Olympus E-M10 II vs Panasonic LZ20: A Hands-On Comparison of Two Distinct Digital Cameras

When it comes to stepping into the world of digital photography, the choices can be bewildering. Cameras come in bewildering variety - ranging from compact superzooms to serious mirrorless systems. Today’s comparison pits two very different cameras from respected Japanese brands: the Olympus OM-D E-M10 II mirrorless and the Panasonic Lumix DMC-LZ20 superzoom bridge camera. Each represents a different philosophy and user need, so our goal is to explore, through the lens of practical field-testing and technical analysis, which situations each camera is best served for.

Having tested thousands of cameras over my 15+ year career, I’ll break down these two across multiple photographic disciplines and real-world usage aspects. My intent is to provide you with an informed, balanced look that respects both the specs sheet and lived experience. Let’s dive in.

First Impressions and Ergonomics - How Do They Feel in Hand?

At first glance, and handling both side-by-side, these two cameras offer very different tactile experiences. The Olympus E-M10 II sports a classic SLR-style mirrorless body, compact yet solid. Meanwhile, the Panasonic LZ20 embraces the "bridge camera" concept - a blend of DSLR-esque looks with a fixed superzoom lens.

The Olympus body measures approximately 120x83x47mm and weighs 390g without lens, making it nimble and easy to tuck into day bags or even larger pockets if you’re sporting a pancake lens. Its magnesium alloy build gives a sturdy and professional feel - though it lacks weather sealing, which would have been a welcome addition for adventurous outdoor shooters.

Controls on the E-M10 II are well-laid out with dedicated dials for shutter speed, exposure compensation, and an intuitive menu system navigable with the small but effective rear dial and buttons. As you can see from the top-on view, the control placement is thoughtful, aligning well with mirrorless ergonomics norms:

The Panasonic LZ20 feels quite different - bigger, heavier at 499g, and chunkier due to its protruding fixed zoom lens housing. It lacks an electronic viewfinder - a notable omission if you’re used to composing through an eyepiece in bright sunlight. Instead, composition relies on the fixed 3-inch LCD screen with lower resolution.

While the LZ20’s grip is molded plastic that feels less premium, it’s still secure enough for casual shooting. Being a bridge camera, its interface is simplified - fewer physical controls, no touch screen - aimed at ease of use for entry-level or casual users.

In sum: Olympus E-M10 II is designed with enthusiasts in mind wanting control, build quality, and portability; Panasonic LZ20 is more casual, more “point-and-shoot” in style, though with a long zoom reach.

Sensor Specifications and Image Quality - The Heart of the Camera

The fundamental difference from the start: sensor size and type.

The Olympus E-M10 II uses a micro four-thirds (17.3x13 mm) CMOS sensor with TruePic VII processor, delivering 16MP resolution. Meanwhile, the Panasonic LZ20 sports a much smaller 1/2.3-inch CCD sensor, also 16MP.

Sensor size vastly impacts image quality potential, and our lab measurements bear that out. The E-M10 II’s 224.9mm² photosensitive area is nearly 8x larger than the LZ20’s 27.7mm² sensor. Larger sensors collect more light, yield less noise, and benefit dynamic range - critical for nuanced tones in shadows and highlights.

Analysis through DxO and in-field testing confirms the E-M10 II’s superiority in:

• Color depth: 23.1 bits vs Panasonic’s untested but known lower performance
• Dynamic range: 12.5 stops capturing gradations in bright sky and shadow detail alike
• Low light ISO: Effective noise control up to ISO 800+ enabling cleaner night shots

In contrast, the Panasonic LZ20 exhibits more noise and less detail retention in low light - what you’d expect of typical small sensor superzooms. While it can deliver respectable images for daylight snaps and zoomed-in compositions, pushing beyond native ISO 1600 rapidly diminishes quality.

The Olympus also shoots RAW files, giving post-processing flexibility, whereas Panasonic only delivers JPEGs, which limits advanced editing.

If image quality is a priority - especially for portraits, landscapes, or professional uses - the E-M10 II’s sensor advantage is enormous.

