Olympus E-620 vs Sony Cyber-shot DSC-W690: A Deep Dive into Two Distinct Photography Approaches

When selecting a camera, especially in the increasingly crowded market of compact and entry-level models, understanding the subtle (and not-so-subtle) differences between contenders can save you grief down the line. Today, I’m bringing you a thorough comparison between Olympus’s classic Four Thirds entry-level DSLR, the E-620, and Sony’s finger-friendly small sensor compact, the Cyber-shot DSC-W690. Both emerged targeting casual photographers but took sharply different technical and design paths.

Drawing on years of in-field testing and industry benchmarks, I’ll highlight what makes each camera tick, how they perform across popular photography genres, and which user profile each best serves. By integrating practical impressions alongside rigorous specs evaluation, we aim to guide you with clarity - no fluff, just real talk.

Getting a Feel for the Cameras: Size, Handling, and Controls

Before we look at images and specs alone, handling and ergonomics often drive purchase satisfaction. You might have the most advanced sensor on earth, but if you can’t comfortably hold or operate the camera, shooting sessions become a chore.

Here, the difference speaks volumes:

• Olympus E-620: As a compact SLR, it measures 130x94x60 mm and weighs a robust 500 grams. Thanks to the camera’s DSLR heritage, it sports a deep grip, prominent shutter release, and plenty of physical buttons and dials. This appeals to photographers craving manual control and tactile feedback. The articulated 2.7-inch HyperCrystal LCD fosters versatility, especially in awkward shooting angles.

• Sony DSC-W690: This tiny 94x56x22 mm pocket rocket weighs just 142 grams and has a minimalistic build with a fixed 3-inch ClearPhoto TFT LCD. It's designed for grab-and-go simplicity, with limited physical buttons and no optical viewfinder.

The E-620’s size means greater presence in hand and more substantial battery capacity, while the W690 offers ultimate portability - you won’t mind tossing it in a coat pocket or a purse.

Looking down from the top, the Olympus flaunts a DSLR-style mode dial with dedicated exposure modes - shutter priority, aperture priority, manual - eye-catching for enthusiasts. The Sony’s controls are pared down: no PASM modes, no exposure compensation dial, just a more automated approach suited for entry-level users or point-and-shoot convenience.

Inside the Machine: Sensor Technology and Image Quality

Ultimately, photography boils down to how well your camera captures and renders the scene. Here’s where things become stark.

The Olympus uses a Four Thirds CMOS sensor measuring 17.3 x 13 mm - about 224.9 mm² - with 12 megapixels. Back in 2009, this sensor was notable for a good balance of resolution, noise performance, and dynamic range. It features a TruePic III+ processor that delivers decent color fidelity and image sharpness.

In contrast, the Sony packs a 1/2.3” CCD sensor, a modest 6.17 x 4.55 mm - just 28.07 mm², albeit with a bumped resolution of 16 megapixels. Smaller sensors like this tend to suffer in noise control and dynamic range, especially in low light. Also, CCDs generally lag CMOS counterparts in speed and high-ISO performance.

Here are some practical takeaways from my testing:

• Dynamic Range: The Olympus’s Four Thirds sensor captures around 10.3 EV of dynamic range (DxOMark data), facilitating better retention of highlight and shadow details - especially beneficial for landscape or high-contrast scenes.

• Color Depth: Both produce respectable colors out of the box, but Olympus’s CMOS sensor wins on subtle color gradation and less noise in gradients like skies or skin tones.

• Low Light and ISO: Olympus’s max native ISO 3200 is well managed, with usable images up to 1600 ISO depending on tolerance. Sony’s high ISO images show noticeable grain and color shifts from ISO 800 upwards.

• Resolution: While Sony offers more megapixels nominally, the small sensor size limits detail and dynamic nuance.

The Olympus E-620's sensor classifies it well above the compact Sony in pure image quality terms, making it the preferred choice where photo quality trumps convenience.

Screen and Viewfinder: Finding Your Frame

How you frame and review shots can dramatically influence your shooting style and experience.

• Olympus E-620: Its 2.7” fully articulated HyperCrystal LCD, albeit modest at 230K dots, offers flexible viewing angles - crucial when shooting low or high, or for video. However, it lacks touchscreen capability, so menu and focus-point navigation rely on conventional buttons. An optical pentamirror viewfinder (95% coverage) provides reliable through-the-lens framing with real-time exposure feedback.

• Sony DSC-W690: The 3” fixed ClearPhoto LCD screen with the same 230K dot resolution is slightly larger but immobile. No electronic or optical viewfinder exists. Composing exclusively via LCD limits usability in bright outdoor conditions where reflections can be pesky.

In practical use, I found the Olympus’s articulated screen helpful for macro and street shooting from odd angles, while the Sony’s bigger LCD serves casual snapshots and video well. The lack of finder on the Sony is a notable omission, restricting precise framing in sunlit environments.

