Olympus E-PL8 vs Pentax E70: A Hands-On Comparison from My Lens to Yours

As someone who’s tested thousands of cameras over the years - from pro-level beasts to quirky compacts - I often find myself drawn to unexpected matchups. Today, I’m diving deep into two very different cameras: the 2016 Olympus PEN E-PL8, a mirrorless micro four thirds entry-level model, and the 2009 Pentax Optio E70, a small sensor compact. On paper, their specs are worlds apart. Yet both served as accessible photographic tools in their time, and I’ve found each has a story to tell for enthusiasts hunting for value, portability, or a second camera.

Let’s embark on a detailed journey through their design, image quality, usability, and how they perform across diverse photographic genres. My goal? To arm you with practical insights and honest evaluations based on real-world use, so you can confidently decide which camera could be your next companion or backup.

Handling and Ergonomics: Feel the Difference in Your Hands

The Olympus E-PL8, as a rangefinder-style mirrorless camera built on the Micro Four Thirds (M43) system, instantly feels more substantial and thoughtfully designed compared to the ultraportable Pentax E70 compact. We’re talking about a significant size and weight difference, as you can see in this physical comparison:

At 357 grams and measuring 115 x 67 x 38 mm, the E-PL8 offers a solid grip and is well suited to extended shooting sessions without fatigue. The camera’s retro-influenced styling and tactile controls elevate the experience - I particularly like how the tilting 3-inch touchscreen responds smoothly to my thumbs and fingers.

Contrast this with the Pentax E70, a compact weighing only 175 grams and sized at 94 x 61 x 26 mm. It’s pocket-friendly for sure, but the fixed lens and smaller screen make it less comfortable for intensive photographic work. Handling the Pentax feels more like using a consumer point-and-shoot camera, and this is evident in its sparse design and smaller controls.

Looking from above, the Olympus lays out its dials and buttons ergonomically, supporting rapid adjustments in diverse shooting scenarios:

This control architecture enables smooth transitions between modes like aperture priority, shutter priority, and manual exposure, which the Pentax lacks entirely. On the E70, simplicity reigns - there’s no manual exposure mode or customizable buttons, just point-and-shoot immediacy.

In practice: If you value greater control over your settings, especially for creative photography, the Olympus presents a more professional toolkit with better ergonomics. But if absolute portability and quick spontaneous snaps are your thing, the Pentax may appeal.

Sensor and Image Quality: Seeing is Believing

A camera’s sensor is its heart, and the difference here is pronounced. The Olympus E-PL8 employs a Four Thirds CMOS sensor measuring 17.3 x 13 mm, with a 16-megapixel resolution that delivers detailed 4608 x 3456 images. The Pentax E70, meanwhile, sports a tiny 1/2.3-inch CCD sensor, only 6.08 x 4.56 mm in size, with 10 megapixels maxing out at 3648 x 2736 pixels.

This stark contrast in sensor dimensions and technology manifests clearly when you inspect image quality, noise performance, dynamic range, and color depth:

In my controlled studio tests and outdoor shoots, the Olympus’s larger sensor delivers noticeably cleaner images with richer tonality and less noise, especially beyond ISO 800. The Olympus’s sensor coupled with the TruePic VII processor excels in preserving detail in shadows and highlights, making it a versatile performer from bright sunlit landscapes to dim interiors.

The Pentax’s sensor, while adequate for casual snapshots, shows limitations quickly. Images exhibit visible noise starting from ISO 400, and shadow detail gets sacrificed without much dynamic headroom. Moreover, the smaller sensor’s 5.9x crop factor reduces your depth of field control and low-light capability.

Additionally, the Olympus supports RAW shooting, giving enthusiasts and pros full post-processing flexibility. The Pentax shoots only JPEG, limiting creative latitude out-of-camera.

Bottom line: For image quality, dynamic range, and creative potential, the Olympus’s sensor is in a different league, reinforcing its appeal to serious hobbyists.

Composing and Reviewing Images: Touchscreen and Interface Realities

In-the-field usability heavily depends on how you compose and review your shots. The E-PL8 offers a responsive, tilting 3.0-inch touchscreen LCD with 1,037k-dot resolution, making framing shots from low or high angles effortless and enjoyable.

I found the touchscreen interface intuitive, enabling quick touch focus, setting exposure points, and browsing images with tactile ease. The E-PL8 forgoes a built-in viewfinder, but you can optionally add an electronic finder - a worthwhile investment if you desire eye-level shooting in bright conditions.

The Pentax E70’s 2.4-inch fixed screen feels cramped and low-resolution (just 112k dots), and there’s no touchscreen functionality. Composing with it is less precise, especially in bright daylight, where reflections and glare become distractions. The lack of any viewfinder means always relying on the LCD - a challenge for more deliberate street, travel, or wildlife shots.

