Sony RX10 III vs Sony A68: Which Camera Fits Your Photography Style?

When it comes to choosing your next camera, especially from within one manufacturer’s lineup, the decision can be tricky. Sony’s Cyber-shot DSC-RX10 III and the SLT-A68 cater to different crowds - but given their overlapping features and pricing gaps, they’re often compared by enthusiasts and pros on tighter budgets. I’ve spent extensive time with both cameras under varied shooting conditions, and in this deep-dive comparison, I’ll help you understand how these two cameras stack up across all major photography disciplines, technical attributes, and everyday usability factors.

Let’s unpack their differences, nuances, and real-world performances to help you pick the best fit for your needs and style.

A Tale of Two Cameras: What Are We Comparing?

Before jumping into the nitty-gritty, here’s the elevator pitch for both:

• Sony RX10 III: Introduced in 2016 as a premium large-sensor superzoom bridge camera, it offers a fixed 24-600mm equivalent f/2.4-4 lens, with a 1" BSI-CMOS sensor, excellent optical stabilization, and rugged yet portable handling. The RX10 III aims to deliver pro-level versatility in a single body - no lens swapping required.

• Sony A68: Launched in late 2015, the A68 is branded as an entry-level APS-C DSLR-style camera. Sporting a 24MP APS-C sensor and Sony’s SLT phase-detect autofocus with 79 focus points, it’s a more traditional interchangeable-lens camera targeted at enthusiast beginners and budget-conscious hobbyists.

Both cameras use Sony's Bionz X processor, have tilting LCD screens, and electronic viewfinders, but their core philosophies and specifications diverge sharply once you look closer.

Above, you can see the physical size difference - the RX10 III is chunkier and more robust than the more compact A68. Ergonomics-wise, both cameras offer excellent grips, but the RX10’s integrated zoom lens adds bulk and weight (about 1051g vs 610g), which is an important consideration for portability and travel. The A68’s DSLR-style control layout feels closer to traditional DSLRs, while the RX10 III's SLR-like bridge design strikes a balance between compactness and functionality.

Sensor and Image Quality: Size Matters (But Not Always)

The heart of any camera is its sensor, and here we have two fundamentally different beasts:

• Sony RX10 III: 1” BSI-CMOS sensor, 20MP resolution, sensor size 13.2 x 8.8mm (116.16 mm² area)
• Sony A68: APS-C CMOS sensor, 24MP resolution, sensor size 23.5 x 15.6mm (366.6 mm² area)

Clearly, the larger APS-C sensor in the A68 offers a significant edge in light-gathering capability, dynamic range, and low-light performance. According to DxO Mark benchmarks (which I trust for sensor evaluation), the A68 scores 79 overall compared to 70 for the RX10 III, with notable advantages in color depth (+1 bit) and dynamic range (+0.9 EV).

In practical shooting, this translates to:

• Better noise control and cleaner images at higher ISOs on the A68, making it a stronger choice if you're shooting events, low-light portraits, or astrophotography.

• The RX10 III’s 1” sensor is no slouch, though; it delivers sharp, punchy JPEGs and can output impressively detailed files for a superzoom bridge camera, especially in good lighting. The BSI (backside illuminated) design helps with mid-range ISO performance.

Both cameras shoot RAW, which I tested extensively using Adobe Lightroom. The A68’s RAW files offered greater latitude for recovery and tonal gradation, especially in shadows.

Autofocus and Burst: Tracking the Action

Moving subjects are a beast of their own. Which of these two cameras handles them better?

• Sony RX10 III: Contrast-detection AF with 25 points, including face detection. Max burst rate of 14 fps.

• Sony A68: SLT phase-detection autofocus with an impressive 79 focus points, including 15 cross-type points, and burst rate up to 8 fps.

While 14 fps sounds fast on the RX10 III, keep in mind it uses contrast detection, which is generally slower and less accurate for tracking fast-moving subjects. The A68 uses Sony’s SLT (translucent mirror technology) to offer traditional phase-detection autofocus directly from the sensor, which dramatically enhances subject tracking and continuous focus.

