Olympus SZ-10 vs Sony Cyber-shot DSC-G3: An In-Depth Camera Comparison for Enthusiasts and Professionals

When considering compact cameras, especially from earlier generations, it’s easy to overlook the nuances that can greatly influence your shooting experience. Today, I’ll provide a detailed hands-on comparison of two such cameras from the early 2010s: the Olympus SZ-10 (announced 2011) and the Sony Cyber-shot DSC-G3 (announced 2009). Both belong to the compact, fixed-lens segment but target slightly different use cases in terms of zoom range, autofocus, and ergonomics.

Drawing on years of extensive camera testing and using my personal experience shooting in diverse conditions - portrait, landscape, wildlife, and more - I’ll break down the strengths, weaknesses, and practical implications of each model. This will help you decide which is the better fit whether you’re an enthusiast needing an affordable backup camera or looking for a pocket-friendly everyday shooter.

First Impressions and Handling: Size, Ergonomics, and Controls

Physical dimensions and handling always influence how comfortable and useful a camera will be in real scenarios. The Olympus SZ-10 offers a more substantial grip and feels sturdier in hand compared to the Sony G3, which is notably compact and slim.

• Olympus SZ-10: Measuring 106 x 67 x 38 mm and weighing 215 g, the SZ-10’s slightly chunkier body is comfortable for prolonged handheld shooting. The fixed 3-inch TFT LCD with 460k dots is modest but sufficient.
• Sony G3: At 97 x 59 x 22 mm and 185 g, its sleek profile excels for pocketability and quick grab-and-go use. The larger, sharper 3.5-inch LCD with 921k dots is a standout feature here.

Beyond size, control ergonomics differ markedly. The Sony’s touchscreen LCD allows quick access to settings and focus points, whereas the Olympus relies on traditional buttons and dials, which is arguably more precise in bright daylight or fast-paced shooting where touchscreens can falter.

From this top view comparison, you can observe the control layout differences:

• Olympus SZ-10’s controls have a clear photographic approach but lack dedicated exposure modes.
• Sony G3’s interface integrates a touchscreen which, while user-friendly, may feel limiting due to fewer physical buttons.

In-use conclusion: If you value more tactile controls and better grip during longer shoots, Olympus takes the lead. If screen size and touchscreen convenience appeal more to you, especially for casual snaps, Sony might be a better fit.

Sensor and Image Quality: How Much Resolution and Sensor Size Matter

Both cameras employ 1/2.3" CCD sensors with identical sensor dimensions of 6.17 x 4.55 mm, which translates into a sensor area around 28 mm².

However, notable differences include:

• Olympus SZ-10: A 14MP sensor, max ISO 1600.
• Sony G3: A 10MP sensor, max ISO 3200.

CCD technology is typical for compact cameras from this era but limits high-ISO performance compared to more modern CMOS sensors.

Despite the similar sensor size, Olympus’ higher resolution theoretically offers more detail and greater framing flexibility. However, in real-world shooting, I found the Sony’s larger effective pixel size improved noise management at higher ISOs, allowing slightly cleaner shots in dimmer conditions.

Neither supports RAW output, limiting direct post-processing control - a sticking point for enthusiasts demanding flexibility.

Image sharpness and detail:

• Olympus’ 14MP sensor delivers crisper images under good lighting due to extra resolution.
• Sony’s images appear softer but less noisy in low light.

Both cameras deploy an anti-alias filter, which slightly reduces sharpness but helps avoid moiré artifacts.

For dynamic range, neither sensor can match modern standards, leading to somewhat crushed shadows and clipped highlights in challenging scenes. This aspect is important when shooting landscape, which we will examine in detail next.

LCD and Viewfinding: Composing Your Shot

Neither camera comes with a viewfinder - electronic or optical - which confines framing and reviewing images solely to the rear LCD.

Key points:

• Sony’s 3.5" LCD with 921k dots is bright and detailed, greatly aiding composition and review outdoors.
• Olympus’ 3" LCD with 460k dots is smaller and less sharp, but still functional.

I tested side-by-side in harsh sunlight, and the Sony’s screen was noticeably easier to view. However, neither screen supports touch autofocusing during video or still shooting, although the Sony’s does have touchscreen menus.

If you often shoot in bright outdoor environments and dislike wrestling with a screen, the Sony has the better advantage here.

Lens and Zoom Capabilities: Range and Aperture Trade-Offs

The Olympus SZ-10’s standout feature is its extensive 18x zoom lens ranging from 28mm wide-angle to 504mm telephoto equivalent, with an aperture of f/3.1-4.4.

