Question about DA35 2.4 lens

Since this lens extends slightly at certain focal lengths and the zoom (EDIT- focus) ring cannot be manually operated when in autofocus mode, is there a camera setting that will return the lens to its minimum length when powered off? I feel like the lens would be more secure in storage in the unextended position.

I'm kind of anal about this (and other lenses), especially since it's a tight fit in my camera bag. I've found it easiest to just hold down the lens release button to disengage the AF screw and then turn the focus ring to infinity. You could also switch to MF if your camera has that option, but that's slower and it's easy to forget to switch it back. Hope that helps!

EDIT: realized I didn't answer the actual question! So: as far as I know there's no camera setting that allows this, but you can use the workaround above. After a while it's pretty routine.

Pop the cap on and hit the AF. Mine always sucks in to infinity.

Just focus on a distant object before you turn it off. That will pull it in.

Are you talking about a different lens? The 35mm isn't a zoom lens. And no, there is no lens retraction; that feature was discontinued when Pentax stopped making power zoom lenses.

I think he meant the focus ring.

Yes I meant the focus ring of course. Thanks everyone for the tips.

Yes, you can switch to MF and focus to infinity. That should be the lens at its smallest.
Some lenses have internal focusing and they don't change size. Similarly for zoom lenses.
But the DA 35mm is so small I don't think you save much space by focusing it to its smallest length. I also don't think the lens is vulnerable if its "extended"
