Panasonic GM5 vs Samsung NX10: A Hands-On Mirrorless Camera Comparison for the Discerning Photographer

Choosing between the Panasonic Lumix GM5 and the Samsung NX10 might feel like stepping into a time machine. Both are entry-level mirrorless cameras introduced in the early 2010s, yet they uphold rather different design philosophies and technological choices. Having tested both extensively over the years - through portrait shoots, wildlife adventures, and even astrophotography sessions - I’m ready to dissect the nuances that separate these two cameras. Whether you’re a seasoned enthusiast or a professional seeking a supplemental tool, this comparison will help you understand how each performs across disciplines, and where each shines or stumbles.

Let’s begin the exploration.

Size, Handling, and Ergonomics: Tiny Gem Meets Tried-and-True SLR Form

The Panasonic GM5 is a compact rangefinder-style mirrorless, while the Samsung NX10 follows a bulkier SLR-style layout. What’s the real-world impact of these form factors? I often say handling can make or break the shooting experience, so let’s inspect closely.

At just 99x60x36mm and weighing a featherlight 211 grams, the GM5 is a marvel of miniaturization. It easily slips into jackets or even coat pockets. However, its diminutive size means some compromises: the grip is minimal, and if you have larger hands (or prefer a firm grasp), the handling can feel precarious during prolonged use.

In contrast, the NX10 is roughly twice the weight at 499 grams and measures 123x87x40mm, leaning into a more traditional DSLR-inspired shape. This affords a robust handhold and a satisfying tactile feeling, especially when attaching longer lenses. If you prefer a camera that feels substantial without being a burden, the NX10's body is compelling.

The control layout also reflects these differences. Check out the top panel comparison:

The GM5 sports an elegant but minimalist control scheme, with fewer dedicated dials and buttons - likely to maintain its svelte form. It’ll suit shooters who prefer menu-driven operations or touchscreen interactions. On the flip side, the NX10 includes more physical dials and buttons, giving quicker manual access, which I appreciate for dynamic shooting conditions like sports or wildlife.

In short: if portability and discrete travel photography rank high for you, the GM5’s size is a dealmaker. For more tactile engagement and traditional ergonomics, NX10 wins.

Sensor and Image Quality: Micro Four Thirds vs APS-C – The Pixel Battle

Sensor technology often dictates a camera’s image-making potential. The Panasonic GM5 uses a Four Thirds CMOS sensor measuring 17.3x13mm, whereas the Samsung NX10 features a larger APS-C CMOS sensor at 23.4x15.6mm.

The sensor size difference translates into the Panasonic having a 2.1x crop factor, and the Samsung approximately 1.5x. Larger sensors generally mean better image quality, especially in low light, due to bigger pixels capturing more light.

Assessing lab data, the Panasonic GM5 scored an overall DXOmark sensor rating of 66 points, compared with the NX10’s 63. That’s a closer contest than one might expect. The GM5 excels with a slightly higher dynamic range of 11.7 stops compared to the NX10’s 10.8 stops, beneficial for preserving details in highlights and shadows.

However, color depth favors the NX10 marginally (22.8 bits vs 22.1 bits), hinting at subtler color gradations. The GM5 also boasts a higher max ISO of 25600, though practical usability tapers off well before that, with low light performance slightly better per DXO at ISO 721 equivalent, versus 572 for the NX10.

In daylight and controlled environments, both generate crisp, vibrant photos with pleasing tonal rendition. At high ISOs, the Panasonic's newer Venus engine processing lends an edge in noise management, though the NX10’s raw files allow remarkable latitude after post-processing tweaks.

If image quality matters most, the choice depends on your subject and shooting environment: the GM5 offers more flexibility in dynamic range and high ISO, while the NX10’s APS-C sensor provides slightly better color fidelity and shallower depth-of-field for portraits.

Viewing Experience: Electronic Viewfinders and Touchscreens in Battle

What about framing and menus? Electronic viewfinders (EVFs) and rear screens are critical for composing shots accurately.

The Panasonic GM5 boasts a higher resolution EVF (1166k dots) with a 0.46x magnification, while the NX10’s EVF clocks in at 920k dots with a 0.57x magnification. The NX10’s larger viewfinder magnification provides a fuller, immersive view - perfect for manual focusing and outdoor shooting.

But the GM5 compensates with a 3-inch 921k fixed touchscreen - a boon for quick settings changes and intuitive focus point selection. Samsung’s NX10 also features a 3-inch screen but at a lower resolution (614k) and lacks touchscreen capability.

Notably, the GM5’s touchscreen-driven UI speeds up workflow in live view and focus settings. For photographers used to tapping and swiping on modern devices, this ergonomic advantage is significant. Yet, the NX10’s traditional button-driven interface, though less sleek, feels robust and responsive in challenging conditions.

Both models lack articulated screens, so you’ll need to get creative with angles.

Autofocus and Shooting Speed: Precision vs Pacing

Autofocus is where these cameras show their age - but with interesting differences.

The GM5 features a 23-point contrast-detection AF system with face detection and continuous AF options. Samsung’s NX10 has a 15-point contrast-detection system as well, but without continuous tracking or face detection.

In practical shooting tests, the GM5’s autofocus locks faster and more reliably on moving subjects. Its eye detection (though modest in functionality) helps portrait shoots capture crisp focus on eyes - crucial for character and emotional depth.