Practical insight: The Olympus’s better LCD and touchscreen enhance creative exploration and ease in challenging compositions, while the Pentax's basic screen positions it as a casual, grab-and-go device.

Performance: Autofocus, Burst, Stabilization, and Shooting Modes

Having tested both cameras extensively, I can confidently say they cater to different user demands in terms of speed and responsiveness.

The Olympus E-PL8 features 81 contrast-detection autofocus points with face detection and tracking capabilities. It offers single, continuous, selective, and multi-area AF modes, plus a respectable continuous shooting speed of 8 frames per second (fps).

I put the E-PL8 through various scenarios - portraits with moving subjects, rapid street scenes, and even some modest wildlife attempts. The autofocus is surprisingly quick and accurate for an entry-level model, locking onto faces and moving subjects without excessive hunting.

The camera’s built-in sensor-based 5-axis image stabilization dramatically enhances handheld sharpness, particularly valuable for macro, video, and low-light handheld shooting. This stabilization makes a tangible difference, easily rescuing shots where I otherwise would’ve needed a tripod.

By contrast, the Pentax E70 lacks any image stabilization and uses simple contrast-detection AF with only nine focus points. It supports single AF only, with no tracking, and no burst shooting. This makes it less suited to capturing fast action or complex compositions demanding pinpoint focus.

Its shutter speed range is limited (up to 1/2000 sec), which constrains creative flexibility under bright light situations with wide apertures.

To sum up: Olympus E-PL8’s AF system and stabilization support dynamic shooting styles and even some wildlife or sports snapshots, while the Pentax is strictly casual snapshot territory.

Varying Focus: Lens Ecosystem and Focal Range

One key advantage of the Olympus E-PL8 lies in its adoption of the Micro Four Thirds mount, compatible with an extensive lens ecosystem of over 100 optics from Olympus, Panasonic, and third-party makers.

This open lens selection - from compact primes to professional telephotos and fast zooms - means the E-PL8 can grow with your photographic ambitions, whether leaning toward studio portraits, wide-angle landscape vistas, or macro close-ups.

The Pentax E70’s fixed lens covers a narrow 35-105mm equivalent focal length with a modest aperture range of f/3.1-5.9. While decent for framing basic street or travel images, this bundled zoom restricts creativity, especially in low light or for shallow depth of field portraits.

Lens versatility takeaway: The Olympus wins hands down for system flexibility and future-proofing your photographic toolkit.

Shooting Across Genres: Which Camera Fits Your Style?

I tested both cameras across a spectrum of photography disciplines to better understand their strengths and weaknesses.

Portrait Photography

The Olympus’s larger sensor captures pleasing skin tones with smooth gradations and subtle bokeh effects when paired with fast primes. I enjoyed using its face detection and eye AF to lock focus on critical points. The Pentax managed acceptable portraits in good light but couldn’t replicate the creamy backgrounds or tone fidelity.

Landscape Photography

Thanks to its superior dynamic range and 16MP resolution, the E-PL8 rendered landscapes with crisp detail and balanced highlights. Weather sealing is absent but consistent build quality lets you shoot carefully outdoors. The Pentax’s lower resolution and sensor limitations led to flatter images lacking punch.

Wildlife and Sports

The Olympus’s AF tracking and 8fps burst rate allowed me to capture small birds in flight and local soccer matches with fair success. Pentax couldn’t keep up, no burst and sluggish AF meant many missed frames.

Street Photography

The Pentax excels with its extreme compactness and unobtrusiveness for candid snaps among crowds. The Olympus is slightly larger but still lightweight with quiet shutter modes - plus the tilting touchscreen enables creative compositions.

Macro Work

Olympus’s stabilization combined with versatile lenses enables sharp handheld macro images. Pentax’s fixed lens macro mode from 10cm can produce decent close-ups but lacks sharpness and magnification control.

Night / Astro Photography

E-PL8’s higher ISO ceiling and better noise control allow it to capture stars and city nights with more clarity. Pentax’s noise and sensor noise limit low-light usability.

Video Capabilities

Olympus records 1080p at 30fps with H.264 encoding and in-body stabilization benefiting handheld shots. Pentax maxes out at 720p and produces noisier video with no stabilization.

Travel Photography

Both are portable, but Olympus offers better battery life (~350 shots vs. unknown on Pentax), superior image quality, and lens interchangeability - the significant difference for travel storytelling.

Professional Work

While the Olympus lacks full weather sealing or professional file formats used in high-end systems, its RAW support and control modes make it a credible backup or secondary shooter for professionals on a budget.
