Problem with sigma Zoom

Hi Everyone,

I have recently aquired an older Sigma zoom 28-80mm 1:3.5-5.6 Aspherical and it seems to work ok with the K100D super. The only problem is that it will not zoom down to 28 ...it stops at 35. It does not feel like it is jamming and it feels like a hard stop.

Am I missing something or do I have a problem?

Cheers
Keith

Doesn't have a macro switch on it somewhere?

Thanks for that Arpe - can't find any switch/buttons.
Cheers

Shake the lens. Is there something rattling inside?

There is a rattle when I shake it but another of my good lenses makes the same sound.

Take the lens off the camera, check if it still happens, see if there's any obvious reason?

Are you sure there is no Macro switch on the side of the lens? Sorry to sound like a nag but I have the lens and if the switch is up the lens will not move.
