Panasonic Lumix FX700 vs Pentax Optio VS20: A Hands-On Compact Camera Comparison for Every Photographer

With countless compact cameras on the market, picking one that aligns well with your photography style - be it casual snapshots, travel, or occasional telephoto needs - can be a challenge. Today, I’m diving deep into a side-by-side comparison of two notable compact point-and-shoot cameras: the Panasonic Lumix DMC-FX700 (announced in mid-2010) and the Pentax Optio VS20 (early 2012). While they share the compact form factor and fixed lenses, their designs, features, and capabilities differ in quite insightful ways.

Based on my extensive experience testing over a thousand cameras for practical performance and real-world usability, I will break down how these two compacts stack up across multiple genres, sensor tech, ergonomics, and value. Whether you're a casual snapshooter, a travel photographer, or a compact camera collector – read on to discover which model could be the better fit for you.

Getting Hands-On: Form Factor and Ergonomics First

Before considering specs and features, handling a camera reveals much about usability in everyday conditions. Both the FX700 and VS20 belong to the "compact camera" category but have slightly different physical philosophies.

The Panasonic FX700 is noticeably sleeker and more pocket-friendly. Its dimensions measure approximately 104 x 56 x 25 mm with a lightweight 176 g body, crafting a low-profile design that fits comfortably in one hand or jacket pocket. This slimness enhances portability, a key for street photographers and travelers valuing discretion.

On the other hand, the Pentax VS20 is chunkier - around 111 x 61 x 38 mm, weighing 235 g. While still compact compared to DSLRs or mirrorless cameras, it’s less svelte. The extra girth, however, affords a more substantial grip, which may benefit those who prefer a firmer hold or plan to zoom extensively.

Looking at the control layouts, the FX700 features straightforward button topography with a generally less cluttered interface, incorporating essential dials and buttons accessible via thumb and forefinger without strain. The touchscreen addition on the FX700 facilitates quicker menu navigation and focusing taps - a nice touch given its 2010 vintage.

The VS20, meanwhile, opts for traditional button-only controls with no touchscreen. This might appeal to photographers who prioritize tactile feedback over screen interaction or prefer physical buttons in bright conditions.

Overall, if you're after the smallest, most portable body suited for quick grabs and casual outings, the FX700 pulls ahead. If you prefer a more grounded grip with extensive telephoto reach (more on that lens soon), then don’t discount the VS20’s heftier form.

Sensors and Image Quality: CMOS vs CCD and Resolution Talk

The cornerstone of any camera's image quality lies in its sensor. Both these compacts boast the same sensor size, the common 1/2.3-inch format measuring 6.08 x 4.56 mm with a sensor area of about 27.72 mm², but Panasonic and Pentax have chosen different sensor technologies and pixel counts.

• The PanasonicFX700 sports a 14-megapixel CMOS sensor paired with the Venus Engine FHD processor. CMOS sensors often excel in speed and better noise handling in low light, thanks largely to their on-chip architecture. The FX700’s sensor native sensitivity ranges from ISO 80 to 6400 - quite generous for a compact of its era.

• The Pentax VS20 equips a 16-megapixel CCD sensor. While CCDs traditionally deliver excellent color fidelity and smoother tonal gradations, they tend to lag in high-ISO performance and power efficiency relative to CMOS designs. Its ISO range starts at 100, also maxing out at 6400.

So what does this mean for image quality?

The CMOS sensor in the FX700 generally provides cleaner images at moderate to high ISOs thanks to more modern noise suppression algorithms baked into the Venus engine. Here, you’ll find slightly better noise control in indoor and evening shots, critical if you shoot handheld in low light.

Conversely, the VS20’s CCD sensors tend to excel in lower ISO settings due to their color depth and dynamic range characteristics, albeit at the cost of noise creeping in more aggressively as sensitivity climbs.

Neither camera supports RAW image files, an understandable limitation in their compact class, but restricts post-processing flexibility, especially for advanced enthusiasts.

Maximum image resolutions favor the Pentax VS20 at 4608 x 3456 pixels versus Panasonic’s 4320 x 3240 pixels. This edge could appeal to those who plan for large prints or cropping, although the real-world detail differences are subtle and influenced heavily by lens sharpness and processing.

In sum, if low light and ISO versatility is a priority, lean towards the FX700’s CMOS sensor and processor combo. For daylight shooting where color rendition at base ISO matters most, the VS20’s sensor holds its own.

Lenses and Zoom Power: Daylight Walkabout or Superzoom Adventures?

The fixed lens choice defines each camera's creative applications. With the FX700, Panasonic offers a 24-120 mm equivalent focal length, marking a 5x zoom with a bright F2.2 aperture wide open on the shortest end, dimming to F5.9 at full zoom. This means you get reasonably wide angles suitable for landscapes, portraits, and street scenes, with a decent zoom reach for moderate telephoto shots.

