Photography equipment has evolved dramatically since the dawn of digital imaging. Comparing cameras from different generations can be instructive, revealing how technology advances impact practical usability across diverse photographic genres. Today, I put under the microscope two Micro Four Thirds-format cameras separated by over a decade: the 2005 Olympus E-500 DSLR and the 2017 Panasonic Lumix DC-G9 mirrorless. Both share the Four Thirds sensor size and mount ecosystem but diverge sharply in technological sophistication, handling, and feature breadth.

Drawing on years of hands-on testing, I analyze these two cameras' design, image quality, autofocus, handling, and much more through the lens of real-world photography. Whether you’re an enthusiast eyeing budget gear or a professional weighing modern tools, this detailed comparison aims to impart the nuanced insights that help you pick the right fit for your creative needs.

First Impressions: Size, Ergonomics, and Design Philosophy

At first glance, the Olympus E-500 and Panasonic G9 reveal their lineage and target users through their builds.

The E-500, often referred to under its alternative EVOLT branding, hails from a mature era of DSLR design: a mid-size SLR with a traditional optical pentaprism viewfinder. Its dimensions - about 130x95x66 mm - and weight just shy of 480 grams place it as a relatively compact DSLR for its time. Handling is straightforward, with a fixed 2.5-inch LCD and simple control interfaces. Olympus crafted it as an "advanced DSLR," targeting enthusiasts upgrading from point-and-shoots into interchangeable-lens photography.

The Panasonic G9, however, wears the mantle of a professional-tier mirrorless camera released over a decade later. Sporting a heftier 658 grams and a somewhat larger footprint (137x97x92 mm), it balances robustness with ergonomics ideal for long shooting sessions. It features a fully articulated 3-inch touchscreen plus a high-resolution electronic viewfinder (EVF). Developed for demanding photographers shooting fast action, landscapes, and video, it boasts weather sealing and powerful image stabilization.

Let's nail down these physical contrasts visually:

The G9's solid grip and button placement cater to quick operation, while the E-500 reveals its era's restrained control layout. The E-500 feels lighter but less substantial - adequate for casual shoots, yet the G9’s bulk provides comfort for extended professional use.

Control Layout and Interface: Navigating Eras of Camera Ergonomics

Moving beyond physicality, how a camera allows the user to engage with settings and shooting functions can make or break efficiency in the field.

Here’s a top-down look:

On the Olympus E-500, the design is simple but dated - with no dedicated top LCD panel, mode dial, or illuminated buttons. The user cycles through settings mostly via rear buttons and a small color LCD, which lacks touchscreen capability. This setup encourages deliberate shooting but slows down changing parameters on the fly. It has no live view, locking you into optical viewfinder usage only.

The Panasonic G9, newest in the lineup, sports a sophisticated top LCD panel giving at-a-glance exposure, ISO, and white balance info. Its shutter speed dial, customizable buttons, and joystick empower advanced shooters to adjust rapidly without fiddling through menus. The fully articulating touchscreen supplies live view with touch focus, tap-to-shoot, and intuitive menu interactions. This circular shift toward immediate control suits sports and wildlife photographers who need split-second responsiveness.

Sensor Technology: From 8 to 20 Megapixels – Evolving Imaging Engines

Sensor performance remains the bedrock upon which image quality is built. Both cameras possess the Four Thirds sensor size (17.3x13 mm), facilitating compact lenses and effective depth-of-field control due to the 2.1x crop factor. Yet their sensor designs differ widely.

• Olympus E-500: Utilizes an 8-megapixel CCD sensor, typical for mid-2000s DSLRs. CCD sensors back then offered nice color rendition but lagged in noise handling and dynamic range. The native ISO range peaks at 400, with an extended maximum ISO of 1600, which is a stretch for clean images. The sensor includes an anti-aliasing filter, reducing moiré at a slight resolution cost.

• Panasonic G9: Boasts a modern 20-megapixel CMOS sensor, notable for its high-resolution output (5184x3888 pixels) and lack of anti-aliasing filter, enhancing fine detail reproduction. It has an impressive native ISO range from 200 up to 25,600, expandable down to ISO 100 for better exposure control. The CMOS sensor enables advanced readout speeds for silent shutter modes and video recording.

Through rigorous lab tests and field shooting, I observed that the G9's sensor delivers richer dynamic range, more faithful color depth, and superior high-ISO noise control. The E-500, though respectable for landscapes under daylight, simply can’t keep pace under dimmer conditions or with modern post-processing expectations.

Viewing Experience: Optical vs Electronic - The Viewfinder and Screen

The choice between optical and electronic viewfinders reflects the fundamental paradigm shift in camera technology.

• The E-500 has a 0.45x magnification optical pentaprism with 95% frame coverage. It's a classic DSLR viewing experience: natural, real-time, and battery-conserving. However, with only 95% coverage, you lose a little border area, and focus confirming has limited feedback due to the modest AF points.

• In contrast, the G9’s EVF is a dazzling 3,680k-dot AMOLED panel offering 100% coverage at 0.83x magnification. This delivers a bright, high-resolution live preview of your exposure, depth of field, and focus confirmation. It even supports focus peaking and zebra patterns for video users.

While some purists prefer optical finders for their tactile realism, the advanced EVF on the G9 introduces operational advantages - especially when composing in live view, shooting videos, or evaluating exposure before the shutter clicks.

Autofocus Performance: Speed, Coverage, and Tracking Abilities

Nothing tests autofocus like rapid bursts in wildly changing conditions. The E-500 and G9 represent two autofocus system generations.

• The Olympus E-500 relies on a 3-point phase-detection system without cross-type sensors, offering center-, single-, and multi-area modes but lacking face or eye detection. Continuous shooting clocks in at a modest 3 fps, limiting action capture.

• The Panasonic G9 features an advanced contrast-detection autofocus system with 225 selectable points and face/eye detection - even animal eye detection for some species is available via firmware updates, though not formally listed here. Its blazing 20 fps burst rate with continuous autofocus makes it a fierce performer for sports and wildlife.

In my testing, photographers shooting birds in flight or fast sports will find the G9's predictive tracking far more reliable. The E-500's AF struggled with moving subjects and low light, often needing manual intervention.