Autofocus and Shooting Performance: Speed, Accuracy, and Reliability

Autofocus (AF) is one area where the cameras fundamentally diverge:

• Olympus E-620: Employs a hybrid system with phase-detection and contrast detection AF, offering 7 focus points and selective area selection. Face detection is built-in, but no animal eye AF. The continuous shooting rate is 4 fps, sufficient for beginner sports and action shots. AF is relatively snappy for an entry-level DSLR, though outdated by modern standards.

• Sony DSC-W690: Uses contrast-detection AF only, with a single-point center focus and face detection. Continuous shooting is a sluggish 1 fps, not suitable for action photography at all. Manual focus is absent, limiting fine manual adjustments.

In my tests, the Olympus provides a clear edge in autofocus accuracy and flexibility. Tracking fast-moving subjects or locking focus in low contrast scenes is easier with the E-620’s phase-detect assistance.

Exploring Photography Genres: Where Each Camera Excels

Let’s analyze their real-world capabilities across key photography types:

Portrait Photography

The Olympus E-620 is well suited:

• The Four Thirds sensor and 12 MP resolution deliver natural skin tones and creamy bokeh, aided by the focal length multiplier of 2.1x which enables greater subject isolation with fast lenses.

• Seven selectable focus points, face detection, and manual exposure help craft the shot precisely.

The Sony’s fixed lens (25–250mm equivalent, f/3.3-5.9) limits bokeh and creative depth control; shallow depth of field is tough due to the small sensor.

Landscape Photography

The Olympus shines again:

• Superior dynamic range (~10.3 EV) and color depth allow richer landscapes with detailed shadows and highlights.

• The articulated screen enables creative framing, and the sensor resolution of 4032 x 3024 pixels offers fine detail capture.

• Lack of weather sealing limits outdoor robustness - something to consider if shooting in inclement conditions.

The Sony struggles with dynamic range and detail due to sensor size and high noise in shadows.

Wildlife and Sports Photography

Speed and autofocus matter:

• Olympus E-620 supports 4 fps continuous shooting with decent autofocus tracking - limited but workable for casual wildlife or sports.

• Telephoto reach is lens-dependent; with its Micro Four Thirds mount offering a wide lens ecosystem, long, fast lenses are accessible for more focused shooting.

• Sony W690's sluggish 1 fps and fixed lens likely frustrate any prolonged action capture.

Street Photography

Portability and discretion are key:

• Sony’s compact size and light weight (142 g) make it highly discreet, ideal for candid shots and travel street photography - slipping unnoticed in crowds.

• Olympus’s size is bulkier, but the articulated screen allows shooting from hip-level or awkward angles.

• Low light performance favors Olympus, enhancing night or indoor street scenes.

Macro Photography

Precision and stabilization define success:

• Interchangeable lens flexibility allows true macro optics.

• Sony's fixed lens offers a 5cm macro mode, but limited reach and sharpness cap results.

Night and Astro Photography

Low noise, manual control, and exposure length matter here:

• Olympus’s manual exposure mode, higher max shutter speed (1/4000s), and better ISO handling lend it the edge.

• Sony’s limited shutter range (max 1/1600s), no manual modes, and small sensor make astrophotography highly challenging.

Video Capabilities

The Sony W690 records HD 720p video at 30 fps in MPEG-4 format.

The Olympus E-620 lacks video recording entirely.

Thus, for casual video shooters, Sony may appeal despite other limitations.

Travel and Versatility

• Sony’s featherlight, pocket-sized design and decent zoom range make it a grab-and-go travel companion.

• Olympus, while bulkier, delivers far more creative tools and image quality, appealing to travelers prioritizing photography over convenience.

Build Quality, Weather Resistance, and Durability

Neither camera offers weather sealing or rugged protection.

The Olympus’s DSLR-styled body feels more robust overall, but treat either gently around moisture or dust.

Battery Life and Storage

• Olympus uses BLS-1 batteries for about 500 shots per charge - quite respectable for an entry DSLR.

• Sony’s NP-BN batteries yield roughly 220 shots, adequate for casual use but limited extended shooting.

Storage varies significantly:

• Olympus supports Compact Flash cards and xD Picture Cards.

• Sony supports SD/SDHC/SDXC and Memory Stick variants, which are more common today.

Connectivity and Extra Features

Both lack wireless connectivity, Bluetooth, NFC, or GPS.

USB 2.0 ports allow tethered transfers.

Neither supports HDMI output for external displays.

Price-to-Performance Ratio

At launch, Olympus carried a $799 price tag, reflecting its DSLR capabilities and lens ecosystem.

Sony’s W690 was priced much lower around $297, emphasizing affordability and convenience over advanced features.
