Olympus E-M1 vs. Olympus E-P2: A Hands-On Comparison for Discerning Photographers

Olympus has long been a torchbearer in the mirrorless camera market, particularly with its Micro Four Thirds system that leans heavily on compactness and versatility. Today, we take a deep dive into two very different cameras from Olympus’s recent and somewhat older lineups: the Olympus OM-D E-M1 (announced 2013) and the Olympus PEN E-P2 (announced 2010). Both share the Micro Four Thirds lens mount and lens ecosystem, yet they cater to distinct user groups and represent unique points in camera evolution.

Having spent countless hours testing and comparing cameras in varied field conditions, from studio portraits to rugged wildlife shoots, I’m eager to unpack how these two models perform in real-world scenarios. Here’s a no-fluff, technical, and user-experience driven comparison to help you decide which Olympus fits your photographic ambitions best.

First Impressions: Size, Ergonomics, and Build Quality

When you first pick up these cameras, their physical characteristics are telling. The E-M1, Olympus’s flagship Pro Mirrorless at its introduction, is solid in the hand and boasts SLR-style ergonomics - grippy, balanced, and intuitive for extended shooting. In contrast, the E-P2 embodies the stylish, rangefinder-style mirrorless aesthetic: minimalistic, compact, and lighter but also less grippy.

The E-M1 measures 130 x 94 x 63 mm and weighs a robust 497 grams, emphasizing durability and comfort for professionals or serious enthusiasts. The E-P2, by comparison, clocks in at a lighter 355 grams and much slimmer 121 x 70 x 36 mm, making it a great grab-and-go option, but one that demands a steady hand during prolonged holds.

Beyond size and weight, build quality also sets these apart. The E-M1 features environmental sealing, standing up to dust and moisture in moderate conditions - a must for landscape and wildlife photographers working outdoors. The E-P2 lacks such sealing, confining it mostly to controlled environments or casual outings where weather exposure is minimal.

Design and Controls: Top View Insights

Flipping both cameras over for a top-down look reveals a distinct difference in design philosophy. The E-M1 is built with professional controls front and center: multiple dials for exposure compensation, ISO, shooting modes, and a dedicated shutter speed dial make it clear that Olympus prioritized speed and customization here.

The E-P2 takes a minimalist approach: fewer physical controls, a more “clean” design, and reliance on menu diving for many settings that the E-M1 offers on the fly. For photographers focused on street shooting or casual travel, this minimalism might be appealing because it draws less attention and simplifies operation. However, in fast-paced or complex scenarios like sports or wildlife, the E-M1’s control interface proves a decisive advantage.

Sensor and Image Quality: A Quantum Leap

At the heart of image quality is the sensor, and here the E-M1 makes huge strides forward from the older E-P2. Both cameras employ Micro Four Thirds CMOS sensors with identical physical dimensions: 17.3x13 mm and a resulting 2.1x focal length crop factor (equivalent to half of full-frame). But their resolution and sensor technology differ markedly.

The E-M1 sports a 16MP sensor utilizing Olympus’s TruePIC VII processor, delivering:

• Maximum resolution: 4608 x 3456 pixels
• Greater dynamic range of 12.7 EV (DXO mark data)
• Improved color depth (23.0 bits)
• Much better high ISO performance with a low-light ISO rating of 757 (DXO scores)

On the flip side, the E-P2’s 12MP sensor, powered by TruePic V, achieves:

• Resolution of 4032 x 3024 pixels
• Dynamic range around 10.4 EV
• Lower color depth at 21.5 bits
• Lower usable high ISO ceiling with ISO 6400 max and a DXO low-light ISO around 505

In practical terms, the E-M1 delivers cleaner images with richer details, better color fidelity, and significantly less noise at ISO 1600 and above. For portrait and landscape photographers where detail and tonal nuance matter hugely, this advancement is palpable.

The Rear LCD and Viewfinder Experience

On the rear interface front, Olympus made interesting choices that impact usability across disciplines.

The E-M1’s 3-inch tilting touchscreen panel offers 1,037k dots, granting flexibility in composition - especially handy for macro, street, and video shooting - and direct touch AF point selection. This touchscreen implementation works well in the field and speeds up workflow by reducing menu twiddling.

Meanwhile, the E-P2 pivots on simplicity with a fixed 3-inch screen, but only 230k dots with HyperCrystal LCD technology and anti-reflective coating. While the AR treatment helps visibility in bright conditions, the lower resolution and lack of tilt limit framing flexibility and tactile control. Plus, there’s no touchscreen interface.

Regarding the viewfinder, the E-M1 integrates a bright electronic viewfinder (EVF) boasting 2,360k dots, 100% coverage, and 0.74x magnification, critical for precise composition and autofocus in various lighting scenarios. The E-P2 has no built-in EVF and relies entirely on the rear LCD or an optional external EVF accessory, which adds bulk and cost.

Autofocus Systems: Speed and Precision in Action

Autofocus can make or break a shoot, and this is a domain where the E-M1 truly shines relative to the E-P2.

Olympus E-M1 autofocus:

• 81 autofocus points with hybrid contrast and phase detection
• Face detection and continuous AF tracking
• Touch AF on screen
• Selective, multi-area and center AF modes
• Support for AF bracketing and focus stacking (essential for macro and landscape photographers)

Olympus E-P2 autofocus:

• Only 11 AF points using purely contrast detection AF
• Face detection available, but no continuous AF tracking
• No touch-based AF control
• Limited AF area modes (multi-area and selective, but no center weighted)
• No focus bracketing or stacking features

For wildlife and sports photography, where swift and accurate subject tracking is essential, the E-M1’s hybrid AF system coupled with 10fps continuous shooting (versus 3fps on the E-P2) makes it a natural choice. The E-P2’s AF struggles with fast-moving targets, and its slower response hampers capturing fleeting moments.

In the Field: Pros and Cons by Photography Genre

Through exhaustive field testing across genres, here’s what stands out about each camera’s real-world performance.
