Re: Not "Substantial" between 15-85 vs 18-55, but substantial on Telephoto Lens

Is the image quality of 18-135 same as that of the the KIT lens? Are they really different? I do not meant the difference that is only noticeable in some top left corner at 100% magnification. If I take a picture of my kids running around in the center would I see any degradation in quality? Thanks in advance
