Panasonic G95 vs Sigma fp: The Battle of Advanced Mirrorless Cameras in 2024

I have put both the Panasonic Lumix DMC-G95 and the Sigma fp through their paces over weeks of shooting in diverse scenarios - from bustling city streets to serene landscapes, fast-paced sports events, and delicate macro subjects. These two mirrorless cameras, though both cutting-edge for their time in 2019, come from very different design philosophies and target audiences. In this detailed comparison, I’ll walk you through how they stack up across all major photography types and technical parameters, peppered with insights from my hands-on testing that only come from years of camera evaluation.

I do not have official affiliations or sponsorships with either brand, so this review is built on transparency and real-world experience. Whether you are a portrait photographer, wildlife shooter, videographer, or a hybrid enthusiast, by the end you’ll have a clear sense of which camera (if either) suits your style and budget.

Size, Ergonomics, and Handling: When Size Really Does Matter

Starting with how these cameras feel in the hand - you’ll find the Panasonic G95 follows the traditional SLR-style mirrorless design with a robust, somewhat chunky body, while the Sigma fp takes a strikingly minimalistic, rangefinder-style approach. This difference isn’t superficial: it shapes the entire shooting experience.

The Panasonic G95 measures approximately 130x94x77mm and weighs 536 grams with battery, offering a substantial grip and reassuring feel during handheld work. Its body is weather-sealed, providing solid durability against dust and moisture - essential for outdoor photographers who shoot in less-than-ideal conditions regularly.

By contrast, the Sigma fp is a slender beauty at just 113x70x45mm and 422 grams. It’s arguably the most compact full-frame mirrorless camera I've tested, and its lightweight nature invites you to carry it almost anywhere without fatigue. However, the minimal body means fewer physical controls - an intentional choice by Sigma but a compromise with usability for some workflows.

Top View and Control Layout: Intuition Meets Minimalism

Digging into the user interface side-by-side reveals where Panasonic leans into accessibility and Sigma embraces minimalism.

The G95’s top plate is busy by design: dedicated dials for shutter speed, exposure compensation, and drive modes, plus a top LCD panel to quickly verify settings. Tactile buttons with good spacing help you adjust exposure quickly without digging into menus - a helpful trait for sports and street shooters needing speed and confidence.

The Sigma fp removes all that complexity, resulting in a top plate with just the essentials. There are no dials for shutter speed or ISO; those settings demand menu diving or touchscreen use. This can feel liberating or frustrating depending on your preference. For studio photographers or those who like to experiment with slower-paced shooting, the fp’s approach works well. But for run-and-gun street or wildlife photographers, the slower control access can be a drag.

Sensor and Image Quality: Micro Four Thirds Meets Full Frame

Sensor size often dictates image capabilities more than any other factor. The Panasonic G95 uses a Four Thirds-sized CMOS sensor measuring 17.3 x 13mm, sporting a resolution of 20.3 megapixels. The Sigma fp features a significantly larger full-frame BSI-CMOS sensor at 35.9 x 23.9mm with 25 megapixels, which intrinsically sets a different tonal and depth rendering baseline.

In my experience, the G95’s Micro Four Thirds sensor provides excellent detail for landscapes and general photography, especially when paired with the excellent OIS-enabled lenses in the Micro Four Thirds ecosystem. The smaller sensor also means lenses tend to be smaller and lighter - a helpful factor for travel and handheld shooting.

However, the Sigma fp’s full-frame sensor offers superior noise control at high ISO and delivers that coveted shallow depth-of-field aesthetic impossible on a smaller sensor. The 25MP resolution strikes a balance, providing plenty of detail without overwhelming file sizes.

For image quality purists, the larger sensor combined with Sigma’s unique color science translates to raw files with a rich tonal range and excellent highlight recovery. Despite lacking in-body stabilization, the fp’s sensor gives benefits in image quality that are noticeable in low light and portrait situations.

LCD Screens and Electronic Viewfinders: See Your World Clearly

Practical usability means reliable displays and framing aids.

The Panasonic G95 sports a 3-inch fully articulated touchscreen with a modest resolution of 1.24 million dots. The articulation is a standout feature for videographers, vloggers, and macro shooters who often need flexible angles. Its electronic viewfinder (EVF) offers decent 2.36-million-dot resolution with near 100% coverage and a 0.74x magnification, delivering a bright and accurate composing experience in varied lighting.

Sigma fp foregoes any built-in viewfinder entirely. Instead, it relies solely on a fixed 3.2-inch touchscreen with slightly higher resolution at 2.1 million dots. The larger screen is sharp and responsive but having no EVF is a dealbreaker in bright outdoor conditions, street photography, or moments demanding stability and eye-level framing.

In practice, I found the fp’s screen excellent for studio work or tripod-based shooting but struggled under direct sun in the field. The Panasonic’s EVF remains the faster, more ergonomic choice for immersive shooting.

