Due to the shape in which lens are made up, while shooting up in broad sunlight or in evenings, you will have noticed the flare happening if you are not having a lens hood attached. The Nikon kit lens users will have to go ahead and try removing the lens hood as the kit lens does come with a petal hood. The canon people will already know what this is.
Lens Hood was an attempt to clear out the glare that hits you through the edges –
It just acts as a shade for the lens. The size n shape of lens hood depends on the nature of use.
The different types of Lens Hoods:
As you might have noticed on the vendor sites there are different hood types depending on the lens. For zoom lenses we mostly have the circular hood which is quite thick, the tamrons and sigma’s 70-300 mostly comes with this kind of lens hood. It blocks most of the light that enters through the side as the exposure of lens is narrower.
There is another variant of circular lens hood which is normally used on wide angle lenses to prevent vignette at the sides.
The trouble with circular hoods is the edges that the hood creates which can increase the risk of flares on your photos. This leads to the next type which is the square hood:
The square hoot tries to eliminate the short comings of circular hoods, as it covers the complete area of the scene and can be long as circular hoods but still provide you with a better image. The shortcomings on these hoods were the size and incompatibility to be carried around as it consumed more space. The tulip or the petal hoods were introduced with this change:
This tries to give in the coverage as good as rectangle hoods and also having cut edges to avoid the shortcomings of flare on circular hoods. Mostly the the petal hoods and cut off petal hoods are widely used, the canon dream 70-200mm 2.8 has a wonderful hood which appeals a lot of nikonians too.
Should I get a lens hood?
My answer is yes, please! It’s not only the protection that it provides to your precious glass, which is the most popular belief for a lens hood, but it is the quality on the edges that matter. As you progress through your skills you will always want your image to be sharp from the edge to edge. So once you have this into consideration keeping a lens hood on will yeild you best results.
There are situations where this will fail, when you shoot using an inbuilt flash or an external overhead you can simply remove them or in situations where you are shooting ultra wide. But for otherwise, you can keep the hood on and you will find the difference on edges. You will rarely find a professional photographer vote against the lens hood!
Thank you guys, a few goodies for Nikon fans!
