Thanks. After posting my previous response I re-Googled and did come up with a Chines manufacturer. They have one for the K10D and DS. at $30. I checked eBay and came up with this http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=180326554642&fromMakeTrack=true&ssPageName=VIP:watchlink:top:en which is even better, includes tweezers, etc. The instructions couldn't be clearer than those at this link. That said, I'm gonna wait to see what I find from the test Steve suggested. And also see what results I get taking David's suggestion of paying attention to the focus indicator in the viewfinder instead of what I see through the lens. But all this brings up another question: What is the difference between "open aperture" and "stopped down" metering? Would that be metering before and after setting exposure, assuming you're not shooting wide open? And what are the pros and cons?
