I purchased the
Metz 58 AF-1 TTL and it will arrive soon. This flash has auto zoom but will the autozoom work with a SigmaZoom Super Wide Angle 18-200mm f/3.5-6.3 DC Aspherical (IF) Lens for Pentax Digital SLR?

I can't tell exactly what mount this lens is other than it is for Pentax Digital SLR.
The Metz has autozooming from 28-105mm. This lense is 18-200mm. Would the flash be able to read the zoom of the lense, or do I need a pentax DA lens,

Confused.

The flash does not read the lens...

Normally the flash is controlled by the camera body - The lens info is part of the exif that the camera included anyway (i.e. aperture and focal lenght) with the captured images

-> The body know the focal lenght (and the crop-factor) so it should be able to control the flash properly if it's designed correctly!
