Both cameras break the mold in their own ways and hail from distinct photography philosophies. I’ve spent dozens of hours putting them through their paces across genres, lighting conditions, and use cases to distill practical insights no spec sheet alone can offer.

Grab a coffee, and join me as we explore everything from sensor tech and autofocus wizardry to ergonomics and real-world image quality. By the end, you’ll have a clear sense of which camera suits your shooting style and ambitions - whether you're a budget-conscious enthusiast striving for stellar landscapes or a wildlife photographer craving reach and speed.

First Impressions: Handling and Ergonomics Show the Generation Gap

The initial tactile experience often sets the tone for long-term satisfaction. Olympus’s E-3 hails from an era where robust DSLR build quality and a thoughtful control layout were paramount, while the Panasonic FZ70 embodies a bridge camera’s convenience first approach.

When placing them side by side, you immediately notice that the E-3 offers a more substantial grip area and heft, weighing in at 890 grams versus the FZ70’s 606 grams. Physically, the E-3 measures 142x116x75mm, slightly larger but still comfortable in the hands of shooters coming from classic SLRs. The FZ70, at 130x97x118mm, is chunkier depth-wise, largely due to its extensive zoom lens barrel, yet remains relatively lightweight for its class.

Ergonomically, the E-3 sports an optical pentaprism viewfinder and a fully articulating 2.5-inch display, albeit with a modest 230k-dot resolution. The articulating screen is fantastic for challenging shooting angles - a boon for macro and street photography alike. In contrast, the FZ70 features a fixed 3-inch 460k-dot TFT LCD, brighter and sharper but locked in place. For those who frequently shoot off-axis, I found the E-3’s articulated screen far more versatile.

The control layouts diverge too. The E-3 offers a classic DSLR button and dial arrangement with customizable top and rear dials, allowing on-the-fly exposure tweaking which is indispensable during changing light situations.

The FZ70 leans towards simplicity. Its buttons and dials are fewer and larger, intended for casual shooters or travelers who want straightforward access without menu digging. The electronic viewfinder (EVF) on the Panasonic is adequate with a 202k-dot resolution - not stellar compared to modern EVFs today, but serviceable for composing in daylight.

From my years of fieldwork, I lean towards the E-3’s thoughtful manual controls and articulated display for professional flexibility, while the FZ70’s lighter weight and straightforward layout appeal when portability and ease are king.

Sensor and Image Quality: When Four Thirds Meets Superzoom Small Sensor

The two cameras stand worlds apart in sensor technology and image quality potential.

The Olympus E-3 houses a 10.1MP Four Thirds CMOS sensor measuring 17.3 x 13 mm, a format significantly larger than the FZ70’s tiny 1/2.3-inch (6.17 x 4.55 mm) sensor. Larger sensor real estate translates directly to better light gathering, dynamic range, and control over depth of field.

While the FZ70 compensates with a massively extended 20-1200mm equivalent zoom - a stupendous 60x range - its sensor constraints impose limitations. DXO Mark scores illustrate this divide clearly: the E-3 scores 56 overall, with superior color depth (21.6 bits) and respectable dynamic range (10.5 EV), compared to the FZ70’s 41 overall and lower color depth (19.4 bits) despite slightly better dynamic range (10.8 EV) under ideal conditions.

My empirical testing corroborated these figures. The E-3’s RAW files preserve highlight and shadow details remarkably well, a boon for landscape and portrait photographers who rely on post-processing latitude. Skin tones rendered beautifully smooth and nuanced, with less noise creeping in at higher ISO settings. The E-3’s native ISO tops out at 3200, beyond which noise becomes objectionable but still manageable. The FZ70 shares this maximum ISO but, due to its sensor size, noise becomes more apparent past ISO 800 in real-world use.

On the FZ70, fine detail, especially in low contrast areas or shadowed scenes, is less refined. However, its 16MP sensor delivers respectable resolution in ample daylight, and the camera’s onboard image stabilization helps mitigate blurring during handheld telephoto shots.

Autofocus Systems: Phase-Detection DSLRs vs Contrast-Detection Superzooms

Autofocus often makes or breaks the shooting experience, particularly in dynamic scenarios like wildlife, sports, or street photography.

The Olympus E-3 employs an 11-point phase-detection autofocus module, allowing fast and relatively accurate focusing even in challenging lighting. While it lacks some modern innovations such as eye detection and animal tracking, its phase detection system was cutting-edge in 2008 and still offers dependable performance. Continuous AF mode and selective focus points give the user control during action shots, although focus tracking is limited.

By comparison, the Panasonic FZ70 relies solely on contrast-detection autofocus with 23 focus points and includes face detection. Its AF can sometimes “hunt” in low light or at extreme telephoto lengths, an understandable compromise given the slower autofocus inherent in contrast-detection systems. However, it offers continuous autofocus tracking, which I found surprisingly effective for casual wildlife and street photography.

From my experience chasing birds at dawn or capturing runners mid-stride, the E-3 provides a higher confidence level in locking focus and tracking subjects. The FZ70’s impressive 9fps continuous burst rate is tempting, but autofocus lag occasionally wrecks critical frames.

Build Quality, Weather Sealing, and Reliability

The Olympus E-3 was one of the first DSLRs in its class to offer a robust magnesium alloy body with comprehensive weather sealing. My time shooting it in damp, windy conditions and light rain confirmed its resilience. The shutter and mirror mechanism feel solid, with an 8000 max shutter speed allowing for creative high-speed captures.

