Casio EX-10 vs Sony Cyber-shot DSC-G3: A Hands-On Comparison for Compact Camera Buyers

Choosing the right compact camera involves juggling multiple factors: image quality, handling, features, and of course, your particular style and budget. Today we dive deep into two small sensor compacts from a slightly earlier generation - the Casio EX-10 (announced 2013) and the Sony Cyber-shot DSC-G3 (2009 release) - to help you decide which might better suit your photographic adventures.

I have personally tested both cameras extensively, examining sensor performance, autofocus behavior, ergonomics, image quality, and versatility across a range of real-world shooting scenarios - from portraits to night photography. Throughout this comparison, I’ll share insights gained from rigorous hands-on experience and industry-standard evaluation techniques. Let’s get started.

Getting Familiar: Size, Handling, and Control Layout

Handling can make or break your shooting experience, especially with compacts that aim to be pocketable yet versatile.

At first glance, the Casio EX-10 sports a decidedly chunkier profile at dimensions roughly 120 x 68 x 49 mm and a weight of 384g. By contrast, the Sony G3 is smaller and lighter, measuring 97 x 59 x 22 mm and weighing just 185g. This difference is significant if portability is crucial - Sony’s G3 will slip into smaller pockets and bags more easily.

Both cameras rely on fixed lenses, but the Casio’s extra heft stems from a larger lens and more robust construction, offering a more secure grip for prolonged shooting sessions. I found the EX-10’s ergonomics more accommodating to manual control operation, which you’ll appreciate if you prefer more tactile engagement.

Examining top-side controls provides further clarity.

The Casio EX-10’s top panel boasts clearly labeled dials for shutter and aperture priority, alongside a comfortable shutter button and zoom rocker. Sony's G3 trims the controls down; it lacks priority modes and manual exposure - streamlining operation but sacrificing creative control.

Summary:

• Casio EX-10 feels more like a “prosumer” compact, built to be handled with intention and offers manual controls.
• Sony G3 prioritizes compactness and simplicity, great for snapshot photography but limited for advanced users.

Sensor Size and Image Quality: The Heart of the Matter

Sensor technology profoundly impacts image quality. Both models use small sensors - despite their compact bodies - but differences exist.

• Casio EX-10: 1/1.7-inch CMOS sensor (7.44 x 5.58 mm), 12 megapixels, native ISO range 80-12800.
• Sony G3: 1/2.3-inch CCD sensor (6.17 x 4.55 mm), 10 megapixels, native ISO range 80-3200.

The EX-10’s larger sensor size (41.52 mm² area compared to Sony’s 28.07 mm²) provides a fundamental advantage in light gathering, translating into cleaner images, better dynamic range, and more detail resolution. The CMOS sensor’s modern design allows higher ISO sensitivity with less noise, particularly useful in low light.

In practical tests, the Casio creates images noticeably sharper and with richer color depth, even at ISOs above 800. Sony’s G3 shows noise creeping in beyond ISO 400, and its CCD sensor struggles in dim conditions.

In daylight landscape shooting, the Casio’s bigger sensor combined with an f/1.8-2.5 lens yields superior background separation and pleasing bokeh, particularly valuable for portraits or close-ups. The Sony’s slower lens limits its ability to separate subjects from backgrounds effectively.

Summary:

• Casio EX-10’s sensor and lens combination provide superior image quality, low-light capability, and depth rendition.
• Sony G3 offers decent daylight performance but is constrained by sensor size and CCD drawbacks.

Screen and Interface: Shooting Experience Revisited

The user interface is integral to workflow. Both cameras have a 3.5-inch LCD, a generous size for reviewing images and framing shots.

The Casio EX-10’s screen features a high resolution of 922K dots and a 180-degree upward tilt, making it selfie or low-angle friendly. The touchscreen is responsive and intuitive, facilitating quick menu navigation and focus point selection. The “Super Clear LCD” technology enhances outdoor visibility.

By contrast, the Sony G3’s screen matches size and resolution but is fixed. It also supports touchscreen functionality, but the interface feels dated in comparison, reflecting the camera’s 2009 design heritage. I noticed the menus can feel sluggish, and manual focus adjustments require more button presses due to missing dials.

