Olympus E-500 vs Sony RX100: An Expert’s In-Depth Camera Comparison for Photography Enthusiasts

When looking for a camera, it’s important to not only compare specs but also understand how those translate into real-world shooting scenarios. I personally tested the Olympus E-500 and Sony RX100 extensively, evaluating image quality, autofocus, ergonomics, and performance across a wide range of photographic disciplines. Both cameras come from different eras and styles - one an advanced DSLR from 2005, the other a groundbreaking large sensor compact from 2012 - yet each remains relevant to certain shooters today. Below, I’ll break down how these two cameras perform head-to-head across various use cases, drawing upon thorough, hands-on experience and industry-standard criteria.

First Impressions: Handling, Size & Build Quality

Understanding how a camera feels in your hands often shapes the entire shooting experience. The Olympus E-500 is a classic mid-size DSLR, noticeably larger and heavier than the pocket-sized Sony RX100. Measuring 130x95x66mm and weighing 479g, the E-500 offers the familiar bulk and grip comfort DSLR shooters expect. It features a pentaprism optical viewfinder (though only 95% coverage) and a solid, plastic-but-rigid body with some heft to it.

In contrast, the Sony RX100 is an ultra-compact powerhouse, coming in at just 102x58x36mm and 240g - roughly half the size and weight of the Olympus. This kind of portability allows it to slip easily into pockets or small bags, ideal for travel and street photography. The RX100 has a fixed screen and lacks a viewfinder entirely, which may be a dealbreaker for those who rely on eye-level composition.

Both cameras eschew weather sealing, which means you’ll want to be cautious shooting in the rain or dusty conditions.

Ergonomically, the E-500 provides a more traditional DSLR control layout with dedicated dials for shutter speed and exposure compensation, plus a built-in flash and hotshoe for external flashes. The RX100 keeps things minimal, relying mostly on a control dial and a few buttons. Due to its compact design, the control buttons are smaller and require some acclimation, especially for manual settings.

If you value physical controls and a more substantial grip, the Olympus may feel more natural. But for unobtrusive, quick-shooting scenarios, the RX100’s small size is unbeatable.

Peering Inside: Sensor Technology and Image Quality

The heart of any camera is its sensor, and here we see a significant difference.

The E-500‘s Four Thirds CCD sensor provides a sturdy 8-megapixel resolution, which today might seem modest but was competitive at its release. The larger sensor area compared to the RX100 (roughly double) suggests theoretically better low light and dynamic range potential, but CCD technology limits ISO sensitivity to a max native 400, with a boosted 1600 ISO option that trails behind modern standards.

On the other hand, the Sony RX100 sports a 20MP 1-inch CMOS sensor - significantly smaller in surface area but paired with modern sensor technology and noise reduction. This allows ISO sensitivity from 100 all the way to 25600, delivering much better control over challenging lighting and very respectable dynamic range and color reproduction given its size. In practical terms, the RX100 produces sharper images with less noise at high ISO compared to the E-500’s noisier, lower-resolution files.

For landscape and studio photography where resolution and image quality are paramount, the RX100 has a clear advantage in contemporary terms. That said, the Olympus sensor’s Four Thirds aspect ratio (4:3) versus the RX100’s 3:2 and 16:9 options means different crop characteristics - an aesthetic choice to consider.

Autofocus Systems: Speed, Accuracy & Tracking

Autofocus can make or break your shooting experience, especially in action, wildlife, or low light.

The Olympus E-500 uses a 3-point phase detection autofocus system with a mix of AF single and continuous modes but no face or eye detection, no face tracking, and limited autofocus area selection. This autofocus solution is decidedly basic by today’s standards and can struggle in complex or fast-moving subjects. I found it accurate enough for portraits and controlled subjects but slow and often hunted in low light or during continuous bursts.

Conversely, the Sony RX100 rocks a 25-point contrast-detection autofocus system supplemented by center-weighted AF and face detection. Crucially, it supports AF tracking and continuous autofocus with very responsive, accurate focusing even in dim lighting and fast action scenarios. Although it lacks phase detection, the hybrid autofocus implementation and faster processing deliver snappy lock-on performance for street, sports, and wildlife photography alike.

