Olympus SP-810 UZ vs. Panasonic Lumix DMC-GF3: A Hands-On Comparison for Enthusiasts and Pros in 2024

Choosing the right camera in the entry-level to enthusiast segment can be daunting, especially when faced with two very different systems like the Olympus SP-810 UZ and the Panasonic Lumix GF3. Announced in mid-2011, these cameras represent distinct design philosophies and user experiences. The Olympus SP-810 UZ is a bridge-style superzoom with a fixed lens and long focal reach, while the Panasonic GF3 is an early but highly relevant mirrorless Micro Four Thirds system camera with interchangeable lenses.

Having spent considerable time with both models in varied shooting scenarios and scrutinizing their specifications and capabilities, I’m ready to unpack exactly where each shines, who they suit best, and how they stack up in crucial real-world photography disciplines and technical criteria. While both cameras are now considered dated in 2024, their distinct designs still hold lessons and opportunities for photographers intentionally seeking a lightweight superzoom or an affordable interchangeable lens mirrorless system.

Let’s dive in.

Holding Them in Your Hands: Size, Ergonomics, and Controls

Your first tactile impression strongly influences whether a camera feels like an extension of your creative vision - or just a frustrating tool. The Olympus SP-810 UZ, built like a bulky bridge camera, is SLR-like in appearance and relatively chunky. It measures 106x76x74mm and weighs about 413 grams. In contrast, the Panasonic GF3 embodies the minimalist rangefinder mirrorless ethos: compact, flat, and lightweight at 108x67x32mm and 264 grams.

The SP-810’s grip is generous with a deep front thumb recess and textured rubber, lending stability especially when zoomed out near its impressive 36x reach. However, I found its thick body less pocketable and a bit tiring for day-long handheld use. The GF3, conversely, feels like a discrete street shooter’s ideal companion - slim, pocketable (with pancake lenses), and extremely portable.

Looking at the top control layouts in close detail:

Olympus offers a simplified layout - no manual exposure dials, shutter speed, or aperture control. All adjustments happen through a mode dial with limited exposure modes, catering to a more casual user who might prioritize zoom versatility over granular control.

Panasonic’s GF3 takes the enthusiast route, giving manual exposure modes, aperture priority, shutter priority, and access to more settings through dedicated buttons and a touchscreen interface. This flexibility translates to greater creative command - something I always appreciate when shooting advanced compositions.

Regarding their LCD screens:

The GF3’s 3-inch, 460k-dot touchscreen offers vibrant colors and crisp detail. Touch-to-focus and touch-shutter add intuitive operation, reducing menu dives and making it a pleasure to compose, especially when eye-level framing is unavailable.

The SP-810’s 3-inch, 230k-dot screen feels less crisp and lacks any touch sensitivity, making navigation slower and less enjoyable. Also, neither camera includes an electronic viewfinder (EVF), leaving live LCD framing as your sole composition method.

Sensor Technologies, Image Quality & ISO Performance

Image quality remains the beating heart of a camera’s worth. The Olympus SP-810 UZ employs a small 1/2.3-inch CCD sensor measuring approximately 6.17 x 4.55 mm, delivering 14MP resolution. Meanwhile, the Panasonic GF3 boasts a Four Thirds CMOS sensor measuring significantly larger at 17.3 x 13 mm with 12MP resolution. Size matters here - more sensor real estate typically means better dynamic range and low-light performance.

I rely heavily on DxOMark-style empirical analysis and controlled studio testing to assess image quality factors like color depth, dynamic range, and low-light ISO performance. Unfortunately, the SP-810 UZ was never formally tested by DxOMark, but the sensor size and CCD tech hint at limitations. The GF3’s sensor scores 50 overall - impressive for an entry-level mirrorless camera of its era - with a color depth of 20.6 bits, dynamic range of 10.1 EVs, and usable ISO up to 459 for low-light situations.

In practical terms, the GF3 wins hands down where image quality is concerned. Its larger sensor generates cleaner images with better detail retention, particularly in shadows and highlights. The difference in low-light sensitivity was stark in my nighttime shooting tests, with the SP-810’s images showing more noise and washed-out colors above ISO 400, while the GF3 kept noise at bay up to ISO 1600.

Autofocus, Burst, and Responsiveness: Action-Ready or Not?

These cameras serve very different shooting styles, so let’s look at their ability to follow fast-moving subjects - critical for wildlife, sports, and street photography.

The Olympus SP-810 UZ’s autofocus system is contrast-detection only, with face detection and some tracking capabilities, but no phase-detection autofocus. It features a modest continuous shooting speed of 0.7 fps - attempting fast action results in missed moments and focus hunting.

The Panasonic GF3, on the other hand, offers contrast-detection with an improved multi-area autofocus system, 23 focus points, and face detection. It shoots at 3 fps continuous burst, offering better chances to capture fleeting moments in sports or street photography. While slow by today’s standards, in 2011 this was competitive for an entry-level mirrorless.

I found the GF3 more reliable in locking focus on moving subjects, especially in decent light. The lack of phase detection is still a downside, causing lag under low light or erratic movement, but overall it beats the Olympus for AF speed and accuracy.

Zoom Range and Lens Compatibility: Versatility vs. Image Quality?

One of the most obvious differences is Olympus’s SP-810 UZ fixed superzoom lens that covers an extraordinary 24-864mm equivalent focal range - a staggering 36x zoom. This immense reach makes it a trojan horse for travel photographers and wildlife hobbyists who want one lens that covers it all.

