Panasonic Lumix DMC-G6 vs Sony SLT-A68: A Hands-On Comparison for Enthusiasts and Pros

When selecting a camera that balances affordability with versatile performance, it's vital to look beyond specs and marketing promises. Over the years, I’ve tested and reviewed more than a thousand cameras, so I approach comparisons with a practical, no-nonsense perspective. Today, we dive deep into the Panasonic Lumix DMC-G6 and Sony SLT-A68 - two entry-level contenders from different camps and sensor sizes, serving photographers looking for solid image quality, competent autofocus, and ergonomic controls for various disciplines.

Both models come from an era when mirrorless systems were challenging DSLR dominance, making them fascinating case studies in tradeoffs between sensor size, design philosophy, and features. Let’s unpack their real-world strengths and weaknesses so you can decide which suits your photographic ambitions.

At a Glance: Size, Ergonomics, and Handling

First impressions matter, especially when you hold a camera for hours in the field. The Panasonic G6, being a mirrorless Micro Four Thirds system, is significantly more compact and lightweight compared to the larger Sony A68 DSLR body.

• Panasonic G6: Weighing just 390 grams and measuring 122x85x71mm, the G6 feels nimble and travel-friendly. Its SLR-style mirrorless design combines a lightweight body with a sturdy grip and easily reachable controls.
• Sony A68: At 610 grams and a more robust 143x104x81mm, the A68 is noticeably heavier. It banks on traditional DSLR ergonomics, with a deeper hand grip and larger body that some shooters associate with professional handling.

Ergonomically, the G6’s smaller size is great for street and travel photography when portability matters, but those used to DSLR heft may find the A68’s grip more confidence-inspiring, especially with larger lenses.

Looking at the top control layouts:

• Panasonic steps it up with a fully articulated touchscreen for versatile framing, live view shooting, and easy menu navigation.
• Sony’s tilting LCD is smaller and lower resolution, lacking touchscreen capability - a downside when quick focus adjustments or menu toggling are needed in the field.

Sensor Technology and Image Quality: Micro Four Thirds vs. APS-C

Here’s where the two diverge significantly - sensor size and resolution impact image depth, noise handling, and dynamic range.

• G6 Sensor: A 16MP Four Thirds sensor (17.3x13mm) with a 2.0x crop factor (effective focal length multiplier ~2.1x). Panasonic’s sensor is a decade old, with an anti-aliasing filter and solid performance in daylight.
• A68 Sensor: A newer 24MP APS-C sensor (23.5x15.6mm), delivering roughly 1.5x crop. Its larger surface area yields better detail, color depth, and lower noise at high ISO values.

Key Results from Hands-on Testing:

• The Sony A68 outperforms the G6 in dynamic range by roughly 2 stops (~13.5 vs 11.5 EV), offering more latitude for recovering shadows and highlights - crucial for landscape and bright outdoor shooting.
• The A68’s low light ISO capability is also superior (low light ISO score 701 vs. 639), meaning cleaner images at high ISO settings and better performance in dim environments.
• Color depth leans in Sony’s favor too (24.1 bits vs. 21.3 bits), producing richer, more nuanced tones particularly visible in portrait skin rendition.

That said, the G6's images remain respectable at base and mid ISOs, making it workable for hobbyists and casual shoots.

Autofocus and Performance in Action

Autofocus performance can make or break a shoot, especially for wildlife, sports, or fast-moving subjects.

• Panasonic G6 uses contrast-detection autofocus with 23 focus points. It supports touch AF on the tilting LCD, face detection, and has continuous AF for video.
• Sony A68 features a hybrid system with phase-detection on 79 points (15 cross-type), paired with contrast detection - a more sophisticated and faster setup.

In repeated practical tests:

• The Sony A68 provides noticeably faster, more reliable autofocus acquisition and tracking on moving targets. The 79 focus points with phase detection make it ideal for sports and wildlife shooters.
• Panasonic's contrast AF struggles mildly with rapid subject shifts, especially in low light or telephoto ranges.

