Olympus E-600 vs Pentax K100D Super: A Hands-On Comparison of Entry-Level DSLRs from the Late 2000s

As someone who has spent thousands of hours testing digital cameras across every imaginable genre, I’m always intrigued by what classic DSLRs brought to the table over a decade ago - especially in the competitive entry-level segment. Today, I put the Olympus E-600 and Pentax K100D Super head-to-head. Both announced around the same time (2007–2009), these compact SLRs reveal very different philosophies and technical foundations, each with unique pros and cons.

If you’re a photography enthusiast or professional researching legacy gear for budget or niche applications - say, starting film-like manual focusing skills or building a second camera system - this detailed comparison will guide you through the ins and outs of these cameras. I’ve personally handled and tested both extensively, scrutinizing everything from sensor tech and autofocus to handling ergonomics and real-world image performance.

Let’s dive in.

First Impressions: Size, Handling, and Ergonomics

When assessing any camera, the tactile experience - and physical footprint - are crucial to overall usability and shooting comfort. The Olympus E-600 and Pentax K100D Super both embrace a traditional compact SLR design tailored to beginners, but their approach to ergonomics noticeably differs.

The Olympus E-600 weighs 515g and measures 130×94×60mm, making it slightly more compact and lighter than the Pentax K100D S, which tips scales at 646g and measures 129×91×71mm. The E-600’s slimmer profile and slightly shorter grip depth make it more pocketable in smaller camera bags or backpacks - a definite plus for travel or street shooters prioritizing portability.

Controls-wise, the Olympus features a fully articulated 2.7" HyperCrystal LCD screen, which offers an edge for creative framing and macro work from tricky angles. The Pentax sticks with a fixed 2.5" LCD, slightly smaller and less flexible, though it perks up with a top status LCD – useful for quick glance settings checks without looking at the main screen.

The E-600’s pentamirror optical viewfinder covers 95% of the frame with 0.48x magnification, while the Pentax offers marginally better 96% coverage with 0.57x magnification. I found myself slightly favoring the Pentax viewfinder for its clearer and more immersive view.

On the top deck, Olympus’s design is straightforward with clearly marked dials and a drive mode switch. Pentax’s top LCD complements essential exposure info but may feel dated compared to more modern controls. Neither is weather-sealed, unsurprising at this price point and release era.

Ergonomic takeaway: Olympus’s compactness and articulation champion usability for travel and macro photography, while Pentax’s slightly larger grip and viewfinder extend comfort during long portrait or landscape sessions.

The Heart of the Matter: Sensor and Image Quality Analysis

At the core of any camera is its image sensor and processing pipeline. Here, the Olympus E-600 and Pentax K100D Super take fundamentally different technical paths, which greatly influence image characteristics and application suitability.

The Olympus E-600 uses a 12MP Four Thirds CMOS sensor measuring 17.3×13 mm, while the Pentax K100D Super features a 6MP APS-C CCD sensor and a larger 23.5×15.7 mm area. Despite Olympus’s higher megapixel rating, Pentax’s sensor size provides a 1.5x crop factor and roughly 64% more sensor area - beneficial for noise control, dynamic range, and shallow depth of field.

From my pixel-peeping and lab tests, the Olympus offers:

• Higher resolution: 4032×3024 pixels allow more cropping latitude and fine detail capture.
• Better noise performance: The TruePic III+ processor and CMOS tech enable usable ISOs up to 3200, with cleaner shadows compared to household noisy shots out of the Pentax.
• Broader dynamic range: DxOMark-derived measures (10.3 EV) edge the Pentax’s CCD sensor, promoting richer landscapes and better highlight retention.

The Pentax, however, brings distinctive color depth and tonal rendition thanks to its CCD sensor, revered in certain circles for warm, natural hues especially in portraits and in-camera JPEG processing (albeit here our analysis excludes JPEG bias). Its strengths lie in delivering a pleasing “film-like” aesthetic right out of camera.

Both cameras unfortunately lack video capabilities, a limitation for hybrid shooters but typical for DSLRs of their generation.

Image quality summary: Olympus’s sensor and image pipeline excel in resolution and low light, suiting landscape and travel photographers needing punchy sharpness and versatility. Pentax’s sensor favors those wanting classic color signature and good low ISO portraits.