Conversely, the Panasonic GF3 offers no fixed zoom lens - it’s a Micro Four Thirds mount system with 107 native lenses available ranging from ultra-fast primes to versatile zooms. The 2.1x crop factor means you select a lens matching your task. Want long reach? Mount a 100-300mm tele zoom. Need sharp wide angles? Choose a 20mm f/1.7 pancake. The GF3’s ecosystem flexibility is a key advantage in professionalism and creative variety.

During testing, I used the GF3 with a 14-42mm kit lens (28-84mm equiv.) and a 45-150mm tele zoom (90-300mm equiv.). The lens quality overall outclasses the SP-810’s fixed zoom in terms of sharpness and controlling optical aberrations. The Olympus lens suffers some softness and distortion at extreme telephoto - expected at 36x zoom.

Portraiture: Skin Tones, Bokeh, and Eye Detection

Portrait shots reveal a camera’s color science and its ability to isolate subjects beautifully.

The GF3’s larger sensor combined with lens options featuring wider apertures (like f/1.7 primes) offers superb shallow depth of field effects and natural creamy bokeh. Skin tones render realistically and smoothly, though some slight softness from the 12MP resolution compared to modern full frames is noticeable at 100% crop.

The SP-810’s smaller sensor struggles to produce truly blurred backgrounds. Its maximum aperture of f/2.9 at wide angle closes to f/5.7 at telephoto, and small sensor size means more depth of field - backgrounds often appear busier. However, Olympus’s face detection AF works well for keeping portraits sharp though eye detection is absent on both cameras.

If portraits are a priority, I recommend the GF3 paired with a fast prime lens.

Landscapes: Dynamic Range, Resolution, and Durability

The bigger sensor and RAW support of the GF3 encourage serious landscape photographers. With its 12MP Four Thirds sensor, it delivers good detail and 10+ stops dynamic range, which combined with bracketing modes, offers greater editing latitude to pull shadows and control highlights.

The SP-810 outputs JPEGs only (no RAW), limiting post-processing flexibility. The small sensor means lower dynamic range and more noise when pushing exposure. Also, the build quality is plastic and not weather sealed on either camera, so neither is ideal for heavy outdoor use in harsh environments.

However, the SP-810’s zoom versatility lets you capture distant mountain peaks or wildlife without switching gear - a plus for landscape hikers who want one all-in-one solution without carrying multiple lenses.

Wildlife and Sports: Autofocus Speed and Burst Rates

Wildlife photographers tend to prioritize fast burst rates, reliable autofocus tracking, and long telephoto reach.

The SP-810 provides massive 864mm equivalent reach (ideal for distant animals) but falters with sluggish AF and 0.7 fps burst. This limits capturing critical moments like birds in flight or fast mammals.

The GF3, with its interchangeable telephoto lenses and 3 fps burst, has a more dependable focus system with better continuous AF functionality. While its reach tops out shorter than the SP-810’s max zoom unless you invest in longer MFT lenses (which add cost and bulk), it nonetheless offers higher image quality and better action tracking.

Street Photography and Portability

Street photographers prize discretion, speed, and unobtrusiveness. Here, the GF3 markedly outperforms the Olympus.

Its slim, rangefinder-style design and small prime lenses make it less intimidating in social settings. Touchscreen focus aids rapid compositions and candid shots. The SP-810’s bulk and long zoom shout “tourist” - not covert camerawork.

Low-light street environments favor sensors with higher ISO tolerance - the GF3’s CMOS sensor clearly has the edge over the SP-810’s CCD.

Macro Photography: Close Focus and Stabilization

Close-up photography requires strong macro capabilities and focus accuracy.

The Olympus offers a 5cm macro focus range, combined with sensor-shift stabilization, which helps handholding shots at very close distances. Its built-in stabilization enhances sharpness in macro shooting.

The Panasonic GF3 lacks in-body stabilization but benefits from optical stabilization available in some lenses (depending on your lens choice). Manual focus and focus peaking (if supported by third-party firmware) aid precision here.

Night and Astrophotography

Night and astro shooters examine ISO performance, exposure control, and noise handling.

The GF3’s CMOS sensor with better high ISO performance allows shooting at ISO up to 3200-6400 with manageable noise in some cases. It supports full manual exposure settings, crucial for long exposures under stars.

The SP-810 maxes out at ISO 3200, but noise rises rapidly above ISO 400 due to the small sensor and CCD tech. Long exposure times up to 20 seconds are possible but results are noisier.

Video Capabilities

Video often matters even to still shooters.

The GF3 captures Full HD 1920x1080 at 60fps in AVCHD and Motion JPEG formats - competent and fluid footage for its time, with smoother autofocus transitions.

The SP-810 tops out at 1280x720 at 30fps MPEG-4 videos - adequate but behind the GF3’s capabilities.

Neither camera offers microphone or headphone ports, limiting professional audio control.

Travel and Everyday Use

Travel photography demands lightweight, versatile gear with long battery life.

The GF3’s weight and compact design make it ideal for travel, especially when paired with pancake primes. Battery life rated at 300 shots is modest but acceptable in this class.

The SP-810’s larger size and weight make all-day carry more tiring, but the extensive zoom range means fewer lens swaps and less gear juggling.

Professional Use and Workflow Integration

While neither camera targets the professional market, the Panasonic GF3 is a clear frontrunner for pros seeking a backup or compact system.

It supports RAW files, exposure bracketing, and more advanced exposure modes, fitting better into post-production workflows.

The Olympus’s lack of RAW capture and limited manual controls restrict its utility in professional settings.

Storage, Connectivity, and Reliability

Both cameras use SD/SDHC/SDXC cards (single-slot), standard in this segment.

Neither offers wireless connectivity or GPS - normal for their generation but now dated.

Battery technology in both relies on proprietary Li-ion packs, with reasonable endurance.

Neither camera features weather sealing or ruggedized construction, so care is needed outdoors.
