I'm currently looking at a new lens. Most likely going to be the 17-55mm/2.8. I know this model doesn't come with a lens hood. Do I need to purchase a lens hood? Is this going to have a dramatic affect on results?
Also, what about a clear protection filter? I was looking at this one: http://www.bhphotovideo.com …007_Protection_Clear.html![]()
I know there's lots of people complaining about dust and the 17-55mm lens. I don't want to spend another $90 bucks, but will if it means protecting my investment.
