Olympus E-400 vs. Olympus Stylus SP-820UZ: A Hands-On Comparison for the Budget-Conscious Photographer

When navigating the often cluttered world of digital cameras, making the right choice - especially on a budget - can feel like wandering a photographic jungle without a compass. Today, I’m taking a deep dive into two very different Olympus offerings that might appeal to you if you’re after an affordable camera with respectable chops: the venerable Olympus E-400 entry-level DSLR, announced in 2006, and the quirky, long-zoom Olympus Stylus SP-820UZ, a small sensor superzoom from 2012.

These cameras serve very different purposes, yet they often appear side-by-side in bargain bins or online marketplaces, and it’s important to understand how they measure up technically and practically. I’ve tested and dissected both in various real-world scenarios - from portraiture to wildlife, landscapes to street photography - to help you figure out which fits your creative ambitions and wallet best.

Let’s start by putting these two cameras side-by-side - physically and functionally.

Size, Feel, and Handling: DSLR vs. Superzoom Compact

The Olympus E-400, despite its “compact SLR” nomenclature, is relatively small for a DSLR of its era. Its dimensions (130x91x53 mm) make it less bulky than many entry-level DSLRs today, and it weighs in at 435 grams. The E-400 features a traditional DSLR body, complete with an optical pentamirror viewfinder and a lens mount supporting interchangeable Micro Four Thirds lenses.

In contrast, the SP-820UZ is a pocket-friendly superzoom, with a smaller 1/2.3" sensor but a gigantic zoom range crammed into its compact CAM-style chassis (117x78x93 mm, 485 grams). Unlike the E-400, it has a fixed lens - a 40x optical zoom covering 22-896 mm equivalent - which greatly expands its versatility for distant subjects, albeit with the usual trade-offs in image quality inherent to small sensors.

Ergonomically, the E-400 gives you more traditional clubs for your thumbs and fingers, with manual controls better suited for those taking photography seriously and gradually learning manual exposure. The SP-820UZ leans toward ease of use and portability, more of a grab-and-go camera. Neither offers weather sealing or ruggedized durability, so both are best kept out of harsh environments.

The E-400’s top plate features a classic control layout with dedicated dials for shutter/aperture priority modes; meanwhile, the SP-820UZ minimizes physical buttons in favor of an all-auto or simple modes operation, with only basic exposure options.

Sensor Technology and Image Quality: The Heart of the Matter

Image quality is arguably the make-or-break factor for any photography enthusiast, and here these two cameras diverge sharply.

The Olympus E-400 is armed with a Four Thirds CCD sensor measuring approximately 17.3 x 13 mm (224.9 mm²), offering a native resolution of 10 megapixels. With its larger sensor size (compared to typical compacts), it naturally gathers more light, resulting in better low-light performance, richer colors, and generally more natural skin tones for portraits. The sensor sticks to a 4:3 aspect ratio, which can be more accommodating for certain types of composition, especially landscapes.

The Stylus SP-820UZ’s sensor is a typical small-sensor compact at 1/2.3" size (6.17 x 4.55 mm, approx. 28 mm²), with a higher pixel density at 14 megapixels. This leads to a higher risk of noise and detail loss, especially when pushing beyond ISO 400–800. While the ISP and lens optics help somewhat, you won’t get the same dynamic range or depth of field control as you do from the E-400’s bigger sensor.

From my lab testing with standardized color charts, the E-400 delivers smoother gradations, better dynamic range (useful for sunrise/sunset landscape shots), and deeper color fidelity without the need for heavy sharpening or noise reduction. The SP-820UZ is respectable in daylight but struggles in shadows or higher ISOs, producing more grain that can muddy fine details.

Focusing Systems and Burst Speed: Fast Enough?

For those interested in action, wildlife, or sports photography, autofocus speed and burst shooting are critical.

The E-400 uses a phase-detection autofocus system with three focus points, including multi-area AF mode. While hardly cutting-edge (especially by modern standards), it performs admirably for its time, with decent acquisition speed in good light. However, continuous tracking is not supported, which limits its usefulness for unpredictable subjects.

The SP-820UZ employs a contrast-detection AF with face detection, more typical of compact cameras. Its autofocus can hunt noticeably in low light or complex scenes, but the extensive zoom range comes with a depth of field challenge that requires patience and the occasional manual focus attempt (even if not officially supported).

Burst rates are modest: 3 fps on the E-400 and 2 fps on the SP-820UZ, which won't satisfy professional sports shooters but are sufficient for casual photography or family events.

Still Image Quality in Different Genres

Portrait Photography

Portraits demand pleasing skin tones, smooth bokeh (background blur), and accurate focus on the eyes. The E-400’s larger sensor excels here. Its Four Thirds sensor, combined with the ability to swap lenses including fast primes at f/1.8 or f/2.8, produces creamy background defocus that isolates subjects beautifully. The E-400 lacks face and eye detection AF, so you rely on manual placement of the focus point, but with just three AF points, it’s straightforward enough - perfect for learners honing their skills.

The SP-820UZ’s fixed lens f/3.4-5.7 aperture limits shallow depth of field, making bokeh less pronounced. However, its face detection (a bonus in this category) can help beginners nail focus on their subjects’ faces. Skin rendering tends to be a bit flatter and less nuanced due to the small sensor and compact lens. Still, for casual portraits without craft-obsessed standards, it’s passable.

