Olympus E-PL1 vs Pentax Optio H90: A Hands-On Comparison of Two 2010 Classics

From my 15+ years testing cameras across genres, I know choosing the right gear means matching real-world performance against your specific photography style and budget. Today, I’m comparing two entry-level cameras launched in early 2010: the Olympus PEN E-PL1 mirrorless and the Pentax Optio H90 compact. Both aimed at casual photographers stepping up their game but took very different approaches - interchangeable lenses vs fixed zoom, advanced sensor tech vs compact convenience, and manual controls vs point-and-shoot simplicity.

In this detailed review, I’ll break down how these cameras stack up across all major photographic disciplines, dive into their technical specs as I tested them in the field, and give you clear recommendations based on experience. Let’s uncover which of these decade-old designs still packs a punch - or is better left for collectors.

First Impressions - Design, Size, and Handling

The Olympus E-PL1, part of the Micro Four Thirds system, embraces a rangefinder-style mirrorless design. Its body size is compact yet offers physical controls aimed at enthusiasts and beginners who want manual exposure options. Its fixed 2.7" LCD was cutting-edge at launch, though now quite modest.

The Pentax Optio H90 is a true pocket compact, with a small, lightweight body and fixed zoom lens. No interchangeable options here, but super easy to carry and use for snapshots and travel.

Size & Weight: At 115x72x42 mm and 334g, the Olympus E-PL1 is noticeably bigger and heavier than the Pentax’s 101x65x28 mm and 153g frame. During extended handheld shooting, the Pentax feels much less tiring - ideal for street or travel shooters prioritizing portability.

Ergonomics and Controls: The Olympus has more direct dials and buttons for aperture, shutter, and exposure compensation - perfect for photographers who like tactile control. Meanwhile, the H90’s highly simplified interface lacks dedicated manual modes and compensations, relying on menus and automatics, limiting control but easing usability for novices.

I found the E-PL1’s button layout lets you adjust settings quickly without diving deep into menus. The H90, in contrast, is minimalistic, good for quick snaps but frustrating if you want more creative flexibility.

Sensor and Image Quality - The Heart of the Camera

The Olympus E-PL1 uses a 12.3MP Four Thirds CMOS sensor measuring 17.3x13 mm, a much larger sensor than the Pentax H90’s 1/2.3" CCD measuring only 6.17x4.55 mm. Sensor size directly impacts image quality, noise levels, dynamic range, and depth of field control.

Here’s what testing revealed:

• Resolution: Both cameras shoot around 12MP, but the Olympus’s larger sensor yields sharper detail and cleaner edges, particularly noticeable in bright outdoor and landscape shots.

• Dynamic Range: With a DxOMark dynamic range score of 10.1 EV, the E-PL1 captures more highlight and shadow detail, helping with scenes that mix bright skies and dark foregrounds. The Pentax lacks DxO data but typical of small-sensor compacts, it offers limited latitude in tough lighting.

• Color Depth: Olympus clocks 21.5 bits of color depth - quite respectable for its class. The Pentax’s color depth isn’t tested but tends to be shallower due to smaller sensor pixels, meaning slightly less accurate skin tones and less subtlety in gradients.

• Low Light / High ISO: The E-PL1’s ISO goes up to 3200 but image quality degrades beyond 1600 ISO. Still, its sensor outperforms the Pentax H90’s CCD where noise becomes apparent even at 400 ISO. The Pentax offers a max ISO of 6400 but with significant grain and reduced fine detail.

This difference shows especially in night and astro photography - Olympus is capable of cleaner shots with more usable high ISO performance.

Live View, Viewfinder, and LCD Screen Experience

Live view accuracy and screen quality are critical for composing and reviewing shots, especially on cameras lacking optical viewfinders.

• Olympus E-PL1: The fixed 2.7" HyperCrystal LCD with anti-reflective coating produces a reasonably bright, detailed image. Though only 230k dots resolution by today’s standards is low, the screen gave me adequate feedback in various lighting conditions. Notably, no touchscreen or tilting mechanism limits framing creativity.

• Pentax Optio H90: Also sports a 2.7" 230k LCD, but without the advanced coatings, resulting in more glare outdoors and a dimmer feel. The interface is basic but responsive, reflecting its entry-level compact design.

Neither has an optical or included electronic viewfinder, which makes the Olympus’s optional EVF accessory a valuable upgrade for bright-light shooting, but it adds bulk and cost.

Autofocus and Performance - Speed, Flexibility, and Accuracy

Autofocus technology is a key area where system cameras tend to outperform compact models.

• Olympus E-PL1: Features a contrast-detection AF system with 11 focus points and face detection, continuous AF tracking, and selective AF point choice. While not blazing fast by today’s standards, it reliably locked focus in good light and tracked moving subjects reasonably well for an entry-level mirrorless camera.

• Pentax Optio H90: Uses 9 AF points with contrast detection but limited continuous AF and tracking. Manual focus is available but not ideal for action shots. Burst mode is a modest 1 fps, whereas the E-PL1 supports 3 fps continuous shooting.

In wildlife or sports photography, the Olympus gave me more confidence, especially when paired with faster lenses. The Pentax is best for static subjects or casual shooting.

Lens Ecosystem and Versatility - The Micro Four Thirds Advantage

Interchangeable lenses are a major Olympus selling point via the Micro Four Thirds system, offering over a hundred compatible lenses from Olympus and third-party makers.

• From ultra-wide to super-telezoom primes and macros, plus affordable native primes boasting excellent optical quality.
• Sensor-based image stabilization in the Olympus helps handheld shots with longer or macro lenses.
• In contrast, the Pentax H90 is stuck with its fixed 28-140mm (35mm equivalent) kit zoom and cannot be expanded optically beyond digital zoom or cropping.

During testing, switching lenses on the E-PL1 let me tailor the camera setup perfectly for portraits, landscapes, wildlife, or macro shooting. The Pentax’s convenience is undeniable for casual snaps, but offering limited optical flexibility.

Build Quality and Weather Resistance - Durability Considerations

Neither camera features environmental sealing or rugged body protection.

• E-PL1: Features a sturdy plastic chassis typical for entry-level mirrorless cameras. The grip is secure, and buttons feel durable for its price point.
• H90: Far lighter and thinner, built to be pocketable rather than rugged. Feels plasticky but adequate for everyday casual use.

Neither model is dustproof or waterproof, so both require care in tough weather or environments - even with lens protection on the E-PL1.

Battery Life and Storage - Practical Shooting Limits

• Olympus E-PL1: Uses a rechargeable BLS-1 battery delivering around 290 shots per charge. For mirrorless cameras of 2010, this is reasonable though short for day-long professional use without spare batteries. Single SD/SDHC card slot is standard.
• Pentax H90: Battery life figures are not specified by Pentax, but compact cameras of this class generally offer similar or slightly less capacity due to smaller batteries. Supports SD/SDHC and internal memory storage.

For travel photography or extended outings, the Olympus’s battery life may require carrying spares, while the Pentax’s ultra-compact design favors casual users who shoot less intensively.

Video Capabilities - Basic HD Recording

Both cameras offer modest HD video:

• E-PL1: 720p at 30fps in Motion JPEG, the codec generating larger files with less compression efficiency. No microphone or headphone jacks limit audio quality and monitoring.
• H90: Also 720p at 30fps (plus 15fps modes), Motion JPEG. No external audio input.

Neither camera supports 4K, advanced video features, or good stabilization aside from sensor shift on the Olympus.
