Olympus E-620 vs Sony HX100V: An Expert Comparison for the Discerning Photographer

Choosing the right camera can feel overwhelming, especially when the options span distinct categories like an entry-level DSLR and a bridge superzoom. Here I take a deep dive into the Olympus E-620, an early Micro Four Thirds DSLR classic, and the Sony Cyber-shot DSC-HX100V, a versatile bridge camera with extensive zoom capabilities. They each offer unique strengths, cater to different shooting styles, and come from separate design philosophies. With over 15 years of hands-on testing experience, I’ll cut through the specs and marketing to reveal how these two compare in real-world performance, across all photography disciplines you care about.

At a Glance: Physical Design and Handling

First impressions matter. I’d suggest starting with how the camera feels and fits in your hand since ergonomic comfort impacts your shooting experience more than we often realize.

The Olympus E-620 sports a compact DSLR body typical of the late 2000s Micro Four Thirds lineup. Its dimensions - roughly 130 x 94 x 60mm - and a weight of 500g make for a lighter DSLR than many of its contemporaries. It bridges the gap between beginner and enthusiast genres with intuitive controls arranged for quick manual shooting.

The Sony HX100V, meanwhile, looks like a mini SLR with a chunky grip and a lengthy zoom barrel. Measuring 122 x 87 x 93mm and weighing 577g, it’s a bit deeper front-to-back thanks to the 30x zoom lens. While the body is plastic, the grip and control layout support long shooting sessions comfortably, which is crucial given its reach.

The Olympus offers a more traditional DSLR grip and button layout, whereas the Sony mimics a DSLR's bulk to balance the heavy fixed lens. Both cameras lack weather sealing, so if you’re shooting in harsh conditions, you’ll want protective measures. In terms of portability, the E-620 edges out slightly due to smaller size but lacks the all-in-one zoom convenience of the Sony.

Control Layout and Usability: Intuitive or Clunky?

Controls can make or break how easily you adopt a camera into your workflow.

Olympus’s approach with the E-620 is classic DSLR. You get dedicated dials for shutter speed, aperture priority, exposure compensation, and a fully articulated 2.7-inch HyperCrystal LCD screen - though with a modest 230k-dot resolution by today’s standards. The optical pentamirror viewfinder covers 95% of the frame, a limitation common at this price and era, but still useful for composing wildlife or sports shots when battery life matters.

The HX100V’s SLR-like body sports a tilting 3.0-inch XtraFine LCD screen with crisp 921k-dot resolution. This makes composing and reviewing images a pleasure, especially at unusual angles. Its electronic viewfinder is handy outdoors, though somewhat limited by low resolution (typical for bridge cams of this time). Sony’s zoom rocker is ergonomically placed just beneath the shutter release, great for in-action focal length changes.

Olympus leans into manual controls more naturally with physical dials, while Sony’s reliance on menus can feel slower, especially for aperture changes or ISO adjustments. However, the Sony’s zoom makes it indispensable for situations where lens changes aren’t an option.

Breaking Down the Sensors: Size Really Does Matter

Sensor technology defines the camera’s image quality potential, impacting noise performance, dynamic range, color fidelity - basically everything.

The E-620 packs a Four Thirds-sized CMOS sensor measuring 17.3 x 13 mm, with a native resolution of 12MP. The sensor size is roughly four times larger than the HX100V's 1/2.3" BSI-CMOS sensor, which measures only 6.17 x 4.55 mm with a 16MP count. This difference is no trivial detail; it means the Olympus sensor captures significantly more light per pixel, resulting in better low-light capability, dynamic range, and color depth.

The E-620’s 12MP output (4032 x 3024) offers excellent balance between resolution and manageable file sizes, ideal for prints and professional workflows. Olympus also includes RAW capture - an absolute must for photographers who want full control over their images in post-processing.

In contrast, the HX100V does not offer RAW support, locking you into compressed JPEG files. This is expected for bridge cameras, but limits advanced editing latitude. However, it provides full HD 1080p video, which the Olympus lacks entirely.

In practical terms: If you value image quality above all - especially for portraits, landscapes, or professional uses - the Olympus sensor delivers a clearer, cleaner image with better colors and highlight detail. The Sony will struggle in shadows and high ISO scenarios but shines in versatility thanks to its zoom.

Focusing, Burst, and Shutter: Capturing the Moment

Fast and accurate autofocus (AF) and shutter responsiveness are crucial across wildlife, sports, and street photography.

The Olympus E-620 uses a 7-point AF system with both phase-detection and contrast-detection capabilities, including face detection in live view mode. Although modest by today’s standards, this hybrid AF was progressive for 2009. Continuous AF modes and selective AF area with center-weighted metering assist in tracking moderately active subjects.

Sony’s HX100V offers 9 focus points and contrast-detection AF but no phase detection. Its continuous shooting speed reaches a more impressive 10fps at full resolution - useful for freeze-framing fast sports or wildlife action, albeit with a more limited AF system that can struggle in low light or with moving subjects.

As for shutter speed, both cameras max out at 1/4000s, sufficient for general use. There’s no electronic shutter in either, so silent shooting or ultra-high-speed shooting modes aren’t options.

In my testing, the E-620’s AF feels more confident when using optimal lenses, but the HX100V’s speed and zoom, combined with quick shutter response, lets you get shots you might otherwise miss - provided lighting is good.

Portraits and Bokeh: Delicate Rendering Matters

Portrait photographers crave accurate skin tones and smooth, pleasing bokeh to make subjects pop.

