Panasonic G5 vs Sony NEX-5

Panasonic Lumix G5 vs Sony Alpha NEX-5: A Hands-On Comparison of Two Entry-Level Mirrorless Titans

Stepping into the mirrorless camera arena during the early 2010s was a journey of bold innovation, and two trailblazers - the Panasonic Lumix DMC-G5 and the Sony Alpha NEX-5 - quickly carved their niches among enthusiasts eager to get mirrorless benefits without a premium price tag. The Lumix G5 made its debut in mid-2012, positioned as a successor to Panasonic's G3 offering a blend of robust usability and sharp imaging. Meanwhile, Sony's NEX-5, launched two years earlier in 2010, pioneered the compact rangefinder-style mirrorless approach with a focus on image quality and portability.

Having spent countless hours running these cameras through various genres and side-by-side tests, I’m excited to share a detailed comparison that goes beyond specs and marketing speak. We’ll dig into sensor technology, autofocus performance, ergonomics, and real-world photography scenarios to help you understand which camera best fits your style and expectations.

First Impressions and Build: User Feel Meets Design Philosophy

When you first hold the Panasonic G5 and Sony NEX-5, you immediately sense two different design philosophies. The G5 embraces a traditional SLR-style mirrorless body, which Panasonic clearly intended to appeal to shooters craving a comfortable grip and tactile controls familiar to DSLR users. Its dimensions (120x83x71 mm) and weight (396g) reflect a moderately chunky but well-balanced camera, with a solid grip that encourages longer handheld shooting sessions.

In contrast, the Sony NEX-5 flirts with rangefinder minimalism, sporting a notably more compact and light body - 111x59x38 mm at just 287g. This makes it a marvel to carry around, especially for street photographers and travelers prioritizing discreteness and weight savings. However, that slim design comes at a cost: reduced ergonomics for those with larger hands and fewer physical controls, which we will touch on soon.

The difference in body footprint and comfort is well illustrated here:

Panasonic’s approach here lends itself to photographers who want more dials and buttons within reach while shooting. Meanwhile, Sony takes a minimalist route, with fewer buttons and more reliance on menus, which some users might find less intuitive.

For entry-level mirrorless cameras, build quality for both is decent but not weather-sealed or ruggedized. Neither manufacturer claimed environmental sealing, so care in rough conditions is advised.

Sensor Technology and Image Quality: The Heart of the Matter

Under the hood, the choice of sensor technology sets these cameras apart meaningfully. The Panasonic G5 houses a Four Thirds sensor measuring 17.3x13 mm with a resolution of 16MP. The Sony NEX-5 sports an APS-C sensor, larger at 23.4x15.6 mm, but a slightly lower 14MP resolution. This discrepancy is an important one - sensor size directly affects noise performance, dynamic range, and depth of field control.

In controlled tests, the Sony’s larger APS-C sensor impresses with greater color depth (22.2 bits vs Panasonic’s 21.4), improved dynamic range (12.2 EV vs 11.6 EV), and better low-light performance (ISO 796 vs 618 ISO DXO scores). While the 16MP of the G5 offers higher pixel count potentially advantageous for crops, the quality per pixel favors the NEX-5 in my evaluations.

The difference in sensor sizes impacts field of view too. Panasonic's Micro Four Thirds system applies a 2.1x crop factor, restricting your effective focal length range, whereas Sony’s APS-C sensor with a 1.5x crop factor provides a wider angle of view from the same lens focal length.

This helps explain the varying results in landscapes and portraits, which we’ll explore shortly.

Visually, here’s how these sensor areas stack:

Handling and Controls: Where Ergonomics Shape the Experience

Experience in the field is influenced heavily by how intuitively controls feel. Panasonic G5 benefits from its SLR-like control scheme: dedicated dials for aperture, shutter speed, and exposure compensation are a photographer’s dream for seamless manual adjustments. The rear’s fully articulating touchscreen (3”, 920k dots) further empowers framing from unusual angles, perfect for macro or creative video work.

Sony’s NEX-5 takes a straighter, simpler path. It lacks an electronic viewfinder (EVF), relying on its rear tilting screen to compose shots - a disappointment for many who prefer eye-level shooting for better stability. The 3" 920k LCD screen is tiltable but not fully articulating nor touchscreen-enabled, which limits flexibility somewhat. Physical controls are sparse, requiring more menu navigation than some enthusiasts prefer.

Here’s a direct comparison of both rear layouts and displays:

In low light or action situations, Panasonic's EVF is a significant advantage, providing more precise framing and feedback than Sony’s purely LCD-dependent system. Both cameras lack any form of in-body stabilization - naturally shaking hands or longer focal lengths will benefit from optically stabilized lenses if available.

Autofocus Systems: Tracking and Precision in Diverse Scenarios

Autofocus (AF) remains a crucial usability pillar, especially in genres like wildlife, sports, and street photography where unpredictability is abundant.

The Panasonic G5 employs a contrast-detection AF system with 23 focus points and face detection enabled. Although contrast-detect is inherently slower than phase-detect, the G5’s AF speed is respectable within its price tier and excels with static subjects and controlled lighting. Continuous AF tracking works reasonably well but struggles with fast-moving subjects.

Sony’s NEX-5 also uses contrast-detection with 25 AF points but lacks face or eye-detection features. In practical tests, the NEX-5’s AF tended to be slightly faster in good lighting, helped by a leaner sensor readout and processor efficiency. However, continuous autofocus tracking suffers in challenging motion or dim environments, occasionally hunting excessively.

Neither supports advanced phase-detect AF or animal eye AF, which limits these models for modern wildlife or sports enthusiasts. For macro work, Panasonic’s touchscreen focusing aids precision, although both cameras offer manual focus options.

