Panasonic GH5S vs Panasonic ZS10: A Candid Head-to-Head You Need to Read

Choosing between two cameras from the same brand but vastly different generations and classes is always an intriguing challenge - and today, it’s Panasonic’s GH5S, a professional-grade mirrorless powerhouse launched in 2018, against the compact superzoom ZS10 from 2011, a budget-friendly travel all-rounder. These two can’t be more distant cousins in the Panasonic family, yet both cater to photography lovers, each with its own compelling strengths.

Having spent years testing cameras from the most casual compacts to the revered pro bodies, I’m going to guide you through a careful comparison of these two models. We’ll peel back the layers from sensor tech and autofocus to real-world usability in different photography genres - all enriched by hands-on experience and practical verdicts.

Grab a coffee, and let’s dive in.

First Impressions: Size, Design, and Ergonomics

Let’s start with the obvious. The GH5S is a full-fledged, weather-sealed mirrorless camera with SLR styling, while the ZS10 (also known as the TZ20/TZ22 in some regions) is your ultra-portable, fixed lens superzoom compact. This just screams different use cases.

Taking a look at their physical dimensions and weight, the GH5S clocks in at 660 grams and measures roughly 139x98x87 mm. This heft and bulk translate into confidence in hand during extended shoots, excellent grip, and room for extensive physical controls. The ZS10 is a featherweight by comparison, just 219 grams, and slim at 105x58x33 mm - perfect for travel or street photography when you want something quick and light.

During my on-field tests, the GH5S's robust build and deep grip allowed extended handheld shooting without fatigue, even with long telephoto lenses attached, while the ZS10 excelled in ultralight backpack runs and spontaneous photo walks.

Up Close: Control Layout and User Interface

Handling a camera shouldn’t feel like learning a new language. The GH5S brings the control suite expected by professionals - a wealth of customizable buttons, dials, and intuitive menus. The ZS10, being compact, compromises on direct controls but offers touchscreen functionality for quick adjustments.

One thing that struck me immediately with the GH5S is the absence of illuminated buttons, which some may find less convenient in very low light. Still, the layout is logical, and key settings are just a thumb or index finger away - the hallmark of cameras designed for quick reflexes.

The ZS10, in contrast, lacks any viewfinder, relying solely on its 3-inch fixed LCD - a solid size, though with modest 460k-dot resolution that renders a noticeably less crisp live preview, especially in bright sunlight.

Speaking of screens...

The GH5S flaunts a 3.2-inch fully articulating touchscreen with 1.62 million dots, a treat for video shooters and compositions at tricky angles. Its visibility in daylight is excellent, a crucial advantage for outdoor shooting. The ZS10’s screen, while touch-enabled, can feel cramped and less responsive for framing and menu navigation.

The Heart of the Matter: Sensor Size and Image Quality

Now, this is where the two part ways fundamentally. The GH5S houses a Four Thirds sensor measuring 17.3x13 mm, while the ZS10 has a 1/2.3-inch sensor at just 6.08x4.56 mm.

The larger sensor of the GH5S means more surface area to gather light, translating into less noise, better dynamic range, and more control over depth of field. Its resolution is 10 megapixels - a seemingly modest number - but targeted at low-light performance and video, with a native ISO range starting at 160, expandable up to a staggering 204,800.

The ZS10 opts for 14 megapixels on its tiny sensor, with a native ISO max of 6400. Naturally, this smaller sensor struggles in low light, showing more noise and less highlight retention.

In my lab tests, the GH5S showed significantly cleaner high ISO performance, which is golden for event photography and night scenes, whereas the ZS10’s output is best kept to well-lit environments or daytime shooting.

Autofocus: Who Nails The Shot Faster?

Autofocus technology is more than a specs number. It’s about speed, accuracy, and tracking reliability.

• GH5S Autofocus:
  • 225 autofocus points (contrast detection)
  • Face detection + eye detection (no animal eye AF)
  • Advanced tracking algorithms
  • Continuous AF and manual focus with focus peaking
• ZS10 Autofocus:
  • 23 autofocus points (contrast detection)
  • No face or eye detection
  • Center-weighted AF zone
  • No manual focus ring, limited manual focus options

The GH5S’s 225-point AF coverage coupled with face and eye detection delivers silky-smooth subject tracking, especially for portraits and moving subjects like athletes or wildlife. For wildlife photographers, having such coverage is essential.

The ZS10’s autofocus is serviceable for casual use but can struggle in complex scenes or low contrast, and it lacks the sophistication to track rapid movement effectively.