Compose with Confidence: Autofocus and Shooting Performance

The autofocus system is the camera’s eye in motion. It defines not only focusing speed but also usability across genres - crucial for wildlife, sports, macro, or everyday street photography.

The Olympus E-600 employs:

• A 7-point autofocus system with contrast and phase detection hybrid technologies.
• Face detection autofocus, a relatively advanced feature in this era.
• Continuous autofocus and live-view phase detection, easing spot-focus tasks in live view.

Pentax K100D S counters with:

• An 11-point autofocus array - larger than Olympus’s - though it relies solely on phase detection.
• Lacks live view and face detection, which handicaps precision focusing in tricky or video scenarios.
• Continuous AF support but no tracking or eye-detection.

In practice, I noted the Olympus E-600’s autofocus as quicker and more accurate in live view and static portraits due to its hybrid system, especially indoors or low light. The Pentax’s superior number of AF points theoretically gives it better coverage, but the older AF technology struggled in challenging contrast conditions and moving subjects.

Neither camera is geared for fast-action sports or wildlife; burst speeds max at 4fps (Olympus) and 3fps (Pentax) - modest compared to modern cameras. Olympus’s slightly faster continuous shooting provides a small advantage shooting informal action or kids.

Screens, Viewfinders, and Usability in the Field

Viewing your image and interacting with the camera interface matters deeply, especially for on-the-go photographers juggling lighting and composition.

Olympus shines with its bright, fully articulated 2.7-inch LCD. Despite modest 230k-dot resolution, the articulation transforms shooting styles - perfect for low-angle macros, self-portraits, or overhead shots. The HyperCrystal technology ensures good visibility in sunlight.

Pentax’s fixed 2.5-inch LCD at 210k dots is serviceable but limited for those seeking flexibility in framing tough angles. The top-mounted LCD fills a functional space, showing shutter speeds, aperture, and exposure compensation quickly.

Both cameras offer intuitive menus and basic customization, though the Olympus has fewer dedicated buttons (non-illuminated) and suffers the absence of touch support. The Pentax’s layout feels more traditional and tactile due to its larger body.

The Other Essentials: Build Quality, Sturdiness, and Weather Resistance

Neither the E-600 nor the K100D S claim extensive weather sealing. Both lack dustproof, splash-proof, or freeze-proof certifications. The Olympus is marginally better built, boasting a magnesium alloy top plate offering some sturdiness versus Pentax’s largely plastic construction.

In everyday use, both handled beginner to enthusiast-level tasks well, but neither is suited to heavy-duty professional environments or extreme outdoor conditions. I’d advise packing a rain cover if planning landscape or wildlife fieldwork in adverse weather.

Lens Ecosystem and Compatibility: What Glass Will You Mount?

Lens availability changes everything about system versatility.

• Olympus E-600: Uses the Micro Four Thirds mount, supporting approximately 45 native lenses available from Olympus and Panasonic. Despite the modest lens count circa 2009, the system has since seen explosive growth with many more quality primes and zooms available.
• Pentax K100D S: Employs the Pentax KAF2 mount, compatible with over 150 lenses spanning modern optics, legacy glass, and third-party models from Sigma, Tamron, etc.

Since the K100D S is APS-C, lenses will offer a more relaxed field of view compared to the Olympus’s Four Thirds 2.0x crop factor (effectively 2.1x multiplier in data). Sports and wildlife photographers may prefer the longer reach from the Olympus sensor size/crop factor combo, but outdoor shooters also benefit from Pentax's larger sensor.

Both cameras feature sensor-based image stabilization, a notable advantage for low light and handheld macro shooting.

Battery Life and Storage: Power and Capacity in Practice

Olympus employs a proprietary battery pack rated for about 500 shots - solid endurance for a compact DSLR, meaning fewer interruptions on travel or full-day shoots.

Pentax relies on four AA batteries with no official rating but generally falls short of lithium-ion pack endurance. While AA batteries may seem less convenient, they allow emergency replacements worldwide - handy for travelers in remote locations.

Storage-wise, Olympus sticks with Compact Flash (Type I/II) and xD cards - a less common combo today - while Pentax uses SD/SDHC cards, still the current standard for save. This difference affects memory card compatibility and expense.

Real-World Image Gallery: Evaluating Output Quality

Nothing beats visual samples when choosing a camera. I’ve compiled a gallery showcasing both cameras shooting an array of subjects under varied lighting - portraits, landscapes, macro, and street scenes:
