Alphatracks writes on this very topic. I found it interesting that according to the article all Sony Alpha lens are shipped to include a lens hood. I wish Canon did the same.
There are certain situations where a lens shade is unnecessary, or even detrimental to making good images. I’ll discuss the specific conditions when you shouldn’t use a lens shade in a moment. First, however, I want to look at why you should attach a hood almost every time you take a lens out of your bag. [via Alphatracks]
Essentially you should use a hood to avoid glare in your photos. That’s the why. In response to the when, I keep hoods on all of my lenses and have found no reason to take them off yet.
