Olympus E-PL1s vs Sony QX100: A Comprehensive Comparison for the Discerning Photographer

When we pull two cameras from vastly different design philosophies and eras onto the comparison mat, the ensuing contest is as revealing as it is entertaining. The Olympus E-PL1s and Sony QX100 were both aimed at improving everyday photography, but they approached this mission in strikingly unique ways. Having tested these cameras extensively under diverse conditions, I’m here to unpack the nuts and bolts, the real-world capabilities, and exactly who should consider each. By the end of this piece, you’ll possess an informed, nuanced perspective rooted in hard evidence and lived experience.

Form Factor and Handling: Classic Mirrorless Meets Lens-Style Innovation

Olympus’s E-PL1s is a traditionally built rangefinder-style mirrorless with a solid Micro Four Thirds heritage. At 115x72x42mm and 334 grams, it strikes a nice balance between portability and handling comfort. The grip design, subtle button layout, and relatively light weight make it easy to cradle for extended shooting sessions. I found its solid build reassuring without being heavy-handed; you can shoot handheld landscapes or portraits all day without undue fatigue. The sensor-stabilized image stabilization is a practical plus that further enhances its real-world usability.

The Sony QX100, in striking contrast, is a lens-style camera designed mainly to be paired with a smartphone - no traditional viewfinder or body controls beyond the shutter and zoom rings. At just 63x63x56mm and 179 grams, it's almost pocketable but trades ergonomic convenience for compact eccentricity. Handling it solo feels alien compared to typical cameras: no eye-level viewfinder, no dedicated screen - instead, it relies entirely on a tethered smartphone app for composition and settings. This can work well if you’re accustomed to smartphone photography workflows and value extreme portability; otherwise, it can feel restrictive.

Looking at control layouts, the Olympus offers standard dials and buttons for shutter priority, aperture priority, exposure compensation, and manual focus - a full buffet for enthusiasts wanting immediate tactile control. The QX100 has minimalist hardware controls: zoom ring and shutter button, with all other settings controlled digitally through the app. That’s a crucial difference hinging on the user’s shooting style and preference.

Sensor and Image Quality: Micro Four Thirds vs 1-inch BSI-CMOS

A key technical battleground lies in sensor design and imaging outcomes.

The Olympus E-PL1s features a 17.3x13mm Four Thirds CMOS sensor with 12 effective megapixels. This is somewhat standard fare for entry-level mirrorless cameras of its time, balanced for resolution and noise control. Its native ISO sensitivity spans 100-6400, with sensor-based stabilization providing an advantage for handheld shooting. The anti-alias filter smooths out moiré, favoring natural, slightly softer images rather than razor-sharp oversampling. It’s a pragmatic choice that complements Olympus’s color science - pleasant skin tones and vibrant yet controlled color reproduction emerge from the TruePic V processor’s image rendering.

The Sony QX100 ups the ante with a 1-inch (13.2x8.8mm) back-illuminated CMOS sensor boasting 20 megapixels, roughly 5472x3648 resolution. The BSI technology is designed for greater low-light sensitivity and dynamic range, and the fixed lens is an impressive focal range of 28–100mm equivalent at an impressively bright aperture ranging from f/1.8 to f/4.9. Wide aperture at the wide end helps bokeh and low-light capacity, while the longer reach adds compositional versatility.

During hands-on tests, the QX100’s sensor delivered crisper images with more detail at base ISO, owing to its higher resolution and newer technology. Pushing the ISO revealed slightly better noise control on the Sony, but not dramatically so given the Olympus’s effective stabilizer allows lower ISOs with slower shutter speeds. However, Olympus’s Micro Four Thirds sensor crops the field significantly compared to a full-frame standard, and the QX100’s 1-inch sensor sits between Micro Four Thirds and smaller compact sensors, giving it the potential to outperform many entry-level mirrorless sensors in raw detail capture.

LCD and User Interface: A Tale of Two Screens

The Olympus E-PL1s offers a 2.7-inch fixed HyperCrystal LCD with 230k dots and anti-reflective coating. While not particularly high resolution by today’s standards, it was respectable for its launch period and sufficient for framing and basic playback. It lacks touchscreen functionality, which in this era was still a novelty rather than a staple. The interface is intuitive, logical, and responsive, with physical buttons supplementing menu navigation.

In contrast, the Sony QX100 has no dedicated LCD screen; instead, it offloads display and control functions entirely to your smartphone/tablet through the PlayMemories Mobile app. This touchscreen interface offers live view, exposure controls, and focus selection but is inherently dependent on wireless connectivity reliability and smartphone processing speed. Connectivity hiccups can disrupt the shooting flow, though the touchscreen controls are generally smooth once connected.

For photographers accustomed to quick, tactile navigation without smartphone intervention, the Olympus interface offers a more straightforward experience. For those committed to an app-based flow and comfortable integrating their device into shooting, Sony’s solution offers a kind of technological novelty - potentially freeing, though limiting in practice.

Autofocus and Shooting Performance: Precision vs Portability

Olympus’s E-PL1s employs a contrast-detection-based autofocus system with 11 selectable focus points and face detection capabilities. In practice, this system delivers accurate focusing in well-lit conditions but can struggle with fast-moving subjects or very low light - typical for contrast-detection AF in this class. Continuous autofocus at 3 fps burst rate is serviceable for casual action but limited for demanding sports or wildlife scenarios.

