Pentax RZ10 vs Sony W800: Budget Compacts Under the Microscope

When you're hunting for an affordable point-and-shoot digital camera, there’s a dizzying array of options, even among older models. Today, I’m diving into a detailed face-off between two small sensor compacts: the Pentax Optio RZ10 (released in 2011) and the Sony Cyber-shot DSC-W800 (landed in 2014). Both promise simplicity and portability with modest feature sets, but as someone who’s tested thousands of cameras over 15 years, I’ll guide you through a practical, no-nonsense comparison so you can decide which deserves a spot in your camera bag.

First Impressions: Size, Handling, and Build

Let’s start with the tactile stuff, often overlooked but crucial to everyday use.

Pentax RZ10

• Dimensions: 97 x 61 x 33 mm
• Weight: 178 grams
• Environmental sealing: Yes (dust and splash resistant)

I have to tip my hat to Pentax on the RZ10’s construction. For such an affordable compact, the RZ10 boasts a sturdy build and weather resistance, uncommon in cameras at this price. Its slightly chunky body affords a decent grip, making it more comfortable for prolonged shooting than many point-and-shoots.

Sony W800

• Dimensions: 97 x 55 x 21 mm
• Weight: 125 grams
• Environmental sealing: None

The W800 is noticeably sleeker and lighter, which will appeal to cheapskates who value ultra portability and discretion. However, the slimmer form factor sacrifices some robustness and grip security. There’s no weather sealing, so rough outdoor conditions might pose a risk.

Overall, the RZ10 feels like a mini tank with some protection against the elements, whereas the W800 is lightweight and far less intimidating to slide into tight pockets.

A Peek at the Controls: User Interface and Handling

Both cameras lean heavily on automatic modes with minimal manual controls. Neither offers aperture or shutter priority, and manual focus is absent on the W800 and minimally implemented on the RZ10. So, if you’re a budding photographer itching for creative control, these aren’t your cameras.

The Pentax RZ10, however, provides a manual focus option - a rare feature in this segment - which can be helpful for macro shots or tricky lighting. The Sony W800 is fully fixed-focus with no manual override.

Control layouts on both remain simple, dominated by a 4-way directional pad and mode dial. The lack of illuminated buttons or physical dials means you’ll navigate menus often, which slows operation if you’re in a hurry.

Pixel Peeping: Sensor Technology and Image Quality

Both cameras employ small 1/2.3” CCD sensors typical of budget compacts, but their resolutions differ:

• Pentax RZ10: 14 megapixels (4288 x 3216)
• Sony W800: 20 megapixels (5152 x 3864)

While the Sony’s higher megapixel count sounds attractive, pixel density becomes a double-edged sword on such tiny sensors. More pixels packed into a small sensor means each photosite is smaller and gathers less light, which often results in noisier images in low light and less dynamic range.

From my lab testing and on-the-street shooting, both cameras deliver serviceable daylight images - but the RZ10’s lower resolution means slightly cleaner files with less noise at ISO 200 and above. Neither supports RAW capture, keeping you locked into JPEGs, which limits post-processing flexibility.

Color rendering favors the Sony slightly thanks to more vibrant color profiles and superior white balance adjustment options. However, the Pentax’s CCD sensor tends to produce more natural skin tones, a boon if portrait work is your main focus.

Screen & Viewfinder: How You Frame Things Matters

Both cameras feature fixed 2.7-inch TFT LCDs at a modest 230k-dot resolution, sufficient but uninspiring. Neither has a built-in viewfinder - no optical and no electronic.

In bright daylight, reflections and viewing angles are challenging on both. The Pentax applies an anti-reflective coating which makes it marginally easier to compose shots outdoors, whereas the Sony’s screen can feel washed out. Given the lack of eye-level composing options, you’ll end up holding the cameras away from your face and squinting in strong sunlight.

Neither offers touch input, so navigating settings is button-based.

Autofocus and Speed: Sharpness in Action

Pentax RZ10

• Focus system: Contrast detection, 9 areas, center weighted, no face detection
• AF speed: Moderate lag, single-shot AF only

Sony W800

• Focus system: Contrast detection, unknown points, face detection supported
• AF speed: Slightly faster and more responsive, single-shot AF only

Neither camera sports continuous autofocus or tracking for moving subjects, and burst rates max out at a sluggish 1 fps. For action or wildlife, you’ll be frustrated.

However, Sony edges out slightly in autofocus accuracy thanks to face detection, which improves portraits and helps in street photography. The Pentax’s AF can struggle to lock in low contrast or dim scenes.

Zooming In: Lenses and Versatility

The fixed lens focal ranges are:

• Pentax RZ10: 28–280 mm equivalent (10x zoom), f/3.2–5.9 aperture
• Sony W800: 26–130 mm equivalent (5x zoom), f/3.2–6.4 aperture

The Pentax’s 10x zoom leaps out as a clear winner for telephoto reach, essential for wildlife, sports, or distant travel shots. Its macro focus distance of 1cm also lets you get impressively close to subjects for detailed close-ups.

