==== Summary ====
The SMC Pentax-M 200mm f/4 is a compact manual-focus telephoto prime lens introduced in 1977 and produced until 1984, designed for Pentax K-mount 35mm DSLRs and compatible with APS-C and full-frame digital SLRs. It features a 6-element/5-group optical design, an 8-blade automatic diaphragm, and Super Multi-Coating (SMC) for improved contrast and flare resistance. With a constant f/4 aperture, it delivers a 12° diagonal field of view on full-frame (or ~8° on APS-C), making it ideal for landscape, wildlife, and sports photography—especially in daylight. The lens focuses down to 2 meters, offers a 0.13× magnification, and uses a 52mm filter thread. It weighs just 405g, measures 64 × 111mm, and includes a built-in sliding hood for added flare protection.