In practical terms, I found the A68’s autofocus better suited for:

• Wildlife and sports photography, where tracking erratic subjects requires precision and speed.

The RX10 III’s excellent zoom range means it’s still a contender for wildlife telephoto shots, but autofocus hunting (searching for focus) can become frustrating with fast animals or unpredictable sports action.

Build Quality, Weather Sealing, and Durability

Both cameras are well-built, but… one stands out:

• The RX10 III features environmental sealing, weather resistance against dust and moisture, and generally rugged construction.

• The A68 lacks weather sealing, though it’s robust for a budget-oriented DSLR-style body.

If you find yourself shooting outdoors frequently - think landscape hikes, wildlife expeditions, or rainy street photography - the RX10 III’s weather sealing can be a lifesaver.

Ergonomics and User Interface: Direct Control vs. Portability

Looking at the top view, the RX10 III sports direct dials for aperture, shutter speed, ISO and exposure compensation - all ergonomically arranged. Its electronic viewfinder is high-resolution (2.35M dots) with 100% coverage and 0.7x magnification, which offers a bright, detailed framing experience.

The A68 has a traditional DSLR layout, with solid controls and a slightly lower resolution EVF (1.44M dots, 0.57x). The LCDs on both tilt for versatile angles but the RX10 III’s 3-inch screen is higher resolution and more responsive.

Neither has a touchscreen, which is a bit limiting in 2024 but expectable for their release periods.

In use, I preferred the RX10 III for quick outdoor adjustments and operational speed, while the A68’s menu system feels familiar for DSLR users migrating to Sony.

Lens Ecosystem and Versatility: Fixed Zoom vs. Interchangeable Freedom

This may be the single biggest practical difference:

• The RX10 III has a fixed 24-600mm equivalent zoom lens with fast apertures from f/2.4 to f/4. The lens covers everything from wide-angle landscapes to distant wildlife telephoto.

• The A68 accepts Sony’s A-mount lenses - a broad lineup of 143 lenses including fast primes, zooms, macro lenses, and specialized glass.

If you want the convenience of “one and done” - an all-rounder you don’t have to carry multiple lenses for - the RX10 III is brilliant. Its image stabilization also shines at extreme telephoto settings.

However, if you value expanding your creativity with specialized optics or already have A-mount glass, the A68’s lens compatibility will serve you better in the long run.

Battery Life and Storage

Here’s a practical reality check: how many shots and how long can you shoot?

• A68 boasts a stronger battery life rating: approximately 510 shots per charge (CIPA standard).

• RX10 III rated at around 420 shots per charge.

The A68’s larger battery and lighter body give it a measurable advantage for day-long shoots without bringing spares.

Both cameras use SD cards (RX10 III supports SDHC, SDXC, Memory Stick), with a single card slot each.

Connectivity and Extras

In a world increasingly synced to smartphones and laptops:

• The RX10 III offers built-in Wi-Fi and NFC for speedy image transfer and remote control apps. It has both microphone and headphone ports, a plus if you value video recording.

• The A68 supports Eye-Fi card connectivity (a more dated wireless solution) and has a microphone input but lacks headphone support or NFC.

For vloggers, hybrid shooters, or video creators, the RX10 III’s robust connectivity suite gives it extra appeal.

Video Capabilities: Hybrid Shooter’s View

Both cameras shoot Full HD 1080p video, with the RX10 III pushing into 4K UHD recording (3840 x 2160 at up to 30p), something the A68 does not support.

The RX10 III’s lens and sensor combination, plus its optical image stabilization, produce smoother footage at longer zooms - a big advantage for documentary or travel videographers who don’t want to carry a separate camcorder.

The A68 is serviceable for basic video but feels dated compared to modern hybrid standards.

Real-World Testing Across Photography Genres

Here’s where experience matters. I evaluated both cameras across key genres you care about.

Portrait Photography

The A68’s larger sensor delivers better skin tone richness and shallow depth of field for isolating subjects, especially at standard portrait lenses (85-135mm equivalent on APS-C).

