Olympus PEN E-PL8 vs Pentax Optio H90: The Tale of Two Cameras from Different Worlds

Choosing a camera isn’t just about specs on paper. It’s about how a camera performs in your hands, suits your style, and fits your specific photography needs. Today, I’m diving deep into a comparison between two very different cameras that might at first glance seem like apples and oranges - the Olympus PEN E-PL8, a stylish entry-level mirrorless from 2016, and the Pentax Optio H90, a compact point-and-shoot from 2010. Both carry their own legacy, and I’ve spent ample time working with each to bring you an honest, experience-driven breakdown. We’ll cut through concepts, sensor tech, autofocus tricks, ergonomics, real-world use, and more to help you figure out which camera deserves a spot in your kit, or if you’re better served elsewhere altogether.

Let’s start by taking in the physical size, design, and ergonomics.

Size, Handling, and Design – First Impressions Matter

When you pick up a camera for the first time, it speaks volumes about how you’ll interact with it day-to-day. The Olympus E-PL8 embodies that classic rangefinder-style mirrorless feel: compact with a clever blend of retro charm and modern practicality. The camera measures 115 x 67 x 38mm and weighs a comfortable 357g - light enough for travel, yet solid enough to feel reassuring in the hand.

Contrast this with the Pentax H90, a pocket-friendly compact at 101 x 65 x 28mm, tipping the scales at a mere 153g. It’s slim and discreet, designed to disappear in your pocket or bag, ready for quick snaps. But there’s a tradeoff - smaller size means smaller controls, which can feel fiddly during serious shooting.

Looking at the size comparison here, you can see the E-PL8’s thicker grip contextually gives you better handling stability, especially with larger lenses. The Pentax H90’s slim profile is undeniably convenient, but don’t expect the same tactile feedback or substantial feel.

The Olympus’s body sports a tilting touchscreen, a modern touch that practically screams “user-friendly,” while the Pentax sticks with a fixed non-touch LCD - serviceable when composing shots, but not ideal for intuitive menu navigation or live view adjustments.

In terms of design language, the E-PL8 channels that “photographer’s camera” vibe with subtle textured accents and a clean top deck. The H90 opts for simplicity, with all functions streamlined into small buttons and a tiny dial. If you have larger hands or love manual control, the Olympus gives you more breathing room.

The Heart of the Machine: Sensor, Image Quality, and Processing Power

Let’s get to the crux - image quality. The Olympus PEN E-PL8 leverages a Four Thirds sized CMOS sensor measuring 17.3 x 13mm, packing 16MP resolution. The Pentax Optio H90, by comparison, wields a far tinier 1/2.3” CCD sensor (about 6.17 x 4.55mm) with 12 megapixels.

Why does sensor size matter so much? Bigger sensors capture more light, have better dynamic range, exhibit lower noise, and generally produce cleaner, richer images. The E-PL8’s Four Thirds sensor is roughly eight times larger in surface area than the H90’s CCD chip, giving it a massive edge in image quality and versatility.

In practical testing with both cameras under various lighting conditions, the Olympus shines in low light, better tonal gradation, and produces crisper detail. The Pentax struggles, especially at high iso settings, where noise becomes a limiting nuisance (remember ISO 6400 on a tiny sensor isn’t the same as on a larger one).

Color rendition is a subjective realm, but the E-PL8’s TruePic VII processor ensures pleasing skin tones and accurate hues, ideal for portraits and everyday shooting. The H90 has somewhat flatter color profiles, with an emphasis on punchiness that sometimes sacrifices subtlety.

I’ve shot landscapes side-by-side and the Olympus retains fine detail without the mushiness you sometimes see from the Pentax’s sensor and lens combo.

Control Layout and User Interface - How Intuitive Is the Experience?

The Olympus thoughtfully arranges controls with a compact yet accessible button layout, giving you dedicated dials for exposure compensation, mode selection, and easy access to key features. The touch-enabled 3-inch LCD - with 1,037k dots resolution - also allows quick focus point selection and menu control, perfect for those who prefer tapping and swiping.

