Looking to add a little something extra to my travel package, a little closer and a more reach, P20 & P14-45 Budget and size are important to me and am currently working on acquiring the new P12-32 compact and selling the P14-45. My options are 1, Just stick to cropping. Served me OK, free and not extras to carry. 2, Set of tubes, most likely Kenko, Meike or Fotga, cheap, not too much bulk, but to me unknown I.Q. 3, stock up on extra lenses . What are your thoughts. Thank you.
