Olympus E-PL5 vs Sony A390: An Expert Hands-On Comparison for Photography Enthusiasts

Choosing between the Olympus PEN E-PL5 and the Sony Alpha DSLR-A390 might seem straightforward given their clear category differences - mirrorless versus DSLR - but beneath the surface lie nuanced strengths and trade-offs that affect everything from image quality to ergonomic comfort. Having tested thousands of cameras across genres and workflows, I’m eager to unpack how these two fare side-by-side, diving deep into their core technologies, performance in real-world scenarios, and suitability across photography disciplines.

Let’s dive in, giving you a clear, experience-driven picture so you can make the best decision for your shooting style and creative ambitions.

First Impressions: Size, Build, and Handling Comfort

Right out of the gate, you’ll notice the Olympus E-PL5 is a significantly more compact and lightweight camera compared to the Sony A390. The PEN’s rangefinder-style mirrorless design measures a trim 111 x 64 x 38 mm and weighs just 325 grams with the battery - a camera you can comfortably slip into a jacket pocket or petite bag.

The Sony A390, on the other hand, embraces the heft of a compact DSLR body at 128 x 97 x 86 mm and 549 grams, demanding a larger grip and more space in your kit.

Handling matters: the E-PL5’s slim profile with a gently tilting 3-inch touchscreen invites quick framing and intuitive menu navigation, even for beginners. The Sony’s traditional DSLR shape fits well in larger hands, but its deeper grip and physical controls feel more familiar to shooters versed in DSLRs, though its 2.7-inch display lacks touchscreen finesse.

If you prioritize portability and discreetness for strolls or travel, Olympus has the edge; if you want a more substantial grip and classic DSLR feel, Sony will appeal.

Design and Control Layout: Where Usability Meets User Preference

Looking down at the top panel, both cameras keep things simple but with contrasting philosophies.

The E-PL5’s minimalist top plate features a mode dial, a shutter button surrounded by on/off toggle, and a few knobs for quick adjustments. The touchscreen on the back completes the interface, supplementing physical controls. This minimalism means beginners might find adjusting exposure or white balance settings less intimidating while maintaining enough options for enthusiasts.

Sony’s A390, by comparison, sticks to tradition with dedicated exposure compensation and mode dials, plus more physical buttons dedicated to ISO, metering, and autofocus modes. There's no touchscreen - menus require navigation via buttons and directional pads, which can slow you down but offer tactile reassurance, especially in bright sunlight when screens glare.

For intuitive, modern handling with touch interface, Olympus wins here; for more traditional manual control access, Sony holds ground.

Sensor and Image Quality: The Heart of the Matter

Both cameras depart significantly on sensor tech and size, which shapes image quality, noise performance, and field of view.

The E-PL5 boasts a 16-megapixel Four Thirds (17.3 x 13 mm) CMOS sensor, whereas the A390 utilizes a 14-megapixel APS-C (23.5 x 15.7 mm) CCD sensor. While Sony’s APS-C sensor is roughly 64% larger in surface area, it’s an older CCD design, overshadowed by modern CMOS tech’s efficiency and low-noise characteristics.

In testing under controlled studio conditions and challenging low-light scenarios, the Olympus sensor’s CMOS architecture delivers cleaner files at higher ISOs, with a DxO Mark low-light ISO rating near 889, outpacing Sony’s CCD-based 607. Dynamic range - key for landscapes and portraits - also tips slightly to Olympus’s 12.3 EV versus Sony’s 11.5 EV, yielding more retained highlight and shadow details.

Color depth scores are comparable (roughly 22.8 bits for Olympus vs 22.5 bits for Sony), meaning both deliver vibrant, nuanced color rendition, but Olympus’s sensor clarity and reduced noise have a practical edge when pushing files in post-processing.

That Four Thirds sensor size paired with a 2.1x focal length multiplier translates into a tighter field of view - telephoto prone - while Sony’s APS-C 1.5x crop offers a middle ground suited for versatility.

Ultimately, Olympus edges out Sony for cleaner, more detailed images at higher ISOs, important for portraits, events, and low-light shooting. Sony’s APS-C sensor remains respectable, especially for daylight landscape and everyday use.

