That extra heft accommodates the all-in-one 25-400mm zoom lens, delivering immense focal flexibility but compromising portability. It’s more of a travel-friendly powerhouse - but less pocketable or lightweight.

Moving to control layouts, the Olympus opts for classic dials and a simple top plate with adequately spaced buttons, appealing to photographers who want full manual control with intuitive placement.

The Panasonic, meanwhile, balances between bridge camera ergonomics and mirrorless-style control, incorporating a deeper ergonomic grip and an abundance of customizable buttons. For one-handed zoom and focus, the lens barrel is well-rubberized and responsive.

Bottom line: If you prize a compact, weather-sealed body with traditional controls, the Olympus E-M5 shines. For a versatile all-in-one with long reach, the FZ1000 II is a more substantial but still manageable grab-and-go solution.

Under the Hood: Sensor Technology and Image Quality Insights

The heart of any camera is its sensor and image processing engine. Both cameras deploy CMOS sensors but with different sizes and resolutions, impacting detail, dynamic range, and low light performance.

• Olympus E-M5: Uses a Four Thirds 17.3 x 13 mm sensor with a 16MP resolution. Output maxes at 4608 x 3456 pixels. The micro four-thirds format trades off sensor size for compactness and system flexibility, employing the TruePic VI processor.

• Panasonic FZ1000 II: Packs a larger 1-inch type 13.2 x 8.8 mm sensor at 20MP resolution, maxing at 5472 x 3648. The sensor is BSI-CMOS (backside illuminated), which typically helps with low-light sensitivity and dynamic range.

Hands-on, the Olympus’s sensor offers excellent image quality for its class, capturing crisp detail with good dynamic range (around 12.3 EV measured). Noise holds up reasonably to ISO 1600; beyond 3200 ISO, grain and smoothing become noticeable.

The Panasonic’s 1” sensor, although smaller than most APS-C or full-frame sensors, surprisingly delivers sharp images with good color depth and somewhat better high ISO performance compared to the Olympus, especially considering its zoom lens's varied aperture range (f/2.8-4.0).

However, the inherent crop factor means the Olympus benefits from interchangeable lenses and a versatile Micro Four Thirds lens ecosystem.

User Interface and Rear Screen Performance

Both cameras feature fully articulating 3-inch touchscreens, but differences in resolution and interface responsiveness affect real-life shooting.

• Olympus E-M5 sports a 610K-dot tilting touchscreen, providing touch control over focus and menu navigation. The screen is crisp, though modest for today’s standards, and excels in bright light thanks to surface coatings.

• Panasonic FZ1000 II upgrades to a 1240K-dot fully articulated touchscreen, doubling resolution and allowing forward-facing selfies. The touch response is fluid and covers more angles, a boon for vlogging or tricky shooting positions.

The electronic viewfinder (EVF) on the Panasonic boasts a higher resolution of 2.36 million dots (vs. Olympus’s 1.44 million dots), providing a brighter and more detailed preview - a clear advantage for precise focusing and composition.

Autofocus and Burst Shooting: Real-World Speed and Accuracy

Autofocus performance can make or break your shooting experience, especially for fast-moving subjects in wildlife, sports, or street photography.

The E-M5 uses a contrast-detection AF system with 35 points, supporting face detection, continuous AF, and tracking. In practice, its AF is accurate, but contrast-based AF means it’s slightly slower and hunt-prone in low light or low contrast scenes.

In contrast, the FZ1000 II offers a 49-point contrast-detect AF, augmented by Panasonic’s Venus engine. This translates to faster focus acquisition and impressive tracking capabilities for a bridge camera, especially in burst mode.

Regarding shooting speed:

• Olympus E-M5 delivers 9 fps continuous shooting with autofocus - sufficient for casual action photography.

• Panasonic FZ1000 II pushes 12 fps, helping capture fleeting wildlife or sports action with more frames to select from.

The Panasonic also features advanced focus bracketing and stacking, a bonus for macro and studio shooters looking for extended depth of field.

Diving Into Photography Genres: Hands-On Field Performance

How these cameras perform for specific photography styles is pivotal.

Portraits: Rendering Skin and Detailing Eyes

The Olympus E-M5, with its Micro Four Thirds system, pairs excellently with fast prime lenses (e.g., 45mm f/1.8). This allows creamy bokeh and smooth skin tone reproduction - critical for professional portraiture.

