with an optical zoom ratio of 2.5× (e.g. 28-70mm) to 5× (e.g. 24-120mm) — the most common being 3× (e.g. 24-70mm). They are called standard zoom lenses, because the midpoint of their zoom range is around 50mm, which is considered a standard or " normal" field of view.

History

High-quality optical formulas for wider-angle lenses are more difficult and expensive to achieve and produce, so older standard zoom lenses often started at 27mm or 28mm instead of 24mm at the wide end, especially for smaller sensor formats.

Variants

20-50mm

The increasingly popular 20-50mm zoom range is arguably more versatile than the more established 16-35mm lenses and shares the minimum 2.5× optical zoom ratio of 28-70mm lenses but shifted to a wider field of view. Even some new fixed-lens cameras like the Sony ZV-1 II are switching from a standard zoom lens to a wider zoom lens that covers this range.

35-150mm

The 35-150mm zoom range shares the 4× optical zoom ratio of 24-105mm lenses but shifted to a tighter field of view, which can be more useful for portraits.
