Digital vs. optical zoom: Understanding image quality

Smartphone photography often relies on digital zoom, which uses interpolation to stretch existing pixels to fill a frame. This process can result in soft, smeared, or blocky images when viewed on larger screens or printed, as the software must guess missing details. Unlike optical zoom, where lenses physically move to magnify a scene, digital zoom is essentially a crop that can degrade image quality.

In contrast, dedicated compact cameras like the Kodak PIXPRO FZ55 utilize true optical zoom. Currently available for $139.99 on Amazon, the FZ55 features a 16MP sensor and a 5x optical zoom. While it lacks the computational power of modern smartphones, it provides a tactile alternative for users seeking a simpler photography experience without the distractions of a mobile device.
