Panasonic GH2 vs Panasonic GM5: An Expert Comparison for Photographers in 2024

As an experienced camera reviewer who has tested thousands of mirrorless models over 15 years, I know the importance of digging beyond specs and marketing hype. Today, we’re examining two intriguing Micro Four Thirds systems from Panasonic’s past: the Panasonic Lumix DMC-GH2, announced in 2011 and an early flagship for video-focused enthusiasts, versus the Panasonic Lumix DMC-GM5, released in 2014, a compact choice aimed at discretion and portability.

Both cameras share Panasonic’s Micro Four Thirds lens ecosystem, but they cater to quite different types of photographers. In this comprehensive comparison, I’ll analyze real-world use, sensor and image quality, ergonomics, autofocus, video capabilities, and value – all backed by hands-on testing and deep technical knowledge. Whether you're a portrait shooter, landscape artist, travel photographer, or videographer, this guide will help you decide which Panasonic camera better fits your needs in 2024.

First Impressions & Handling: Size, Build, and Controls

Starting with the physical appearance and handling, the GH2 has a classic DSLR-style mirrorless body measuring 124x90x76 mm and weighing 442g. This camera offers a traditional grip and a sturdier feel that many users, especially those with larger hands, find comfortable for extended shooting sessions.

Conversely, the GM5 is truly pocketable, with a compact rangefinder design at only 99x60x36 mm and a featherweight 211g. This translates into the absolute opposite end of the size spectrum - ideal for minimalists or street photographers valuing discretion over control density.

When looking at the top of both cameras, the GH2 provides more conventional dials and buttons, giving tactile control over shutter speed, exposure compensation, and shooting modes. The GM5 streamlines these for portability but loses dedicated control dials, which can slow down rapid adjustments. The GM5’s minimalist approach benefits casual shooting but may frustrate experienced users who crave direct manual input.

Ergonomics Verdict:

• GH2: Better suited if you prioritize a robust grip, physical dial control, and traditional SLR-style handling.
• GM5: Best for ultra-compact convenience at the expense of some direct control, ideal if you want a camera that fits in a jacket pocket or purse.

Viewing and Display Technology

Both cameras boast a 3-inch LCD screen, but here’s where nuances emerge. The GH2’s fully articulating LCD with a resolution of 460k dots is ideal for creative angles and video framing, whereas the GM5’s screen is fixed but features a sharper resolution around 921k dots, leading to a crisper live view.

Moreover, the GH2 includes a moderate resolution electronic viewfinder (EVF) with 100% coverage and 0.71x magnification, useful for composing shots in bright light. The GM5 pushes ahead here with a higher resolution EVF - 1166k dots - but smaller magnification (0.46x), which means the image looks clearer but smaller in the viewfinder. If you shoot outdoors frequently or have eyesight sensitivity, GH2’s larger EVF might be more comfortable over long sessions.

Sensor and Image Quality: The Heart of the Matter

Both cameras share an identical Micro Four Thirds 17.3x13mm CMOS sensor with a resolution of around 16 megapixels, and both include an anti-aliasing filter to reduce moiré artifacts at the slight expense of ultimate sharpness.

From my testing, the differences in image quality arise largely from sensor readout speed, processor, and ISO performance:

• GH2 employs the Venus Engine FHD processor, optimized for earlier video capture but less efficient at noise reduction compared to modern standards.
• GM5, released three years later, includes an updated Venus Engine, resulting in an improved ISO ceiling of 25600 (vs GH2’s 12800), better dynamic range, and more refined color depth.

Practical Impact:

• Low light shots with the GM5 show cleaner shadows and better detail retention at ISO 3200-6400.
• Dynamic range in both cameras is commendable (~11.3-11.7 EV) but the GM5 pulls slightly ahead, resolving more highlight and shadow detail, especially when shooting raw.

Both cameras support raw capture, which is crucial for post-processing flexibility. However, the GM5’s improved sensor tuning means it delivers fresher, cleaner RAW files.

Autofocus System and Speed: Tracking Your Subject Reliably

Autofocus can make or break your shooting experience, especially in wildlife, sports, or street photography where moments are fleeting.

Both cameras feature:

• Contrast-detection autofocus only - no phase detection on either body.
• 23 AF points arranged across the frame.
• Face detection and live-view autofocus capabilities.

From practical use, the GM5’s updated processor enables faster autofocus acquisition and smoother continuous AF tracking compared to the GH2. The GM5 also supports touch-to-focus on its LCD, enhancing manual AF precision - a feature absent in GH2.

In the field:

• GH2 works well in good light but can struggle in low light or with fast-moving subjects.
• GM5 accelerates AF speed with better tracking fidelity, though still not ideal for high-speed sports or action compared to modern hybrid AF systems.

Neither camera supports advanced animal eye-detection AF, which limits wildlife portrait shooting performance.

Burst Rate and Buffer Depth

Continuous shooting speed matters when capturing fast action or fleeting expressions.

• GH2 shoots at 3 frames per second (fps), which is modest by today’s standards.
• GM5 doubles this to 5.8 fps, making it more suited to moderate action photography or time-lapse sequences.

Buffer capacities are limited on both, given their age - expect only a handful of raw frames before slowing down, which is adequate for casual action but insufficient for serious sports coverage.

Video Features: Who Leads the Lightweight Cinema Race?

Both Panasonic models earned early acclaim for their video capabilities, a hallmark of the GH line.

• The GH2 records Full HD 1080p up to 60fps using AVCHD or Motion JPEG codecs. It has a microphone input, allowing external mic use, essential for higher-quality audio recording.
• The GM5 also captures 1080p at 60fps but using AVCHD and MPEG-4. However, no microphone or headphone jacks are present, limiting audio control.

The GH2’s articulated screen provides more flexible video shooting angles; the GM5’s fixed screen is less adaptable for filmmaking.

Neither camera offers 4k or advanced video features by modern standards, but for basic HD recording, the GH2’s video-centric design still holds merit. The absence of in-body stabilization on both cameras demands stabilized lenses or external rigs for smooth footage.

Lens Compatibility and Ecosystem

Both cameras fit into Panasonic’s Micro Four Thirds (MFT) lens mount, affording access to an extensive selection of over 100 native lenses from Panasonic, Olympus (now OM System), and third-party manufacturers like Sigma and Voigtländer.

I found that:

• The GH2’s DSLR-style body encourages the use of larger professional lenses, including telephoto and fast primes, well-suited for wildlife and sports.
• The GM5’s compact size pairs well with Pancake primes and small zooms, perfect for travel and street photography.

This shared lens platform increases versatility, letting you tailor the system to different genres without reinvesting in a new lens collection.

Battery Life and Storage

Battery performance impacts how long you can shoot without interruptions.

• GH2’s battery is rated at about 330 shots, reflecting its more robust build and larger grip to hold a bigger battery.
• GM5 manages around 220 shots, less than the GH2, though respectable for such a tiny body.

Both accept SD, SDHC, and SDXC cards with single slots. No dual slots are featured, which might pose a limitation for professional shooters needing immediate backup.

Connectivity and Wireless Features

Connectivity is where the GM5 notably edges ahead:

• The GH2 lacks any wireless communication capabilities - no Wi-Fi, Bluetooth, or NFC.
• The GM5 incorporates built-in Wi-Fi and NFC, enabling remote shooting, image transfer to smartphones, and easy sharing.

While antiquated compared to today’s mirrorless cameras, GM5’s wireless features still provide a convenience not found on the GH2, especially for casual shooters who want quick social media uploads.
