Panasonic FX90 vs. Panasonic GF8: A Hands-On Comparison for Enthusiasts and Pros

When navigating the fast-evolving realm of digital cameras, two models from Panasonic - though separated by five years in release - offer an intriguing study in compact versus mirrorless design philosophies. The Panasonic Lumix DMC-FX90 arrived in 2011 as a small sensor compact, targeting casual users expecting strong portability and ease of use. Meanwhile, the Panasonic Lumix DMC-GF8, launched in early 2016, stakes a claim as an entry-level mirrorless offering, promising larger sensor benefits and interchangeable lens versatility.

With over 15 years of firsthand experience testing cameras across disciplines - from meticulously controlled lab testing to real-world photography expeditions - I’m pleased to dissect these two cameras. What’s their technical and practical performance? How do they serve the varying demands of portraitists, landscape artists, wildlife chasers, and video creators? This detailed, 2500-word comparison unpacks their nuanced capabilities, strengths, and trade-offs through a lens of deep technical insight and honest hands-on appraisal.

Surface Impressions - Size, Weight, and Handling

Picking up the Panasonic FX90 and the GF8 back to back, the difference in body type couldn’t be clearer: the FX90 is a slender, pocketable compact, while the GF8 sports a chunkier, rangefinder-style mirrorless form.

At approximately 102 x 56 x 22 mm and weighing just 149g, the FX90’s compact size paired with a fixed zoom lens (24-120mm equivalent) makes it an ideal street- and travel-friendly choice. In contrast, the GF8, measuring 107 x 65 x 33 mm and weighing 266g, is notably larger and heavier - yet it remains lightweight for a mirrorless device with interchangeable lenses.

Ergonomics favor the GF8 thanks to its more substantial grip and physical control layout; the FX90’s slimness demands more deliberate handling - great for stealth shooting but less ideal for steady grip during extended sessions or telephoto reach.

The top-view layout adds another dimension to usability:

Here, the FX90 maintains a minimalist approach: no dedicated manual exposure dials or buttons, just a cluster for playback, mode, zoom, and basic exposure controls. This simplicity fits casual shooters or quick point-and-shoot scenarios but sacrifices the direct tactile control that more serious photographers crave.

The GF8, conversely, introduces aperture and shutter priority modes and full manual exposure, backed by more physical controls to toggle settings rapidly - a welcome boon for enthusiasts wanting immediate creative input.

Imaging Heart: Sensor Size, Resolution, and Image Quality

Central to a camera’s performance is its sensor - often the difference between snapshots and high-quality photographic expressions.

The FX90 employs a 1/2.3-inch CCD sensor with a 12MP resolution. Sure, this smaller sensor size (about 27.72 mm²) restricts light gathering, especially in dim environments, but it comfortably fits the compact form and fixed lens paradigm. The CCD sensor, though dated by current CMOS standards, produces pleasant image colors with reasonable dynamic range for daylight conditions.

The GF8 steps up with a Four Thirds-sized CMOS sensor measuring 17.3 x 13 mm (224.9 mm²) and delivers 16MP resolution. Compared to the FX90, this sensor is over eight times larger in area, driving massive gains in image quality - especially in noise control, dynamic range, and detail resolution.

In practice, the GF8’s sensor excels in low-light photography with cleaner images at ISO levels unattainable by the FX90. Additionally, the GF8 supports RAW capture, unlocking the full spectrum of post-processing flexibility - a crucial feature for serious photographers, absent on the record-only JPEG FX90.

Autofocus Systems: Speed, Accuracy, and Focus Modes

Autofocus (AF) can make or break your shooting experience, especially with subjects in motion.

Both cameras utilize contrast-detection AF systems, with no hybrid or phase-detection to speed tracking or predictive focus.

The FX90 has 23 focus points and offers touch-based focus selection on its LCD. However, it lacks advanced features such as face or eye detection, and its continuous AF maxes out at 4fps burst shooting - adequate for casual photo bursts but limiting for dynamic subjects.

The GF8 also provides 23 focus points but supplements this with face detection autofocus, improving subject recognition in portraits and group shots. It supports full manual focus, aperture priority, shutter priority, and continuous AF modes, leading to a more versatile focusing experience. Burst rates top out at 5.8fps, slightly faster than FX90.

While neither camera boasts the speed and precision of modern hybrid AF systems found in current flagship mirrorless cameras, in daylight and static subjects, both perform adequately. The GF8’s face detection and manual focus capability notably enhance compositional control.

Shooting Experience Across Photography Genres

Photography enthusiasts and professionals often pursue cameras that perform varied, sometimes contradictory tasks: from vibrant portraits to sprawling landscapes, fast sports, macro close-ups, and sensitive night photography. How do these two stack up field-wise?

Portrait Photography

Portraiture demands natural skin tones, attractive bokeh to separate subjects, and reliable eye or face detection autofocus.

• FX90: The fixed 24-120mm equivalent lens with max aperture F2.5-5.9 offers moderate background separation at the wide end but falls short at telephoto range. No face or eye detection AF makes precise focus on eyes tricky. Still, the lens covers popular portrait focal lengths conveniently for casual snaps.

• GF8: With interchangeable Micro Four Thirds lenses, the GF8 can leverage fast prime lenses (like 25mm f/1.7) delivering creamy bokeh and superior subject isolation. Its face detection AF aids in locking focus on faces quickly. Manual exposure modes empower refined lighting control.

Here, the GF8 clearly appeals to portrait enthusiasts looking for artistic control and shallow depth-of-field effects. FX90 suits casual family portraits when quick usability is paramount.

Landscape Photography

Landscape shooters prioritize high resolution, excellent dynamic range, and robust build for outdoor conditions.

