I'm a bit confused on where to start with buying a new lens. Could anyone help me or perhaps give a few suggestions on buying a lens or examples of lenses you would recommend. The camera I have is a Canon Rebel K2. I have looked on the Canon website and gone through the lenses however I dont know what I should start with. I just started photography this year and currently the only lens that I own is the one that came with the camera that is a 28-90 mm. All suggestions are welcome.
