Hi, I bought the Canon Rebel Xsi with the 18-55mm and 75-300mm kit all brand new for 650$ I was just wondering if anyone has any experience with this kit? And what Pros and Cons they feel come with the kit itself. Also this is my first camera, is there any really necessary accessories that anyone can suggest I buy right away? Anything from as small as a lens cleaning pen to any new lenses I should buy. Thanks.
