Olympus E-P3 vs Olympus SP-600 UZ: A Thorough Comparison for the Discerning Photographer

As someone who has spent over 15 years testing an extensive range of digital cameras - from entry-level mirrorless to compact superzooms - I have developed a nuanced understanding of how design choices translate into real-world photographic performance. Today, I’m placing two Olympus models head-to-head that offer very different experiences and appeal to distinct shooter profiles: the Olympus E-P3, an entry-level mirrorless camera launched in 2011, and the older Olympus SP-600 UZ, a compact superzoom from 2010. While both cameras fall under the Olympus banner and sport 12-megapixel sensors, their underlying tech, form factors, and core capabilities diverge sharply.

In this comparison, I’ll leverage my hands-on testing and deep technical knowledge to help you understand which camera suits your photography style, budget, and needs. I’ll cover everything from sensor technology to real-world autofocus and video performance across a broad range of photographic disciplines. Expect candid observations - highlighting both strengths and compromises - backed by authoritative analysis and practical recommendations.

Compact vs. Mirrorless: Size, Handling, and Ergonomics

When choosing a camera, size and ergonomics are often deal-breakers depending on your shooting habits and portability requirements. The Olympus SP-600 UZ is a small-sensor compact superzoom with integrated lens fixed at 28-420 mm equivalent focal length, designed for grab-and-go versatility. The Olympus E-P3, by contrast, is a rangefinder-style mirrorless system camera with interchangeable lenses on a Micro Four Thirds mount.

In terms of physical footprint, the SP-600 UZ is noticeably chunkier and heavier (455 g vs. 369 g) but still compact enough for travel convenience. Its plastic body, while somewhat chunky due to the extensive zoom lens, offers a straightforward grip but lacks some of the refined ergonomics you find on mirrorless cameras. The E-P3 is smaller and sleeker, with a classic retro-inspired design, but its rangefinder styling means it sacrifices a dedicated viewfinder and heftier grip area, which may not be optimal for long lens setups or extended handheld shooting.

Beyond sheer size, the control layout fundamentally affects usability. The E-P3 provides a more traditional camera experience with customizable dials, shooting mode selections, and touch screen controls - while the SP-600 UZ packs a simpler interface aimed at casual shooters.

My testing showed the E-P3’s controls feel crisp and responsive, with the added benefit of touch interface on its 3.0-inch OLED screen (more on that shortly). The SP-600 UZ’s buttons are functional but lack tactile refinement, and some functions require diving through menus, which can slow down shooting opportunities. For photographers valuing quick access to manual settings and tactile control, the E-P3 comes out ahead in ergonomics, despite not having a built-in viewfinder.

Sensor Technology and Image Quality: The Heart of the Camera

Image quality naturally hinges on sensor design and processing power, so I first compared the sensors and output from both models. The E-P3 houses a 12.3 MP Four Thirds CMOS sensor, whereas the SP-600 UZ employs a similarly 12 MP 1/2.3-inch CCD sensor.

This difference in sensor size (about eight times larger area on the E-P3 sensor) is profound. Larger sensor area translates into better light gathering capability, higher dynamic range, improved noise control, and greater depth-of-field control - all invaluable to serious photographers. The E-P3’s sensor measures approximately 17.3x13 mm, enabling a 2.1x focal length crop factor typical of Micro Four Thirds, while the SP-600 UZ’s much smaller 6.08x4.56 mm sensor (crop factor 5.9x) limits its image quality potential.

In practice, my ISO noise performance tests confirmed that the E-P3 maintains clean and useable images up to ISO 1600 at full resolution, with a gradual noise increase beyond that, consistent with a well-optimized CMOS sensor and TruePic VI processor combination. The SP-600 UZ maxes out at ISO 1600 but exhibits significantly more color noise and artifacting at anything above ISO 400.

Color depth and dynamic range benchmarks also favor the E-P3, delivering 20.8 bits of color depth and a dynamic range of 10.1 EV stops according to DxOMark scores, while the SP-600 UZ was not officially tested but generally ranks far lower due to sensor limitations.

This sensor advantage gives the E-P3 a clear edge for demanding photographic scenarios, especially portraits with rich tonal gradations, landscapes requiring dynamic range, and low-light conditions where noise control is crucial.

Viewing and Interface: The Bridge Between You and Your Shot

Electronic viewfinders and LCD screens are integral to composing and reviewing shots. The E-P3 comes with a 3-inch fixed 3:2 OLED touchscreen panel with 614k dots resolution, featuring an anti-fingerprint coating - a fairly sophisticated solution for an entry-level mirrorless.

In contrast, the SP-600 UZ has a smaller (2.7-inch), lower resolution (230k dots) LCD, non-touch, which makes menu navigation and focusing a bit more cumbersome. Neither camera includes a built-in electronic viewfinder, which may hamper precise composition in bright outdoor light, although the E-P3 does support Olympus’s optional external EVF accessory.

During my testing in bright daylight, the E-P3’s OLED screen maintained clarity and color fidelity better than the SP-600 UZ’s LCD. The touchscreen interface on the Olympus mirrorless gave me intuitive control over autofocus points and quick access to settings - a real boost for efficiency. Conversely, the SP-600 UZ’s screen was serviceable but felt dated and less responsive during live view and playback.

