I have a Z1 with the FA 28-105 zoom lens and have just pruchased the K10D. I can assure you that this particular lens works fine on the K10, even the motorised zoom of the lens functions fine. You can zoom from one extreme to the other at the 'bat of an eyelid' if required. I have not tried zooming whilst shooting with a slow shutter speed yet. That should be interesting on the K10.

Hi Matt
Are you saying that the firmware has already been updated? I bought my K10 last week and the firmware version says 1.0 when I switch on with menu button held down. ??

In answer to the query about 3 levels of antishake, are Pentax referring
1) Antishake on/off for picture taking.
2) Dust removal at startup
3) Dust removal only on request from menu

Hi 'Ammonyte' Glad you said "I think". As an istDS user I have actually used mine via a PC. see also another post by an istDS2 user who has also done so.

Having just upgraded my firmware to 2.02 , I have just seen on a Yahoo Pentax user forum that after upgrading that the PC software for controlling the camera from the PC no longer works. I have not had the chance to confirm this myself yet but I intend to do so at the first opportunity. I will then post again with my findings when I have done so.
