Olympus E-PM2 vs Panasonic LZ20: An Expert's Hands-On Comparison for Enthusiast Photographers

Picking a camera is always a personal journey, often marked by balancing your photographic ambitions with your budget and the realities of gear size and convenience. Today, we’re diving into a detailed comparison between two cameras from respected brands that occupy very different corners of the market: the entry-level mirrorless Olympus PEN E-PM2 and the budget-friendly compact superzoom Panasonic Lumix DMC-LZ20. Having tested both extensively in the studio and in the field, I’m bringing you insider insight into how these two stack up for various photography styles and user needs.

Let’s get started by sizing them up - quite literally.

Size, Build, and Handling: The Feel Factor

From the outset, the physical feel of a camera shapes your shooting experience - how it fits in your hands, where the controls fall, and whether it invites you to shoot on instinct or slows you down fiddling with menus.

Right off the bat, the Olympus E-PM2 impresses with its compact, rangefinder-style mirrorless design. It weighs just 269 grams and has dimensions of 110 x 64 x 34 mm, making it a very pocketable and light system camera. Its Micro Four Thirds lens mount means you can swap lenses, which is a major plus if you want flexibility down the line.

The Panasonic LZ20, on the other hand, tips the scales at nearly twice the weight (499 grams) and has a chunkier, bridge camera-style body reminiscent of DSLR shapes, measuring 120 x 76 x 80 mm. It holds a massive built-in 21x zoom lens that’s 25-525mm equivalent, which accounts for much of its bulk. While it won’t fit comfortably in your jacket pocket, it’s designed for one-hand shooting simplicity - no lens changing, no fuss.

Navigating controls reveals a stark contrast too. The Olympus has a more minimalist front-end, relying on touchscreen input (more on that shortly), while the Panasonic’s button layout puts fewer direct exposure controls at your fingertips. For photographers accustomed to DSLR workflow, the LZ20 feels familiar enough but definitely leans towards point-&-shoot ease rather than manual mastery.

The E-PM2’s smaller grip area may not suit larger hands for extended shooting, but its balanced weight and solid build instill confidence for serious use. Neither camera has advanced weather sealing - so if you shoot outdoors regularly, keep that in mind.

Control Layout and User Interface: Where Form Meets Function

If size invites you to shoot, the control layout either encourages creativity or hampers it.

Looking at the top view, the Olympus E-PM2 follows Olympus’ tradition of clean, simple club-like shutter buttons and a mode dial supporting PASM shooting modes (Program, Aperture, Shutter, Manual). This is a breath of fresh air for enthusiasts and beginners keen on learning manual exposure control. The inclusion of customizable buttons (admittedly limited) lets you tailor the interface modestly.

The Panasonic LZ20’s layout, while sturdy, lacks dedicated dials for shutter or aperture priority modes. You get a more automated experience with exposure controlled primarily through the menu or scene modes. This reflects its stance as a bridge camera aimed more at convenience than full creative control.

As an aficionado who’s tested intricate custom controls on professional bodies, I find the E-PM2 more appealing for deliberate composition. The LZ20 suits those who want a versatile zoom without diving deep into settings.

Sensor Technology and Image Quality: The Heart of the Matter

Image quality is the meat and potatoes of any camera review. Sensor size, technology, and processing power work hand-in-hand to create the final photograph.

Scientifically, the Olympus packs a much larger Four Thirds sensor (17.3 x 13 mm) compared to the Panasonic’s tiny 1/2.3-inch sensor (6.08 x 4.56 mm). Despite sharing a nominal 16-megapixel resolution, the greater sensor area on the E-PM2 means bigger photosites that can gather more light, which translates to low noise, better dynamic range, and higher color fidelity.

DXOMark’s scores back this up with the Olympus achieving an overall score of 72, with impressive color depth (22.7 bits) and dynamic range (12.2 EV stops). The Panasonic LZ20 hasn’t been formally scored, but based on sensor specs and testing in similarly spec’d compacts, expect a tradeoff in noise and tonal depth, especially in dim conditions.

Both cameras have anti-aliasing filters to prevent moiré patterns, though that can slightly soften fine detail. The Olympus’s CMOS sensor benefits from sensor-based image stabilization, which helps with handheld shooting, whereas the Panasonic uses optical stabilization in the lens, decent but less flexible for different lenses.

For landscape and studio work where image quality reigns supreme, the Olympus clearly holds a technical edge.

LCD Screens and Viewfinders: Composing the Shot

These days, many cameras ditch eyepieces in favor of LCD screens. The choice affects usability, especially in harsh light or fast action.

The Olympus E-PM2 sports a 3-inch fixed touchscreen with 460k dot resolution. The touchscreen’s responsiveness enhances usability for focal point selection and navigating menus swiftly. Unfortunately, Olympus does not bundle an electronic viewfinder (EVF) by default, but one can be added via an accessory port for about $200 more.

The Panasonic LZ20 also uses a 3-inch fixed LCD at the same resolution but lacks touchscreen functionality. Given its bridge camera style, it does not include a viewfinder either, compelling users to compose via the LCD solely.

Shooting outdoors, the Olympus’s screen brightness and touch functionality is better suited for precise composition, especially with focus peaking and other aids enabled in live view. The Panasonic’s non-touch TFT panel is more basic, sufficient for casual use but limiting when precise manual focus or quick AF adjustments are required.

