A Tale of Two Cameras: Panasonic GH5S vs. Sony H300 - An Expert’s Hands-On Comparison

When it comes to choosing a camera, few decisions are as personal and nuanced as picking the right tool for your photography style, budget, and aspirations. Today, I’m putting two very different cameras head-to-head: the Panasonic Lumix DC-GH5S and the Sony Cyber-shot DSC-H300. At first blush, this might feel like comparing apples and tractors - they serve vastly different purposes - but that’s exactly what makes this comparison both interesting and instructive.

Having tested thousands of cameras over my 15 years in the field, I want to distill what each of these cameras offers in the real world, how their specs play out in everyday shooting, and who should seriously consider adding them to their kit. Spoiler alert: Neither is inherently “better” than the other - they’re designed for different users and come at wildly different price points. So, buckle up as we zoom from high-end professional mirrorless to budget-friendly superzoom bridge style, covering all critical points with technical insights, hands-on impressions, and - most importantly - practical buying advice.

Looking at the Basics: What Are These Cameras?

Before diving deep, let’s set the stage with a quick overview:

Right off the bat, you can tell these cameras live in very different worlds.

Physical Handling and Ergonomics: Clubs for Thumbs or Sleek Precision?

When I pick up the Panasonic GH5S, it feels like an extension of my professional gear set: firm grip, well-placed controls, and a solid chunk of metal making it rugged yet comfortable. The body measures 139x98x87mm and weighs in at 660 grams - not feather-light, but certainly manageable for all-day shoots. Its ergonomic design makes it easy to hold with gloves in challenging outdoor conditions, a vital point for serious landscape or wildlife shooters.

Conversely, the Sony H300 reminds me of one of those “large bridge cameras” that try to imitate DSLRs in form but feel decidedly plasticky and less confidence-inspiring in the hand. It’s slightly lighter at 590 grams and about the same size (130x95x122mm) but sports a chunky plastic build with a fixed 30x optical zoom. It’s easy to tote around casually, but I wouldn’t trust it for anything demanding or professional. The fixed lens means fewer controls to fiddle with - great for beginners but limiting for serious creatives.

Verdict: For tactile satisfaction and versatile operation, GH5S wins hands-down. The H300 caters more to casual shooters needing simplicity and reach.

Sensor Technology and Image Quality: The Heart of the Matter

The heart of any camera is its sensor, and the Panasonic GH5S packs a Four Thirds-sized 10MP CMOS sensor optimized for video and low-light performance, even though the resolution is relatively modest compared to trendier models. This lower megapixel count actually benefits noise handling and dynamic range, especially useful in night, astro, and cinematic work. Its sensor surface area is roughly 225 mm² - vastly larger than Sony’s 28 mm² sensor - and this translates into bigger photodiodes capturing more light per pixel, crucial for clean images at high ISO.

On the Sony H300 side, we’re looking at a tiny 1/2.3-inch CCD sensor (6.17x4.55 mm), which inherently limits image quality despite a higher nominal resolution of 20MP. More pixels crammed on a tiny sensor usually mean more noise and less dynamic range, especially in shadows or dim-light scenarios. This sensor performs best under bright daylight but struggles with noise quickly as ISO increases, with a maximum native ISO at 3200 but questionable usability above 800.

Comparison images illustrate these points well:

Real-world testing: Shooting ISO 6400 handheld on the GH5S yielded sharp, crisp results with manageable noise, perfect for event or concert photography. The H300’s best results came at ISO 100-200 under bright skies; indoors or low light, images were muddy with color shifts and blown highlights.

Verdict: For image quality and adaptability, GH5S is leagues ahead, especially at high ISOs and in challenging light. The H300 is best reserved for bright daytime scenes and casual snaps.

Autofocus Systems: Precision vs. Simplicity

The Panasonic GH5S boasts a contrast-detection autofocus system with 225 focus points, offering face detection, eye-AF (eye detection autofocus), and continuous tracking. While it lacks phase-detection AF found on many recent cameras, its AF system excels in low-light conditions and video recording, providing smooth and reliable performance when tracking moving subjects. I’ve had fantastic success using it for portrait and wildlife shoots, where eye detection can make or break the shot.

In contrast, the Sony H300 has a much simpler autofocus system, relying on contrast detection with a few selectable AF points. Its lack of continuous AF and slow focusing speed make it frustrating to use for action, sports, or wildlife. Face detection works decently under good light but falters quickly in shadows or complex scenes.

Testing notes: The GH5S locked focus in under 0.2 seconds on average, tracking runners at a local track effectively. The H300 struggled to focus quickly even on static subjects indoors, and in dim lighting, focus hunts were common.

Verdict: For any serious AF-demanding discipline like sports, wildlife, or portraits needing sharp eyes, the GH5S is the clear winner.

Handling Different Photography Genres

Photography is about capturing moments in various styles and environments. Let’s explore how these two cameras perform across genres:

Portrait Photography

The GH5S’s 10MP sensor, paired with Micro Four Thirds lens selection offering wide apertures (f/1.2-f/2.8 primes), delivers creamy bokeh and pleasing skin tones. The camera’s robust face and eye-detection autofocus ensures tack-sharp eyes automatically, a blessing when you’re juggling lighting and framing. Plus, its accurate exposure metering and custom white balance let you capture natural-looking skin tones without needing heavy color grading.

Meanwhile, the Sony H300 has a fixed lens with variable f/3-5.9 aperture, forcing smaller apertures and less depth of field separation. The result is flatter portraits with smaller background blur - fine for casual family snapshots, but not studio-quality portraits. Face detection helps focus, but image quality and bokeh are uninspiring.

