The Pentax Digital spot meter is one of the most Zone-System-friendly spot meters ever made, but the little window on the meter only lets you see Zones II through Zone VIII!
I've put a bit of my silver-smithing past to use and can modify your meter to show Zones 0 through XII.
You place an important shadow on Zone II and want to know just where that really bright highlight "falls" at a quick glance? With this modification, now you can. New Zone System sticker included in modification.
Please ship your meter to me at 24 Estambre Rd., Santa Fe, NM 87508. Include a return shipping label with the package. Insurance highly recommended. Estimated turn-around is 7 days (or less).
