Olympus E-PL3 vs Sony A6300: A Photographer’s Guide to Choosing Your Next Mirrorless Camera

In the ever-evolving world of mirrorless cameras, choosing the right body is crucial not just for image quality but for how well it fits your creative workflow and shooting style. Today, I’m diving deep into two cameras from different eras but both renowned in their segments - the Olympus PEN E-PL3 (2011) and the Sony Alpha a6300 (2016). Having spent extensive time testing both in diverse shooting environments, I’ll walk you through their strengths, weaknesses, and how each one performs across multiple photography disciplines, culminating in practical recommendations.

Before unpacking the nuanced differences, let’s set the stage by comparing their physical design and ergonomics.

Handling and Design: Compact Comfort Meets Modern Control

At first glance, the Olympus E-PL3 embraces the classic rangefinder-style with a petite, minimalist body, while the Sony A6300 opts for a slightly larger, more rugged build designed for advanced users.

The Olympus measures a compact 110x64x37mm and weighs a mere 313g body-only - a dream for travelers and street shooters who favor light packing. Its build, while modest, feels solid enough for casual use. The tilting 3-inch LCD with HyperCrystal tech delivers decent visibility, although its resolution at 460k dots feels dated by today’s standards.

In contrast, the Sony A6300 is a bit heftier at 404g, with a slightly more substantial footprint (120x67x49mm). It’s still pocketable but manages to incorporate a deeper grip and more ergonomic button layout designed with enthusiast photographers in mind. The 3-inch tilting LCD, boasting 922k-dot resolution, gives noticeably clearer preview and playback feedback. The A6300 also includes a high-res 2.36M-dot electronic viewfinder with 0.7x magnification and 100% coverage, which the Olympus lacks by default (it relies on an optional EVF accessory).

Looking at the control surfaces in more detail:

The Sony provides a dedicated mode dial, custom buttons, and exposure compensation dial - classic enthusiast fare giving speedy tactile access. Olympus E-PL3 keeps it simpler, with fewer dials, relying mostly on menus and fewer buttons. This might appeal to beginners but extends shot setup time for professionals.

The takeaway here: Olympus wins for ultra-compact portability and simplicity, while Sony edges ahead in control sophistication and handling comfort for longer sessions.

Sensor and Image Quality: Size, Resolution, and Real-World Output

One of the most defining differences between these cameras - and a key factor in ultimate image quality - is sensor size and resolution.

The Olympus E-PL3 wraps a 12MP Four Thirds sensor measuring 17.3x13mm. In the 2011 context, this sensor offered respectable output with decent noise performance at low ISO thanks to TruePic VI image processing. However, it is relatively small, so dynamic range and high ISO performance are limited. DxOMark gives this sensor an overall score of 52, with color depth around 20.9 bits, dynamic range of 10.3 EV, and low-light ISO score near 499.

The Sony A6300, by contrast, sports a much larger 24MP APS-C sensor (23.5x15.6mm) - over 60% larger sensor area. This not only allows higher resolution (6000x4000 pixels), but significantly better dynamic range and noise handling. Sony’s BIONZ X processor combined with advanced sensor design pushes the DxOMark score to 85, color depth at 24.4 bits, dynamic range of 13.7 EV, and low-light ISO sensitivity rating near 1437.

What does this mean practically? In my hands-on testing, landscapes and low-light scenes shot on the A6300 showed more detail, cleaner shadows, and richer gradients. Skin tones came out more natural and nuanced as well. The E-PL3’s Four Thirds sensor is fine for snapshots and web-sharing but struggles with shadow recovery and grain above ISO 800.

LCD and Viewfinder Experience: Seeing Your Shot Clearly

Back screen clarity and viewfinder options heavily influence shooting comfort, especially in bright outdoor conditions.

Despite being released 5 years apart, both cameras sport tilting 3-inch screens. However, Sony’s higher resolution LCD (922k dots vs Olympus’s 460k dots) produces noticeably sharper previews and easier menu navigation. The lack of touchscreen on both limits intuitive focus point selection, but the Sony’s more detailed view helps manual focusing and compositional precision.

The biggest gap? The Sony A6300’s built-in electronic viewfinder, which offers a bright, lag-free alternative to LCD composing, perfect in direct sunlight and for critical focus checking. Olympus users must buy the external VF-2 EVF - an additional cost and bulk - which is less integrated.

Autofocus and Performance: Speed, Accuracy, and Tracking

Both cameras feature hybrid autofocus systems, but the difference in underlying technology and processing power is stark.

The Olympus E-PL3 uses a contrast-detection AF system with 35 focus points. While it supports face detection and continuous AF, the AF speed can feel sluggish, especially in low light or fast-action scenes. Tracking moving subjects is an uphill battle and hunting under tricky lighting is common.

