Panasonic GM5 vs Samsung NX500: An In-Depth Mirrorless Camera Showdown

Choosing the right mirrorless camera is a pivotal decision for photography enthusiasts and professionals alike. In this comprehensive comparison, I delve into two notable entry-level mirrorless models: the Panasonic Lumix DMC-GM5 and the Samsung NX500. Both pack unique features and capabilities but cater to slightly different user needs and photographic styles.

Drawing from hands-on testing with both cameras in various real-world scenarios, I’ll dissect their sensor architectures, autofocus systems, handling, image quality, video prowess, and overall ergonomics. By the end, you’ll have a clear sense of which camera might fit your shooting style and workflow best.

First Impressions: Design and Ergonomics Matter

When you pick up a camera, the feel and layout can shape your creative experience profoundly. Let’s start by comparing these cameras’ physical characteristics.

Compactness and Build

The Panasonic GM5 is heralded for its remarkable compactness. Sporting a slim rangefinder-style body, it measures just 99 x 60 x 36 mm and weighs a mere 211 g. This makes it one of the smallest Micro Four Thirds mirrorless cameras I've tested, ideal for street photographers and travelers valuing discretion and light packing.

The Samsung NX500, in contrast, is larger at 120 x 64 x 43 mm and weighs 287 g. While still portable, it commands a chunkier presence thanks to its more robust construction. The NX500’s grip is more pronounced, which I found lends better handling during extended shoots or when using heavier lenses.

The GM5 features a classic control layout with minimal buttons, leaning on its touchscreen for quick adjustments. Panasonic’s Venus Engine powers responsive menu navigation, though the absence of an articulated or tilting screen limits framing flexibility from unusual angles.

Conversely, the NX500 incorporates a tilting 3-inch touchscreen with higher resolution, enhancing usability for video and vlogging scenarios. Its top dials and buttons provide physical control over exposure settings, appealing to photographers who prefer tactile interfaces.

Quick Summary:

If you're seeking ultra-portability above all, the GM5 shines. But if comfort during long sessions and flexible controls matter more, the NX500 edges ahead.

Sensor and Image Quality: Does Size Really Matter?

Image quality starts with the sensor, and here the two cameras take decidedly different approaches.

Sensor Size and Resolution

The Panasonic GM5 features a Four Thirds CMOS sensor measuring 17.3 x 13 mm with 16-megapixels. While smaller than APS-C or full-frame sensors, Four Thirds chips enable compact system designs and generally offer good sharpness at base ISO.

The Samsung NX500, on the other hand, houses a larger APS-C BSI-CMOS sensor (23.5 x 15.7 mm) with a high resolution of 28 megapixels and no anti-aliasing filter. The broader sensor surface area improves light-gathering ability and generally bolsters dynamic range and low-light performance.

Real-World Image Quality Observations

In my tests, the NX500 consistently delivered crisper images with more detailed textures, thanks to the higher resolution and larger sensor. The lack of an anti-aliasing filter means extra crispness but at a slight risk of moiré in fine patterns - a trade-off many photographers appreciate.

The GM5, while good within its class, exhibited slightly softer images with more noticeable noise creeping in at ISO 1600 and above. Its dynamic range is respectable but clearly behind the NX500, especially in retaining highlight details under harsh lighting.

Color depth and tonal gradations also favored the NX500, yielding richer skin tones and vibrancy without oversaturation. Panasonic’s color science here felt more muted but neutral.

ISO and Noise Handling

• GM5: Native ISO 200–25600, with usable image quality up to ISO 1600; noise becomes apparent beyond.
• NX500: Native ISO 100–25600, expandable to ISO 51200; maintains cleaner files at ISO 3200 and even 6400 by comparison.

Autofocus and Burst Shooting: Capturing Fast Moments

As action photography demands sharp, speedy autofocus and fast frame rates, these specs warrant close scrutiny.

Autofocus System

The Panasonic GM5 employs a contrast-detection-only autofocus system with 23 focus points. It supports face detection and touch AF, working well in well-lit scenes but noticeably slower and prone to hunting in dimmer settings.

Samsung’s NX500 upgrades this with a hybrid autofocus system combining contrast and phase detection via 209 focus points scattered across the frame. This translates into snappier and more reliable focusing across various scenarios, including tracking moving subjects like athletes or wildlife.

Continuous Shooting

• GM5 tops out at 5.8 frames per second, which is decent for casual sports or street action.
• NX500 pushes the envelope with 9 fps, allowing more opportunities to capture peak moments.

I found the NX500’s burst mode and AF tracking notably better for capturing wildlife on the move, resulting in more keepers per session during my test shoots.

Viewfinder and Display: How You Frame Your Shots

Complex scenes often require precise framing and composition aids.

Viewfinder Options

The GM5 includes a built-in electronic viewfinder (EVF) with 1.16M dots and 100% coverage - a boon for bright outdoor shooting when LCD glare becomes an obstacle. Its magnification rate of 0.46x is average but adequate.

The NX500 lacks any native viewfinder. You must rely solely on the rear display, which can be limiting in bright sunlight or for photographers accustomed to eye-level shooting. This absence may be a dealbreaker for some.

LCD Screen Capabilities

Both cameras have 3-inch touchscreens, but the NX500’s tilting mechanism is a clear advantage for low-angle or overhead shots, selfies, and video monitoring. The GM5’s fixed screen is sharp but less versatile.
