I just read the interview with Yasuyuki Nagata of Sony, in which he used the term "lens attachment rate." Being relatively new to digital photography, I'd never heard this term before. So I Googled it; the only results were links to this interview. Hmmm. So I went to Wikipedia and entered it as a search term--and got the no results message. Can anyone tell me what Mr. Nagata is referring to and why it is germane? Thanks!
