Radial Star

Rediscovered my Cokin P series filters.. Picked them up second hand for a pittance from a Cash Converters in Carlisle several years back... For this I employed the Radial Zoom P185 and Star8 P056.. I hear both where very popular back in the Pre-Digital Day.. With the power of Photoshop many image makers are ditching their old addontothefrontoflenses filters... I'll buy up any that are going spare?