Landscape and Nature Photography

Here, dynamic range, resolution, lens quality, and stability dominate considerations.

The E-400’s 10MP CCD sensor, with more surface area, gathers light more effectively and captures richer tones in shadows and highlights, essential for expansive landscapes. Interchangeable lens support means you can attach sharp, wide-angle lenses that outperform the superzoom optics in image quality by a wide margin.

As an example, my long exposures of mountain ridges revealed more subtle tonal transitions and better low ISO noise in the E-400 files.

The SP-820UZ’s 14MP sensor can squeeze out higher resolution crops but at the cost of noisier shadows and less punch in highlight retention. Its ultra-wide to extreme telephoto zoom range is alluring on paper (22-896 mm!), but image sharpness drops noticeably toward the long end. This makes the camera a jack-of-all-trades but master of none for landscapes.

Neither camera offers environmental sealing, which is a bummer for rugged outdoor use.

Wildlife and Sports Photography

Wildlife and sports shooters often want fast autofocus, long reach, and shooting speed. The SP-820UZ’s massive 40x zoom is a huge asset here, enabling close-ups from a distance without extra lenses or gear.

Unfortunately, contrast-detection AF struggles to keep pace with erratic wildlife movement, especially in lower light or busy backgrounds.

The E-400’s DSLR phase-detection AF is more dependable for tracking moving subjects, but its limited AF points and 3 fps burst mode restrict its effectiveness against faster sports action.

Street and Travel Photography

Street shooters prize discretion, fast responsiveness, and portability.

The SP-820UZ’s compact size, quiet operation, and variety of semi-auto modes make it a low-profile travel companion - ideal when lugging heavy gear isn’t an option. Its built-in flash and wide zoom are versatile tools for tricky lighting and varying distances.

The E-400 is heavier, louder, and demands carrying lenses, but rewards patience with superior image quality and more creative control.

Video Capabilities: What to Expect

Back in 2006, video was not the DSLR standard. The E-400 lacks any video recording capabilities whatsoever, limiting it to still photography.

By contrast, the SP-820UZ is surprisingly well-equipped for its time and price bracket: it supports Full HD 1080p video at 30 fps and multiple lower resolutions with interesting frame rates like 120 fps for slow-motion effects, encoded mostly in MPEG-4 and H.264.

Image stabilization is not included on either camera, which can result in shaky footage unless you stabilize yourself. The absence of microphone input is a downside, however, for anyone hoping to create high-quality sound recordings alongside their video.

Interface, Viewfinder, and Screen Experience

The E-400 employs an optical pentamirror viewfinder with approximately 95% coverage - a classic DSLR feature that enables stable, lag-free composition even under bright daylight, though the magnification is on the small side (0.46x). The 2.5-inch fixed LCD screen (215K dots) is clear enough for playback and menu navigation but lacks live view or touchscreen, limiting its flexibility.

Meanwhile, the SP-820UZ drops the viewfinder completely, relying on a 3-inch TFT LCD screen with higher resolution (460K dots) for composition and review. Live view is fully supported here, which is a necessity given the lack of an optical viewfinder. However, LCD-only framing can be cumbersome in bright sunlight, and without electronic stabilization, you may find yourself wobbling more during long zoom use.

Build Quality and Reliability

Neither camera features weather sealing, which is common in their price range and era; so be cautious when shooting in wet or dusty conditions. Build quality on both is solid but utilitarian - nothing fancy or heavily reinforced.

Battery life specifics are sparse, but expect roughly 350-400 shots per charge on the E-400 (typical of DSLRs) and somewhat fewer on the SP-820UZ, given its LCD and video demands. Both accept only a single storage card each, but the E-400 uses Compact Flash or xD Picture cards - formats that are increasingly rare and pricier - whereas the SP-820UZ uses the ubiquitous SD family.

Lens Ecosystem: Growth Potential or Fixed Versatility?

The E-400’s Micro Four Thirds mount has matured into one of the most extensive and affordable lens ecosystems available today, with over 45 native lenses covering every focal length and specialty. From bright primes to affordable zooms, you can grow with this system, expanding creative horizons. Plus, third-party manufacturers make adapters to use legacy optics.

The SP-820UZ, with its fixed lens, offers no expansion but tries to compensate with a massive zoom range - making it ideal for photographers who want simplicity without lens swapping.

Connectivity and Storage

Both cameras lack wireless connectivity, Bluetooth, NFC, or GPS. USB 2.0 ports allow file transfers but not much else.

Storage-wise, the E-400’s dual compatibility (Compact Flash and xD Picture Card) is convenient for folks who may have legacy cards, though both formats are cumbersome compared to modern SD cards preferred in the SP-820UZ.

For travel and ease of use, SD cards remain the winner here.

Value for Money: What Does Your Budget Buy?

Price-wise, the Olympus E-400 often goes for around $600 on used markets today (new models long discontinued and superseded by the E-410), whereas the SP-820UZ’s street price usually hovers around $300, sometimes less in deals.

On a pure dollar basis, the SP-820UZ packs in extensive zoom and HD video for half the price, making it appealing to budget shooters needing grab-and-go versatility.

The E-400 demands more investment and lens purchases but yields significantly better image quality and expandable growth potential if you’re serious about improving your skills and creativity.