Landscape Photography

This is where the GH5S shines for enthusiasts and pros alike. Its sensor captures wide dynamic range, enabling retrieval of highlight and shadow detail in challenging scenes. The robust weather sealing lets you shoot in fog, rain, or dusty environments without fuss. Additionally, the Micro Four Thirds ecosystem offers plenty of sharp wide-angle and ultra-wide prime lenses, essential for dramatic landscapes.

The H300’s small sensor and limited ISO range restrict its ability to capture detailed, broad dynamic range panoramas. It’s also not weather-sealed, so challenging environments are out. However, its versatile 25–875 mm equivalent zoom means you can frame distant landscape details easily - at a big cost in quality.

Wildlife Photography

The GH5S is better suited here with decent burst speed (12fps), reliable continuous AF tracking, and compatibility with long telephoto lenses from the MFT line, although it requires more investment. Its 2.1x crop factor means moderate telephotos reach farther. Moreover, its silent electronic shutter helps avoid spooking animals.

The H300’s 35x zoom is impressive for a budget camera but can’t match professional lens sharpness or autofocus speed. Burst shooting is limited to single frames, and it has no AF tracking for moving wildlife.

Sports Photography

Sports is one of the toughest disciplines and demands fast autofocus, high continuous shooting rates, and robust buffer capacity. The GH5S’s ability to shoot 12 frames per second combined with reliable continuous autofocus allows capturing critical moments of fast action. Low-light sensitivity is excellent for indoor sports arenas.

The Sony H300 has no continuous shooting mode beyond one frame per exposure and no AF tracking, making it unsuitable for action photography.

Street Photography

Here the smaller and lighter H300, despite its bulkiness, has some appeal to casual street shooters due to its built-in zoom and point-and-shoot ease. But its loud shutter, lack of silent shooting modes, and limited low-light capacities are drawbacks in candid situations.

The GH5S, though bigger, offers a fully articulated touchscreen and silent electronic shutter mode for discretion. Combined with compact primes, it can be a versatile street shooter.

Macro Photography

Neither camera excels specifically in macro. The GH5S, paired with specialized MFT macro lenses, delivers professional-level close-ups with precise focusing and good stabilization (from compatible lenses, since GH5S lacks in-body IS). The Sony H300 does have optical image stabilization but fixed lens capability and no dedicated macro mode limit its utility.

Night and Astrophotography

If you dabble in nightscapes or astrophotography, GH5S’s high ISO performance, dark sky noise control, and exposure bracketing help create stunning results. Its 10MP sensor is optimized for clean long exposures. The H300’s tiny sensor, limited highest ISO, and lack of RAW file support severely restrict night usage.

Video Capabilities

This is where the Panasonic GH5S was truly born to perform. It supports 4K 60fps video at 150Mbps with professional codecs, full manual control over exposure, and has headphone & microphone jacks for quality audio capture. Its fully articulating touchscreen helps with vlogging and dynamic framing.

The Sony H300 maxes out at 720p 30fps with MPEG-4 compression, which feels dated and extremely limiting by today’s standards.

Travel Photography

Surprisingly, the lightweight Sony H300’s fixed superzoom lens and simple controls make it a compelling choice for the cheapskate traveler who wants lots of zoom versatility in a single package without changing lenses or carrying extras. Battery life is decent at 350 shots.

The Panasonic GH5S, while heavier and more complex to operate, offers unmatched flexibility thanks to the interchangeable lens ecosystem, excellent image quality, and weather sealing, but at a hefty price premium and greater weight to carry.

Professional Workflows

The GH5S outputs professional ProRes-equivalent MOV files, offers dual SD card slots with UHS-II support for fast write speeds and backup, and integrates well with modern editing pipelines. It supports RAW shooting and fine customization for advanced users.

The Sony H300 does not support RAW and only offers a single SD card slot (plus some lesser format support). Its JPEG-only outputs limit postprocessing flexibility.

Build Quality and Durability: Braving the Elements

The Panasonic GH5S is distinctly built for the professional user who demands durability. Its magnesium alloy body comes fully weather sealed against dust and moisture - crucial when you’re shooting outdoors in unpredictable conditions such as during landscape expeditions or wildlife safaris.

The Sony H300 feels more consumer-grade with a plastic build, no environmental sealing, and somewhat fragile controls. It’s great for casual use but not rugged enough for serious adventure travel or professional gig work.

Battery Life and Storage: Keeping You Shooting

GH5S’s manufacturer rating of approximately 440 shots per charge aligns well with my real-world experience (slightly less when shooting video and using the screen heavily). Dual SD card slots allow either overflow or instant backup, an invaluable feature for pros who can’t risk losing images.

The Sony H300 clocks in at about 350 shots per full charge, with a single SD or Memory Stick slot. If you are on the fly and can’t recharge often, this camera might let you stretch shooting time without lugging heavy batteries, but it lacks redundancy.

Connectivity and Extras: Wireless, Ports, and Workflow

The GH5S offers built-in Wi-Fi and Bluetooth, allowing easy in-camera image transfer and remote control via smartphone apps - a huge plus for event shooters or vloggers. It boasts USB 3.1 for fast tethered transfer, HDMI output, plus microphone and headphone jacks to control sound quality during video recording.

Sony’s H300 is more basic: no wireless connectivity, older USB 2.0 port, HDMI output present but no audio input options. For casual users, it’s enough, but it lacks the modern bells and whistles that serious multimedia creators want.

Price vs. Performance: What Are You Paying For?

The biggest elephant in the room is cost. The Panasonic GH5S retails around $2,500, while the Sony H300 is less than $250. That tenfold price difference represents hugely different user expectations and capabilities.
