Olympus SP-600 UZ vs Panasonic GX85: A Hands-On Comparison for the Discerning Photographer

In the ever-evolving world of digital cameras, it's easy to get swept up in the latest and greatest. But sometimes, understanding the gulf between compact superzooms and advanced mirrorless systems can illuminate just how far technology has come - and what you might need depending on your shooting style. Today, I’ll pit the 2010 Olympus SP-600 UZ against the 2016 Panasonic Lumix GX85 in a detailed, no-nonsense, hands-on comparison. These two sit at opposite ends of the spectrum, yet each offers unique benefits worth exploring.

Is it a straightforward choice? Not so fast. While the SP-600 UZ is a budget-friendly compact superzoom, perfect for travel and casual shooting, the GX85 is a sophisticated mirrorless camera favored by enthusiasts who crave manual control and image quality. I’ve spent hundreds of hours testing cameras in studios, landscapes, wildlife reserves, and urban adventures - so let's dive deep.

Form, Function, and Handling: Size Matters – But How Much?

Right out of the gate, the disparity is clear in physical presence. The Olympus SP-600 UZ is the quintessential compact superzoom - small, chunky, and ready to slip into a jacket pocket. Its dimensions (110x90x91mm) and weight of 455g make it lightweight and approachable. The fixed lens zoom ranging from 28-420mm (35mm equivalent with 5.9x crop factor) lends it versatility without fussing over lenses.

The Panasonic GX85 is a different beast - a rangefinder-style mirrorless camera, about 122x71x44mm and 426g, slightly smaller but heavier than the Olympus when you factor in lens weight (which can vary, of course). Its Micro Four Thirds mount opens up a vast ecosystem of lenses. The magnesium alloy and polycarbonate build feel solid without bulk.

Ergonomics-wise, the GX85 is the clear winner for serious photographers. Its grip, control dials, and button layout are thoughtfully designed for extended use - no sweaty hand syndrome here. The Olympus’s compact design sacrifices some comfort for portability, and frankly, you’ll be neck-craning a bit at times to keep your hands steady during long zoom shots.

While the Olympus has a minimalist control scheme, favoring automatic modes and limited manual override, the GX85 gives you shutter priority, aperture priority, full manual, and customizable function buttons. The learning curve is steeper on the Panasonic, but rewarding for those who want their gear to be an extension of their creative intent.

Sensor Battle Royale: Tiny CCD vs. Four Thirds CMOS

The heart of any camera is the sensor, and here’s where these two diverge dramatically. Olympus’s 1/2.3" CCD sensor (6.08x4.56mm) with a resolution of 12 megapixels is what you’d expect from an early 2010 compact: tiny, budget-oriented, and modest in dynamic range. The sensor area is a mere 27.72mm².

Compare that to the GX85’s 16-megapixel Micro Four Thirds CMOS sensor measuring 17.3x13mm - over 8 times the sensor surface area at 224.9mm². Larger sensor real estate equates to better light gathering, lower noise, and richer color depth.

Testing these cameras side by side, the GX85 repeatedly outperforms the SP-600 UZ in image quality, particularly in low light and dynamic range. The Olympus can deliver decent results outdoors in bright conditions but struggles with noise and detail in shadows or high-contrast situations. The GX85’s advanced Venus Engine processor and no-antialiasing filter arrangement enhance sharpness and color fidelity.

I used standardized test charts and real-world scenes - a forest with dappled light, a cityscape at dusk - and the GX85’s images exhibited fuller tonal gradation, deeper blacks, and less chromatic noise at ISO 800 to 1600. The Olympus’s maximum ISO is 1600 but images quickly degrade beyond ISO 400.

The LCD and Viewfinder: Seeing is Believing

Peeping through the viewfinder or checking your exposure on a screen is a tactile part of photography. The Olympus has a fixed, 2.7-inch LCD with a mere 230k-dot resolution. It doesn’t flip or tilt and, importantly, there’s no electronic viewfinder (EVF) to speak of. This means composing in bright sunlight can be a real pain, relying on the LCD which can wash out easily.

The GX85 doubles down here - a 3-inch tilting touchscreen sporting an impressive 1.04 million dots, alongside a 2.76 million-dot EVF that covers 100% framing and gives you zero lag. The EVF is a game-changer if you’re serious about manual focus, precise composition, and shooting in bright light.

What’s more, the touchscreen on the GX85 supports focus point selection and menu navigation, a far cry from the Olympus’s button-only interface. If you’re the type to curate your shots on the fly, the GX85’s interface is a hundred times more engaging.

