I currently have two Quantaray lenses (Ritz Camera Store-Brand). One is a 28-90 1:3.5-5.6 Zoom Lens, and the other a 70-300 1:4-5.6 Zoom Lens. My pictures always seem to come out just a tad blurry, they even seem blurry when I'm looking through the view-finder.
I was wondering if the optics are to blame and if buying a more expensive, name-brand lens would help; or if there are other things I need to work on.
Any suggestions are greatly appreciated.
