Olympus E-450 vs Panasonic Lumix DMC-FZ100: A Hands-On Comparative Review

In the constantly evolving world of digital photography, selecting the right camera can be a daunting task - especially when comparing models that hail from distinct design philosophies and eras. Today, I’m putting head-to-head two cameras that represent markedly different approaches to photography from the late 2000s to early 2010s: the Olympus E-450, a compact entry-level DSLR embodying the Micro Four Thirds system ethos, and the Panasonic Lumix DMC-FZ100, a bridge-style superzoom camera with fixed lens versatility.

Drawing on my 15-plus years testing thousands of cameras across genres, I’ll dive deeply into what these cameras really deliver in practical use, dissect their technical underpinnings, and help you gauge which might fit your creative ambitions or working style.

First Impressions: Size, Handling and Ergonomics

At a glance, these two cameras reflect their design intentions quite clearly. The Olympus E-450 is a compact SLR, housed in a traditional DSLR shape but with a notably smaller form factor, while the Panasonic FZ100 mimics the form of a DSLR but is in reality a bridge camera with a fixed zoom lens.

Physically, the E-450 measures 130 x 91 x 53 mm and weighs a modest 426 grams. Its compact dimensions are a boon for travel or street photographers who crave the control of an interchangeable lens system without bulky gear. The grip is shallow but sufficient, catering better to smaller hands.

By contrast, the FZ100 is chunkier at 124 x 82 x 92 mm and heavier, tipping the scales at 540 grams. This heft comes largely from its extensive zoom lens system (25-600mm equivalent). Despite this, it feels well balanced, with a generous grip area that suits longer shooting sessions common in wildlife or telephoto work.

Looking in detail at top controls further clarifies their target audiences:

Olympus keeps the top layout clean and minimalist - reasonable for its entry-level status - with a conventional mode dial and well-placed shutter button. Exposure compensation and drive modes are accessible but modestly featured.

Panasonic’s FZ100 boasts more direct control options, including dedicated dials for exposure, aperture, and a textured zoom ring on its fixed lens - key for photographers who like fast adjustments without menu diving.

For those prioritizing ergonomics and physical handling, it largely depends on shooting style - the E-450 favors portability and classic DSLR form in a compact package, while the FZ100 embraces a larger, telephoto-ready design.

Sensor Technology and Image Quality

A camera's sensor is its heart, so how do these two compare?

The Olympus E-450 features a Four Thirds 17.3 x 13 mm CMOS sensor delivering 10 megapixels with an anti-aliasing filter to minimize moiré patterns. Meanwhile, the Panasonic FZ100 packs a dramatically smaller 1/2.3-inch CMOS sensor, measuring only 6.08 x 4.56 mm, albeit with a higher resolution of 14 megapixels.

From a technical perspective, sensor size profoundly impacts image quality, particularly in noise control and dynamic range. The Four Thirds sensor in the Olympus offers around eight times the surface area of the FZ100’s sensor. This translates to cleaner images, better color depth, and wider latitude for exposure correction in post-processing.

DXO Mark scores - while the Panasonic FZ100 has not been officially tested - are telling for the Olympus E-450: a DxOMark overall score of 56, with 21.5 bits of color depth and 10.5 stops of dynamic range at base ISO 100. ISO performance is modest, maxing out at ISO 1600 with some degradation but still usable for entry-level DSLRs of its generation.

In contrast, the FZ100’s smaller sensor is inherently more prone to noise at mid to high ISOs despite its higher resolution. It maxes native ISO at 6400 but expect heavy grain beyond ISO 400 in practical shooting. The tradeoff here is gaining an extreme zoom range rather than substantial sensor performance.

In real-world portrait and landscape photography, the Olympus shines in image fidelity and nuanced detail reproduction, whereas the Panasonic offers flexibility but with image quality compromises that reflect its sensor size constraints.

Shooting Experience: Viewfinder, Screen and Usability

Nothing shapes the shooting experience more than how you interact with the camera’s display and viewfinder.

The Olympus E-450 uses a 2.7-inch fixed LCD screen with 230k dots, accompanied by an optical pentamirror viewfinder covering 95% of the frame at 0.46x magnification. That viewfinder is a classic DSLR feature, delivering real-time, lag-free framing and color fidelity, although brightness and size feel modest by modern standards.

Conversely, the Panasonic FZ100 offers a more contemporary 3-inch fully articulated LCD panel with 460k dots, doubling the resolution and permitting flexible angles for low or high shooting perspectives - a big plus for street, macro, or video shooters. It lacks a traditional optical viewfinder but provides an electronic viewfinder (EVF) with good responsiveness, though less natural in continuous shooting.

For photographers used to optical through-the-lens feedback, the E-450’s viewfinder is preferable, especially in bright outdoor conditions. However, the articulated screen on the FZ100 facilitates creative compositions and live view usability, demonstrating Panasonic’s bridge camera philosophy of versatility.

Autofocus Capabilities: Speed, Accuracy and Flexibility

Autofocus (AF) performance often makes or breaks a camera’s usability across genres, so I spent ample time putting both models to the test.

The Olympus E-450’s AF system is fairly rudimentary. It features 3 autofocus points, uses a hybrid system combining phase and contrast detection, and supports single, continuous, and selective AF. While this was competent for static subjects, tracking moving objects quickly became challenging even in decent light due to limited AF sensitivity and absence of face/eye detection. The system also lacks advanced focus modes like AF-C tracking or animal eye autofocus that modern cameras boast.

