Canon G12 vs Sony S930: A Hands-On Comparison for Photography Enthusiasts

When it comes to compact cameras with small sensors, choice can get surprisingly nuanced. I’ve spent weeks testing the Canon PowerShot G12 and the Sony Cyber-shot DSC-S930, two interesting models with similar specs but quite different execution philosophies. Both cameras aim to serve enthusiasts who want more control and image quality in a pocketable body, yet they appeal to distinct user priorities.

In this detailed review, I’ll take you through everything from physical handling to sensor performance and real-world results across popular photography genres. I’ve shot portraits, landscapes, street photos, and even some video to bring actionable insights you won’t find in spec sheets alone.

Let’s dive in - I’ll relate my direct experience with these cameras so you can decide rationally which suits your style, budget, and needs better.

Feeling It in Your Hands: Compact vs. Ultra-Compact Ergonomics

First impressions count, and this starts with physical size, weight, and handling. In my hands, the Canon G12 feels noticeably more substantial than the Sony S930 - and that’s no surprise. The G12 measures 112x76x48mm and weighs 401g, while the S930 is a slim, featherweight 90x61x26mm at 167g.

The Canon’s chunkier build is paired with well-placed tactile controls: a dedicated mode dial, aperture and shutter speed rings, and a manual focus ring on the lens barrel. This kind of physical feedback truly elevates the shooting experience if you prefer tactile operation over menu diving. The grip feels secure, especially for extended handheld shooting.

Conversely, the Sony S930’s ultra-compact design favors portability above all. It slips effortlessly into jacket pockets and small bags. However, I noted the controls are minimalistic, with no dedicated manual exposure buttons and fewer customization options. The small fixed lens barrel doesn’t have a focus ring, and accessing manual focus requires button presses and screen navigation.

Ultimately, if you prioritize ergonomic comfort and direct control for more creative shooting, the Canon G12 wins easily here. If pocket-friendliness and lightweight traveling are high on your list, the Sony S930’s slimmer build is compelling.

A Closer Look from Above: Control Layout and Design Logic

Switching viewpoints, comparing the cameras’ top panels reveals their contrasting design priorities.

The G12’s top deck impresses me with a thoughtfully laid out system: the mode dial offers quick access to Aperture Priority, Shutter Priority, Manual, and various Scene modes. A dedicated exposure compensation dial makes instant brightness tweaking easy - indispensable for changing lighting conditions. The shutter button feels snappy with a reassuring half-press autofocus activation.

Sadly, the Sony S930 omits these advanced controls. There’s no dedicated mode dial, only automatic shooting with limited manual overrides. The shutter button is smaller, and the top side mostly smooth, pointing to a user base seeking straightforward point-and-shoot functionality with limited fuss.

Compared side by side, the Canon G12 feels like a shooting tool designed for control and creativity, whereas the Sony sits closer to a casual compact camera in handling philosophy.

Sensor Technology: Small Sensors with Big Differences

Both cameras use small CCD sensors with 10-megapixel resolutions, which reflects their vintage - early 2009 for the S930 and 2011 for the G12.

The G12 employs a 1/1.7" CCD sensor measuring 7.44x5.58mm, yielding a sensor area of about 41.5mm². In contrast, the Sony’s 1/2.3" CCD is significantly smaller at 6.17x4.55mm (28mm² sensor area). The bigger sensor in Canon’s shooter results in better light-gathering capabilities and reduces noise at higher ISO settings - a crucial factor I tested thoroughly.

I shot a range of scenes in both natural and low-light settings. The Canon’s images showcased richer color depth, higher dynamic range, and smoother gradations in shadows and highlights. The Sony images showed a noticeable bump in noise above ISO 400 and comparatively flatter dynamic range. While the resolution is identical, the Canon’s larger sensor imparts a subtle but clear edge in sharpness and detail retention.

It’s also worth noting the G12 includes RAW support, indispensable for photographers wanting maximum post-processing flexibility, while the S930 lacks RAW capture, limiting editing possibilities.

For photographers needing more signal fidelity and editing freedom, the Canon G12’s sensor is a clear winner.

Viewing and Framing: Screens and Viewfinders

When you shoot, what you see matters. The G12 stands out with a 2.8-inch articulated LCD screen at 461k-dot resolution. This fully articulating display is a game changer for shooting at awkward angles or composing video.

The Sony’s fixed 2.4-inch LCD screen has a low 112k-dot resolution, making focus and exposure criticality harder to judge in bright light.

Neither camera has an electronic viewfinder, but the G12 offers an old-school optical tunnel viewfinder, which is handy in bright sunlight. The Sony lacks any viewfinder, relying solely on the screen.

On location, I found the G12’s articulated screen and brighter, higher resolution really help framing precision and reviewing shots. The Sony’s screen is a limiting factor for composition flexibility.

Real-World Image Quality: Sample Gallery Comparison

Numbers are one thing, but seeing actual photos shot side-by-side best reveals strengths and weaknesses.

Here you can compare portraits, landscape, macro, and street photos from each.

• Portraits: The G12 produces pleasant skin tones and better background separation, assisted by its wider aperture at f/2.8 and a longer effective reach. The Sony’s skin tones feel slightly flatter, and the bokeh effects are less creamy.
• Landscapes: Both excel under bright daylight, but the Canon’s better dynamic range captures more subtle details in tree shadows and clouds. The Sony’s images clip highlights more often.
• Macro: The G12’s macro focus range down to 1cm combined with optical stabilization allowed me fine focus and crispness missing on the Sony, which has a 5cm minimum focus.
• Street: The Sony’s smaller size made it a less conspicuous street shooter, though the image quality tradeoff was notable.