The Sony QX100 relies on contrast detection as well, with touch focus selectable via the smartphone app. Unfortunately, autofocus speed is noticeably slower and less reliable on moving subjects. There is no continuous autofocus tracking per se, and burst shooting is minimal to non-existent due to the reliance on smartphone processing and connectivity. Manual focus is accessible but, again, awkward without traditional controls.

In testing wildlife and sports scenarios, the Olympus felt more capable despite modest specs, with quicker AF acquisition and higher continuous frame rate. The QX100 leans heavily into casual snapshot use or travel photography, where rapid action is less of a concern.

Exploring Photography Genres: Strengths and Limits

Portrait Photography:
The Olympus with its Micro Four Thirds sensor provides pleasant skin tones and smooth bokeh, especially when combined with compatible fast primes like the 45mm f/1.8. The sensor stabilization plus face-detection autofocus help capture sharp eyes and natural textures. The QX100’s larger sensor and wider aperture at 28mm afford creamy background blur and impressive detail at close range; however, the lack of nuanced manual focus and slower AF reduce precision for critical portraits. Neither camera includes eye-detection AF, but Olympus's face detection is more consistent.

Landscape Photography:
Dynamic range and resolution matter here. The 12MP Olympus sensor delivers solid quality with pleasing color gradations but is limited by resolution compared to the 20MP QX100. The Olympus is less portable but more versatile with interchangeable lenses for wide or telephoto compositions. The QX100’s fixed zoom is convenient but can’t match specialized wide-angle lenses. Weather sealing is absent in both, so cautious use is advised outdoors. For prolonged handheld landscapes, Olympus’s sensor stabilization aids sharpness at low shutter speeds.

Wildlife Photography:
Fast autofocus and high frame rates count here, and Olympus’s E-PL1s edges out the Sony with continuous AF and 3 fps burst. The QX100 lacks the autofocus speed and tracking fidelity complex subjects demand, limiting its utility in this genre. Telephoto reach is modest on both, but Olympus users can mount longer MFT lenses. The QX100’s reach is capped at a 100mm equivalent, decent but not expandable.

Sports Photography:
Here, the Olympus’s 3 fps burst and AF tracking give it an advantage, though it’s still entry-level for sports. The slow AF and lack of continuous burst on the Sony place it firmly out of the running for fast action. Low light performance is comparable, but neither excels in dim arenas.

Street Photography:
Portability and discretion are paramount. The Sony QX100 shines in this realm - small, quiet, wallet-friendly, and usable paired with a phone already in your hand. The Olympus E-PL1s is compact but more noticeable and takes longer to deploy. Both have effective image stabilization and decent low-light capabilities for ambient street scenes.

Macro Photography:
Manual focus precision and stabilization are critical. The Olympus benefits from dedicated macro lenses and sensor stabilization for steady close-ups. The Sony’s fixed lens can focus as close as 5cm, respectable for casual macro shots but lacking optimal sharpness control.

Night and Astro Photography:
High ISO performance and long exposures matter here. The Olympus with sensor stabilization supports longer exposures handheld, useful for nightscapes. ISO noise is manageable up to 1600 but deteriorates beyond that. The QX100’s back-illuminated sensor with f/1.8 aperture at wide offers more light gathering, better noise performance, and crisper star capture but controlled manually from the phone app.

Video Capabilities:
Olympus maxes out at 720p at 30fps in Motion JPEG format, limiting for modern video work but serviceable for casual use. The Sony records 1080p at 30fps MPEG-4, delivering noticeably better video quality. Neither camera boasts microphone or headphone jacks for audio control, limiting professional video uses.

Travel Photography:
The Sony QX100’s extremely compact size and fixed zoom make it ideal for travel if paired with a smartphone (which most travelers will have). Olympus is bulkier but more versatile with lens options and superior battery life (290 vs 200 shots). Both have modest battery endurance for day-long outings.

Professional Use:
Neither camera is designed as a main professional tool. Olympus supports RAW image capture, valuable for post-processing and pro workflows. The QX100 lacks RAW support, limiting image editing latitude. Neither camera offers weather sealing or rugged build quality one expects in professional cameras.

Build Quality and Reliability: Solid Yet Unsealed

Both cameras omit weather sealing and ruggedization, so neither is suitable for shooting in challenging environmental conditions without protection. Olympus’s build feels more robust thanks to traditional design and proven MFT materials, while the QX100’s plastic and compact design feel more fragile. Both can handle casual everyday abuse but require care.

Lens Ecosystem and Compatibility

Olympus E-PL1s shines here with its Micro Four Thirds mount supporting over 100 compatible lenses ranging from high-quality primes to fast zooms and macro options widely available from Olympus and third-party manufacturers like Sigma and Panasonic. This extensibility is a major advantage for those who want to adapt system capabilities over time.

The Sony QX100’s fixed 28-100mm zoom lens limits versatility, though it covers many useful focal lengths. There is no option to swap lenses. Its advantage lies in portability rather than creative lens choice.