Viewing Essentials: Screen and Viewfinder Differences

For framing your shot, the E-PL5 leverages a sharp 3-inch tilting touchscreen LCD with 460k dots resolution, enhancing live view accuracy and menu quick-taps. The Sony A390 offers a smaller, 2.7-inch tilting LCD at 230k dots with no touchscreen.

The E-PL5’s touchscreen responsiveness - particularly notable for face detection autofocus activation and quick exposure compensation - is a modern delight that speeds up workflow. Sony’s screen feels a bit dated, less sharp, and requires more button presses to adjust settings.

Neither camera includes a built-in electronic viewfinder, but the A390 provides an optical pentamirror with 95% coverage and a magnification of 0.49x. This viewfinder offers a natural, zero lag experience unavailable on Olympus's E-PL5 unless you add the optional VF-2 electronic viewfinder accessory. For bright daylight shooting or fast action, I often found the Sony optical viewfinder reassuring and sharp, though its 95% coverage means you might crop slightly when composing.

If you prefer an immersive direct-through-the-lens view and rely on a DSLR style, the A390 keeps the advantage here. If you value more flexible live view, face detection, and touch control, Olympus delivers a more contemporary experience.

Autofocus System and Speed: Tracking Life in Motion

Autofocus performance is pivotal for action, wildlife, or street shooters who can’t afford missed shots.

Olympus’s Forty-five contrast-detection AF points, including face detection and live view autofocus, deliver quick, reliable focusing with continuous autofocus and tracking modes. Though lacking phase detection (common in more recent mirrorless models), the E-PL5’s system impressed me with its snappiness and accuracy in varied lighting.

Sony’s A390 features an older 9-point phase detection AF system augmented by center-weighted metering. Its continuous autofocus is adequate but noticeably slower in live view mode since it falls back on contrast detection there. The physical DSLR phase detection works well for static or moderately moving subjects; however, it trails Olympus in continuous tracking fluidity, especially in live view or video.

Continuous shooting shoulder-to-shoulder reveals Olympus’s faster 8 fps burst capability versus Sony’s more pedestrian 3 fps - advantageous for burst-heavy wildlife or sports photography.

Summing up, Olympus offers a more modern, flexible AF suited for live view, video, and rapid sequences. Sony’s phase detection excels in traditional viewfinder shooting but feels lethargic when using live view.

Shooting Across Genres: Practical Performance Breakdown

Now, let's get into how these cameras perform in various photography disciplines, observing both real-world use and technical merits.

Portraits: Skin Tones and Bokeh Quality

Portrait shooters need accurate skin tone rendition, creamy out-of-focus backgrounds, and confident eye detection autofocus.

Thanks to the Four Thirds sensor’s resolution and Olympus’s warm color calibration, the E-PL5 produces natural-looking skin tones with slightly richer color reproduction compared to the Sony A390’s CCD sensor, which sometimes rendered skin with cooler tonal shifts – typical of older CCDs.

The Olympus’s in-body image stabilization (IBIS) helps mitigate minor shakes allowing slower shutter speeds for sharp facial details, even in softer light. While neither camera boasts particularly wide maximum apertures out of the box, the micro four thirds lens available lens ecosystem offers many fast primes (like the Panasonic 42.5mm f/1.7) which deliver respectable background separation and pleasing bokeh.

Sony’s APS-C sensor naturally yields a shallower depth of field at equivalent focal lengths, appealing to portraitists craving separation, but with fewer wide-aperture native lenses compatible with the A390’s alpha mount, options are less plentiful without stepping into third-party territory.

Face detection autofocus on Olympus’s live view notably locks onto eyes with impressive precision, making it easier to focus critical portrait shots - something Sony tried but didn't quite nail here.

Landscape Photography: Dynamic Range and Resolution

High dynamic range and resolution are crucial for capturing the full tonal spectrum from shadows to highlights.

With a slight edge in rated dynamic range and higher native ISO ceilings, Olympus’s E-PL5 pulls ahead in retaining shadow details in challenging lighting, while its 16MP sensor provides ample resolution for large prints or cropping.

Sony’s APS-C 14MP sensor, though larger, offers similar pixel count but falls short in handling high-contrast scenes due to its CCD noise profile and lower maximum ISO.

Neither camera offers built-in weather sealing, a drawback for dedicated landscape shooters exposed to elements; however, Olympus’s smaller body and lighter lenses make it easier to hike longer distances.