Sony’s A6300 employs a highly advanced hybrid AF with 425 phase-detection points distributed almost across the entire frame. From my extensive testing, this means quick acquisition, consistently accurate locking, and very effective subject tracking - even in rapidly changing scenes like sports or wildlife. The continuous shooting speed of 11fps (vs the Olympus’s 6fps) further empowers capturing decisive moments.

Whether panning for runners or catching birds in flight, the Sony’s AF system provides an edge few cameras in this category achieve. Olympus, while reliable indoors or for still subjects, falls short here.

Photography Disciplines: Strengths and Suitability

Now that the technical underpinnings are clear, let’s explore how these translate across major photography genres.

Portraits: Skin Tones, Bokeh, Eye Detection

Portraiture demands pleasing skin tone rendition and smooth subject-background separation.

The Olympus produces warm, pleasant skin tones but with noticeably lower resolution and softer bokeh due to smaller sensor size and the typical limited aperture of kit lenses. Face detection AF works but lacks eye-detection refinement.

Sony’s APS-C sensor combined with a larger selection of fast lenses creates creamy bokeh and more lifelike skin textures. Eye autofocus, even if not present in earlier firmwares, can be partially supplemented by spot AF combined with face detection, yielding sharper eyes in headshots.

Landscapes: Dynamic Range and Resolution

Landscape photography benefits from high resolution and dynamic range to capture subtle tones and detailed scenery.

The Olympus E-PL3’s lower dynamic range means highlights or shadows clip earlier, reducing latitude for editing. The 12MP sensor is adequate but limiting if you want big prints or heavy cropping.

Sony’s A6300 offers much more flexibility and detail, with richer files that withstand harsh editing and present complex scenes more naturally. It’s also weather-sealed - an important advantage when shooting outdoors in changing conditions.

Wildlife and Sports: Autofocus and Burst Performance

These genres require fast, precise autofocus and high frame rates.

Olympus’s contrast-detect AF drags behind in speed and tracking, limiting success to slower or less erratic subjects.

The Sony’s 425-point hybrid AF and 11fps burst make it a potent tool for wildlife and sports. Add in excellent ISO performance and you have a camera that excels from dimly lit stadiums to forest underbrush.

Street and Travel Photography: Size, Discretion, and Battery Life

Street photographers often prize discretion and portability.

The Olympus E-PL3 shines here with its small size and light weight, allowing unobtrusive shooting and longer carrying comfort. The 300-shot battery life is average but manageable.

The Sony is larger and heavier, which might be noticeable during all-day walks. The longer 400-shot battery helps on longer trips, but the bigger body changes the feel. Still, for an advanced traveler wanting versatility with better image quality, the A6300 offers a strong package.

Macro and Night/Astro Photography

Neither camera specializes in macro, but Olympus’s sensor-stabilization aids handheld close-ups modestly, whereas Sony relies on lens IS or tripod use.

For night and astro photography, the Sony clearly outperforms thanks to excellent high ISO performance and broader dynamic range. This means lower noise and better star detail. Olympus users will find noise increasingly intrusive at high ISOs.

Video Capabilities

Olympus E-PL3 delivers Full HD video up to 1080p at 60fps, recorded in AVCHD or Motion JPEG. However, it lacks an external mic input or advanced video features, limiting usability for dedicated videographers.

Sony A6300 supports UHD 4K recording with flexible frame rates up to 120fps in Full HD, plus microphone input, providing a much more versatile video experience.

Build Quality and Weather Resistance: Durability Considerations

Sony’s A6300 includes weather sealing to resist moisture and dust, which is a meaningful benefit if you shoot in challenging environments. Olympus E-PL3 lacks any sealing, making it more vulnerable outdoors.

Lens Ecosystem and Compatibility

Both cameras share access to rich lens ecosystems via their mounts:

• Olympus E-PL3: Micro Four Thirds system has a mature lineup with over 100 lenses, including compact primes, macro, and wide zooms. The 2.1x crop factor turns telephotos into reach-extenders but also limits wide-angle perspectives.

• Sony A6300: Sony’s E-mount features over 120 lenses, including APS-C optimized and full-frame glass, offering more high-quality primes and fast zooms. The 1.5x crop factor provides a nice middle ground between reach and wide coverage.

Each system offers excellent lens options for various needs, though Sony’s greater breadth and fast lens availability often attracts advanced users.

Connectivity, Storage, and Battery

The Olympus E-PL3 offers no built-in wireless connectivity, relying on cables for image transfer - a limiting factor for modern shooting workflows. Its SD/SDHC/SDXC single card slot is standard.

Sony improves on this significantly, providing built-in Wi-Fi and NFC for on-the-go sharing and remote control, important for today’s connected photographers.

Battery life favors Sony (400 vs 300 shots), and though both use proprietary packs, the Sony NP-FW50 is well-known and widely available.
