Olympus E-400 vs Olympus SZ-10: A Deep Dive Into Two Very Different Cameras

When I sat down to compare the Olympus E-400 and the Olympus SZ-10, I knew I was looking at two fundamentally different beasts. The E-400 is a classic compact DSLR from the mid-2000s with a Micro Four Thirds mount, while the SZ-10 is a 2011-era small sensor superzoom compact. It’s not your typical head-to-head camera battle since one is a barebones DSLR system camera and the other a pocketable fixed-lens zoom. But after testing both extensively in controlled lab settings and through real-world shooting over the years, I’ve gathered a trove of insights to help you decide which might suit your photography style best.

My testing spanned all major photography genres and environments, including studio portraiture, landscape scenes, wildlife action, and even astrophotography. Along the way, I measured sensor performance, autofocus reliability, ergonomics, and image quality using industry-standard targets. I’ll be candid about the strengths and caveats of each, offering clear purchase recommendations depending on your needs and budget.

So let’s jump in and peel back the layers on these Olympus cameras.

Size, Handling & Ergonomics: Who Fits Your Hands and Pocket?

The first thing I noticed handling these two cameras side-by-side was their sheer physical contrast. The Olympus E-400 is essentially a compact SLR with a traditional DSLR body shape, but surprisingly lightweight at 435 grams considering its all-metal construction. It measures a modest 130 x 91 x 53 mm, which makes it one of the smallest DSLRs ever made. Holding it, I appreciated its sturdy feel - solid, not plasticky - giving confidence during extended shoots.

Contrast this with the Olympus SZ-10’s seriously pocketable design at 106 x 67 x 38 mm and only 215 grams. It’s the kind of camera that slides easily into a jacket pocket or small bag without discomfort. Though plastic-bodied, the SZ-10 feels well-assembled and balanced. The fixed lens adds minimal bulk, making it incredibly convenient for travel and street photography.

Ergonomically, the E-400 offers larger, more tactile buttons and a traditional DSLR grip, although by today’s standards the control layout feels a bit sparse and dated. The SZ-10’s controls fit its compact scale, but buttons are small and require some navigation through menus, which can slow you down in fast-paced situations.

From the top view, the E-400 gives a DSLR vibe with physical dials and a pop-up flash, while the SZ-10 uses more digital menu-driven exposure modes with a fixed lens, lacking a viewfinder altogether (relying solely on its rear screen). An important point if you prefer composing via viewfinder in bright conditions.

Overall, if you want DSLR ergonomics and a full camera feel, the E-400 feels more professional and confident in hand. For lightweight portability and snapshooting ease, the SZ-10 is a clear winner.

Sensor Technology & Image Quality: A Battle of Generations

Digging beneath the surface into sensor tech reveals a striking difference. The E-400 uses a Four Thirds-type 17.3 x 13 mm CCD sensor with 10 megapixels, huge compared to the SZ-10’s tiny 1/2.3” 6.17 x 4.55 mm CCD sensor but sporting a higher pixel count of 14 megapixels. Despite the SZ-10’s higher pixel count, its tiny sensor area (just 28.07 mm² vs. 224.9 mm² for the E-400) places hard limits on image quality, dynamic range, and noise control.

The Four Thirds system sensor on the E-400 captures cleaner images with better color depth and wider dynamic range. Shadows and highlights retain detail much better, especially in challenging mixed-light scenes like dappled forest light or indoor lighting with window highlights. The SZ-10's sensor, while acceptable for snapshots, struggles with noise above ISO 400 and loses detail quickly in low light.

In practical shooting, the E-400 produces images with richer tonal gradations and less color banding - important for post-processing latitude. I tested RAW files from the E-400 (it does shoot RAW), which is a boon for anyone serious about editing. The SZ-10 only stores JPEGs, which limits your flexibility.

LCD and Interface: Viewing and Navigating Your Shots

Moving to the rear controls, the E-400 sports a fixed 2.5-inch LCD with only 215k dots of resolution. By modern standards, it’s dim and low-res making it harder to critically evaluate focus or exposure in the field. However, it offers a straightforward menu system with dedicated buttons for common controls, which I appreciated during structured shoots.

In comparison, the SZ-10 has a significantly larger 3.0-inch screen with 460k dots, offering much sharper image review and better brightness, especially under daylight. Since the SZ-10 has no viewfinder, the rear screen is essential, and Olympus did well here. The touchscreen absence on both cameras is noted, but not surprising given their vintage.

Interface-wise, the SZ-10 menus are more streamlined for casual users, with well-labeled icons and quick access to basic adjustments - helpful for beginners and travelers relying on auto modes. The E-400 demands more familiarity and manual input but rewards this with creative control.

Autofocus Performance: Speed, Accuracy, and Usability

The Olympus E-400 features a 3-point phase-detection autofocus system typical of early DSLRs - with center-weighted focus and limited cross-type points. While basic, it allows for decent single-shot autofocus in good lighting. Continuous autofocus mode performs reasonably at 3 fps shooting rate (still rather slow today).

During testing, I found the E-400’s AF a bit sluggish and prone to hunting in low light or low contrast subjects, but it can lock firmly on subjects in daylight or studio lighting. Lack of face or eye detection means you need to be deliberate with focusing.

On the other hand, the Olympus SZ-10 employs a contrast-detection system with face detection, locking onto faces fairly reliably in well-lit conditions. However, the continuous AF performance is limited, shooting only 1 fps continuous - not ideal for fast action. Focus hunting is common in low light due to slower contrast detection AF, but macro focus down to 1cm was accurate and impressive in bright conditions.

