Looking for advice on optimal use of overlapping zooms

That's helpful. I was also looking for recommendations for change in practice. Can I assume that over the range up to 45mm, the Pentax will be sharper just because it has a smaller range? Would there be other, perhaps more subtle, differences? Since my photography is reactive, rather than planned, I suspect I see things differently depending on which lens is on the camera. The most dramatic difference is in looking more aggressively for architectural detail when I have the telephoto. I suspect I could get more out of what I have by using them more intelligently.

You're right in the implication that it's at the telephoto end I feel the need for more sharpness.

Being a reactive photographer - that will change btw - it's important to stick with one set of gear or one general setup like a wide angle zoom and mid-tele zoom. It will soon become apparent what you're missing and you can aim to fill those gaps. If you change your gear around too much before you know what you're really looking for, a lot of $ is wasted with buying and selling. Ask me, for I know this.

The best way is to get out there and settle into a groove slowly. If you try to typecast yourself, it won't feel right.

And reacting to circumstances differently depending on which lens is on the camera is fine. If I want a quick shot of something, I'd rather have the wrong lens than the right lens and no shot due to swapping.