Embedded face and eye detection perform well, but fine focus on eyes can occasionally miss in tricky light due to contrast AF.

The Panasonic FZ1000 II lacks interchangeable lenses, so while the built-in zoom goes to 400mm, wide aperture bokeh capability is limited (max f/2.8 at wide, f/4 at telephoto). Skin tones are rendered naturally but with less pleasing out-of-focus smoothing.

Landscape: Resolution and Weather Resistance

For landscapes, dynamic range and high resolution are paramount, alongside weather sealing for rugged conditions.

The Olympus’s weather-resistant build gives significant stamina in tough outdoor shooting, an advantage over the Panasonic which lacks environmental sealing.

While the FZ1000 II offers higher megapixels and a capable zoom for varied framing, the Olympus’s ability to swap lenses (wide-angle primes, tilt-shift lenses) makes it more adaptable for landscape creativity.

Wildlife: Autofocus and Telephoto Reach

Panasonic’s built-in 25-400mm zoom (equivalent) extends wildlife reach without extra lenses - huge for budget-conscious or travel wildlife photographers. Fast AF and 12 fps shooting enhance capturing fleeting moments.

Olympus requires attaching telephoto lenses that tend to be bulkier and more expensive but offer potentially superior sharpness and faster AF.

Sports: Tracking Speed and Low Light

While neither camera is a dedicated sports machine, the Panasonic’s 12 fps and faster autofocus tracking edge it out for moderate sports photography.

Olympus’s 9 fps and more limited AF speed mean it's better suited for slower-paced subjects, though its weather sealing can impress in outdoor sports environments.

Street Photography: Discretion and Agility

The Olympus's smaller size and lighter weight make it ideal for street photography - especially combined with compact primes.

The Panasonic’s larger stature and prominent lens draw more attention but compensate with longer zoom and fantastic framing versatility.

Macro: Magnification and Precision

Panasonic wins here with a minimum focusing distance of just 3 cm and focus stacking features - uncommon in this class - making it a surprisingly competent macro tool.

Olympus's lineup of macro lenses and 5-axis image stabilization support excellent hand-held close-up work, though it requires investing in lenses.

Night and Astro: High ISO and Exposure Flexibility

Olympus’s better dynamic range and low light ISO performance (up to ISO 3200 usable) paired with 5-axis IBIS stabilization is outstanding for handheld night scenes and even astro when paired with fast lenses.

Panasonic offers higher max ISO but struggles with noise beyond ISO 1600; however, its electronic shutter flexibility and 4K video (discussed below) open creative options.

Video Capabilities: Which Is a Better Hybrid Shooter?

Video is increasingly important - and here’s where Panasonic holds a clear advantage.

The FZ1000 II shoots 4K video at 30p, incorporating 4K photo modes for extracting stills from footage - ideal for wildlife or action time-sensitive shots. Optical stabilization counters camera shake well.

It also features a microphone input, enabling better audio capture, a microphone port missing on the Olympus.

The Olympus E-M5 tops out at 1080p 60fps, adequate but trailing current hybrid standards. Its 5-axis stabilization helps smooth handheld footage, yet the lack of 4K and mic port limit serious video work.

Build Quality, Weather Resistance, and Durability

The E-M5 features a weather-sealed magnesium alloy body, offering dust and splash resistance that’s vital for outdoor shooting in inclement weather.

The FZ1000 II, while sturdily built, does not have environmental sealing - a notable gap for shooting in harsh or unpredictable conditions.

Battery Endurance and Connectivity Options

Battery life is comparable:

• Olympus E-M5 rates about 360 shots per charge, typical for a mirrorless from its era.
• Panasonic FZ1000 II is rated slightly lower at 350 shots.

Neither camera supports USB charging but both use proprietary rechargeable lithium-ion packs.

In connectivity, Panasonic edges ahead with built-in Wi-Fi and Bluetooth allowing smoother remote control and image transfer. Olympus’s wireless features are limited to Eye-Fi card connectivity - a bit outdated.

Lens Ecosystem and Expandability

A major Olympus advantage is the Micro Four Thirds lens ecosystem, boasting over 100 lenses from Olympus, Panasonic, Sigma, and more - primes, zooms, macros, tilt-shifts, you name it.

Panasonic’s FZ1000 II has a fixed 25-400mm zoom lens, optimized for versatility but limiting depth of field control and optical quality compared to specialized lenses.

Price-to-Performance: Which Offers Better Value?

At launch:
