Sensor and Image Quality: Quantum Leap from Small CCD to Four Thirds CMOS

A critical dividing factor lies in the sensor technology, dramatically influencing image fidelity, dynamic range, and low-light performance.

• FX580’s Sensor: Employing a 1/2.3-inch CCD sensor measuring 6.08 × 4.56 mm with a total sensor area of roughly 27.72 mm², the FX580 offers a 12-megapixel resolution capped at 4000 × 3000 pixels. While respectable for a late-2000s compact, CCDs are generally known for decent color rendition but middling noise performance at elevated ISOs. Its max native ISO of 1600, extendable to 6400 digitally, is more a marketing feature than a low-light champion.

• GM5’s Sensor: The game-changer is the GM5’s Four Thirds CMOS sensor (17.3 × 13 mm) with 16 megapixels and an overall sensor area of 224.9 mm² - nearly eight times the FX580’s surface area, which translates directly to superior light-gathering capability and noise control. With a native ISO range from 200 to 25600, the GM5 flexes advanced image processing via the Venus Engine, resulting in notably broader dynamic range (measured at 11.7 EV versus the FX580’s untested but inherently limited range) and color depth (22.1-bit vs unknown on FX580).

Comparing sensor size and anticipated image quality outcomes

In practical testing, the GM5 consistently delivers cleaner shadow detail, richer gradations in highlights, and improved performance in high-contrast scenarios such as backlit landscapes or indoor portraiture with mixed lighting.

The FX580, meanwhile, excels mostly in bright daylight or well-lit settings and produces output typical of early compact cameras: tendency towards higher noise and less subtle tonal transitions under challenging conditions.

Display and Viewfinder Experience: Fixed LCD Versus Electronic Advantage

The rear interface significantly impacts the shooting experience and composition flexibility.

• FX580: Features a fixed, non-touch 3-inch LCD with a modest 230k-dot resolution - sufficient for framing but limited in responsiveness and detail when reviewing images or navigating menus. The absence of an EVF mandates relying solely on the rear screen, which can be challenging in bright sunlight or when requiring quick eye-level framing.

• GM5: Boasts a 3-inch fixed LCD panel with a sharp 921k-dot resolution that supports touch functionality - a welcome feature for intuitive focusing and menu navigation. Crucially, the GM5 incorporates a 1166-dot electronic viewfinder covering 100% of the frame with a 0.46 magnification, providing eye-level shooting precision, sharper composition, and stability in bright or dynamic environments.

Lens Ecosystem and Versatility: Fixed Power Zoom vs Micro Four Thirds Flexibility

Lens choice shapes photographic creativity profoundly.

• FX580: Comes equipped with a built-in 25–125 mm (equivalent focal length) zoom lens with an aperture range from f/2.8 to f/5.9. This 5× zoom covers wide-angle to moderate telephoto but is limited by maximum aperture variability and optical quality inherent to compact zoom optics. The closest macro focusing distance is 5 cm, supporting casual close-up shooting but without specialized macro capabilities.

• GM5: Supports the entire Micro Four Thirds lens mount ecosystem, boasting over 100 available lenses ranging from ultrawide primes and fast portraits to super-telephoto zooms ideal for wildlife and sports. The micro four thirds system’s 2.1x crop factor means focal lengths feel longer than full-frame but still manageable and versatile. The availability of dedicated macro lenses further broadens scope for specialized photography.

This extensibility makes the GM5 inherently more adaptable to diverse shooting scenarios, from landscape to action to detailed macro work, given the appropriate lens selection.

Autofocus Performance: Fixed Contrast-Detect Versus Advanced Hybrid Systems

Autofocus speed, accuracy, and modes affect action shooting and focusing reliability.

• FX580: Utilizes a contrast-detection system with 11 autofocus points but lacks face or eye detection enhancements beyond basic face recognition. The AF system is designed for static subjects, with a limited continuous shooting rate of 2 fps, making it ill-suited for fast action or wildlife.

• GM5: Employs a more advanced contrast-detection AF with 23 points alongside live view capabilities and facial detection. It offers continuous AF and tracking modes, supporting 5.8 fps burst shooting - a significant upgrade for sports, wildlife, or candid street photography. Though it lacks phase-detection pixels, tested real-world focusing speed is noticeably superior to the FX580, aided by its more powerful processor.
