18-135 zoom merely okay, not as good as the Nikon 18-140. Pentax 18-270 is sharper at all focal lengths than the 18-135.

You have a weak copy of the DA 18-135mm. Here's an excerpt from the Pentax Forums In-Depth review of the DA 18-270mm:

"If you plan on making larger prints or are concerned with speed or image quality, then this lens isn't for you. We may even go as far as saying that if you plan on owning multiple lenses, then this shouldn't be one of them. For enthusiasts who wish to complement their lens lineup with an all-in-one lens, we recommend the Pentax DA 18-135mm instead, as it's cheaper and offers weather sealing as well as slightly better image quality at the focal lengths that it covers."

In their test, sharpness is rated 6.0 for the 18-270, 7.0 for the 18-135.

Most shooters also rate the 18-250mm higher than the 18-270 (8.56 vs. 7.5 in the User Reviews at Pentax Forums). My 18-135 beats my 18-270 in virtually every way, as shown in these full-size images: https://picasaweb.google.com/100586096103361553535/18135Vs18250?authkey=Gv1sRgCNzC5b_4_qXRqQE#
