Infinty on kit lens

I have looked and looked and can't seem to find an infinity symbol on the Pentax 18-55mm kit lens that came with my K-X. Can somebody tell me where I get infinity on that lens-or if it's even possible? Thanks.

If you are looking through the viewfinder then rotate the focus ring all the way clockwise (so inifnity would be on the far left side of the focus ring), and then obviously everything would be opposite if you were directly facing the lens.

Are you saying I will see it inside-on the bottom of the screen with the other stuff that's there? It sure isn't on the outside of the lens anywhere.

When the lens is on the camera (the mount is facing you) , you turn the focus ring clockwise all the way to its stop, then the infinity point should be on the top .

No you will not see any indication of an infinity focus. I was just stating a reference point to tell you to turn either clock or counter clockwise. The DAL (kit) lenses do not have any focucs distance indicators on the lens where as all other lenses will have something along the focusing ring that will indicate focus distance in feet and meters.

To be clear: the K-x kit lens doesn't have a *marking* for infinity. but it most certainly can focus at infinity - just turn the focus ring all the way in the correct direction. One direction focuses as closes as possible, the other focuses as far as possible. You shouldn't need a marking to tell you which is which - just look in the viewfinder at how the focus changes when you turn the focus ring.

Got it. I was just used to seeing the symbol on my older lenses. Thanks, everybody.

Important!

Modern auto-focus lenses are generally designed so that the lens turns past infinity. If you turn it all the way to the end and expect everything to be in focus, you'll get disappointing results.

This allows for less precision in manufacturing (which results in cheaper lenses).

Thank you for saying that! My Kx kit lens does that and I just thought that I was crazy, nice to know that it's a common thing.

Not just common, but by design.
