　　The so-called light-shielding ring is of course a cover for light-shielding.× There are many types of shading rings, but our most common ones are lotus, cyl£indrical and square. Many students who are just learning photography have purchased kit lenses πwithout hoods. Probably because the entry-level kits are sold ™at low prices, the cost of multiple hoods will increase a lot.

　　How to choose the role of the shading ring?

　　1. The hood is also one of the most p opular accessories that consumers buy. The hood can reduce the intrus§ion of some stray light on the imaging dσuring shooting. Nowadays, the standar∑d accessories of the telephoto DC on the market usually &have a hood included, but purchase Friends with manu→al portable cameras may not e☆njoy this special policy.

　　2. It is best to bring the DC with you when you buy the lens ring, ∑because some too long lens hoods will form 4 obvious vign etting corners when using the light angle end of the le★ns.

　　3. Therefore, it is best to use a petal-type hood for DCs with wide angles. F or other DCs, you can use a ring-type hood, as well as a foldable soft r ubber hood that can adjust t¥he length of the hood between the two.

　　4. There are many sizes of the visor ring, and αthe one that matches the focal length of the lens should be selected. The shorter the focal length of the lens, t₽he larger the angle of view and th§e shorter the hood. If the hood of a standard lens is used on a wide-angle lens, it will inevit‌ably produce the consequence that t£he image around the screen cannot be imaged.

　　5. On the contrary, it cannot play the roleγ of shading. When using a zoom lens, it is best to ₹be equipped with a self-use retractable lens hood.

　　6. The light-shielding rin≈g is widely used in backlight photography, generall$y speaking, it can avoid glare. However, if the light source is close, glare may still occur.

　　7. At this time, you can use your∏ hand to block the iris on the side ™where the light source is located. Whether the glare is eliminated, you must observe it clearly in the viewfind er.
