I also disagree. First, I have one and it surprises me how sharp it is at 300mm. It may not be as sharp as a prime lens, but it sure is pretty good and, to me, worth the trade-off for convenience of all-in-one performance. The attached image was taken at 300mm, the blow up has no additional processing, and nothing was done to enhance sharpness.
It may be sharp for a kit lens but here is my problem. I had to buy a Sigma 70-200, f/2.8. Once I saw how much sharper it was, I eventually switched over to their better lenses. Today, I own four of them plus the 18-300. I had not used that lens for several years until last night because I needed to on a second body.
I agree with you about the convenience. Your lens is so much more convenient to carry around and use. However, the quality is the deciding factor for me. I looked at your pictures. The uncropped one is not that sharp. I do not really judge a picture by zooming in a lot but I can really tell the difference. If you dismiss what I say, I suggest that you try one of the better lenses and see if you can tell the difference.
Prime lenses. I know that they are even sharper but I prefer the convenience and flexibility of the zooms. And this is despite their heft and size.
This is a good discussion. Thanks to all for joining it.