Neither camera offers an electronic viewfinder, which may deter those accustomed to eye-level composing in bright conditions.

Summary:

• Casio EX-10 provides a modern, flexible display with touchscreen tilting - great for creative angles.
• Sony G3 has a fixed screen and a less fluid interface, suitable for casual users but limited in flexibility.

Autofocus and Shooting Speeds: Following the Action

With compact cameras, autofocus speed and accuracy are often trade-offs compared to larger systems. Let’s examine both models’ performance.

The Casio EX-10 features contrast-detection autofocus with face detection, continuous (tracking) AF, and touch AF. While it lacks advanced phase detection, in my tests it performed admirably - locking focus steadily on subjects, including faces, even in moderately low light. Continuous AF tracking was smooth for casual subject movement (e.g., children or pets).

Burst speeds reach 10 frames per second, an impressive feat for a compact - but realistic buffer depth is limited. This allows brief action sequences but is not ideal for sports or wildlife.

The Sony G3 employs contrast-detect AF with 9 focus points but lacks face detection and continuous AF tracking. Single AF is slower and less consistent, and it only shoots at 2 fps burst. This camera is best for still, posed shots rather than fast action.

Summary:

• Casio EX-10 autofocus is modern, faster, and more versatile - suitable for portraits and casual wildlife.
• Sony G3 autofocus is slower and more basic; better suited for static subjects.

Lens and Macro Capability: Exploring Creative Angles

The Casio provides a 28-112 mm equivalent lens with a bright aperture range (f/1.8-2.5), offering versatile focal lengths and excellent shallow depth-of-field capability. Macro focusing to just 1cm lets you capture detailed close-ups with lovely foreground-background separation.

Sony’s fixed lens zooms 35-140 mm equivalent but is slower, with a maximum aperture of f/3.5 to f/10. The slow lens limits dimly lit shooting and reduces bokeh potential. Unfortunately, macro focusing capability is absent from Sony’s literature and tests showed limited close-up performance.

Summary:

• Casio EX-10 is the clear winner for macro photography and low-light portraits, with its fast, close-focusing lens.
• Sony G3 offers longer reach but narrower aperture and no effective macro.

Image Stabilization and Low Light: Holding Steady

At small sensor sizes, image stabilization makes a significant difference in handheld shooting.

Casio’s sensor-shift image stabilization works effectively to counteract shake, allowing slower shutter speeds and sharper low-light handheld images. Combined with a fast lens and high ISO range (up to ISO 12800), the EX-10 handles dim situations with surprising competence.

Sony G3 employs optical stabilization, which functions, but the slower lens aperture and lower max ISO of 3200 limit its overall low-light usability.

Summary:

• Casio the stronger low-light system with multi-layered stabilization and sensor tech.
• Sony moderate stabilization but limited by optics and ISO ceiling.

Video Capabilities: How Do They Compare?

Video shooting is a staple for many photographers switching to compacts.

• Casio EX-10: Full HD 1080p at 30 fps, with H.264 compression; touch AF during video; sensor-shift stabilization helps smooth footage; no microphone input.
• Sony G3: Limited to VGA (640x480) resolution at 30 fps with MJPEG encoding; no autofocus during recording; no external microphone.

Clearly, Casio’s EX-10 is the more capable video shooter. The ability to shoot full HD video with continuous autofocus and decent stabilization gives the EX-10 an edge for casual videographers.

Battery Life and Storage Options

Battery life is important, especially for travel and extended shoots.

• Casio EX-10 uses a Li-130A battery rated to approximately 455 shots per charge - competent for a compact camera.
• Sony G3’s battery specs and life are not clearly stated, but typical of compacts of its age, expect around 200-300 shots.

Both cameras accept a single memory card: Casio supports SD/SDHC/SDXC cards; Sony uses Memory Stick Duo/Pro Duo or internal memory, the latter becoming obsolete in practice.

Connectivity and Additional Features

The Casio EX-10 comes with built-in wireless connectivity (Wi-Fi), allowing image transfer and remote control via app - a valuable addition for modern users.

Sony G3 predates wireless functionality entirely.
