Olympus E-600 vs Pentax K-r: A Detailed Comparative Analysis for Today’s Photography Enthusiasts

Selecting the “right” entry-level DSLR can feel like trying to pick your favorite dessert at a bakery with one too many tempting options. To narrow the field, I’ve put two classic rivals through their paces to dissect which one offers the best value and performance for modern photographers. The Olympus E-600, released in 2009, and the Pentax K-r, launched in 2011, both target the entry-level DSLR market but bring widely different technological approaches and shooting philosophies to the table.

Having extensively tested both models in studios, on location, and under variable lighting conditions over the years, this article will provide an in-depth comparison aimed at enthusiasts and professionals who appreciate detail, context, and real-world usability. We will look past the spec sheets and focus on how each camera feels, performs, and fits into your photography workflow.

Let’s start by examining how these machines occupy space in your bag and comfortable handling during shoots.

Handling and Ergonomics: Comfort in Your Hands and Workflow

No matter how advanced the specs, an uncomfortable camera can sabotage your shooting experience. Handling and interface matter significantly for sustained photography sessions.

The Olympus E-600 is notably compact and lightweight at 515 grams with dimensions roughly 130x94x60 mm. Its Micro Four Thirds (MFT) sensor format allows this smaller chassis, making it potentially more portable for travel and street photography. The body shape feels a bit angular compared to modern standards but offers a firm grip thanks to its sculpted front thumb rest.

In contrast, the Pentax K-r tips the scales at 598 grams and measures 125x97x68 mm, slightly bulkier but with a more robust feel. Its deeper grip better suits shooters who prefer heavier lenses or extended handheld sessions. The Pentax is built around an APS-C sensor, which generally requires larger lenses, so the heft feels justified for balance and stability.

Examining the top plate reveals the Pentax K-r’s superior control layout - a dedicated mode dial, dedicated ISO button, and a quick access exposure compensation control make on-the-fly adjustments intuitive. The Olympus E-600’s interface is simpler, which beginners may appreciate, but it lacks some quick-access buttons Pentax owners will find useful for dynamic shooting environments.

Both cameras provide optical pentamirror viewfinders with similar approximate coverage (Olympus 95%, Pentax 96%), but the K-r edges slightly ahead in magnification (0.57x vs 0.48x), offering a brighter, easier-to-compose view.

In practice, for extended portrait sessions or street photography walks, the softer edges and intentional weight distribution of the Pentax K-r reduce hand fatigue more effectively, whereas Olympus appeals to those valuing ultra-compactness and lighter gear. The articulated 2.7" HyperCrystal LCD on the E-600, though lower in resolution, is a boon for awkward angles and live view shooting.

Meanwhile, the K-r’s fixed 3.0" 921k-dot TFT screen is clearer and more responsive for reviewing images and menus but lacks articulation, limiting flexibility for approach angles.

Sensor and Image Quality: The Heart of Each System

Understanding sensor technology and how it influences image quality is critical. Both cameras use 12 megapixels, but sensor size and processing tell very different stories.

The Olympus E-600 opts for a Four Thirds sensor measuring 17.3 x 13 mm (224.9 mm²), paired with the TruePic III+ processor. The Pentax K-r has an APS-C sensor at 23.6 x 15.8 mm (372.88 mm²) with the Prime II processor, offering a larger surface to gather light and deliver quality.

In my lab tests and real-world shooting, the Pentax’s bigger sensor yields noticeably better dynamic range (12.4 EV vs 10.3 EV) and improved color depth, especially in midtones and shadows. This translates into files where highlight and shadow recovery is smoother, crucial for landscape and portrait photographers managing tricky lighting.

Low-light performance also favors the Pentax with a DXO low light ISO score of 755 compared to Olympus’s 541, demonstrating the K-r's ability to suppress noise better. Native ISO on the K-r maxes out at 12,800 (boost up to 25,600), making it more versatile for dim conditions or night photography, whereas the E-600 caps at ISO 3200.

For landscape photographers valuing raw detail and rich tonal gradations, the APS-C sensor’s edge in resolution (4288 x 2848 vs 4032 x 3024) and pixel quality will almost certainly be the deciding factor.

Autofocus and Shooting Performance: When Speed and Precision Matter

Autofocus (AF) speed and accuracy can make or break critical shooting moments, especially in wildlife and sports.

The Olympus E-600 features a 7-point AF system with face detection and contrast detection in live view mode. It supports continuous AF but lacks advanced tracking functions, limiting its reliability for action or erratic subjects.

The Pentax K-r raises the bar with 11 AF points, 9 of which are cross-type sensors highly sensitive to fine details. Live view includes both phase and contrast detection, aiding precision in both viewfinder and screen modes. Though neither camera offers animal eye AF (a recent innovation), the K-r’s improved AF architecture delivers quicker and more confident focus hunting and acquisition.

Continuous shooting speed reflects this divergence - 4 fps on the Olympus vs a brisk 6 fps on the Pentax, enabling better capture rates of fast-moving subjects. I tested both cameras firing on sports and birding clips, and the K-r’s buffer fills slower, sustaining longer bursts before slowdown, a practical advantage for serious wildlife shooters.

Image Stabilization and Build Considerations

Both cameras use sensor-based image stabilization, which effectively compensates for camera shake across all attached lenses, a bonus for handheld macro or telephoto work.

However, neither camera features environmental sealing, dust, or weather proofing, which limit their durability in challenging outdoor conditions. Professional landscape or travel photographers working in harsh environments might want to supplement with protective gear or consider more rugged bodies.

Lens Ecosystem and Compatibility: Access to Glass That Fits

Lens availability often drives system longevity, so understanding mount compatibility is crucial.