Autofocus – The Art of Catching the Moment

We all know a camera’s autofocus (AF) performance can make or break a shot - especially when snapping wildlife, sports, or the fleeting decisiveness of street photography.

Olympus’s SP-600 UZ employs a contrast-detection system with 143 focus points, which in theory sounds good, but in practice, it’s sluggish and prone to hunting, particularly in low contrast or dim light. It supports AF tracking, but without face or eye detection. For slow subjects or landscapes, it’s passable but don’t expect to capture fast wildlife or sports moments reliably.

Conversely, the Panasonic GX85 features 49 focus points with contrast detection and some clever DFD (Depth From Defocus) autofocus enhancements. While it lacks phase detection AF on the sensor (which is more common in newer models), this camera still nails autofocus consistently in daylight and decent lighting. Its continuous AF tracking works well for moderately fast subjects, and crucially, it offers face detection with focus peaking for manual focus precision.

Whether you’re snapping kids or critters, the GX85’s AF feels more responsive and adaptable. The Olympus, while usable, necessitates patience or switching to manual focus for tricky scenes.

Lens Ecosystem: Fixed Zoom vs. Micro Four Thirds Freedom

One of the main trade-offs with compact superzooms like the Olympus SP-600 UZ is the fixed lens - a 28-420mm (35mm equivalent) zoom with an aperture range of f/3.5-5.4. While versatile on paper, this lens is optically limited and less sharp at the extremes. By contrast, the GX85’s Micro Four Thirds mount opens the floodgates to over 100 native lenses ranging from fast primes to ultra-telephotos.

The versatility is tremendous - want a blazing-fast 42.5mm f/1.7 for portraits? It’s available. Need a compact pancake lens for street shooting? There’s options. Macro, wide angles, stabilised zooms? Covered. This adaptability means your GX85 can grow with your needs; the Olympus is confined to its built-in lens.

Burst and Shutter Speeds: Capturing the Action

Olympus offers a surprisingly zippy 10fps burst rate on the SP-600 UZ, with shutter speeds ranging from 1/2 to 1/2000 of a second. This seems promising for sports or wildlife, but AF lag undermines its usefulness. Its shutter range is somewhat narrow, lacking any electronic shutter modes and no aperture or shutter priority exposure options - a big limitation if you want controlled exposures.

The GX85 gives a slower 8fps continuous shooting speed (which in my experience feels smoother and more reliable) but features electronic shutter speeds up to 1/16,000 second allowing silent shooting and wide aperture use in bright lighting. Plus, the GX85 supports shutter priority, aperture priority, and full manual exposure modes - critical tools for professional or enthusiast work.

Image Stabilization: The Silent Saver

Here’s a point where the GX85 shines starkly against the Olympus: sensor-based 5-axis image stabilization on the Panasonic, compared to none on the Olympus. I’ve tested handheld shots at longer focal lengths and slower shutter speeds on the GX85 and consistently obtained sharp photos without wobble.

The Olympus SP-600 UZ, despite its long zoom, lacks optical or sensor-based stabilization, meaning you’re left to your own shaky hands or higher ISO settings to compensate. On a camera with a 420mm zoom equivalent, that’s a recipe for blurred shots - especially in lower light.

Video Capabilities: From HD to 4K and Beyond

For videographers, the GX85 offers 4K UHD recording at 30p and 24p, with slow-motion options down to 60fps at 1080p. This puts it well ahead of the Olympus SP-600 UZ, which maxes out at 720p HD video at 24fps, a resolution that's outdated today.

What's more, Panasonic's 4K photo mode allows extraction of 8-megapixel stills from video frames - a feature that can capture fleeting moments a traditional shutter might miss.

Neither offers microphone or headphone ports, so serious audio work requires external recorders. The Olympus’s video capabilities are strictly entry-level whereas the GX85 holds its own for vlogging, travel videos, and short films.

Battery and Storage: Keeping You Shooting

The GX85 has a respectable battery life of about 290 shots per charge, which aligns with typical mirrorless expectations (and is respectable given the EVF and stabilization demands). The Olympus specs do not list battery life officially, but anecdotal tests suggest approximately 300 shots per charge with its rechargeable lithium-ion pack.

Both cameras use SD/SDHC cards and have a single card slot, so no worries on storage compatibility or complexity.

