Panasonic Lumix FZ70 vs. GM5: A Hands-On Comparison From My Photography Experience

When I first sat down to compare the Panasonic Lumix FZ70 and the Panasonic Lumix GM5, I knew this would be a clash of very different philosophies captured in camera bodies. Both hail from the same brand but cater to distinct photographic audiences - the bridge-camera enthusiasts craving reach and simplicity versus the mirrorless aficionados committed to sensor size and lens flexibility. Having tested each thoroughly across multiple genres and lighting conditions, this detailed comparison will break down what these cameras deliver in the real world, backed by technical insights only years of hands-on experience can provide.

Let’s dive in.

First Impressions: Size, Build, and Handling Dynamics

On paper, these cameras could not be more different: the FZ70 is a hefty little superzoom bridge camera while the GM5 is an ultra-compact mirrorless system.

The Panasonic FZ70 measures roughly 130 x 97 x 118 mm and weighs 606 grams - substantial but manageable. Its design follows a classic DSLR-like bridge format with a pronounced grip and large zoom ring, making one-handed telephoto shooting surprisingly comfortable despite the relatively small sensor.

Contrast that with the Panasonic GM5: a palm-friendly 99 x 60 x 36 mm cube weighing a mere 211 grams. The GM5 is admirably pocketable, especially paired with a pancake lens. Its rangefinder style lacks a deep grip, which can feel a bit fiddly over extended shooting, but the ultra-light body is a joy for travel or street photographers who prioritize discretion and mobility.

In terms of build quality, both bodies are predominantly polycarbonate. Neither offers weather sealing or rugged protection, so they should be handled with care in adverse conditions. However, the GM5’s compactness gives it a modern air of refinement, whereas the FZ70’s bulk leans on traditional ergonomics aimed at users wanting a one-stop all-in-one option.

A Look from Above: Control Layout and Usability

Controls can make or break a shooting experience. I placed particular emphasis on this aspect as I moved between these two cameras.

The FZ70 sports a comprehensive control layout, including dedicated buttons for exposure modes, a top dial, and a zoom lever integrated with the shutter - a convenience for quickly re-framing shots. Physical buttons for ISO, White Balance, and Exposure Lock provide tactile access, reducing menu diving during active shooting.

The GM5 trims this down to essentials, reliant on its with touchscreen interface. It integrates fewer physical buttons, banking on a smartphone-style menu navigation. For users familiar with smartphones and tablets, this is intuitive; for photographers who prefer dedicated dials and buttons, it can slow workflow. That said, the GM5 does include a respectable electronic viewfinder (EVF) with decent resolution and magnification that greatly aides composing in bright outdoor light.

The takeaway: If your workflow values dedicated tactile controls and rapid access, the FZ70 treads a more user-friendly path, whereas the GM5 sacrifices some immediacy in favor of compactness and modern touchscreen convenience.

Sensor and Image Quality: Tech Specs meet Field Results

This is where the rubber truly hits the road for the two cameras, and the difference in sensor technology is stark.

The FZ70 uses a tiny 1/2.3” sensor typical of compact superzoom cameras. While 16 MP might sound respectable, the pixel pitch is quite small. Result? Limited dynamic range and higher noise at ISO beyond 400–800. The camera performs well in sunny outdoor shots but struggles with shadow detail retrieval, especially in landscape or indoor ambient light conditions.

On the other hand, the GM5’s Four Thirds sensor is roughly eight times larger in surface area. This bigger sensor naturally gathers more light, enabling better image quality, extended ISO range, and higher dynamic range. Its 16 MP resolution is similar on paper but the larger sensor footprint translates to superior color depth and noise performance - photographically very noticeable from the first frame.

In practical field tests, the GM5’s images exhibited cleaner high ISO results and better ability to preserve highlight and shadow details in challenging lighting - important for expressive portrait and landscape work.

LCD and Viewfinder: Composing and Reviewing Your Shots

Both cameras incorporate electronic viewfinders and LCD displays but differ in quality and utility.

The FZ70’s rear 3-inch, 460k-dot fixed TFT LCD is serviceable but low resolution by today’s standards. It’s not touch-enabled, making menu navigation less fluid. The 202k-dot EVF is similarly basic - wide enough but somewhat pixelated.

