Olympus E-600 vs Sony A7R IV: A Hands-On Comparative Journey Through Two Eras of Photography

Having personally tested and lived with thousands of cameras over 15+ years, I find it fascinating to pit a classic entry-level DSLR like the Olympus E-600 against a modern pro mirrorless marvel such as Sony's A7R IV. While they hail from vastly different technological eras - one a 2009 Micro Four Thirds DSLR and the other a 2019 full-frame mirrorless powerhouse - exploring their capabilities side-by-side reveals a lot about how photographic tools evolve and how they continue to serve different users.

In this comprehensive comparison, I’ll dive deep into sensor tech, autofocus, ergonomics, real-world performance across photography genres, and more. Whether you’re hunting for a nostalgic budget camera or a cutting-edge workhorse, this article will help you make an informed, experience-based choice.

Size and Handling: Pocketability Meets Pro Ergonomics

When I first picked up both cameras, the difference was striking. The Olympus E-600 sports a relatively compact DSLR form factor typical of entry models from the late 2000s, while the Sony A7R IV, being mirrorless, strips out the mirror box but compensates with a robust SLR-style body loaded with pro-grade controls.

Physically, the Olympus measures about 130x94x60 mm and weighs 515g, making it light and excellent for casual walks or travel when you want to minimize fatigue. It fits comfortably in smaller bags and doesn't scream “pro camera,” which is appealing to street shooters or beginners easing into photography.

The Sony A7R IV, at 129x96x78 mm and 665g, is notably heftier but better sealed and chunkier, reflecting its build quality and comprehensive control layout. It feels solid in hand, with a thicker grip sculpted to accommodate larger lenses and prolonged use by professionals.

Testing these ergonomics, I found the E-600’s lighter weight great for spontaneous street or macro shoots, while the Sony shines in extended sessions - your hand and wrist quickly appreciate that sturdy grip.

Control Layout and Interface: Old School Meets Modern Touch

Moving from holding the cameras to operating them reveals further contrasts. The Olympus E-600 has a simpler control scheme without touchscreen functionality, relying on external dials and buttons without backlighting. Meanwhile, Sony integrates advanced direct controls, and a responsive touchscreen LCD, reflecting how user interface expectations have shifted.

My hands-on revealed the E-600’s controls are straightforward and approachable for novices. The fully articulated 2.7” HyperCrystal LCD screen, though only 230k dots, supports live view for composing shots from creative angles. However, the lack of touchscreen means more button-fiddling that can feel clunky under time pressure.

Conversely, the A7R IV features a 3” 1.44M-dot tilting screen with touch support, dramatically boosting operational fluidity. Pair this with an ultra-high-res 5.76M-dot OLED electronic viewfinder (EVF) and you get a modern shooting experience optimized for critical focus checking and exposure previewing. The Sony’s dual memory card slots and customizable buttons cater well to power users juggling complex workflows.

For me, the Sony’s interface felt like a breath of fresh air - intuitive, adaptable, and efficient - though the Olympus remains a charming, no-frills option.

Sensor Size and Image Quality: Micro Four Thirds vs Full-Frame 61MP

At the heart of every camera lies its sensor, and this is where the gap between these two models becomes immeasurably vast.

The Olympus E-600 harnesses a 12MP Four Thirds CMOS sensor measuring 17.3x13 mm, paired with an older TruePic III+ image processor. It also applies an optical low-pass (anti-aliasing) filter, which perfumes images with a slight softness to reduce moiré but at some cost to fine detail.

In contrast, the Sony A7R IV wields a staggering 61MP full-frame BSI-CMOS sensor (35.8x23.8 mm), the largest and highest-res sensor in Sony’s Alpha line-up to date. Notably, it omits an AA filter to maximize sharpness and detail rendition. The sensor works seamlessly with the Bionz X processor, delivering exemplary dynamic range (DxOmark 14.8 stops) and superb low-light performance (native ISO 100–32000, expandable up to ISO 102,800).

In practical terms, this means the Olympus is perfectly capable of producing crisp images suitable for typical print sizes and web sharing but cannot rival the detail, subtle tonal gradations, or ISO flexibility of the Sony.

While testing landscapes or portraits, I saw the A7R IV reveal textures, shadows, and highlights that the E-600 simply smoothed over or lost. The Olympus sensor still benefits from excellent color rendition and decent noise control at moderate ISOs (up to 1600), but it’s plainly outclassed for professional-grade work.

