The concept for cameras with live preview largely derives from electronic TV cameras.Until 1995 most digital cameras did not have live preview, and it was more than ten years after this that the higher end digital single-lens reflex cameras (DSLR) adopted this feature, as it is fundamentally incompatible with the swinging-mirror single-lens reflex mechanism.

Unlike DSLRs, most digital cameras lack the option to change the lens. Instead, most compact digital cameras are manufactured with a zoom lens that covers the most commonly used fields of view. Having fixed lenses, they are limited to the focal lengths they are manufactured with, except for what is available from attachments.
Lower-end camera phones use only digital zoom and do not have optical zoom, while many higher-end phones have additional rear cameras, including fixed telephoto lenses that allow for the simulation of optical zoom. Full-sized cameras generally have an optical zoom lens, but some apply digital zoom automatically once the longest optical focal ...
A few have optical zoom, and several have a few cameras with different fields of view, combined with digital zoom as a hybrid zoom feature. For example, the Huawei P30 Pro uses a periscope 5x telephoto camera with up to 10x digital zoom, resulting in 50x hybrid zoom.
