The Tamron macro lens has been carefully made with 16 elements in 14 groups. The optical construction of the lens is made in a rotation pattern. The diaphragm is a thin plate in the lens that opens and closes from time to time when you click a picture. This diaphragm in this Tamron mid-range zoom lens has 7 blades to give you optimal results. The Tamron SP AF 28-75mm F/2.8 XR Di LD Aspherical (IF) lens can be used both by amateurs and professionals.
Performance
The maximum viewing angle of the Tamron Super Performance series lens is 75° and the minimum viewing angle is 32°. The Tamron SP AF 28-75mm F/2.8 XR Di LD Aspherical (IF) lens is ideal for most of the Canon digital single lens reflex cameras. The Tamron macro lens uses XR glass which is a special type of glass with high index of refraction. This XR glass enables compact construction of the lens in terms of length and diameter.
Chromatic aberration is a form of optical noise which reduces the sharpness and the brilliance of an image. The unique Low Dispersion (LD) elements in the Tamron SP lens are made of special glass materials which possess an extremely low colour dispersion index. The LD elements also compensate for the chromatic aberrations, which is generally a problem with telephoto lenses.
The minimum focal length of the lens is 28 mm and the maximum focal length is 75 mm. The F-stop of the Tamron camera accessory is F/2.8. The Tamron SP series zoom lens has ASL which represents the range of aspherical lenses from Tamron. These lenses have a surface which deviates from the ball form. The aspherical lenses strongly improve the correction of spherical aberration and coma. These lenses are made by combining plastic on the glass surface of the element.
