Sony G3 vs. Sony WX500: An In-Depth Comparison for the Practical Photographer

Sony’s Cyber-shot lineup has long been a versatile portfolio spanning compact point-and-shoots to travel zooms and superzooms. In this article, I’ll dive deep into two of their compact cameras from different eras and categories: the Sony Cyber-shot DSC-G3 (2009) and the Sony Cyber-shot DSC-WX500 (2015). Both aim to serve enthusiast photographers seeking a balance of portability and performance, but their distinct designs and feature sets put them at very different points on the capability spectrum.

Having extensively tested both cameras side by side over weeks - including real-world shooting in portrait, landscape, street, and travel scenarios - I’ll share insight into how their engineering choices translate into tangible photographic outcomes. Whether you’re shopping for a basic compact with decent optics or a versatile superzoom with subtle manual controls, this comparison will furnish you with grounded, experiential guidance.

A Tale of Two Compact Styles: Size, Handling, and Ergonomics

Anyone who’s held these cameras immediately notices the contrasting footprints and design intentions.

Sony G3: This is a classic late-2000s compact with a neat “slab” shape, slim bezels, and a modest profile measuring 97 x 59 x 22 mm and weighing a featherweight 185 g. It's tactile but not especially contoured, and - critically - it has a fixed lens with a limited zoom range. The lens barrel is flush with the body, making it pocket friendly but somewhat fragile in grip. There is no dedicated grip or stocky build - this camera is made to slip into a purse or coat pocket without fuss.

Sony WX500: Fast forward six years, and Sony has evolved an entirely different form factor focused on zoom versatility. The WX500, at 102 x 58 x 36 mm and 236 g, is chunkier and taller, largely due to its extensive 30x zoom lens (covering an equivalent 24-720mm focal range). The increased size affords better handholding stability especially at the telephoto end, despite lacking a dedicated thumb grip or textured rubbers. The back’s clean, practical button layout and tilting LCD add to usability.

Moving to top controls...

The WX500 offers more external control sophistication, including dedicated buttons for exposure compensation, ISO adjustments, and shooting modes - vital when working in fast-paced street or travel shooting situations. The G3 feels more button-lite and consumer-oriented, with fewer physical dials and reliance on menus for features, reflecting its pre-smartphone-era simplicity.

Overall, ergonomics on the WX500 skew towards enthusiast shooters who want manual control on the go; the G3 prefers ease and lightness.

Sensor and Image Quality: The Heart of the Matter

Beneath the lens is where the most significant disparities lie - and where years of sensor tech advancements come into play.

Both cameras share a sensor size of 1/2.3", typical for small sensor compacts, with dimensions 6.17 x 4.55 mm, covering an area of approximately 28.1 mm². But that’s where commonality ends.

• Sony G3 employs a 10-megapixel CCD sensor - standard for the era, optimized for relatively low ISO use (max native ISO 3200 but with significant noise beyond ISO 400). CCD sensors are renowned for relatively good color rendition in controlled lighting but tend to lag behind CMOS sensors in sensitivity and noise control.

• Sony WX500 features a more modern 18-megapixel BSI CMOS sensor coupled with the BIONZ X image processor. This combination delivers higher resolution images (4896x3672 pixels) and greatly improved dynamic range and low-light sensitivity. The WX500 stretches ISO capabilities up to 12800 native, offering usable results at ISO 800 to 1600, which were unattainable for the G3.

Practically, this means that the WX500 can capture sharper, more detailed images with less noise - making it more well-rounded for varied lighting scenarios, including indoors and dusk.

Neither camera shoots in RAW, which is a considerable limitation for advanced post-processing workflows. However, Sony’s JPEG engine in the WX500 is significantly more adept, with customizable white balance, picture profiles, and noise reduction.

Viewing and User Interface: Screen and Composition Experience

An often overlooked but crucial aspect for day-to-day shooting is how you interact with a camera’s display for composition and settings review.

Sony G3: The G3 sports a large 3.5-inch fixed LCD with a respectable 921k-dot resolution. While generous in size for its day, it’s a touch screen - novel when launched - but the touchscreen implementation was limited and not very responsive by modern standards. No articulating function or viewfinder compels reliance on the LCD alone, which can be tricky in bright sunlight.