The top deck comparison shows the Olympus hosting a neatly organized mode dial with PASM options, custom modes, and direct access buttons, giving enthusiasts and beginners alike room to explore and grow.

The Pentax H90 features a much simpler interface with fewer manual controls, reflecting its compact point-and-shoot nature. A small mode dial includes basic scene modes and fully automatic presets, while a physical zoom lever replaces a dedicated aperture or shutter dial.

In practice, the Olympus E-PL8 feels more like a creative companion, encouraging experimentation with manual controls and fine exposure tweaks. The H90 is better suited for casual photographers who want simplicity above all else.

Autofocus Systems - Accuracy, Speed, and Reliability in the Moment

Autofocus can make or break a shoot, especially when your subject is moving or in challenging lighting. The Olympus PEN E-PL8 features an 81-point contrast-detection AF with face detection, continuous AF options, tracking, and touch-to-focus on its screen. While not as blisteringly fast as its flagship siblings with phase detection, it’s more than capable for casual portraits, street photography, and slow-moving subjects.

On the other hand, the Pentax H90 offers a basic 9-point contrast-detection system with face detection disabled. It’s serviceable for static compositions but hamstrung for action, and you’ll notice lag or hunting in dim light or busy scenes. There’s barely a whisper of continuous autofocus, and no manual aperture or shutter priority modes to lean on.

For wildlife or sports shooters, the Olympus’s ability to track subjects and maintain focus during bursts (up to 8fps) makes all the difference. The H90, capped at a sluggish one frame per second continuous shooting speed, cannot keep up with fast-moving subjects.

Versatility in Lenses: Ecosystem and Compatibility

One of the strongest points of the Olympus E-PL8 is its Micro Four Thirds lens mount - a mature, robust ecosystem offering over 100 lenses from Olympus, Panasonic, and many third-party manufacturers. From ultra-wide landscapes to macro and telephoto zooms, this system satisfies enthusiasts dabbling across genres and professionals needing specialty glass.

The Pentax H90, with a fixed 28-140mm (5x optical zoom, f/3.5-5.9 variable aperture) lens, is limited to what’s built in. It’s commendably versatile for casual shooting but not expandable. You can do moderate zoom work but miss out on the optical quality and creative effects of prime lenses or specialized optics.

If you value growing your gear collection, or want more precise control over depth of field and focal qualities, the Olympus clearly wins.

Screen and Viewfinder Experience: Composing and Reviewing Your Shots

The Olympus E-PL8 offers a 3-inch tilting touchscreen LCD with 1,037k dots - a sizable, sharp display that helps when you’re shooting from high or low angles. It’s responsive, intuitive, and enhances framing flexibility.

In contrast, the Pentax H90’s 2.7-inch fixed LCD is smaller and sports a low resolution of 230k dots, making it difficult to clearly preview fine detail or judge focus perfection, especially in bright daylight.

Neither camera includes a built-in electronic viewfinder, though Olympus users can purchase an optional EVF attachment if they insist.

For video enthusiasts or vloggers, the E-PL8’s articulating touchscreen is a tangible hack to creative framing, while the Pentax’s basic fixed screen feels outdated.

Real-World Performance: Photographic Genres Explored

Let’s put these cameras through their paces across various photography styles you might pursue.

Portrait Photography

Olympus’s Four Thirds sensor combined with the 5-axis image stabilization and 81-point autofocus gives it a clear advantage. Skin tones render warmly and naturally, and the camera handles bokeh well on fast lenses from the MFT lineup.

Pentax’s small sensor and fixed lens struggle to isolate subjects or achieve creamy background blur. Autofocus accuracy is sufficient for family snapshots but lacks eye detection or face priority.

Outcome: Olympus provides more pleasing portraits with artistic control.