Continuous shooting rates slightly favor Sony as well (8fps vs. 7fps), offering an edge when capturing decisive moments.

Prospective wildlife or sports photographers will appreciate the A68’s responsiveness, while the G6 is good enough for portraits and casual action shooting.

Build Quality and Weather Resistance

Neither camera is weather-sealed or designed for harsh conditions, but their build quality influences day-to-day durability.

• The Sony A68, built as a compact DSLR, feels sturdier in hand and is better suited for extended use under varying light and physical conditions.
• Panasonic’s lighter polycarbonate body on the G6 is functional but less rugged.

Both cameras lack dustproof or waterproof features, so additional protective gear is recommended for adventurous outdoor shoots.

User Interface and LCD Screens

User interface design impacts how comfortably and efficiently you operate the camera, especially when learning or working in dynamic environments.

• The G6’s 3-inch fully articulated touchscreen (1036k dots) shines for creative shooting angles, vlogging, selfies, and menu access. Touch AF and touch shutter functions are welcome convenience features.
• Sony’s 2.7-inch tilting screen (461k dots) is less vibrant, smaller, and, critically, non-touch. Navigating menus feels slower and less intuitive, which can frustrate users accustomed to touch operation.

Viewfinders are similar electronic OLED types with 1440k dots and full coverage, offering crisp framing and info overlays.

Lens Ecosystem and Compatibility

Lens choice profoundly affects your photographic flexibility.

• Panasonic G6 uses the Micro Four Thirds (MFT) mount, with over 100 lenses available from Panasonic, Olympus, and third-party makers. The mount supports a wide array from ultra-wide to telephotos and excellent macro options - all generally compact and affordable.
• Sony A68 uses the A-mount (Sony/Minolta Alpha), with 143 lenses available, including legacy Minolta glass and Sony optics. However, the A-mount is aging, with fewer new lenses released recently compared to Sony’s E-mount mirrorless line.

If you prioritize lightweight travel lenses, MFT’s system wins. For longer focal lengths and DSLR-style glass, the Sony A-mount has more options.

Battery Life and Storage

• Sony A68 shines with excellent battery life: around 510 shots per charge, ideal for multi-day shoots without recharge woes.
• Panasonic G6 provides roughly 340 shots, typical for mirrorless cameras but requiring more frequent battery swaps.

Both cameras use a single SD/SDHC/SDXC slot, but Sony supports Memory Stick Pro Duo cards as well, giving slightly more storage flexibility.

Connectivity and Extras

• Panasonic G6 includes built-in Wi-Fi with NFC, enabling easy wireless image transfer and remote control via mobile devices - a big plus for modern workflows.
• Sony A68 lacks Wi-Fi but supports Eye-Fi cards for wireless transfer, a less seamless option.

Neither model offers GPS, Bluetooth, or headphone jacks.

Video Capabilities

For shooters combining stills with video work:

• Both record Full HD 1080p video; Panasonic at 60fps progressive (better for smooth motion) and Sony at 60i interlaced.
• Panasonic supports touch AF in live view video recording, aiding focus pull; Sony lacks touch but has a slightly better codec (XAVC S on top of AVCHD).
• Both have external mic inputs but no headphone jacks, limiting audio monitoring.

Panasonic’s articulated screen and better live view AF make it a slightly better hybrid for casual videographers.

Specialized Use Cases and Genre Performance

Scoring Their Overall Performance

Based on comprehensive testing and measured metrics from DxOMark and field experience:

• Sony A68 rates strongly at 79 points - reflecting its larger sensor, better dynamic range, and autofocus.
• Panasonic G6 scores lower at 61, typical for older and smaller sensor mirrorless designs.

Vocals detailed strengths in genres, affirming A68’s edge in demanding fast-action and low-light scenarios, with the G6 offering solid entry-level capabilities and portability.
