Choosing a camera is both an exciting and daunting task, especially when faced with two models from different generations, categories, and price points. Today, we’re diving deep into a direct comparison between the Olympus PEN E-PL1, a pioneering entry-level mirrorless from 2010, and the Sony Alpha A9 II, a pro-level marvel launched in 2019. I’ve tested both extensively in diverse settings - from portraits to wildlife, street photography to video work - to give you actionable insights grounded in years of camera evaluation.

This isn’t just a specs battle; it’s about how these cameras perform in the real world, where image quality, handling, autofocus sophistication, and durability shape your photographic success. Whether you’re budgeting smartly or ready to overinvest in professional gear, this review will help you decide which camera fits your style and needs.

First Look: Size, Build, and Ergonomics

Let’s start with the tactile experience - size, grip, and overall handling.

• Olympus E-PL1: This slim, rangefinder-style mirrorless camera is compact and lightweight at just 334g and nearly pocket-friendly dimensions (115x72x42mm). It’s designed for portability, favored by casual shooters and street photographers who want a subtle camera that doesn’t draw attention. The E-PL1 feels plasticky but well-built for its price and category. Its small body may feel cramped for users with larger hands or when paired with bigger lenses.

• Sony A9 II: In striking contrast, the Sony A9 II impresses with a much larger, more robust SLR-style body weighing 678g and sized at 129x96x76mm. It’s built like a tank with magnesium alloy, weather sealing, and a deep grip optimized for extended professional use. The heft is noticeable but justified by its advanced controls and ruggedness. This camera demands you to take it seriously and expects you will place reliability and ergonomics over portability.

While the Olympus wins for travel-friendly stealth, the Sony offers professional handling confidence ideal for long shoots under varying conditions.

Control Layout and User Interface: Intuitive or Intimidating?

The user interface tells you who the camera is designed for.

• E-PL1: The top plate is minimalistic, with a mode dial and shutter button dominating the ergonomics. The camera lacks an electronic viewfinder by default, meaning you rely mostly on the fixed 2.7-inch LCD screen with 230K resolution. The control scheme is basic, with limited customizable buttons, which suits beginners well but inhibits rapid manual control in demanding moments.

• Sony A9 II: Here, Sony shows its professional pedigree with a complex array of buttons, dials, and a top LCD display for shutter speed, ISO, battery status, and more. The highly detailed electronic viewfinder with an ultra-high 3.68-million-dot resolution offers 100% coverage and crisp magnification, making manual focus and critical composition precise. Touchscreen controls on the 3-inch tilting LCD add convenience. For professionals familiar with Sony’s layout, this camera promotes speed and accuracy.

If you value simplicity or are transitioning into mirrorless, the Olympus E-PL1’s layout is less intimidating, but for seasoned users needing granular control, the A9 II is a clear winner.

Sensor and Image Quality: Technology Through the Ages

At the heart of any camera is its sensor - the digital canvas that captures your moments.

• Olympus E-PL1: The E-PL1 features a 12-megapixel Four Thirds CMOS sensor measuring 17.3 x 13 mm, significantly smaller than full-frame, with a focal length multiplier of 2.1x. Image quality is serviceable for casual use but limited by lower resolution and dynamic range (measured DxO dynamic range is 10.1 EV). The sensor includes an anti-aliasing filter which can slightly soften images but reduces moiré artifacts. ISO tops out at 3200 native, with a DxO low-light ISO score of 487, illustrating modest noise control.

• Sony A9 II: The A9 II’s BSI-CMOS full-frame sensor measures 35.6 x 23.8 mm, yielding 24 megapixels of resolution for extremely detailed images with a focal length multiplier of 1.0x. While DxO scores are not available for this exact model, we know the A9 II provides excellent color depth, wide dynamic range, and outstanding low-light performance, handling ISO values up to 51200 native and 204800 boosted. The back-illuminated sensor design enhances light capture and noise reduction, crucial for professional-grade results.

In side-by-side tests, the Sony A9 II images exhibit richer color rendition, finer detail, and cleaner shadows and highlights, granting immense flexibility in post-processing. The Olympus, while decent for web use and small prints, reveals limitations in challenging lighting and large prints.

Viewing and Composing: The Importance of Display

The display is your primary tool for framing unless you prefer an EVF.

• Olympus E-PL1: The fixed 2.7-inch LCD with HyperCrystal technology offers decent visibility but is hampered by low resolution (230K dots). It struggles under bright sunlight, limiting your compositional precision outdoors. No touch capability means navigation can be slightly cumbersome.

• Sony A9 II: The 3-inch tilting LCD screen has a very high 1,440K dot resolution with touchscreen functionality, allowing quick menu navigation and touch-based focus. Complemented by the sharp electronic viewfinder (0.78x magnification), composing is reliable even in intense conditions. The full articulation supports creative shooting angles.

For photographers shooting outdoors or requiring flexibility in composition, the Sony’s interface is vastly superior.

Autofocus Systems: Speed, Accuracy, and Tracking

Autofocus (AF) can make or break a photo, especially in action, wildlife, or sports photography.

• E-PL1: This camera uses contrast-detection AF with 11 points, face detection, and single/continuous autofocus modes. While suitable for static subjects, it lags noticeably in tracking moving subjects or in low contrast environments. Its AF speed is slow by current standards - around 0.5 - 1 second focus lock time.

• Sony A9 II: The A9 II boasts a hybrid AF system with 693 phase-detection points and real-time Eye AF for humans and animals, plus 100% frame coverage. AF acquisition is near-instantaneous, with 20 fps silent burst shooting paired with continuous AF/AE tracking. Tracking accuracy and speed in my tests with fast-moving subjects (runners, birds in flight) were exceptional and rarely lost focus.

If you need to capture fast-paced subjects or demand consistent autofocus reliability, the A9 II dominates here.
