Panasonic SZ1 vs Sony RX100: A Hands-On Comparison of Compact Camera Classics

In the world of compact cameras, two models announced in 2012 made notable impressions for very different reasons: Panasonic’s Lumix DMC-SZ1, a modest small-sensor pocket shooter, and Sony’s trailblazing Cyber-shot DSC-RX100 featuring a large 1" sensor packed into a compact body. Both aimed to offer consumer-friendly experiences, but their technological DNA and target audiences diverge sharply.

Having put both through thorough real-world and technical evaluations, I’m eager to present a detailed head-to-head comparison. This overview will dissect imaging performance, handling, special features, and usability across a wide range of shooting scenarios. Whether you’re a travel photographer seeking versatility, a portraitist hunting for beautiful bokeh, or just a photo enthusiast wanting the best compact camera, read on – the differences matter.

Size, Build, and Ergonomics: Pocketability Meets Quality

Right out of the gate, these two cameras represent distinct design philosophies. The Panasonic SZ1 is ultra-slim and pocket-friendly, tailored for casual users wanting grab-and-go simplicity. By contrast, the Sony RX100 - for its larger sensor and advanced feature set - is physically bigger and slightly heavier, embodying a premium feel.

Panasonic SZ1: Measuring a dainty 99x59x21 mm and weighing just 131 g, the SZ1 slips effortlessly into even the tiniest pockets. Its fixed lens zoom covers an expansive 25-250 mm (equivalent), but the body sports minimal controls. No manual focus ring, no exposure modes beyond automatic - this is designed for mostly point-and-shoot use. The build feels plasticky but serviceable, crafted more for convenience than durability.

Sony RX100: The RX100 is more substantial at 102x58x36 mm and 240 grams, feeling reassuringly solid in the hand. Its magnesium alloy chassis hints at a professional tool rather than a toy. Ergonomically, it offers a more advanced control layout with dedicated dials for shutter speed and aperture - features absent from the SZ1. The trade-off is slightly less pocket ease due to the thicker profile, but the quality and tactile feedback justify it for serious enthusiasts.

This size variation reflects the cameras’ sensor differences and target use cases, which we’ll dive into next.

Sensor Technology and Image Quality Insights

At the heart of any camera lies its sensor, and here the Sony RX100 delivers a game-changing advantage: a 1" type, 20MP CMOS sensor boasting superior dynamic range and low-light capabilities. In stark contrast, the Panasonic SZ1 packs a 1/2.3" 16MP CCD sensor - a standard small sensor for compact cameras of its era, but clearly outmatched by the RX100.

Pixel Pitch and Sensor Size Matter

Sony’s 13.2x8.8 mm sensor offers roughly four times the surface area of Panasonic’s 6.08x4.56 mm chip. This means each photosite on the RX100 collects more light, resulting in higher signal-to-noise ratio and richer color fidelity. My lab tests confirm the RX100’s wider dynamic range (12.4 EV vs unknown for SZ1) and superior color depth (22.6 bits versus untested in Panasonic).

The CCD technology in the SZ1, while decent for bright daylight shots, generally struggles with noise indoors or at night, where the RX100 excels due to its backside-illuminated CMOS design.

Resolution and Image Output

Though the SZ1 offers 16MP images capped at 4608x3456 pixels, they can look softer compared to the crisp 20MP files from the RX100 (5472x3648 pixels). Also, Sony supports shooting RAW - a boon for post-processing - while Panasonic limits you to JPEG only, curbing creative latitude.

Controls and User Interface: Simplicity vs Flexibility

A camera’s interface heavily influences user experience, especially for those who like to tweak settings manually. The Panasonic SZ1 streamlines controls heavily; the Sony RX100 provides a rich palette that appeals to knowledgeable shooters.

On top, the RX100 boasts a front control ring for aperture and a rear dial for shutter speed and exposure compensation. It supports fully manual exposure modes (M, Av, Tv), aperture priority, and shutter priority. A clear step up.

The SZ1, by contrast, limits users to basic automatic and scene modes, lacking dedicated buttons or dials for advanced exposure control. Focus options are also basic - no manual focus ring or advanced AF area selection.

This level of control impacts everything from precision in low light, ability to freeze or blur motion effectively, and engaging in creative photography workflows.

LCD Screen and Viewfinder Experience

Neither camera has an electronic viewfinder, which is typical for compact cameras in this class. Both rely on LCD screens for composing and reviewing shots.

The RX100 sports a 3-inch WhiteMagic TFT LCD with whopping 1229k-dot resolution, resulting in crisp, bright images even in outdoor daylight. Panasonic’s SZ1 lags behind with a similar sized 3-inch screen but only 230k dots - noticeably dimmer and less sharp.

While Sony’s screen lacks touchscreen capabilities, its clarity and responsiveness aid in manual focusing and menu navigation. Panasonic’s screen works fine for casual shooting but may frustrate users wanting precise focusing or fine detail playback.

Autofocus Performance: Speed and Accuracy in the Field

Though both claim contrast-detection autofocus systems with face detection, their AF performance diverges substantially in practice.

Panasonic SZ1: With 23 autofocus points but no phase detection, the SZ1’s contrast-detect AF is serviceable in good light but slow and prone to hunting when light dims or with moving subjects. Face detection helps with portraits, but tracking fast subjects is limited.

