The Tamron 28-75mm f/2.8 lens is a contemporary of a design produced by every other major lens manufacturer.
The zoom range would qualify it as a wide angle to short telephoto on a film body, but on a digital body with an APS-C size sensor,
the focal range is an equivalent 42-113mm ( 1.5x) or 45-120mm (1.6x). It's arguable whether this focal range has been supplanted by
a newer crop of so-called digital lenses, optimized for the smaller sensor size: however, the remaining asset for this category of lens is its constant f/2.8 aperture,
useful in low-light situations and portraiture where a thin depth of field is required.
As well, it's a traditional full-frame lens, usable on full-frame film and digital cameras.
