So what
....the 18-55 has 37mm of range. For a standard lens 18-55 makes a lot of sense...moderate wide angle to portrait.
But get the lens you need.
My FE 10-17 has only 7 mm of range...my 12-24...has only 12 mm of range...but my Sigma 150 - 500 has....350mm of range.
My prime lenses...50mm, 40mm, 70mm....have only one focal length.
But they all fulfill a photographic need for me.
But rather than have a couple of lenses and if one wants one lens to fufill a lot of needs than something like the Tamron 18-270mm (think it's the Tamron) goes a long way.