Connectivity and Extras

The SP-600 UZ is barebones - no Wi-Fi, Bluetooth, GPS, or NFC. HDMI and USB 2.0 ports are present but basic. The GX85, despite also lacking Bluetooth or NFC, packs built-in Wi-Fi for easy image transfer and remote control via smartphone - increasingly essential in today’s connected shooting workflows.

Practical Photography Performance Across Genres

No single camera is all things to all people. Let’s break down how each fares for different genres.

Portraits

For portraits, skin tone rendition, bokeh quality, and focus accuracy on eyes are paramount. The Olympus’s fixed lens and small sensor limit shallow depth-of-field effects, resulting in flatter backgrounds. Conversely, the GX85 can leverage fast primes (like the Panasonic 42.5mm f/1.7) to produce creamy, attractive bokeh and excellent color rendition. Plus, its face detection autofocus makes it easier to nail sharp eyes.

Landscapes

Landscape photographers need dynamic range and resolution for fine detail and shadow recovery. Here, the GX85 excels with its larger sensor and 16MP resolution, offering cleaner files for stitching panoramas or printing large. Weather sealing isn’t available on either, so caution is advised outdoors. The Olympus’s smaller sensor and limited dynamic range are more of a handicap in this field.

Wildlife

Wildlife photography demands fast autofocus, telephoto reach, and burst rates. The Olympus’s 420mm equivalent lens looks tempting, but the lack of stabilization, slow AF, and limited exposure control hinder real-world usability. The GX85, paired with a dedicated 100-300mm lens, offers faster AF and better image quality but sacrifices some reach. For casual wildlife shooting, the Olympus might suffice, but serious shooters will gravitate to the GX85.

Sports

Sports photography focuses on rapid burst rates and reliable autofocus tracking in varied lighting. While the Olympus’s advertised 10fps burst spins heads, its practical performance is hampered by AF lag and exposure control issues. The GX85’s modest 8fps with accurate AF tracking and fast shutter speeds is more effective.

Street Photography

Street shooters prize discretion, responsiveness, and portability. The Olympus, with its compact size, is unobtrusive but limited in control and image quality. The GX85, though slightly larger, can pack a pancake lens and benefits from silent electronic shutter modes for candid shooting.

Macro

Olympus promises a 1cm macro focus capability, which is surprisingly close, but the fixed lens's optical quality is limited. The GX85 benefits from specialized macro lenses and touch-focus features, plus focus stacking options for incredibly detailed close-ups.

Night and Astro

The GX85’s larger sensor and high native ISO (max 25600) outperform the Olympus’s max 1600 ISO. Low-light noise control, longer shutter options, and manual exposure make the GX85 a preferred tool for astro and night photography. The Olympus, in contrast, can struggle outside well-lit environments.

Travel and Everyday Use

For travelers, compactness, battery life, and versatility matter. The Olympus is pocketable and low-maintenance, good for snapshots and zooming around a city or landscape, but image quality will be basic. The GX85 balances portability with advanced features and superior image quality, making it a better companion for serious enthusiasts.

Professional Use

For pro work, reliability, raw file support, custom exposure controls, and robust performance are critical. The GX85 supports raw capture, custom white balance, bracketing modes, and focus stacking - missing features on the Olympus. Its lens selection and manual controls also align with professional workflows.

Cost and Value: What’s Your Photography Budget?

Price-wise, the Olympus SP-600 UZ sits around $189 new (or less used), a budget option targeting casual shooters wanting simplicity and zoom versatility.

The Panasonic GX85 commands about $800 new, a mid-range mirrorless offering substantial image quality and creative flexibility. Lens costs are extra, but the varied ecosystem means you can start affordable and upgrade gradually.

Given the gulf in price and capabilities, the choice hinges on your priorities: casual snapshotting with zoom convenience or serious image quality and creative control.

Final Thoughts and Recommendations

The Olympus SP-600 UZ is a modest superzoom compact that delivers ease, zoom reach, and budget-friendly fun. If you want a no-fuss camera to travel light and grab snapshots without juggling lenses or settings, it’s a reasonable choice - especially if cost is your primary factor.

However, for photographers seeking image quality, manual control, and an expandable system, the Panasonic GX85 is clearly the smarter investment. Its larger sensor, advanced autofocus, sensor-based stabilization, 4K video, and extensive lens ecosystem put it light-years ahead.

In my extensive hands-on testing across genres, the GX85 excels for portraits, landscapes, street, macro, and even semi-pro wildlife and sports work. The Olympus feels dated and constrained but has its place as a casual everyday or travel camera for those who prioritize simplicity over sophistication.

Who should buy the Olympus SP-600 UZ?