The Olympus E-620’s Four Thirds sensor combined with Micro Four Thirds lens compatibility offers access to fast prime lenses (like the 45mm f/1.8) capable of creamy bokeh for professional-looking portraits. Its face detection AF ensures sharp eyes. Thanks to the larger sensor, skin tones appear natural, with a wider color gamut and better tonal gradation.

The Sony HX100V’s smaller sensor and fixed zoom lens (F2.8-5.6 aperture) limit background separation. While it can capture decent portraits at the wide end with some background blur, its smaller sensor inherently struggles to produce shallow depth-of-field effects. Face detection is absent, which can be frustrating in busy scenes.

For anyone prioritizing portraits, the Olympus is the clear winner - its sensor size, RAW support, and lens ecosystem shine. The Sony, however, offers more reach for environmental portraits where context matters.

Landscapes and Nature: Resolution, Range, and Durability

When capturing sweeping vistas or nature, resolution and dynamic range are fundamental.

The E-620’s wider sensor area and 12MP detail translate to high-quality landscape shots with excellent color fidelity. Its dynamic range score of about 10.3 EV (per DxO Mark testing) ensures highlight retention across bright skies and shadowed foregrounds - a necessity for landscape photographers.

While Olympus lacks weather sealing, its smaller, lighter body paired with interchangeable lenses makes it more versatile in the field.

Sony’s HX100V, although sporting a higher resolution of 16MP, is limited by its tiny sensor area (28 mm²). This means more noise in shadows and less tonal nuance, complicating post-processing latitude. The 30x zoom covers wide-angle to super-telephoto, useful for nature subjects both sweeping and distant. The built-in GPS supports geotagging your shots - a nice plus for landscape shooters cataloging locations.

Neither camera is weather-sealed, so consider protective housing for outdoor harsh environments.

Wildlife and Sports: Tracking and Speed Power

These genres demand speed and precision to keep up with unpredictable movement.

The Olympus E-620 offers continuous AF and a respectable 4 fps burst. Its 7 focus points are adequate for casual wildlife but may frustrate more aggressive tracking in fast sports. Its lens mount is compatible with telephoto zooms and primes that improve wildlife shooting, though at some cost to portability.

Sony’s HX100V is built for zoom reach, with its 27-810 mm equivalence (30x zoom) easily capturing distant wildlife and sports action. Shooting at 10 fps with contrast-detect AF, you can freeze moments effectively, though the AF may lag behind optical phase detection for precise subject tracking, especially in low light.

If your priority is distant subjects without swapping lenses, the Sony’s integrated lens is remarkable. For professionals or enthusiasts who prefer interchangeable optics and faster AF, Olympus is more rewarding.

Street Photography and Travel: Discretion and Versatility

Street photographers value discreet size, quick responsiveness, and portability. Travelers also seek versatile setups with good battery life.

Olympus E-620’s compact size for a DSLR, combined with low weight and articulating screen, make it surprisingly nimble. However, the optical pentamirror viewfinder can be a limitation for framing precision. The 500-shot battery life is generous, making it suitable for full-day excursions.

The Sony HX100V’s bridge style, though bulkier than a compact point-and-shoot, retains a modest footprint considering the 30x zoom. Its louder zoom and shutter mechanisms can draw attention in quiet street environments, but overall it’s manageable. Its tilting LCD is handy for candid, waist-level shooting. Battery life details are less prominent, but typical bridge cams hover between 300-400 shots.

Neither camera features touchscreen or wireless connectivity to speed social sharing, a notable omission in today’s world.

If discreet, lightweight gear with manual control is your preference, I’d point you towards the Olympus. The Sony courts travel shooters wanting an all-in-one zoom lens and GPS features, albeit at some size penalty.

Macro, Night, and Astro Photography: Close-ups and Darkness

Macro requires precise focusing and often stabilization; night and astro demand sensor sensitivity and noise control.

While neither camera offers specialized macro lenses or focus stacking, the Olympus system has access to dedicated macro lenses creating life-size magnification with better manual focus precision, thanks to its better viewfinder and lens control. Its sensor stabilization helps reduce blur in handheld close-ups.

Sony’s HX100V has a decent close focus distance enabled by the zoom lens, but without true macro magnification or RAW files, fine detail capture and editing options suffer. Its BSI CMOS sensor helps in moderately low light but noise quickly increases at high ISO.

For night or astro photography, the Olympus’s larger sensor with ISO up to 3200 and sensor-based image stabilization has an edge in image quality and flexibility. The Sony is more limited by sensor size and lens aperture, constraining long exposure or high ISO shooting capacity.

Video Capabilities: Resolution and Stabilization

Video is a major consideration for many users now.

The Olympus E-620 carries no video recording option - a significant drawback for today’s multi-use creatives, but understandable given its 2009 entry and entry-level positioning.

The Sony HX100V supports Full HD 1080p recording at 60fps, offering better motion clarity, plus lower resolution modes for slower motion or file size management. It uses optical image stabilization, which greatly improves handheld footage. However, it lacks microphone or headphone ports limiting audio control.

If video is part of your creative toolbox, the Sony is the best choice.

Professional Workflows: Reliability and File Flexibility

Pro photographers require dependability and flexibility.

The Olympus generates 12-bit RAW files compatible with nearly every major software platform, facilitating extensive manual editing workflows. The sturdy, albeit plastic, body is reliable enough for occasional field use.

Sony’s closed RAW format absence limits export options. The single card slot is standard for these models. USB 2.0 connectivity is dated in both but adequate for file transfers.

Neither camera offers rugged weatherproofing, dual storage slots, or advanced connectivity features favored in current professional bodies.
