1. There are many sizes of hoods, you should choos←e the one that matches✔ the focal length of the le₩ns. Be sure to confirm the size before buying or bring the camera directly ↔to match it!
2. It should also be noted that the shorter the focal length of the lens, the larger the viewing ang€le, and the shorter the hood. If the hood of a standard lens is used on a wide-angle lens, it will inevi'tably result in the result th♥at the image around the screen cannot be imaged. On the contrary, it cannot pl∏ay the role of the lens hood. When using a zoom lens, it is best to use a self-use retractable lenΩs hood.
3. Lens hoods are widely used in backlight photograp↓hy. Generally speaking, glare can be avoided. However, if the light so<urce is close, glare may stil™l occur. At this time, you can use your hand to block the hood o₹n the side of the light source to see if the glare is eliminated , Observe clearly from the viewfinder.
When using the hood, you shou≈ld take into account the fac¥tors that it works in coordination with the flash, because sometimes the former often♦ blocks part of the light of the flash.
4. The lens hood is used to reduce the ×glare interference caused by the stray l<ight from outside the shooting a&rea, so it can only be used on the lens whose front end does not rotate whe♦n focusing.
Generally speaking, the longer the hood, the better the effect of blockingπ stray light. However, if the flat lens hood is t♦oo long, it will block the four corners <of the screen. The position of the flower pe★tal cover corresponding to♦ the four corners of the screen is recessed inward, whi≤ch can "keep away" the light from the four corner☆s of the screen. The petals are equivalent to exte♥nding a section of the hood forward, which can p↕rovide a better shielding effect than the round-mouth hood.