Wildlife and Sports: Autofocus Speed and Burst Rates

Wildlife and sports demand fast, accurate autofocus and rapid shooting to track fast action.

Here Olympus’s 8 fps burst combined with contrast-detect AF and tracking delivers more keeper frames in quick sequences than Sony’s 3 fps with 9-point phase detection AF.

Lens availability also matters - Sony’s alpha mount offers a wider selection of long telephotos ideal for wildlife, but the heavier, bulkier lenses reduce overall portability compared to Olympus’s lighter micro four thirds lenses (albeit with crops to consider).

If you intend on heavy action shooting, the E-PL5’s speed advantage leans in your favor but be mindful of autofocus reliability in extremely fast-moving subjects, where neither could fully match higher-end models.

Street and Travel Photography: Discreetness and Mobility

Street and travel photographers often favor light, quiet, and unobtrusive cameras to capture candid moments.

Olympus’s pocketable size, silent shutter mode, and tilting touchscreen for low-angle or overhead shots make the E-PL5 a natural choice. The built-in sensor-based image stabilization adds confidence for handheld shots in tricky light.

Sony’s bulkier DSLR design with its louder shutter and mirror slap draws more attention; however, its optical viewfinder and solid build provide a more traditional street shooting experience if certain you want an SLR feel.

Battery life heavily favors Olympus (approximately 360 shots vs Sony’s 230), crucial for extended travel days without charging options.

Macro Photography: Focus Precision and Stabilization

Macro enthusiasts will appreciate precise focusing and stabilization to reveal detail in small subjects.

While neither camera is specialized for macro, Olympus’s in-body image stabilization helps handhold macro shots without blur, especially paired with macro primes from its lens pool.

Sony’s less sophisticated stabilization and lower burst rate limit its macro utility slightly; however, shooting through the optical viewfinder assists more stable compositions.

Video Capabilities: Shooting Beyond Still Images

Olympus E-PL5 offers basic Full HD 1080p video at 30 fps, with H.264 and Motion JPEG formats. It lacks external microphone input but includes in-camera stabilization aiding handheld video.

Sony A390 does not support video recording at all - a deal breaker if you want hybrid photo-video usage.

For casual or beginner videographers who want smooth footage in a lightweight package, Olympus is the clear winner.

Lens Ecosystem and Compatibility: Flexibility Meets Investment

Sony’s Alpha DSLR mount has a legacy dating back to Minolta, offering roughly 143 native lenses including many third-party options from Tamron, Sigma, and Zeiss. This abundance suits beginners to professionals seeking specialized glass.

Olympus’s E-PL5, with its micro four thirds mount, supports over 100 lenses from Olympus and Panasonic. Despite smaller sensor format, MFT lenses tend to be more compact, lightweight, and affordable.

Both systems boast excellent prime, zoom, macro, and specialty lenses, but the lens size and weight difference become a deciding factor for portability.

Ergonomics and User Interface: Usability Over Long Shoots

Ergonomics are a subjective but important component.

Olympus’s lighter, smaller design suffers a bit from the lack of an integrated viewfinder, requiring reliance on the rear touchscreen for composition, which is well balanced and responsive. Button placement is minimalist but accessible.

Sony’s bigger DSLR body offers a better physical grip for larger hands, multiple dedicated buttons for faster setting changes, and an optical viewfinder favored by traditionalists.

For shooting extended sessions, wrist fatigue may favor Olympus for casual strolls and travel, Sony for robust studio or hourly sessions.

Connectivity, Battery Life, and Storage: Staying Powered and Connected

Olympus includes Eye-Fi wireless connectivity for transferring images via SD card, USB 2.0, and HDMI out. Battery life rates at about 360 shots per charge on the BLS-5 battery.

Sony lacks wireless but offers USB 2.0 and HDMI. The A390’s battery life is shorter, around 230 shots per charge, which might frustrate extended outings.

Both accept SD cards, with Sony also supporting Memory Stick Duo, a mostly legacy format.

Price and Value: Balancing Budget with Features

At approximately $399 for Olympus E-PL5 and $499 for Sony A390 (at initial launch), the Olympus offers newer tech, video recording, higher burst speed, and a smaller package for less money.

Sony’s DSLR experience, larger sensor, and optical viewfinder come at a slightly higher cost but with older CCD sensor technology and less versatile autofocus/live view.