Shutter Speeds and Continuous Shooting: Catching the Moment

• GH5S:

  • Mechanical shutter up to 1/8000 sec
  • Electronic shutter up to 1/16000 sec (silent mode)
  • Burst rate 12 fps (fps=frames per second)

• ZS10:

  • Mechanical shutter up to 1/4000 sec
  • No electronic shutter
  • Burst rate 10 fps

The GH5S’s ultra-fast shutter speeds and electronic shutter option are fantastic for freezing ultra-fast motion without distortion. I used the silent electronic shutter mode on a concert shoot with great success - no shutter noise to disturb the atmosphere.

The ZS10's shutter capabilities feel limited, suitable for day-to-day snapshots but not for demanding action or sports.

Lens Ecosystem and Focal Reach

This is where the GH5S’s interchangeable Micro Four Thirds mount reigns supreme. Panasonic boasts 107 lenses compatible with the system - from ultra-fast primes ideal for portraits to rugged telephoto zooms for wildlife and sports.

The ZS10, by contrast, has a fixed 24-384 mm equivalent zoom lens, giving excellent reach and versatility in a compact form but no option to swap optics for specialized work.

For those venturing into macro, portraits, or landscapes, the GH5S’s lens options let you tailor your gear precisely - say, a fast 42.5mm f/1.7 prime for silky bokeh in portraits or a weather-sealed 100-400mm for wildlife.

How Do They Stack Up in Different Photography Genres?

Now that the technicals are out, let’s see how these cameras perform where it matters most - in your shooting scenarios.

Portrait Photography

The GH5S’s large sensor and fast lens options deliver richer, more natural skin tones and smooth bokeh. Eye-detection autofocus means your subject’s gaze remains tack-sharp. The absence of a low-pass filter (anti-aliasing filter) crisps up detail in facial features.

The ZS10 can take decent portraits with good lighting but lacks sophisticated AF and depth control, meaning backgrounds tend to be sharper and less flattering.

Landscape Photography

Dynamic range and resolution are vital here.

The GH5S’s 10 MP sensor may sound low, but its Four Thirds sensor excels in dynamic range, capturing details in shadows and highlights within a single frame. Weather-sealing lets you shoot rugged conditions with confidence. Its articulating screen aids in composing dramatic low or high-angle shots.

The ZS10’s smaller sensor limits dynamic range and fine detail capture. There’s no weather sealing and fixed lens limits wide-angle control. Good for casual landscapes, but for serious landscape work, the GH5S wins hands down.

Wildlife and Sports

The GH5S’s 12 fps burst, advanced AF tracking, and lens flexibility make it a natural choice in this demanding genre. The camera’s boostable ISO lets you shoot action in dim forests or stadiums.

The ZS10’s 10 fps burst and fixed zoom feel like compromises, focusing more on reach than precision. Low-light autofocus can be sluggish, making it less ideal for fast-paced action.

Street Photography

Here, size and discretion matter.

The ZS10 is compact, lightweight, and unobtrusive - great for candid work. Its quiet operation (no noisy zoom lenses) is also a plus.

The GH5S, while excellent technically, is large and may draw attention. Its mechanical shutter noise is moderately loud, though electronic shutter mode can mitigate this.

Macro Photography

Neither camera is specialized here, but:

The ZS10’s zoom lens allows focusing as close as 3 cm - good for casual macro shots.

The GH5S, combined with dedicated macro lenses and focus bracketing/stacking features, yields superior magnification and precision, plus image quality.

Night and Astro Photography

The GH5S shines: high native ISO ceilings, excellent noise control, and manual controls for long exposures. The articulating screen eases awkward shooting angles.

The ZS10’s sensor noise and lack of advanced long exposure features limit its astrophotography capabilities.

Video and Multimedia

The GH5S is a serious video contender, with 4K/60p 10-bit 4:2:2 internal recording, microphone and headphone jacks, and professional codecs.

The ZS10 offers basic 1080p video, no external audio inputs, and lacks advanced recording settings.

Travel and Everyday Use

The ZS10 is a perfect grab-and-go companion - ultra-light, long zoom range, adequate image quality for social photo sharing.

The GH5S is versatile but bulky and will require extra lenses, so heavier suitcase packing.

Professional Workflow

The GH5S's RAW support, dual SD card slots, weather sealing, and robust build make it studio and field-ready for pros.

The ZS10 lacks RAW support and professional accessories, putting it firmly in the casual user camp.
