Not exactly. The EOS-1 was introduced in 1989. Also introduced that year was its holy trinity of lenses: 28-80 f/2.8-4, 20-35 f/2.8 and 80-200 f/2.8. The first four lenses introduced for the EOS system, in 1987, were the 50 f/1.8, 35-105 f/3.5-4.5, 35-70 f/3.5-4.5 and 100-300 f/5.6, definitely not high end. There were some very high end lenses introduced between 1987 and 1989 but in 1987, the Canon F1 using the FD lens mount was king and Canon was introducing lenses for both the FD and EOS mounts. There was even an 85 f/1.2 for the FD mount. The 50 f/1.0 was the first lens that Canon introduced for the EOS mount while stating that it could not be made for the FD mount. That was in 1989.
In 1987, I owned a serious FD system and was extremely annoyed that Canon didn't see fit to make an FD body that had an in-focus indicator in the viewfinder. It wouldn't have been difficult, although there was no way that an FD lens could have been controlled by an FD body. There simply wasn't room in the mount.