The Panasonic FZ70, being a bridge superzoom, is not weather sealed. The plastic construction keeps weight down but at the expense of ruggedness that outdoor photographers might prioritize. Some FZ70 users might find this acceptable given its target as an everyday travel camera or casual snapper.

Viewfinders and LCDs: Optical Versus Electronic - Which One Works?

The Olympus E-3 sports a 100% coverage optical pentaprism viewfinder with 0.58x magnification - bright and clear, delivering a natural real-time image with no lag or pixelation. This optical fidelity truly shines in bright conditions where LCDs can falter.

Meanwhile, the Panasonic FZ70’s electronic viewfinder features a lower resolution with 100% coverage. While helpful when shooting in harsh sunlight, the EVF’s lower refresh rate and resolution can be fatiguing for extended use.

On-screen, the FZ70’s 3-inch LCD panel is larger and notably sharper, which benefits live view composition and playback review. The E-3’s fully articulated 2.5-inch screen is somewhat small and lower resolution but offers a versatile viewing angle, critical for macro and candid shots.

Lens Ecosystem and Focal Range: Prime Considerations for Serious Photographers

One of the E-3’s standout advantages lies in its interchangeable lens system using the Four Thirds mount. At release, Olympus provided access to a robust lineup including 45 native lenses ranging from ultra-fast primes to pro-grade zooms, plus third-party options from Panasonic and Sigma. This multitude of glass permits specialization for portrait bokeh, macro precision, landscape sharpness, and wildlife telephotos.

In contrast, the Panasonic FZ70 comes with a fixed superzoom lens encompassing an incredible equivalent focal length range from 20 to 1200mm, a 60x optical zoom. Such reach is rare and well-suited for casual wildlife and travel photography without additional lens changes.

I’ve often taken the E-3 with its high-quality 50mm f/2 macro or 70-300mm telephoto for dedicated projects where image quality and lens performance were paramount. The FZ70’s one-lens solution offers unbeatable convenience but comes with compromises like slower variable aperture (f/2.8-5.9) and optical limitations at extreme zoom due to diffraction and softness.

Battery Life and Storage Considerations

Battery life is crucial for outdoor shooting. The FZ70 shines here with approximately 400 shots per charge, assisted by its smaller sensor and efficient Venus Engine processor. The E-3’s battery longevity specifics are less clear but generally, DSLRs with heavier use see fewer shots per charge, typically around 350-400.

Regarding memory, the E-3 supports both Compact Flash and xD Picture Cards, a flexible but now somewhat dated choice. The FZ70 uses SD/SDHC/SDXC cards, common today and generally faster for continuous shooting modes.

Connectivity and Video Capabilities

Neither camera offers wireless connectivity or Bluetooth, reflecting their release eras. USB 2.0 is their sole wired connection, limiting tethered shooting and quick file transfers by modern standards.

Video on the Olympus E-3 is nonexistent - there is no video recording function. It was primarily designed as a stills shooter for professionals and enthusiasts who favored image quality over video.

The Panasonic FZ70 includes Full HD 1080p video capture at 50/60i, with options for 720p and VGA as well. Though lacking microphone inputs and advanced codecs, it’s a functional video tool for casual home movies and travel diaries. Optical image stabilization further aids handheld video stability, enhancing overall footage quality.

Weighing Their Strengths Across Photographic Genres

Photography is diverse, so let’s parse each camera’s suitability by genre:

Portrait Photography

Olympus E-3: Larger sensor and lens interchangeability yield superior skin tone reproduction and bokeh control, especially with prime lenses. The articulating screen and manual focus aids are valuable for framing tight headshots. However, its lack of advanced eye detection AF is a limitation.

Panasonic FZ70: Adequate for environmental portraits but limited bokeh and background separation due to small sensor and lens aperture range. Face detection autofocus works well for casual snapshots.

Landscape Photography

The E-3’s Four Thirds sensor delivers better dynamic range and image detail critical in capturing the nuanced light of dawn or sunset scenes. Weather sealing supports fieldwork in rough conditions. Its RAW files are a pleasure to process for landscapes.

FZ70’s small sensor constrains image quality, especially in low contrast or shadow recovery, but wide 20mm equivalent offers decent framing flexibility for wide vistas. No weather sealing limits field use.

Wildlife Photography

The FZ70’s extraordinary 1200mm reach and 9fps burst are compelling for distant wildlife. Despite slower autofocus, it’s versatile for snap shots where super telephotos are needed.

The E-3’s DSLR phase-detection AF beats the FZ70 in subject tracking and autofocus agreement. But paired lenses with equivalent reach are bulkier and more expensive.

Sports Photography

E-3’s speedy 5fps and robust AF system provide better subject tracking and exposure control under fast action. Superior optical viewfinder means faster reaction times.

The FZ70 offers higher fps at 9 but its AF lag and slower shutter speeds cap performance for professional sports photography.

Street Photography

E-3’s articulating screen and crisp EV coverage allow discreet shooting in crowded scenes, augmented by low light capability and bokeh control for storytelling portraits.

FZ70’s bulky zoom barrel and lack of quick manual controls hinder quick candid shots. Smaller size and zoom flexibility somewhat balance this.

Macro Photography

E-3 with dedicated macro lenses excels, offering close focusing distances with excellent detail reproducibility.

FZ70’s 1cm macro close focus is impressive for a bridge camera, useful for casual flower or insect shooting, but image quality limitations of the small sensor manifest when cropping tightly.

Night / Astrophotography

Larger sensor and superior high ISO performance give E-3 an edge in noise control and image fidelity under low light.

FZ70 struggles beyond ISO 800 due to sensor noise, restricting night shoot possibilities.
