I have often wondered if quantarray lenses are any good. I have a long history of nikon film cameras and to this day still have my N65 and N80. I have 2 lenses that i acquired at the time i bought my film cameras. One is a 28-90mm D kit lense quantarray for nikon and the other is a 70-300mm D quantarray for nikon. While i was often able to get decent shots with my film cameras using these lenses i have not had as much success using them on my D100 and as a result I never use them. Who makes quantarray lenses anyway?
