Panasonic S1 vs. Panasonic S5: A Deep Dive into Two Pro Mirrorless Titans

Choosing between the Panasonic Lumix DC-S1 and the Panasonic Lumix DC-S5 feels like picking between two excellent siblings - both born from the same lineage yet crafted for subtly different photographers. After testing both extensively across portrait, landscape, wildlife, and more, I’m here to walk you through their nuances. By the end, you’ll understand which camera truly matches your style, budget, and photographic ambitions.

So, let’s unpack these two full-frame mirrorless cameras - how they perform, where they differ technically, and which comes out ahead in real-world shooting scenarios.

Size, Handling, and Build: Does Size Really Matter?

At first glance, the Panasonic S1 and S5 look like cousins from the same family but with distinct physiques. The S1 offers a robust, SLR-style mirrorless body with a heftier 1021g frame, while the S5 is noticeably lighter and smaller at just 714g.

Handling Experience

Having slipped my hands on both for lengthy sessions, the S1’s bigger grip and sturdier chassis shine in prolonged shooting, especially with larger lenses. If you prefer a camera that feels like a solid extension of your hand, the S1 wins here without question.

The S5’s smaller size and weight, on the other hand, make it a joy for travel or street photographers who value discretion and portability. Carrying the S5 for a full day often felt less fatiguing, especially alongside other gear.

Build Quality

Both cameras feature environmental sealing suitable for dust and light moisture, perfect for outdoor adventures. However, Panasonic’s flagship S1 uses a thicker magnesium alloy shell, which exudes professional-grade durability. The S5, while still well-built, feels more “pro-sumer” in comparison.

I’d recommend the S1’s build for those tackling rugged landscapes or unpredictable weather. The S5 will suffice for most casual outdoor work but with slightly less ruggedness, simply due to its smaller footprint.

A Top-View Comparison: Control Layout and Usability

Operating cameras is as much about button placement and dials as it is about image quality. A quick peek at their top plates reveals some insightful differences.

The S1 impresses with an illuminated top LCD display, invaluable for quick glance settings - especially in bright sunlight. Tough to go back once you’ve experienced it. Meanwhile, the S5 skips that, favoring a streamlined control dial design without extra readouts.

Both cameras house well-placed customizable buttons and dials, but I found the S1’s setup to be slightly more tactile, with illuminated buttons ideal for low-light shooting. The S5 is clean and straightforward, focusing on ease rather than complexity.

If you do a lot of fast-changing settings, shooting in challenging light, or multitasking, the S1’s top panel will be your friend. But for weekend shooters or vloggers wanting simplicity, the S5 is just fine.

Sensor & Image Quality: Peeking Beneath the Hood

Both the S1 and S5 feature a 24MP full-frame CMOS sensor without an anti-aliasing filter, a choice that benefits fine detail retrieval. The sensor dimensions remain identical - 35.6x23.8mm - and provide a generous 847.28 mm² imaging area, powering sharp, high-resolution 6000 x 4000 pixel images.

Image Quality Analysis

In practice, both sensors yield superb image quality with excellent dynamic range - the S1 measured an impressive 14.5 EV on DxOMark, a figure that’s among the best in this category. Although the S5 remains formally untested on DxOMark, early impressions show very similar dynamic range and noise characteristics thanks to sharing the sensor family.

The S1 edges ahead in color depth (25.2 bits) and low-light ISO performance (ISO 3333) according to benchmarks, nudging it slightly ahead for studio, landscape, and event work where subtle tones matter most.

But the difference isn’t night and day. For most real-world shooting, you’ll be hard-pressed to distinguish an S1 shot from an S5, especially when JPEGs or properly exposed RAW files are handled professionally.

ISO Sensitivity & Noise Performance

Both provide native ISO from 100 up to 51200, expandable to ISO 204800 (boosted). When testing my ISO charts and real conditions, the S1 showed marginally cleaner images at higher ISOs, but again, only professionals pixel-peeping will recognize this nuance.

The Backscreen and Viewfinder: How You See Your Shots

A quality screen and viewfinder are critical, especially if you rely on live view or video modes.

The S1 sports a larger 3.2-inch tilting LCD with a sharp 2.1 million dot resolution, while the S5’s 3.0-inch screen offers a fully articulated (vari-angle) design with 1.84 million dots.

Screen Type and Usability

The S5’s fully articulating screen offers more flexibility for vloggers, macro shooters, and anyone shooting at odd angles or selfies - indeed, it is selfie-friendly, unlike the S1. For video creators and content makers, this is a huge advantage.

The S1’s screen tilts but doesn’t flip around, making it less versatile for video-centric applications. However, its higher resolution and slightly bigger display make reviewing photos and LUT adjustments a bit more comfortable.

Viewfinder

Moving to viewfinders - the S1 grabs a clear win here with a 5.76 million-dot OLED EVF with 0.78x magnification, versus the S5’s 2.36 million-dot EVF at 0.74x.

I personally adore the S1’s EVF: it feels large, bright, and immersive, which truly aids in manual focusing and composition confidence. The S5’s EVF is good, just not as striking or sharp.

Autofocus and Shooting Speed: Tracking Your Moments

Autofocus performance is a dealbreaker in wildlife, sports, and event photography. Both cameras employ contrast-detection AF systems coupled with advanced DFD technology but lack phase-detection sensors.

The S1 and S5 sport 225 focus points with face detection but unfortunately no dedicated animal eye autofocus, which some competitors offer.

Speed and Tracking

The S1 shoots up to 9 fps with mechanical shutter, edging out the S5’s 7 fps limit. In burst mode, this advantage could be crucial when capturing fast-moving subjects like birds or athletes.

Regarding tracking accuracy, I found both cameras fairly competent in good light but prone to occasional hunt in more challenging conditions. Neither is best-in-class AF among mirrorless in 2024 but still highly capable for most enthusiast uses.

Video Capabilities: Panasonic’s Hybrid Heritage

Both cameras double as competent video tools, which is unsurprising given Panasonic’s video legacy.

Resolutions and Frame Rates

Both shoot UHD 4K at 60p, with the S5 boasting a higher bitrate (200 Mbps vs. S1’s 150 Mbps). The S5 uniquely supports 6K photo mode, allowing extraction of 18 MP stills from 6K video footage - a nod toward multimedia shooters needing flexibility.

Both cameras record in efficient H.264 and H.265 codecs and support external microphone and headphone jacks for pros.

Stabilization

Both feature 5-axis sensor-based image stabilization that works excellently handheld, smoothing footage and aiding handheld low-light shooting.

Practical Takeaway

If video is a significant consideration, the S5’s feature set nudges it slightly ahead thanks to fully articulating screen, 6K photo, and higher bitrates. The S1 is still outstanding for hybrid photo/video pros but feels a touch less nimble in modern video-centric workflows.

Battery Life and Storage Options

The Panasonic S5 surprises with an impressive 440-shot battery capacity compared to the S1’s 380 shots. In practice, I found the S5 lasted longer on single charges, complemented by slightly smaller size conserving power.

Both include dual card slots, but the S5 supports SD UHS-II cards, ensuring faster write speeds than the S1’s slots. Faster cards can be a boon for burst photographers or 4K video shooters managing large data streams.

Lens Ecosystem and Compatibility

Both cameras mount Leica L-mount lenses, benefitting from the strengths of the L-mount alliance shared between Panasonic, Leica, and Sigma. This association means access to a wide range of over 30 native lenses covering primes, zooms, macros, and specialty optics.

If you intend to grow your kit with premium glass, both cameras have you covered identically. The choice lies more in your preferred lenses than the bodies themselves.

Practical Photography Genres Experience

Let me break down how the S1 and S5 perform across major genres, drawing from my hands-on shoots and client workshops.
