I have that worry too, the Pentax 28-45 is like that.
You will never have full sharpness with wide to normal focal length zooms, with any brand unless the lens is highly oversized, heavy and expensive. That's because the angle of light path varies a lot from wide to normal, such that sharpness is compromised. If you want sharpness for wide to normal focal length, use prime lenses up to about 35mm FF equivalent. For long FL, 50mm FF equ. and up, zoom can deliver very good sharpness across the frame, especially from 100mm equ. FL and above. If I was full time professional photographer wanting to max out of image resolution with any camera format, I'd use only prime lenses up to 100mm FF equivalent.

I didn't know it's a cliché. For me it is a great picture. And if many have photographed that same subject many times, much less have photographed it at night with a 100Mpixels camera.
You'll probably find a million smartphone shots only good to share online, but if you would print that same picture on 40" metallic or fujiflex or fuji maxima photo paper and frame it, it'd be jaw dropping and many people would stop to contemplate for a moment.
