Pentax smc Pentax 200mm f/2.5 - Pentax K Mount

The smc Pentax 200mm f/2.5 is a fast, manual-focus telephoto lens from the K-series era. Known for its robust all-metal construction and large front element, it offers a significantly brighter viewfinder image and shallower depth of field than the more common f/4 version. It is an excellent choice for portraiture and low-light sports or wildlife photography on both film and digital K-mount bodies. Prospective buyers should check for smoothness in the large focusing ring, as the lubricant can thicken over time. Given the age and weight of the internal glass elements, SDS inspects for any signs of element separation or internal haze. The built-in retractable lens hood should slide freely and stay in position. Verify that the diaphragm is free from oil and snaps shut instantly.
