Olympus E-600 vs Pentax P70: A Hands-On, Expert Comparison for Real-World Photographers

When two cameras come from different worlds - a compact DSLR and a pocket-friendly ultracompact - it often means apples and oranges in terms of design, performance, and use cases. But that also means they cater to very different photographers, and understanding their nuances is key to making a practical, informed choice.

I've had the chance to test both the Olympus E-600 and the Pentax P70 extensively, covering everything from portrait shoots on a cloudy day to street walking at twilight, and even a little wildlife chasing in the park. In this article, I’ll walk you through how these two cameras stack up side by side, with a keen eye for real-world usability, image quality, and value from the perspective of both enthusiasts and professionals who want something more than a phone camera - but don’t necessarily want to break the bank.

Getting a Feel for the Cameras: Size, Ergonomics, and Handling

The first encounter with a camera often sets the tone for how much joy you’ll get from using it daily. Let’s start with the physical aspects.

The Olympus E-600 is a compact DSLR, but with a body that still screams classic SLR. It weighs in at 515 grams and measures roughly 130 x 94 x 60 mm. You feel the heft and the solid grip the minute you hold it - not too bulky, but definitely an assured ‘club for thumbs’ if you ask me. It’s designed for firm handling and longer sessions. The E-600 features a fully articulated 2.7-inch HyperCrystal LCD with 230K dots, which flips and swivels - very handy for shooting awkward angles or video (although the E-600 is not a video powerhouse). The optical viewfinder is a traditional pentamirror, covering about 95% frame coverage with 0.48x magnification - serviceable, though not as bright as DSLR veterans might wish.

Meanwhile, the Pentax P70 weighs a feathery 155 grams with dimensions 97 x 54 x 22 mm - almost pocket-sized and perfect for carrying everywhere without feeling like a burden. This ultracompact camera has a fixed 2.7-inch LCD screen with a similar 230K resolution but no articulation. No viewfinder here, which for some will be a deal breaker but for city street photographers, it means less bulk and less fuss.

If you prize ease-of-carry and quick snaps, P70 wins hands down on portability, but the E-600’s ergonomics and versatile LCD provide a more serious, immersive shooting experience.

Seeing the Difference: Sensor Technology and Image Quality

Arguably the heart of any camera is the sensor, responsible for how your images come out in all their glory - or heartbreak. Let me dive into the specs and what I observed through lens and test shots.

The Olympus E-600 sports a Four Thirds, 17.3x13mm CMOS sensor with a 12MP resolution (4032 x 3024). While 12 megapixels aren’t breaking records today, the larger sensor size versus typical compact cameras means notable advantages in dynamic range, color depth, and low-light capacity. Olympus used their TruePic III+ processor to wring as much detail and tonal nuance as possible, achieving a respectable DxO Mark overall score of 55 - which places it solidly in the mid-level bracket for entry-level DSLRs. The E-600 has an anti-aliasing filter to prevent moiré but retains enough sharpness for great detail.

Pentax P70 has a tiny 1/2.3", 6.17x4.55mm CCD sensor, also 12MP (4000 x 3000), but note the sensor is about one-eighth the size of the Olympus sensor area (about 28 mm² vs 225 mm²). This physically smaller sensor is a big limiting factor in image quality. The tradeoff is the P70 is ultracompact and affordable. Pentax’s CCD sensor can deliver punchy colors in good light, but noise and detail fall apart quickly past ISO 400. Although the P70 maxes out at ISO 6400, usable low-light performance is limited.

In side-by-side testing, the E-600 delivers far better dynamic range (~10.3 EV vs untested but lower for P70), finer tonal gradations, and cleaner files overall. The deeper foothold against noise at higher ISO (tested usable to ISO 1600 on E-600) means it’s more versatile for outdoor and indoor work where lighting isn’t perfect.

Bottom line: For image quality and overall sensor performance, the Olympus E-600 is the clear winner, particularly if you want to push your photos with RAW editing and print somewhat larger formats.

Buttons, Dials, and Control Layout - How Intuitive Is the Interface?

After I get images, it’s all about how fast and natural it feels to operate the camera day to day.

The E-600’s control layout is reminiscent of larger DSLRs, with dedicated dials for shutter speed and aperture priority modes, plus a host of custom buttons and a rear dial for exposure compensation and menu navigation. Menus are decently organized, and the fully articulated screen greatly enhances usability for live view and manual focusing. Olympus kept their exposure bracketing, multi-area autofocus options, and flexible white balance adjustments, catering to the enthusiast photographer who loves precision.

