See all popular Lens Hoods for Tamron lenses. Lens Hoods (or lens shades) prevent stray light and protect your lens against damage, spray, rain and condensation.

Here is a list of hoods for lenses of the manufacturer Tamron.

How To Get The Sharpest Photograph: Improve Your Pictures With This Quick Trick

The purpose of a lens hood is to prevent incident light from the side from being reflected by lenses or mount parts and thus reaching the image sensor or film or even the eyepiece. This stray light can lead to considerable impairment of the image, for example through optical overlaps in the form of light fringes in the shape of the lenses, i.e. usually circles or rings – the so-called lens flares. Furthermore, the image of the photographed or observed object becomes dull and low in contrast due to stray light.

Why is stray light a problem?

A short exposure in ambient light – sunlight for example – can produce a noticeable flare effect due to indirect illumination from the side (the “angle of incidence”) of the subject by the lens. This “lens flare” occurs because the ambient light (at the object) reflects off the lens or mount elements and thus makes the image from the lens or mirror look dark or hazy. It is much more difficult to photograph with this type of flare effect than with a “direct beam” (as when shooting through the lens at the image sensor). The “angle of incidence” refers to the angle at which light is coming from the camera sensor. With a lens flare, the most important angle is the diagonally opposite angle from the image sensor (i.e. from lens to lens).

What are lens hoods?

There are two types of lens hoods, a “hard” lens hood and a “soft” lens hood. The first type of lens hood covers the lens barrel from the front side with a hardened cover, also known as a “cold lens hood”. It is usually of a two-piece construction. This type of lens hoods, if fitted properly, can reduce the intensity of stray light. On the other hand, if the lens hood is not fitted properly, then stray light transmission through it can be increased, and this can decrease image quality. The second type of lens hood is a “soft lens hood”, which is often covered by a third, more flexible and softer material, with an integrated attachment ring. The soft lens hood, on the other hand, can reduce the intensity of stray light.

When should I use a lens hood?

If you shoot with telephoto lenses, for example when photographing people or birds, the case is slightly different. With these lenses, light is scattered during the zooming so as to put the rays of light from the front of the subject onto the image sensor or film. In contrast, these same rays of light do not scatter when the lens is aimed straight ahead. This means that stray light from the front of the subject cannot be reflected in the image, thus reducing the amount of incident light from the front of the subject on the image sensor or film. Consequently, the pattern of stray light from the front of the subject is seen through the aperture blades of the lens and the resulting photographic image is more sharp. How often should I use a lens hood?

How do I use a lens hood?

Always place your lens hood where it will be needed when you take your picture. That way it will cover any part of the lens that might be visible in the photograph. If your hood is completely fitted around the lens, you can get away with only a slight gap at the nose of the hood itself, which you can cover with your hand or a small object. If not, you can use a little cleaning cloth or something similar to cover that gap to ensure that the lens hood does not disturb the image in any way. Properly placed lens hoods make your pictures look clearer, with less vignetting and fringing and depth of field Which lens hoods are best?
