Olympus E-400 vs Olympus E-420: A Hands-On Comparative Review for Budget-Conscious Photographers

When diving into the classic DSLR realm, especially from the Olympus lineup, two cameras often come up for debate: the Olympus E-400 and the Olympus E-420. Both models cater to entry-level DSLR buyers looking for compact bodies and solid image quality without dropping a ton of cash. Having put thousands of cameras through my hands over the last 15 years, I went back to test these two in detail - not in a lab only, but across real photography scenarios with a critical eye toward value, ergonomics, and practical performance.

Let’s unpack how the E-400 and E-420 stack up across portraiture, landscapes, wildlife, and more with first-hand insights you won’t find easily elsewhere. If you’re eyeing one of these classics, this guide will save you hours weighing feature lists and vague specs.

Getting the Feel: Size, Ergonomics & Build Quality

At first touch, Olympus earned kudos by packing SLR performance into compact packages targeting enthusiasts who prefer something more pocketable than clubs for thumbs-sized DSLR beasts.

Both cameras sport a similar body style - slim, lightweight, and surprisingly easy to wield for prolonged periods. Not surprisingly, their dimensions match exactly at 130x91x53 mm with around 425–435 grams weight. However, minor grip contour differences and button positioning slightly influence handling.

The E-400 feels a tad chunkier in the hand, partially due to slightly fattened contours around the grip and a thicker top deck. The E-420 refines this with smoother lines and a more comfortable thumb rest - a relief in long shootdays. Despite their plastic construction, these models avoid the cheap toy vibe and provide robust enough chassis for casual users.

From a durability standpoint, neither camera offers environmental sealing or shockproofing. So you’ll need care outdoors, especially in moisture or dusty situations - a familiar trade-off at this price level from the mid-2000s era.

Top-Deck Controls & User Interface: Getting to Know Your Machine

Controls control your creativity, right? In testing, the E-420 shows incremental improvements in button layout over the E-400.

Both sport relatively minimal top-plate controls and a pentamirror optical viewfinder, but the E-420 adds manual exposure mode alongside aperture and shutter priority (whereas the E-400 lacks manual exposure). This seemingly small addition gives the E-420 more control for enthusiasts looking to expand their skills.

Buttons feel shallow on both, but the E-420’s dial and placement lend a slightly more natural dial-in experience. Neither has illuminated buttons, so shooting in near-darkness requires muscle memory.

Sensor and Image Quality: The Heart of the Matter

The E-400 features a 10MP Four Thirds CCD sensor, while the E-420 steps up with the same resolution but a CMOS sensor paired with the TruePic III image processor.

This difference is pivotal: CMOS sensors generally excel at reducing noise and enhancing dynamic range compared to older CCD units, a fact reflected in real-world shooting. My side-by-side test shots revealed improved shadow detail and slightly better color reproduction in the E-420, especially under mixed lighting - a big plus for landscape and street photographers who often encounter challenging contrast.

At base ISO (100), both cameras produce clean images at their maximum resolution of 3648x2736 pixels with a native 4:3 aspect ratio. However, pushing ISO beyond 400 on the E-400 quickly introduces visible grain and color degradation, while the E-420 handles up to ISO 800 with more grace, maintaining workable image quality.

LCD Screens and Viewfinder Experience: Framing and Review

Both cameras dodge the trendy articulating screen trend, sticking to fixed 2.5-inch (E-400) and 2.7-inch (E-420) LCDs respectively. Resolutions hover at modest levels: 215k dots on E-400 and slightly refined 230k dots on E-420.

Neither screen dazzles by today’s standards, but the E-420's larger and marginally sharper screen assists in composing shots and exploring menus more comfortably. Most notably, the E-420 introduced live view mode, enabling real-time screen preview - a feature absent on the E-400. This aids macro and studio shooters who benefit from precise manual focusing, especially when coupled with the camera’s contrast-detection autofocus in live view.

The optical pentamirror viewfinder on both models offers about 95% frame coverage and 0.46x magnification, sufficient for clearer composition than point-and-shoots but not league-leading for critical manual focusing or tracking fast action. Still, for beginning DSLR owners, these specs do the job well.

Autofocus Systems: Speed, Accuracy & Practical Impact

Here lies a critical divergence. The E-400 uses a phase-detection AF with three focus points, but no continuous AF tracking, face detection, or eye detection features. The E-420 retains the same 3-point AF system but benefits from the addition of contrast-detection AF in live view, providing finer manual focus confirmation and improved flexibility.

In real-world use, both cameras are adequate for static scenes - portraits, landscapes - but struggle with dynamic subjects. Burst shooting tops out at 3 fps (E-400) and 4 fps (E-420), not exactly professional sports camera territory.

I tested quick-moving subjects (running kids, dogs) and found AF lag caused several missed frames, especially on the E-400, which felt sluggish in focus acquisition. The E-420 improves this slightly but still isn't ideal for wildlife or sports shooters needing relentless precision.

How Do These Cameras Perform Across Photography Genres?

