Olympus E-420 vs Samsung WB750: Decoding the Practical Photography Value in Two Different Worlds

Choosing a camera often means deciding between different philosophies of design, sensor size, lens flexibility, and intended use. Today, we pit two distinctly different cameras head-to-head: the Olympus E-420, a compact entry-level DSLR from 2008 heralding Micro Four Thirds innovation, against the 2011 Samsung WB750, a small-sensor superzoom compact designed to cram versatility into a pocketable frame.

While they overlap marginally in market appeal - budget-conscious shooters craving decent image quality - their technical DNA and shooting experiences couldn’t be more different. Over years of testing thousands of cameras, I’ve learned that understanding exactly what you want to shoot and how radically different cameras perform in the real world lifts confusion and noise from your decision.

Let’s dive into the core of these cameras, their strengths, compromises, and who should consider each as their next photographic sidekick.

Size, Handling, and Ergonomics: The Feel Factor Matters

Right from the get-go, you notice the physical contrast between the E-420 and WB750. The Olympus is a compact SLR body, weighing 426g with a footprint of 130x91x53mm. The Samsung WB750, true to its compact superzoom category, is smaller and lighter at 193g and 105x59x25mm.

This size difference truly reflects in the handling. The E-420, built as an "entry-level DSLR," accommodates a more comfortable grip, bigger body controls, and room for physical dials and buttons - even though it lacks illuminated buttons, the layout is intuitive and reassuring for those who prefer tactile feedback. Its hand grip is modest but functional, an important aspect when you consider shooting for extended periods or when attaching larger lenses.

Conversely, the WB750’s compact, almost point-and-shoot-like frame makes it incredibly easy to slip into a pocket or small bag. However, that portability comes at the expense of grip security and precise control placement. If you’re someone who shoots on the go and prizes stealth over clutching something chunky, the WB750 delivers. But the smaller body and lighter weight mean fewer physical controls and less room for customization - a trade-off especially palpable for photographers who like clubs for their thumbs in the form of dedicated buttons.

Top View Control Layout

Controls layout is crucial, especially when you want quick access to exposure settings and focus modes.

The Olympus E-420 sports a traditional top dial and well-spaced buttons, making switching between shutter priority, aperture priority, and manual modes straightforward. The WB750, in typical superzoom style, features multifunctional buttons and a simpler dial system, which may bewilder users craving direct controls.

Sensor and Image Quality: The Heart of the Matter

The foremost technical difference lies in their sensors.

The Olympus E-420 wields a Four Thirds CMOS sensor measuring 17.3x13mm with a total surface area of ~225 mm², delivering 10MP resolution. Though modest by today’s megapixel standards, this sensor size and pixel count were competitive in 2008 for entry-level DSLRs. Its TruePic III processor aids in decent color rendition and noise control.

In contrast, the Samsung WB750 uses a much smaller 1/2.3" BSI-CMOS sensor (6.17x4.55mm, ~28 mm²), with a slightly higher resolution of 13MP. The built-in BSI (Backside-Illuminated) technology enhances low-light response to some extent but is fundamentally limited by its physical size.

What this means in practice:

• The E-420’s larger sensor area means better light gathering per pixel, superior dynamic range, richer color depth, and cleaner high ISO performance. Indeed, DxO Mark places its color depth at 21.5 bits and dynamic range at 10.4 EV - a respectable performance that sports shooters, portrait shooters, and landscape lovers can appreciate.

• The WB750, despite the higher megapixels, cannot rival the E-420’s depth or low-light capabilities due to sensor size constraints. This limits its image quality, particularly in challenging lighting conditions.

If image quality and the ability to create shallow depth-of-field (bokeh) are priorities, the Olympus excels - not only from sensor size but due to its interchangeable lenses offering wide-aperture choices.

Screen and Interface: Your Window to the Scene

Looking at each camera’s rear screen, you can gauge how they suit modern compositional and review needs.

The Olympus E-420 offers a fixed 2.7-inch screen with 230K dot resolution - modest by today’s standards but serviceable at the time. The Samsung WB750 ups the ante with a larger, 3-inch 460K LCD, providing a crisper display for framing and reviewing images.

Still, the lack of touch, tilt, or swivel mechanisms on both models limits creative flexibility for awkward angles, something that’s become more standard even in entry-level cameras now.

Autofocus and Shooting Speed: Capturing the Moments

Autofocus (AF) performance can make or break your shooting experience, especially in dynamic environments like wildlife or sports.

• The Olympus E-420 uses a hybrid AF system: contrast and phase detection with 3 AF points. While not expansive by today's standards, its ability to perform continuous AF (albeit limited) allows it to track moving subjects somewhat reliably. However, it lacks face or eye detection, hampering portrait precision.