Burst speeds favor the Panasonic too: 5.8 frames per second vs NX10’s 3 fps. This faster rate proves invaluable when shooting wildlife or sports where decisive moments vanish quickly.

However, the NX10’s AF system is competent with static subjects and manual focusing is aided by a brighter EVF magnification, compensating somewhat for the slower AF speed.

Photography Discipline Performance: Who Excels Where?

Let’s break down how each camera behaves across popular photographic genres.

Portrait Photography

Portraits thrive on pleasing skin tones, bokeh quality, and focus on eyes.

The NX10’s larger APS-C sensor naturally produces shallower depth-of-field, enabling creamier background blur than the GM5. However, Micro Four Thirds lenses often have excellent optics and the GM5’s Venus engine handles skin tones smoothly, with less contrast-y rendering.

GM5’s eye detection autofocus enhances keeper rates in portraits. Meanwhile, the NX10 relies on careful manual or center-focused AF.

If portraiture is crown jewel, especially for casual or artistic portraits, the NX10 has an edge for bokeh. GM5 offers sharper renders and easier autofocus.

Landscape Photography

Dynamic range and resolution top the wishlist here.

The GM5’s 11.7 stops of dynamic range allow capturing intricate skies and shadow details without resorting to HDR stacking. Its 16MP resolution is sufficient for large prints or cropping flexibility.

Though the NX10’s APS-C sensor is larger, the marginally lower dynamic range and 15MP resolution make it slightly less versatile in tricky lighting.

Notably, neither camera offers weather sealing, so extra care is needed shooting landscapes in harsh environments.

Wildlife and Sports Photography

Quick autofocus and burst speeds are king.

GM5 emerges clearly better here - nearly double the frame rate and more autofocus points with continuous tracking. The 5.8 fps is fairly nimble for an entry mirrorless camera.

Samsung’s slower 3 fps rate and lack of AF tracking mean you’ll struggle with fast-moving subjects.

Street Photography

Discretion and portability count.

GM5’s tiny size and quiet operation make it the better candidate for unobtrusive street shooting. The NX10’s SLR-style girth and louder shutter can be obtrusive.

Both handle low light acceptably - GM5’s higher max ISO helps, but the NX10’s larger sensor has advantage with noise control at base ISOs.

Macro Photography

Neither camera specializes in macro, but the Panasonic GM5’s touchscreen aids in focusing precision at close distances. Lack of in-body image stabilization on both models means a sturdy tripod or optical lens stabilization is necessary.

Night and Astro Photography

High ISO noise performance and long exposure handling come into play.

GM5’s higher maximum shutter speed (up to 1/16000s electronically) and higher max ISO support creative night photography. Though no built-in bulb timer, manual exposure works well.

NX10 maxes at 1/4000s shutter and has max ISO 3200, which is more limiting.

Video Capabilities: Full HD Winner or Just Passable?

Video is another crucial factor.

The Panasonic GM5 records Full HD (1920x1080) at up to 60 fps in MPEG-4 or AVCHD formats, facilitating smoother motion and modern compression standards - something I tested in controlled environments, yielding clean footage for casual videography.

Samsung NX10 caps out at 720p (1280x720) at 30 fps with H.264 compression. The older generation sensor and processor limit its video appeal in 2024 standards.

Neither camera offers microphone input or 4K capabilities.

Lens Ecosystems and Compatibility

Lens choice often defines a camera’s usability.

Panasonic GM5 uses the Micro Four Thirds mount, compatible with over 107 native lenses as of now - a vast range stretching from affordable primes to pro telephotos. Panasonic and Olympus lenses have excellent reputations for optical quality and innovation.

Samsung NX10’s proprietary NX mount has about 32 native lenses, a surprisingly slim selection. Some lenses are hard to find new, limiting versatility and grip in specialty fields like macro or super-telephoto wildlife.

This lens ecosystem gap is pivotal: for the long term, GM5 offers more adaptability and investment security.

Build Quality, Weather Resistance, and Durability

Neither camera features official weather sealing, waterproofing, or shock/crush protection.

The NX10’s bulkier body feels more robust and less fragile in everyday beats; the GM5 compensates through good build finish but clearly favors ultralight over ruggedness.

If durability is mission-critical, consider an additional protective housing or carrying case regardless of choice.

Battery Life and Storage

Battery life metrics reveal practical shooting endurance.

The NX10 achieves approximately 400 shots per charge - impressive and ideal for extended shooting sessions in the field. Panasonic GM5 provides near 220 shots, notably shorter, requiring either extra batteries or careful power management.

Both use SD/SDHC/SDXC cards but have a single slot only.

Connectivity and Wireless Features

Modern connectivity is slim for both cameras.

GM5 includes built-in Wi-Fi and NFC for easy sharing and remote control - a useful feature for on-the-go photographers wanting instant transfers or smartphone control.

Samsung NX10 lacks built-in wireless but can achieve GPS tagging via optional modules.

Price-to-Performance: What’s the Right Value?

At release, the Panasonic GM5 retailed around $965; the Samsung NX10 was closer to $626 - a substantial price difference.

Today, prices have declined but the GM5 remains costlier. This premium can be justified by more modern features: higher resolution EVF, better AF performance, Full HD video, Wi-Fi, and a larger lens ecosystem.

If budget is tight and you mostly shoot static subjects or portraits outdoors, the NX10 can still deliver satisfying results.
