Choosing the right camera is a journey that depends a lot on what you shoot, how you work, and what features really matter in the field. Having personally tested thousands of cameras over 15 years, I’m sharing a detailed, unbiased comparison between two very different but intriguing models: the Olympus Stylus 550WP (hereafter Olympus 550WP) and the Panasonic Lumix DMC-GX85 (Panasonic GX85). These cameras serve vastly different audiences but sometimes those lines blur, and it’s worth digging deep to see how they stack up.

In this comparison, I focus on real-world use, technical capabilities, and which camera might serve your photographic passions best - from landscapes and portraits to wildlife, sports, street, macro, night, video, and professional work. Let’s dive in.

First Impressions: Design, Build, and Ergonomics

Before even touching pixels or autofocus points, how a camera feels in your hands can make or break your shooting experience.

Olympus 550WP is a compact, rugged point-and-shoot announced in 2009 with a waterproof design (though not fully waterproof rated - more on that later). It’s tiny, lightweight (167g), and built with casual shooters and outdoor adventurers in mind.

Panasonic GX85, introduced in 2016, is a Micro Four Thirds mirrorless camera aimed at enthusiasts and prosumers. It’s a "rangefinder-style" camera with a robust body and a heftier 426g weight, reflecting many more physical controls and complex features.

Sensor and Image Quality: Comparing Core Capabilities

The heart of any camera is its sensor, which directly influences image sharpness, detail, dynamic range, and noise performance.

The Olympus 550WP features a 1/2.3” CCD sensor measuring approximately 6.08 x 4.56 mm (sensor area ~27.7 mm²) at 10 megapixels. This is typical for compact cameras of its era but small compared to modern standards.

Meanwhile, the Panasonic GX85 offers a Micro Four Thirds CMOS sensor sized 17.3 x 13 mm (~224.9 mm²), packing 16 megapixels without an anti-aliasing filter. This sensor boasts much larger surface area, better light-gathering ability, and modern performance.

Image Quality in Practice

• Dynamic Range: The GX85’s larger sensor outperforms the Olympus in handling wide brightness ranges. I tested landscape scenes with strong sunlight and shaded foregrounds - the GX85 preserved shadow details remarkably well, while the 550WP struggled with clipped highlights and muddy shadows.

• Resolution: The GX85’s 16MP resolution provides greater detail and cropping flexibility versus the Olympus’s modest 10MP. This matters especially if you crop or print large.

• High ISO/Low Light: The Olympus tops out at ISO 1600 but with visible noise and softness at the top end. The GX85 achieves usable images up to ISO 3200 or beyond owing to advanced sensor tech and noise reduction, critical for night, event, and indoor photography.

Summary:

• Olympus 550WP: Sensor suitable for daylight casual shooting; limited dynamic range and low-light performance.
• Panasonic GX85: Larger sensor delivers superior image quality, dynamic range, and low-light versatility.

Autofocus and Performance: Speed, Accuracy, and Tracking

How quickly and accurately a camera focuses impacts your ability to capture fleeting moments - especially for sports, wildlife, and street photography.

• Olympus 550WP: Has a single contrast-detection AF system with no face or eye detection, limited to center-weighted focusing. No continuous or tracking AF exists. For still subjects in good light, this is passable, but moving subjects or low light focus quickly becomes a chore.

• Panasonic GX85: Equipped with 49 contrast-detection AF points and advanced tracking, including face detection and continuous AF. It supports fast locking focus, wide AF coverage, and impressive tracking accuracy.

Real-world Testing:

When photographing moving subjects, I found the GX85’s AF system reliable and much faster, especially for street photography where spontaneous focusing is critical. The 550WP often hunted for focus, resulting in missed shots.

Continuous burst rate differences also stand out:

• Olympus 550WP doesn’t support continuous shooting mode.
• Panasonic GX85 offers bursts up to 8 fps, allowing sequences for sports and wildlife.

Summary:

• Olympus 550WP: Basic AF for casual shots only; not suitable for action.
• Panasonic GX85: Advanced, fast AF with continuous and tracking modes excel across genres.

Display and Viewfinder: Framing and Reviewing your Shots

The ability to compose and review images comfortably influences shooting experience and accuracy.

• Olympus 550WP has a fixed 2.5" LCD with low 230k pixel resolution and no touchscreen.
• Panasonic GX85 features a 3" tilting touchscreen LCD with 1040k resolution and a high-resolution electronic viewfinder (EVF) at 2.76 million dots with 100% coverage.

Practical Notes:

• The GX85’s EVF offers eye-level shooting, stable framing, and detailed previews including live exposure simulation.
• The tilting touchscreen is fantastic for video, street photography, or awkward angles.
• The 550WP’s small, fixed LCD is usable but can feel cramped for image review, especially in bright light.

Summary:

• Olympus 550WP: Basic screen, limited review accuracy.
• Panasonic GX85: High-res EVF plus versatile touchscreen greatly improve framing and reviewing.

Lens Compatibility and Ecosystem

Lens choice defines creative potential. A fixed lens limits you; interchangeable lens systems expand possibilities.

• Olympus 550WP has a fixed 38-114 mm equivalent (3x optical zoom) lens with aperture ranging F3.5-5.0. It’s convenient but restricting for diverse subjects and low-light work.

• Panasonic GX85 uses the Micro Four Thirds mount, with over 100 native lenses available - including primes, zooms, macro, and specialty optics from Panasonic, Olympus, and third parties. Its 2.1x crop factor offers telephoto reach with many affordable lenses.

Implications:

Whether you want spectacular portraits with fast primes or wildlife reach with super-telephoto zooms, the GX85 enables that flexibility. The Olympus is more of a grab-and-go snapshot system with limited creative control.

Build Quality and Durability: Weather Resistance and Robustness

• Olympus 550WP is marketed for rugged use with weather sealing, shock resistance, crush and freeze proof features typical of a tough compact. However, it is not waterproof, so keep it away from prolonged wet conditions.

• Panasonic GX85, while well built with a solid magnesium alloy top plate, lacks weather sealing. It requires more care in challenging environments but can handle typical daily use well.

Summary:

• Olympus 550WP offers entry-level ruggedness for active casual use.
• Panasonic GX85 is more delicate but built for serious photography indoors and fair weather outdoor use.

Battery Life, Storage, and Connectivity

• Olympus 550WP battery life isn’t officially specified. Given its small sensor and no EVF, expect modest endurance. It uses xD-Picture Card, microSD, or internal storage with only one slot.

• Panasonic GX85 provides 290 shots per battery charge per CIPA testing - typical for mirrorless. It accepts standard SD/SDHC/SDXC cards with one slot and supports built-in wireless connectivity (Wi-Fi) for image transfer and remote control. It also has HDMI output for external monitors.

For continuous shooting and longer sessions, the GX85’s battery is more manageable, and the versatile storage options are preferable.

Video Capabilities: Moving Beyond Stills

Video recording has become a critical feature for many users.

• Olympus 550WP video tops out at 640x480 VGA at 30 fps, recorded in Motion JPEG - rather dated even in 2009.

• Panasonic GX85 delivers 4K UHD video (3840x2160) at 30/24 fps, along with 1080p up to 60 fps using modern codecs (MPEG-4 and AVCHD). It also supports 4K Photo mode, allowing you to grab an 8MP still from 4K footage - useful for sports or wildlife.

Both lack microphone and headphone jacks, which limits professional audio capture.
