Unlike Drew, I like my Zone stickers and have one on all of my meters. Ignore the fake grey scale though; it's not meant to be an accurate representation. The nice thing about using the Pentax meter with the Zone sticker together with the Zone System is that you can simply set the meter index mark opposite whichever Zone you want to place the shadow in and read your exposure off the dial, no stopping down from the meter reading needed. It's no big deal, just saves a step.
