[QUOTE="rocketman122, post: 355678, member: 14443"] [B][I]Fluorine coating on the front element, Tamron’s first [/I][/B] [B][I]Due to the large diameter and the prominent convex profile of the front element, it is not practical to deploy a protective filter. For the first time, a fluorine coating is applied to the front element, which repels water or any type of dirt, while making it easier to remove such smudge when contaminated.[/I][/B] Here is a short list of key specifications: [LIST] [*]Focal length range of 15-30mm, designed for full-frame sensors [*]Maximum aperture of f/2.8 throughout the focal length range, can be stopped down to f/22, 9 diaphragm blades [*]18 elements in 13 groups with fluorine coating, eBAND coating against reflections, and aspherical and low dispertion elements [*][I][B]No filter thread (bulbous front element, built-in hood)[/B][/I] [*]Optical image stabilization [*]USD for fast, silent and smooth AF operation [*]Can focus as close as 0.28m [*]Weighs in at approximately 1.1 kg (2.43 lb) [*]Measures approximately 98mm (3.86″) in diameter, 145mm (5.71″) in length [*]Will be available for Canon EF, Nikon F, Sony A mounts [/LIST] it wont allow to mount a standard filter. it has a bulbous front.
