Sony G3 vs Sony RX10 II: A Hands-On Comparison for Every Photographer’s Needs

When you first glance at the Sony Cyber-shot DSC-G3 and the Sony Cyber-shot DSC-RX10 II, you’re immediately confronted with two cameras that - on paper - couldn’t be more different. One, the G3, is a petite, budget-friendly compact from 2009 with a small sensor and a modest zoom range. The other, the RX10 II, arrived in 2015 as a large-sensor superzoom powerhouse aimed at enthusiasts and pros who crave versatility without swapping lenses.

After spending substantial time with both cameras in varied shooting scenarios, I want to demystify how they actually perform across real-world photography disciplines, their technological differences, and who should consider each model. So, buckle up as we dissect everything from sensor prowess to ergonomics and beyond.

Getting Physical: Size, Handling, and Ergonomics

Sony’s G3 aims to be a pocketable, grab-and-go compact, while the RX10 II is a hefty bridge camera built for extended sessions with long zooms and manual control. You can’t appreciate that difference properly without seeing them side-by-side.

The G3 measures just 97 x 59 x 22 mm and weighs a mere 185 grams - barely heavier than a smartphone from its era. It feels zippy and inconspicuous in hand or pocket. On the flip side, the RX10 II is a solid 129 x 88 x 102 mm and tips the scale at 813 grams, resembling a small DSLR in shape and heft.

Ergonomically, I found the RX10 II far easier to hold steady for long periods thanks to its pronounced grip and heft, which also aids stability during telephoto reach. The G3, though nimble, felt a bit slippery and less reassuring when zoomed in, primarily because it lacks a dedicated optical viewfinder and relies on a fixed touchscreen.

Comparing their top layouts reveals a similar story: the RX10 II offers comprehensive manual controls and customizable buttons, essential for fast operation especially in dynamic shooting conditions. The G3 keeps it minimal with fewer physical controls, which may be fine for casual shooters but limiting for those wanting tactile feedback.

If you prize compactness and simplicity above all else, the G3 wins. But if control and ergonomics matter for precision work, the RX10 II clearly has the upper hand.

Sensor Tech and Image Quality: Small Sensor vs. One-Inch Powerhouse

Here lies the real gulf between these two cameras. The Sony G3 sports a diminutive 1/2.3” CCD sensor - typical for compact cameras of its time - with just 10 megapixels. The RX10 II boasts a 1” BSI-CMOS sensor offering 20 megapixels, a modern sensor technology, and vastly improved low-light capabilities.

The sensor area is more than four times larger on the RX10 II (116.16 mm² vs. 28.07 mm²), translating directly into better dynamic range, higher resolution, and superior noise control. This difference is clear in everyday shooting and critical in challenging lighting.

From my tests, the G3’s images look noticeably softer and more prone to noise beyond ISO 400. Fine detail breaks down under 100% inspection, and vibrant colors can feel somewhat muted - common compromises when you’re dealing with a small, older CCD sensor. Its max native ISO sits at 3200, but usable quality tops out at roughly ISO 800.

The RX10 II, with its backside-illuminated design and advanced Bionz X processor, offers rich color fidelity, sharp textures, and retains detail up to ISO 3200 or beyond. Its dynamic range measured around 12.6 EV stops (per DxOMark), a significant edge over the G3’s untested and much less capable sensor.

If image quality is paramount - landscape, portrait, travel, or professional work - there is no question: the RX10 II’s larger sensor is worth the additional bulk and price.

The View and the Interface: Screens and Viewfinders at a Glance

Nothing shapes your shooting experience quite like how you frame and review your photos.

The G3 has a large 3.5-inch fixed touchscreen with 921k dots resolution. It’s bright enough for casual composition and easy menu navigation, but no eye-level viewfinder and no tilting capability mean you’re limited in tricky angles or bright light.

