Since 1959, every Nikkor lens made for their SLRs has fit every Nikon camera made. The compatibility is bidirectional - you can use a shiny new ED-IF "I" series AF lens on a 1959 Nikon F and you can use a 1959 stopdown F lens on a Nikon N90 body. Automation is limited to the capabilities of the older component, but every Nikon SLR can be used with every Nikkor SLR lens and vice versa - a claim to which Nikon is the sole possessor. A commitment to the investment YOU have made in their optics.
Contax has changed it's SLR mount four times, Pentax twice, Canon three times, Minolta twice, Leica couldn't get it right OR keep up to date - and every pro who invested in a suite of expensive optics from them lost the capability to upgrade their technology without annihilating their entire pre-existing and extremely expensive system. No established manufacturer of a major pro SLR system has maintained Nikon's dedication to avoiding inherent (planned) obsolescence.更多精彩文章及讨论,请光临枫下论坛 rolia.net
