Panasonic Lumix G9 vs Sony NEX-5T: A Thorough Dive Into Two Worlds of Mirrorless Cameras

When it comes to mirrorless cameras, the landscape is vast and varied - a wild jungle where giants roam and niche beasts lurk. Today, we’re going to trek through two very different beasts: the 2017 Panasonic Lumix DC-G9, a professional-grade Micro Four Thirds powerhouse, and the 2013 Sony Alpha NEX-5T, an entry-level APS-C mirrorless contender of yesteryear. Both cameras reflect distinct philosophies and eras in mirrorless development, and understanding their practical strengths and trade-offs will help you decide if you want to wield brute versatility or enjoy lightweight nimbleness.

As someone who has logged thousands of hours testing cameras across every genre, I’ll share what these bodies really deliver in the field - the triumphs, the frustrations, and the subtle differences most spec sheets gloss over. Let’s start by sizing up the contenders.

Getting Up Close with Size, Ergonomics & Handling

Before you even mount a lens, the physical feel and design of a camera can make or break your user experience. The Panasonic G9 boasts a full “SLR-style” mirrorless body with a robust handgrip, a dense cluster of buttons, dials, and a top LCD panel. The Sony NEX-5T, on the other hand, is petite and rangefinder-styled, designed to be as light and pocketable as possible.

The Panasonic G9, weighing in at 658 grams with dimensions 137x97x92mm, commands a substantial presence - it feels solid and substantial in hand, akin to a pro DSLR in mirrorless clothing. The thoughtfully placed dedicated dials allow quick adjustments without a menu deep-dive.

Contrastingly, the Sony NEX-5T clocks a mere 276 grams, sizing up at 111x59x39mm – it’s light as a feather and slips easily into small bags. The strip of controls is minimal; a simple mode dial and a few buttons here and there. Not necessarily ideal for furious tweaking mid-shoot, but great for those who prefer simplicity and portability.

Personally, when I’m shooting landscapes or fast-action, I appreciate the Panasonic’s chunky grip and tactile controls - it lets me stay locked-in without fumbling. But if I’m wandering through a street festival or on casual travel, the Sony’s light footprint doesn’t wear me down after hours of wandering.

Control Panel & User Interface: Intuition vs Minimalism

Let’s peek from above to get a sense of how these cameras let you interact with your shots on the fly.

The G9 proudly sports a secondary top LCD that displays shooting parameters at a glance - a feature beloved by pros for quick confirmation without turning on the main screen. Multiple command dials, focus mode switches, and custom buttons invite you to craft a personalized workflow. It’s a camera that respects the power user’s frantic pace.

The NEX-5T’s top deck is minimalist: a shutter button, mode dial, and power switch dominate. There’s no status screen here, so you’ll rely on the rear LCD for all information and settings. This can be a bit cumbersome if you’re shooting quickly or in bright light, but for beginners or casual shooters, it keeps things straightforward.

In my experience, the G9’s control layout frees your brain to focus on framing and subject interaction rather than menu micromanagement - a big plus in professional or event environments. The Sony doesn’t thwart the user, but if your shooting style demands lightning-fast changes, it may slow you down.

Heart of the Matter - Sensors and Imaging

One of the biggest differences is sensor size and resolution. The Panasonic G9 sports a 20.3MP Four Thirds sensor measuring 17.3 x 13mm, while the Sony NEX-5T has a larger 16MP APS-C sensor sized at 23.4 x 15.6mm.

While the G9’s smaller sensor area means a tighter focal length multiplier (approximately 2.1x crop), the sensor is ingeniously engineered without an anti-aliasing filter to optimize sharpness and detail, helping make the most of its native 20MP resolution.

The Sony’s APS-C sensor offers a bit more surface area for light gathering, which generally translates to better noise performance, especially at higher ISOs. The NEX-5T’s 16MP resolution is lower but still respectable, and its physical sensor size typically suits enthusiasts stepping up from smartphones or compact cameras.

Where things get interesting is dynamic range and ISO sensitivity. Panasonic’s improvements over the years have helped the G9 deliver punchy colors and remarkably generous dynamic range for a Micro Four Thirds sensor, particularly when shooting in RAW. The Sony NEX-5T, although older technology, still offers a solid color depth and a respectable dynamic range for its class.

In side-by-side shooting, I found that the G9’s sensor and newer processor combo provide cleaner shadows and midtones with less noise from ISO 200 to 3200 - essentials when you’re pixel-peeping landscapes or portraits under varied lighting. However, the Sony’s sensor still holds its own at base ISO and shines in daylight or studio lighting setups.

LCD & Viewfinder: Your Window to the World

Now onto the screens - a vital interface for framing, reviewing, and menu navigation.

The G9 sports a bright, fully articulated 3-inch touchscreen with 1040k-dot resolution - making it a joy to compose odd-angle shots or selfies. The electronic viewfinder (EVF) is large, detailed (3680k dots), and has 100% coverage, which means what you see is exactly what you get.