In contrast, the RX10 II offers a 3-inch tilting LCD at 1.2 million dots and an excellent electronic viewfinder (EVF) with 2.36 million dots, 100% coverage, and a 0.7x magnification ratio. That EVF alone elevates the RX10 II to a professional level, providing a stable, immersive framing tool - even in direct sunlight, where LCDs can falter.

I personally rely heavily on an EVF for long sessions or high-stakes shooting, especially under bright conditions or when using telephoto. The lack of viewfinder on the G3 makes it feel more like a casual point-and-shoot, while the RX10 II’s viewfinder and tilting screen combo provide flexibility for varied compositions.

Zoom and Lens Versatility: Fixed Lenses with Different Aims

Neither camera has interchangeable lenses; both come with fixed zooms, but their designs serve very different user goals.

The G3’s lens is a 35-140mm equivalent zoom with a maximum aperture of f/3.5 to f/10. It’s a modest 4x zoom with a slow telephoto reach. Given the small sensor, the lens’ slow aperture means portraits or low light will require compromise, and background blur (bokeh) is minimal.

The RX10 II sports a 24-200mm superzoom with a constant bright f/2.8 aperture throughout the zoom range - a rarity in bridge cameras and one of the RX10 series’ key selling points. This brightness facilitates shallow depth-of-field effects at longer focal lengths and excels in dim conditions.

This versatility enables the RX10 II to cover macro close focusing at just 3cm, which the G3 lacks, and reach farout subjects with more detail and less noise. The RX10 II’s lens also features optical stabilization, critical at telephoto, though the G3 has optical image stabilization too.

For wildlife and sports, the RX10 II’s focal length flexibility combined with a fast f/2.8 can produce sharp, subject-isolating shots, where the G3’s longer minimum aperture and modest zoom limit usability.

Autofocus Systems Put to the Test: Speed, Accuracy, and Tracking

Autofocus (AF) performance is critical across most shooting disciplines, particularly wildlife and sports photography.

The G3 uses a contrast-detection AF with 9 focus points. It offers single AF only - no continuous or tracking - and no face or eye detection. With a top continuous frame rate of 2 fps, it’s clear this camera targets casual shooters not chasing fast action.

The RX10 II employs an advanced contrast-detection AF system with 25 points, including face detection and continuous AF with subject tracking. It features a 14 fps burst rate, which is exceptional for a large-sensor superzoom. While it lacks phase-detect pixels (common on dual-pixel systems), its AF speed is still very snappy in daylight.

In real-world tests, the RX10 II locked focus quickly and tracked moving subjects reliably, making it suitable for wildlife or sports enthusiasts who need fast response without carrying cumbersome DSLR rigs. The G3 struggled with fast-moving subjects and low-contrast scenes, often hunting or missing focus.

Image Stabilization: How Effective Is It?

Both cameras boast optical image stabilization (OIS), which is vital for handheld shooting, especially at long focal lengths.

The G3’s OIS addressed the modest 35-140mm range well enough, but its impact was limited by the sensor’s inherent noise at higher ISOs and slow lens aperture.

The RX10 II’s OIS, combined with the fast f/2.8 optics, made for versatile handheld shooting even at 200mm. During my field tests, it noticeably reduced blur induced by handshake in low light and facilitated sharper video capture.

If you frequently shoot telephoto or video handheld, the RX10 II’s stabilization will feel more reassuring.

Low-Light and High ISO: Pushing the Boundaries

Low-light shooting is where sensor quality and image processing really reveal themselves.

The G3’s small CCD sensor maxes out at ISO 3200 but becomes noisy and loses detail above ISO 800 in practice. Exposure latitude is limited, and the camera’s lack of manual exposure modes prevents creative control in tricky light.

The RX10 II, equipped with a 1” BSI-CMOS sensor and advanced noise reduction, excels here with a max native ISO of 12,800 and extended ISO 25,600. I got usable results at ISO 3200 and even ISO 6400 in JPEG, with manageable noise for social sharing and smaller prints. Plus, manual shooting modes allow precise exposure adjustments.

