Olympus E-330 vs Panasonic GX85: Decoding Two Generations of Four Thirds Cameras

Over my 15+ years in professional camera testing, few comparisons have illustrated the rapid evolution of camera technology quite like a face-off between the Olympus E-330 and the Panasonic Lumix GX85. Separated by a decade, these two Micro Four Thirds-format cameras capture the transition from early DSLRs with live view to sophisticated mirrorless machines brimming with computational photography enhancements.

In this detailed review, I’ll take you through everything I’ve learned by putting these cameras side by side in studio tests and out in the field - covering portraiture, landscapes, wildlife, and more. Along the way, I’ll highlight each model’s strengths and weaknesses, draw on my hands-on experience with sensor tech, autofocus, build, and lenses, and ultimately help you decide which camera, if any, holds relevance in today’s photographic landscape.

Let’s dive in.

First Impressions: Size, Handling, and Ergonomics

The Olympus E-330 debuted in 2006 as an advanced DSLR with a mid-sized SLR body and a pioneering live-view system. In contrast, the Panasonic GX85 from 2016 offers an ultra-compact rangefinder-style mirrorless design with a robust feature set aimed at enthusiasts and professionals alike.

Looking at the physical measurements, the E-330 is noticeably thicker and heavier at 140x87x72mm and 616g, compared to the GX85’s svelte 122x71x44mm and 426g. My hands appreciated the Olympus’s deeper grip and sturdier heft, which can benefit stability during longer shoots - especially with larger lenses. However, the GX85’s compactness made it downright pocketable for travel and street photography, slipping easily under a jacket sleeve with a pancake zoom lens attached.

Handling beyond size is about button layout and menu navigation. The E-330’s optical pentamirror viewfinder and classic DSLR button arrangement feel old-school but remain functional. The GX85’s modern rangefinder aesthetics offer a streamlined control layout with tilting touchscreens and an advanced electronic viewfinder for live exposure previews. The GX85’s touchscreen responsiveness was a revelation compared to the E-330’s fixed, low-res display.

While the E-330 has fewer autofocus points and more basic exposure settings, it compensates with direct access dials and a forgiving interface. The GX85’s more numerous functions and customizable buttons allow faster adaptation to different shooting modes, especially important when moving from stills to video.

Sensor and Image Quality: The Heart of the Matter

Both cameras employ Four Thirds sized sensors measuring 17.3 x 13mm, but the GX85 boasts a substantial leap in resolution and sensor design.

The E-330 sticks with a 7 MP CMOS sensor featuring an anti-alias filter to reduce moiré, but at the cost of some image sharpness and detail. The GX85 sports a 16 MP CMOS sensor without an optical low-pass filter, which extracts noticeably sharper images with greater micro-contrast. In practical shooting, my tests revealed:

• Dynamic range: The GX85’s newer sensor with the Venus Engine processor delivers significantly increased latitude in shadows and highlights, allowing more latitude to recover under or overexposed areas without introducing noise or banding.

• ISO performance: The E-330’s native ISO maxes out at 400 with a boosted 1600, but noise is a limiting factor past 400. The GX85 comfortably shoots to ISO 25600, with clean results through ISO 1600 and usable detail well beyond that - even in challenging dimly lit interiors or evening landscapes.

• Color depth and accuracy: The GX85 scored 22.9 bits color depth on DxOmark’s scale, an impressive metric translating to richer gradients and smoother skin tones in portraits versus the untested but noticeably older sensor in the E-330.

For practical photographers, this means the GX85 provides sharper, cleaner images across scenarios, elevating your post-processing flexibility and print quality.

Display and Viewfinder: Peering Through the Eyes of the Camera

Live view technology was cutting-edge when Olympus introduced it on the E-330, but it’s rudimentary compared to the GX85’s advanced screen and EVF.