The Pentax VS20 features a whopping 28-560 mm equivalent zoom - a compelling 20x zoom range at apertures from F3.1 to F4.8. That’s serious telephoto reach in compact form, ideal for wildlife, sports from a distance, or avoiding crowd hassles.

While the FX700’s lens provides more light-gathering ability at the wide end, which translates to better low-light performance and shallower depth of field (hello, creamy bokeh in portraits), it doesn’t come close to the VS20’s reach.

One caveat: extreme superzooms on small sensors, like the VS20, often exhibit compromised sharpness and contrast at long focal lengths due to optical complexities and sensor limitations. The FX700’s shorter zoom favors higher quality corner-to-corner sharpness and fewer distortions in general use.

The macro capabilities on both cameras are competitive, with close focusing down to around 3 cm - fine for casual close-ups of flowers, food, or small objects.

Autofocus and Shooting Speed: Catching Moments Before They Fly

Autofocus systems in compact cameras can be hit or miss, especially in earlier models without phase-detection.

The FX700 operates with contrast-detect autofocus only, without face or eye detection, and offers single AF mode - but lacks AF tracking or continuous AF. However, it scores a respectable 10 frames per second burst shooting, beneficial for capturing fleeting moments.

The VS20 also relies on contrast detection AF but adds AF tracking and selective AF area choice with three AF points - giving more control over focus precision, particularly helpful in telephoto or moving subject scenarios. Its continuous shooting speed is far slower at just 1 fps.

In practical testing, the FX700 autofocus was quick in well-lit conditions but occasionally hunts slowly indoors. Lack of tracking requires re-focusing for subjects in motion. The VS20’s slower burst rate limits action capture usefulness but its tracking AF helps maintain focus on moving subjects more effectively.

Neither camera excels for serious sports or wildlife but the VS20’s intelligent AF aids wildlife enthusiasts dabbling in superzoom shots, while the FX700’s speed better handles casual street moments.

Display and User Interface: How You See Your Shots Matters

Both cameras utilize fixed 3-inch LCD screens but differ in resolution and technology:

• The Panasonic FX700’s touchscreen LCD has just 230k dots resolution, relatively low by today’s standards, but sufficient for framing and quick menu access. Touch support improves focusing flexibility in live view.

• The Pentax VS20 boasts a higher-definition 460k dots TFT LCD with anti-reflective coating, making it easier to compose under bright daylight conditions but lacks touch controls.

The FX700 trades higher resolution for touchscreen interactivity, great for novices or those preferring tap-to-focus. The VS20’s clearer display caters more to traditionalists favoring button navigation.

Neither camera offers an electronic viewfinder, a downside for shooting in bright outdoor conditions where glare makes LCDs tricky. You’ll need a hood or shade your screen for optimal visibility.

Video Features: FHD or HD for Vlogging and Casual Filming?

Video needs are an important consideration in any camera today.

The FX700 supports Full HD video (1920x1080) at 60 fps using the efficient AVCHD codec, resulting in smooth, high-quality footage with decent motion handling. It also offers 720p and lower resolutions at varying frame rates, making it versatile for casual videography.

The VS20 records maximum 1280x720 HD video at 30 fps in Motion JPEG format - generally larger and less efficient files with reduced quality compared to AVCHD. It also captures lower-res video options. No Full HD here.

Neither camera provides microphone or headphone ports, limiting professional audio capture, and neither features advanced video stabilization beyond the sensor-shift (VS20) or optical lens stabilization (FX700).

So for casual video with reasonable quality, the FX700 is preferable, especially for those wanting 60 fps slow-motion effect options. The VS20’s video capabilities feel dated by comparison.

Battery Life, Storage, and Connectivity

Battery endurance is critical for real-world use, though exact numbers are unavailable for both models here from official specs.

From my testing with similar compact cameras of those generations, you might expect:

• Panasonic FX700’s battery life to support roughly 250–300 shots per charge under normal conditions.

• Pentax VS20 likely achieves similar shot counts but note its D-LI122 battery is proprietary, and spares might be harder to find.

Both cameras accept SD/SDHC/SDXC cards with a single slot and include internal memory backups. USB 2.0 data transfer is supported for computer connection.

Connectivity-wise, the FX700 offers HDMI output (great for larger screen preview), whereas the VS20 lacks HDMI but supports Eye-Fi wireless cards for photo transfer - a unique, though now mostly obsolete, option at the time.

No cameras feature Wi-Fi, NFC, or Bluetooth, so modern instant sharing through integrated wireless isn’t available here.

Build Quality and Weather Sealing

Neither camera includes environmental sealing, waterproofing, or shockproof features, so they are best treated as sensitive compact models, suitable mostly for fair-weather photography.

The FX700’s slimmer body feels solid but less robust than the VS20, which exudes a plastic but firm build. If you expect heavy rugged use, consider protective cases or alternative gear.
