Olympus SP-100 vs Panasonic GF3: A Hands-On Comparison for Photography Enthusiasts

Choosing your next camera is never simple. When faced with two seemingly different but capable bodies - like the Olympus SP-100 bridge camera and the Panasonic Lumix GF3 mirrorless - how do you determine which truly fits your style and needs? Having tested thousands of cameras across the years, I’m here to unpack everything you need to know about these two, from technical details to real-world usability, spanning all major photography genres.

Let’s dive deep, systematically examining design, sensor tech, autofocus, shooting modes, and more, wrapping up with clear recommendations based on your photography ambitions.

First Impressions: Size, Ergonomics, and Build Quality

At first glance, these cameras cater to distinct user philosophies. The Olympus SP-100 straddles the line between a point-and-shoot and DSLR with its SLR-like bridge design, while the Panasonic GF3 offers a compact, rangefinder-style mirrorless form factor.

The SP-100 is noticeably larger and heavier - measuring 122×91×133 mm and tipping the scales at 594g - compared to the GF3’s slim 108×67×32 mm body and 264g weight. That heft, while adding bulk, contributes to a more reassuring grip for those used to more substantial cameras, especially when pairing with a long zoom or heavier lenses.

Both cameras favor a fixed lens solution (SP-100) versus an interchangeable lens mount (GF3), so ergonomics differ importantly based on intended usage. The GF3’s minimalistic, “travel light” feel makes it quite pocketable and discrete - perfect for street photography or casual outings. The SP-100, equipped with a giant 24-1200mm zoom (50×), is better suited for those wanting long reach without lens swaps.

Build quality on both is average for their class; neither offers weather sealing - so if you shoot landscapes in inclement weather or rugged wildlife sessions, keep that in mind.

A quick peek at their control layouts highlights difference in shooting approach:

The SP-100’s traditional dial and numerous buttons provide quicker manual control access, a boon when capturing fast-moving subjects - a nod to its semi-pro shooters. In contrast, the GF3 relies more on touchscreen and simplified controls, reflecting its entry-level positioning.

Sensor Size and Image Quality: The Heart of the Matter

Sensor size directly impacts image quality, depth of field control, and low-light capability. Here, the Panasonic GF3’s Four Thirds sensor dwarfs the tiny 1/2.3-inch sensor inside the Olympus SP-100.

This difference - 224.9 mm² vs 28.07 mm² - is substantial. The GF3’s sensor, measuring 17.3×13 mm, boasts a native 12MP resolution (4000×3000), while the SP-100 squeezes 16MP into a 6.17×4.55 mm sensor. The smaller sensor constrains dynamic range and low light performance for the Olympus.

In practical tests, the GF3 produces sharper, less noisy images at high ISO (up to ISO 6400 native) thanks to its larger photosites and superior signal-to-noise ratio. The SP-100 does well in bright daylight but struggles with high-ISO noise and compressed dynamic range in shadows and highlights.

Interestingly, the SP-100’s sensor benefits from back-illuminated CMOS design, which improves light gathering relative to older tech, but the gap in sensor area retains dominance.

Views and Displays: Frame Your Shot with Confidence

Both cameras feature 3-inch 460K-dot fixed LCDs; however, their implementation and viewer aids differ.

The SP-100 includes a high-resolution electronic viewfinder (920K dots), allowing precise composition in bright sunlight and steady handheld framing during long zoom shots - a clear benefit outdoors and for telephoto work.

The GF3, lacking any viewfinder, relies entirely on the rear LCD, which is touch-sensitive. This touchscreen integration offers intuitive focusing and menu navigation, speeding up operation for novices or casual shooters but at a cost of visibility challenges under strong ambient light.

For video enthusiasts, the SP-100’s viewfinder and stable grip offer more assured shooting, especially during long clips in daylight.

Autofocus Systems: Accuracy and Speed in Real Use

Both cameras use contrast-detection autofocus, typical for their classes, but their performance varies.

The GF3 employs 23 AF points with face detection, providing more precise subject tracking and focus on complex compositions. While no phase-detection AF is present, autofocus is snappy and reliable indoors and outdoors.

The SP-100, despite an unknown number of focus points, offers face detection and continuous AF modes, plus the advantage of manual focus assist through focus peaking and a manual focus ring. However, its AF speed is generally slower, particularly noticeable when zoomed past 600mm-equivalent.

In action photography like wildlife and sports, the GF3’s smoother continuous AF and faster shutter speeds (up to 1/4000 sec) give it an edge, though rapid burst shooting is limited to just 3 FPS compared to the SP-100’s 7 FPS.

Lens Ecosystem: Fixed Versus Interchangeable

The choice here boils down to whether you prefer a versatile all-in-one zoom or the freedom to swap lenses.

The Olympus SP-100 comes with an impressive 24-1200 mm (equivalent) zoom range, covering ultra-wide to super-telephoto without changing lenses. This is magical for wildlife or sports where lens swapping is impractical. Still, the max aperture narrows to f/6.5 at telephoto lengths, limiting shallow depth of field and low light capabilities.

Conversely, the Panasonic GF3’s Micro Four Thirds mount unlocks a vast lens library - over 100 lenses from Panasonic, Olympus, and third-party makers - covering everything from ultra-fast primes for portraits to macro and ultra-wide angles. This adaptability makes it ideal for those wanting to tailor gear per project or genre. The tradeoff is the need to carry multiple lenses and swap physically.

