I’ve spent countless hours evaluating their sensor performance, autofocus responsiveness, ergonomics, and real-world output across portrait, landscape, wildlife, video, and more - revealing nuanced trade-offs and clear advantages on either side.

In this in-depth comparison, I will unpack everything you need to know to decide which camera aligns with your photographic ambitions and workflow, supported by my extensive field testing and technical analysis.

Size, Weight, and Handling: Ergonomics Matter for the Long Haul

Before diving into image quality and autofocus, first impressions of any camera come down to how it feels in your hands - an often underrated aspect that can influence shooting enjoyment and steadiness.

The Olympus E-3 is notably larger and heavier than the more compact Panasonic GX8.

The Olympus E-3 is a mid-sized DSLR body boasting robust construction and a heft of 890 grams. Its dimensions (142x116x75 mm) underscore its solid, classic SLR stance. Those accustomed to traditional DSLRs will appreciate the sizeable grip and physical heft that all but promise stability - especially for telephoto shots or longer events.

Contrast this with the Panasonic GX8’s rangy mirrorless build at roughly half the weight (487 grams) and a significantly slimmer profile (133x78x63 mm). It’s a noticeable ergonomic shift toward a more travel-friendly and inconspicuous form factor without sacrificing a firm handhold. The fully articulating 3” touchscreen adds modern convenience that photographers shooting from low angles or selfie-mode will find invaluable.

For photographers who prize raw shooting speed and tactile feedback - particularly in outdoors or professional contexts - the Olympus E-3 wins some points. But mirrorless enthusiasts and travelers will gravitate toward the GX8’s more modern ergonomic design and lighter package.

Sensor Performance & Image Quality: Two Eras of Micro Four Thirds

The heart of any camera is the sensor, and here we see the clearest generational leap. The Olympus E-3 houses a 10MP Four Thirds CMOS sensor, while the Panasonic GX8 sports a more contemporary 20MP Micro Four Thirds sensor. This difference in resolution - without changing the sensor area (both measure 17.3x13 mm) - has a direct impact on image detail and cropping flexibility.

Both share the same sensor size but drastically differ in resolution, dynamic range, and pixel count.

Lab testing from DxOMark confirms this real-world advantage:

• Olympus E-3: Scores 56 overall; color depth of 21.6 bits; dynamic range 10.5 EV; low-light ISO performance hits 571.
• Panasonic GX8: Scores a significantly higher 75 overall; color depth climbs to 23.5 bits; dynamic range 12.6 EV; low-light ISO 806.

What does all this mean practically? The Panasonic delivers richer skin tones, finer landscape textures, and superior shadow detail - invaluable for portrait and landscape photographers pushing the files in post-production.

While the Olympus E-3’s sensor has a more vintage character, its output still holds up well in controlled lighting, especially with carefully exposed JPEGs and Olympus’s TruePic III processing. However, I find its 10MP ceiling limiting when cropping or printing large. Conversely, the GX8’s 20MP sensor provides greater latitude and resolution without excessive noise at moderate ISOs.

The Olympus also incorporates sensor-based image stabilization, a notable feature in 2008, while the GX8 continues that tradition but refines it further with more advanced algorithms, benefiting handheld shooting dramatically.

Autofocus Systems: Speed, Precision, and Adaptability

Autofocus technology often makes or breaks shooting dynamic subjects, and here the cameras reveal their differing generations and system philosophies.

The Olympus E-3 relies on a phase-detection autofocus system with 11 focus points (cross-types unknown). It supports single and continuous AF but lacks advanced tracking, face detection, and live view autofocus capabilities.

The Panasonic GX8, meanwhile, includes a 49-point autofocus system heavily based on contrast detection, augmented by Depth From Defocus (DFD) technology. It supports continuous AF tracking, face detection, and touch-enabled focus, giving it a more modern, flexible autofocus suite.

The GX8’s touchscreen and electronic viewfinder afford enhanced AF interaction, noticeably smoother during video and live view magnification.

Through extensive field testing, I found the E-3 autofocus reliable and swift in steady light and decently responsive in low light, but it struggled with fast-moving subjects in continuous mode due to lack of sophisticated tracking. This makes portraits and landscapes its forte but sports or wildlife photographers looking to track erratic motion may be left wanting.

The GX8 shines with a burst frame rate of 12fps and continuous tracking autofocus (AF-C) that eagerly locks onto subjects, thanks to its computational algorithms. For street or wildlife shooting, this translates into a higher keeper rate and confidence in unpredictable situations.

Face and eye-detection AF on the GX8 also aids in portrait photography - something the E-3 can’t match organically.

Build Quality and Environmental Resilience

Professional users, especially those shooting landscapes, wildlife, or events outdoors, demand durability alongside performance.

The Olympus E-3 is famously rugged for its time, offering weather sealing - magnesium alloy body, resistant against dust and moderate rain - making it a trustworthy companion for variable conditions. It doesn’t claim full dustproof or freezeproof certifications but delivers peace of mind for fieldwork.

The Panasonic GX8 also offers splash and dust resistance, albeit with a more plasticky but well-engineered body. While not as bulky, its sealing meets modern mirrorless standards, which has proven reliable in light rain or dusty conditions, from my experience.

Neither camera is waterproof or shockproof, so additional protective gear remains advisable for extreme environments.
