Olympus E-PL3 vs Panasonic LX7 - An Expert Comparison for Photography Enthusiasts

When choosing a camera in the sub-$500 segment, curious photographers often find themselves torn between versatile, interchangeable-lens mirrorless systems and high-quality fixed-lens compacts. The Olympus PEN E-PL3 and the Panasonic Lumix DMC-LX7 fit squarely into these categories, each offering a distinct proposition. Over many hours of hands-on testing, lens swaps, and practical shooting scenarios, I've developed a deep understanding of their real-world strengths, technical nuances, and where each might fit in your photography kit.

Let me walk you through this detailed comparison, drawing from extensive experience with Micro Four Thirds systems, small sensor compacts, and their performance across major genres. Whether you're interested in portraits, landscapes, wildlife, or video, this guide aims to give you crystal-clear insight - and some images to boot - to help you decide.

First Impressions and Ergonomics: Size, Handling, and Control Layout

Let’s start by looking at the physical package - after all, how a camera feels in your hand shapes much of your day-to-day experience.

The Olympus E-PL3 adopts a rangefinder-style mirrorless body that feels markedly like a traditional camera despite its entry-level positioning. Measuring 110 x 64 x 37 mm and weighing 313 g, it is incredibly compact yet sporting a clean, minimalist aesthetic. The Olympus E-PL3's body invites customization with Micro Four Thirds lenses, giving you the freedom to adapt to many photo disciplines, from wide-angle landscapes to telephoto wildlife shots.

On the other hand, the Panasonic LX7 sports a solid, compact build with dimensions around 111 x 68 x 46 mm and a slightly lighter 298 g. Its all-in-one zoom lens eliminates the need for multiple lenses, making it an ideal grab-and-go device with modest bulk.

In my hands, the E-PL3's slightly sculpted grip offers more confidence for prolonged shooting sessions. The LX7, conversely, wins points for pocketability and convenience but may feel cramped if your hands are larger or you want the tactile feedback of physical controls for every adjustment.

Moving to control layout and top-panel design, both cameras provide essential dials and buttons but in very different arrangements.

The Olympus uses a more traditional mirrorless design, with dedicated dials for exposure compensation and a mode dial that feels reassuringly tactile. Button placement facilitates quick toggling between focus modes or metering types - a boon when shifting between portraits and street photography.

The LX7’s controls are somewhat more streamlined, reflecting its compact nature. The aperture ring on the lens barrel is a standout feature, giving quick manual aperture adjustments - a real treat for enthusiasts craving creative control while on the move. However, some buttons are smaller and less illuminated, which could hamper usability in low-light or fast-action scenarios.

Sensor Technology and Image Quality: Four Thirds vs 1/1.7” Sensor

No comparison is complete without looking under the hood - specifically, sensor technology.

The Olympus E-PL3 is powered by a 12MP Four Thirds CMOS sensor measuring 17.3 x 13 mm, significantly larger than the LX7’s 10MP 1/1.7” sensor (~7.44 x 5.58 mm). Larger sensors generally mean better noise performance, dynamic range, and depth of field control.

The E-PL3’s sensor area is roughly 225 mm², compared to LX7’s 41.5 mm² - over five times larger in area. This translates directly into the E-PL3’s superior color depth (20.9 bits vs 20.7 bits) and dynamic range (10.3 EV vs 11.7 EV – note here, the LX7 slightly leads in dynamic range, likely due to its sensor optimization and image processing). However, noise performance and ISO sensitivity favor Olympus, especially as ISO increases - the E-PL3 has a native ISO range of 200-12800 versus the LX7’s 80-6400 native ISO.

Practically, what does this mean? At base ISO, both cameras deliver remarkably clean images under good lighting; however, in shadows or dim environments, the E-PL3’s sensor shines with less chroma noise and more color fidelity. The LX7’s smaller sensor is surprisingly capable, especially considering its compact package, but noticeable noise creeps in above ISO 800.

Color responses between cameras are fairly neutral, although I noted the Olympus leans slightly warmer, which generally benefits skin tones in portrait photography.

Shooting Experience: Autofocus, Viewfinder, and Usability

While specs are important, how cameras perform AF-wise in real-world use is crucial.

The Olympus E-PL3 employs a contrast-detection AF system with 35 focus points, including face detection - though it lacks the newer phase-detect technologies. I found its autofocus to be commendably accurate for static subjects, with reasonable speed when hunting in live view. Continuous autofocus and tracking for moving subjects performed adequately but showed limitations on fast-moving wildlife or sports shots.

The LX7 offers 23 AF points, also relying on contrast detection and face detection. Its autofocus speed is notably quicker, especially in daylight, helped by a fast lens (F1.4-2.3) that aids in focusing speed and low-light AF robustness. Continuous AF tracking felt more responsive and snappier than the Olympus in burst mode scenarios.