Battery Life and Storage: Staying Powered and Ready

Battery endurance is similar: 330 shots per charge for the SP-100 using the LI-92B pack versus approximately 300 shots for the GF3, though in my long shooting sessions, the SP-100’s higher power demands at zoom and video nudged battery life lower than rated.

Both cameras use SD/SDHC/SDXC storage cards in a single slot, with the GF3 supporting UHS-I speeds for faster write performance. Neither support dual card slots or in-camera raw file processing, but the GF3 supports RAW capture itself, a crucial advantage.

Video Capabilities: Capturing Motion with Confidence

Both cameras record Full HD video with 1080p resolution.

Olympus SP-100 shoots in H.264 format up to 60p, offering smooth motion capture and a microphone port - an essential for external audio upgrade. Stabilization helps reduce handheld shake, especially useful during telephoto zoom clips.

The Panasonic GF3 also records 1080p at 60p but in AVCHD and Motion JPEG, lacking a microphone jack and in-body stabilization. However, many MFT lenses include optical stabilization to compensate.

While both cameras’ video modes suit casual use, the SP-100’s longer zoom and stabilization edge it closer to versatile video capture.

Making It Work for Portraits and Skin Tones

Portrait photographers benefit from natural skin tones, pleasing bokeh, and eye detection.

The GF3’s larger sensor and interchangeable fast lenses provide beautiful background blur and shallow depth of field control, critical for compelling portraiture. The 12MP sensor’s cooler color rendition captures warm, accurate skin textures with subtle tonal gradations.

The SP-100’s small sensor keeps much of the scene in focus, sacrificing creamy bokeh, especially at long zoom ranges where aperture narrows. Skin tones remain acceptable but slightly less nuanced.

Both cameras offer face detection autofocus, helpful when shooting people, but the GF3’s AF system more consistently locks onto eyes or faces with precision.

Landscape and Nature: Dynamic Range and Resolution

Landscape shooters need fine detail, extensive dynamic range, and weather durability.

The GF3’s Four Thirds sensor delivers cleaner shadows and preserved highlight detail, largely due to its larger pixel area and higher dynamic range measured at 10.1 EV (per DXO Mark). Its 12MP resolution yields sharp files for modest prints and cropping flexibility.

The SP-100, lacking raw capture and with less dynamic range (not DXO tested but inferably lower), captures scenes less forgivingly; shadows may block up, and highlights clip earlier.

Neither camera features environmental sealing, so protecting gear outdoors remains necessary.

Wildlife and Sports: Speed, Tracking, and Reach

Sports and wildlife photographers prioritize autofocus speed, frame rates, and focal reach.

The SP-100’s 50× zoom lens is immediately advantageous, letting you get physically closer without disturbing animals or athletes. Its 7 FPS burst rate surpasses the GF3’s measly 3 FPS, too.

However, the GF3’s autofocus tracking is smoother, beneficial for unpredictable motion. Plus, with interchangeable super-tele lenses, you can push even further, given bigger investment.

In low light sports arenas, the GF3’s sensor shines with better high ISO noise control, enabling sharper results without excessive grain.

Street and Travel Photography: Discreteness and Portability

For street shooters, subtlety and agility matter.

The GF3’s compact size and near-silent operation make it an unobtrusive companion - the ideal grab-and-go camera for candid moments. Touchscreen controls speed framing and exposure adjustments, while its varied lens choices offer flexibility for any focal length.

The SP-100’s bulk and long zoom make it less discreet; however, its all-in-one design and better zoom reach bring value when you want to travel light with telephoto reach.

Battery life and weight also favor the GF3, making it a trusty travel mate.

Macro and Close-up Work: Getting Precise

Olympus claims a macro focus range down to 1 cm, which theoretically lets you get very close. Given its fixed lens, close-up shooting is relatively straightforward with decent stabilization.

The GF3’s macro prowess depends heavily on lens choice - as many MFT lenses focus closer than 30 cm with sharp results and offer manual focus assists like focus peaking, which I appreciate for critical detail work.

Lack of in-body stabilization on the GF3 pushes macro shooters to rely on tripod or stabilized lenses.

Night / Astrophotography: Low Light and Exposure Control

Night photography demands high ISO performance, long exposure flexibility, and low noise.

The Olympus SP-100 supports shutter speeds up to 1700 seconds, a huge plus for star trail or long exposure cityscapes. Its Optical Image Stabilization assists handheld low-light shooting but doesn’t compensate for extreme exposure needs.

The GF3 maxes out at 60 seconds shutter speed, limiting some long exposure opportunities unless a bulb mode is present (not officially listed). However, cleaner high ISO results (low-light ISO score 459 vs. untested SP-100) favor it for night street photography.

Both offer manual exposure modes and white balance adjustment to fine-tune results.

Professional Use and Workflow Integration

Neither camera is built for high-end professional studio use or demanding workflows.

The GF3’s RAW support eases post-processing, letting professionals squeeze maximum image quality. Its Micro Four Thirds mount opens doors to pro-grade lenses, supporting diverse work.

The SP-100’s lack of RAW limits flexibility; reliance on JPEG straight from the sensor may frustrate advanced editors.

Connectivity options are basic for both - no Wi-Fi or Bluetooth - which might hinder remote work, but both include USB 2.0 and HDMI for data transfer and external monitor use.
