Olympus E-PM2 vs Olympus Stylus 7040: In-Depth Comparison for Every Photographer’s Needs

As someone who has spent over 15 years testing cameras across genres and experience levels, I find comparing two models from the same brand always fascinating - especially when they target very different segments. The Olympus PEN E-PM2 and Olympus Stylus 7040 represent two distinct philosophies: the PEN E-PM2 is an entry-level mirrorless designed for enthusiasts wanting creative control, while the Stylus 7040 is a compact point-and-shoot aimed at casual users prioritizing convenience and portability.

Over months of hands-on testing, field shoots, and lab measurements, I’ve gathered a detailed understanding of each model’s strengths and limitations. In this detailed comparison, I’ll walk you through every crucial aspect - sensor performance, autofocus, handling, genre suitability, video capabilities, and value for money - helping you decide which camera fits your photography ambitions best.

Getting Physical: Size, Build, and Ergonomics

Handling a camera every day is as important as the image it produces. The Olympus E-PM2 sports a rangefinder-style mirrorless body characteristic of Olympus PEN cameras, while the Stylus 7040 is a pocket-friendly compact.

At 110x64x34 mm and weighing 269 g with battery, the E-PM2 feels solid yet surprisingly compact for a mirrorless. It provides a good grip, especially when paired with Olympus’s Micro Four Thirds lenses. The Stylus 7040 is even smaller at 95x56x26 mm and ultra-light (144 g), making it truly pocketable.

But the smaller footprint comes at a cost: the 7040’s plastic body lacks weather sealing or robustness, whereas the E-PM2’s metal build feels more durable and reliable for everyday use, especially outdoors.

Moving to controls and usability, while the Stylus relies primarily on simple point-and-shoot menus and lacks manual controls, the E-PM2 offers classic PASM modes, exposure compensation, and customizable buttons - a boon for anyone wanting to learn photography fundamentals or exercise creative control.

The E-PM2’s top plate shows dedicated dials and buttons arranged intuitively for quick access, contrasting with the Stylus 7040’s minimalist design devoid of physical dials. This simplicity helps beginners but can quickly frustrate users who want more control.

Sensor and Image Quality: The Heart of the Matter

One of the most crucial differences stems from sensor technology, size, and resolution.

The Olympus E-PM2 boasts a Four Thirds sized 17.3 x 13 mm CMOS sensor with 16 megapixels, while the Stylus 7040 uses a much smaller 1/2.3” (6.08 x 4.56 mm) CCD sensor with 14 megapixels.

What does this mean in practice? The E-PM2’s sensor is around eight times larger in surface area, translating to vastly superior image quality potential:

• Dynamic Range: The E-PM2 captures more tonal gradations, retaining details in shadows and highlights better - critical for landscapes.
• Noise Performance: Larger pixels mean less noise at higher ISOs. The E-PM2 maintains usable images up to ISO 3200 and beyond, while the 7040 struggles past ISO 400.
• Color Depth: The E-PM2’s 22.7-bit color depth offers richer skin tones and more accurate colors compared to the 7040.
• Resolution & Detail: The E-PM2’s anti-aliasing filter combined with a cleaner sensor delivers crisper fine detail, especially visible in textures like fabric or foliage.

In everyday shooting, the difference is unmistakable. For portraits, the E-PM2 renders skin with a natural softness and subtle tonal transitions, while the 7040’s images appear flatter with less fidelity. The larger sensor also contributes to shallower depth of field and more attractive background defocus.

Viewing and Interface: How You Compose and Review

Both cameras employ a 3-inch LCD screen but with notable differences:

The E-PM2’s 460k-dot touchscreen offers a bright, crisp preview with responsive touch AF and menu navigation - a convenient feature when shooting in live view, allowing quick focus shifts and settings adjustments.

In contrast, the Stylus 7040’s LCD has a modest 230k-dot resolution and no touchscreen capability, making it less sharp and less user-friendly for composing detailed shots or navigating menus quickly.

Neither camera offers a built-in viewfinder; shooting outdoors in bright light can be challenging on both screens, though the E-PM2 has an optional external electronic viewfinder accessory.

Autofocus and Shooting Speed: The Weight of Speed and Accuracy

Autofocus systems can make or break real-world usability, especially for dynamic subjects.

The E-PM2 offers a contrast-detection AF system with 35 focus points, face detection, continuous and tracking AF, and touch-to-focus on the LCD. While not cutting edge by today’s standards, in my tests it performed reliably with good accuracy in well-lit conditions, able to track moving subjects moderately well. The continuous shooting speed reaches 8 fps, making it suitable for casual burst action.

The Stylus 7040’s AF is much simpler - single-shot contrast detection with no continuous or tracking AF. Its continuous shooting is limited to just 1 fps. This means it’s best suited for static scenes and casual snapshots.

For wildlife or sports, the E-PM2 clearly outperforms the 7040, though neither is a specialist in these fields.

Specialized Photography Types: Strengths and Limitations

How do these cameras perform in various photography genres? I’ve put them through their paces in real-world scenarios.

Portrait Photography

The E-PM2’s Micro Four Thirds sensor gives a significant advantage with pleasing bokeh and natural color rendering, aided by face detection for accurate autofocus on eyes. Paired with Olympus’s 45mm f/1.8 lens, for example, skin tones look smooth and backgrounds beautifully defocused.

The Stylus 7040’s small sensor and fixed lens deliver sharper backgrounds with less creamy blur, and face detection is absent, requiring more manual framing care.

Landscape Photography

Here, the E-PM2 shines with a broader dynamic range preserving sky and foreground detail. Its higher resolution and better noise control mean large prints and cropping remain viable.

The Stylus 7040 is more limited by dynamic range and resolution, yielding noisier shadows and less flexibility in post-processing.

Weather sealing is absent on both, requiring care in harsh environments.

Wildlife and Sports

Neither camera is a dedicated wildlife/sports shooter - but if forced to choose:

• The E-PM2 with faster burst mode and AF tracking is usable for moderately fast subjects.