The E-330 features a 2.5-inch tilting LCD with a very modest 215k-dot resolution. It’s useful for composing awkward angles but lacks crispness, making detailed manual focusing or exposure verification tricky in bright daylight. The optical pentamirror viewfinder covers 95% of the frame with 0.47x magnification and no electronic overlays - familiar but basic.

By contrast, the GX85’s 3.0-inch tilting touchscreen provides a sharp 1,040k-dot resolution with touch focus and intuitive menu navigation. Its hybrid 2.76M-dot electronic viewfinder offers 100% coverage and detailed exposure aids like histograms and focus peaking, critical for manual work and video recording.

The upshot: for precise focusing, exposure control, and shooting in varied lighting, the GX85’s displays outperform the E-330 drastically, making the whole capture experience smoother.

Autofocus and Speed: Chasing the Moment

Autofocus technology is where the cameras reveal a gulf born of ten years and vastly improved processing.

The E-330 uses a phase-detection system with just three focus points - far from modern standards. Autofocus speed is slow by today’s expectations, with occasional hunting outdoors, especially in low contrast scenes. There’s no face detection or continuous tracking. Shooting action or wildlife with confidence requires manual focus or a lot of patience.

In contrast, the GX85 features a contrast-detection AF system with 49 focus points and face detection, including eye detection, making portraits far more reliable. Continuous autofocus tracking works well even at the 8fps burst speed, allowing me to capture athletes in motion or wildlife with better accuracy.

Panasonic’s inclusion of focus bracketing, stacking, and post-focus functions in the GX85 enhances creativity for macro photographers, where precision is paramount.

Build Quality and Environmental Sealing: Ruggedness Tested

Both bodies lack professional-grade weather sealing, so I wouldn’t recommend either camera for heavy rain, snow, or dusty environments without added protection.

However, the GX85’s compact design uses modern lightweight materials, reducing fatigue during all-day shoots, whereas the E-330’s larger bulkiness conveys a solid, classic build but can tire the wrist over time.

Neither camera is shock or freeze-proof, so for extreme adventure photography, an additional protective case or more robust system is advisable.

Lens Ecosystem: Micro Four Thirds Options Explored

Both cameras use Micro Four Thirds mounts, but availability and lens quality vary tremendously.

• The E-330 lists 45 compatible lenses - mainly Olympus Zuiko legacy optics designed originally for Four Thirds DSLRs. These lenses tend to be bulky and optically respectable but dated compared to newer designs.

• The GX85 enjoys access to over 100 native Micro Four Thirds lenses today from Panasonic, Olympus, Sigma, and others. This wide variety includes affordable primes, compact zooms, and cutting-edge stabilised optics to suit any style from macro to telephoto wildlife.

Thanks to the GX85’s sensor-shift image stabilization system, even older lenses get a performance boost, improving handheld sharpness.

Battery and Storage: Powering Your Shoots

The Olympus E-330’s specifications do not list definitive battery life figures, but my long-term use suggested short to moderate longevity, typical of DSLRs of the era. It uses Compact Flash (Type I/II) or xD Picture Cards - formats that are increasingly uncommon, potentially complicating media logistics today.

The GX85 features a rated 290-shot battery life, respectable for mirrorless cameras, and uses the ubiquitous SD/SDHC/SDXC cards, affording modern high-speed UHS-I/UHS-II support. Its USB 2.0 interface also enables tethered shooting and basic charging solutions with third party accessories.

Connectivity and Video Features: Meeting Modern Demand

Connectivity is a weak point for the Olympus E-330, offering only sluggish USB 1.0 transfer and no wireless features. Video capture is nonexistent.

By contrast, the GX85 embraces modern demands for hybrid shooters:

• 4K UHD video recording at 30p and 24p
• High frame rate Full HD capture and slow-motion possibilities
• 4K Photo mode for extracting high-res stills from video frames
• Onboard Wi-Fi for remote control and image transfer
• HDMI output for external monitors and recorders

This versatility makes the GX85 a true all-in-one tool suitable for vloggers and multimedia professionals, elevating it well beyond the E-330’s legacy stills-only platform.
