• ZS100: Equipped with a 3-inch 1.04-million-dot fixed touchscreen coupled with a high-res 1.17-million-dot electronic viewfinder (EVF) that covers 100% frame at 0.46x magnification. The EVF and touchscreen enable more precise framing and quick setting adjustments, especially useful for macro and street photography.

Given these capabilities, the ZS100’s superior interface favors intuitive, modern workflows, particularly for beginners and on-the-go shooters.

Lens and Focal Range Flexibility

A decisive factor distinguishing these cameras is their lens systems.

• Olympus E-500: Utilizes a Micro Four Thirds mount, supporting a vast and mature lens ecosystem with over 45 compatible lenses (including primes, zooms, macros, and specialty optics). The 2.1x crop factor doubles effective focal length, providing extensive telephoto reach for wildlife or sports but limiting ultra-wide options.

• Panasonic ZS100: Comes with a fixed 10x zoom lens, equivalent to 25–250mm at F2.8-5.9. This wide-to-telephoto versatility is outstanding for a compact but lacks the optical quality and flexibility of interchangeable lenses, particularly in aperture speed and bokeh control.

If one prioritizes optical variety or low-light portraiture with fast primes, the E-500’s system lens compatibility is a major advantage. Conversely, the ZS100’s fixed zoom covers diverse scenes with no lens changes, ideal for travel convenience.
