The EF 28-90mm f/4-5.6 II is a lightweight, compact, standard zoom lens. It is among the lenses with the fastest AF speed in its class when used with the EOS 300V.


-Compact, lightweight standard zoom lens.
-Among the lenses with the fastest AF speed in its class.
-Aspherical element used to maintain high image quality throughout the zoom range.
-Optics use only lead-free glass.

This compact, standard zoom lens that realizes 90mm at the telephoto end is virtually the same size as the EF 28-80mm f/3.5-5.6 V USM

The EF 28-90mm f/4-5.6 II is designed as a standard zoom lens for the EOS 300V. It is among the lenses with the fastest AF speed in its class when used with this camera. To achieve this increased speed the EF 28-90mm f/4-5.6 II uses an AF drive pattern optimised for the EOS 300V and features a new AF algorithm. The exterior design of the lens matches that of the EOS 300V and other EOS models. High image quality is ensured throughout the focal length range by the use of an aspherical element in one of the lens groups. Only environmentally-friendly lead-free glass is used for the optics.

The way in which a camera lens is constructed.
Measure of how strongly the system converges or diverges light. For an optical system in air, it is the distance over which initially collimated rays are brought to a focus. A system with a shorter focal length has greater optical power than one with a long focal length; that is, it bends the rays more strongly, bringing them to a focus in a shorter distance.For an optical system in air, the effective focal length (f and f′) gives the distance from the front and rear principal planes (H and H′) to the corresponding focal points (F and F′).
