Just giving those who utilize the Zone System (or, just like using a spot meter) a heads up that I'm selling a nice Asahi Pentax Digital Spotmeter on eBay right now. I believe this is the same model that Ansel Adams himself used... This one is in very nice condition overall. The glass does have some issues, but it doesn't seem to affect accuracy, so this one may turn out to be a bargain! It also come with original case.
