Comparing Olympus E-600 and Sony A55: Two Entry-Level DSLRs from a Decade Ago, Revisited with Today’s Expertise

Selecting the right entry-level DSLR camera can be a daunting journey, especially when looking back at models introduced over a decade ago. I recently spent extensive time testing and comparing the Olympus E-600 (2009) and Sony SLT-A55 (2010) - two iconic models in the entry-level DSLR space of their day - to determine how their specifications and real-world performance stack up even now. While neither are current models, understanding their strengths and weaknesses through a technical lens reveals timeless lessons for photographers exploring legacy gear or vintage cameras as affordable options.

In this 2,500-word review, I’ll break down all critical aspects - from sensor architecture and autofocus performance to ergonomics, image quality, and usability - grounded firmly in practical experience. Throughout, I’ll embed direct image comparisons and hands-on insights to help you decide which camera might be a better fit for your creative goals.

Let’s dive in!

Putting Their Physical Presence into Perspective: Size, Feel, and Ergonomics

Before you even hit the shutter button, the camera’s design dictates much about your shooting experience - from comfort during extended use to intuitive control access. To start, let’s examine their silhouettes and handling.

The Olympus E-600 and Sony A55 share a compact SLR body type, but a closer look reveals different design philosophies. The E-600 is a bit smaller and slightly boxier with measurements of 130×94×60 mm weighing about 515 grams including the battery. The A55, by comparison, measures 124×92×85 mm and sits around 500 grams, making it marginally lighter but with a chunkier grip area. I found that the E-600’s modest grip caters well to smaller hands, but the Sony’s sculpted grip offers a more secure hold during longer sessions or telephoto use.

Both cameras feature fully articulated LCD screens, which is beneficial for varied shooting angles and video framing (though more on video capabilities later). The Sony’s 3-inch screen is larger and boasts higher resolution (921k dots versus Olympus’ 2.7-inch, 230k), a crucial advantage in critical focus confirmation and menu navigation.

Looking around their top plates, the control layouts vary as well. The Olympus favors simplicity but includes all essential dials and buttons within easy reach. In contrast, the Sony integrates specialized controls like a mode dial with advanced settings - reflecting its somewhat more ambitious target audience. In overall use, I felt the Sony’s user interface was more advanced but could feel cluttered to complete beginners.

For travelers and street photographers, both cameras’ moderate size and weight make them rather portable. Yet, ergonomically, I often favored the Sony A55 when wielding longer lenses or shooting in active scenarios, thanks to its grippy design and slightly better button placement for one-handed operation.

The Heart of the Image: Sensors and Image Quality

In the modern era, sensor technology is king. How an entry-level DSLR performs in real-world image quality hinges largely on its sensor size, resolution, and integration with image processors.

The E-600 employs a Four Thirds CMOS sensor measuring 17.3×13 mm, delivering 12 megapixels of resolution. While its sensor area (~225 mm²) is respectable, it’s notably smaller than the A55’s APS-C CMOS sensor at 23.5×15.6 mm (~367 mm²), which offers a 16 MP resolution. This size difference translates to significant impacts on depth of field control, noise levels, and dynamic range.

The Olympus’s TruePic III+ image processor complements the sensor architecture but by today’s standards is somewhat limiting, particularly at high ISOs. The Sony’s Bionz processor, meanwhile, is known for strong noise reduction with minimal detail loss, providing the A55 with a distinct advantage in low-light conditions.

In testing, the Olympus E-600 produces sharp and well-exposed daylight images, though with noticeable falloff in highlight retention in challenging contrast scenarios. The Sony, on the other hand, demonstrates superior dynamic range, holding more shadow and highlight detail - a boon for landscape and outdoor photographers aiming for maximum tonal depth.

Color depth, as measured in bits, is about 21.5 on the E-600 versus 23 for the A55, a subtle but meaningful difference for preserving color gradations in portrait and nature photography. Low-light ISO scores also differ dramatically, with the Olympus maxing out at ISO 3200 effectively, and the Sony pushing to ISO 12800 natively with usable results even beyond.

If absolute image quality is your priority - especially for prints and professional use - the Sony A55 clearly has a technological edge, thanks largely to its larger sensor and more modern processing engine.

Viewing Your Shots: Screens and Viewfinders in Use

Composing and reviewing images is one of the top interaction points with a camera. Both models offer articulation and live preview, but their designs diverge substantially.

The E-600’s smaller 2.7-inch screen with 230k-dot resolution is serviceable but can struggle under bright daylight or when scrutinizing critical focus - something I noticed when checking sharpness in macro shots or portraits. The Sony’s 3-inch, 921k dot LCD is vivid, bright, and crisp, making it easier to evaluate images on the spot and scroll through menus or playback modes.

The Olympus provides an optical pentamirror viewfinder with approximately 95% coverage and a 0.48× magnification. It’s a fundamental DSLR experience but feels limited for precise framing, especially given the smaller magnification and incomplete frame coverage.

Conversely, the Sony A55 departs from tradition by using an electronic viewfinder (EVF) with an impressive 1150k-dot resolution and 100% coverage. This higher magnification (0.73×) combined with real-time exposure preview benefits photographers wanting accurate framing and instant image effect feedback - a distinct advantage in fast-paced environments like sports or events.

