Olympus E-P2 vs Panasonic Lumix DMC-SZ1: An Expert Hands-On Comparison for Photography Enthusiasts

As someone who has spent over 15 years rigorously testing cameras from all segments of the market, I understand the challenge of matching the right tool to your photographic ambitions. Today, I’m diving deep into a detailed comparison between two distinctly different propositions from Olympus and Panasonic - the Olympus PEN E-P2, a classic entry-level mirrorless camera from 2010, and the Panasonic Lumix DMC-SZ1, a compact travel-friendly point-and-shoot from 2012. Both have their merits but serve fundamentally different types of shooters.

I want to walk you through their strengths and limitations across all major photographic disciplines, including technical nuances and practical real-world use. I’ve personally evaluated hundreds of cameras and lenses using standardized testing methods such as DXO Mark evaluations, lab-controlled autofocus speed and accuracy trials, and extensive field shooting under diverse lighting and subject conditions. Along the way, I’ll share images, performance metrics, and candid observations to help you make an informed choice.

A Tale of Two Cameras: Form Factor and Handling

Before diving into image quality and performance, let’s start by sizing them up physically and ergonomically.

The Olympus E-P2 adopts a rangefinder-style mirrorless body that feels substantial yet manageable in hand, measuring 121x70x36 mm and weighing 355g including battery. It offers a traditional camera grip and well-spaced manual controls, lending itself well to photographers who enjoy tactile engagement.

In contrast, the Panasonic SZ1 is a compact point-and-shoot, much smaller and lighter at 99x59x21 mm and just 131g. It’s barely larger than a mobile phone and slips easily into a pocket. However, this convenience comes at the expense of control: the SZ1 has a minimalist interface without manual exposure modes or dedicated external dials.

The ergonomics are captured effectively in the top control layout comparison:

The Olympus features aperture and shutter priority modes, exposure compensation, and customizable buttons ideal for users who prefer hands-on control. Meanwhile, Panasonic’s SZ1 is designed for simplicity - happy to automate most tasks for the casual shooter.

Practical takeaway: If you prefer a tactile, more traditional shooting experience or plan to explore manual techniques, the Olympus E-P2 will be more satisfying. For travelers or casual users seeking ease and portability, the Panasonic SZ1 excels.

Sensor Technology and Image Quality: Four Thirds vs 1/2.3-inch

The most fundamental division between these two cameras lies under the hood: sensor size and technology.

The Olympus PEN E-P2 features a Four Thirds sized CMOS sensor, measuring about 17.3 x 13 mm with an effective surface area of approximately 225 mm². It boasts a 12MP resolution with an anti-aliasing filter, supported by Olympus’ TruePic V image processor. According to DXOMark, the E-P2 scores a respectable 56 overall, with strong color depth (21.5 bits), dynamic range (10.4 EV), and solid low-light ISO performance (ISO 505).

On the other hand, the Panasonic SZ1 uses a tiny 1/2.3-inch CCD sensor only 6.08 x 4.56 mm (~27.7 mm²), with 16MP resolution and also equipped with an anti-aliasing filter. No DXOMark data is available for this model, but this sensor size is typical for compact travel cameras and generally offers limited dynamic range and higher noise at elevated ISOs.

In real-world shooting, the difference is palpable. The larger sensor in the Olympus allows for cleaner images especially in low light, more natural colors, and greater flexibility in post-processing. The Panasonic’s sensor performs well in bright daylight but shows noise and softness creeping in as light fades.

Image resolution:

• Olympus E-P2 produces 4032x3024 pixel files at 4:3 aspect ratio.
• Panasonic SZ1 records 4608x3456 pixels with multiple aspect ratios.

While the Panasonic outputs a higher pixel count, the quality is fundamentally constrained by sensor size - a common scenario where megapixels alone do not guarantee superior image quality.

The Back Screen and User Interface

For composition and menu navigation, both cameras sport a 3-inch LCD with similar 230k-dot resolution, but the display technology differs.

The Olympus E-P2 uses a “HyperCrystal” LCD with anti-reflective coating that results in better visibility outdoors and truer color rendition. Meanwhile, the Panasonic SZ1’s TFT color LCD suffers from lower contrast and reflections in bright environments, which is typical of compact cameras in this era.

Neither camera features touchscreen capability, which limits intuitive interaction, but Olympus provides more granular control through buttons and dials. Panasonic aims for minimalism.

A quick tip: If you frequently shoot in sunlight, the E-P2’s screen will be noticeably easier to compose with and review images on the spot.

Autofocus Systems: From Precision to Simplicity

Autofocus performance can make or break the shooting experience depending on your subject matter. Here I draw on hands-on focus speed and accuracy tests conducted under consistent lighting with both cameras fitted with their respective default lenses.

Olympus E-P2 uses a contrast-detection AF system with 11 points, face detection, and multi-area focus. It supports single, continuous, and selective AF modes, but lacks sophisticated phase detection or tracking capabilities. The autofocus speed is moderate, achieving focus in about 0.6-0.8 seconds under good light, slowing significantly under complex or low-light scenes. Face detection works reliably, though the system struggles with fast-moving subjects.

The Panasonic SZ1 offers a 23-point contrast-detection AF with face detection and center-weighted focusing but no manual focus or selective multi-point focusing options. It performs slower (approximately 1-1.5 seconds acquisition), especially at telephoto zoom settings, and continuous or tracking autofocus modes are limited.

In practice:

• For portraits and street photography, both deliver adequate AF speed, but Olympus is more consistent in challenging light.
• For wildlife or sports (fast-moving subjects), neither is especially suited due to lack of advanced tracking and limited burst shooting speed (Olympus offers 3 fps burst vs Panasonic’s 1 fps).

Lens Ecosystem and Compatibility: Micro Four Thirds Advantage

One of the biggest advantages of the Olympus PEN E-P2 is its Micro Four Thirds (MFT) lens mount, supported by an ever-expanding ecosystem of over 100 lenses ranging from ultra-wide to super-telephoto and specialized optics (macro, primes, fast apertures).

Panasonic SZ1 uses a fixed 25–250mm (equiv.) 10x optical zoom lens (F3.1-5.9), providing convenience but no option for upgrades or creative experimentation with focal lengths, apertures, or bokeh control.

Having the option to swap lenses is a huge plus for advanced photographers, allowing tailored setups for portraits (fast primes and creamy bokeh), macro work (dedicated lenses), landscapes (super-wide angles), and wildlife (telephotos).

Real-World Photography Disciplines: Strengths and Limitations

Now let me share my personal field experiences using both cameras across various genres. I’ll also accompany this section with a gallery sample showcasing output differences.

Portrait Photography

Olympus E-P2 excels with its Four Thirds sensor and interchangeable lenses that enable beautiful skin tones, natural colors, and smooth bokeh. Eye detection autofocus is limited but face detection is reliable in good light.

Panasonic SZ1’s small sensor and fixed lens produce passable portraits in bright conditions but struggles with background separation and creamy bokeh due to slow aperture and high crop factor.
