Panasonic Lumix ZR1 vs Sony Cyber-shot W620: A Detailed Small Sensor Compact Camera Comparison

When it comes to small sensor compact cameras, the market offers many affordable options that cater primarily to casual shooters and entry-level users. However, even within this category, the differences in performance, ergonomics, and capabilities can be stark - differences that experienced photographers and enthusiasts will appreciate. In this hands-on comparison, I put two notable contenders head-to-head: the Panasonic Lumix DMC-ZR1 (henceforth Panasonic ZR1) and the Sony Cyber-shot DSC-W620 (Sony W620). Released roughly three years apart, these cameras represent different philosophies in ultra-portable imaging from their respective brands.

Drawing on extensive real-world testing and technical analysis, I dissect their strengths and limitations with an eye toward practical photography applications - from portraits to landscapes, wildlife to street shooting, and video work. Whether you’re a beginner exploring your options or a seasoned enthusiast needing a lightweight travel camera, this detailed review will help you understand what these two compacts really offer and which might suit your creative goals.

Design and Ergonomics: How They Feel in Your Hand

Starting with physical dimensions and ergonomics often tells you a lot about a camera's intended use. Both the Panasonic ZR1 and Sony W620 are compact point-and-shoots designed for portability.

• Panasonic ZR1: Measures 98x55x26 mm and weighs 158 grams. The slightly chunkier build gives it a secure grip, even for small hands. Panasonic opts for a simple but sturdy plastic chassis. Buttons are easy to locate, though not illuminated. The 2.7" fixed LCD screen is bright but low-resolution at 230k dots.

• Sony W620: Smaller and lighter at 98x56x20 mm and just 116 grams, this model prioritizes compactness, making it pocket-friendly for long outings. It features a similar 2.7" display, but Sony’s Clear Photo TFT LCD delivers a crisper viewing experience.

In my testing, the Panasonic’s extra heft translates to better one-handed handling and fewer accidental slips - especially when zooming or steadying shots. The Sony feels more like a wallet-friendly snapshot device you’d carry everywhere, but it also means a smaller grip and less substantial controls.

Ergonomics takeaway:
If handheld comfort during longer shooting sessions is important - for travel or casual street photography - Panasonic’s ZR1 has an edge. The Sony’s smaller footprint suits those who want the lightest camera to slip into a pocket.

Control Layout and Interface: How You Interact with Your Camera

A great camera is not just about specs; the user interface plays a vital role in your creative workflow. Both models lack manual exposure modes and focus primarily on ease of use.

• Panasonic ZR1: Features a round mode dial on top, though options are very limited (no aperture or shutter priority). The zoom toggle is well placed, and there's a dedicated playback button. The interface is simple, relying on menus accessed via directional input, with no touchscreen or live exposure preview.

• Sony W620: Sony strips down further, using fewer buttons and relying heavily on on-screen menus. The zoom and shutter controls are close but small. While the camera does support face detection autofocus, the overall control scheme is minimal.

Neither camera offers customizable buttons or advanced control layout - expected given their entry-level placement. However, the Panasonic’s physical controls afford quicker, more confident handling, especially when framing moving subjects.

Interface takeaway:
If you prioritize speed and simplicity over depth, the Panasonic wins. The Sony is streamlined but occasionally frustrating due to its pared-down controls.

Sensor Specs and Image Quality: What’s Inside Matters Most

At the heart of any camera is the sensor and image processing engine. Both these compacts use the common 1/2.3" type CCD sensor, a small format typical for point-and-shoot cameras but far behind APS-C or Micro Four Thirds in size and image quality potential.

• Panasonic ZR1: 12 megapixels resolution, CCD sensor, paired with Panasonic’s Venus Engine V processor. ISO sensitivity ranges from 80 to 6400, though noise grows quickly beyond ISO 400. No RAW capture is available - images are compressed JPEGs.

• Sony W620: Slightly higher resolution at 14 megapixels, also a CCD sensor, processed by Sony’s BIONZ chip. ISO goes up to 3200. It too lacks RAW support, limiting post-processing flexibility.

Image quality testing revealed:
Both cameras perform similarly in good light, delivering sharp images with reasonable color rendition. Panasonic tends to handle saturation a bit more naturally, while Sony images can appear slightly over-processed with boosted contrast.

Low light is where these cameras show their sensor size limitations. Panasonic’s higher max ISO helps, but noise control is poor above ISO 400. Sony’s max ISO is lower but delivers comparable results. Neither camera can rival modern sensor technologies here.

The fixed 1/2.3" sensor means dynamic range is limited - shadows clip quickly and highlights blow out in strong sunlight, particularly on sunny landscapes or high-contrast portraits.

Image quality takeaway:
These cameras suffice for snapshots and casual use but fall short for enthusiasts seeking high detail, low noise, or creative post-processing capability.

Display and Live View: Framing Your Shot with Confidence

Both cameras offer a 2.7" fixed LCD but no electronic viewfinders - a common trade-off in compact cameras aiming for slimness.

• Panasonic's LCD is serviceable but exhibits glare and limited resolution.
• Sony’s Clear Photo TFT improves visibility, especially in daylight and varied lighting.

Neither display has touchscreen capability, meaning menu navigation can feel dated. Neither offers live histogram overlays, grid lines, or focus peaking, making precise composition and exposure estimation more challenging.

Display takeaway:
Sony has a slight advantage here with a clearer screen but overall, both cameras demand user attention to framing technique and shooting conditions.

Autofocus System: Speed, Accuracy, and Usability

Autofocus (AF) performance is critical for capturing sharp images, especially for moving subjects or dynamic environments.

• Panasonic ZR1: Employs contrast-detection autofocus with 11 focus points. No face or eye detection autofocus is available. AF speed is slow compared to modern standards, with noticeable lag in low light or macro range. No continuous AF tracking or manual focus option.

• Sony W620: Also uses contrast detection but includes face detection and a basic AF tracking mode. However, focusing remains tentative and prone to hunt under challenging conditions. AF points information is not disclosed but multi-area focusing is supported.

In real-world use, both are underpowered for fast action or wildlife photography - the ZR1 is marginally more responsive thanks to its slightly newer processor architecture, but neither camera would satisfy a sports shooter.

AF takeaway:
For simple daylight scenes or stationary subjects, autofocus works adequately. For anything requiring speed or precision, neither camera excels.
