Olympus PEN-F vs Sony Alpha DSLR-A390: An Expert Hands-On Comparison for Serious Photographers

In the world of interchangeable lens cameras, the choice between mirrorless and DSLR systems often boils down to nuanced trade-offs that reflect your shooting style, priorities, and budget. Today, we're placing under the microscope two cameras that cater to distinct segments but might appeal to the same enthusiast: the Olympus PEN-F, a stylish advanced mirrorless shooter released in early 2016, and the Sony Alpha DSLR-A390, a more budget-friendly entry-level DSLR launched in 2010.

Having spent hours testing and evaluating cameras across decades of photography gear, I bring insights that go beyond specifications sheets and marketing fluff. This detailed comparison will dissect these two models across sensor technology, ergonomics, autofocus, image quality, and real-world performance - helping you understand which aligns with your photographic ambitions.

Let's dive in by laying out the physical and ergonomic differences before delving into the all-important imaging features.

How These Cameras Feel and Handle: Size, Design, and Controls

The Olympus PEN-F stands out immediately with its sleek rangefinder-style mirrorless body - a form factor that blends vintage charm with modern usability. Compact yet solidly built, it sports a surprisingly comfortable grip for a Micro Four Thirds camera, which I appreciated during extended shooting sessions. In contrast, the Sony A390 adopts a traditional DSLR silhouette with a chunkier grip and a larger body footprint typical of its class and era.

Ergonomically, the PEN-F wins points for its compact dimensions (125x72x37mm) and light weight (427g including battery), which make it highly portable without sacrificing control placement. Olympus’s familiar design language means the dials and buttons feel intuitive, with the addition of a dedicated mode dial and customizable controls being particularly beneficial for quick adjustments.

Comparatively, the Sony A390 is bulkier (128x97x86mm) and heavier at 549g. Its DSLR heft lends to a confident grip, but the overall pocketability is diminished. The larger body also means it's less comfortable to carry for casual travel or street photography over a day.

Looking at the top controls reveals further distinctions: the PEN-F’s rangefinder styling is accented with artistic dials that emphasize manual control - a photographer’s tool through and through. The A390 relies on a more conventional DSLR layout, with fewer dedicated dials and a more menu-dependent approach.

Neither camera offers illuminated buttons, which slightly hampers low-light operation on both fronts, but the PEN-F’s simplified dial scheme partially compensates.

Bottom line on handling: If compactness and stylish ergonomics are priorities, the PEN-F feels like a thoughtfully designed system. The A390, while larger and less refined in feel, provides a traditional DSLR grip that some photographers may prefer for stability with big lenses.

Sensor and Image Quality: Seeing the World Through Different Glass

Sensor technology and size underpin the image-making capability of any camera. Here, the PEN-F and A390 adopt divergent approaches due to their respective design intentions.

The Olympus PEN-F utilizes a 20MP Four Thirds CMOS sensor (17.3x13 mm), processed by the TruePic VII engine. This sensor includes a low-pass filter (AA filter), which reduces moiré but slightly softens detail - a classic trade-off. The smaller sensor size brings a 2.1x crop factor, influencing field of view and depth of field characteristics.

On the other hand, the Sony A390 features a larger 14MP APS-C CCD sensor (23.5x15.7 mm) with a 1.5x crop factor. It eschews CMOS for CCD, a traditional sensor technology known for its color accuracy and tonal gradation but generally less dynamic range and high ISO performance relative to modern CMOS sensors.

Dynamic Range and Color Depth

Per DxO Mark benchmarks, the PEN-F scores an overall 74 points, boasting superior dynamic range (12.4 EV) and better color depth (23.1 bits) compared to the A390’s score of 66 with dynamic range at 11.5 EV and color depth at 22.5 bits. This implies the PEN-F captures more tonal information and color nuances - valuable for landscape and studio portrait photographers who demand subtle gradations.

High ISO and Low-Light Performance

The PEN-F's native ISO range extends from 200 to 25,600, enabling more versatility in low-light photography, with a DxO low-light score of 894 ISO equivalent - considerably better than the A390’s max ISO of 3200 and score of 607 ISO equivalent. The larger sensor area of the A390 helps retain some image quality, but the older CCD sensor tends to generate more noise at high ISOs.

Resolution Considerations

While the PEN-F has a higher resolution (20MP, max 5184x3888), the A390’s 14MP (4592x3056) is still sufficient for many practical uses. The PEN-F also offers multiple aspect ratios including 1:1, popular with creative shooters, giving more compositional freedom 'in-camera.'

