In the dynamic world of mirrorless cameras, Micro Four Thirds (MFT) models continue to balance compact design, versatile lens options, and capable performance - ideal for enthusiasts and professionals alike seeking a blend of portability and image quality. Today, I dive deep into a side-by-side comparison of two distinct MFT contenders launched within the last few years: the Olympus PEN E-P7 and the Panasonic Lumix DC-GX9.

Both cameras address different segments of the market yet share many sensor-related specs and a similar form factor. Having spent extensive hours shooting with each across multiple genres including portraiture, wildlife, landscape, and video, I’m eager to share nuanced insights on their practical performance, strengths, and trade-offs. This comparison will guide you in selecting the model best tailored to your photographic ambitions and style.

The Battle of Body Design and Ergonomics: Tiny but Mighty

For many photographers, the tactile feel and handling experience strongly shapes a camera’s enjoyment. The Olympus E-P7 epitomizes the classic rangefinder-style mirrorless body with a clean, minimalistic aesthetic that Olympus has championed for years. Its dimensions are 118 x 69 x 38 mm, weighing an impressively light 337 grams - encouraging handheld shooting and prolonged use without fatigue.

In contrast, the Panasonic GX9, launched earlier in 2018, is marginally larger and heavier at 124 x 72 x 47 mm and 407 grams. The extra heft translates into a subtly more robust grip, which may comfort photographers with larger hands or those favoring stability over pocketability.

The tilting touchscreen on both cameras measures 3 inches, yet I noticed the E-P7’s touchscreen is exceptionally responsive and user-friendly, particularly for quick selfie compositions (it’s “selfie-friendly” as Olympus explicitly highlights). The GX9's screen boasts a slightly higher resolution at 1240k dots versus 1040k dots on the E-P7, offering a crisper viewing experience - though the difference is subtle in everyday use.

Below, the top-view layout reveals a difference in button placement and control dials that speak to the cameras’ intended user-base.

The GX9 carries forward Panasonic’s more intricate control scheme, appealing to photographers who prefer direct access to multiple settings without diving into menus. Olympus’s E-P7 simplifies the controls, leaning toward a novice or enthusiast audience favoring ease of use and intuitive navigation.

Bottom line: If you prize feather-light build, sleek portability, and a friendly touchscreen interface, Olympus E-P7 takes the ergonomic edge. For photographers who want more physical control dials and a firmer grip to anchor advanced shooting, the Panasonic GX9 is compelling.

Sensor Specs and Image Quality: Nearly Identical, but Subtle Differences Matter

At the heart of both cameras lies a 20-megapixel Four Thirds CMOS sensor without a low-pass (anti-aliasing) filter - a technical feature typically enhancing detail resolution and sharpness.

From a purely sensor standpoint, both deliver an effective resolution of 5184 x 3888 pixels, with native ISO ranges from 200 to 25600. The slight difference in sensor area - 226.20 mm² for Olympus and 224.90 mm² for Panasonic - is practically negligible.

But, as someone who’s run extensive side-by-side RAW file shoots and ISO performance tests, I’ve found:

• Color reproduction: Olympus showcases a slightly warmer and more natural skin tone rendition, lending itself better to portrait and street photographers aiming for pleasing skin aesthetics straight out of camera.
• Dynamic range: The Panasonic GX9 has a slighter advantage in shadow recovery and highlights retention - granted, not enough to overshadow Olympus’s credible performance but noticeable in very contrasty landscapes.
• Low light: Both cameras handle high ISO reasonably well for MFT standards; the GX9 edges just ahead with less noise at ISO 3200 and above, likely benefitting from its Venus Engine processor's noise reduction algorithms.

The absence of a dedicated electronic viewfinder (EVF) on the Olympus E-P7 is an important image-preview limitation for some. The GX9’s built-in EVF has a high-resolution 2760k-dot panel with 0.7x magnification, facilitating precise framing even in intense sunlight or low-light conditions.

User Interface and Display: Touch, Tilt, and Viewfinder Experience

While both cameras feature tilting, touch-enabled LCD screens, their user interface philosophies diverge.

Olympus’s UI is sleek, minimalist, and easy to navigate, guided by large icons and streamlined menus that cater to newer users or those who want quick access without a steep learning curve. I especially appreciated the fun “selfie mode” app integration, making it a great companion for casual and social shooters.

Panasonic’s GX9 interface, on the other hand, offers finer granular control - including customizable function buttons and more comprehensive in-camera image editing tools. Yet, this complexity may feel overwhelming for beginners initially.

Crucially, the GX9’s EVF provides an experience closer to traditional DSLR shooting, allowing for eye-level operation and enhanced composition reliability - something the E-P7’s absence of an EVF inherently lacks.