The Sony sticks to a more modest zoom range, better suited to general snapshots, landscapes, and portraits. It misses explicit macro mode details, so don’t expect close-up miracles.

Optical image stabilization is sensor-shift-based on the Pentax and optical on the Sony. Both help tame camera shake, but the Pentax’s combination with a longer zoom range warrants extra respect.

Picture This: Sample Image Quality Illustrated

To get a real-world sense of how these cameras perform, I compared sample images under varied conditions.

Key observations:

• Portraits: The RZ10 renders more natural skin tones despite softer detail; the W800 offers slightly punchier colors with noticeable processing.
• Landscapes: The Sony’s higher resolution reveals subtle textures, but highlight clipping is more evident; the Pentax preserves dynamic range better.
• Low light: Both produce noisy, grainy images at ISO 800+, but the RZ10 maintains cleaner shadows.
• Macro: The Pentax excels with sharp close-ups and background blur.
• Zoomed shots: Pentax dominates telephoto reach, with decent clarity; Sony’s telephoto is weaker and soft at the long end.

Shooting in the Wild: Use Case by Use Case

Let’s break down how these cameras stack up for popular photography styles.

Portrait Photography

The Pentax RZ10’s superior skin tone accuracy and manual focus option make it slightly more appealing for portraits, especially if you want some control over focusing for close-ups. The lack of face detection can pose a challenge though.

Sony’s face detection AF is helpful, but skin tones can appear a bit artificial. Shallow depth of field is limited on both due to tiny sensors and lens apertures.

Landscape Photography

Both cameras deliver acceptable detail for casual landscapes, but the Pentax’s wider zoom and better dynamic range will please those who love sweeping vistas. The Sony’s higher resolution sensor shows more texture but at the cost of highlight clipping.

Pentax’s weather sealing also lets you venture out worry-free in light mist, unlike the Sony.

Wildlife Photography

Pentax is the definite choice here - its 10x zoom lens allows you to bring distant critters closer. AF speed and burst rates are poor on both, so patience is key.

Sony’s telephoto is too short for serious wildlife shooting.

Sports Photography

Neither camera is designed for sports. The single-shot autofocus with no continuous tracking and 1 fps burst rate won't freeze fast action. Pentax’s longer zoom helps frame wider field shots better.

Street Photography

Sony’s slimness and light weight make it easier to carry discreetly for street snaps. Better face detection aids focusing on people spontaneously.

Pentax feels bulkier but offers more control for macro street details.

Macro Photography

Pentax RZ10 shines with 1cm macro focus, allowing stunning close-ups with background separation. Sony lacks specific macro capabilities.

Night and Astro Photography

Don’t expect miracles from either. Small sensors and compressed JPEG-only files limit noise control. The Pentax’s lower base ISO helps, but exposures max out at 2 seconds on Sony and 4 seconds on Pentax - too short for star trails.

Video Capabilities

Both record HD 720p video at 30 fps, but files are heavily compressed (Motion JPEG on Pentax, MPEG4 on Sony). No microphone or headphone jacks on either.

Pentax records at 15 and 30 fps in multiple resolutions, Sony sticks to 30 fps. Neither offers image stabilization during video, so handheld clips tend to be shaky.

Travel Photography

Pentax’s durability, longer zoom, and macro focus make it a versatile travel companion for varied shooting situations.

Sony’s lightweight profile and simplicity suit casual travelers focused on snapshots with less bulk.

Professional Work

Neither camera supports RAW capture or advanced file formats, falling short for professional workflows demanding flexibility and high image quality.

Pentax’s environmental sealing and manual focus are pluses but don’t compensate for sensor limitations.

The Sony presents amazing bang for the buck for absolute beginners who want a simple snapshot camera. The Pentax demands double the investment but gives better zoom, sturdiness, and modest creative control, making it a smarter buy for serious amateurs on a budget.

In the Trenches: Real-World Experience

After weeks carrying both cameras in various conditions - urban streets, parks, even a misty morning hike - I’m reminded that these cameras are designed not to outshoot your smartphone but to give a simple point-and-shoot experience backed by optical zoom.

The Pentax RZ10's manual focus and impressive zoom made me pull it out for macro florals and distant wildlife. It felt more substantial in hand and handled rougher weather without worry. The lack of RAW hurts the enthusiast side, but at this price, it’s forgivable.

The Sony W800 was a purse-friendly companion, great for quick snaps at parties and city strolls. Face detection is a fantastic perk for portraits, and lightweight build meant I didn't mind carrying it all day. Image quality is acceptable, but scenes with mixed lighting exposed clear limits.
