JUPITER - Jupiter 3 Clean and Lube 39mm CLA
Comprehensive clean and lubrication (CLA) guide for the Jupiter-3 lens This manual provides detailed instructions for maintaining the 39mm focus mount of this classic lens design. The document outlines the five main mechanism components—the 39mm mount, inner helical, outer helical with inner sleeve, and focus ring—and lists all necessary tools including precision screwdrivers, compartmented trays, solvents, and lubricating grease. Step-by-step procedures cover safe removal of the optical module, disassembly of the focus ring, and thorough cleaning of both inner and outer helical sections. The guide emphasizes critical maintenance practices such as preserving original component positions, creating scribe marks, and carefully managing guide pins that control focus travel. Special attention is given to cleaning the outer helical assembly while keeping the sleeve partially unscrewed to avoid misalignment, removing dried grease deposits using solvent and brushes, and applying fresh lubricant judiciously. The reassembly section details proper alignment techniques using tap positioning and guide pin marks to ensure correct rangefinder coupling and optimal focus performance. Optional procedures for securing set screws with lacquer are also discussed.
JUPITER - Jupiter 3 Contax Leica Conversion
Comprehensive technical guide for converting a Carl Zeiss Jena 5cm F1.5 Sonnar lens from Contax mount to Leica mount using a Jupiter-3 base. This manual covers the complete optical modification process, including identification of essential components (optics module, focus mount, shims), disassembly procedures, and adjustment techniques. The document provides precise specifications on focusing distances, back focal length calculations, and optical formulas required to ensure correct infinity focus. Detailed instructions explain how to separate the Zeiss optics module from its original mount, how to adapt the Jupiter-3 variable stand-off ring when necessary, and how to properly install the Zeiss optics into the Jupiter-3 focus mount. Complete equipment list (jeweler screwdrivers, aluminum, shim materials) and step-by-step procedures with illustrative photographs. Includes comparative analysis of focus travel requirements between the Zeiss standard configuration and Leica calibration. Essential resource for vintage camera enthusiasts and optical restoration technicians.
JUPITER - Jupiter 3 Exploded
Comprehensive technical guide featuring detailed exploded diagrams of the JUPITER-3 lens assembly, meticulously documented This resource provides a systematic breakdown of the complete optical system through professional component photography and clear labeling. The document begins with an overview identifying the three primary assemblies: the Focus Mount, Main Shim, and Assembled Optics Module. The Focus Mount section presents its intricate construction, detailing the 39mm Thread Mount, Outer Helical two-piece component with inner sleeve, and Inner Helical mechanism. The optics module breakdown encompasses all constituent elements including the Optical Fixture, Rear Triplet, F-Stop Ring, two-piece aperture ring, Coupling Ring, Aperture retaining Ring (configured as Variable Stand-Off Ring), and Main Shim. Each component is clearly identified through high-resolution photography and precise labeling to enable accurate identification and understanding of part relationships. This technical resource serves optical technicians, camera repair professionals, and restoration enthusiasts requiring detailed knowledge of the JUPITER-3 internal architecture. The exploded view presentation facilitates disassembly, reassembly, and maintenance procedures while providing essential reference documentation for anyone working with this classic lens system.
JUPITER - Jupiter 3 Focal Length Adjustment
Comprehensive focal length adjustment guide for Jupiter-3 lenses manufactured before 1964. This technical manual provides detailed procedures for adapting Jupiter-3 lenses with 39mm thread mount to ensure proper focus compatibility with Leica cameras, which are calibrated for a nominal focal length of 51.6mm rather than the standard 52.4mm. The guide explains the optical reasons behind infinity focus discrepancies and presents practical methodologies to resolve these issues. The guide covers lens disassembly techniques, optical surface polishing, rear triplet positioning, and main shim adjustment. Specific optical formulas and technical illustrations accompany step-by-step instructions. The document also addresses focal length extension using standoff shims. Procedures outlined are precise and require specialized tools including optical spanners and calipers. Topics include identification of focus errors through F-stop analysis, glass element removal and reinstallation, aperture mechanism protection, and iterative testing processes. This reference work serves lens repair technicians, vintage camera enthusiasts, and anyone seeking to optimize Jupiter-3 lens performance for superior image sharpness across the entire focus range.