Autofocus System: Precision vs. Simplicity

Autofocus (AF) performance is critical for nearly every photography genre. Here, Olympus aligns with enthusiast expectations: 81 contrast-detection AF points, face detection, continuous AF, touch AF, and selectable AF modes. The system is responsive and accurate, though not as blisteringly fast as flagship models with phase detection.

The LZ20 is simpler, with only 9 AF points, no touch AF, and less refined tracking. But for casual use - travel snaps, distant wildlife shots - it’s passable.

We tested AF speed and tracking on both outdoors and indoors. The E-M10 II reliably locked focus on eyes in portraits, held tracking on moving subjects reasonably well, and even managed decent macro focusing speed with its 5-axis stabilization helping handhold precision.

The LZ20 often hunted under lower contrast or lower light, and fine-focused close-ups required patience. Its continuous shooting is limited to 1fps, limiting the ability to capture peak action moments.

For sports, wildlife, or any fast-moving scenario, the Olympus autofocus system’s sophistication is a clear asset.

Build Quality, Weather Sealing, and Durability

Neither camera is weather-sealed or ruggedized to professional standards. The Olympus E-M10 II’s metal body is durable and carries a quality heft, whereas the Panasonic LZ20 is predominantly plastic.

For landscape photographers or travel shooters venturing outdoors, the Olympus’s sturdier construction fosters more confidence in variable conditions, though cautious use in rain or dust is still advisable for both.

Neither model extends into freezeproof or crushproof territory, so rugged expedition photographers should look higher.

LCD Screens and Viewfinders - Composition Aids Compared

The Olympus delivers a 3-inch tilt-angle touchscreen LCD with a sharp 1,040k-dot resolution and a built-in electronic viewfinder (EVF) of 2,360k dots with 100% coverage and 0.62x magnification - commendable for a camera in this tier.

The EVF alone is a huge advantage in bright sunlight or for deliberate framing. The tilting touchscreen enables waist-level shots and creative angles, and the touch interface accelerates menu navigation and focus point selection.

The Panasonic LZ20 offers a fixed 3-inch 460k-dot TFT LCD with no touchscreen functionality and no EVF. Composing in direct sunlight can be challenging, and the inability to tilt cripples creative flexibility.

For composition and usability, the Olympus E-M10 II clearly outperforms, suited for enthusiasts desiring varied shooting angles and reliable framing aids.

Lens Systems and Versatility

Lens compatibility is one of mirrorless systems’ key strengths - Olympus uses the Micro Four Thirds mount with a vast ecosystem including over 100 lenses from Olympus, Panasonic, and third-party manufacturers. From ultra-wide landscapes to fast primes for portraits and super-telephoto lenses for wildlife - the choice is expansive.

By contrast, the Panasonic LZ20 is a fixed-lens bridge camera with a versatile 25-525mm (35mm equivalent) superzoom but no lens interchangeability. This zoom range is convenient for casual users wanting “one lens for all” convenience but sacrifices image quality and aperture speed compared to dedicated primes or specialist lenses.

Depending on photographic ambitions, the Olympus’s flexibility gives it staying power and adaptability far beyond the LZ20’s single zoom lens.

Burst Shooting and Video Capabilities

The Olympus maintains a respectable burst rate of 8fps for up to 24 RAW or more JPEG frames - well suited to sports, wildlife action, and event photography.

Panasonic’s LZ20 only offers a single frame per second burst, essentially limiting its usefulness for capturing fast sequences.

In video, the E-M10 II supports Full HD 1080p recording at up to 60fps with H.264 compression and clean HDMI output, though it lacks microphone and headphone jacks - somewhat limiting for serious videographers.

The LZ20 offers only 720p HD video at 30fps with Motion JPEG compression. While sufficient for casual recording, image quality and codec constraints limit professional appeal.

Neither camera supports 4K video or advanced photo modes like 4K photo capture or focus peaking.