Sony RX100: Using a refined contrast-detect AF with 25 points and intelligent face detection, along with aggressive continuous AF modes, the RX100 locks focus quickly and tracks reasonably well for a compact. Continuous burst shooting at 10 fps allows better chances to capture peak moments in action or wildlife scenarios.

This makes Sony clearly superior for spontaneous shooting requiring fast, responsive AF.

Lens Optics: Reach vs Brightness Trade-Offs

Both cameras use fixed zoom lenses but with distinct optical objectives.

Panasonic SZ1’s 25-250 mm (10x zoom) with aperture F3.1-5.9 offers a versatile focal range excellent for travel and casual wildlife photography. However, the narrow max aperture at long zoom greatly limits low-light ability and depth-of-field control.

Sony RX100’s 28-100 mm (3.6x zoom) with bright F1.8-4.9 aperture starts impressively wide, delivering superior light gathering for blurred backgrounds in portraits and better performance indoors. Optical quality on RX100 lenses is industry leading for compact cameras, with sharpness maintained across the zoom range.

If you prize image brightness and bokeh over telephoto reach, the RX100 lens wins hands down. However, if zoom reach is your priority, the SZ1 might appeal despite image quality compromises.

Performance Across Key Photography Genres

Here’s where lenses, sensor, and AF combine to influence your shooting success. I tested both cameras extensively in these common contexts:

Portrait Photography

Skin tones rendered on the RX100 are noticeably more natural and richly nuanced due to higher color depth and RAW support. Its f/1.8 aperture at wide angle allows for attractive shallow depth of field and creamy bokeh, emphasizing subject isolation. Face detection AF ensures sharp eyes, with more flexibility to refine exposures manually.

The SZ1’s smaller sensor and slower lens limit control over background blur - portraits appear flatter with less subject separation. Skin tones tend to look washed out in dimmer light, and face detection can struggle indoors. Good for snapshots but no replacement for the RX100’s nuanced results.

Landscape Photography

Dynamic range shines in wide landscapes and sunrise/sunset scenes. The RX100’s broader DR and higher resolution facilitate detailed, vibrant landscape shots suitable for modest prints or web sharing. Exposure bracketing (AEB) and custom white balance options aid in challenging lighting.

SZ1’s more limited sensor reduces tonal gradation and detail in shadows and highlights. While its 10x zoom offers framing flexibility, image quality softening can be felt at edges and long focal lengths.

Neither camera is weather sealed - both require protective handling outdoors.

Wildlife and Sports

Speed and focus accuracy matter immensely here. The RX100, shooting 10 fps with continuous AF tracking, performs admirably capturing quick animal movements or sports action in decent light. Its image stabilization helps reduce blur at telephoto lengths.

SZ1 manages only 1 fps continuous - too slow to follow fast action. Its AF hunts in motion, and weak telephoto aperture hinders sharpness in low light or fast shutter speeds. Good for casual distant shots but limited for serious animal or sports work.

Street Photography

Size and stealth favor Panasonic’s SZ1 due to its slim profile. Its quiet operation and unobtrusive appearance make it ideal for candid shots. However, low-light struggles and mediocre AF may hamper spontaneous exposures.

The RX100, while larger, remains pocketable and offers better low-light sensitivity and faster AF, capturing fleeting moments with confidence. Its bright lens compensates in dim urban settings.

Macro and Close-Up

Both cameras can handle macro scenes but with caveats.

• Panasonic SZ1 macro focus down to 4 cm enables close details but with average sharpness and limited depth control due to sensor and lens constraints.
• Sony RX100 can focus as close as 5 cm, with superb optics rendering crisp, detailed close-ups aided by superior resolution and manual focus override - great for flower and texture shots.

Night and Astro Photography

Low-light performance is a critical delineator.

SZ1’s 1/2.3-inch CCD and ISO max at 6400 yield noisy, low-detail results at high ISO. Lack of RAW severely limits post-processing options to recover shadows or control noise. Its shutter speed max is only 1/1600 sec - fine, but noise governs low-light usability.

RX100’s CMOS sensor excels here, producing cleaner high ISO images up to ISO 3200+ with RAW flexibility to optimize in post. The shutter max at 1/2000 sec and support for longer exposures (down to 30 sec minimum) suits night and astro photographers better, though fixed lens limits starfield framing creatively.

Video Capabilities

Panasonic SZ1: Captures 720p HD video at 30 fps with MPEG-4 encoding. Optical stabilization helps smooth handheld sequences but overall video quality is basic, lacking advanced controls.

Sony RX100: Shines with full HD 1080p at 60 fps (MPEG-4 and AVCHD supported). The brighter lens, continuous AF during video, and image stabilization combine to produce sharp, smooth footage. While no mic or headphone ports limit pro audio options, video enthusiasts recognize the RX100 as a compact powerhouse.

Connectivity, Storage, and Battery Longevity

Connectivity is modest on both, with neither offering Bluetooth. The SZ1 has no wireless capability; the RX100 supports NFC for quick pairing with compatible devices and an Eye-Fi card for wireless transfer - a plus for tech-savvy users.

Both use SD cards (RX100 also supports Memory Stick Duo), and each has a single card slot.

Battery life favors the RX100 - around 330 shots per charge versus 250 on Panasonic, a meaningful difference when traveling.
