As everyone knows, I just got my camera and I'm new to this dslr thing. What kind of cleaning kit do I need to maintain the camera? Certain items that I will need? I have seen others talk about some type of "lens blower" and was wondering what type of "cleaning kit" should I purchase? Are these in any camera store? Walmart? Ebay? Thanks and sorry for the noob question. I just want to make sure that I take good care of my investment.