Autofocus Systems: Speed and Accuracy on Assignment

Both cameras use contrast-detection autofocus without phase-detection pixels - an important technical note that impacts speed and tracking.

With 49 focus points each, both offer face detection and continuous AF modes, but neither supports animal eye AF, which is uncommon at this level but notable for wildlife photographers.

In real-world tests, the G95’s autofocus is swift and reliable in good lighting, locking quickly onto human eyes and maintaining smooth tracking in continuous mode. The Panasonic’s AF algorithms are mature, especially notable in portrait and video modes where eye detection aids precise focusing.

The Sigma fp’s autofocus, while competent for static subjects, was more sluggish and prone to hunting under lower light or fast action. For wildlife or sports photographers requiring rapid and accurate AF, the fp may feel a step behind compared to Panasonic’s optimized system.

Burst Shooting and Shutter Performance: Freeze the Moment

Frame rates often influence decisions for sports, wildlife, and event shooters.

• Panasonic G95: Up to 9 frames per second (fps) with mechanical shutter; 1/16000s max electronic shutter.
• Sigma fp: Up to 12 fps mechanical shutter; max shutter speed of 1/8000s.

The Sigma fp’s faster burst mode may appeal to action shooters, but Panasonic’s superior electronic shutter speed offers completely silent shooting at up to 1/16000s - perfect for discreet street photography or sensitive wildlife situations. The G95's shutter also produced less distortion with fast-moving subjects during my tests.

Video Capabilities: Professional Video Meets Experimental Cinema

Videographers will find interesting contrasts here.

The Panasonic G95 shoots 4K UHD video up to 30p at 100 Mbps in MP4 and AVCHD formats, with impressive in-body 5-axis image stabilization supporting handheld 4K. It also features mic and headphone ports for pro audio monitoring. It excels in hybrid shooting where both stills and video are critical, with post-focus and focus stacking tools available.

The Sigma fp, billed as "the smallest and lightest" full-frame cinema camera, records 4K UHD at 30p (MOV, H.264) with linear PCM audio. Despite lacking image stabilization, its uncompressed open-file capabilities in Cine-DP RAW (via external recorder) have made it a darling for indie filmmakers. The cage-style modular design enables custom rig setups, but out of the box, video requires more accessories to unleash full potential.

Build Quality and Weather Resistance: Rugged Travel Allies

Both cameras have environmental sealing but are not fully waterproof or frost-rated.

The Panasonic G95’s build felt more durable in my field work, with weather sealing protecting me from dust and light rain during hikes and coastal shoots. Its larger grip and shutter button placement contribute to better stability in adverse weather.

The Sigma fp’s compactness comes with trade-offs: its minimal weather sealing is adequate but less reassuring in humid or dusty conditions. The reduced heft and grip require extra care when shooting handheld in challenging environments.

Lens Ecosystem and Compatibility: The Footprint of Your Glass

Lens availability can make or break your system choice.

Panasonic’s familiar Micro Four Thirds mount enjoys a flourishing ecosystem with over 107 native lenses from Panasonic, Olympus, and third parties. This variety means lenses ranging from ultra-wide to super telephoto, macro, and affordable primes, many with optical stabilization to complement the sensor.

Sigma’s L-mount is compatible with around 30 native lenses - fewer, but growing. The mount benefits from cooperation with Leica and Panasonic (L-mount alliance), widening options including Leica’s excellent glass. However, many lenses are pricey and tend to be larger, matching the full-frame optical demands.

If lens choice and diversity are paramount to your workflow, Panasonic’s mature system gives a clear advantage.

Battery Life and Storage: Keep Shooting Longer

Battery life is a practical concern, especially when traveling or shooting long sessions.

The Panasonic G95’s battery rated for approximately 290 shots per charge, which aligns with typical Micro Four Thirds mirrorless cameras. It uses standard SD cards (UHS-II compatible) with a single slot.

The Sigma fp has an underwhelming battery life by comparison, primarily due to the demanding full-frame sensor and smaller battery capacity. Exact CIPA ratings were unavailable, but real-world shooting suggests fewer than 200 shots per charge, necessitating spare batteries for all-day usage.

Storage-wise, the fp supports UHS-II SD cards in a single slot as well. Both cameras lack dual card slots, which may matter for professional workflows requiring immediate backups.

Connectivity and Wireless Features: Modern Sharing and Control

The Panasonic G95 includes built-in Wi-Fi and Bluetooth for remote control and image transfer via smartphones. These tools are mature and user-friendly.

In stark contrast, the Sigma fp does not offer any wireless connectivity options, limiting on-the-go sharing and wireless tethering - a drawback for fast-paced professional shoots or social media enthusiasts.

Price and Value: What Are You Really Paying For?

At launch and current market pricing:

• Panasonic Lumix G95: Approximately $1,000