Battery Life and Storage

Battery life on the Olympus E-M10 II is rated at around 320 shots per charge using the BLS-50 battery, which aligns with mirrorless cameras of this class. With conservative use and spare batteries, day-long shoots are feasible.

The Panasonic LZ20 boasts slightly longer endurance at 380 shots per charge, partially helped by its fixed lens and smaller sensor.

Both cameras rely on a single SD/SDHC/SDXC card slot for storage, though the Olympus’s RAW support necessitates larger cards and faster write speeds.

Connectivity, Wireless Features, and Extras

Here the Olympus again edges ahead - offering built-in Wi-Fi for wireless image transfer and remote camera control using a smartphone. This is a boon for travel and social sharing without fumbling cables.

The Panasonic LZ20 lacks any wireless connectivity, HDMI out, or USB beyond basic data transfer.

Neither camera has GPS or NFC, relatively standard for cameras aimed at casual or entry-level users.

Real-World Performance Across Photography Disciplines

Now, let’s see how these cameras perform in a variety of key photographic genres.

Portraits: Rendering Skin and Bokeh

The Olympus E-M10 II’s Micro Four Thirds sensor delivers natural skin tones with pleasing color gradations. Paired with fast prime lenses like the Panasonic 42.5mm f/1.7, creamy bokeh and sharp eye detection focus make portraits a joy. Face and eye AF assist in nailing focus, producing professional-looking results.

The LZ20’s small sensor and slower variable aperture yield flatter skin rendering with more noise in imperfect light. Background blur is minimal at telephoto max, with more pronounced depth of field - unsuitable for artistic portraiture.

Landscapes: Detail and Dynamic Range

The Olympus’s 16MP sensor and micro four-thirds lenses capture sharp details with strong dynamic range - preserving sky textures and shadow nuances in challenging scenes. Weather sealing is absent, so care is needed in harsh environments.

The Panasonic bridge camera can achieve wide ends but shows image softness and limited tonal gradation. The longer zoom helps capture distant scenes but at resolution and quality costs.

Wildlife: Autofocus Speed and Telephoto Reach

While the LZ20 boasts an enormous 21x zoom (25-525mm), its slow autofocus and 1fps burst make tracking erratic. Images lose detail and sharpness at longest focal lengths.

The Olympus, paired with a dedicated telephoto lens (300mm equivalent or more via adapters), offers faster, more repeatable AF tracking and higher image quality. Its faster burst and superior lens options make it suited for wildlife enthusiasts aiming for action and quality.

Sports: Tracking and Frame Rates

8fps burst and reliable AF on the E-M10 II allow capturing decisive moments in moderately fast sports.

The LZ20 lacks the continuous shooting frame rate and refined AF needed for sports, limiting it mostly to static or slower-paced situations.

Street Photography: Discreteness and Portability

The Olympus’s small form factor and silent electronic shutter excel here, helping capture candid moments without drawing attention. The tilting screen facilitates shooting from hip or unusual angles.

The LZ20’s size, lack of EVF, and louder zoom mechanism reduce discretion. Its handling is bulkier and less nimble in urban maneuvers.

Macro Photography

The Olympus combined with macro M.Zuiko lenses yields impressive close-up detail and focusing precision with 5-axis stabilization assisting handheld shots.

The LZ20 claims a close focus range (2cm), but image quality and focusing speed are limited. Macro enthusiasts will prefer dedicated lenses.

Night and Astrophotography

The Olympus’s larger sensor, extensive exposure controls, and higher ISO capabilities allow for creative night shots and basic astrophotography. The silent shutter helps reduce vibrations.

The Panasonic struggles in low light, with noise and limited manual controls constraining creative night work.

Video Recording

The E-M10 II’s 1080p 60fps video is competitive for enthusiasts wanting quality footage, though no microphone jack limits pro use.

The LZ20’s 720p video is suitable only for casual home movies.

Travel Photography: Versatility and Battery

Olympus provides more versatility and better image quality in a compact form but requires lens changes.

Panasonic offers an all-in-one zoom and longer battery life but at cost of image quality and bulk.
