Steve,
Since my Pentax Accessories Manual indicates that the Telephoto Adapter for the AF-280T (AFT-1) gives a greater concentration of the flash beam with telephoto lenses in the 85mm - 200mm range, the flash without the adapter should cover up to a 85mm lens. I have used the AF-280T (w/o Telephoto Adapter) with my 85mm lens and it works great on an LX.
I hope this helps.
Regards,
