Panasonic GH5S vs Panasonic GF8: A Deep Dive into Two Worlds of Mirrorless Cameras

When it comes to Panasonic’s Micro Four Thirds lineup, the choices span a wide spectrum - from enthusiast-friendly rangefinders grooming social media mavens to rugged pro-level behemoths engineered for serious video and stills work. Today, we pit two seemingly opposite beasts against each other: the Panasonic Lumix DC-GH5S, a professional mirrorless powerhouse announced in 2018, and the humble 2016 Panasonic Lumix DMC-GF8, an entry-level mirrorless designed for casual shooters and vloggers. At first glance, these two cameras couldn’t be more different in intent, yet both bear Panasonic’s distinct design language and a shared Micro Four Thirds heritage. The question is, how do they stack up if you’re trying to choose your next camera? Let's saddle up and explore their strengths, weaknesses, and who exactly each camera was made for.

Size and Ergonomics: The Battle of Bulk vs. Boutique

First things first - if you’re a traveler, street photographer, or someone who just doesn’t want to lug around a brick, size and comfort matter a lot. The Panasonic GH5S weighs in at a solid 660 grams and measures approximately 139 x 98 x 87 mm. In sharp contrast, the GF8 comes across almost like a pocket whisperer, weighing just 266 grams and squeezing itself into a petite 107 x 65 x 33 mm frame.

Using the GH5S for hours feels like wielding a serious tool - think a DSLR with a modern twist: robust, grippy, packed with buttons that are well positioned for rapid access during shoots. In contrast, the GF8’s lightweight, minimalist rangefinder-style body makes it effortlessly portable. Ergonomically, the GH5S sports a deeply sculpted grip that welcomes your hand in a way that turns every button press into muscle memory. GF8’s slim line and flat front mean that while it feels sleek, it may feel less stable during longer sessions, especially with heavier lenses.

The GH5S's heft lends comfort during handheld video shoots and rapid still captures, while the GF8 targets casual photographers who prize convenience and ease of carry above all else. So if you live out of a backpack and want something that almost disappears into your palm, the GF8 wins on sheer portability.

Design and Control Layout: Pro Controls vs Simplicity

If you thought size was the only difference, wait until you see the control layout. Panasonic’s experience with professional users shines through in the GH5S’ dedicated dials for ISO, shutter speed, exposure compensation, and an intuitive top LCD panel which mirrors vital shooting info. This allows for quick adjustments without diving into menus.

Conversely, the GF8 has a pared-back top deck with fewer dedicated controls and no electronic viewfinder. The tilting screen compensates by allowing touchscreen control of menus and focus points. Although simple to navigate, users wanting immediate access to exposure tweaks will find the GF8 a step behind.

The GH5S’s illuminated buttons (sadly lacking) are a minor quibble because the button layout itself is highly functional - customizable buttons enhance workflow and make shooting a tactile joy. GF8 users will rely more on touchscreen navigation, which is smooth but less satisfying if you're accustomed to tactile control during action moments.

Sensor and Image Quality: Size Isn't Everything

Both cameras employ a Four Thirds sensor measuring 17.3 x 13 mm with a focal length multiplier of roughly 2.1x, but image quality tells a different tale.

The GH5S uses a 10.2-megapixel sensor specifically engineered for high sensitivity, designed to excel in low-light and video scenarios. Panasonic borrowed dual native ISO technology here to minimize noise at higher ISOs, a feature absent in the GF8. The GH5S’s sensor lacks an anti-aliasing filter - a design choice that enhances sharpness at the cost of some moiré, which you can usually mitigate in post-processing.

The GF8, by contrast, boasts a higher resolution 16MP sensor with an anti-aliasing filter, delivering crisp images with less risk of moiré but potentially a hair less fine detail rendering. The pixel count advantage favors print sizes and cropping flexibility, but the GH5S’s optimized sensor shines when pushing ISO or shooting video.

In practical terms, I found the GH5S’s images less noisy at ISO 6400 and above, making it excellent for dimly lit venues or night photography. The GF8 starts showing noise sooner (from ISO 1600 upwards), more suited to daylight or well-lit indoor situations.

Autofocus Systems: Precision vs. Convenience

The GH5S features a sophisticated contrast-detection autofocus system with 225 focus points - quite dense for Micro Four Thirds - and offers face detection, touch focus, and continuous AF. However, it doesn’t have the hybrid phase detection AF systems found in some competitors. The lack of phase detection means AF speed isn’t the blistering lightning-fast kind but remains accurate and reliable, especially during video.

