Yes, focus at 15ft set to 40mm then zoom to 150 mm and the focus goes way out. Steve.

Yep, all of these zooms do that. Even the 12-60 and 50-200 SWD zooms for the Olympus DSLR's I used before do that. Zoom is the generic term, but these really are all varifocal lenses. I have not owned a "true" zoom that held focus when zoomed while set to a specific distance for a long time. Pre-AF (prior to 1985) for sure. Last one I remember using was a Vivitar Series 1 90-180mm f4.5 Flat Field in Nikon F mount, a superb lens.

I'm sure they still exist in some line, but none of these micro zooms are.
