I doubt it's a conspiracy, the camera and lens database appears to be the poor stepchild in this operation. It took two emails and a month to get the Canon G15 added last year. Then there was a flurry of Canon gear updates. Perhaps if the Nikon users inundate
cameras@pbase.com with requests, some will be added. I think the database is useful as a source of input when one is considering new gear, and also interesting as an archive or encyclopedia of photo gear. The coverage of films has been spotty also. As one who still shoots film, some of it in cameras from the 1940s and 50s, I have more than passing interest in such things.