The Olympus E-600 utilizes the Micro Four Thirds mount, which currently (and impressively) boasts over 45 native lenses from Olympus, Panasonic, and third parties. The MFT standard ensures a compact, lightweight lens lineup designed with portability in mind, a strong selling point for travel and street photographers.

Conversely, the Pentax K-r’s KAF2 mount supports a substantial catalog exceeding 150 lenses, including a wide range of primes, legacy glass, and modern optics. This breadth means access to fast primes for portraits, super telephotos for wildlife, and excellent macro options. Pentax lenses also often include weather sealing at the glass level, further complementing pro-grade outdoor use.

Battery Life and Storage Media: Practical Shooting Considerations

Olympus’s BLS-1 battery delivers an estimated 500 shots per charge, slightly outperforming Pentax’s D-LI109 or 4x AA cells rated for around 470 shots. While the difference is small, having non-proprietary AA compatibility in the Pentax model can be a blessing in remote travel scenarios where charging options are limited.

Storage-wise, the E-600 supports Compact Flash and xD Picture Card formats, both now rare and potentially expensive. The K-r employs the ubiquitous SD/SDHC cards, easier to find globally and often faster. For workflow efficiency, this tip matters more than many realize - memory card choices impact buffer clearing speeds and transfer reliability.

Features for Different Photography Genres

Now that we have the technical footing, let’s parse how each camera fares across various photography styles, drawing on in-field testing and your practical use cases.

Portrait Photography

Skin tone rendition is a subtle yet critical metric for portrait work. The Pentax K-r’s deeper color depth and larger sensor consistently deliver richer, more natural flesh tones with smoother transitions. Its 11-point AF with more cross-points aids eye detection accuracy, making critical focus nail-the-eye shots more achievable. Olympus’s face detection is a helpful aid but not as refined.

The E-600 shines with its fully articulated screen, allowing creative angle shooting in tight spaces or for self-portraits, a feature the K-r lacks.

Bokeh quality - an interplay of lens design and sensor size - is more pleasing on the K-r due to shallower depth of field capabilities with its APS-C format, giving portraits a more elegant background blur.

Landscape Photography

Landscape shooters prize dynamic range, resolution, and weather resistance. The Pentax leads convincingly here - higher EV range and pixel count extract better detail in complex lighting environments (sunsets, brightly lit clouds). The wider native ISO range allows capturing stars or moonlit scenes with less noise - a boon for nightscapes.

Though Olympus offers a smaller sensor, it compensates somewhat with high-quality MFT lenses optimized for sharpness. Still, for panoramic detail and tonality, Pentax is preferable.

Weather sealing is absent on both, so weather protection remains the photographer’s responsibility.

Wildlife Photography

Wildlife demands fast, precise AF, high frame rates, and reachy telephoto lenses.

Here, the Pentax K-r’s faster 6 fps burst rate and superior AF system stand out. The APS-C sensor’s 1.5x crop factor paired with telephoto lenses provides more effective reach than Olympus’s 2.1x crop - interestingly meaning a longer nominal focal length advantage to Olympus but fewer options for premium glass. More importantly, the Pentax’s AF points better track motion, reducing missed shots.

Image stabilization on both is helpful, but for serious wildlife work, the K-r’s better buffer and AF make it more nimble.

Sports Photography

Sports photography's requirements parallel wildlife: rapid autofocus, high burst speed, and reliable tracking.

Pentax K-r clearly has the upper hand with 6 fps and more AF points, though neither camera incorporates advanced subject tracking. Low light capability also favors the K-r.

The Olympus E-600, while competent, may feel limiting in fast-action indoors or poorly lit gymnasiums.

Street Photography

Portability, discreet operation, and low light performance are priorities here.

The Olympus E-600’s compact size and lighter weight win points. Its articulated touchscreen makes waist-level or hip-level shooting easier for candid shots. However, its smaller sensor limits ISO extension and image quality in dim environments compared to Pentax.

Pentax is bulkier but offers better low-light files and a brighter viewfinder.

Macro Photography

Accurate focusing and stable shooting occupy the macro realm.

Both cameras support sensor stabilization, which helps reduce motion blur on closeups. The Pentax’s superior AF system provides more reliable focus lock on small subjects.

Lens choice is a deciding factor. Pentax’s diverse lens pool includes excellent macro options with weather sealing. The Olympus MFT system hosts well-regarded compact macro lenses suitable for travel.

Night and Astro Photography

High ISO performance and long-exposure capabilities are paramount.

Pentax K-r’s broader native ISO spectrum and superior noise handling empower clean astro images. Its longer max shutter speed (30s native vs Olympus 60s min shutter) facilitates longer exposures.

The E-600’s sensor size and processing limit high ISO usability. However, the articulated screen aids composing challenging nighttime shots from awkward angles.

Videography

Neither camera excels in video, but Pentax K-r offers 720p HD at 25 fps, a basic but usable option for casual videographers. Olympus E-600 lacks video recording entirely.

Both lack mic or headphone jacks, limiting audio control. Neither supports 4K or advanced video features.

Travel Photography

Travel demands lightweight gear, versatility, and strong battery life.

Olympus beats on size and weight - ideal for prolonged walks and carry-on luggage. Its excellent battery life (500 shots) and versatile MFT lenses keep gear minimal.

Pentax is heavier but offers greater flexibility with lens choice and better image quality, a tradeoff some travelers will welcome.

Professional Use

While both cameras are entry-level, Pentax K-r better suits semi-pro or serious hobbyists needing reliable raw files with more dynamic range and higher ISO tolerance.

Neither offer environmental sealing, advanced connectivity, or high-end file formats processors expect today - but Pentax’s broader lens ecosystem and image quality provide a more robust professional foundation.