In my shooting tests, the PEN-F’s images display greater sharpness, finer details, and richer color rendition - especially in challenging light or contrasty scenes. The A390 produces pleasing colors with less noise at lower ISO but struggles past ISO 800.

Autofocus System – Speed and Accuracy Under Pressure

Autofocus (AF) performance can make or break camera usability, especially in fast-paced shooting scenarios.

• Olympus PEN-F: Contrast-detection AF system with 81 selectable points. Features Face Detection and yes, reliable continuous AF for moving subjects. Focus bracketing and stacking enhance macro or landscape precision.

• Sony A390: Phase-detection AF with 9 points (center weighted), no face or animal-eye detection technology. Single AF modes dominate; continuous AF is limited, and no focus bracketing.

The PEN-F’s 81 AF points allow for versatile focusing compositions, while the A390’s limited 9 points restrict flexibility but maintains some stable tracking within the center. Contrast-detect autofocus tends to be slower than phase-detect in general, but Olympus’s implementation is optimized well enough to not feel frustrating.

In real-world wildlife or sports shooting, the PEN-F’s 10 fps burst with continuous AF is excellent, whereas the Sony’s 3 fps and limited AF tracking are more suited for static or slower subjects.

LCD and Viewfinder: What You See Matters

Equipped with a 3-inch fully articulated touchscreen LCD at 1,037k dots, the PEN-F offers a versatile and bright display for composing at unusual angles or shooting selfies. The touchscreen operation helps speed navigation and focus selection - something I valued during street photography walks.

In contrast, the Sony A390 sports a 2.7-inch tilting, non-touch display with just 230k dots resolution, making the rear screen less pleasant for image review or menu use.

The electronic viewfinder (EVF) of the PEN-F is well detailed, with 2.36 million dots, 100% frame coverage, and 0.62x magnification, enabling precise manual focusing and composition.

The A390 relies on a pentamirror optical viewfinder with approximately 95% frame coverage and somewhat lower magnification (0.49x). Optical viewfinders have zero lag and are preferred by some for natural viewing, but they lack exposure previews or overlay info that an EVF can provide.

Video Features: What Are You Really Getting?

Neither camera is a video powerhouse by today’s standards, but differences still matter to users.

• Olympus PEN-F: Full HD 1080p recording at up to 60 fps, with the ability to shoot slow-motion 720p. Offers common codecs like MPEG-4 and H.264, but no microphone input or headphone jack, limiting audio control. No 4K video or photo modes.

• Sony A390: No video recording capabilities at all.

Thus, if video is on your agenda, Olympus’s PEN-F is the clear choice, though it remains a basic hybrid, best suited for casual or supplemental filmmaking rather than professional video production.

Lens Compatibility and Ecosystem Depth

The PEN-F’s Micro Four Thirds mount benefits from a vast ecosystem of over 100 lenses from Olympus, Panasonic, and third-party manufacturers. This includes high-performance primes, fast zooms, and specialty optics covering macro, telephoto, and wide-angle needs.

Sony’s A390 uses the older Sony/Minolta Alpha mount, with around 143 compatible lenses. While extensive, including legacy glass, it’s not as widely supported by third-party manufacturers today and lacks modern autofocus integration with newer lenses.

For photographers wanting lens flexibility and future-proofing, the PEN-F offers a more modern, versatile system, especially for mirrorless adventurers who value compact lenses and electronically controlled apertures.

Battery Life and Storage Options

The PEN-F achieves around 330 shots per charge, slightly above average for mirrorless cameras with EVFs, courtesy of its efficient sensor and processor design.

The A390, being a DSLR, reaches about 230 shots per battery, which is lower than I expected. This underlines that despite larger bodies, some older DSLRs don’t deliver remarkable endurance. However, DSLRs generally allow more efficient live view usage and longer standby times in practice.

Both cameras rely on a single SD card slot, with the A390 also supporting Memory Stick Pro Duo formats - a Sony proprietary feature less relevant today. Storage flexibility favors the PEN-F’s support for faster SDXC cards, beneficial for its higher resolution and video files.

Durability and Weather Resistance

Neither camera offers environmental sealing, waterproofing, or shockproofing. The Olympus PEN-F has a robust metal body with a quality feel but no official weatherproof rating.

The Sony A390 is plastic-heavy with a typical consumer-grade finish. Both are built for standard photography conditions but require care in harsh environments.
