Hoya Lenses

In September 2006 I acquired a Pentax Digital SLR, a K110D.

The camera has a standard Pentax K lens mount,  More information on these here.

Whilst looking for a 'longer' lens I came across the 'Hoya'  100-300mm zoom that is shown elsewhere and won it on E-bay.

 This lens caught my imagination as I hadn't heard of this firm making lenses, only filters, so I did as much research as I could and these are the results.