In contrast, the GF8 has a much simpler contrast-detection AF with 23 focus points - sufficient for beginner usage but less versatile or speedy when chasing dynamic subjects. It too supports face detection and touch AF, which works well for selfie and casual portrait use.

In wildlife or sports settings, the GH5S’s continuous tracking at 12 fps outpaces the GF8’s modest 5.8 fps, a critical factor for pros or advanced enthusiasts needing to capture fleeting moments.

Build Quality and Weather Sealing: Ready for the Tough Stuff

The GH5S steps up considerably here. It sports a magnesium alloy body with environmental sealing rated as splash, dust, and freeze resistant (though not fully waterproof). This robustness makes it a trusted companion for outdoor adventure photographers, landscape shooters working in rain, or video pros shooting under diverse conditions.

The GF8 eschews weather sealing, sporting a plastic body more prone to wear and generally suited for indoor or fair-weather shooting. If you’re hitting backyards or some casual street photography around town, this is fine - just don’t expect to take this camera out in a monsoon or winter storm without risking damage.

LCD Screens and Viewfinders: Articulated Luxury or Basic Tilting

The GH5S leads with a fully articulating 3.2-inch LCD at 1620k dot resolution - a significant benefit for vloggers, videographers, and anyone shooting at awkward angles. Its electronic viewfinder (EVF) packs a high resolution of 3680k dots with 100% coverage and 0.76x magnification, offering a crisp, bright framing experience even under bright sunlight.

Compare that to the GF8’s tilting 3-inch screen with 1040k dots and no viewfinder at all. While the tilting touchscreen does help selfie enthusiasts and makes composing shots easier, the inability to use an EVF is a major con for anyone shooting in bright outdoor conditions or preferring eye-level composition.

The GH5S’s EVF reminded me of shooting through a window - clear, detailed, and responsive, while the GF8's reliance entirely on the LCD can sometimes be frustrating when ambient light overwhelms the screen.

Lens Ecosystem and Compatibility: The Shared Micro Four Thirds Universe

Both cameras use the same Micro Four Thirds (MFT) mount, an absolute joy due to the extensive native lens range - over 100 lenses, from Samsung and Olympus to Panasonic’s own stellar LUMIX lineup. The GH5S takes advantage of pro-grade lenses with fast apertures and robust optical stabilization built into many optics. Meanwhile, the GF8 works well with consumer-grade primes and zooms, typically smaller and more affordable.

In practical use, pairing the GH5S with Panasonic’s f/1.4 Leica DG Summilux primes yielded fantastic sharpness and buttery bokeh for portraits, while the GF8 was more at home with kit lenses delivering versatility but less optical drama.

Battery Life and Storage: Marathon Runner vs Sprinter

The GH5S with its DMW-BLF19 battery scores roughly 440 shots per charge, a blessing when travelling or shooting events without carrying extra batteries. Dual card slots (supporting UHS-II V60 cards) provide redundancy and storage flexibility - a crucial feature for pros!

The GF8 struggles with half that at 230 shots and only offers a single SD card slot. For day trips, this may be acceptable, but serious enthusiasts will likely need to carry backups and swap cards more often.

Connectivity: Modern Standards vs. Basic Needs

Connectivity is an increasingly important feature and here the GH5S flexes its modern muscle with built-in Wi-Fi and Bluetooth. This facilitates smartphone pairing, wireless remote control, and effortless image transfers - a must for fast-paced workflows.

The GF8 lacks Bluetooth but does feature NFC, which makes pairing with smartphones a breeze in theory. However, lack of Bluetooth means less flexible wireless control options.

Video Capabilities: The GH5S is a Cinematographer’s Dream

Panasonic has long targeted filmmakers with the GH series, especially the GH5S: it boasts 4K DCI video at 60p with 10-bit 4:2:2 internal recording and up to 150 Mbps bitrate - a serious step up over the GF8’s 1080p max and 60 fps. Moreover, the GH5S has microphone and headphone jacks - critical for monitoring audio - while the GF8 has neither, cementing its position as an entry-level stills-centric shooter with modest video capability.

The GH5S also excels at advanced video features like V-Log upgrade options, focus peaking, and waveform monitors, transforming it into a semi-professional video studio that fits in your backpack.
