Canon EOS 650 Transparent

Introduced in 1987, the Canon EOS 650 Transparent was a significant variant of the original EOS 650, Canon's first camera featuring the revolutionary EF lens mount and fully electronic autofocus system. The standard EOS 650 was a landmark product, marking Canon's decisive entry into the autofocus SLR market dominated by Minolta and Nikon. It introduced the EF mount, which replaced the mechanical FD bayonet mount with an entirely electronic connection between lens and body, enabling autofocus and other electronic features. This shift was fundamental, driving Canon's lens system design for decades to come. The EOS 650 incorporated Canon's sophisticated 5-zone focusing system, a major step up from simpler competitor systems at the time, and integrated motorized film advance and rewind, significantly speeding up operation compared to manual SLRs. Its introduction established the foundation for Canon's successful EOS series and influenced autofocus SLR design across the industry. The "Transparent" designation typically denotes a non-working or cutaway model, used for exhibition and education to showcase the internal mechanics, particularly the intricate electronic autofocus and exposure systems that defined this generation of cameras. While sharing the core technological breakthroughs of the standard EOS 650, the Transparent version serves primarily as a historical artifact illustrating the camera's complex internal workings.
