Sigma 70-210mm F4.5 Zoom Kappa II
Launched October 1982

One of the classic focal lengths, the 70-210 was a staple of photographers in the 1980s; Sigma’s inexpensive model was announced in October 1982 for under £100, and as the specifications show looked pretty impressive! The bracketed specifications are taken from the manual.
