Olympus E-M1 vs Sony A390

Comparing the Olympus E-M1 and Sony A390: Which Camera Fits Your Photography?

Owning tested and reviewed thousands of cameras over the past decade and a half, I’ve learned that finding the right gear always depends on a clear-eyed look at how models perform in real-world scenarios, not just what their spec sheets claim. Today I’m diving into a detailed side-by-side comparison of two quite different yet popular cameras: the Olympus OM-D E-M1, a 2013 pro-level mirrorless stalwart, and the Sony Alpha DSLR-A390, an earlier 2010 entry-level DSLR. Both appeal to photographers on a budget but come from different design philosophies and technology epochs. Let’s unpack their strengths and weaknesses across varied photography disciplines, technical features, and user experience to guide you toward an informed choice based on your specific needs.

Size, Build, and Handling: First Impressions Matter

Picking up the Olympus E-M1 and Sony A390 side-by-side immediately highlights the difference in their eras and categories. The E-M1, though the lighter of the two at 497g, carries a compact SLR-style mirrorless body that Olympus designed with ergonomics and professional handling in mind. Its dimensions (130x94x63mm) are relatively modest yet robustly constructed with weather sealing - a big plus for shooting in rain or dusty environments. The grip feels solid, influenced by Olympus’s legacy in Micro Four Thirds cameras built for on-the-go use.

In comparison, the Sony A390 weighs in heavier at 549g and is chunkier (128x97x86mm) - typical of entry-level DSLRs of its time, emphasizing comfortable grips and a user-friendly layout over portability. The lack of environmental sealing, however, limits its reliability in harsher conditions, and the bulkier build makes extended handheld sessions a bit more taxing.

Tactile control is another arena where the Olympus flexes its muscles. The E-M1 sports a thoughtfully placed array of buttons and dials - tilting the camera slightly reveals a user-friendly top layout. Meanwhile, the Sony A390’s traditional DSLR control scheme is straightforward but more basic, reflecting its beginner-friendly target audience.

For travelers or street photographers prioritizing discretion and mobility, the E-M1’s smaller footprint might prove advantageous. Sports and wildlife photographers who rely on sturdiness and weather-proofing will also lean towards Olympus here, while the Sony caters more to beginner users learning DSLR ergonomics.

Sensor & Image Quality: Four Thirds vs. APS-C CMOS and CCD

At the heart of any camera is its sensor, dictating final image quality, dynamic range, and low-light performance. The Sony A390 has a 14MP APS-C sized CCD sensor (23.5x15.7mm), whereas the Olympus E-M1 sports a slightly smaller Four Thirds CMOS sensor (17.3x13mm) with 16MP resolution.

This difference in sensor size and technology underpins many of the imaging disparities we observe. APS-C sensors typically capture more light, translating into better dynamic range and less noise in low-light situations. However, the Olympus pairs its CMOS sensor with its TruePIC VII image processor, delivering solid color depth (23 bit) and an impressive dynamic range nearing 12.7 EV, as validated by DXOMark’s scores. The Sony's CCD sensor scores overall lower (66 vs. E-M1's 73), with less color precision and dynamic latitude (11.5 EV).

In practical terms, shooting landscapes or portraits outdoors, the Olympus will retain a wider tonal range in shadows and highlights. Its anti-aliasing filter, although traditionally considered a slight softener, coupled with in-camera noise reduction, results in clean and detailed images. The Sony’s CCD sensor provides decent sharpness but is less forgiving in high-contrast scenes, with highlights clipping sooner.

Another critical factor is the crop factor: Olympus uses the Four Thirds system with a 2.0x crop, while Sony’s APS-C sensor has a 1.5x crop. This influences framing - telephoto lenses on the Olympus deliver more reach equivalent to a 2x focal length factor, useful for wildlife, but may feel limiting for wide landscapes unless you invest in ultra-wide lenses.

Autofocus Systems: Speed, Accuracy, and Tracking

Autofocus (AF) remains decisive for disciplines like sports, wildlife, and event photography requiring rapid and reliable subject acquisition.

The Olympus E-M1 impresses with an advanced hybrid AF system: 81 focus points blending phase-detection and contrast detection, eye detection for portraits, and continuous AF tracking - especially noteworthy for a 2013 camera. The AF points spread across much of the frame, giving flexibility in composition. Olympus also offers focus bracketing and stacking for macro enthusiasts, reflecting their attention to precision focusing.

The Sony A390, by contrast, employs a more basic 9-point phase detection AF, without cross-type sensitivity detailed. It lacks eye or animal detection modes, and continuous AF tracking is limited - ideal for static or slow-moving subjects rather than high-action scenarios. The Sony’s autofocus sometimes struggles in low contrast or dim lighting, a consequence of sensor/processing combination and dated AF tech in 2010.

In handheld street photography or casual portraits, Sony’s AF suffices, but for wildlife, sports, or fast events, Olympus’s superior AF will be evident.

LCD and Viewfinder Experience: What You See is What You Get

Both cameras offer tilting LCD screens enabling versatile shooting angles.

The Olympus E-M1’s 3-inch touchscreen with 1,037k dots outshines Sony’s 2.7-inch non-touch LCD with modest 230k resolution. This makes framing, menu navigation, and focus point selection more intuitive on the Olympus. For live view shooting or video, the clearer display is a boon.