• The Samsung WB750 relies on contrast detection AF, with face detection but no continuous AF capabilities or multiple focus points. Its AF responsiveness in good light is decent but can lag in low light or complex scenes.

Shooting speed further differentiates them: The E-420 caps in at 4 fps for continuous shooting, whereas the WB750 boasts a speedier 10 fps burst mode. However, the smaller buffer and JPEG-only shooting on Samsung mitigate this speed advantage for sustained shooting.

Lens Flexibility vs Built-in Zoom: The Everlasting Debate

The Olympus E-420 belongs to the Micro Four Thirds mount system, compatible with about 45 varied lenses, from prime fast apertures to versatile zooms.

This interchangeable configuration affords vast creative control - whether you want to shoot ultra-wide landscapes, macro close-ups, or portraits with creamy bokeh.

In contrast, the Samsung WB750 has a fixed 24–432mm equivalent zoom lens (an 18× zoom range) with an aperture range of f/3.2–5.8. This impressive zoom versatility is a convenience boon for travel or casual multipurpose shooting but sacrifices optical quality and aperture speed, which directly affect image sharpness and background blur.

On the topic of macro focus distance, the WB750 can focus as close as 5cm, making it a capable compact option for close-up photography without switching lenses. The Olympus relies on compatible macro lenses.

Real-World Performance in Different Photography Genres

Let’s explore how these cameras perform across common photography disciplines.

Portrait Photography

In portraits, capturing natural skin tones, sharp eyes, and smooth bokeh is king.

• Olympus E-420: With its larger sensor, interchangeable lenses, and manual exposure modes, you can precisely control depth of field and subject isolation. Its 3-point AF without face/eye detection is a hinderance, meaning you’ll need to focus carefully, ideally in single AF mode.

• Samsung WB750: The built-in lens and face detection aid casual portraits. However, limited aperture and smaller sensor size reduce artistic bokeh potential. The camera’s lack of RAW also restricts color grading flexibility.

Landscape Photography

Details and dynamic range matter deeply here.

• The E-420 shines with its wider dynamic range and ability to use high-quality MFT lenses optimized for sharpness and minimized distortion.

• WB750’s small sensor and high zoom exacerbate noise and reduce image quality, especially in shadows.

Wildlife and Sports

High frame rates and reliable autofocus tracking matter most.

• The WB750’s fast 10 fps burst and extended telephoto reach up to 432mm equivalent are huge advantages for casual wildlife and sports shooters who need reach.

• Olympus’s slower 4 fps and limited 3 AF points make fast-moving subjects tricky.

Despite this, the E-420’s bigger sensor produces better image quality, aiding severe cropping in post to simulate zoom.

Street Photography

Portability and discretion rule.

• WB750’s compact size and quiet operation make it perfect for candid street shots.

• E-420’s larger body makes it less discreet, but its optical viewfinder is beneficial for bright conditions.

Macro Photography

The WB750’s 5cm close focusing beats the E-420’s need for a dedicated macro lens.

Night and Astro Photography

Higher sensor quality and noise control dominate here. The Olympus with ISO maximum of 1600 (native) and slightly better noise scores is the preferred choice over the WB750 (max ISO 3200 but noisier).

Video Capabilities

The WB750 supports Full HD 1080p at 30 fps, along with various lower resolutions, making it a strong video shooter for casual users, though lacks mic ports or advanced features.

The Olympus E-420 does not offer video recording, being firmly a stills-first DSLR.

Build Quality and Weather Resistance

Neither camera offers environmental sealing or weatherproofing, making them susceptible to dust or moisture in harsh situations.

Battery Life and Storage

Olympus’s battery life is exceptional at approx. 500 shots, around double most compacts, owing to DSLR efficiency and optical viewfinder.

Samsung’s battery life figures aren't available but given its compact size and LCD reliance, expect less endurance.

Storage types also differ: Olympus supports CompactFlash and xD Picture Cards (somewhat archaic), whereas Samsung uses the ubiquitous SD/SDHC/SDXC cards.

Connectivity and Port Options

Neither supports Wi-Fi, Bluetooth, or GPS, but:

• Samsung WB750 offers HDMI output for easy video display on TVs.

• Olympus only has USB 2.0 for tethered transfer.

Price and Value Assessment

Clearly, pricing skews the decision.

• Olympus E-420 historically priced around $999, reflecting DSLR entry-level standards and lens ecosystem value.

• Samsung WB750 retailed for ~ $338, aiming at a budget crowd wanting long zoom and HD video performance without fuss.