Bottom line: The E-400’s SPD AF is better suited for deliberate photography where speed is less critical, while the SZ-10 favors casual portrait snapshots with face detection in good light.

Lens Ecosystem and Versatility: Adapt or Fixed

One of the most compelling strengths of the Olympus E-400 is its Micro Four Thirds lens mount compatibility. At launch, it supported 45 lenses with a 2.1x focal length multiplier, allowing everything from ultra-wide to telephoto lenses with interchangeable flexibility. Whether you want to shoot landscapes, wildlife, or macro, the E-400 sets a strong foundation.

The SZ-10, by contrast, has a fixed zoom lens ranging from a versatile 28-504mm equivalent (18x zoom). This allows for convenient high reach without changing lenses but means you’re stuck with a variable aperture (F3.1-4.4) and compromises often associated with superzooms - softness in corners, distortion, chromatic aberration.

If your photography demands variety and stepping into professional lenses or manual glass, the E-400 is a far better lifelong investment. For pocket-ready simplicity and one-lens convenience, SZ-10 can suffice at the cost of ultimate image quality.

In the Field: Practical Photography Discipline Tests

Now let me share how these two cameras performed across various photography genres.

Portrait Photography

The E-400’s larger sensor, ability to swap fast lenses, and manual focus control make it superior for portraits. Skin tones render naturally with good depth and pleasant bokeh depending on the lens choice. The lack of face detection means you need to frame carefully, but eye-level optical viewfinder helps nail focus.

The SZ-10’s face detection autofocus works well for snapshots and casual portraits, especially with zoomed-in framing to isolate subjects. However, skin tones are less natural, often looking flatter or washed out, and the fixed lens bokeh at long telephoto settings is mediocre.

Landscape Photography

Olympus E-400 shines here because of its better sensor dynamic range and RAW shooting allowing highlight recovery. Combined with weather-resistant lenses from the Four Thirds system (though camera body itself isn’t sealed), it’s well suited to diverse landscape conditions.

The SZ-10 can capture landscapes quickly thanks to its zoom range, but small sensor size limits dynamic range - shadows get lost in forests or twilight scenes. Lack of manual aperture control restricts creative exposure. Also, no weather sealing shrinks its outdoor appeal.

Wildlife and Sports Photography

Neither is designed for serious action. The E-400’s modest 3 fps burst and limited 3-point focus are slow compared to modern gear but can handle casual wildlife shooting with telephoto lenses from the MFT lineup.

The SZ-10’s superzoom gives reach needed to capture distant wildlife quickly, but slow autofocus and 1 fps shooting greatly limit candid action capturing. Tracking fast subjects is frustrating.

Street Photography

Here, the SZ-10’s portable size and quiet operation make it a nice street companion for spontaneous shots, while the E-400’s larger body is less discreet though optical viewfinder aids composition in bright light.

Both fare poorly in very low light - SZ-10 limited by sensor noise, E-400 by slow AF and max ISO of 1600.

Macro Photography

E-400’s lens interchangeability lets you select dedicated macro glass for fine detail and shallow depth of field. The SZ-10 impressively focuses down to 1cm but has limited DOF control and less sharpness at close range due to lens compromises.

Night and Astrophotography

E-400’s Four Thirds sensor and RAW capability are a plus, allowing better noise control and post-processing for starscapes or nocturnes. SZ-10 struggles with noise and fixed aperture wide open at night.

Video Capabilities

E-400 doesn’t offer video recording, reflecting its 2006 DSLR era. The SZ-10 shoots 720p VGA motion JPEG video - basic, but usable for casual movies. It also implements sensor-shift stabilization which helps handheld video somewhat.

Travel Photography

SZ-10’s compactness, long zoom range, and decent battery life (around 220 shots) makes it a great grab-and-go camera, ideal for tourists and casual travelers. E-400’s size, weight, and battery life are modestly limiting for travel, though image quality rewards the carry.

Professional Working Use

The E-400's support for RAW, tethering (via USB 2.0), and professional lens options make it more viable for entry-level pro use, especially studio or portrait work. SZ-10 lacks these professional tools.

Reliability, Build Quality, and Battery Life

While neither camera is weather-sealed, the E-400 boasts a more solid build with metal chasses, giving it durability on repeated rigorous use. The SZ-10’s plastic body is lighter but less rugged, better suited for casual use.

Battery life on the E-400 isn’t specified in detail but typical DSLRs of its generation offered around 300-400 shots per charge. The SZ-10 officially rated for 220 shots, typical for compact zooms.

Storage-wise, E-400’s use of Compact Flash and xD cards may be limiting today, while SZ-10’s SD card slot offers more convenient and widely compatible storage media.

Connectivity and Extras

SZ-10 features Eye-Fi wireless card compatibility and an HDMI output for easy image sharing and playback on TVs - useful for snapshots and family use. E-400 lacks wireless connectivity and HDMI, reflecting its era.

Both cameras forego Bluetooth, GPS, or NFC.

Price-to-Performance Analysis

At launch, the E-400 retailed at around $599 with body only, targeted at entry-level enthusiasts ready to expand with lenses. The SZ-10 was $299 targeted at casual shooters wanting zoom range in a compact package.

Today, the E-400 can be found secondhand for less but requires investment in lenses and accessories for full use. The SZ-10 remains a budget compact for simple snapshooting, with lower total costs but also limited growth.

Summarizing Scores and Genre-Specific Performance

In my scoring system, the Olympus E-400 demonstrates solid image quality, versatility, and better controls across most genres, albeit with slower autofocus and dated ergonomics. The SZ-10 shines in portability and zoom range but falters in image quality and advanced functionality.
