Pentax-A* SMC 200mm f/2.8 ED
Summary
The SMC Pentax-A* 200mm f/2.8 ED is a premium manual-focus telephoto prime introduced in 1984 and produced until 1998, designed for full-frame K-mount film cameras. As part of the elite A* (Star) series, it features two Extra-low Dispersion (ED) elements for superior correction of chromatic aberration and delivers exceptional sharpness and contrast—even wide open. It uses a 6-element - 6-group optical design, Super Multi-Coating (SMC), and an 8-blade automatic diaphragm. The lens stops down to f/32, focuses as close as 1.8 meters, and provides 0.14× magnification. It uses a 77mm filter thread, weighs 850g, and measures 91 × 138mm. It includes a built-in sliding hood, plastic clip-on cap, and was originally paired with the HF-185 hard case or S90-160 soft case. The aperture ring includes an A setting for full automation on compatible bodies.