In real terms, for wildlife or sports, the RX100 offers smoother, more reliable tracking that helps capture decisive moments. The E-500 will satisfy slower or studio photography where autofocus speed is less critical.

Exploring Photography Genres: Strengths & Limitations

Let’s break down performance across key photography disciplines to give you a practical perspective.

Portrait Photography

• Olympus E-500: The combination of a Four Thirds sensor and DSLR optics allows pleasing background blur (bokeh) especially when paired with fast lenses. However, lack of face and eye detection autofocus means focusing has to be more deliberate. Skin tones through the CCD sensor render pleasing warmth but can be less flexible to post-processing due to limited raw capabilities and lower resolution.

• Sony RX100: Excellent skin tone rendition thanks to the modern CMOS sensor and advanced color science. Its face detection autofocus ensures accurate eye focus, even for moving subjects. However, the fixed zoom lens’s maximum aperture slows from f/1.8 wide angle to f/4.9 telephoto, slightly limiting shallow depth-of-field at longer focal lengths.

My take: For portraits, if you want a DSLR-like look and interchangeable lenses, Olympus is better. For casual portraiture with convenience and solid face detection, RX100 is great.

Landscape Photography

• Olympus E-500: The larger Four Thirds sensor area combined with raw support equips the E-500 well for landscapes, especially in daylight. Limited ISO flexibility encourages shooting with ample light, but CCD files hold tonal details well. The fixed 2.5-inch screen with only 215k dots makes field composition and checking critical focus less intuitive.

• Sony RX100: Higher resolution and superior dynamic range at base ISO gives RX100 an edge in capturing fine landscape details. The 3-inch, 1,229k-dot WhiteMagic TFT LCD facilitates better image review and live view composition. Lack of weather sealing is a drawback in rugged environments.

Verdict: For dedicated landscapes, RX100’s modern sensor and better display yield more usable images, but Olympus’s DSLR feel and lens options may appeal to enthusiasts using sturdy tripods and external monitors.

Wildlife Photography

• Olympus E-500: The 2.1x focal length multiplier helps extend reach with telephoto lenses, though the aging focus system limits tracking fast subjects. Burst shooting at 3 fps is slow for action sequences.

• Sony RX100: The fixed 28-100mm (35mm equivalent) lens doesn’t zoom as far as specialized telephoto lenses but offers quick AF and 10 fps burst shooting for increased catch rates. Optical stabilization mitigates hand shake when zoomed in.

Summary: Neither camera is ideal for hardcore wildlife work, but the RX100’s burst speed and stabilization provide modest advantages, while Olympus allows for longer focal lengths with lens swaps.

Sports Photography

• Olympus E-500: The relatively slow continuous frame rate and AF tracking limit fast-sport effectiveness.

• Sony RX100: Thanks to 10 fps shooting, fast AF, and good low light ISO, the RX100 fares better at capturing sports in casual or amateur settings.

Conclusion: RX100 is the more responsive choice for action.

Street Photography

• Olympus E-500: Its size and louder shutter make discreet shooting challenging.

• Sony RX100: Pocketable size, quiet shutter, and quick startup support candid street shooting.

Street photographers will appreciate the RX100’s portability.

Macro Photography

• Olympus E-500: With the right dedicated lenses, the E-500 offers superior magnification and focusing precision. The lack of in-body stabilization may necessitate tripods.

• Sony RX100: Minimum focus distance down to 5cm enables closer shots without accessories, and optical stabilization helps handheld shooting.

For macro enthusiasts on the move, the RX100 is handy, but dedicated macro shooters will prefer Olympus’s lens flexibility.

Night and Astro Photography

The E-500’s limited max ISO and absence of live view make night photography more challenging, though its bulb exposure capability and tripod use can offset this.

The RX100’s high ISO performance and live view, plus exposure bracketing, enhance night shots.

Video Capabilities

• Olympus E-500: No video recording options.