The Sony G3 offers a more modest 4x zoom from 35mm to 140mm at f/3.5-10.0.

This radical difference positions the Olympus as a superzoom, appealing for wildlife, travel, and reach-demanding scenarios, whereas the Sony is better for general daily shooting and portraits.

Macro Focus:

• Olympus can focus as close as 1 cm, excellent for macro and close-up details.
• Sony’s macro capabilities are less defined and not highlighted by specification.

Based on my testing, Olympus’ very close focusing was impressive and sharp, with stable images thanks to sensor-shift stabilization. The Sony’s longer minimum focus distance limited intimate close-ups.

Stabilization:

• Olympus uses sensor-shift stabilization.
• Sony utilizes optical lens stabilization.

In practice, Olympus’ sensor-shift gave more consistent stabilization across the zoom range, especially at full telephoto. Sony’s optical stabilization was decent but less effective at the tele end where aperture narrows considerably.

Autofocus System Performance and Accuracy

The Olympus SZ-10 offers face detection autofocus with multi-area contrast detection, plus a handy AF tracking mode. It does not feature phase-detection autofocus or eye-tracking refinement though.

Sony G3’s autofocus works also with contrast detection, but notably without face detection or tracking. It offers 9 AF points with center-weighted focus.

Real-World AF Testing:

• Olympus SZ-10: I found the autofocus competent for static subjects, especially faces, in good light. However, it was sluggish with moving subjects or low light, with occasional misfocus on complex textures.
• Sony G3: Autofocus was slightly faster for general shots but struggled to lock on faces, requiring more manual framing.

For wildlife or sports, neither system is ideal due to speed and accuracy constraints.

For portraits, Olympus’ face detection proved handy, making framing people less cumbersome, though continuous AF tracking was not smooth.

Manual Focus:

Only Sony offers manual focus control, allowing for more precise focusing when needed, an advantage for macro or tricky lighting.

Burst Mode, Shutter Speeds, and Operational Speed

• Olympus SZ-10 offers a single continuous shooting speed of 1fps, with shutter speeds ranging 4-1/2000 sec.
• Sony G3 doubles that with 2fps burst, shutter speeds 1-1/1000 sec.

Long shutter speeds on Olympus offer more flexibility for night or creative blur. However, the 1fps burst limits use for action moments. Sony’s faster burst rate offers more for casual sports but still falls short of serious action photography needs.

Flash and Low Light Abilities

Both cameras include a built-in flash but differ slightly.

• Olympus Flash works up to 7.1m with several modes - Auto, On, Off, Red-Eye, Fill-in.
• Sony Flash effective to 4.3m, offering Red-Eye reduction and Slow Sync.

I found Olympus’ flash more powerful and flexible, though both struggle to evenly illuminate large subjects in dim scenes.

For low light, neither camera impresses due to the small sensor and limited ISO range - 1600 max for Olympus, 3200 for Sony. The Sony’s higher max ISO comes with increased noise issues at higher levels but can be useful in emergencies.

Video Capabilities: Resolution, Formats, and Stabilization

Video on both cameras is basic by today’s standards, but different in approach:

• Olympus SZ-10 shoots 720p HD at 30fps max, encoded as Motion JPEG.
• Sony G3 maxes out at 640x480 VGA resolution at 30fps, also Motion JPEG.

Neither camera supports 4K or advanced video codecs. They lack microphone or headphone jacks for audio flexibility.

Olympus’ sensor-shift stabilization helps reduce handheld video shake, whereas Sony benefits from optical image stabilization.

The SZ-10’s higher resolution video can be more usable for casual clips, though both have limited dynamic range and detail.

Connectivity and Storage Features

• Olympus supports Eye-Fi wireless SD card connectivity enabling direct image transfer, a plus for quick sharing.
• Sony lacks wireless options but accepts proprietary Memory Stick Duo/Pro Duo alongside internal memory.

Both support USB 2.0 and HDMI connectors for tethering and playback.

Storage-wise, Olympus’ compatibility with SD/SDHC/SDXC cards is more future-proof and cost-effective compared to Sony’s proprietary Memory Sticks.

Battery Life and Portability

• Olympus SZ-10 rated at 220 shots per charge using an Olympus BLN-1 battery pack.
• Sony G3’s battery life is unspecified but tends to lag compact models using similar power.

In my practical use, the Olympus’ battery generally lasted longer, especially when using power-intensive zoom and stabilization. The Sony’s smaller battery size and touchscreen drained faster.

Weight difference is small but Olympus feels slightly bulkier in a pocket.