Landscape Photography

The E-PL8’s higher resolution (16MP) and better dynamic range handle skies and foliage more faithfully, retaining detail in shadows and highlights. The vast lens lineup includes ultra-wides essential for expansive vistas.

Pentax’s smaller sensor and limited zoom focus range can struggle with sharpness across the frame, and you’re stuck with a 5x zoom lens - fine for casual landscapes but limiting for serious exploration.

Weather sealing? Neither offers it, so keep rain covers handy.

Wildlife and Sports

Burst shooting at 8fps and tracking autofocus move the Olympus head and shoulders above the Pentax’s single frame speed and basic AF. With telephoto MFT zooms, the E-PL8 handles birds, pets, and events competently.

The Pentax H90 hobbles - slow AF, limited zoom reach, and a basic sensor mean it’s best left for casual snapshots, not action.

Street and Travel Photography

The Pentax’s compact, pocketable size makes it less conspicuous, ideal for snapshots on the go or street scenes where drawing attention is unwelcome. The Olympus, while compact, is more noticeable but still travel-friendly.

Battery life favors the Olympus at about 350 shots per charge, while the Pentax datasheet is silent, but expect fewer shots given the older design.

If discretion and instant accessibility top your list, the Pentax wins on portability; for image quality and versatility, the Olympus takes it.

Macro and Close-up

Neither camera features a dedicated macro mode, but the Pentax lens allows focus as close as 10cm. The Olympus benefits from interchangeable macro lenses in the MFT system, and its sensor-based stabilization aids handheld macro work.

For serious macro shooters, the Olympus system is more flexible.

Night and Astro Photography

Thanks to a larger sensor and higher native ISO range (200-25600), the Olympus E-PL8 is more capable shooting under starlight or in dim scenes. Night noise is better controlled, and bulb exposures are supported.

The Pentax H90’s small sensor and low max ISO limit its ability here.

Video Capabilities

Video is often left out in compact cameras, but a quick rundown:

• Olympus PEN E-PL8 shoots full HD 1080p at 30 fps with 5-axis IS aiding handheld stability. The absence of microphone or headphone jacks is a downside for videographers, but the touchscreen makes focus during filming easier.

• Pentax H90 maxes out at 720p HD, 30 fps with no stabilization during movie mode. It’s more a novelty for video than a serious tool.

Olympus wins hands down for casual video content creators.

Professional Work and Workflow

The Olympus supports RAW capture, allowing full post-processing and greater creative control. With its Micro Four Thirds mount, workflow integration in Adobe Lightroom or Capture One is seamless.

The Pentax does not support RAW, limiting post-processing flexibility. This alone disqualifies it for professional use.

Build Quality, Weather Resistance, and Durability

Neither camera offers official weather sealing or ruggedization. Both require care in adverse conditions.

The Olympus body feels more robust with higher-quality plastics and metal components; the Pentax chassis is basic but well put together for a compact.

Battery Life and Storage

Battery life on the Olympus averages around 350 shots per charge using a proprietary rechargeable pack - decent for a mirrorless but consider spares on long trips. Storage is straightforward with single SD card slot compatibility.

The Pentax uses the older D-LI68 battery, no official shot count given, but generally lower endurance given its age and compact camera design. Storage includes SD card and some internal memory.

Connectivity: Is Wireless Modernity Present?

The Olympus E-PL8 includes built-in Wi-Fi for image transfer and remote control, a feature I personally find indispensable for social sharing or quick workflows on the go. Unfortunately, it lacks Bluetooth or NFC.

The Pentax H90 predates common Wi-Fi standards but supports Eye-Fi cards for wireless transfers - a clunkier workaround in today’s world.

Price-to-Performance: What Does Your Budget Buy?

Originally priced near $500, the Olympus PEN E-PL8 reflects solid value for an entry-level mirrorless system. Its sensor, build, and lens ecosystem provide a clear upgrade path.

The Pentax Optio H90, available at under $150 on the used market, offers a basic, affordable compact experience aimed at casual shooters or those wanting a simple pocket camera.
