Choosing a camera is never a simple matter, especially when the options stretch across a broad technological spectrum spanning different eras. Today, we pit two Sony Cyber-shot models that mark significant milestones in compact digital photography: the Sony Cyber-shot DSC-G3, launched in 2009, and the more advanced Sony Cyber-shot DSC-RX100 V, released in 2016. Though they share a brand lineage and compact DNA, these cameras cater to vastly different photographic needs and expectations.

Having personally tested thousands of cameras over the past 15 years, I’m excited to share a deep dive into how these two models stack up - sensor to sensor, button to button, and pixel to pixel. We’ll examine everything from build and handling to autofocus, image quality, and suitability across photography genres ranging from portraiture to wildlife and video.

Grab your lens cap and let’s get to it.

First Impressions: Size and Ergonomics Reflect Their Generations

At a glance, these two compacts couldn’t be more different physically, and that’s telling of both design trends and technological progress over their seven-year gap.

The Sony G3 is a distinctly pocketable small sensor compact, measuring 97 x 59 x 22 mm and weighing just 185g. Its body fits unobtrusively in a jacket pocket or small bag. This was a period when many still favored ultra-portable point-and-shoots, often sacrificing manual controls for simplicity.

Contrast this with the RX100 V, which is bulkier at 102 x 58 x 41 mm, tipping the scales at 299g. This is far from a ‘grab and go’ in your coat pocket - its more robust body offers better grip and a heftier presence befitting a premium advanced compact with a large sensor.

Notice the RX100 V’s pronounced grip and thicker profile versus the G3’s slimline physique.

Handling reflects these sizing differences. The RX100 V provides physical dials and a thoughtfully placed control ring on the lens for aperture or manual focus tweaking. Meanwhile, the G3 opts for a simpler interface with limited physical control wheels and a touchscreen interface (a rarity in 2009), although its touchscreen responsiveness feels sluggish compared to modern standards.

While the G3’s diminutive size appeals to minimalists and casual shooters, the RX100 V’s form factor suggests a camera designed for confident manual control and longer sessions. For photographers needing a comfortable grip and direct, tactile adjustments, the RX100 V stands out immediately.

Design & User Interface: Controls, Screen, and Viewfinder

Putting them side-by-side on a test bench illustrates the leap in user interface design. The G3 has a 3.5-inch fixed touchscreen with a resolution of 921k dots, a reasonable size and clarity for its day. Unfortunately, it lacks an electronic viewfinder (EVF), making it challenging in bright outdoor conditions where glare can diminish screen visibility.

The RX100 V counters this with a 3-inch tilting LCD (1229k dots) that tilts upward for low-angle and selfie positioning, plus a 0.59x magnification pop-up EVF, with an impressive 2,359k-dot resolution and full 100% coverage. This EVF makes a decisive difference in daylight framing accuracy and shooting stability.

The RX100 V’s dial and control layout cater to photographers who require instant access to key settings on the fly.

Navigating menus on the RX100 V is faster and more intuitive, thanks to dedicated function buttons and an intuitive command wheel. The G3 offers fewer hardware buttons and no manual exposure modes, limiting its usefulness for anyone wanting creative control beyond basic point-and-shoot setups.

G3 touchscreen feels dated against the RX100 V’s sharper, more flexible display and EVF combo.

In sum, the RX100 V’s design caters explicitly to enthusiasts and pros who demand an efficient interface for rapid changes, while the G3 suits novices valuing simplicity over depth.

Sensor Technology & Imaging: The Heart of the Matter

The sensor specs make for the starkest technical contrast here - and they tell us a great deal about the cameras' photographic capabilities:

The RX100 V’s 1-inch sensor gives it a significant advantage in light gathering and dynamic range compared to the G3’s 1/2.3" sensor.

The RX100 V’s larger 1-inch BSI-CMOS sensor is a standout feature among compacts, delivering superior dynamic range, better noise control at high ISO, and overall crisper image details. The Backside Illuminated (BSI) design also enhances low light sensitivity - key for night, astro, and indoor shooting.

Meanwhile, the G3’s CCD sensor was typical for high-end compacts of its era, but its smaller size limits its performance, resulting in more noise and less detail retention in challenging conditions. Absence of RAW support means you’re at the mercy of JPEG processing - limiting post-processing flexibility.

Real-world testing confirms these numeric advantages. On bright daylight landscapes, the RX100 V preserves highlight and shadow detail beautifully, whereas the G3’s images can clip highlights prematurely and exhibit more crushed blacks.

