Reading Many Canon Lenses Review

I cannot stop reading this review of Canon lenses. There are simply way too many reviews on this site. I am definitely going to read his site for a while before I can decide on which lens to buy. I would consider myself a serious amateur photographer. I shoot a bit of everything nowadays and I prefer to have a lens that can do that function for me. When reading his reviews, I think I know that a super zoom lens is the lens for me. However, I am still not sure if I can take the hit on image quality. I might go for two lenses combo. In other words, I might take two lenses with me on the go which is the 18-55 and 55-250 lens. Given those combination, I will be able to take many great and sharp shots. My only wish is for Canon to make those lenses f/2.8 so I do not have to carry primes.