Neither camera has built-in electronic viewfinders, though optional ones can be added, more common in Olympus systems. This is an important consideration if you often shoot under bright outdoor conditions where LCD visibility may suffer.

Speaking of LCDs:

The Olympus’s 3” tilting HyperCrystal LCD with a modest 460K resolution feels dated compared to the Panasonic’s fixed 3” TFT LCD with 920K resolution. For videographers and street shooters, the LX7’s brighter, sharper screen is a meaningful advantage for framing and reviewing shots on the go.

Image Samples and Real-World Output

Technical specs aside, image quality comes down to final output - and I’ve tested both cameras in diverse shooting environments.

Portraits: The Olympus E-PL3’s larger sensor and micro four thirds lens selection allow for more pronounced bokeh and better subject isolation. Skin tones appear more natural and less plasticky compared to the LX7. The LX7’s fast lens helps maintain sharpness on faces but the smaller sensor yields less background blur, making subject differentiation mild.

Landscapes: Both cameras capture respectable landscapes with good color accuracy, but Olympus edges ahead with sharper RAW files and more room to recover shadows due to higher dynamic range. The LX7’s built-in lens performs well across the zoom range, though diffraction softening is noticeable at the smallest apertures compared to prime or high-quality zooms on the E-PL3.

Wildlife: The Olympus has the advantage of interchangeable telephoto lenses, which opens creative possibilities beyond the LX7’s 24-90mm equivalent lens. AF speed and tracking on E-PL3 lag somewhat, but higher resolution images and longer focal length options favor it for serious wildlife photography. The LX7’s fast burst mode (11 fps) can help when timing is critical but cropped images from zoom fall short in quality.

Sports: Sports shooting demands fast AF and high frames per second shooting - here, Panasonic’s LX7 wins with 11 fps burst versus Olympus's 6 fps. However, autofocus tracking still lags behind modern cameras. Low light shooting at sports events is challenging for both but mounts with fast primes on the E-PL3 give a better edge.

Street Photography: The LX7’s pocketable size, quick AF, and bright lens make it a stealthy choice for street shooters craving discretion. The Olympus, while compact, requires lens changes and is less discreet. The LX7’s sharp wide-angle and ability to tap into faster shutter speeds helps freeze spontaneous moments.

Macro Photography: Olympus excels with macro-capable lenses offering precise manual focus and impressive magnifications. The LX7’s minimum focus distance at 1cm is surprisingly versatile but manual focus adjustments are less tactile.

Night and Astro Photography: Both cameras struggle somewhat at very high ISO; Olympus’s better noise control gives it the edge. Lack of built-in intervalometer on the E-PL3 hurts timed exposure astrophotography, while LX7’s time-lapse recording built-in is a handy bonus.

Video Capabilities: Which Camera Handles Motion Better?

Video shooters will appreciate the subtle differences here.

The Olympus E-PL3 records Full HD 1080p at 60fps (AVCHD and MJPEG), but image stabilization is sensor-based and can struggle with significant motion. Audio inputs are limited (no mic or headphone ports), restricting audio control for pros.

The Panasonic LX7 matches 1080p at up to 60fps but benefits from optical image stabilization - generally smoother results handheld. It supports both AVCHD and MPEG-4 formats, with time-lapse features adding creative options. Like Olympus, it lacks external microphone support.

Between the two, I found the LX7’s video slightly more pleasant for run-and-gun shooting due to its lens stabilization and sharper LCD.

Lens Ecosystem and Expandability

One of Olympus E-PL3’s winning features is access to over 100 Micro Four Thirds lenses, unlocking broad creative horizons. From ultra-wide to super-telephoto to specialized macro primes, the system caters to virtually every photography niche.

The Panasonic LX7, being a fixed-lens compact, lacks this modularity but compensates with a versatile built-in zoom spanning wide-angle 24mm to medium 90mm equivalents, with a very bright F1.4 aperture at the wide end.

For enthusiasts valuing flexibility and future-proofing, the Olympus’s lens mount is a strong argument.

Build Quality, Weather Sealing, and Battery Life

Neither model boasts professional-grade weather sealing; both are vulnerable to dust and moisture, necessitating care when shooting outdoors in challenging conditions.

The Olympus’s metal construction feels robust yet lightweight, suitable for extended handheld use; the LX7 feels sturdy but meant for casual carry rather than heavy-duty use.

Battery life favors the LX7 slightly (~330 shots per charge vs 300 shots in Olympus), though real-world use, especially with LCD tilt and live view, can influence endurance.

Connectivity and Storage

Both cameras rely on SD/SDHC/SDXC cards for storage, standard fare.

Connectivity is basic: USB 2.0 and mini HDMI ports serve data transfer and external display needs. Neither camera offers built-in Wi-Fi, Bluetooth, or GPS, which is understandable given their vintage but may frustrate modern workflows that favor wireless transfer options.
