Petal/crown shape reduces flare and aberration of light.
GOOD QUALITY PRODUCT!
for 55mm screw fit ( not bayonet fitting, please check your lens)
Petal lens hood for all 55mm lens threads. When used it does not allow for a lens cap to be fitted, lens hood will need to be removed to fit lens cap. This lens hood screws into the front of your lens or filter as a very good alternative to an expensive original hood. It also has a clamp collar nut that only needs a slight pressure to tighten onto your lens so it it not easily lost.. Some edge shadowing may occur depending on your lens. Some Wide angle lenses may show excessive shadows and this hood is not recommended. Internal focus lenses only recommended also otherwise the petal hood would spin on focus. Fits these lenses and others with a 55mm thread or filter.
