A Little Look at a Lens - The Pentax (K) 28mm F2 'Hollywood'

Apparently a collaboration between Zeiss and Pentax in the early 70's resulted in this Pentax badged Zeiss Distagon design with a floating element. The partnership lasted for a year or so, until Zeiss teamed up with Yashica / Contax. The lens is very highly regarded and quite rare. Neither I nor the seller knew what it was when I bought it many years ago, and it was only recently - upon acquiring a Pentak K-1 full frame digital - that I noticed what it was.
