[QUOTE="WayneF, post: 369210, member: 12496"] The middle grey result is correct. That is a big feat for a meter. Meters don't have any human smart to recognize the scene or the subject or anything. They don't know what it is, or how it ought to be. They just see a blob of light. They will put it in the middle, not too bright, not too dark. then the details are up to us. :) But technically, it is not 18%. Nikon, Canon and Sekonic use 12.5% (spec in the Sekonic manuals). Minolta, Pentax, and Kenko (bought Minolta meters) use 14%. That's a very minor difference. Kodak always used to say (published instruction sheet) to open 1/2 stop more if metering from their 18% gray card, which makes that result be about 12%. Kodak sold off their gray card business nearly 20 years ago, and this little note was lost. 18% was a Ansel Adam thing, about his Zone System in the 1930s.
