Filter
ok... the UV filter was originally invented mainly for the film cameras, this is because the UV light that penetrates the lens will "spoil" the film..
thus manufacturers came out with UV filter to prevent UV light from entering the camera and spoiling the film..
But now, we are in the
digital age, even if the UV light passes through the lens and reach the sensor,
our sensor won't be affected in any way, and our pics will not be affected.
That means UV filter, in the digital age, is
just a piece of glass place in front of the lens to protect the lens. You break a filter, at most u pay $100, but if u break or scratch ur lens glass, expect to pay more than hundreds and maybe thousands to replace it. This is why a UV filter is often also called a protective "cover".
Whether sunlight or night or snow or blizzard, use it for its protective purposes.
Lens hood
For the lens hood, it serves 2 purpose. (a) to prevent unwanted light to enter the lens from the sides so as to reduce
flaring (b) to protect the lens element in front.
This is an example of flaring:
In this scene, the sun is on my left and is very very very strong, and without the hood to block out the light on the left, this is the flaring u will get.
In conclusion
(A) a filter is a MUST (protective purposes).
(B) use lens hood in
strong sunlight /
strong sources of light conditions, and if the environment is rough eg. in the jungle, use the lens hood as an additional source of protection for your lens. If lets say u are at
night at esplanade shooting the river, the place is pretty calm, u can dun use the hood.
