Sony G3 vs. Sony TX9: A Detailed Comparison to Guide Your Next Camera Choice

When it comes to choosing a compact camera, enthusiasts and professionals often look beyond megapixels and marketing buzz. Real-world performance, sensor technology, handling, and versatility across photography styles matter deeply. In this hands-on comparison, I take you through a meticulous side-by-side examination of two distinct but often confused Sony Cyber-shot compacts - the Sony Cyber-shot DSC-G3 (G3) from early 2009 and the Sony Cyber-shot DSC-TX9 (TX9) introduced about 18 months later in mid-2010.

Having tested thousands of cameras over my 15+ years of reviewing, including compact cameras losing favor to smartphones, I sift through their details, usability, and image quality to reveal which camera works best for your needs - whether portraiture, wildlife snaps, sports shoots, or travel diaries.

Let’s dive in.

First Impressions: Size, Ergonomics & Handling

Despite being small-sensor point-and-shoots, these two cameras present contrasting design philosophies which immediately impact usability and comfort during shoots.

• Sony G3: This camera adopts a traditional compact camera shape at 97x59x22mm, weighing 185g. It feels solid with a slight heft that translates to stability in hand. The slightly chunkier frame makes gripping less fiddly, facilitating steadier shots - especially useful when holding still for macro or landscape work.

• Sony TX9: Ultra-compact and about as sleek as you can get at 98x60x18mm and just 149g, the TX9 is ideal for pocketability, slipping effortlessly into jackets or small bags. The lower weight, however, means you need to be mindful of grip stability - this slim profile tends toward less tactile feedback and may feel slippery over time.

Ergonomically, the G3’s thicker body eases extended handheld shooting. The TX9 prioritizes stylish compactness over long-session comfort. For photographers who shoot extensively, especially outdoors or on travel shoots, this difference is a crucial consideration.

Design Details & Control Layout

The arrangement of dials, buttons, and screens heavily influences workflow speed and shot-taking spontaneity.

• Sony G3: The G3’s top layout is pared-down with minimalist controls, reflecting its 2009 origins before the touchscreen craze fully took hold. There’s no dedicated manual exposure mode, and shutter/aperture priority options are absent. The control surface is modest but clear, with optical image stabilization and flash toggles reachable. Though lacking in complexity, it’s intuitive for casual shooting.

• Sony TX9: This model features a touchscreen interface, enhancing compositional flexibility and menu navigation, as typical for its time. The BIONZ image processor supports faster continuous shooting (up to 10fps vs. G3’s 2fps), beneficial for capturing action or fleeting moments. A slightly longer max shutter speed range (2 to 1600 vs. 1 to 1000) opens creative exposure possibilities.

The touchscreen is a double-edged sword; it streamlines menus but sacrifices physical feedback. Users accustomed to tactile controls may find it less precise during quick shots. However, for new users or street photography where discreet operation is paramount, the touchscreen responsiveness is advantageous.

Sensor Technology and Image Quality

Both cameras use a 1/2.3” sensor type, standard in compacts, but their sensor technologies differ significantly.

• Sony G3: Employs a CCD sensor with 10MP resolution. CCDs were common in its era for good color reproduction but lagged in noise control and dynamic range. The maximum ISO is 3200, but with significant noise creeping in past ISO 400. Images tend to have a softer look with less micro detail.

• Sony TX9: Introduces a BSI-CMOS sensor at 12MP resolution, offering better light gathering capability and improved noise handling. Although still small by mirrorless or DSLR standards, the TX9’s sensor delivers cleaner images at higher ISOs and improved dynamic range. This makes a noticeable difference in dim conditions or night shots.

From tests involving landscapes and low-light scenes, the TX9 gives crisper files with fewer artifacts, though the improvements are incremental given sensor size limitations of both cameras. Neither supports RAW output, which limits post-processing latitude significantly.

LCD Screen and User Interface

With no electronic viewfinders on either model, the rear LCD screens become critical for framing and reviewing shots.

• Both cameras feature 3.5-inch fixed LCDs with resolutions around 921-922k dots, a generous size for easy framing.

