I am new to DSLRs. Just bought Canon EOS 400d. The Focal lenght of this kit lens is doing fine for me, I mean my requirements. The 18-55mm. I want to know if theres any lens which sharper than this? So I can replace this lens for general photography. I will be buying a Wide Angle 10-22 MM LEns for the same. But till than I have some areas to cover which fall under 18 mm. Also, I need an appropriate zoom like 55 mm so I can do my other things without any problem. So Is there any lens which I can buy to replace this kit lens which is sharper than this at least at 18 mm.