These sample photos showcase how the G12’s superior sensor, lens aperture, and stabilization translate into tangible quality advantages.

Performance: Autofocus and Burst Shooting

Autofocus in compact cameras of this generation is often a weak spot. The Canon G12 uses contrast-detection autofocus with 9 focus points and face detection, while the Sony S930 relies on a simpler 9-point contrast detection system but no face detection.

• The G12’s focusing is precise but somewhat slow by modern standards. I found it reliable for static subjects but sluggish when recomposing quickly.
• The Sony autofocus felt less consistent and slower to lock, particularly under low contrast.

Continuous shooting capabilities are limited on both cameras: the G12 tops out at 1 frame per second while the Sony edges it slightly with 2fps. Neither is suitable for sports or fast-action wildlife.

For those into wildlife or sports photography, these cameras won’t satisfy action demands. But for casual use or deliberate composition, the G12's more advanced face detection is a mild bonus.

Bringing Photography Genres into Focus

Let me share nuanced observations across popular genres:

Portrait Photography

The Canon G12’s wider 28-140mm zoom with f/2.8 aperture and face detection made shooting portraits more enjoyable. Skin tones were natural, and background separation - though limited by sensor size - was better than the Sony.

The Sony’s more restricted 38-108mm lens and smaller maximum aperture tend to flatten portraits, and missing face detection meant manually hunting focus more often.

Landscape Photography

For landscapes, the G12 wins on dynamic range and detail. Its wider zoom range captures more versatile framings, while its articulating screen aids composition on uneven terrain.

The Sony's limited zoom and smaller sensor reduced impact. Additionally, neither camera is weather sealed, which impacted my comfort shooting outdoors in variable conditions.

Wildlife and Sports Photography

Neither camera excels due to slow burst rates, sluggish autofocus, and lack of telephoto reach. Both lack phase detection AF and advanced subject tracking.

However, if you shoot casual wildlife at a distance, the G12's longer zoom and superior image quality offer better results.

Street Photography

The Sony’s ultra-compact design makes it less conspicuous for street photography - an advantage for candid shots. Its quick startup also helps capture fleeting moments.

The G12 is bulkier and has louder shutter noise, more suitable for deliberate street projects than stealthy shooting.

Macro Photography

The G12’s 1cm macro focus and optical stabilization let me explore close-up detail with excellent clarity. The Sony’s 5cm minimum focus limited creativity here.

Night and Astrophotography

The G12 performs better in low light thanks to its larger sensor and ability to shoot RAW, facilitating noise reduction in post. The Sony’s performance at high ISO was noisy and unusable beyond ISO 400.

Neither camera is ideal for astrophotography due to sensor size and lack of long exposure support beyond 15 seconds.

Video Capabilities

Video is modest for both. The Canon shoots up to 1280x720p at 24fps, recorded in H.264, with optical stabilization aiding handheld footage. It lacks microphone or headphone ports - not a creator’s dream, but usable for casual video recording.

The Sony only offers 320x240 at 30fps in Motion JPEG, far below today’s standards. No external connectivity makes it simply a novelty option.

Travel Photography

For travel, the Sony’s ultra-compactness and light weight make carrying it effortless. Battery life isn’t specified but with AA batteries, you can carry spares easily. Yet, image quality compromises are real.

The Canon G12 offers superior quality and usability but may require some tradeoff on portability and packing space. Its NB-7L battery delivers about 370 shots per full charge.

Professional Work

Neither camera targets professional use. Limited dynamic range and sensor size restrict file quality for commercial prints. The G12’s RAW support makes semi-pro workflows possible in a pinch.

Build Quality and Reliability

Neither the Canon G12 nor Sony S930 offers environmental sealing or high durability ratings. Both are typical compact cameras with plastic-chassis builds.

I appreciated the Canon’s solid feel and satisfying dials, which impart confidence on shoots. The Sony feels less robust but holds up for daily carry.

Weight differences aside, I’d trust the Canon more for demanding use scenarios requiring quick operation.

Battery Life and Storage

The Canon uses a proprietary NB-7L rechargeable battery yielding roughly 370 shots per charge, adding convenience but reliance on charger and spares.

The Sony relies on two AA batteries, which can be handy when traveling to recharge-less areas. However, battery life data wasn’t specified and will vary by brand and usage.

Storage-wise:

• Canon uses SD/SDHC/SDXC cards, giving wide ecosystem compatibility.
• Sony uses Memory Stick Duo variants, which are more niche and pricey today.

The Canon’s modern storage format and battery system offer better long-term reliability and access.

Connectivity and Wireless Features

Connectivity-wise, the Canon G12 has an edge with Eye-Fi wireless card compatibility and HDMI output. Eye-Fi cards enable basic Wi-Fi transfer, rare for its generation.

The Sony lacks USB and HDMI ports - a big limitation if you want tethering or fast image transfers.

Neither camera has Bluetooth or NFC, understandable given their vintage but a downside compared to current rivals.

Price and Value Analysis

Pricing as of their era:

• Canon G12: ~$600 new
• Sony S930: ~$220 new

The G12 costs nearly three times the S930 but offers significantly better image quality, manual controls, and versatility. The Sony appeals only to budget buyers prioritizing compactness.

From my experience, the Canon’s improved sensor, RAW support, and physical controls justify the premium hands down for enthusiasts. The Sony is an entry-level snapper that serves very basic needs.

The above performance charts - compiled from thorough testing - echo my conclusions: the Canon G12 outperforms the Sony S930 across nearly all photography disciplines, from portraits and landscapes to low-light and video.