The RX10 III’s lens at f/2.4 offers pleasing bokeh at wide focal lengths, but its 1” sensor can’t quite replicate the creamy background blur or dynamic tonal range of the A68.

Both feature face detection AF, though the A68’s 79-point system tracks eyes more accurately.

Landscape Photography

Dynamic range is king for landscapes. The A68’s better range (13.5 EV vs 12.6 EV) allows for cleaner shadow highlights and better midtone separations.

The RX10 III’s flexibility to frame wide to telephoto without swapping lenses is helpful for compressing scenes and isolating landscape elements.

Weather sealing gives RX10 III an edge for inclement outdoor conditions.

Wildlife Photography

The RX10 III’s 600mm reach is incredibly tempting - little can beat that zoom convenience. However, its contrast-detection AF lags behind the A68’s phase-detection system when tracking erratic animal movement.

So for rare wildlife bursts or action, I prefer the A68 paired with a dedicated telephoto lens. But for casual zoom wildlife photography, the RX10 III is fantastic.

Sports Photography

Here the A68's 79 AF points and phase detection shine brightest. Tracking fast-moving athletes becomes manageable, paired with solid frame rates (8 fps).

The RX10 III, while faster in continuous shooting theoretically, suffers autofocus lag outdoors during action-heavy moments.

Street Photography

Despite the RX10 III’s zoom versatility, the A68 wins hands down for portability and discretion. Smaller, lighter, and less “camera-like” in size, it’s easier to be unobtrusive.

Also, the A68’s faster startup and quieter shutter help keep you inconspicuous.

Macro Photography

The RX10 III macro focus distance of 3cm allows for impressive close-ups with natural bokeh in one package. The fixed lens with excellent sharpness across frame gives you consistent macro capability.

The A68’s macro result depends on the lens you choose; pairing it with a dedicated macro lens yields superior magnification and working distance, which can be a deciding factor for pros.

Night and Astro Photography

A68’s higher max ISO (25600 native) and better noise performance give it the nod here. Long exposures coupled with its dynamic range let you pull stars and shadows with less noise.

The RX10 III is capable in lower light but hits noise earlier.

Travel Photography

Portability and versatility collide here. The RX10 III’s fixed 25x zoom lens means you can leave lenses at home, reducing gear bulk - but it’s heavier.

The A68’s lighter body and interchangeable lenses offer flexibility but require carrying multiple lenses, meaning more weight and longer prep.

Battery life favors the A68 for long travel days.

Professional Work

Neither is a full professional tool - no pro-grade durability or full-frame sensors here.

That said, the RX10 III’s weather sealing and robust video features make it suitable for fieldwork with minimal lens changes.

The A68’s RAW files and lens ecosystem make it better integrated into DSLR workflows for studios or event shooters on a budget.

Final Scores and Summary

Key takeaway: The A68 edges out overall image quality and autofocus performance, while the RX10 III shines in versatility, zoom reach, and rugged handling.

• Action, sports, or wildlife with precise AF tracking is your jam.
• You prefer lighter gear for discretion in street or travel photography.
• Budget is tight, and you want DSLR-style controls with plenty of tech features.

Personal Final Thoughts

I often lean toward cameras with the larger sensor and better autofocus when image quality and subject tracking are priorities, so the A68 holds strong appeal for me where versatility and interchangeable lenses are desired.

However, the RX10 III’s zoom range and rugged build make it a sort of Swiss Army knife I find invaluable when the goal is “one camera for everything.” It’s truly remarkable how much that fixed lens covers, and its quiet operation and durable design have saved shoots in bad weather.

Both cameras are excellent tools, but for very different users.

Wrapping it Up: Making the Right Choice for You

In the ever-evolving camera market, these two represent distinctly different approaches: versatility with a fixed zoom vs. flexibility with interchangeable glass.

Ask yourself:

• Do you need absolute zoom reach and weather resistance in one package?
• Or would you rather invest in larger sensor image quality and an extensive lens ecosystem?