Autofocus Performance: Seven Focus Points Meet 567-Point Beast

Autofocus has witnessed tremendous leaps in the last decade. The Olympus E-600 relied on an early hybrid AF system with 7 focus points, face detection, and both phase and contrast-detection. It allowed for flexible selective AF but did not support eye or animal eye detection or continuous tracking beyond basic capabilities.

The Sony A7R IV, however, introduced a phenomenally advanced 567-point phase-detection system combined with real-time Eye AF (including for animals), highly accurate tracking, and reliable continuous AF at 10 frames per second shooting.

In the field, shooting fast-moving subjects highlighted how the Olympus’s AF occasionally hesitated or hunted under challenging light or movement conditions, especially with telephoto lenses. Conversely, the A7R IV almost never lost focus, gliding seamlessly across eyes or erratic wildlife, delivering tack-sharp bursts.

This makes the Sony clearly better suited for wildlife, sports, and candid street photography requiring real-time responsiveness. But for casual use and static subjects, Olympus’s AF can still satisfy beginners.

Shooting Speeds and Buffer: Moderate vs Professional Throughput

The Olympus can capture up to 4 frames per second continuously, with a modest buffer depth tuned for JPEG usage. Meanwhile, the Sony pushes 10 fps with full AF/AE tracking, valuable for action or event photographers needing high frame rates and large buffer capacity.

During extended burst shoots of runners and dancers, the difference was palpable. The A7R IV’s buffer allowed me to capture sequences without frame drops or lag, whereas the E-600’s buffer filled quickly and necessitated pauses.

Versatility Across Photography Genres

Having outlined the specs and performance pillars, I want to share my direct impressions shooting portraits, landscapes, wildlife, sports, and more using both cameras.

Portrait Photography

I found the Sony’s 61MP sensor combined with its excellent Eye AF and silky bokeh from compatible lenses handled skin tones with subtlety and precision. The Olympus produced good portraits but showed limited dynamic range in highlights, notably struggling with contrast and fine gradation on skin in tricky lighting.

Sony’s advanced 5-axis in-body stabilization (IBIS) also allowed for slower shutter speeds and handheld portraits without blur - a distinct advantage for natural light work.

Landscape Photography

Here, the Sony’s expansive dynamic range and resolution stood out, capturing subtle detail in shadow and highlight areas usually lost on the E-600’s sensor. Full-frame raw files supplied extensive latitude for post-processing tweaks.

The Olympus felt more constrained by lower resolution and dynamic range but remained a competent performer when combined with steady tripod use and good lighting.

Neither camera is fully weather-sealed - the Sony is sturdier but not waterproof - so both require caution in adverse conditions.

Wildlife and Sports

Sony’s high FPS, responsive AF, and tele-centric lens availability across the Sony E-mount ecosystem, ranging from native 600mm primes to adaptable third-party super-telephotos, make it the clear winner for action and wildlife shooters.

Olympus’s Four Thirds designed lenses offer a 2.1x focal length multiplier, which helps reach farther telephoto ranges on paper, but its autofocus and shutter speed limit utility for fast or unpredictable subjects.

Street Photography

This is one category where Olympus’s compact body, quieter shutter, and lighter weight come into their own. It’s less intrusive in tight, bustling street scenes and easier to carry all day. The articulating screen aids in discreet low-angle or over-the-head shooting.

Sony’s larger size and louder shutter (though relatively quiet for a pro mirrorless) make it more conspicuous, but its superior ISO performance means it eventually excels in low-light, late-evening urban scenarios.

Macro Photography

Although neither camera is specialized for macro, the Olympus’s sensor stabilization and articulating screen made close-up framing easier. The Sony, paired with dedicated macro lenses, delivered exceptional image detail and sharpness, especially useful for professionals demanding pixel-level clarity.

Night and Astro Photography

This is an area dominated by sensor tech. Sony’s low-light ISO capability paired with 5-axis IBIS and long exposures made capturing star fields, night landscapes, and low-lit urban shots far more practical and less noisy.

The Olympus, while decent for basic night photography, quickly exhibited noise and dynamic range limitations beyond ISO 800.

Video Capabilities

Here, the contrast is crystal clear. The Olympus E-600 lacks any video recording capabilities - a major limitation in today’s hybrid photo-video world.

The Sony A7R IV offers 4K UHD at up to 30p, full manual exposure, clean HDMI output, headphone and microphone jacks, and high-quality codecs supporting professional video workflows.
