Description
The Canon FD 70-210mm f/4 was a high-quality telephoto zoom lens introduced in the ‘New FD’ era (early 1980s). Its key feature was the constant f/4 maximum aperture throughout the entire zoom range, which was a significant advantage over variable aperture zooms, especially for manual exposure or consistent performance. It utilized the New FD bayonet mount, offered excellent optical performance with S.S.C. coating, and often featured a convenient one-touch (push-pull) zoom/focus mechanism. It was popular among serious amateurs for its versatility and quality.
