Koolpc, why do you bother to ask for people's opinion if you're just going to ignore it anyway?

Problems caused by filters are usually not subtle. This was taken with the
camera facing the afternoon sun:

Lens hoods are a completely different matter. A lens hood
can cut down on lens flare and reflections under some
circumstances. A lens hood probably wouldn't have helped
the photo in my previous post. In a less extreme case where
the sun or a street light shines on the lens from a greater
angle, a lens hood can help to cut down flare and
reflections. Unlike the case of a clear or UV filter, the
quality of materials used in a lens hood has no effect
on image quality. Once the hood fits properly and the
opening is large enough that it doesn't obstruct the
field of view, a cheap hood is just as good as a high
quality hood.

A Chinese copy of the Canon EW-60C is about 2 including
postage on eBay. I would avoid the bigger 'flower' type of
hood on the 18-55mm because they tend to cause problems
at the 18mm (wide) end of the zoom range:

No. The thing really is that cheap filters are a constant source of minor degradation in picture quality, and an occasional source of major degradation in picture quality.

Always. Lens hoods never do anything bad, and occasionally do something good.

A persons opinion is just that, an opinion. Doesn't mean i should accept that opinion!

Canon EW-60C 11-17 on eBay and Amazon.

Chinese copy of same. 2 on eBay.

Avoid bigger or more complicated hoods because the
front of the 18-55mm rotates during focusing and because
of the issues mentioned in post #13.

Here is what can happen with any filter, even with a lens hood on. This was a CPL filter
