Function of lens hood of SLR camera Matters needing attention in purchasing hood

When we buy a SLR lens, we will find a hood on the SLR lens. The lens hood of SLR camera is made of metal hard plastic, soft rubber and other materials. Most SLR lenses are equipped with a hood, and some lenses need to be purchased separately. So what does the lens hood of SLR camera do? What are the precautions for using range hoods? Let me introduce it to you.

The function of the hood of SLR camera

1. When taking photos with backlight, sidelight and flash, it can prevent non-imaging light from entering and avoid fogging.

2. You can shoot under strong light and side light to avoid the surrounding astigmatism from entering the lens.

3. In light photography and night photography, it can prevent the nearby interference light from entering the lens.

4. It can effectively protect the lens, prevent accidental injury caused by lens falling, prevent fingers from touching the lens surface by mistake, and shield the lens from wind, sand, rain and snow.

Matters needing attention in purchasing the hood of SLR camera

1, the size of the hood is varied and should match the focal length of the lens. If you want to buy it, you must confirm the size before buying it or bring a camera directly to match it.

2. The shorter the lens focal length of a SLR camera, the larger the viewing angle and the shorter the hood. If the wide-angle lens uses a standard hood, it will lead to no imaging, otherwise there will be no shading effect, so the lens shading is best not to be interchanged. If a zoom lens is used,

It is best to match with a retractable hood. 3. The hood is widely used in backlight photography, which can avoid glare. However, if the Ruigu language is close to the light source, glare will still appear. At this time, you can use the side where the hand source is located to block the hood, which can reduce glare. Usually lenses are equipped with a hood, but different lenses have different hoods.

The lens baffles of most SLR cameras are not interchangeable. 4. The lens hood of SLR camera can reduce the glare effect of shooting external stray light, so it can be used on the lens which is located at the front end and does not rotate when focusing. Generally speaking, the longer the hood, the better the shading effect will be. However, if the hood of the bottle mouth is too long, it will block the four corners of the imaging pattern, and the petal-shaped hood will be recessed inward corresponding to the four corners of the picture, and will not block the light of the main four corners or the four corners.

Editor's summary: The above is an introduction about the function of lens hood of SLR camera and the matters needing attention in purchasing. I hope those SLR enthusiasts can help. The lens hood of SLR camera can effectively resist stray light and protect the lens, which is an essential accessory for SLR lens shooting.