Autofocus: Precision vs. Zoom Reach

Autofocus performance can make or break a camera, especially in fast-paced or challenging scenarios like wildlife, sports, or street photography. The E-P3 employs a 35-point contrast-detection autofocus system with face detection and touch AF capabilities. The SP-600 UZ features 143 autofocus points (contrast-detection only) but lacks facial recognition or advanced subject tracking.

From my hands-on experience, the E-P3’s autofocus, although limited to contrast detection, proved reliable and accurate with the touch-to-focus interface on its screen. Face detection worked well for portraits, providing precise eye focus that contributes to flattering skin tone reproduction and sharpness critical for headshots. Tracking moving subjects, however, was modestly challenged under very fast action due to the relatively slow 3 fps burst rate.

The SP-600 UZ’s autofocus was noticeably slower and more prone to hunting in low-contrast or dim environments. Despite its multitude of AF points, it lacks the intelligent algorithms seen in the E-P3. Its 10 fps continuous shooting speed is impressive on paper, but the smaller sensor and simpler AF combat its utility for fast action photography.

In brief: for portraits, street, and moderate wildlife, the E-P3 offers more precise and user-friendly autofocus. If you want extended zoom range at a decent AF speed, the SP-600 UZ is the more suitable option but with compromises on accuracy and low-light responsiveness.

Image Stabilization and Burst Rates

The Olympus E-P3 boasts sensor-based image stabilization - a big advantage for handheld shooting, especially in macro, low light, and telephoto scenarios. The SP-600 UZ, surprisingly, does not have any image stabilization built in, which makes handheld telephoto shots or night photography more challenging.

The continuous shooting capabilities are a tradeoff: the E-P3 shoots at 3 frames per second (fps), modest but sufficient for many amateur applications, whereas the SP-600 UZ claims 10 fps burst shooting. However, the SP-600 UZ’s burst is limited by a slower shutter speed range (max shutter speed 1/2000 vs 1/4000 on E-P3) and the performance benefit is dampened by slow autofocus and smaller buffer.

From my real-world testing, I found the E-P3’s stabilization gave noticeably sharper shots in handheld macro and portrait sessions - a testament to sensor-shift tech Olympus perfected. Meanwhile, the superzoom’s lack of IS requires a tripod or very steady hands once you push the long end of its zoom.

Lens Ecosystem and Flexibility

Perhaps the most significant distinction between the two cameras is their lens approach.

The Olympus E-P3 leverages the Micro Four Thirds mount, opening access to a vast portfolio of over 100 native lenses ranging from ultra-wide-angle primes to telephoto zooms, specialty macros, and premium portrait lenses. This lens ecosystem is a huge asset for photographers wanting creative control and long-term system flexibility.

The SP-600 UZ is a fixed-lens camera with a 28-420 mm (equivalent) zoom range offering impressive versatility out of the box but no room for upgrades or focal length expansion. Its maximum aperture varies between F3.5 and F5.4, which is decent given the focal range but limited for low-light and shallow depth-of-field effects.

For photographers looking to develop a system and explore multiple genres - from landscapes to portraits to street photography - the E-P3’s flexibility is unparalleled within this comparison. The superzoom’s zoom convenience comes at the cost of depth-of-field control and overall optical quality, especially at the telephoto extremes.

Video Capabilities: Moving Pictures Under the Lens

Video shooting is a growing consideration for hybrid photographers and content creators.

The Olympus E-P3 supports Full HD 1080p video at 60 fps in AVCHD and Motion JPEG format, even for smooth slow-motion effects at 720p. Its lack of external microphone input is a limitation, but the presence of an HDMI output allows for clean video out with external recorders.

The SP-600 UZ is restricted to 720p HD video at 24 fps (H.264 encoding), which is suitable for casual use but lacks the frame rate variety and resolution for more advanced needs. No mic input and no image stabilization compound video difficulties on the superzoom.

From my experience, the E-P3 delivers sharper, more detailed, and smoother video footage thanks to its sensor size, processor, and video specs. This makes it a better match for multimedia shooters wanting quality stills and competent video in one package.

Durability, Weather Resistance, and Battery Life

Neither camera features environmental sealing or ruggedized design, so neither is suited for extreme weather without protection. Both offer a built-in popup flash, but the E-P3 also supports external flashes with manual control, which can be invaluable for studio or creative lighting setups.

Battery life favors the E-P3 (approx. 330 shots per charge) using a proprietary lithium-ion pack versus the SP-600 UZ’s unspecified battery stats - a common drawback of compact superzooms where battery drain can be unpredictable. The battery type and life are crucial for travel photographers or extended shooting days.

Connectivity and Storage Options

Both cameras rely on SD/SDHC/SDXC memory cards, which remain the industry standard. On connectivity, the E-P3 has USB 2.0 and HDMI ports but lacks Wi-Fi, Bluetooth, or NFC wireless capabilities, reflecting its age and target segment.

Similarly, the SP-600 UZ offers USB 2.0 and HDMI out with no wireless options. In 2024, these absences are notable, but considering the cameras’ launch dates, it’s not surprising.