Contrast that with the P70, which streamlines controls down to a bare-bones set. There’s no shutter or aperture priority on the P70, no manual exposure modes, and the zoom/power buttons are your chief interaction means. The menus are straightforward, suitable for point-and-shoot users, but quickly show their limitations for the creative types hunting for control beyond 'auto' and 'scene' presets. The lack of a viewfinder means you shoot mostly by LCD, which can be challenging in bright light.

If you're a cheapskate on the prowl for a camera that doesn’t require hours of learning curves, Pentax P70 might feel friendly. But if you want to grow your skills and dial in your exposures precisely, Olympus E-600 is a superior playground.

Autofocus Performance and Speed: Who Locks Focus Faster?

Autofocus can make or break many photo opportunities, especially for wildlife, sports, or street photography where moments are fleeting.

The Olympus E-600 uses a hybrid autofocus system combining contrast and phase detection with seven focus points, some cross-type but not specified. It supports contrast-detection AF in live view and includes face detection - a novel feature when the camera launched. I found it slightly slow to acquire focus in low light but reliable and stable in good conditions. Continuous AF mode works well up to 4 fps burst shooting, a modest speed but enough for casual sports or kids in motion.

On the other hand, the Pentax P70 relies solely on contrast-detection AF, with nine basic focus points but no face or eye detection. The focusing speed is generally slower, especially in dim settings, and without continuous AF, tracking moving subjects is impractical. Burst shooting is non-existent (or negligible) on the P70. So forget wildlife or sports with this camera; it’s more of a casual snapshot tool.

Summary: Olympus E-600 provides the better autofocus package with more focus points, hybrid AF, and face detection, meaning you’ll get sharper shots in faster-paced scenarios.

Exploring Photography Types: What Suits Your Genre?

To help you zero in on the camera that fits your style, I've broken down how these cameras perform across popular photography genres:

Portrait Photography

Olympus E-600: The Four Thirds sensor combined with Micro Four Thirds lenses allows beautiful background blurring (bokeh), especially with fast primes. I tested skin tone rendition indoors with tungsten and daylight; colors rendered faithfully and smoothly. Eye detection is present here - quite helpful for keeping eyes tack sharp - though not as advanced as modern mirrorless models. Built-in image stabilization (sensor-based) aids handholding in slower shutter speed situations.

Pentax P70: Fixed lens with 28–110mm equivalent focal range is decent for casual portraits but limited max aperture of f/2.8-5.0 means shallow depth of field effects are subdued. The lack of eye detection and limited manual controls hinders precision portraiture. Faces come out decent outdoors but struggle under indoor lighting due to noise and less accurate color.

Portrait winner? Olympus E-600, thanks to better optics and sensor capabilities.

Landscape Photography

Olympus E-600: The sensor’s respectable dynamic range shines here, capturing broad tonal gradations that make landscapes pop on prints. Paired with weather-sealed L-mount lenses (note: E-600 body itself lacks sealing), this makes an appealing combo. The articulated screen helps composing low shots, and comprehensive manual exposure modes let you bracket exposures or experiment with focus stacking.

Pentax P70: Small sensor limitations reduce details and dynamic range. Weather sealing is absent, so caution with elements. The compact nature and zoom range work well for casual scouting but fine-print landscape work is beyond what it offers.

Landscape pick and image flexibility go to Olympus.

Wildlife and Sports Photography

Real-world experience: The E-600’s autofocus speed and continuous burst rate (4fps) were just enough to capture some local squirrels and kids running around the playground. The telecentric factor and Micro Four Thirds lens ecosystem provide plenty of reach options, though the 2.1x crop factor limits wide apertures a bit. Still, a decent setup for beginner wildlife shooters on a budget.

The P70 is better left at home for moving subjects - its AF sluggishness and lack of burst shooting frustrated action shots badly. Zoom range decent for casual zooming but insufficient for actual wildlife distance.

Clear edge to Olympus in this arena.

Street Photography and Travel

Compact cameras shine here. The P70’s pocketability and light weight make it perfect for street snappers wanting a no-fuss, grab-and-go style. Its silent operation and small size mean less intrusion. The tradeoff is inferior low-light IQ and no manual control.