On the viewfinder front, Olympus uses an electronic viewfinder (EVF) sporting 2.36 million dots with 100% coverage and 0.74x magnification - providing sharp preview, exposure simulation, and instant feedback on settings. Sony’s optical pentamirror OVF, while offering respectable 95% coverage and 0.49x magnification, lacks the useful exposure preview and can feel dimmer in low light.

For photographers transitioning from optical viewfinders, the Olympus’s EVF may take a moment to get used to but ultimately provides more information on the fly.

Lens Ecosystem and Compatibility

Olympus’s Micro Four Thirds mount boasts over 107 native lenses from Olympus, Panasonic, and third parties, ranging from ultra-wide primes to telephoto zooms with optical stabilization. The system is mature, affordable, and in addition, Olympus benefits from in-body image stabilization (IBIS), providing 5-axis correction.

Sony’s DSLR mount (Alpha/Minolta A-mount) has historically featured around 143 lenses, including classic Minolta glass, and some contemporary Sony models but fewer recent developments after Sony’s mirrorless focus shift. The A390 lacks IBIS; stabilization depends on lenses alone.

In practical use, Olympus’s IBIS and lens variety give photographers more creative flexibility, especially in low light or macro work. Sony users might lean on stabilized lenses or tripods.

Burst Rates and Video Capabilities: Capturing Movement

The Olympus signals pro ambitions with a 10fps burst rate - impressive for its class, helpful for sports and wildlife shooters trying to nail the decisive moment. In contrast, Sony’s 3fps drive speed is modest and more fitting for casual or posed photography.

Video has become integral for many users, and here Olympus provides full 1080p at 30fps video recording, ready for casual videography with decent H.264 compression and a mic input for basic audio capture. Sony’s A390 lacks video altogether, a significant omission by today’s standards but understandable given its 2010 release.

This makes the Olympus the better all-around multimedia performer, ready for hybrid shooters who toggle between stills and video.

Battery Life and Storage Flexibility

The Olympus E-M1 uses BLN-1 battery packs rated at roughly 350 shots per charge under CIPA standards, outperforming the Sony A390’s NP-FH50, which promises 230 shots - a 35% difference which we verified in mixed usage sessions.

Storage-wise, the Olympus accepts SDXC cards (up to very high capacities), while Sony supports both SD/SDHC and Memory Stick Pro Duo formats - a nice-to-have for those invested in Sony ecosystems but limiting in terms of universal compatibility.

Specialized Uses: Picking Cameras for Genres

To help pinpoint which camera fits your niche, I’ll walk through various photography disciplines examining both models’ suitability.

Portrait Photography: Skin Tones and Bokeh

Portrait artists prize accurate skin tone rendition, sharp eye detection autofocus, and the ability to isolate subjects with creamy bokeh.

The Olympus E-M1’s TruePIC VII processor alongside its 16MP CMOS Four Thirds sensor renders pleasing skin tones with rich color gradation and fewer artifacts in challenging light. The in-camera autofocus boasts eye detection, resulting in sharp portraiture with minimal hunting. However, the Four Thirds sensor’s smaller size results in a deeper depth of field at equal apertures compared to APS-C, making bokeh less pronounced unless very fast lenses are used.

Sony’s 14MP APS-C sensor, though CCD-based, produces somewhat neutral but less vibrant colors and less smooth bokeh due to fewer high-aperture lenses offered at entry level. Autofocus lacks eye detection, requiring more manual precision.

I lean towards Olympus for portrait work, especially for enthusiasts prioritizing autofocus reliability.

Landscape Photography: Resolution and Dynamic Range

Resolution is similar between cameras - Olympus at 16MP and Sony at 14MP. The E-M1’s higher dynamic range and greater bit depth make it more adept at holding detail in shadows and highlights - critical for sweeping landscapes with high contrast skies.

Weather sealing on Olympus allows shooting in demanding outdoor conditions, a distinct edge over the Sony's unsealed body.

Wildlife Photography: Autofocus and Telephoto Reach

Olympus’ 10fps burst mode, 81-point AF system, and 2x focal length multiplier all cater excellently to wildlife shooting. The 5-axis stabilization enables handheld telephoto shots with reduced shake.

Sony’s 1.5x APS-C crop provides less reach, and slower 3fps burst along with 9 AF points make it less suited for fast-moving subjects.

Sports Photography: Tracking and Frame Rates

Sports require fast autofocus and high burst rates. Olympus E-M1’s hybrid AF and doubled frame rate are clear advantages here. Sony A390 will struggle with sustained action.

Street and Travel Photography: Discreteness and Battery Life

Compact size, weather sealing, wireless connectivity, and a bright EVF make Olympus better for street and travel photographers. Battery life advantage widens in favor of Olympus, with 350 vs. 230 shots - noticeable on long trips.

Sony’s DSLR bulk and no weather resistance reduces comfort and reliability for roaming photographers.

Macro and Night/Astro Photography

Olympus supports focus bracketing and stacking, critical tools for macro photographers seeking greater depth of field. Its 5-axis IBIS further aids hand-held macro work in dim conditions.

Night and astrophotography demand excellent high ISO performance. Olympus’ superior DXO low-light ISO score (757 vs. Sony’s 607) and noise handling shine here, especially with sensor stabilization mitigating blur.
