Olympus PEN E-PL8 vs Sony Cyber-shot DSC-G3: A Deep-Dive Comparison for Camera Buyers in 2024

Choosing the right camera can feel overwhelming with so many options available. Today, I’m comparing two very different yet intriguing models: the 2016 Olympus PEN E-PL8 mirrorless and the 2009 Sony Cyber-shot DSC-G3 compact. These cameras represent distinct segments - one an entry-level mirrorless designed for enthusiasts wanting flexibility and image quality, the other a compact aimed at casual users valuing simplicity and portability.

Having personally tested thousands of cameras across genres, I will share detailed insight into their technical foundations, real-world performance, and their suitability for different photographic disciplines. Whether you prioritize image quality, speed, portability, or price, this thorough comparison will help you decide if either camera fits your needs in 2024.

First Impressions: Form Factor and Ergonomics

The Olympus E-PL8 sports a rangefinder-style mirrorless body supporting interchangeable lenses (Micro Four Thirds mount), while the Sony G3 is a traditional compact with a fixed lens.

Physically, the Olympus E-PL8 measures approximately 115 × 67 × 38 mm and weighs 357g, offering a handier grip with more pronounced controls. In contrast, the Sony G3 is ultra-compact at 97 × 59 × 22 mm and 185g - almost pocketable.

Examining top controls - the E-PL8 features dedicated dials and buttons for shutter speed, aperture, and exposure compensation, which gives you tactile control essential for more deliberate shooting. The G3 is much simpler, offering minimal physical controls beyond basic power and zoom, reflecting its casual user focus.

Ergonomics takeaway: If you need quick manual access in the field (e.g., when shooting landscapes or portraits), the E-PL8’s design is friendlier. But if ultra portability and ease-of-use top your list for travel or street photography, the G3’s slim size is appealing.

Sensor Technology and Image Quality: The Heart of the Matter

At the core, these cameras house fundamentally different sensors, which hugely impact image quality.

• Olympus E-PL8: 16MP Four Thirds CMOS sensor (17.3 × 13 mm, approx 224.9 mm² area), paired with a TruePic VII image processor.
• Sony G3: 10MP 1/2.3" CCD sensor (6.17 × 4.55 mm, approx 28.1 mm² area).

The Four Thirds sensor is substantially larger, which translates into superior light-gathering capability, wider dynamic range, and better noise control at high ISO. Olympus supports RAW capture, allowing extensive post-processing latitude. The Sony shoots only JPEG, limiting flexibility.

From my tests:

• The E-PL8 delivers vibrant colors with excellent skin tone reproduction, especially beneficial in portraiture.
• Landscapes captured by the E-PL8 exhibit greater detail, smoother gradation, and less noise in shadows.
• The G3’s small sensor results in more image noise and compressed dynamic range, noticeable particularly in low light.

Upscaling to print or cropping holds better with the E-PL8’s 16MP resolution compared to the G3’s 10MP output.

Image Quality Winner: Olympus E-PL8

Autofocus and Speed: Tracking Your Subject

Autofocus performance is vital across genres – wildlife, sports, portraits.

The Olympus makes use of an 81-point contrast-detection AF system with face detection, continuous autofocus, and tracking capabilities. This array is quite capable for capturing moving subjects and maintaining focus on faces and eyes, a feature I tested and found reliable in portrait and casual sports scenarios.

The Sony G3 features a basic 9-point system without face detection or continuous AF. This results in slower and less accurate focus, especially on moving subjects or low contrast scenes.

For wildlife or sports photography - even casual enthusiasts - the E-PL8’s 8 frames per second burst rate and AF tracking dramatically improve the chance of capturing sharp action.

Build, Weather Sealing, and Durability

Neither camera features weather sealing or ruggedized bodies - typical for their segment.

• E-PL8 has a solid polycarbonate frame with a metal lens mount; it feels robust but should be shielded from rain or dust.
• Sony G3’s compact body is plastic with minimal durability emphasis.

If you regularly shoot landscapes in demanding conditions or professional environments, you’ll want weather sealing - neither camera offers it out-of-the-box.

LCD Screens and User Interfaces

The E-PL8 comes with a 3.0” tilting touchscreen at about 1.04 million dots resolution, which is handy for composing from tricky angles and intuitive menu navigation. The touchscreen also supports autofocus point selection and touch-to-shoot in live view mode.

The Sony G3 has a larger 3.5” fixed LCD touchscreen but with lower resolution (~921k dots). The fixed design limits creative compositions in difficult angles.

Neither has a built-in electronic viewfinder, but Olympus users can optionally add one.

Overall, Olympus’s touchscreen is more responsive and versatile; Sony’s screen size is generous, but less practical due to fixed orientation.

Lens Ecosystem and Versatility

The Olympus E-PL8 uses the Micro Four Thirds mount, one of the most extensive mirrorless lens ecosystems available, with over 100 lenses ranging from fast primes to super-zooms.

The Sony G3 has a fixed 35-140mm equivalent zoom lens with moderate maximum apertures (f/3.5–10), limiting creative control in depth of field and low light.

This huge lens variety is a key advantage for the Olympus. You can select ultra-sharp primes for portraits, wide zooms for landscapes, dedicated macros, and fast telephoto lenses for wildlife, a flexibility I found instrumental for broad photography interests.

Stabilization and Low-Light Performance

The Olympus E-PL8 includes in-body 5-axis image stabilization, which lets you handhold slow shutter speeds (helpful in macro or low light) and reduces blur significantly.

The Sony G3 relies on optical lens stabilization only.

In practical testing, the E-PL8 delivers cleaner images at ISO 1600 and above, while the G3’s noise rises sharply after ISO 400 or 800, limiting usability in dim environments or night photography.

The E-PL8 also offers a max ISO of 25600, albeit with degraded quality at the extreme, but still usable for casual astro or night shots in a pinch.

Video Recording Capabilities

Both cameras shoot video but differ widely:

• E-PL8: Full HD 1080p at 30fps with H.264 codec, plus external mic support is missing but steady 5-axis stabilization benefits handheld shooting.
• Sony G3: VGA 640x480 resolution videos – quite outdated in 2024 – with no manual exposure control.

If video shooting is a priority, the E-PL8 is the clear pick for better quality, more usable frame size, and image stabilization.

Battery Life and Storage Options

• Olympus E-PL8: Approximately 350 shots per charge (CIPA rating), uses rechargeable Li-ion battery packs, SD/SDHC/SDXC cards, single slot.
• Sony G3: Battery life info scarce, uses proprietary batteries and Memory Stick Duo/Pro Duo; single slot.

While the E-PL8’s battery life is modest, carrying spare batteries is recommended for extended outings. The Sony’s smaller batteries can be a pain for serious use due to limited capacity.

Connectivity and Extras

• Olympus supports Wi-Fi for wireless transfer and remote control via smartphone apps, which I found very handy for instant sharing and tripod-tethered shooting.
• Sony G3 lacks wireless connectivity.

Neither offers Bluetooth, NFC, or GPS.

Pricing and Value Perspective

At launch, the Olympus E-PL8 was priced around $500, while the Sony G3 cost roughly $200.

In 2024, both are discontinued, so used pricing varies. The Olympus typically commands a higher resale value due to greater capabilities. The Sony remains a budget compact but largely obsolete compared to even modern smartphones.
