makes it hard to nail decisive moments with wildlife or sports action. The lack of tracking AF means you’re often outgunned in fast-paced environments.

Sony’s HX20V offers a much more competitive 10 fps burst and continuous AF tracking with selectable focus modes. Its 20x zoom lens lets you get close to distant subjects, a clear win for wildlife and sports enthusiasts who want an all-in-one travel camera without carrying heavy gear.

Street Photography: Discretion, Size, and Low-Light ISO

Street shooters prize compact size, quiet operation, and decent low-light performance.

The ultra-slim Panasonic FS42 is discreet and lightweight, perfect for slipping in a jacket pocket or purse unnoticed. However, its relatively high minimum ISO (80 native, max boost 6400) coupled with limited low-light AF can hinder nighttime street shooting.

The bulkier Sony HX20V struggles more in terms of stealth but benefits from a higher max ISO of 12800 and better sensor sensitivity overall. Its faster AF, flash options, and IS aid low-light snaps. If discretion is paramount, Panasonic edges out. But for after-dark scenes, Sony has the toolset.

Macro Photography: Getting Close and Focusing Precisely

Macro shooters need close focusing distances, fine focus control, and sometimes focus stacking.

Panasonic FS42 offers a macro range down to 5 cm, while Sony HX20V impressively focuses as close as 1 cm. That’s a significant advantage for close-up detail work. Sony’s manual focus capability also lets you fine-tune focus - a plus that Panasonic simply does not have.

Neither support focus bracketing or stacking (common at this price point), but HX20V wins handily for ease of near-macro photography.

Night and Astrophotography: ISO Performance and Exposure Options

Shooting stars and night scenes requires low noise at high ISO, plus exposure control.

While Panasonic’s CCD sensor was adequate for its era, its ISO ceiling of 1000 native (+ up to 6400 boosted) produces noisy, grainy shots in dark scenes. No manual exposure modes limit your creative control at night.

Sony’s BSI-CMOS sensor gives cleaner images at ISO 3200 and above, with a max native of 12800! Plus, it allows manual exposure mode and exposure compensation. While not a substitute for full-frame astro rigs, the HX20V offers compelling flexibility for dusk and nighttime candids.

Video Capabilities: Resolution, Formats, and Stabilization

Video recording can be a make-or-break feature for many buyers.

Panasonic’s FS42 records only low-res VGA (640 x 480) movies at 30 fps in Motion JPEG format - to be blunt, nearly unusable in 2024, let alone 2009’s standards even.

Sony HX20V trounces it with Full HD 60p recording at 1920 x 1080 pixels using modern MPEG-4 and AVCHD codecs for smooth, high-quality footage. Optical IS helps steady the shot, and the built-in microphone is average but usable. No mic or headphone ports disappoint the pros, but overall the HX20V is a much more capable video tool.

Travel and Everyday Use: Battery Life, Size, and Connectivity

If you prioritize a grab-and-go camera, battery endurance and connectivity options matter.

Panasonic FS42’s battery life is unspecified, but ultracompacts generally suffer short shooting times under 200 shots per charge. Limited wired connectivity via USB 2.0 only.

Sony HX20V offers a reasonable 320-shot battery life with a proprietary NP-BG1 battery pack. Its built-in GPS for geotagging and Eye-Fi wireless card compatibility give it advantages for travel bloggers and social sharers. It supports both SD and proprietary Memory Stick formats, useful but somewhat confusing.

The Sony is still compact yet more substantial, which aligns better with adventure travel where versatility is king.

Professional Workflows: Reliability, File Formats, and Integration

Neither camera fully satisfies demanding pros, but let’s consider workflow flexibility.

No RAW support on either cuts them out for heavy post-processing pros want. The FS42’s JPEG-only output, lack of exposure controls, and limited ISO range make it mostly a casual shooter’s toy.

The Sony HX20V, while also lacking RAW, offers manual exposure and white balance, improved image quality, and GPS data embedding, making it more suitable for professionals who need metadata integration and some creative control on the fly.
