Olympus E-P2 vs Panasonic ZS45: A Detailed Comparison for Discerning Photographers

Photography gear is deeply personal to me. Over my 15+ years testing cameras across genres - from landscapes in Iceland to wildlife safaris in Kenya - I’ve learned that choosing the right camera depends not just on specs, but on your style, subject matter, and priorities. Today, I’m diving into two very different offerings from Olympus and Panasonic: the 2010 Olympus PEN E-P2 and the 2015 Panasonic Lumix DMC-ZS45. Each serves a distinct niche, yet both appeal to enthusiasts wanting compact, capable cameras with a respectable feature set.

I’ll break down their real-world performance, technical strengths, and limitations, grounded in hands-on testing and my experience with hundreds of mirrorless and compact cameras. This comparison will help you understand which model suits your photographic dreams, whether it’s portraits, travel, or everyday snapshots.

First Impressions: Design, Handling, and Ergonomics

Let’s start with what you feel first - the body, size, and control layout. These cameras represent two different design philosophies: the Olympus E-P2 is a rangefinder-style mirrorless with interchangeable lenses, while the Panasonic ZS45 is a fixed-lens, travel superzoom.

The Olympus E-P2 feels solid and compact for a camera with interchangeable lenses. Its classic retro styling, inspired by film rangefinders, is not just cosmetic - the grip and button placement suggest a tool designed for thoughtful photography. At 355 grams and dimensions of 121x70x36 mm, it strikes a nice balance - you get the heft that inspires confidence without being bulky. The E-P2 is a bit thicker due to its Micro Four Thirds mount.

The Panasonic ZS45 is more diminutive: light at just 249 grams and smaller at 108x60x32 mm. It’s designed for portability and effortless travel photography. The body’s compactness allows easy one-handed use and fits neatly in a jacket or handbag pocket.

For photographers prioritizing ergonomics and tactile control, the E-P2’s dedicated dials for shutter speed and aperture, plus its physical buttons, offer a much more immersive experience. The ZS45’s smaller controls feel crisp but can be fiddly for larger fingers, and its lack of manual focus ring reminds you this is a point-and-shoot oriented device.

Top-Down View: Controls at Your Fingertips

Looking at these cameras from above gives you insight into workflow speed and usability. I’ve often found that quick access to key settings can mean the difference between missing a moment and capturing it beautifully.

The E-P2’s top plate is clean but purposeful: an exposure compensation dial, shutter speed ring, and a dedicated on/off lever make manual shooting a breeze. However, there’s no built-in electronic viewfinder (EVF); Olympus offered an optional add-on, but the absence of a native EVF felt limiting when shooting in bright daylight.

In contrast, the ZS45 opts for simplicity: a top shutter release surrounded by a zoom rocker and a mode dial. Its design emphasizes intuitive zooming and shooting, rather than manual control. Not having any physical exposure compensation dial or dedicated ISO control slows down those wanting granular settings, but the camera’s automatic modes help compensate for casual users.

Personally, I appreciate the E-P2’s approach if you crave full manual control and rapid adjustments. For casual walk-around shooting or travel where speed and lightness dominate, the ZS45’s simplicity shines.

Sensor and Image Quality: The Heart of the Matter

The sensor defines image quality, and here the gap between the cameras is stark.

The Olympus E-P2 uses a Four Thirds sized sensor measuring 17.3x13 mm, offering 12-megapixels with a crop factor of 2.1x. This larger sensor means better noise control, wider dynamic range, and richer color depth. It’s the same sensor size as many Olympus and Panasonic mirrorless cameras, renowned for punchy colors, sharpness, and decent ISO performance up to 1600 or 3200 in practical use.

The Panasonic ZS45 has a much smaller 1/2.3” sensor at 6.08x4.56 mm, packing 16 megapixels. This smaller sensor with a 5.9x crop factor is standard in compact superzooms but inherently limits low-light performance and dynamic range because fewer photons hit each pixel. Noise increases dramatically at higher ISOs, and shadow recovery is more limited.

In my testing, the Olympus E-P2 delivered cleaner images at ISO 800, with better shadow details and color fidelity. The ZS45 produces good results in bright daylight, especially for travel snaps but struggles noticeably in indoor or dim conditions.

If image quality - and especially noise handling or dynamic range - is your priority, the E-P2’s sensor takes this round decisively. However, the ZS45’s sensor allows the incredible zoom range that would be impossible on a larger sensor camera of similar size.

The Rear LCD: Composing and Reviewing Your Shots

A good LCD screen makes shooting and image review enjoyable, so I compared their displays.

The Olympus E-P2 sports a 3-inch fixed HyperCrystal LCD with 230k dots resolution. It’s bright and crisp enough for composing in normal conditions but can be harder to see under strong sunlight. The lack of articulation and touchscreen limits creative angles and quick focusing.

The Panasonic ZS45 also has a 3-inch LCD but with a remarkable 1040k dots and a tilting mechanism to facilitate low- or high-angle shoots. This tilting screen is a huge advantage in street photography or macro work, where you often can’t get your eye to the finder. The higher resolution delivers sharper preview images and more pleasant navigation through menus.