• FX90: Its small sensor limits resolution and dynamic range; the 12MP output is workable for social sharing but not large prints. No weather sealing restricts field use in adverse conditions. The lens’s widest end of 24mm equivalent is sufficient for wide vistas.

• GF8: The superior sensor area coupled with 16MP delivers richer detail and cleaner shadows/highlight retrieval. Tilt screen facilitates composition from ground or awkward angles. However, the lack of weather sealing tempers its use in rugged scenarios, unlike some entry pro cameras.

Overall, the GF8’s image quality suits quality prints and landscape art, although ambitious landscape photographers might seek weather-sealed bodies.

Wildlife and Sports Photography

These genres demand rapid autofocus, high burst speeds, and often telephoto reach.

• FX90: Burst mode locks at 4fps, and AF relies exclusively on contrast detection without subject tracking. Fixed lens zoom tops out at 120mm equivalent - not very telephoto for distant wildlife or fast sports.

• GF8: Burst at 5.8fps plus face detection helps in capturing action, but still no phase detection AF, so tracking very fast or erratic movement is a struggle. However, lens choices include telephoto primes and zooms that can extend reach dramatically.

Neither camera is ideal for serious wildlife or competitive sports photography, where faster autofocus and longer reach - or specialist features like animal eye detection - are game-changers. However, for casual bird watching or recreational sports, the GF8’s versatility and slightly better AF are an advantage.

Street Photography

Lightweight, discreet cameras fare best on the streets.

• The FX90’s compact size and quiet shutter make it excellent for candid shooting. Its touchscreen makes quick setting changes possible, albeit with some delay.

• The GF8, larger but still relatively small for a mirrorless, offers greater creative control but risks drawing more attention. Its tilting screen enables creative vantage points discreetly.

For street shooters valuing portability and unobtrusiveness, the FX90 remains compelling. For those wanting manual control and better image fidelity, the GF8 offers an acceptable compromise in size.

Macro Photography

Both cameras offer macro capabilities:

• FX90: Macro focusing down to 3cm allows close-ups with its optical zoom. Optical image stabilization helps reduce shakes.

• GF8: Macro potential depends on lens choice; a Macro prime or zoom can focus tight. The larger sensor and higher resolution excel in capturing scientific or highly detailed macro images.

Therefore, GF8 paired with dedicated macro lenses easily outperforms the FX90 for macrophotography but at added investment.

Night and Astro Photography

Low-light and astrophotography require good ISO performance and long exposure support.

• FX90: Max ISO 6400 but with smaller sensor and CCD, noise becomes problematic beyond ISO 400-800. No bulb mode.

• GF8: Max ISO 25600 and better noise control thanks to the larger CMOS sensor. Its shutter speeds up to 500s allow night landscapes, though it lacks bulb.

The GF8’s robust ISO performance and longer shutter speed range make it decidedly superior for night and astro applications.

Video Recording Capabilities

Both can capture Full HD, but nuances matter.

• FX90: Offers 1080p at 60/30fps, with optical image stabilization, helping reduce handheld shake. Microphone input is absent; in-built mic quality is average. No 4K recording or advanced video codecs.

• GF8: Also provides Full HD 1080p up to 60fps, but adds richer codec support including H.264. It lacks in-body image stabilization and microphone input as well. Tilting LCD helps compose vlogs or selfies.

Neither model is a powerhouse for professional video, but for casual Full HD recording, they suffice.

Travel and Everyday Use

Battery life hovers around 200 shots for FX90 and 230 for GF8, modest but workable for day trips.

• The FX90’s slim profile and fixed lens make it the quintessential grab-and-go camera.

• The GF8's flexibility with lenses and physical controls make it a better creative travel companion, at some cost in size.

Storage slots support SD/SDHC/SDXC cards equally, and both have built-in Wi-Fi; GF8 has NFC for easier pairing.

Build Quality and Environmental Resistance

Both cameras lack weather sealing, dustproofing, or shock resistance - limiting their use in rough environments. The FX90 is more streamlined, easier to pocket or carry unobtrusively; sometimes, that counts more than ruggedness for casual shooters.

User Interface and Display

Both feature 3-inch screens with touch sensitivity.

The GF8 flaunts a 1040k-dot tilting screen, affording more flexible shooting angles and better visibility than the FX90’s fixed 460k-dot screen. The touchscreen responsiveness is improved on the GF8, contributing to faster and more intuitive menu navigation.

Neither camera has an electronic viewfinder - a notable downside for bright outdoor use where LCD visibility can be tough.

Lens Ecosystem and Upgrade Path

One of the starkest differences: the FX90 has a fixed zoom lens, locking your optical options in.

The GF8, conversely, uses the Micro Four Thirds mount, with access to over 100 native lenses and countless third-party options, from ultra-wide angles to super-telephotos, primes, and classics.

This lens ecosystem versatility is a tremendous advantage, empowering the GF8 to grow with user skills and creative demands.

Connectivity and Storage

Both cameras feature built-in Wi-Fi for wireless image transfer. The GF8’s NFC integration makes connection setup quicker for supported devices.

Storage-wise, each supports SD/SDHC/SDXC cards but only one card slot - common for these consumer-level cameras.

They lack USB 3.0 speeds, limiting large data transfers.

Price-to-Performance: Evaluating Value

At launch and still today, the FX90 retails around $230, while the GF8 costs roughly $550 body-only. This price disparity reflects the GF8’s more recent design, larger sensor, and advanced features.

If budget is the overriding factor and you want a virtually pocketable camera, the FX90 is a cost-effective choice - especially for casual users and street photographers who prioritize simplicity.
