==== Summary ====
The SMC Pentax 67 55-100mm f/4.5 is a rare and highly regarded wide-to-standard zoom introduced in 1998 for the Pentax 6×7 medium format system. It offered a 35mm equivalent focal range of approximately 28–50mm. Designed for landscape, travel, and general-purpose photography, it gave medium-format shooters the flexibility of framing without swapping primes—a major convenience in the field. Optically, it features an 11-element, 9-group design with Super Multi-Coating (SMC) and an 8-blade automatic diaphragm, stopping down to f/32. The lens focuses as close as 60cm, delivering a 0.21× magnification ratio, and uses a massive 95 mm filter thread. It weighs 1210g, measures 103 × 120 mm, and includes a manual aperture ring (no “A” setting). There’s no internal focusing or weather sealing, and the front element rotates during focusing. A dedicated PH-RBB95 hood and S120-160 soft case were typically bundled.
