Meyer-Optik Gorlitz Primoplan 75mm f/1.9 II Lens for Pentax K

Meyer-Optik Gorlitz Primoplan 75mm f/1.9 II Overview

Characterized by its speed and portrait-length field of view, the Primoplan 75mm f/1.9 II from Meyer-Optik Gorlitz is a sophisticated, yet simple prime for Pentax K-mount cameras. The bright f/1.9 maximum aperture pairs well with the short telephoto focal length to allow working with shallow depth of field and selective focusing techniques, and the fast aperture also benefits working in difficult lighting conditions. Its manual focus design further offers control when focusing down to 2.5', and a 15 rounded-blade diaphragm contributes to a smooth bokeh quality. The five elements, four groups optical design makes use of Schott glass for a high degree of clarity, and an O'Hara Anti Reflex Coating has also been applied to limit flare and surface reflections for improved contrast and color accuracy. Additionally, the lens features an anodized aluminum housing that is durable, lightweight, and contributes to smooth, silent focusing performance.

Portrait-length prime is designed for full-frame Pentax K-mount cameras, however it can also be used on APS-C models where it will provide a 112.5mm equivalent focal length.

Fast f/1.9 maximum aperture allows for extensive control over depth of field, for working with selective focus techniques, and also benefits working in low-light conditions.

Inspired by the original Cooke triplet optical design, this lens uses a five elements, four groups layout in which the central dispersion element is surrounded by two groups of converging elements, and the rear element has a biconvex converging design to produce notable smoothness and clarity.

Schott glass is used for high clarity and contrast, and each of the elements feature an O'Hara Anti Reflex Coating to suppress lens flare and ghosting for color neutrality.

Manual focus design permits working with subjects as close as 2.5' away.

Fifteen rounded diaphragm blades contribute to a smooth bokeh quality.

Front 52mm filter thread is consistent throughout the Meyer-Optik Gorlitz version II lens series.