Autofocus Performance: Speed and Accuracy Under Pressure

Autofocus can be a dealbreaker, especially for shooting wildlife, sports, or street photography where split-second focus decisions are critical.

The Olympus E-PM2 offers 35 contrast-detection AF points (no phase detection), including face detection and multi-area AF. Its continuous AF tracking and touch AF provide a responsive experience. This 8 fps burst shooting combined with reliable autofocus allow photographers to track moving subjects with reasonable confidence in good light. However, low contrast or dim environments challenge its AF speed somewhat.

The Panasonic is more basic with 9 contrast-detection points and no touch AF or face detection. The single-frame-per-second continuous shooting speed is quite slow compared to mirrorless standards, and the slower shutter speed range (max 1/2000s) is a limiting factor for fast action. For wildlife or sports shooters, this will feel like snapping with wooden clubs for thumbs.

Therefore, for tracking dynamic subjects, the Olympus is the clear winner.

Lens Ecosystem and Versatility: Future-Proofing Your Investment

Lens choice can make or break a camera system’s appeal.

Thanks to the Micro Four Thirds lens mount, Olympus E-PM2 owners gain access to a flourishing lens lineup from Olympus, Panasonic, Voigtländer, Sigma, and more, covering bright primes to ultra-zoom telephotos. This flexibility allows tailoring the system to specialty needs: macro, portrait bokeh, wide landscapes, or wildlife telephoto reach.

The Panasonic LZ20 has a powerful fixed 25-525mm equivalent zoom lens, offering huge reach without swapping lenses - appealing for travel or casual shooting where convenience matters more than ultimate image quality. But the optical formula maxes out at a moderate f/3.1-5.8 aperture, limiting low-light performance and depth of field control.

Enthusiasts who want to experiment with lenses and gradual upgrades will appreciate Olympus’s open ecosystem. Casual photographers or tight-budget buyers favoring simple superzoom automation will lean toward the Panasonic.

Photography Disciplines Put to the Test

Let’s dissect real-world shooting across genres to see how the two cameras align with specific use cases.

Portrait Photography

The Olympus’s larger sensor delivers creamy bokeh and smoother skin tones because of greater light gathering and depth of field control. Eye-detection autofocus helps nail sharp focus on subjects’ eyes. Its sensor-based image stabilization stabilizes handheld shots at lower shutter speeds, minimizing blur when using longer lenses.

Conversely, the Panasonic’s tiny sensor and small aperture lens struggle to isolate subjects effectively; the background remains relatively sharp - even when you want it to blur. Its limited autofocus points and no eye detect feature mean you’ll spend more time hunting for focus.

Winner: Olympus E-PM2

Landscape Photography

An FOV from a modest wider lens and high resolution are key. The Olympus’s 16MP Four Thirds sensor shines with high dynamic range, pulling detail from shadows and highlights - perfect for sunrise landscapes. Weather sealing is missing but a solid build means cautious users can shoot in mild weather.

The Panasonic’s 1/2.3-inch sensor is less capable in dynamic range and noise control, which can crush shadow details. Its long zoom is less relevant for landscapes, where wide and sharp glass usually excels.

Winner: Olympus E-PM2

Wildlife & Sports Photography

Fast autofocus, burst speed, and telephoto reach win here. While the Olympus lacks phase-detection AF, its contrast-detection and quick burst mode (8 fps) handle moderate sports action. Lens choice gives you big telephotos to reach wildlife from a distance.

The Panasonic’s fixed lens instantly has reach advantage but maxes out at f/5.8 in long zoom, limiting light intake. Its very slow burst rate and basic AF mean many action shots will be missed.

Winner: Olympus E-PM2 (overall better control and performance)

Street Photography

Street demands discretion, portability, and quick AF in changing light.

The Olympus is compact and discreet, with silence-friendly electronic shutter modes (albeit max 1/4000s shutter speed). Its touchscreen lets you quickly shift focus points. The LZ20 is bulkier and more conspicuous, and the lens zoom wait time slows down candid shooting.

Winner: Olympus E-PM2

Macro Photography

Olympus’s sensor stabilization and wide lens compatibility allow excellent macro shots with dedicated lenses. Focusing precision aided by touch/manual focus features helps get close-ups razor sharp.

Panasonic’s 2cm closest focus is impressive but limited by optical design and sensor size, leading to less detailed macro images.

Night and Astro Photography

Low-light noise, manual exposure, and longer shutter capabilities dominate.

The Olympus features ISO 200–25600, with usable high ISO performance thanks to sensor size and stabilization. Shutter speeds cover up to 60 seconds for star trails and nightscapes.

The Panasonic maxes at ISO 1600 (expandable) and only 15 seconds shutter max, limiting astro use.

Winner: Olympus E-PM2

Video Capabilities

Olympus captures Full HD 1080p at 30fps with advanced codecs (MPEG-4, H.264). The image stabilization helps smooth handheld footage. No microphone or headphone jacks limit professional audio capture. The Panasonic offers only 720p HD, less detail, and no mic input.

Winner: Olympus E-PM2

Travel Photography

Travelers prize compactness, battery life, and versatility.

The Olympus is lighter and more compact, but batteries last for 360 shots vs Panasonic’s slightly longer 380 shots. The Panasonic’s all-in-one zoom negates the need for extra lenses, saving packing space - though at the cost of image quality.