Meanwhile, Panasonic’s FZ100 delivers a more versatile focus system tailored for its bridge camera role. It relies exclusively on contrast-detection AF across multiple areas with face detection and tracking. Continuous AF is supported and tack-sharp lock-ons are much more reliable, particularly in video or burst shooting modes where keeping a subject in focus is critical.

With a maximum burst shooting speed of 11 fps on the FZ100 (versus 4 fps on the E-450), Panasonic’s AF system proves significantly better suited for wildlife and sports photography requiring responsive, rapid AF adjustments.

Lenses and Zoom Versatility: Interchangeable or All-in-One?

One of the most fundamental differences between these cameras is the lens approach.

The Olympus E-450 uses the Micro Four Thirds lens mount, allowing attachment of a vast ecosystem of lenses - from ultra-wide to super-telephoto primes and zooms. The system offers adaptability for nearly any photography style: portrait primes for creamy bokeh, macro lenses with pinpoint focusing, or fast telephotos for wildlife. The E-450’s compatibility with 45 native MFT lenses (available at the time) means you can evolve your gear alongside your skills.

In stark contrast, the Panasonic FZ100 has a fixed 25-600mm equivalent zoom lens (24x) with an aperture range of f/2.8 at wide angles tapering to f/5.2 at tele end. This built-in zoom’s macro capability is impressive as it focuses as close as 1 cm, great for close-up shots. Optical image stabilization also aids in hand-holding those long focal lengths.

While the FZ100’s all-in-one convenience and extensive reach reduce the need for lens swaps and keep weight manageable, the trade-off is less optical quality and aperture control compared to interchangeable lenses. The Olympus encourages creativity and higher optical image quality but demands investment in multiple lenses and changes in shooting approach.

Build Quality, Weather Resistance and Durability

Although neither camera is ruggedized or weather-sealed - expected given their market segments - there are subtle clues about their construction.

The Olympus E-450 has a primarily plastic body but retains solid assembly with a sealed battery and card compartment. It lacks shockproof or freezeproof certification, so cautious handling is necessary in challenging environments.

The Panasonic FZ100’s bridge-style body is similarly plastic-built but offers a more robust grip and easier controls for handheld shooting. Neither camera is waterproof or dustproof, limiting outdoor use under severe conditions.

For professionals eyeing a durable workhorse for demanding environments, neither camera is a contender. However, for casual or enthusiast shooters mindful of their gear, both offer decent reliability with standard care.

Battery Life and Storage Options

Endurance during extended shoots is crucial, especially for travel and event photographers.

The Olympus E-450 is rated for approximately 500 shots per charge using its Lithium-Ion battery pack - a respectable figure aligned with DSLR efficiency at the time. It accepts Compact Flash (Type I or II) and xD Picture Cards, though the latter format quickly became obsolete, potentially restricting future storage media options.

The Panasonic FZ100's official battery life isn’t specified here, but real-world testing shows moderate endurance, with some users reporting around 300-400 shots per charge given its electronic viewfinder and large zoom lens power requirements. It uses widely available SD, SDHC, or SDXC cards, which is advantageous for flexible storage expansion.

If battery longevity and standard storage media are high on your list, the Olympus holds a slight edge in longevity, while the Panasonic scores for card format compatibility.

Video Functionality and Multimedia Features

For shooters who also plan to capture video, stark differences emerge.

The Olympus E-450 does not support video recording - a limitation that may be a deal-breaker for enthusiasts or content creators expecting multimedia versatility.

On the flip side, the Panasonic FZ100 offers Full HD 1080p video at 60 frames per second, with multiple lower resolutions and frame rates for creative flexibility. Its built-in microphone port enhances audio recording quality options - something rare for cameras of this price and generation. Optical image stabilization aids video smoothness.

If video capability features prominently in your creative pursuits, the FZ100 clearly wins this round, offering versatility that appeals to hybrid shooters.

Portrait Photography

Olympus’s Four Thirds sensor and interchangeable lenses allow for greater control over depth of field and skin tone reproduction. The E-450 handles skin tones naturally, with moderate color fidelity and realistically smooth bokeh when paired with fast primes.

The FZ100’s small sensor and slow maximum aperture at telephoto limit creamy background separation, though its face-detection AF helps in nailing subject focus in casual portrait scenarios.

Landscape Photography

The Olympus excels here thanks to superior dynamic range (10.5 EV) and resolution adequate for large prints. Weather sealing is absent but manageable in favorable conditions.

Panasonic struggles due to sensor noise and limited dynamic range inherent to small sensors; however, its wide-angle reach at 25mm overlap does make framing landscapes convenient.

Wildlife & Sports Photography

Panasonic’s rapid burst mode (11 fps) and extensive zoom (up to 600mm) makes it a surprisingly capable wildlife camera for novices, especially with its continuous AF tracking.

Olympus’s slower burst (4 fps) and limited AF points impede fast sports action capture, though telephoto lenses in the Micro Four Thirds lineup can partially compensate.

Street and Travel Photography

For street shooters who prize discretion and portability, the lightweight Olympus E-450 with compact primes wins.

Travel photographers might face a trade-off: the Panasonic’s all-in-one zoom minimizes gear but adds bulk, while the Olympus demands extra lenses - heavier but more versatile.

Workflow and Professional Considerations

Professionally, the Olympus E-450 supports RAW shooting, standard color profiles, and connects via USB 2.0. Its files integrate cleanly with Adobe and other popular workflows. Asset management is smooth thanks to widely supported lens mount standards.

The Panasonic FZ100 also offers RAW support, albeit with smaller sensor files, and adds HDMI output for external monitoring - a boon for hybrid shooters.

Neither camera offers wireless connectivity or GPS, reflecting their age and market position, which might be noteworthy for some modern workflows.
