Description — Pentax 105mm f/2.8
The Pentax 105mm f/2.8 Super Takumar is a prime telephoto lens built for the M42 screw mount, designed to cover full-frame sensor formats. With a fixed focal length of 105mm and a maximum aperture of f/2.8, it sits in the telephoto range and offers a moderately wide aperture for this class of lens. Focusing is manual only, placing full control in the photographer's hands — a characteristic well suited to deliberate, considered shooting styles.
The lens is notably compact for its specification, tipping the scales at just 290g, and accepts filters via a 49mm thread, a convenient and widely available size. Originally designed for SLR camera systems, the M42 screw mount makes this lens adaptable to a wide range of modern bodies through commonly available third-party adapters, extending its usability well beyond its original era. There is no image stabilization, so steady technique is important when shooting handheld.