• The TX9’s touchscreen adds an interactive layer missing from the G3, including touch-to-focus and on-screen menu adjustments. This complements live view shooting with advantages in street and casual settings.

• The G3's screen is standard, non-touch, adequate for reviewing but slower to navigate settings due to button reliance.

If you value fast, intuitive control shifts and touch focusing, the TX9 pulls ahead here. However, if you prefer straightforward tactile buttons and less screen-smudging, the G3’s simpler interface may appeal.

Autofocus System: Speed, Accuracy, and Flexibility

Autofocus capabilities can make or break candid, wildlife, and sports photography. Both models feature 9-point contrast-detect AF systems without phase detection, though with notable differences:

• Sony G3: Offers single-shot AF only, with no continuous AF option. This makes tracking moving subjects challenging. Face detection is absent, so portraits require careful focusing.

• Sony TX9: Adds AF tracking and center-weighted AF area modes, along with single-shot AF. While no face detection or animal eye AF is present, the tracking boosts reliability during dynamic shooting. Touch AF through the screen can also enhance precision.

In practice, I found the TX9 focuses faster and locks more consistently in daylight. The G3’s slower, more deliberate AF routine hampers capturing fast-moving subjects but suffices for landscapes and posed portraits.

Lens and Zoom Capabilities

Both cameras feature fixed zoom lenses scaled by a 5.8x focal length multiplier due to the small sensor size, with key distinctions:

• Sony G3: 35-140 mm equivalent focal range (4x zoom) with apertures from f/3.5 to f/10. The longer reach benefits occasional telephoto shots, but slow maximum aperture at tele end limits low light performance and bokeh.

• Sony TX9: Wider 25-100 mm equivalent (4x zoom) with faster maximum aperture range (f/3.5-4.6) allowing brighter wide-angle shots and enhanced background separation potential. Notably, the macro focus range is down to 1cm, excellent for close-up work.

While the G3’s telephoto extension aids sports or wildlife framing, the TX9’s wider wide-angle suits landscapes and interiors better, plus macro enthusiasts will appreciate its close focusing.

Image Stabilization and Flash Performance

• Both cameras feature optical image stabilization, crucial for steady handheld shots given the small aperture and sensor sizes.

• The G3’s flash has a longer effective range at 4.3 meters with red-eye reduction, multiple flash modes including slow sync, while the TX9 has a slightly shorter flash range at 3.8 meters.

In real-world use, stabilization on both cameras is effective for still subjects up to 1/10s shutter speeds. The TX9’s newer OSS system felt marginally improved in video stabilization and moderate zoom settings.

Continuous Shooting and Shutter Speed Range

Burst shooting and shutter speed ranges influence sports and action photography options.

• Sony G3: Maximum 2fps continuous shooting, shutter speed range 1/1000 to 1 second.

• Sony TX9: Much faster at 10fps burst with shutter range from 1/1600 to 1/2 seconds.

The higher burst rate on TX9 is a significant boon for capturing fleeting sports moments or wildlife behavior sequences. The broader shutter speed range allows more creative control in bright and dim lighting.

Video Capabilities: Quality and Formats

Video remains an essential feature in compact films:

• Sony G3: Offers VGA 640x480 resolution at 30fps in Motion JPEG format, a dated spec that quickly pales next to modern HD standards.

• Sony TX9: Captures Full HD 1920x1080 video at 50fps using AVCHD compression, delivering far superior image clarity and smoothness.

Neither camera has microphone or headphone jacks, limiting audio options. Video enthusiasts focusing on HD quality and smooth frame rates will clearly favor the TX9.

Battery Life and Storage

• Both accept proprietary batteries with proprietary chargers; TX9 uses NP-BN1 battery model.

• Memory slots: G3 uses Memory Stick Duo/Pro Duo exclusively, while TX9 is more versatile, supporting SD/SDHC/SDXC and Memory Stick formats.

In my testing, battery life on both was decent for casual use (~250 shots per charge), but for travel or pro work, carrying spares is advisable. TX9’s SD compatibility offers broader choice and lower media costs.
