5 Reasons for using a Lens Hood

1Stronger contrasts: The lens is screened from stray light from the sides by the lens hood, which means no more lifeless, low contrast images.  

2Less lens flare: Stray light often leads to lens flares. These are bright, round or polygonal spots which stretch across the image.

3Protects the lens from damage: Just as the fender protects cars the lens hood protects the lens from falls or blows. 

4Protection against the weather: Depending on the design of the hood, the formation of droplets on the lens due to spray, rain or condensation is prevented.

5Styling: I admit it – it was in an important factor in my buying decision. My Olympus 14-42mm 1: 3.5-5.6 lens (pictured above) looks a bit naked without a lens hood.

Effect of a lens hood



PHOTOGRAPHED WITH HOOD: Stronger contrasts






4 different shapes of lens hood (synonym: lens shade, hood)

Tulip-shaped lens hood (=flower, petal or tulip shape)

This design is used in wide-angle lenses. Although lenses are circular, the image format or the chip is a rectangle in landscape. The lens hood is fitted on the lens so that the large leaves screen the stray light from above and below. The leaves on the right and left are shorter, so that the hood does not cause a vignetting of the image. Which means the image to the right and left will not be darkened.

Circular form (= cylindrical, conical, round, tubular, or barrel shaped)

This lens hood does not need a crazy design, since it is fitted to telephoto lenses. When using a round lens hood that is compatible with the telephoto lens, there is no risk that there will be any image vignetting. This design covers cylindrical to conical.

Square shape (rectangular shape)

On the other hand rectangular lens hoods are for wide-angle lenses. They fit perfectly to the detail of the photograph.

Ventilated design (vented lens hood)

The name is misleading. The recesses of course are not used for ventilation of the lens. These products are again something for wide-angle lenses. I only know of three reasons for this design:

  • Material savings (and weight saving too for lens hoods made of metal).
  • The viewfinder of some cameras is not obscured by this design (e.g. Leica M 50/2 Summicron).
  • They look cool and retro.

There are also, according to comments, retractable (extractable) lens hoods, which can contract and extend (bellows lens hoods). But I have never seen any.

It is the abbreviation for lens hood. There are various names for the lens attachment. For example, it is called a sun shade or lens shade.

If the wrong lens hood is used, a vignetting effect may occur.

It is stronger when a small focal length = wide image angle has been selected. The image on the left was shot with a wide-angle lens with an unsuitable universal lens hood that was too narrow. The shading is typically more pronounced left and right than up and down.

3 connection types for lens hoods

1Bayonet connection:  The lens hood is fitted with a quarter turn of the lens bayonet thread.

Lens hood with bayonet thread

Bayonet thread on the lens


This is the standard connection type for lens hoods. Lens hoods supplied by the manufacturer or as original accessories almost always have a bayonet fitting. However, the lens manufacturers have different bayonet thread standards (e.g. Canon EF, EF-S and EF-M bayonets, Olympus Four Thirds or Micro Four Thirds bayonet, Samsung has Pentax K or NX bayonets, etc.). On this page I have compiled a list of the lens bayonet connections. Hoods with bayonet connection can also be fitted backwards to the lens.

Therefore, with bayonet lens hoods, attention should be paid to the type of bayonet connection and the (technical) compatibility with the lens.

2Screw-in connection:  The lens hood is screwed onto the filter thread of the lens.





The filter thread of the lens is firstly mated with it. If you love to use filters in photography, you should make sure it has a (negative) filter thread on the front when buying a lens hood with a screw-in connection. This is the case for only 50% of screw-in lens hoods. Snap-on lens covers also need a filter thread, with which they can mate.

With screw-in connecting lens hoods, attention should be paid to the filter diameter (usually marked on the lens e.g. 58mm diameter) and compatibility with the lens.

3Slip-on connection and snap-on connection: For both types of connection the lens hood is attached to the lens. It does not have a thread.

Slip-on lens hood


Lens hood with snap-on connection


A clip or screw provides added support with a snap-on connection (right). Slip-on lens hoods may fall off when the lens is shaken (left). A (pure) slip-on connection is not the connection of choice for outdoor applications.

With lens hoods with slip-on or snap-on connections, attention should be paid to the outer diameter of the lens and the (technical) compatibility with the lens.

Yes. This is mandatory even for tulip or square lens hoods on wide angle lenses. It would not be important for round lens hoods on telephoto lenses.

The right material for the lens hoods

There are lens hoods made of plastic, metal, aluminum and rubber. The choice of material is up to the photographer.

✓✓✓ Plastic has the advantage over metal and aluminum that it is light and shocks are better absorbed. And if the lens fell on the lens hood, bayonet or filter threads are less stressed than lens hoods made of metal or aluminum.

✓✓ Aluminum is also light yet robuster than plastic. As for the absorption of shocks and the stress on the filter or bayonet thread when dropped, aluminum is better than metal and worse than plastic.

✓ Rubber lens hoods can be easily stowed away (compressed), but it does not withstand shocks as well as the other materials. But as one lens hood per lens is often sufficient, you can also fit the lens hood back to front to the unneeded lens and the stowage problem would be solved.

? Paper: On this website you can make your lens hood out of paper for free, if you have the time and inclination to do so. Print out the pattern, trim it and stick it together. There are many patterns for lens hoods available for lens manufacturers like Canon, Nikon, Pentax, Sigma, Tamron and Tokina.

When is a lens hood useful? And when not?

Image with orbs & artefacts


When photographing in a light source or in the reflection of a light source, the lens hood, despite its name cannot prevent image interferences such as artifacts or orbs from arising.

But some photographers use these as a stylistic device and then snap better without the lens hood.

You should avoid photographing with the flash and lens hood together. The lens hood can shadow the flash downwards and it does not produce a nice picture.

No, lens hoods are also used in the photo studio because stray light occurs there too and light sources must be screened.

Topic: Color - Beware of garishly colored lens hoods


Colored lens hoods can be reflected in the photo objects, so cameras, lenses and lens hoods are mostly black.

If you really want to have a colored lens hood, you should make sure that the inside is matte black. The lens hood shown here certainly leads to a red cast shot.

Lens hoods that are dark velvet-lined internally are ideal.

How much do lens hoods cost?

Prices range from $7 for no-name lens hoods from Shenzhenin China to $60 for branded lens hoods for upscale telephoto lenses.

On average, a lens hood purchased online with delivery costs approximately $10.

lens-shade-Canon EW-63C

The best selling lens hood costs €14.99 on Amazon. It is the original Canon EW-63C for the Canon EF-S 18-55mm f/3.5-5.6 IS STM lens. The lens in turn is part of the standard equipment of the Canon D70 camera.

The biggest price jump is between no-name products and brand-name products. You can use a no-name lens hood with success or be disappointed because there are different degrees of hardness of the plastic. If the lens hood should sit firmly on the lens and should be 100% compatible with the lens, you would be better taking the original lens hood from the manufacturer.

When buying a bicycle lock the price is set at 10% of the bicycle price. A lens hood protects the lens as well, so 10% is a good rule of thumb.

Or so a photographer told me. For a $150 lens, $15 is not too much for the lens hood.