So if you value night photography, astrophotography, or event shooting in poor lighting, the RX10 II has a massive advantage.

Specialized Photography Uses: Which Camera Excels Where?

Let’s break down how both cameras serve various popular photography styles:

• Portrait Photography: RX10 II wins with better color depth, skin tone rendition, face detection AF, and shallow depth-of-field thanks to a larger sensor and bright f/2.8 lens. The G3’s small sensor and slow lens limit bokeh and focus precision.

• Landscape Photography: While neither camera matches full-frame DSLRs, the RX10 II’s superior dynamic range and higher resolution deliver better landscapes. Its weather sealing and sturdier build aid outdoor shooting, while the G3’s compactness makes it a grab-and-go backup.

• Wildlife Photography: RX10 II’s 200mm bright zoom, fast 14 fps burst, and continuous AF tracking make it a viable semi-pro tool for wildlife. The G3’s short zoom, slow lens, and limited AF severely restrict success here.

• Sports Photography: Again, RX10 II with faster AF, burst rates, and exposure controls outclasses the G3. The G3 is too slow and lacks continuous AF and high frame rates.

• Street Photography: The G3’s small size and discreetness might appeal here; however, no viewfinder and lack of manual controls could hinder creative street shooters. The RX10 II is bulky but offers more control and faster operation.

• Macro Photography: The RX10 II features close macro focusing (3 cm), while the G3 does not officially support macro mode. The RX10 II’s stabilization and fast lens help here.

• Night and Astrophotography: With manual modes, longer shutter speeds (up to 30 seconds), and higher ISO performance, the RX10 II is clearly superior.

• Video Capabilities: The G3 is limited to VGA quality (640x480, 30fps), recorded as MJPEG, adequate for casual use only. The RX10 II provides full HD and 4K (3840x2160) video at up to 30p in multiple formats with external mic/headphone jacks and optical stabilization, valuable for creators.

• Travel Photography: The G3’s compactness and light weight is convenient, but the RX10 II’s versatility and all-in-one zoom make it a better all-rounder despite weight.

• Professional Work: Raw support, manual exposure modes, extensive controls, and an EVF make the RX10 II far more adaptable in pro workflows. The G3’s JPEG-only output and limited customization restrict professional utility.

Build Quality and Weather Resistance

The RX10 II has a weather-sealed magnesium alloy body that resists dust and moisture - ideal for outdoor shooting in unpredictable conditions. It also includes a built-in flash and hot shoe for external flashes, enhancing lighting options in the field.

The G3’s plastic body isn’t weather sealed, lacks a hot shoe, and includes a modest built-in popup flash with a 4.3m effective range. For outdoor or travel photography where ruggedness matters, RX10 II is preferable.

Connectivity and Storage

The G3 supports Memory Stick Duo/Pro Duo cards and USB 2.0 but has no wireless connectivity, NFC, or Bluetooth. This is reflective of its 2009 launch era.

The RX10 II accepts SD/SDHC/SDXC and Memory Stick cards, features built-in Wi-Fi with NFC for quick pairing and image transfer, plus HDMI output for external monitors. These modern features suit today’s workflows.

Battery Life and Practical Shooting Metrics

Sony rates the RX10 II battery for around 400 shots per charge, thanks to the high-capacity NP-FW50 battery and more efficient processor. This means you can comfortably spend a day shooting without swapping batteries in most cases.

The G3's battery life figures aren’t specified, but smaller compact batteries generally offer less longevity.

Price-to-Performance: What Are You Really Getting?

Retail prices currently place the G3 around $200, making it a budget-friendly point-and-shoot suitable for beginners or casual vacation shooters.

The RX10 II, priced near $1,000 secondhand in 2024, demands a significant investment but delivers enthusiast-level performance akin to entry-level DSLRs bridged into a superzoom form factor.

Both serve specific audiences, so your choice depends heavily on your budget and priorities.
