The EOS 620, marketed in May, 1987 - was introduced barely a few months after the debut of the Canon EOS 650 in March, 1987. Unlike the 650, the 620 was promoted as a camera with a higher technical specification; its shutter was designed to meet the needs of the mid- to top-level amateur, with the camera primarily aimed to assist both levels of photographers. Basically, it carries more technical specifications than the entry level EOS650. Its sales targets were mid-level and advanced amateur photographers but Canon did use the EOS 620 as a promotional tool to entice professional photographers at major sporting events in trying out the EOS System, an effort that went well until the 1988 Summer Olympics Games in Seoul. The EOS 620 was replaced two years after introduction in 1989 with the EOS 630 camera. Despite its relatively short appearance (for an analog SLR), the EOS 620 does have followers in the used market for a while as it has a higher sync speed of 1/250 second, a stop faster than what the EOS 630 has! And the Canon EOS 620 was also the first EOS camera model that employed the Programmed Shift Function and an integrated Auto-Bracketing Control.