Autofocus Systems: Speed, Accuracy, and Subject Tracking

Autofocus (AF) performance is a pivotal factor across photography genres, especially fast-paced environments like sports or wildlife.

• Olympus E-P7’s AF system uses 121 contrast-detection points with face/eye detection enabled. While contrast detection is traditionally slower, Olympus’s proprietary algorithms make it surprisingly snappy for portraits and street photography, especially indoors where lighting is controlled.
• Panasonic GX9 employs 49 focus points but combines both contrast and phase-detection AF for improved speed and tracking accuracy. This hybrid AF approach gives GX9 the edge in continuous autofocus scenarios, especially capturing moving subjects in daylight.

In real-world testing, the GX9 maintains better subject lock in burst mode – it captures 9 frames per second versus the E-P7’s 8.7 fps, a marginal yet meaningful distinction when shooting fast action.

Neither camera includes advanced animal eye autofocus, which is a downside for serious wildlife photographers wanting pinpoint animal subject tracking.

Handling Across Photography Genres

Let’s break down how each camera performs in real shooting contexts, from portraits to astrophotography.

Portrait Photography: Rendering Skin and Capturing Eyes

Olympus E-P7, with its warmer color science, excels in portraiture. The face and eye detection is highly reliable, enabling you to capture sharp portraits with pleasing skin tones straight from the JPEG engine. Combined with the extensive Micro Four Thirds lens lineup of 118 options boasting dreamy fast primes, the E-P7 becomes a compelling travel or street portrait companion.

That said, the lack of an EVF means holding the screen longer for framing, which can be awkward in bright sunlight or when needing subtle focus adjustments.

The GX9’s EVF enhances precision framing and the Venus Engine processes skin tones slightly cooler but very natural. Its hybrid AF locks nicely on eyes, useful when working with fast-moving subjects or outdoors.

Landscape Photography: Resolution, DR, and Weather Resistance

Neither camera offers weather sealing, a limitation in unpredictable conditions. However, their compactness and tilt screens are beneficial for landscape composition from low or high angles.

With near-identical sensor resolution and image quality, Panasonic’s slight edge in dynamic range aids in capturing scenes with challenging exposure contrasts - like sunrise over mountains.

Long exposure and timelapse functions on both cameras perform solidly, but Olympus’s wider native lens choices include some ultra-wide primes that landscape shooters will appreciate.

Wildlife and Sports Photography: AF Speed and Burst

If your interest lies in shooting action, the Panasonic GX9 is better suited for wildlife and sports photography. The hybrid AF system with phase detection faster and more reliable in tracking erratic movement. Its 9 fps burst further supports capturing peak action moments.

The Olympus E-P7’s slower contrast-detection autofocus and slightly lower burst speed make it less optimal for these realms, though not unusable for casual use or slower subjects.

Street and Travel Photography: Discretion and Portability

Both cameras are compact, but Olympus E-P7’s diminutive weight and size give it an advantage when discretion and all-day carry comfort matter. The ability to flip the screen for selfies or varied framing angles caters nicely to street shooters and social photographers.

The Panasonic GX9’s focus bracketing and stacking support, as well as post-focus modes, afford creative macro work beyond the Olympian E-P7’s more limited macro functionality.

For night or astrophotography, both cameras perform respectably at high ISO, with the GX9’s superior sensor processing slightly reducing noise at the upper ISO ranges. Neither offers specialized exposure modes for astro, so manual control remains essential.

Video Performance: Capabilities and Limitations

Video shooters will find both cameras capable of 4K UHD recording at 30p and lower frame rates with solid bitrates (Olympus at 102 Mbps; Panasonic varies).

However, neither includes microphone or headphone jacks, limiting audio capture options for professionals. Both offer in-body 5-axis image stabilization, effectively smoothing handheld video.

The Panasonic GX9 additionally supports 4K photo mode, enabling extraction of 8MP stills from 4K video, a feature the E-P7 lacks.

While both cameras handle basic video needs well, like vlogging or casual filmmaking, pros demanding external audio inputs or advanced recording formats might look elsewhere.

Professional Use and Workflow Integration

In professional contexts, reliability, file format support, and workflow integration are key.

Both Olympus and Panasonic support RAW shooting with 20MP resolution, offering ample latitude in post-production. Olympus’s RAW files tend to be slightly larger due to its processing but preserve subtle tonal gradations that advanced retouchers may appreciate.

Build materials on both cameras lack full environmental sealing, so cautious handling is advised in challenging conditions.

In terms of connectivity, both incorporate built-in Wi-Fi and Bluetooth for seamless image transfer and remote control via smartphone apps, although Panasonic’s Venus Engine sometimes achieves faster file transfer speeds.

Single SD card slots on both cameras limit professional adaptability; no dual card backup offerings here.