Portrait Photography: Skin Tones, Bokeh, and Detail

For portraits, lens choice and sensor performance are decisive. Both cameras sport the Micro Four Thirds mount with extensive native lens ecosystems numbering about 45 lenses between them. The focal length multiplier (~2.1x) means a 25mm prime acts like 50mm in 35mm terms - classic portrait territory.

Skin tones on both cameras render pleasantly neutral, though the E-420’s CMOS sensor pulls ahead slightly in preserving subtle tone gradations and richer mids. The CMOS sensor also handles highlight roll-off more gracefully, avoiding blown-out highlights on cheekbones or foreheads.

The smaller sensor yields more depth of field than full-frame options, so massive background blur (bokeh) requires wide-aperture lenses, but both cameras allow satisfying subject isolation when paired with the right glass.

Landscape Photography: Dynamic Range and Weather Resistance

Landscape shooters will enjoy the resolution and sharpness from both 10MP sensors but lean toward the E-420 for superior dynamic range (~10.4 EV scored in lab metrics) compared to the limited dynamic window of the E-400’s CCD sensor.

However, neither model features weather sealing, so be cautious shooting in rain or dusty environments typical of landscapes. Consider ruggedizing accessories or protective bags. Both cameras pick up broad tonal range in greens and blues, but shadows unlock with more latitude on the E-420, valuable when post-processing.

Wildlife Photography: Autofocus and Burst Rates

Wildlife photographers demanding snappy autofocus and rapid frames will find these cameras wanting. Three-focus points and max bursts of 3–4 fps can’t realistically track erratic bird or mammal movements.

If you’re serious about wildlife, investing in newer cameras (or Olympus’s later OM-D offerings) with better AF arrays and high frame rates is advisable. That said, casual wildlife snaps in good light are achievable, especially with long telephoto lenses mounted.

Sports Photography: Tracking and Low Light

Much like wildlife, sports require rapid acquisition and accurate tracking. The low AF point count and modest burst rates limit these cameras to slow-paced sports or intermittent action.

Low light conditions worsen matters. The E-420’s CMOS sensor handles ISO noise better but still struggles beyond ISO 800.

Street Photography: Discretion and Portability

Here, both cameras shine due to their compact, lightweight builds and silent shutter speeds down to 1/60s max. Neither offers silent electronic shutter options, but their quiet operation makes them neat companions for candid streetwork.

The E-420’s live view mode aids composing discreetly, avoiding the eye-contact that can spook subjects - something I appreciated during urban assignments.

Macro Photography: Magnification and Focus Precision

Thanks to live view and contrast-detection AF on the E-420, macro photography gains a fairly serious tool. The E-400’s lack of live view handicaps critical focus work at close distances.

Neither model has in-body stabilization, so complement with stabilized lenses or tripods for the best results.

Night and Astrophotography: ISO and Exposure Control

Neither camera excels here. ISO ceilings are capped at 1600 native, and noise at high ISOs is quite visible. Plus, absence of bulb mode or exposure bracketing reduces flexibility for long exposures.

Both handle timer modes (2 or 12 seconds), which can allow basic nightshoots, but for serious astro, one should look elsewhere.

Video Capabilities

Both cameras lack video recording features entirely, reflecting their mid-2000s heritage before movies became standard.

Prospective buyers wanting hybrid photo/video cameras will need to explore newer models.

Travel Photography: Versatility, Battery Life, and Size

Travelers who want a lightweight DSLR with no charme sans bulk can trust these models. The E-420’s slightly lighter body and longer battery life (around 500 shots per charge) edge it ahead of the E-400, whose battery life remains undocumented but is known to be shorter.

Tiny size coupled with Micro Four Thirds lenses means a smaller kit overall, an excellent match for backpacks and quick grab-and-go shots.

Professional Workflows: Reliability and File Formats

Both cameras shoot RAW, enabling post-processing freedom. Olympus RAW files are well supported in popular editors like Lightroom and Capture One.

Manual controls are more comprehensive on the E-420, catering better to advanced users, though shutter priority and aperture priority modes exist on both.

Technical Breakdown: Inside Olympus E-400 vs E-420

Lens Ecosystem and Compatibility

Both cameras take advantage of the Micro Four Thirds mount system, backed heavily by Olympus as well as Panasonic and third-party manufacturers. Micro Four Thirds lenses are famously compact and affordable, perfect for shooters on a budget or seeking travel convenience.

You’ll find everything from wide primes, fast portrait lenses, to macro and super-telephoto zooms fitting these bodies. Autofocus motors are lens-dependent but generally smooth and quiet with native options.

Connectivity and Extras

Neither camera offers wireless connectivity, GPS, HDMI, or advanced USB options beyond USB 2.0. This aligns with their mid-2000s design but feels limiting a decade later.

The lack of touchscreen and no video output restrict usage in modern hybrid workflows, but tethered shooting via USB might be possible with third-party software.

Real-World Performance Gallery Samples

To back these assessments with actual results, I shot a variety of scenes on both cameras using standard 25mm f/1.8 primes and kit lenses.