Personally, I found the ZS45’s screen noticeably better for on-the-fly shooting, while the E-P2’s screen, though adequate, occasionally forced me to shade it or rely on histogram for exposure judgment.

Autofocus Performance: Speed, Accuracy, and Tracking

Autofocus can make or break your experience - especially for wildlife, sports, or street photography where subjects move unpredictably.

The Olympus E-P2 relies on contrast-detection AF with 11 focus points. It offers face detection and allows AF-multi area selection, but notable is the lack of continuous AF tracking, making it less suited for fast action. Manual focus is possible, aided by focus peaking on compatible lenses, which Olympus integrates well.

By 2015 standards, the Panasonic ZS45’s AF is more advanced: 21 focus points, continuous AF tracking, center-weighted AF, and face detection. The ZS45’s contrast-detection system locks focus quickly in good light and follows moving subjects better, benefiting from updated processor tech.

In practice, I found the ZS45’s AF quicker and more responsive for dynamic subjects like kids running or birds fluttering. The E-P2 excels with static subjects where you can engage manual focus or fine-tune AF points precisely.

Lenses and Zoom Versatility

Lens availability and focal length options often dictate what kinds of photography you can pursue.

The Olympus E-P2 uses the Micro Four Thirds mount, meaning it supports a vast ecosystem of over 100 lenses, from ultra-wide 7mm fisheye to telephoto 300mm primes and zooms. This breadth allows you to tailor your kit precisely: fast primes for portraits, macro lenses, wide-angle for landscapes, or telephoto for wildlife.

The Panasonic ZS45 has a fixed lens with a staggering 20x zoom ranging from 24-480 mm equivalent focal length and an aperture range of f/3.3-6.4. This superzoom lens is versatile for travel and general photography, offering everything from wide landscapes to distant details without changing lenses.

Here, the choice depends on your priorities: If you enjoy swapping lenses and crafting specific looks - bokeh-rich portraits or macro - E-P2’s mount opens doors. If portability and single-lens convenience are key, the ZS45’s all-in-one lens is convenient but optically compromises at telephoto extremes and wider apertures.

Burst Rates and Continuous Shooting: Catching the Decisive Moment

Sports and wildlife photographers live or die by their camera’s frame rate.

The Olympus E-P2 manages 3 frames per second (fps) continuous shooting, adequate for moderate action like portraits or posed events but too slow for rapid bursts.

In contrast, the Panasonic ZS45 offers a faster 10 fps burst, allowing better chances to capture perfect timing - say a street candid smile or a bird taking flight. While the small buffer limits very long bursts, its speed is respectable for a compact snapper.

For outright speed, the ZS45 takes the crown, but with a tradeoff in image buffer size and fewer manual control options during bursts.

Video Capabilities: Beyond Stills

Though primarily photographers, many users want solid video from their cameras.

The Olympus E-P2 records video at 1280x720 (HD) at 30fps with Motion JPEG compression - quite dated by today’s standards. It lacks microphone or headphone ports and offers minimal video control.

The Panasonic ZS45 records full HD 1920x1080 at 30fps in MPEG-4 format. While still modest compared to modern 4K cameras, it delivers better resolution and smoother video. Like the E-P2, it lacks audio input/output ports and advanced video features.

Neither camera targets professional video creators, but casual videographers will appreciate the ZS45’s sharper footage and better zoom during recording.

Battery Life and Storage Options

Battery endurance is crucial when out shooting all day.

The Olympus E-P2 uses a BLS-1 lithium-ion battery with a rated life of roughly 300 shots per charge.

The Panasonic ZS45 delivers moderately better battery endurance with about 350 shots, aided by smaller sensor and screen power draw.

Both use standard SD or SDHC cards with single slots. The ZS45 adds compatibility with SDXC and includes internal memory, handy in emergencies.

From my travel outings, the ZS45’s slightly longer battery life and smaller charger footprint align well with lightweight packing, though carrying spares remains essential with either camera.

Connectivity and Extra Features

Modern cameras lean on wireless features - unfortunately, the E-P2 has none.

The Panasonic ZS45 includes built-in Wi-Fi for easy image transfer and remote control via smartphone apps - a major plus for social sharing or remote shooting.

Neither offers Bluetooth, NFC, GPS, or advanced environmental sealing.

Portrait Photography

The Olympus E-P2 with a fast Micro Four Thirds prime excels at skin tone reproduction and creamy bokeh. Facial detail is crisp, and eye detection works well though requires patience.

The ZS45’s smaller sensor limits shallow depth of field and bokeh smoothness. Though it tracks faces accurately, portraits feel flatter and less vibrant.

Landscape Photography

E-P2’s wider dynamic range captures shadow details and sky gradients gracefully. The 12MP resolution and sturdy sensor enable richer post-processing latitude.

ZS45 is decent in bright daylight but loses detail in shadows and highlights.