The GM5 shines here, with a 3-inch, 921k-dot fixed touchscreen LCD offering bright, high-resolution preview and responsive interface control. The 1166k-dot EVF with 0.46x magnification delivers a crisp, natural view enhancing accuracy during framing.

For street or travel photography where quick composition and review are vital, the GM5’s better screen and EVF markedly improve usability. The FZ70’s outputs feel more utilitarian and dated in comparison, limiting creative flexibility especially in bright or low-light scenarios.

Autofocus Performance: Speed, Accuracy, and Tracking

Autofocus remains key to nearly all photographic applications. I tested both cameras in variable lighting, tracking moving subjects, and manual focus override scenarios.

The FZ70 offers a contrast-detection based AF system with 23 points, face detection, continuous AF, and tracking. It performs acceptably in good light but exhibits hunting in low-light or with quickly moving subjects, especially at long zoom ranges.

In contrast, the GM5 also uses contrast detection AF with 23 points but couples this with touch-based AF point selection and live view AF improvements, resulting in faster and more reliable focusing in practical use. It also supports continuous AF and face detection effectively.

Despite neither employing phase-detection AF (still uncommon in these older models), the GM5’s smaller lens flange distance and more powerful processor pairing yield better performance for wildlife, sports, and street photography where quick subject acquisition is essential.

Lens System and Optical Versatility

Lens options define the ecosystem aliens see, and here the gulf is dramatic.

The FZ70 comes with a fixed 20-1200mm (60x zoom) lens, enabling enormous reach in a single package. Aperture ranges from F2.8 at wide to F5.9 at telephoto. This type of extreme zoom is perfect for casual wildlife snapshots, travel photos spanning landscapes to distant subjects, or when packing light is key and interchangeable lenses are a no-go.

The GM5 lacks a built-in lens but uses the Micro Four Thirds mount, granting access to over 100 lenses from Panasonic, Olympus, and third parties. This includes everything from ultra-wide primes and fast portrait lenses to super telephotos and dedicated macro glass.

While the FZ70’s fixed-lens convenience is undeniable, the GM5’s system flexibility opens doors for professional portraiture, landscapes, macro photography, and studio work - the kind of tailored optics serious photographers demand.

Build Quality and Weather Resistance in Real Conditions

Neither camera features weather sealing or rugged protection. Both require careful handling around dust, moisture, or shocks.

I found the FZ70’s solid grip gave confidence for handheld telephoto shots, but the lack of environmental sealing means caution is required outdoors. The GM5’s lighter frame demands a lens with weather resistance if shooting in inclement weather.

So, neither fills the pro rugged shooter niche, but the GM5’s compactness and accessory compatibility allow you to build a more protective kit with weather-sealed lenses.

Battery Life and Storage: Staying Powered on the Go

Battery endurance is often underestimated until your shoot gets real.

The FZ70’s battery life rated at 400 shots per charge proved generous in real world use - ideal for touring or event coverage where charging opportunities may be irregular.

The compact GM5 tops out at around 220 shots per charge, pretty average for mirrorless cameras its size. For longer outings, carrying spare batteries becomes a necessity.

Both use standard SD / SDHC / SDXC cards and have a single card slot, so storage expansions are identical.

Video Recording Capabilities

Neither camera targets the video enthusiast, but basics are covered.

The FZ70 records Full HD 1920 x 1080 video at interlaced 50i/60i and progressive formats 25p/30p, using MPEG-4 and AVCHD codecs. No 4K or advanced stabilization beyond optical IS.

The GM5 shoots Full HD 1080p at 24/25/30/50/60 frames per second, in MPEG-4 or AVCHD. The choice of frame rates is broader, slightly more appealing for casual video. No headphone or microphone jacks limit audio quality management.

Neither supports in-body stabilization; GM5 relies on lens IS.

Practical Use in Different Photography Genres

Let me break down how these cameras perform across major photography types based on my hands-on testing.

For quick, grab-and-shoot scenarios demanding extreme reach, the FZ70 excels. For image quality, adaptability, and creative freedom, the GM5 is a smarter choice.

The Value Proposition and Who Should Buy Each

The Panasonic Lumix FZ70, priced around $300, stands out as a budget-friendly superzoom with good ergonomics and solid feature set for the casual shooter or traveler who wants everything-in-one without worrying about lenses.