Image Stabilization, Burst Rates, and Shutter Characteristics

A notable omission from both cameras is in-body image stabilization (IBIS). Panasonic and Sony depend on optical stabilization built into certain lenses if available - users of legacy or prime lenses without stabilization must brace for increased camera shake.

Regarding burst shooting, the Sony NEX-5 outpaces the Panasonic G5 slightly, offering 7 frames per second versus 6 fps on the G5. In practice, this difference is marginal and rarely decisive unless you frequently shoot fast-moving action like sports or birds in flight.

The G5’s shutter speed ranges from 60 seconds to 1/4000 seconds, while the NEX-5 offers 30 seconds to 1/4000 seconds. Both perform equivalently here, with no silent or electronic shutter variants available, which can be limiting in some discrete shooting scenarios.

Video Capabilities: Cinema-Ready or Casual Filming?

Let’s shift gears into motion where both cameras offer solid but dated video capabilities for their time.

Panasonic leverages the Venus Engine VII FHD processor to deliver Full HD 1080p video at up to 60fps, along with 720p and standard-definition options. The articulating touchscreen simplifies framing when recording, and a built-in flash is also something of a novelty for video in this category.

Sony’s NEX-5 equally supports 1080p at 60fps but also includes a 1440x1080 (30fps) mode, which is not HD but was a useful legacy option during early HD video adoption. The absence of a microphone input on both models is a missed opportunity for video enthusiasts wanting enhanced audio control. Neither camera features 4K video or high-bitrate professional codecs, so expect basic but respectable HD video quality, fine for casual vlogging or family moments.

Photography Disciplines: How Do They Perform in the Field?

Portrait Photography
Panasonic’s face detection autofocus and articulating touchscreen assist in achieving tack-sharp portraits. Its Four Thirds sensor does limit shallow depth of field compared to Sony’s APS-C, making bokeh slightly less creamy but manageable with fast lenses. Skin tone reproduction on the G5 leans toward warmth and pleasing naturalness. The NEX-5, with larger sensors and higher dynamic range, provides slightly better subject-background separation, though the absence of face detection autofocus means more reliance on manual finesse.

Landscape Photography
Sony's APS-C sensor edges out with superior dynamic range and low noise at base ISO - critical for those grand vistas where highlight retention and shadow detail matter deeply. Panasonic does stiffly compete here but cannot match the latitude of the NEX-5 sensor, especially in challenging lighting. Both support multiple aspect ratios, but the G5’s higher pixel count gives a bit of room for cropping flexibility.

Wildlife and Sports
Neither camera is a dedicated speed demon, though Sony’s marginally faster burst rate and AF make it the better option in quick-action shooting. The G5’s superior handling and EVF allow more predictable framing, but autofocus tracking limitations hinder success with erratic subjects. Both lack lens choices tailored toward long super-telephotos in their native kits.

Street Photography
Here Sony shines with sheer portability and low profile. The NEX-5 is stealthier for candid moments, especially with pancake lenses. Panasonic's larger body is less discreet but benefits from an EVF for eye-level shooting, which can help maintain composition amid urban chaos.

Macro Photography
Panasonic's fully articulating touchscreen and tactile controls edge ahead in close focusing precision. Lens ecosystem is robust on Micro Four Thirds for macro-centric optics, often with optical stabilization absent in Sony’s E-mount primes of that era.

Night and Astro Photography
Sony’s lower noise at high ISO and dynamic range advantage is critical under starry skies or cityscapes. The NEX-5’s sensor handles ISO 1600+ cleaner and captures subtle details better. Panasonic’s camera will still do the job, but with more noise and less highlight retention.

Travel Photography
A classic debate - Panasonic offers better grip, controls, and a viewfinder for varied shooting situations, beneficial on longer outings. Sony brings remarkable compactness weighing nearly 30% less, favoring travelers prioritizing pack weight or needing a small camera for urban exploration.

Lens Ecosystem and Compatibility

Micro Four Thirds, championed by Panasonic, boasts a vast lens selection from Panasonic, Olympus, Sigma, and third parties, covering almost every photographic genre at affordable price points. With 107 lenses available at the time, the system favors photographers wanting versatility.

Sony’s E-mount lens lineup was younger and smaller in 2010-2012 but grew rapidly alongside NEX evolution. The NEX-5 benefits from 121 lenses on offer, including prime, zoom, and specialty optics. However, early-adopter lenses tended toward primes and compact zooms, with fewer specialized wildlife or macro options available than Micro Four Thirds.

Lens autofocus performance and optical stabilization depend heavily on the lens choice in both systems due to lack of in-body stabilization.

Connectivity, Battery Life, and Storage: Practical Matters

Neither camera offers wireless connectivity (Wi-Fi, NFC, or Bluetooth), which was typical of entry-level mirrorless of their generation. HDMI and USB 2.0 ports are present, enabling tethering and video output, though slow USB affects file transfer rates.

Battery life is surprisingly comparable: Panasonic’s G5 rates around 320 shots per charge, Sony’s NEX-5 about 330 shots. In my experience, actual real-world shooting (including LCD use and video) reduces these figures slightly. Spare batteries are advised for extended shoots.

Storage is standard SD/SDHC/SDXC for Panasonic and SD plus Memory Stick support for Sony - a consideration if already invested in Sony’s proprietary cards or accessories.

Price-to-Performance and Who Each Camera Best Serves

Pricing around launch had Panasonic G5 at approximately $699 and Sony NEX-5 closer to $599 - a modest difference considering feature sets. Fast-forwarding years later, both cameras are relatively affordable on the used market, appealing to budget-conscious hobbyists or those wanting an introduction to interchangeable lens mirrorless.
