Panasonic Lumix DC-S5 vs. DMC-G7: An Expert Comparison for the Discerning Photographer

In today’s versatile mirrorless camera market, choosing the right tool can feel like walking a photographic tightrope. On one end, we have Panasonic’s Lumix DC-S5, a relatively recent full-frame powerhouse, and on the other, the Lumix DMC-G7, a Micro Four Thirds (MFT) stalwart launched nearly half a decade earlier but still beloved by many enthusiasts. Both cameras wear the Panasonic badge but serve vastly different user needs, budgets, and photographic ambitions.

Having put both through rigorous hands-on testing regimes across an array of shooting disciplines, I’ll guide you through a detailed, side-by-side comparison. This is no shallow spec list: rather, it’s an exploration of how these cameras perform in real-world scenarios, where their technological distinctions matter most.

Physical Build and Ergonomics: Size Matters, But How Much?

First impressions count, and no aspect demonstrates this better than the physical design and handling experience of a camera. The Lumix S5 is a modern full-frame mirrorless with a traditional "SLR-style" heft, while the G7 embraces the classic compactness associated with Micro Four Thirds.

At 714g with dimensions of 133x97x82mm, the S5 weighs almost twice as much as the G7’s 410g (125x86x77mm). The classic Panasonic G7 fits comfortably in smaller hands and is easier to carry all day, ticking the portability box effortlessly for street or travel shooters. However, the S5’s deeper grip and more substantial build allow for a firmer hold, beneficial during prolonged shoots or when using heavier lenses.

The S5’s build is magnesium alloy with weather sealing, offering durability and reassurance outdoors. The G7 lacks environmental sealing, suggesting a focus on indoor or casual shooting environments. Those who work in harsh weather or are prone to travel adventures may find the S5’s build more accommodating.

Ergonomically, the S5 sports larger, well-damped buttons and a layout tuned for professional workflows, while the G7’s controls are smaller but still logically arranged. Overall, the S5 feels like a camera designed for extended use, whereas the G7 embraces lightweight portability.

Control Layout and User Interface: Immediate Access or Moderate Learning Curve?

Looking top-down reveals more about how these cameras interact with users.

The S5 boasts a top panel mode dial with a dedicated exposure compensation dial beside it - features that pros appreciate for swift exposure tweaks without menu diving. Its rear is adorned with a joystick for autofocus point selection, which the G7 lacks, relying more on touchscreen AF area selection.

The G7 retains an exposure compensation dial and a simple mode dial. However, the absence of a joystick means focus area selection can be slower, but the touchscreen somewhat mitigates this.

Neither camera features illuminated buttons, but both include fully articulating 3.0-inch LCDs with touch capability, which we’ll discuss shortly. In terms of control customization, the S5 provides more assignable buttons and dials, enabling photographers to tailor the camera intimately to their style - a boon for professionals or advanced enthusiasts.

Display and Viewfinder: Seeing Your Shot Clearly

Both cameras feature electronic viewfinders (EVFs) with 2.36 million dots resolution and 100% coverage. The S5’s viewfinder magnification stands at 0.74x, slightly larger than the G7’s 0.7x. Practically, this translates to a crisper, more immersive viewfinder experience on the S5 - a subtle detail but one appreciated when composing precise shots.

The rear LCD on both is a fully articulating 3.0-inch touchscreen, critical for video creators and awkward-angles shooting. However, the S5’s LCD sports 1840k dot resolution, compared to the G7’s 1040k dots, rendering a noticeably clearer preview and better confidence in focus assessment.

While the G7’s screen is more than adequate for casual use, the higher pixel density and brightness levels on the S5 are invaluable for professional workflow, especially in bright outdoor conditions. Panasonic’s implementation of touch menus and focus point control is smooth on both, but the S5's more responsive screen feels gratifyingly modern.

Sensor Technology and Image Quality: Full Frame Versus Micro Four Thirds Trade-offs

This is where the cameras diverge most dramatically.

The S5 boasts a 24.2-megapixel full-frame CMOS sensor measuring 35.6x23.8mm, delivering approximately 847 mm² photosensitive area, while the G7 employs a 16-megapixel Four Thirds sensor (17.3x13mm), which is roughly a quarter the size at 225 mm².

In practical terms, the S5’s full-frame sensor offers significantly better low-light performance, dynamic range, and color depth. Panasonic’s sensor omits an optical low-pass filter (anti-aliasing), enabling sharper images straight out of camera, a real plus for landscape and studio photographers chasing detail.

