Photoclubalpha

Any suggestions on what filter i need for general purpose & photograpy of aircraft, some of my shots i feel could do with some defenition on clouds and nice blue skies etc, Tried a filter before but my camera wouldnt autofocus for some strange reason although i may add i got them on ebay!

Hoya have a series of Polarizer filters (HRT) that are slim and 25% "brighter", you only loose 1 f-Stop