Autofocus Systems: From Basic Contrast Detection to Hybrid Power

The G3 employs a basic contrast-detection autofocus (AF) system with 9 AF points, lacking face detection, continuous or tracking AF modes. Focusing speed is moderate, adequate for static subjects but insufficient for subjects in motion.

The RX100 V is a different beast, boasting a sophisticated Hybrid AF system combining contrast and phase detection via 315 AF points covering a wide frame portion. This setup supports fast autofocus acquisition (~0.05 sec), face detection, continuous AF, tracking AF, and eye AF - features very valuable for diverse shooting scenarios.

During wildlife and sports testing with moving subjects, the RX100 V tracked targets consistently and maintained focus across bursts, while the G3 struggled to catch up, often hunting or missing focus altogether.

The RX100 V’s burst rate of 24 fps with continuous AF outstrips the G3’s 2 fps by a wide margin, making it far better suited for action photography.

Lenses & Optical Versatility: Zoom Range and Aperture

The fixed lens zoom ranges are quite telling:

• G3: 35-140mm equivalent (4x zoom), aperture F3.5-10.0
• RX100 V: 24-70mm equivalent (2.9x zoom), aperture F1.8-2.8

The G3’s longer reach makes it theoretically more attractive for telephoto work, albeit with a significantly slower maximum aperture that quickly stops down to f/10 at the telephoto end. This reduces versatility in low light and depth-of-field control.

By contrast, the RX100 V’s faster lens with a wide f/1.8 aperture at the wide end and bright f/2.8 at telephoto excels in creating pleasing bokeh - ideal for portraits and isolating subjects. The shorter zoom range is balanced by better overall sharpness, optical quality, and light-gathering ability.

The RX100 V also incorporates a macro focusing distance of 5cm, allowing close-up photography with good detail - a capability the G3 lacks.

Stability and Flash: Improving Usability

Both cameras feature optical image stabilization, which is a boon for handheld shooting, although implementations differ in effectiveness. The RX100 V’s system is more refined, enabling sharper shots at slower shutter speeds - critical for low light and telephoto use.

Regarding flash, the RX100 V boasts a more powerful pop-up flash with a range of 10.2m at Auto ISO, compared to the G3’s built-in flash effective up to 4.3m. The RX100 V’s flash supports Auto Exposure Bracketing and White Balance bracketing for creative lighting control, while G3 offers more basic flash modes.

Note, external flash support is absent in both, limiting expansion for advanced lighting setups.

Video Capabilities: From VGA to 4K

If video is on your radar, the RX100 V dramatically outperforms the G3:

• G3: Limited to 640x480 (VGA) at 30fps, Motion JPEG format - quite basic and clearly dated.
• RX100 V: Can record 4K UHD (3840x2160) at 30p with high bitrates (up to 100 Mbps) and modern codecs (XAVC S), plus Full HD slow motion at up to 960fps in drop frame mode for creative ultra slow-mo.

The RX100 V also supports headphone and microphone monitoring limitations (no ports) - standard for compact cameras, but still a consideration for video enthusiasts wanting audio control.

In practical use, the RX100 V’s advanced encoding and stabilization produce handheld footage with less artifacting and jitter, ideal for run-and-gun shooting or travel vlogging.

Battery Life and Connectivity: Staying Powered and Connected

Sony’s NP-BX1 battery in the RX100 V provides approximately 220 shots per charge, consistent with camera size and power draw of the larger sensor and processor. The G3’s battery life details are unspecified but expectedly shorter due to older technology and the efficiency gap in processors.

Connectivity-wise, the RX100 V shines with built-in Wi-Fi and NFC, enabling easy smartphone pairing for image transfer and remote control - an essential feature for fast social sharing or tethered shooting. The G3 lacks wireless connectivity entirely, relying on USB 2.0 and Memory Stick storage.

Memory storage options broaden from the G3’s Memory Stick Duo/Pro Duo format (now legacy) to the RX100 V’s acceptance of SD/SDHC/SDXC cards, permitting greater capacity and faster write speeds.

Build Quality and Environmental Resistance

Neither camera offers weather sealing or ruggedized housing. However, the RX100 V feels noticeably more robust and solidly constructed. Its magnesium alloy chassis reassures with a premium finish, while the G3’s plastic body, though reasonably sturdy for casual use, doesn’t inspire confidence in tough conditions.
