I'm new to photography. Would appreciate if someone can answer my questions.
1) From what I understand, lens hood helps in protecting the lens as well as reducing flare. Filters act as a protection for the lens. Thus, are they essentially the same just that filters are less bulky?
1.1) Does anyone put on a filter and then a lens hood on top?
1.2) Are lens hood expensive?
2) It is possible to test lens like how we test cameras before buying them?
Thanks in advance!
