DA 18-135mm - A good lens for traveling

I don't want to argue about the qualities of the DA 18-135. Many people are happy with it, fair enough.

However, it must be stated, that there have been and still are people here who look with envy at the Nikon 16-85, and have for years been hoping that Pentax will produce something similar.

Now I understand that Nikon is preparing an update, constant F4 16-85 !!

Common Pentax, you have the top travel body, give us the top travel zoom!
