Choosing between the Panasonic Lumix DMC-FZ200 and the Panasonic Lumix DMC-GH3 is a compelling yet challenging decision. Both cameras arrived in 2012, bringing unique feature sets aimed at different photographers. As someone who has tested thousands of cameras over 15+ years, including both these models extensively, I’ll navigate you through every major aspect - from sensor tech and autofocus to real-world applications in genres like portrait, wildlife, and video work.

My goal is to help you pick the camera that truly matches your photographic style, needs, and budget. Let’s dive in.

First Impressions: Size, Handling & Ergonomics

The FZ200 and GH3 both offer rugged, SLR-style bodies but cater to distinct user experiences.

Panasonic FZ200:

• Bridge camera with fixed 24× superzoom (25-600mm equivalent).
• Compact for a travel zoom at 125x87x110mm, weighing 588g.
• Ergonomics focused on one-handed superzoom ease, with a firm grip but limited external controls.

Panasonic GH3:

• Mirrorless camera with Micro Four Thirds mount, allowing lens swaps.
• Larger body at 133x93x82mm but lighter at 550g.
• More buttons and dials offer tactile control favored by enthusiasts, plus a deeper grip.

In my handling tests, GH3 felt more balanced with heavier lenses, while FZ200’s fixed lens made it ultra-portable and ready to shoot quickly without fuss. If you prioritize compactness and everything-in-one simplicity, the FZ200 excels; if customizable control and lens freedom matter, GH3 takes the lead.

Design & Control Layout: Intuitive vs. Advanced

The top plate of each camera tells a story.

• FZ200: Simple but effective layout. A mode dial, shutter speed, and exposure compensation dials are present, but no top LCD panel for detailed settings.
• GH3: More complex, with a high-res OLED screen and multiple custom buttons. The touch-sensitive articulated rear screen adds a modern handshake with user interface, rare at its release time.

For professionals accustomed to manual controls and quick adjustments mid-shoot, the GH3’s button placement and touch interface outperformed FZ200 in my shooting tests. However, beginners or casual shooters will find FZ200’s straightforward design less intimidating.

Sensor & Image Quality: Size Matters

Image quality broadly comes down to sensor size, technology, and processing. Here’s the technical comparison of sensor specs:

What this means in practice:
The GH3’s Four Thirds sensor is significantly larger than the FZ200’s 1/2.3" sensor, providing better image quality, lower noise, and improved dynamic range. In tests under varying light, GH3 delivered cleaner images at higher ISOs, making it a strong choice for low-light scenarios. The FZ200’s smaller sensor limits its low-light prowess and fine detail, but paired with its bright constant f/2.8 lens across the zoom range, it remains usable in challenging lighting.

For landscape and professional photography where image quality leads, GH3 is dominant. The FZ200 suits casual shooters appreciating superzoom convenience.

Display & Viewfinder: Flexibility Meets Clarity

Both cameras sport articulating screens which are vital for creativity in tricky angles.

• FZ200: A 3” free-angle TFT LCD with 460k dots - adequate but not very sharp. No touchscreen capability.
• GH3: A 3” fully articulated OLED touchscreen with 614k dots, offering much richer color and contrast.

The GH3’s live view is more responsive with touch autofocus and menu navigation, which I found invaluable for video and macro work. Both have EVFs, but the GH3’s is brighter and higher resolution (1744 vs 1312), improving framing and focus in bright daylight.

For viewing comfort and versatility, GH3 wins again.

Autofocus Performance: Precision vs Speed

Both Panasonic cameras use contrast-detection AF systems (no phase-detect on sensor here), but GH3 leverages more advanced algorithms.

In my field tests - shooting portraits, wildlife, and street scenes - GH3 consistently acquired focus quicker and with less hunting, especially in continuous AF. The touch AF on the GH3 speeds pinpointing subjects in live view.

The FZ200’s AF was reliable in well-lit, static subjects but lagged with fast-moving action and close macro targets. Its limited AF modes constrain customization.

Lens Ecosystem and Flexibility

• Panasonic FZ200: Fixed 25-600mm equivalent f/2.8 zoom lens; superb optical versatility but no option to change lenses.
• Panasonic GH3: Micro Four Thirds mount unlocks a broad array of lenses (over 100 compatible), including primes, telephotos, macros, and pro optics.

For photographers wanting creative freedom, the GH3’s lens system is an enormous advantage. I’ve personally tested GH3 with everything from fast 42.5mm f/1.2 portrait lenses to 300mm wildlife glass, finding it a versatile field partner.

However, if lens changing complexity or cost is a concern, the FZ200’s ready-to-use all-in-one lens suits travel and casual shooting well.

Burst Shooting & Continuous Capture

Action photographers assess continuous shooting as a make-or-break feature.

The GH3’s 20fps burst in low resolution mode exceeds most mirrorless competitors of its time, useful for sports or wildlife where catching decisive moments counts. The FZ200’s 12fps is impressive for a bridge camera but hampered by buffer limits and slower write speeds.

My tests showed the GH3’s burst more suited to critical action capture; FZ200 better for spontaneous shooting, but not for extended fast-action bursts.

Video Capabilities: Going Beyond Stills

Both cameras deliver Full HD video but differ in codec options, audio features, and usability.

For hybrid shooters, GH3 is the stronger video platform. The headphone jack allows audio monitoring, critical for pro videographers. Its time-lapse feature and richer codec support simplify advanced workflows.

FZ200 has lens-based optical IS aiding smooth footage, a plus given the GH3's lack of in-body stabilization (IBIS). However, I found GH3’s video autofocus smoother with face detection and touch focus.

Battery Life & Storage: Ready for the Day

Both cameras use proprietary battery packs with equal stated endurance (approx. 540 shots CIPA rating).

• Storage: Both support SD/SDHC/SDXC cards; neither offers dual slots.
• Connectivity: FZ200 lacks wireless (no Wi-Fi), while GH3 has built-in Wi-Fi for image transfer and remote control.

For travel photographers and professionals on the go, GH3’s wireless feature is a convenience I found increasingly essential during shoots and quick social media sharing.

Durability & Weather Sealing

Only the GH3 features environmental sealing, making it splash and dust resistant. The FZ200 has no weatherproofing.

This makes GH3 a more reliable companion for outdoor and adverse weather conditions, a fact I can’t stress enough after testing in rugged environments.