While the EVF has minimal lag and excellent brightness, some purists may still prefer the optical clarity of the Olympus’s pentamirror, especially in very bright outdoor shooting. However, the Sony’s clear advantage here is undeniable and showcases how SLT technology was pioneering EVFs in consumer DSLRs.

Autofocus Systems: Speed, Accuracy, and Flexibility

There’s more to a camera’s AF than just numbers. Speed and accuracy can make or break shots of moving subjects or candid moments. As someone who has logged long hours meticulously testing focusing systems, it’s clear these two cameras represent differing AF philosophies.

The Olympus E-600 offers 7 autofocus points using a hybrid AF system combining phase and contrast detection. While basic, it includes face detection for improved portrait accuracy. Live view AF performance is moderate but lagging behind newer generation models, which is expected in an older entry-level DSLR.

The Sony's prowess is evident with 15 autofocus points (3 cross-type), based on phase detection through its translucent mirror technology (SLT). This system employs continuous AF in both stills and video, allowing 10 fps burst shooting without focus loss - a significant leap, especially for sports and wildlife enthusiasts needing persistent subject tracking.

Practical testing revealed the E-600’s AF system performing adequately in controlled lighting but occasionally hunting in low light or complex focus scenarios. The Sony A55’s AF was noticeably faster and more reliable, locking focus nearly instantaneously in daylight and maintaining it well in dimmer conditions - a critical advantage for action shooters.

Despite neither model offering advanced animal eye AF or AI tracking (common today), the Sony’s more sophisticated arrangement lends it a distinct performance margin in autofocus-dependent genres.

Durability and Weather Resistance: Can They Take a Beating?

Both cameras sit outside the professional, weather-sealed ecosystem. Neither offers official environmental sealing, waterproofing, nor ruggedized PM protections. This is typical for consumer/prosumer DSLRs of their era.

While the Olympus E-600 weighs just 515g and the Sony 500g, both require cautious handling in challenging shooting conditions - rain, dust, or heavy shock. Their plastic build and compact SLR style allow for light portability but attract fingerprints and minor wear.

So, if you expect to shoot outdoors in unpredictable environments or rugged landscapes regularly, these cameras will need optional protective solutions or careful operating conditions.

Lenses and System Ecosystem: What Glass Works Best?

The E-600 relies on the Micro Four Thirds mount with 45 lenses available at launch, emphasizing compactness but with a 2.1x crop factor - meaning telephoto lenses reach substantial effective focal lengths, but wide-angle architecture is more challenging.

The Sony A55 utilizes the Sony/Minolta Alpha mount with access to 143 lenses at announcement. The 1.5x crop factor places it between Four Thirds and full-frame systems, offering superior wide-angle flexibility and an expansive lineup of legacy glass, including many fast primes and high-quality zooms.

In my hands-on experience, Sony’s lens ecosystem - bolstered by compatibility with Minolta AF lenses - allows more creative versatility across genres, especially for portrait, landscape, and sports shooters seeking long or fast glass.

Olympus’s kit lenses are compact and optically sharp but less versatile for professional-grade telephoto or ultra-wide needs.

Burst Rates and Buffer Depth for Action Photography

If you’re a sports or wildlife shooter, continuous burst performance is fundamental.

The Olympus E-600 tops out at 4 fps, modest but acceptable for casual active shots. The Sony A55 pushes strong at 10 fps, a remarkable figure at this price and vintage period made possible by its translucent mirror design allowing faster readout.

In real-life testing, the Sony consistently captured action sequences smoothly with no significant buffer slowdowns in JPEG mode, while the Olympus occasionally experienced lag during high-speed shooting.

Video Capabilities: More than a Still Camera

While DSLRs from 2009-2010 were only starting their video journeys, the Sony A55 dramatically outclasses the Olympus here.

The E-600 lacks any video recording capability, limiting its appeal to still photographers only.

By contrast, the Sony A55 incorporates 1080p Full HD video recording at 60 and 30 fps with AVCHD and MPEG-4 support - impressive for the era. It also features continuous autofocus in movie mode, a microphone input jack, and HDMI output for external monitors.

For hybrid shooters and vloggers exploring vintage gear, the A55 remains a rare combination of affordable DSLR stills with competent video features. Olympus users would need a separate video camera or a more modern mirrorless body for movie capture.

Battery Life and Storage Media

Both cameras are fueled by removable proprietary rechargeable batteries - Olympus BLS-1 and Sony NP-FW50 - the latter still in use on several recent Sony models, highlighting its enduring design.

Olympus advertises approx 500 shots per charge, a solid figure for mirrorless and DSLRs of that time. Sony’s rating stands at about 380 shots, likely impacted by the power demands of the electronic viewfinder and video functions.

Regarding storage, the Olympus E-600 uniquely offers dual storage formats: Compact Flash and xD Picture Card slots. This flexibility was forward-thinking for 2009 but xD cards are now obsolete.

Sony standardizes on SD card formats and Sony Memory Stick variants - more ubiquitous and currently widespread, making SD the practical choice.

Connectivity, Extras, and Noteworthy Features

Neither camera boasts Bluetooth or Wi-Fi, standard for cameras of their generation. However, the Sony A55 does include built-in GPS - a surprisingly advanced feature for 2010, useful for geotagging your images in travel or wildlife work.

USB 2.0 data transfer is present on both, with Sony offering HDMI out for easy display on HDTVs - an advantage for reviewing stills or movies.

The electronic shutter speeds and silent shooting modes are absent on both, keeping operation traditional but reliable.
