Lens hoods are primarily designed to prevent unwanted stray light from entering by extending & shading the end of the lens, ensuring no problems with vignetting or motor functions. in addition, since the end of the lens is extended, you also get the added benefit of some extra protection from accidental impact. Lens hoods match the specific focal length of the lens it was designed for. Item Specifications:     Product Description: Canon EW-83F

Ex-Demo Tamron SP 15-30mm f 2.8 Di VC USD DSLR Lens (Canon Fit) Incorporating professional features such as VC (Vibration Compensation) optical image stabilization, a constant f 2.8 aperture throughout the zoom range, whisper quiet & fast USD (Ultrasonic silent drive) focusing as well as a water & dirt repellent Fluorine coating on the new XGM front element. This Ultra Wideangle 15-30mm zoom lens continues Tamron’s development of lenses for professional photographers & enthusiasts, adding an ultra-wide-angle solution to their line-up of pro-quality optics for pro DSLR users.

Features: superb Image quality & performance The optical construction of 18 elements in 13 groups, including for the first time an XGM (e Xpanded Glass Moulded Aspherical) element within the front group & several LD (Low Dispersion) glass elements, assures that this lens delivers outstanding image quality throughout the entire zoom range & from corner to corner. VC stabilization Tailored for Ultra Wide & Low light Recognising the need for an image stabilization solution for fast f 2.8 ultra-wide-angle lenses, Tamron have tuned their VC (Vibration Compensation) system specifically for the zoom range of this lens to give excellent performance even with low light & slow shutter speeds. BBAR & e BAND lens Coatings Tamron have paid particular attention to their BBAR Broad-Band Anti-Reflection) which has been refined further for this Ultra wide lens. Coupled with the e BAND coatings this results in crisper, crystal-clear images with ghosting & flare being efficiently eliminated. Water & Dirt repellent Fluorine coating The front element has a special Fluorine coating to repel water & dirt in order to keep it as clean as possible & make it easy to clean resulting in clearer sharper images even when in challenging environments. Smooth background “bokeh” The 9 blade curved aperture construction gives amazing smooth backgrounds within the out of focus areas of your image when using wider apertures due to its near circular form. USD (Ultrasonic Silent Drive) autofocus control Tack sharp images with fast autofocus response & almost silent operation give great USD autofocus control to the photographer, together with Tamron’s Full Time Manual focussing operation allowing adjustment to focus manually without having to exit the AF mode. Unique built in Lens hood design This unique lens hood provides effective shading of the front lens surface over the entire zoom range to minimize flare. It utilizes the unique characteristics of the optical system in which the front lens group recedes as you zoom in from 15 mm to 30 mm. A double-hood structure has been also incorporated into the lens design for additional strength.