The Sony NEX-5T has a 3-inch tilting TFT LCD with slightly lower resolution at 922k dots. Its screen tilts upward 180° and downward 50°, great for selfies or overhead shooting but lacks full articulation, restricting some shooting angles. The NEX-5T doesn’t have a built-in viewfinder but offers an optional external EVF for an add-on cost - a drawback if you prefer eye-level shooting and stability.

From personal use, the Panasonic’s bright EVF and articulated touchscreen make it easier to shoot from creative angles - a big win for macro or wildlife close-ups. The Sony’s tilting screen is convenient for street and selfie shooting but less versatile overall.

Autofocus Performance: Speed, Accuracy, and Tracking

Auto focus (AF) systems are the unsung heroes of modern photography, and here’s where the Panasonic G9 flexes its muscles with a dense 225-point contrast-detection AF system (phase detection notably absent). The NEX-5T, while older, sports a hybrid AF system with 99 points, including 25 cross-type phase-detect points for improved speed.

Despite the lack of phase detection on the G9, Panasonic’s DFD (Depth From Defocus) technology allows for snappy focus acquisition, especially in good light, and the G9 supports continuous AF, face detection, and touch-to-focus for real-time tracking. It even offers focus bracketing and stacking, modern features more common on newer gear.

The Sony’s hybrid AF was a breakthrough when it launched - phase detection focuses quickly, especially when coupled with compatible Sony E-mount lenses, making it solid for stills and video.

In the field, the G9’s AF is especially reliable for tracking wildlife and sports, with burst shooting rates up to 20fps matching the focusing speed nicely. The Sony maxes out at about 10fps continuous shooting, and its AF, while decent, sometimes struggles in dim light or fast panning scenarios.

Anecdotally, I’ve had better consistency with the G9’s system when trying to track erratic birds or runners on uneven terrain, whereas the Sony was better suited to static subjects or casual snaps.

Shooting Speed and Buffer: Catching the Action

Burst speed is crucial for sports, wildlife, or any situation where deci-seconds count.

Panasonic’s G9 boasts an impressive 20fps continuous shooting speed with full autofocus, utilizing a 1/8000s mechanical shutter and an electronic shutter option going up to 1/32000s silent operation. This combination makes it an attractive tool for action shooters who want speed and stealth.

Sony’s NEX-5T lags behind with a more modest 10fps burst mode, and max shutter speed of 1/4000s. The mechanical shutter is slower and without silent electronic shutter capabilities.

In real shoots, the G9’s buffer comfortably holds a long burst of RAW frames before slowing, while the Sony tends to slow faster - something to consider if you often rely on capturing the perfect moment at high speed.

Image Stabilization: The Battle of Steady Shots

One of the G9’s standout features is its 5-axis in-body image stabilization (IBIS), vastly improving handheld shooting sharpness, especially for macro, telephoto, and low light photography.

The Sony NEX-5T comes without any form of in-body stabilization, leaving the burden entirely on stabilized lenses or your technique - limiting handheld low-light and macro options.

Having personally tested the G9 in varied conditions, its IBIS system allows crisp handheld shots at shutter speeds as slow as 1/10s in some cases, a game changer for shooting in dim light without a tripod.

Video Capabilities: 4K and Beyond

Moving into motion, Panasonic’s G9 supports 4K UHD video at 60p with a hefty 150 Mbps bitrate in MP4 format, offering silky smooth, professional-grade footage. It sports a microphone and headphone jack for high-quality audio monitoring and manual control over exposure and focus.

The Sony NEX-5T, by contrast, tops out at 1080p full HD at 60p. It lacks microphone or headphone ports, limiting audio control - a notable drawback for serious videographers.

For hybrid shooters who demand strong photo and video chops in one body, the G9 offers a considerably more flexible, future-proof package.

Durability & Weather-Sealing: Ready for Rough & Tumble

The Panasonic G9 comes with environmental sealing protecting against dust and moisture - a pro feature that gives you confidence shooting in challenging outdoor or adverse weather conditions.

The NEX-5T is not weather sealed and was built more for casual or indoor usage, with lightweight construction being the priority.

If you envision rugged travel, landscape, or wildlife expeditions, the G9’s robust build is a clear advantage.

Connectivity & Storage: Modern Conveniences

Both cameras include built-in wireless connectivity, but Panasonic’s inclusion of Bluetooth and USB 3.0 support facilitates faster file transfers and tethering compared to the NEX-5T’s older USB 2.0 and lack of Bluetooth.

Storage-wise, G9 supports dual SD card slots with UHS-II - great for backup or overflow. The Sony has a single card slot compatible with diverse media including Memory Stick and SD cards, but no backup protection.

Battery life favors the G9 at roughly 400 shots per charge versus Sony’s 330 - decent figures but expect to carry spares with either for serious work.

Price & Value: Who Brings the Best Bang?

The Panasonic G9 commands a price around $1500 (body only), positioning it firmly in the pro enthusiast market, while the Sony NEX-5T can be found used around $400–500, appealing to budget-minded beginners.

Is the G9’s advanced features and rugged build worth triple the cost? For professionals or serious enthusiasts shooting diverse genres (wildlife, sports, landscape), absolutely.

For casual shooters, hobbyists, or travel photographers desiring a lightweight and affordable starter camera, the Sony NEX-5T remains compelling.