Sony WX500: The WX500’s 3.0-inch screen measures smaller but matches the resolution digitally at 921k dots. Its defining feature is the tilting mechanism - up to 180 degrees upward for flexible framing, especially selfies or low angle shots. Although not touchscreen, the WX500’s physical buttons and clean menu navigation feel more polished and faster to access key functions.

Neither camera includes a built-in electronic viewfinder (EVF), which some users might miss for outdoor compositional precision. Both are screen-only shooters, emphasizing pocketability over studio control.

Lens and Zoom Ranges: From Standard Zoom to Superzoom

The optical design defines much of a camera’s creative usage. Here the gap is stark:

• Sony G3: Offers a 35-140 mm equivalent zoom range (4×) with maximum apertures ranging F3.5-10.0. This moderate telephoto reach offers some framing flexibility but feels limited if your subject is far away or you want wide environmental context.

• Sony WX500: A serious zoom powerhouse - covering 24-720 mm equivalent (30×), the WX500 can shoot ultra wide landscapes (24 mm) and dive deep into wildlife or architectural details at 720 mm. Aperture ranges F3.5-6.4 are relatively bright at the wide end but close down substantially at telephoto lengths.

The WX500’s lens versatility makes it ideal for travel, wildlife, and sports snapshots where you seldom want to switch lenses. The optical image stabilization (OIS) on both cameras aids sharpness, but it's especially critical on the WX500 given the long reach prone to handshake blur.

Neither lens features a filter thread due to the compact design, limiting some accessory options.

Autofocus and Shooting Performance: Precision and Speed Matters

Day-to-day usability often hinges on autofocus (AF) responsiveness and reliability - especially with moving subjects.

• Sony G3 relies on contrast-detection autofocus with 9 focus points. It supports single AF but no continuous AF or tracking. The AF tends to hunt appreciably in low light or when subjects move, making it more suited for static scenes - think landscapes or posed portraits. Face detection is absent, making accurate autofocus on human subjects a hit-or-miss affair.

• Sony WX500 steps up with enhanced contrast AF plus face detection and continuous AF tracking, alongside selective AF area choices. It supports continuous shooting up to 10 fps, giving it a decisive edge for action photography and street shooting. While not a pro-level AF system, it’s commendably capable for the class.

The WX500’s faster max shutter speed of 1/2000 sec (vs. G3’s 1/1000 sec) helps freeze motion better in bright conditions. Its shutter priority, aperture priority, and manual exposure modes allow photographers to creatively control depth of field and motion blur - functionality the G3 reserves for auto-only exposure.

Real-World Photography Scenarios: Who Excels Where?

Let’s break down both cameras’ likely user benefits by photography genre.

Portrait Photography

For portraits, accurate skin tones, smooth bokeh, and quick eye detection AF are key.

• The G3’s CCD sensor renders pleasing color tones in controlled lighting but struggles with focus precision and lacks face/eye AF. The limited zoom range also restricts your ability to compress backgrounds (ideal for flattering portraits).
• The WX500’s higher resolution sensor, face detection AF, and longer zoom zoom allow tighter framing and better subject isolation. While its smaller sensor size limits bokeh quality compared to larger-sensor cameras, it still produces better portraits in general.

Verdict: WX500 is the smarter choice for casual portraiture demanding reliable focus and framing flexibility.

Landscape Photography

Landscape shooters prize resolution, dynamic range, and weather sealing.

• Both share the same sensor size, but the WX500’s newer sensor delivers somewhat better DR and higher pixel count.
• Neither camera offers weather sealing.
• WX500’s wider 24mm lens is ideal for sweeping vistas - G3 starts too tight at 35mm.

Verdict: WX500 pulls ahead thanks to wider optical range and improved sensor performance.

Wildlife and Sports Photography

These genres depend heavily on autofocus speed, burst performance, and telephoto reach.

• The G3 is simply not built for action - slow 2 fps burst, no AF tracking, and limited zoom make it ineffective here.
• The WX500’s 10 fps burst, AF tracking, and 720mm reach lets you capture distant subjects effectively, though AF speed lags behind mirrorless/sports DSLRs.

Verdict: WX500 is usable for casual wildlife and sports snaps; G3 is not.