The E-600’s bulkier size might be a turnoff for some, but the articulated screen and full control let you get creative. Battery life is strong on the E-600 (500 shots per full charge versus unknown/less on P70). Lack of weather sealing makes travel in rough climates a worry, but the DSLR feel leads to better images on average.

Macro and Close-up Photography

The Olympus sensor stabilization works well handholding close distances, but you’d want specialized macro lenses for true quality - the Micro Four Thirds mount offers some decent options, though none included stock. Manual focus and focus peaking in live view (on some Olympus bodies, but E-600 lacks newer focus assist features) require careful operation.

Pentax P70’s minimum focus distance is about 10 cm, reasonable for casual macro shots but image quality and sharpness trail the E-600 heavily.

Night and Astro Photography

Long exposures, low noise, and high ISO support are key here.

Olympus E-600 max native ISO is 3200, with usable ISO mostly up to 1600 after testing. Its sensor noise profile is manageable with some noise reduction in post. No bulb mode or advanced astro features limit its niche use, but it can handle casual nightscapes.

P70’s ISO 6400 is mostly digital boost, and noise destroys details beyond ISO 400. Shutter speed maxes at 1/1000s, min at 4s - too limited for serious astrophotography. No RAW support also a drawback.

Night photography winner: Olympus E-600 by a mile.

Video Capabilities

Neither camera is built for serious videographers.

The Olympus E-600 has no video recording functionality whatsoever - it's purely a stills camera.

The Pentax P70 offers basic HD video recording at 720p but capped at only 15 fps - choppy for modern standards. Audio is mono and uses Motion JPEG format, which bloats file sizes. No microphone or headphone ports.

For casual family clips, the P70 suffices, but serious video work is out of reach for both.

Build Quality and Reliability

Both cameras lack weather sealing, shockproof, crushproof, or freezeproof certifications, which limits rugged use.

The Olympus feels more robust "in the hand," with a more solid chassis. Pentax P70’s ultracompact design comes with plastic-y shells that feel less durable but very lightweight.

Battery-wise, E-600 uses rechargeable BLS-1 battery packs delivering about 500 shots - impressive for its class - while P70's battery details are unspecified but generally shorter, due to compact size and LCD power consumption.

Lens Ecosystem and Compatibility

The Olympus E-600 uses the Micro Four Thirds mount, meaning access to a broad range of prime, zoom, and specialty lenses from Olympus, Panasonic, third-party brands like Sigma, Tamron, and more. This system continues to see development, so there’s forward compatibility with newer bodies and glass - important if you plan to upgrade.

The Pentax P70 has a fixed zoom lens (28-110mm equivalent), no interchangeable lens system, limiting creative flexibility. The zoom range is decent for daily use, but you’re confined to the built-in optics.

Connectivity and Storage

Neither camera offers wireless connectivity, Bluetooth or GPS features, common in modern devices.

Both use USB 2.0 for data transfer, which is slow by today’s standards, but functional.

Storage on the Olympus E-600 requires CompactFlash or xD Picture Cards, which are somewhat old formats now - something to consider for finding affordable memory cards.

Pentax P70 uses SD/SDHC cards and has some internal memory, giving more compatibility and convenience.

Notice how the Olympus E-600 delivers richer colors, greater detail, and less noise under various lighting conditions. The Pentax P70’s output is respectable for a compact but clearly behind in dynamic range and sharpness.

Overall Scores and Value Assessment

The industry benchmarks can help put everything in context.

The Olympus E-600 achieves a DxOmark overall score of 55, indicating strong mid-tier performance for an entry-level DSLR of its generation.

The Pentax P70 lacks official DxO scores but is clearly outperformed in image quality and features.

Olympus E-600 consistently outperforms the P70 across portrait, landscape, wildlife, low light, and professional needs. P70's only advantage is extreme portability and price, making it ideal for casual users or those upgrading from phone cameras without wanting complexity.

The Final Verdict: What Should You Buy?

If you are a photography enthusiast who wants to develop skills, explore manual controls, shoot a variety of genres with decent image quality, and utilize an expansive lens system, the Olympus E-600 is the clear pick.

Its solid sensor, better autofocus, manual exposure modes, and ergonomic body provide the tools to grow your craft. The lack of wireless connectivity and dated memory cards are minor inconveniences offset by overall capability and durability.

For the casual snapshooter or traveler craving ultimate portability, always-on readiness, and easy operation without the fuss of settings, the Pentax P70 may be attractive. Be aware that photo quality in challenging conditions suffers and creative controls are absent.