The G7 is no slouch; its sensor produces pleasing images for web and casual prints but shows more noise creeping in at ISO 3200 and beyond. The smaller sensor also translates to a 2.1x crop factor, meaning lenses effectively have narrower fields of view compared to full-frame - sometimes advantageous in wildlife or sports but limiting for wide landscapes.

In my tests, the S5 consistently delivered cleaner files in dim environments and preserved highlight details more gracefully, essential for genres like landscape and portraiture where color fidelity and tonality matter. The G7's files require a bit more noise reduction post-processing when pushing ISO.

Autofocus Systems: Keeping Subjects Pin-sharp

The Lumix S5 employs a contrast-detection autofocus system with 225 focus points, supporting face detection and touch AF - with good tracking capabilities. Despite lacking phase detection AF, its algorithmic sophistication maintains surprisingly effective continuous autofocus in video and stills.

Meanwhile, the G7 offers 49 AF points, also contrast-based, without phase detection or advanced AI tracking features. Both cameras include face detection but stop short of eye or animal eye AF, which are standard now on many competitors.

In real-world performance, the S5's autofocus felt more confident and quicker in low-contrast scenes due to the denser focus points and computational enhancements. The G7 is competent in good light but occasionally hunted under tricky conditions like dim indoor sports or wildlife photography.

Neither camera excels in ultra-fast autofocus tracking for pro sports, but the S5’s broader AF array and better low-light sensitivity provide modest advantages. For portraiture and street scenes, both deliver accurate AF, but the S5 edges out with consistent eye detection and face prioritization.

Burst Shooting and Buffer Depth: Capturing Action

Action photographers will note both cameras offer a maximum 7 frames per second continuous shooting speed. The S5's buffer depth is more generous, supporting longer bursts of high-quality RAW files, which can make a difference during wildlife or sports events.

The G7's buffer is shallower, causing it to pause sooner during sustained burst shooting. Additionally, the S5 offers an electronic shutter speed up to 1/8000s with silent operation, whereas the G7 maxes out at 1/4000s mechanically but can achieve faster 1/16000s electronically.

This difference is relevant for freezing motion in bright conditions or mitigating shutter shock. The S5’s silent shutter can be valuable in settings like weddings or theater, where discretion is paramount.

Video Capabilities: Which Shoots Better Motion?

Both cameras feature 4K video recording, a domain where Panasonic shines.

The S5 can shoot 4K UHD at up to 60p at 200 Mbps in 10-bit 4:2:0 internally, using H.264 or H.265 codecs. It also supports external recording, microphone and headphone jacks, and in-body 5-axis image stabilization - critical for handheld video work.

The G7 delivers 4K UHD up to 30p in 8-bit with lower bitrates, lacks headphone output, and does not have in-body stabilization. Its video codec options include AVCHD, and while sufficient for most casual users, it lacks the pro-level video refinements.

If video is a key priority, the S5's advanced codec support, higher frame rates, and internal stabilization provide a much richer toolset, justifying its higher price for serious hybrid shooters.

Battery Life and Storage: How Long Can You Shoot?

The S5’s battery yields approximately 440 shots per charge, outperforming the G7’s 350 shots. This improvement is not dramatic but noticeable during all-day sessions without frequent battery swaps.

The S5 benefits from dual SD card slots, valuable for backup or overflow, while the G7 offers a single slot. Dual slots are a common feature for pros to safeguard data loss, especially in commercial work.

Both cameras take SD/SDHC/SDXC cards, but the S5 supports faster UHS-II speeds, improving write times for high-bitrate video and rapid burst shooting.

Lens Ecosystem: Leica L-mount Versus Micro Four Thirds

The S5 utilizes the Leica L-mount, a relatively new but rapidly growing mount co-developed by Panasonic, Sigma, and Leica. At launch, about 31 native lenses were available, spanning prime and zoom categories, with high-quality, professional-grade optics geared to leverage the full-frame sensor.

The G7 relies on the Micro Four Thirds mount, which boasts a much larger, mature ecosystem with over 100 lenses from Panasonic, Olympus, and third parties. The smaller sensor allows for cheaper and more compact lenses, an attractive proposition for travelers and street shooters.

Those attached to legacy APS-C or full-frame lenses might find adaptation straightforward on the S5, but the G7’s ecosystem advantage lies in sheer variety and affordability.