Street Photography

Street photography demands discretion, portability, and decent low light capability.

• The G3 shines in compactness and quiet operation but lacks manual controls and struggles in low light.
• The WX500 is slightly larger but still pocketable, offers manual modes, and outperforms the G3 in autofocus and ISO range for dim urban scenes.

Verdict: WX500 favored for versatility; G3 for ultra-minimalist carry.

Macro Photography

Close-up precision requires good minimum focus distance and precise AF.

• G3 has no specific macro focus range.
• WX500 offers 5 cm macro focusing, enabling detailed close-ups of flowers or insects.

Verdict: WX500 supports macro work better.

Night and Astrophotography

High ISO performance and long exposure controls are the key here.

• G3 max shutter speed is 1 sec (not optimal for long exposures), and high noise at ISO >400 limits night work.
• WX500 offers shutter up to 30 sec, higher ISOs, exposure compensation, and RAW support absence notwithstanding, it’s the better low-light tool.

Verdict: WX500 better for night scenes by a significant margin.

Video Capabilities

Both cameras provide basic video options.

• G3 max video is 640x480 at 30fps (standard definition), motion JPEG codec - obsolete by today’s standards.
• WX500 supports Full HD 1080p up to 60 fps, uses modern AVCHD and XAVC-S codecs, and built-in optical image stabilization smooths handheld footage nicely.

Neither have microphone/headphone ports or 4K video. The WX500 stands out for casual high-quality video.

Travel Photography

Travelling demands versatility, battery life, and ease of use.

• The G3’s ultra light build and slim profile make it an easy pack-in. However, limited zoom and manual options may quickly frustrate.
• The WX500’s superzoom lens covers most shooting scenarios. Its improved battery life (~360 shots) and wireless connectivity (NFC) provide useful on-travel conveniences like image transfer.

Verdict: WX500’s flexibility trumps the G3’s compactness for most travellers.

Professional Use

For workflow integration and reliability...

• Neither camera offers RAW or tethering. Both lack professional-grade environmental sealing or modular options.
• The WX500 offers more manual control and better output for casual professional use like events or documenting, but serious pros will look elsewhere.

Build Quality and Durability: How Rugged?

Neither the G3 nor WX500 claims weather sealing, dustproofing, or shockproofing. Both cameras are everyday compacts designed for gentle handling rather than harsh environments. The WX500’s slightly more robust frame and lens barrel trailing edge grip feels more resilient, but neither is suitable for rugged professional use without extra care.

Connectivity and Storage

The WX500 holds a clear edge in connectivity:

• The G3 only offers USB 2.0 and HDMI; no wireless or Bluetooth.
• The WX500 adds NFC for streamlined sharing and remote control via a smartphone app, easing post-shoot workflows.

Both accept a single memory card slot. The G3 uses Sony’s proprietary Memory Stick Duo format, which is less common and more constricted, whereas the WX500 supports Memory Stick Duo plus SD/SDHC/SDXC cards - far more accessible today.

Battery Life and Practical Shooting Duration

Sony rates the WX500 at roughly 360 shots per charge (CIPA), which is average for these compacts but sufficient for a day out. The G3’s battery life data is not well documented, but anecdotal experience shows it is significantly shorter, partly due to older battery tech and reliance on the rear LCD without power-saving options.

Price-to-Performance: Which Camera is the Best Bang for Your Buck?

• The G3 can be found used or refurbished around ~$200, reflecting its age and entry-level specs.
• The WX500 currently sells for around $350 new or less used, representing a reasonable mid-tier compact superzoom.

Given the superior photographic versatility, image quality, and features, the WX500 offers significantly better value for the price despite the higher cost. The only niche for the G3 is ultra-lightweight casual shooting and budget-constrained buyers not requiring modern capabilities.

Evaluating the Cameras: Scores and Genre Strengths

To help clarify overall and genre-specific performance, I compiled and calibrated evaluation scores based on pixel-level testing, feature analysis, and field shooting with both cameras.

As visible, the WX500 dominates across virtually every category, except for raw compact size and ultra-simple operation where the G3 retains a minimal lead.

Sample Images: Side by Side Visuals

To put this into perspective, here are some carefully curated JPEG images, taken under matched conditions:
