Canon G12 vs Sony W730: A Hands-On Comparison for the Savvy Photographer

Over the last 15 years, I’ve handled and rigorously tested hundreds of compact digital cameras, spanning from ultra-pocketable point-and-shoots to enthusiast-level compacts with manual overrides. Today, I want to walk you through a deep dive comparison between two interesting small sensor compacts: the Canon PowerShot G12, announced in early 2011, and the Sony Cyber-shot DSC-W730 from 2013. Both appeal to hobbyists and casual photographers, yet they occupy distinct niches in design philosophy, feature sets, and real-world usage.

Having spent weeks with each camera, shooting a range of subjects - portraiture, landscapes, street scenes, and video - I’m confident this article will equip you to decide which better fits your photographic style and budget. I’ll share my practical insights alongside technical measurements, ensuring that you get an informed assessment grounded in hands-on experience.

How They Feel: Size, Ergonomics, and Handling

Let’s start by addressing something that immediately impacts daily use: physical handling. There’s no substitute for how a camera feels in your hand after hours of shooting.

The Canon G12 is a relatively hefty compact at 401 grams, measuring 112 x 76 x 48 mm. Its design unmistakably leans toward the enthusiast photographer, boasting a textured grip, a fully articulated 2.8-inch screen, and a traditional control layout that encourages manual adjustments. In contrast, the Sony W730 is pocket-friendly and minimalist - at just 122 grams and a slim 93 x 52 x 22 mm, it slips easily into any bag or even a coat pocket, but it sacrifices some control for convenience.

The G12’s weight and robust build give a reassuringly solid feel, steadying the camera during slower shutter speeds or macro work. Ergonomically, Canon nails it with dedicated dials for aperture, shutter speed, and exposure compensation - a boon when shooting in manual modes or in fast-changing lighting.

Sony’s W730 opts for a sleek, slim form but limits grip comfort, especially during prolonged use. The button layout is sparse and less tactile, relying more on menu navigation. However, its lightweight nature and smaller footprint make it excellent for casual walks and travel when you want an unencumbered experience.

If you prefer a serious compact with manual controls and a substantial feel, the G12 wins. If pocketability and quick point-and-shoot simplicity matter most, the Sony is compelling.

Design and Controls: Balancing Manual Freedom and Simplicity

Moving to more granular details, the control scheme profoundly influences creative efficiency.

The Canon G12 sports a classic enthusiast compact look with a top LCD display (although no dedicated status screen on top), various customizable buttons, a mode dial, and a neat joystick/d-pad system. The articulated screen adds compositional flexibility - very handy for low-angle macro shots or awkward portrait angles.

In contrast, the Sony W730’s fixed 2.7-inch touchscreen (surprisingly for its category and time) introduces a more modern interface. However, it lacks physical dials or a mode dial, limiting instant access to manual exposure modes since the camera itself doesn’t support them. This simplifies operation but at a cost to advanced users.

In my shooting sessions, the G12’s manual dials and customizable buttons made aperture and shutter speed adjustments intuitive to dial in on location without fumbling through menus. The touchscreen on the Sony is responsive and user-friendly but geared toward point-and-shoot scenarios.

If your shooting style embraces manual control and speed, the G12’s layout is superior. If you prefer effortless, touchscreen-driven simplicity, the W730 fits the bill.

Sensor and Image Quality: CCD vs CCD, Size Matters

Both cameras feature CCD sensors - a notable aspect given the era, as CMOS sensors dominate modern compacts. The G12 houses a 1/1.7" sensor measuring 7.44 x 5.58 mm with a 10-megapixel resolution, while Sony’s W730 has a smaller 1/2.3" sensor at 6.17 x 4.55 mm but pushes 16 megapixels.

The larger sensor area of the Canon G12 (approximately 41.5 mm²) compared to the Sony’s 28.1 mm² results in generally better image quality concerning noise performance, dynamic range, and color depth.

In my own ISO noise tests, the G12 maintained cleaner images up to ISO 800, outperforming the W730, which showed more pronounced noise and detail loss beyond ISO 400. The G12 also exhibits superior dynamic range (~11.2 EV vs. unknown but less on Sony), giving more headroom for recovering highlights and shadows in post-processing - a vital advantage for landscape and travel photography.

While the Sony W730’s higher megapixel count allows for larger prints or aggressive cropping, its smaller sensor struggles in low light, rendering noisier images with less color fidelity. The Canon’s 10 MP strikes a practical balance between resolution and quality.

Both cameras apply anti-alias filters to reduce moiré artifacts, and both support JPG, but only the G12 offers RAW file support, crucial for those wanting maximum editing flexibility.

The Rear Screen and Viewfinder: Composing Your Shot

Here, the Canon G12 again emphasizes versatility. Its articulated 2.8-inch screen offers 461 k-dot resolution, brighter and sharper than the Sony’s fixed 2.7-inch touchscreen at 230 k-dots.

The G12’s articulation is key when composing in tricky angles - overhead shots, macro work, or video vlogging are more comfortable when you can angle the screen accordingly.

Moreover, the Canon includes an optical tunnel viewfinder, although basic and without electronic overlays, which allows composing in bright sunlight without screen glare - a feature absent on the Sony W730.

Sony’s touchscreen does support live view framing and offers intuitive touch-to-focus, but the lack of an articulated display or viewfinder slightly limits framing flexibility outdoors. For casual snapshots, this is rarely a dealbreaker, but for serious photographers or videographers, the G12’s display system shines.

Autofocus and Operation Speed: Precision vs. Simplicity

Both cameras utilize contrast-detection autofocus, but there are significant differences in speed and focus area options.

The Canon G12 has nine focus points with face detection and multi-area AF modes, while the Sony W730 offers several AF modes including face and center-weighted focus but with unclear focus point count.

In real-world shooting, I observed:

• Canon G12 AF is moderately fast but a bit sluggish in low light due to the CCD sensor and older Digic 4 processor. It lacks continuous AF for moving subjects but excels in stills with precise single-point focus.

• Sony W730 AF is quicker in daylight but less accurate in low light and struggles with tracking moving subjects. Touch-to-focus helps compose quickly though accuracy consistency fluctuates.

Continuous AF and rapid burst shooting are limited on both, with 1 fps continuous shooting - clearly not for sports or wildlife action bursts.

Both cameras lack phase detection AF, and neither supports animal eye AF, which modern cameras leverage well for pet photography.

Image Stabilization and Lens Specs: Zoom Reach and Sharpness

The Canon G12 has a 5x optical zoom equivalent to 28-140 mm in 35mm terms, with a bright aperture range of f/2.8–4.5, lending itself well to general photography including low-light portraits and macro. In contrast, the Sony W730 boasts a more extensive 9x zoom from 25-224 mm, but with a smaller maximum aperture range of f/3.3–6.3, limiting light gathering at the telephoto end.

Both cameras feature optical image stabilization, a non-negotiable for handheld shooting, especially at longer focal lengths. I found Canon’s system effective, with up to three stops of shake reduction, beneficial for the lower zoom range. The Sony’s longer zoom sometimes exaggerated handshake but still helps.

The G12’s macro focus distance of 1 cm is impressively close, allowing for detailed close-ups. Sony’s macro mode starts at 5 cm, less intimate but still serviceable.

While the G12’s lens offers superior sharpness and contrast, especially at wider apertures, the W730’s extended zoom appeals more to casual users wanting reach flexibility for travel or wildlife snapshots.

Low Light, Noise, and ISO Performance

With a max ISO of 3200 on both, I conducted side-by-side low-light tests in urban nightlife and indoor settings. Here the Canon G12’s larger sensor and better noise control proved a clear winner, rendering images with finer grain and retaining more detail up to ISO 800–1600. Beyond that, noise became more apparent but still manageable.

The Sony W730 starts at ISO 100 and goes to 3200 but yields noticeable noise already from ISO 400 upwards. Images lose sharpness rapidly under artificial lighting, limiting practical low-light shooting. The G12 is more forgiving, suitable for event, indoor, and street photographers who want cleaner results in dim conditions.

Video Capabilities: HD but Basic

Both cameras shoot 720p HD video but with important differences.

The Canon G12 records 1280 x 720 at 24 fps using H.264 compression, with manual exposure control during video - fantastic for videographers wanting creative control. Unfortunately, it has neither microphone nor headphone jacks, limiting audio quality and monitoring.

The Sony W730 also offers 720p at 30 fps but uses MPEG-4 and AVCHD formats without manual exposure options, suitable for straightforward casual clips but less versatile creatively.

Neither camera offers 4K or advanced video tools common today, but for basic family video or simple b-roll, they deliver serviceable results.

Battery Life and Storage: How Long Can You Shoot?

The Canon G12’s NB-7L battery delivers approximately 370 shots per charge per CIPA standards, slightly better than the Sony W730’s NP-BN battery rated around 240 shots. Real-world use shows the Canon’s battery life allows extended shooting sessions, especially when using the optical viewfinder to save LCD usage.

In terms of storage:

• The Canon supports SD/SDHC/SDXC cards.
• The Sony adds Memory Stick compatibility alongside SD cards.

Single card slots in both require careful management during shoots, but versatility in media types works in Sony’s favor.

Connectivity and Extras: Wireless and Ports

Connectivity differences illustrate the generation gap:

• The Canon G12 offers Eye-Fi card support enabling wireless photo transfer through compatible SD cards and includes an HDMI port for display on TVs.
• The Sony W730 lacks wireless features and HDMI but offers a touchscreen interface for easier playback navigation.

Neither includes GPS, Bluetooth, or NFC, expected for cameras targeting this class and era.

Durability and Weather Sealing: Field Reliability

Neither model is weather-sealed, dustproof, or shockproof. Both require careful handling outdoors under extreme conditions. The Canon’s more rugged build quality and larger grip lend confidence for outdoor excursions, whereas the plastic-bodied Sony is more suited for casual indoor or protected shooting environments.

Image Samples: Seeing Is Believing

I captured a series of images illustrating daylight landscapes, portraits, macro flora, and street scenes with both cameras. They exemplify the G12’s richer color reproduction, better dynamic range, and more natural skin tones, while the W730’s increased zoom shows off reach but with softer results and increased noise after ISO 400.
